+- a .vsh is a v shell script and can be executed as is, no need to use v ...
+- in .vsh file there is no need for a main() function
+- these scripts can be used for examples or instruction scripts e.g. an installs script

+V allows for easily using text templates, expanded at compile time to
+V functions, that efficiently produce text output. This is especially
+useful for templated HTML views, but the mechanism is general enough
+to be used for other kinds of text output also.
+
+# Template directives
+
+Each template directive begins with an `@` sign.
+Some directives contain a `{}` block, others only have `''` (string) parameters.
+
+Newlines on the beginning and end are ignored in `{}` blocks,
+otherwise this (see [if](#if) for this syntax):
+
+```html
+@if bool_val {
+ This is shown if bool_val is true
+}
+```
+
+... would output:
+
+```html
+
+ This is shown if bool_val is true
+
+```
+
+... which is less readable.
+
+## if
+
+The if directive, consists of three parts, the `@if` tag, the condition (same syntax like in V)
+and the `{}` block, where you can write html, which will be rendered if the condition is true:
+
+```
+@if {}
+```
+
+### Example
+
+```html
+@if bool_val {
+ This is shown if bool_val is true
+}
+```
+
+One-liner:
+
+```html
+@if bool_val { This is shown if bool_val is true }
+```
+
+The first example would result in:
+
+```html
+ This is shown if bool_val is true
+```
+
+... while the one-liner results in:
+
+```html
+This is shown if bool_val is true
+```
+
+## for
+
+The for directive consists of three parts, the `@for` tag,
+the condition (same syntax like in V) and the `{}` block,
+where you can write text, rendered for each iteration of the loop:
+
+```
+@for {}
+```
+
+### Example for @for
+
+```html
+@for i, val in my_vals {
+ $i - $val
+}
+```
+
+One-liner:
+
+```html
+@for i, val in my_vals { $i - $val }
+```
+
+The first example would result in:
+
+```html
+ 0 - "First"
+ 1 - "Second"
+ 2 - "Third"
+ ...
+```
+
+... while the one-liner results in:
+
+```html
+0 - "First"
+1 - "Second"
+2 - "Third"
+...
+```
+
+You can also write (and all other for condition syntaxes that are allowed in V):
+
+```html
+@for i = 0; i < 5; i++ {
+ $i
+}
+```
+
+## include
+
+The include directive is for including other html files (which will be processed as well)
+and consists of two parts, the `@include` tag and a following `''` string.
+The path parameter is relative to the template file being called.
+
+### Example for the folder structure of a project using templates:
+
+```
+Project root
+/templates
+ - index.html
+ /headers
+ - base.html
+```
+
+`index.html`
+
+```html
+
+@include 'header/base'
+```
+
+> Note that there shouldn't be a file suffix,
+> it is automatically appended and only allows `html` files.
+
+
+## js
+
+The js directive consists of two parts, the `@js` tag and `''` string,
+where you can insert your src
+
+```
+@js ''
+```
+
+### Example for the @js directive:
+
+```html
+@js 'myscripts.js'
+```
+
+# Variables
+
+All variables, which are declared before the $tmpl can be used through the `@{my_var}` syntax.
+It's also possible to use properties of structs here like `@{my_struct.prop}`.
+
+# Escaping
+
+The `@` symbol starts a template directive. If you need to use `@` as a regular
+character within a template, escape it by using a double `@` like this: `@@`.

+# HeroDB Model Creation Instructions for AI
+
+## Overview
+
+This document provides clear instructions for AI agents to create new HeroDB models similar to `comment.v`. These models are used to store structured data in Redis using the HeroDB system.
+
+## Key Concepts
+
+- Each model represents a data type stored in Redis hash sets
+- Models must implement serialization/deserialization using the `encoder` module
+- Models inherit from the `Base` struct which provides common fields
+- The database uses a factory pattern for model access
+
+## File Structure
+
+Create a new file in `lib/hero/heromodels/` with the model name (e.g., `calendar.v`).
+
+## Required Components
+
+### 1. Model Struct Definition
+
+Define your model struct with the following pattern:
+
+```v
+@[heap]
+pub struct Calendar {
+ db.Base // Inherit from Base struct
+pub mut:
+ // Add your specific fields here
+ title string
+ start_time i64
+ end_time i64
+ location string
+ attendees []string
+}
+```
+
+### 2. Type Name Method
+
+Implement a method to return the model's type name:
+
+```v
+pub fn (self Calendar) type_name() string {
+ return 'calendar'
+}
+```
+
+### 3. Serialization (dump) Method
+
+Implement the `dump` method to serialize your struct's fields using the encoder:
+
+```v
+pub fn (self Calendar) dump(mut e &encoder.Encoder) ! {
+ e.add_string(self.title)
+ e.add_i64(self.start_time)
+ e.add_i64(self.end_time)
+ e.add_string(self.location)
+ e.add_list_string(self.attendees)
+}
+```
+
+### 4. Deserialization (load) Method
+
+Implement the `load` method to deserialize your struct's fields:
+
+```v
+fn (mut self DBCalendar) load(mut o Calendar, mut e &encoder.Decoder) ! {
+ o.title = e.get_string()!
+ o.start_time = e.get_i64()!
+ o.end_time = e.get_i64()!
+ o.location = e.get_string()!
+ o.attendees = e.get_list_string()!
+}
+```
+
+### 5. Model Arguments Struct
+
+Define a struct for creating new instances of your model:
+
+```v
+@[params]
+pub struct CalendarArg {
+pub mut:
+ title string @[required]
+ start_time i64
+ end_time i64
+ location string
+ attendees []string
+}
+```
+
+### 6. Database Wrapper Struct
+
+Create a database wrapper struct for your model:
+
+```v
+pub struct DBCalendar {
+pub mut:
+ db &db.DB @[skip; str: skip]
+}
+```
+
+### 7. Factory Integration
+
+Add your model to the ModelsFactory struct in `factory.v`:
+
+```v
+pub struct ModelsFactory {
+pub mut:
+ comments DBCalendar
+ // ... other models
+}
+```
+
+And initialize it in the `new()` function:
+
+```v
+pub fn new() !ModelsFactory {
+ mut mydb := db.new()!
+ return ModelsFactory{
+ comments: DBCalendar{
+ db: &mydb
+ }
+ // ... initialize other models
+ }
+}
+```
+
+## Encoder Methods Reference
+
+Use these methods for serialization/deserialization:
+
+### Encoder (Serialization)
+- `e.add_bool(val bool)`
+- `e.add_u8(val u8)`
+- `e.add_u16(val u16)`
+- `e.add_u32(val u32)`
+- `e.add_u64(val u64)`
+- `e.add_i8(val i8)`
+- `e.add_i16(val i16)`
+- `e.add_i32(val i32)`
+- `e.add_i64(val i64)`
+- `e.add_f32(val f32)`
+- `e.add_f64(val f64)`
+- `e.add_string(val string)`
+- `e.add_list_bool(val []bool)`
+- `e.add_list_u8(val []u8)`
+- `e.add_list_u16(val []u16)`
+- `e.add_list_u32(val []u32)`
+- `e.add_list_u64(val []u64)`
+- `e.add_list_i8(val []i8)`
+- `e.add_list_i16(val []i16)`
+- `e.add_list_i32(val []i32)`
+- `e.add_list_i64(val []i64)`
+- `e.add_list_f32(val []f32)`
+- `e.add_list_f64(val []f64)`
+- `e.add_list_string(val []string)`
+
+### Decoder (Deserialization)
+- `e.get_bool()!`
+- `e.get_u8()!`
+- `e.get_u16()!`
+- `e.get_u32()!`
+- `e.get_u64()!`
+- `e.get_i8()!`
+- `e.get_i16()!`
+- `e.get_i32()!`
+- `e.get_i64()!`
+- `e.get_f32()!`
+- `e.get_f64()!`
+- `e.get_string()!`
+- `e.get_list_bool()!`
+- `e.get_list_u8()!`
+- `e.get_list_u16()!`
+- `e.get_list_u32()!`
+- `e.get_list_u64()!`
+- `e.get_list_i8()!`
+- `e.get_list_i16()!`
+- `e.get_list_i32()!`
+- `e.get_list_i64()!`
+- `e.get_list_f32()!`
+- `e.get_list_f64()!`
+- `e.get_list_string()!`
+
+## CRUD Methods Implementation
+
+### Create New Instance
+```v
+pub fn (mut self DBCalendar) new(args CalendarArg) !Calendar {
+ mut o := Calendar{
+ title: args.title
+ start_time: args.start_time
+ end_time: args.end_time
+ location: args.location
+ attendees: args.attendees
+ updated_at: ourtime.now().unix()
+ }
+ return o
+}
+```
+
+### Save to Database
+```v
+pub fn (mut self DBCalendar) set(o Calendar) !u32 {
+ return self.db.set[Calendar](o)!
+}
+```
+
+### Retrieve from Database
+```v
+pub fn (mut self DBCalendar) get(id u32) !Calendar {
+ mut o, data := self.db.get_data[Calendar](id)!
+ mut e_decoder := encoder.decoder_new(data)
+ self.load(mut o, mut e_decoder)!
+ return o
+}
+```
+
+### Delete from Database
+```v
+pub fn (mut self DBCalendar) delete(id u32) ! {
+ self.db.delete[Calendar](id)!
+}
+```
+
+### Check Existence
+```v
+pub fn (mut self DBCalendar) exist(id u32) !bool {
+ return self.db.exists[Calendar](id)!
+}
+```
+
+### List All Objects
+```v
+pub fn (mut self DBCalendar) list() ![]Calendar {
+ return self.db.list[Calendar]()!.map(self.get(it)!)
+}
+```
+
+## Example Usage Script
+
+Create a `.vsh` script in `examples/hero/heromodels/` to demonstrate usage:
+
+```v
+#!/usr/bin/env -S v -n -w -cg -gc none -cc tcc -d use_openssl -enable-globals run
+
+import freeflowuniverse.herolib.core.redisclient
+import freeflowuniverse.herolib.hero.heromodels
+
+mut mydb := heromodels.new()!
+
+// Create a new object
+mut o := mydb.calendar.new(
+ title: 'Meeting'
+ start_time: 1672531200
+ end_time: 1672534800
+ location: 'Conference Room'
+ attendees: ['john@example.com', 'jane@example.com']
+)!
+

+
+## Best Practices
+
+1. Always inherit from `db.Base` struct
+2. Implement all required methods (`type_name`, `dump`, `load`)
+3. Use the encoder methods for consistent serialization
+4. Handle errors appropriately with `!` or `or` blocks
+5. Keep field ordering consistent between `dump` and `load` methods
+6. Use snake_case for field names
+7. Add `@[required]` attribute to mandatory fields in argument structs
+8. Initialize timestamps using `ourtime.now().unix()`
+
+## Implementation Steps Summary
+
+1. Create model struct inheriting from `db.Base`
+2. Implement `type_name()` method
+3. Implement `dump()` method using encoder
+4. Implement `load()` method using decoder
+5. Create argument struct with `@[params]` attribute
+6. Create database wrapper struct
+7. Add model to `ModelsFactory` in `factory.v`
+8. Implement CRUD methods
+9. Create example usage script
+10. Test the implementation with the example script

+# HeroScript: Vlang Integration
+
+## HeroScript Structure
+
+HeroScript is a concise scripting language with the following structure:
+
+```heroscript
+!!actor.action_name
+ param1: 'value1'
+ param2: 'value with spaces'
+ multiline_description: '
+ This is a multiline description.
+ It can span multiple lines.
+ '
+ arg1 arg2 // Arguments without keys
+```
+
+Key characteristics:
+- **Actions**: Start with `!!`, followed by `actor.action_name` (e.g., `!!mailclient.configure`).
+- **Parameters**: Defined as `key:value`. Values can be quoted for spaces.
+- **Multiline Support**: Parameters like `description` can span multiple lines.
+- **Arguments**: Values without keys (e.g., `arg1`).
+
+## Processing HeroScript in Vlang
+
+HeroScript can be parsed into a `playbook.PlayBook` object, allowing structured access to actions and their parameters, this is used in most of the herolib modules, it allows configuration or actions in a structured way.
+
+```v
+import freeflowuniverse.herolib.core.playbook { PlayBook }
+import freeflowuniverse.herolib.ui.console
+
+pub fn play(mut plbook PlayBook) ! {
+
+ if plbook.exists_once(filter: 'docusaurus.define') {
+ mut action := plbook.get(filter: 'docusaurus.define')!
+ mut p := action.params
+ //example how we get parameters from the action see core_params.md for more details
+ ds = new(
+ path: p.get_default('path_publish', '')!
+ production: p.get_default_false('production')
+ )!
+ }
+
+ // Process 'docusaurus.add' actions to configure individual Docusaurus sites
+ actions := plbook.find(filter: 'docusaurus.add')!
+ for action in actions {
+ mut p := action.params
+ //do more processing here
+ }
+}
+```
+
+For detailed information on parameter retrieval methods (e.g., `p.get()`, `p.get_int()`, `p.get_default_true()`), refer to `aiprompts/ai_core/core_params.md`.
+
+
+```

+# PlayBook
+
+## get & execute a playbook

+# HTTPConnection Module
+
+The `HTTPConnection` module provides a robust HTTP client for Vlang, supporting JSON, custom headers, retries, and caching.
+
+## Key Features
+- Type-safe JSON methods
+- Custom headers
+- Retry mechanism
+- Caching
+- URL encoding
+
+## Basic Usage
+
+```v
+import freeflowuniverse.herolib.core.httpconnection
+
+// Create a new HTTP connection
+mut conn := httpconnection.new(
+ name: 'my_api_client'
+ url: 'https://api.example.com'
+ retry: 3 // Number of retries for failed requests
+ cache: true // Enable caching
+)!
+```
+
+## Integration with Management Classes
+
+To integrate `HTTPConnection` into a management class (e.g., `HetznerManager`), use a method to lazily initialize and return the connection:
+
+```v
+// Example: HetznerManager
+pub fn (mut h HetznerManager) connection() !&httpconnection.HTTPConnection {
+ mut c := h.conn or {
+ mut c2 := httpconnection.new(
+ name: 'hetzner_${h.name}'
+ url: h.baseurl
+ cache: true
+ retry: 3
+ )!
+ c2.basic_auth(h.user, h.password)
+ c2
+ }
+ return c
+}
+```
+
+## Examples
+
+### GET Request with JSON Response
+
+```v
+struct User {
+ id int
+ name string
+ email string
+}
+
+user := conn.get_json_generic[User](
+ prefix: 'users/1'
+)!
+```
+
+### POST Request with JSON Data
+
+```v
+struct NewUserResponse {
+ id int
+ status string
+}
+
+new_user_resp := conn.post_json_generic[NewUserResponse](
+ prefix: 'users'
+ params: {
+ 'name': 'Jane Doe'
+ 'email': 'jane@example.com'
+ }
+)!
+```
+
+### Custom Headers
+
+Set default headers or add them per request:
+
+```v
+import net.http { Header }
+
+// Set default header
+conn.default_header = http.new_header(key: .authorization, value: 'Bearer your-token')
+
+// Add custom header for a specific request
+response := conn.get_json(
+ prefix: 'protected/resource'
+ header: http.new_header(key: .content_type, value: 'application/json')
+)!
+```
+
+### Error Handling
+
+Methods return a `Result` type for error handling:
+
+```v
+user := conn.get_json_generic[User](
+ prefix: 'users/1'
+) or {
+ println('Error fetching user: ${err}')
+ return
+}
+

+```md
+# OurTime Module
+
+The `OurTime` module in V provides flexible time handling, supporting relative and absolute time formats, Unix timestamps, and formatting utilities.
+
+## Key Features
+- Create time objects from strings or current time
+- Relative time expressions (e.g., `+1h`, `-2d`)
+- Absolute time formats (e.g., `YYYY-MM-DD HH:mm:ss`)
+- Unix timestamp conversion
+- Time formatting and warping
+
+## Basic Usage
+
+```v
+import freeflowuniverse.herolib.data.ourtime
+
+// Current time
+mut t := ourtime.now()
+
+// From string
+t2 := ourtime.new('2022-12-05 20:14:35')!
+
+// Get formatted string
+println(t2.str()) // e.g., 2022-12-05 20:14
+
+// Get Unix timestamp
+println(t2.unix()) // e.g., 1670271275
+```
+
+## Time Formats
+
+### Relative Time
+
+Use `s` (seconds), `h` (hours), `d` (days), `w` (weeks), `M` (months), `Q` (quarters), `Y` (years).
+
+```v
+// Create with relative time
+mut t := ourtime.new('+1w +2d -4h')!
+
+// Warp existing time
+mut t2 := ourtime.now()
+t2.warp('+1h')!
+```
+
+### Absolute Time
+
+Supports `YYYY-MM-DD HH:mm:ss`, `YYYY-MM-DD HH:mm`, `YYYY-MM-DD HH`, `YYYY-MM-DD`, `DD-MM-YYYY`.
+
+```v
+t1 := ourtime.new('2022-12-05 20:14:35')!
+t2 := ourtime.new('2022-12-05')! // Time defaults to 00:00:00
+```
+
+## Methods Overview
+
+### Creation
+
+```v
+now_time := ourtime.now()
+from_string := ourtime.new('2023-01-15')!
+from_epoch := ourtime.new_from_epoch(1673788800)
+```
+
+### Formatting
+
+```v
+mut t := ourtime.now()
+println(t.str()) // YYYY-MM-DD HH:mm
+println(t.day()) // YYYY-MM-DD
+println(t.key()) // YYYY_MM_DD_HH_mm_ss
+println(t.md()) // Markdown format
+```
+
+### Operations
+
+```v
+mut t := ourtime.now()
+t.warp('+1h')! // Move 1 hour forward
+unix_ts := t.unix()
+is_empty := t.empty()
+```
+
+## Error Handling
+
+Time parsing methods return a `Result` type and should be handled with `!` or `or` blocks.
+
+```v
+t_valid := ourtime.new('2023-01-01')!
+t_invalid := ourtime.new('bad-date') or {
+ println('Error: ${err}')
+ ourtime.now() // Fallback
+}
+
+```
+
+File: /Users/despiegk/code/github/freeflowuniverse/herolib/aiprompts/herolib_core/core_params.md
+```md
+# Parameter Parsing in Vlang
+
+This document details the `paramsparser` module, essential for handling parameters in HeroScript and other contexts.
+
+## Obtaining a `paramsparser` Instance
+
+```v
+import freeflowuniverse.herolib.data.paramsparser
+
+// Create new params from a string
+params := paramsparser.new("color:red size:'large' priority:1 enable:true")!
+
+// Or create an empty instance and add parameters programmatically
+mut params := paramsparser.new_params()
+params.set("color", "red")
+```
+
+## Parameter Formats
+
+The parser supports various input formats:
+
+1. **Key-value pairs**: `key:value`
+2. **Quoted values**: `key:'value with spaces'` (single or double quotes)
+3. **Arguments without keys**: `arg1 arg2` (accessed by index)
+4. **Comments**: `// this is a comment` (ignored during parsing)
+
+Example:
+```v
+text := "name:'John Doe' age:30 active:true // user details"
+params := paramsparser.new(text)!
+```
+
+## Parameter Retrieval Methods
+
+The `paramsparser` module provides a comprehensive set of methods for retrieving and converting parameter values.
+
+### Basic Retrieval
+
+- `get(key string) !string`: Retrieves a string value by key. Returns an error if the key does not exist.
+- `get_default(key string, defval string) !string`: Retrieves a string value by key, or returns `defval` if the key is not found.
+- `exists(key string) bool`: Checks if a keyword argument (`key:value`) exists.
+- `exists_arg(key string) bool`: Checks if an argument (value without a key) exists.
+
+### Argument Retrieval (Positional)
+
+- `get_arg(nr int) !string`: Retrieves an argument by its 0-based index. Returns an error if the index is out of bounds.
+- `get_arg_default(nr int, defval string) !string`: Retrieves an argument by index, or returns `defval` if the index is out of bounds.
+
+### Type-Specific Retrieval

+# Pathlib Usage Guide
+
+## Overview
+
+The pathlib module provides a comprehensive interface for handling file system operations. Key features include:
+
+- Robust path handling for files, directories, and symlinks
+- Support for both absolute and relative paths
+- Automatic home directory expansion (~)
+- Recursive directory operations
+- Path filtering and listing
+- File and directory metadata access
+
+## Basic Usage
+
+### Importing pathlib
+```v
+import freeflowuniverse.herolib.core.pathlib
+```
+
+### Creating Path Objects
+```v
+// Create a Path object for a file
+mut file_path := pathlib.get("path/to/file.txt")
+
+// Create a Path object for a directory
+mut dir_path := pathlib.get("path/to/directory")
+```
+
+### Basic Path Operations
+```v
+// Get absolute path
+abs_path := file_path.absolute()
+
+// Get real path (resolves symlinks)
+real_path := file_path.realpath()
+
+// Check if path exists
+if file_path.exists() {
+ // Path exists
+}
+```
+
+## Path Properties and Methods
+
+### Path Types
+```v
+// Check if path is a file
+if file_path.is_file() {
+ // Handle as file
+}
+
+// Check if path is a directory
+if dir_path.is_dir() {
+ // Handle as directory
+}
+
+// Check if path is a symlink
+if file_path.is_link() {
+ // Handle as symlink
+}
+```
+
+### Path Normalization
+```v
+// Normalize path (remove extra slashes, resolve . and ..)
+normalized_path := file_path.path_normalize()
+
+// Get path directory
+dir_path := file_path.path_dir()
+
+// Get path name without extension
+name_no_ext := file_path.name_no_ext()
+```
+
+## File and Directory Operations
+
+### File Operations
+```v
+// Write to file
+file_path.write("Content to write")!
+
+// Read from file
+content := file_path.read()!
+
+// Delete file
+file_path.delete()!
+```
+
+### Directory Operations
+```v
+// Create directory
+mut dir := pathlib.get_dir(
+ path: "path/to/new/dir"
+ create: true
+)!
+
+// List directory contents
+mut dir_list := dir.list()!
+
+// Delete directory
+dir.delete()!
+```
+
+### Symlink Operations
+```v
+// Create symlink
+file_path.link("path/to/symlink", delete_exists: true)!
+
+// Resolve symlink
+real_path := file_path.realpath()
+```
+
+## Advanced Operations
+
+### Path Copying
+```v
+// Copy file to destination
+file_path.copy(dest: "path/to/destination")!
+```
+
+### Recursive Operations
+```v
+// List directory recursively
+mut recursive_list := dir.list(recursive: true)!
+
+// Delete directory recursively
+dir.delete()!
+```
+
+### Path Filtering
+```v
+// List files matching pattern
+mut filtered_list := dir.list(
+ regex: [r".*\.txt$"],
+ recursive: true
+)!
+```
+
+## Best Practices
+
+### Error Handling
+```v
+if file_path.exists() {
+ // Safe to operate
+} else {
+ // Handle missing file
+}
+```
+
+
+```

+# TextTools Module
+
+The `texttools` module provides a comprehensive set of utilities for text manipulation and processing.
+
+## Functions and Examples:
+
+```v
+import freeflowuniverse.herolib.core.texttools
+
+assert hello_world == texttools.name_fix("Hello World!")
+
+```
+### Name/Path Processing
+* `name_fix(name string) string`: Normalizes filenames and paths.
+* `name_fix_keepspace(name string) !string`: Like name_fix but preserves spaces.
+* `name_fix_no_ext(name_ string) string`: Removes file extension.
+* `name_fix_snake_to_pascal(name string) string`: Converts snake_case to PascalCase.
+ ```v
+ name := texttools.name_fix_snake_to_pascal("hello_world") // Result: "HelloWorld"
+ ```
+* `snake_case(name string) string`: Converts PascalCase to snake_case.
+ ```v
+ name := texttools.snake_case("HelloWorld") // Result: "hello_world"
+ ```
+* `name_split(name string) !(string, string)`: Splits name into site and page components.
+
+
+### Text Cleaning
+* `name_clean(r string) string`: Normalizes names by removing special characters.
+ ```v
+ name := texttools.name_clean("Hello@World!") // Result: "HelloWorld"
+ ```
+* `ascii_clean(r string) string`: Removes all non-ASCII characters.
+* `remove_empty_lines(text string) string`: Removes empty lines from text.
+ ```v
+ text := texttools.remove_empty_lines("line1\n\nline2\n\n\nline3") // Result: "line1\nline2\nline3"
+ ```
+* `remove_double_lines(text string) string`: Removes consecutive empty lines.
+* `remove_empty_js_blocks(text string) string`: Removes empty code blocks (```...```).
+
+### Command Line Parsing
+* `cmd_line_args_parser(text string) ![]string`: Parses command line arguments with support for quotes and escaping.
+ ```v
+ args := texttools.cmd_line_args_parser("'arg with spaces' --flag=value") // Result: ['arg with spaces', '--flag=value']
+ ```
+* `text_remove_quotes(text string) string`: Removes quoted sections from text.
+* `check_exists_outside_quotes(text string, items []string) bool`: Checks if items exist in text outside of quotes.
+
+### Text Expansion
+* `expand(txt_ string, l int, expand_with string) string`: Expands text to a specified length with a given character.
+
+### Indentation
+* `indent(text string, prefix string) string`: Adds indentation prefix to each line.
+ ```v
+ text := texttools.indent("line1\nline2", " ") // Result: " line1\n line2\n"
+ ```
+* `dedent(text string) string`: Removes common leading whitespace from every line.
+ ```v
+ text := texttools.dedent(" line1\n line2") // Result: "line1\nline2"
+ ```
+
+### String Validation
+* `is_int(text string) bool`: Checks if text contains only digits.
+* `is_upper_text(text string) bool`: Checks if text contains only uppercase letters.
+
+### Multiline Processing
+* `multiline_to_single(text string) !string`: Converts multiline text to a single line with proper escaping.
+
+### Text Splitting
+* `split_smart(t string, delimiter_ string) []string`: Intelligent string splitting that respects quotes.
+
+### Tokenization
+* `tokenize(text_ string) TokenizerResult`: Tokenizes text into meaningful parts.
+* `text_token_replace(text string, tofind string, replacewith string) !string`: Replaces tokens in text.
+
+### Version Parsing
+* `version(text_ string) int`: Converts version strings to comparable integers.
+ ```v
+ ver := texttools.version("v0.4.36") // Result: 4036
+ ver = texttools.version("v1.4.36") // Result: 1004036
+ ```
+
+### Formatting
+* `format_rfc1123(t time.Time) string`: Formats a time.Time object into RFC 1123 format.
+
+

+ ```v
+ text := "item1,item2,item3"
+ array := texttools.to_array(text) // Result: ['item1', 'item2', 'item3']
+ ```
+* `to_array_int(r string) []int`: Converts a text list to an array of integers.
+* `to_map(mapstring string, line string, delimiter_ string) map[string]string`: Intelligent mapping of a line to a map based on a template.

+ "root 304 0.0 0.0 408185328 1360 ?? S 16Dec23 0:34.06 /usr/sbin/distnoted")
+ // Result: {'name': 'root', 'pid': '1360', 'path': '/usr/sbin/distnoted'}
+ ```

+# Business Models (`biz`)
+
+The `biz` module provides a suite of models for handling core business operations, including company management, product catalogs, sales, payments, and shareholder records.
+
+## Core Models
+
+### `Company`
+
+The `Company` struct is the central model, representing a business entity.
+
+- **Key Fields**: `name`, `registration_number`, `incorporation_date`, `address`, `business_type`, and `status`.
+- **Enums**:
+ - `CompanyStatus`: Tracks the company's state (`PendingPayment`, `Active`, `Suspended`, `Inactive`).
+ - `BusinessType`: Categorizes the company (e.g., `Coop`, `Single`, `Global`).
+- **Functionality**: Provides a foundation for linking other business models like products, sales, and shareholders.
+
+### `Product`
+
+The `Product` model defines goods or services offered by a company.
+
+- **Key Fields**: `name`, `description`, `price`, `category`, `status`, and `components`.
+- **Nested Struct**: `ProductComponent` allows for defining complex products with sub-parts.
+- **Enums**:
+ - `ProductType`: Differentiates between a `Product` and a `Service`.
+ - `ProductStatus`: Indicates if a product is `Available` or `Unavailable`.
+
+### `Sale`
+
+The `Sale` struct records a transaction, linking a buyer to products.
+
+- **Key Fields**: `company_id`, `buyer_id`, `total_amount`, `sale_date`, and `status`.
+- **Nested Struct**: `SaleItem` captures a snapshot of each product at the time of sale, including `product_id`, `quantity`, and `unit_price`.
+- **Enum**: `SaleStatus` tracks the state of the sale (`Pending`, `Completed`, `Cancelled`).
+
+### `Payment`
+
+The `Payment` model handles financial transactions, often linked to sales or subscriptions.
+
+- **Key Fields**: `payment_intent_id` (e.g., for Stripe), `company_id`, `total_amount`, `currency`, and `status`.
+- **Functionality**: Includes methods to manage the payment lifecycle (`process_payment`, `complete_payment`, `fail_payment`, `refund_payment`).
+- **Enum**: `PaymentStatus` provides a detailed state of the payment (`Pending`, `Processing`, `Completed`, `Failed`, `Refunded`).
+
+### `Shareholder`
+
+The `Shareholder` model tracks ownership of a company.
+
+- **Key Fields**: `company_id`, `user_id`, `name`, `shares`, and `percentage`.
+- **Enum**: `ShareholderType` distinguishes between `Individual` and `Corporate` shareholders.
+
+## Workflow Example
+
+1. A `Company` is created.
+2. The company defines several `Product` models representing its offerings.
+3. A customer (buyer) initiates a purchase, which creates a `Sale` record containing multiple `SaleItem`s.
+4. A `Payment` record is generated to process the transaction for the `Sale`'s total amount.
+5. As the company grows, `Shareholder` records are created to track equity distribution.
+
+All models use the builder pattern for easy and readable instance creation.

+You are a senior software architect specializing in code design and implementation planning. Your role is to:
+
+1. Analyze the requested changes and break them down into clear, actionable steps
+2. Create a detailed implementation plan that includes:
+ - Files that need to be modified
+ - Specific code sections requiring changes
+ - New functions, methods, or classes to be added
+ - Dependencies or imports to be updated
+ - Data structure modifications
+ - Interface changes
+ - Configuration updates
+
+For each change:
+- Describe the exact location in the code where changes are needed
+- Explain the logic and reasoning behind each modification
+- Provide example signatures, parameters, and return types
+- Note any potential side effects or impacts on other parts of the codebase
+- Highlight critical architectural decisions that need to be made
+
+You may include short code snippets to illustrate specific patterns, signatures, or structures, but do not implement the full solution.
+
+Focus solely on the technical implementation plan - exclude testing, validation, and deployment considerations unless they directly impact the architecture.
+
+Please proceed with your analysis based on the following
+
+
+

+## INTENT
+
+we use heroscript to communicate actions and events in a structured format.
+we want you to parse user intents and generate the corresponding heroscript.
+
+ONLY RETURN THE HEROSCRIPT STATEMENTS, can be more than 1
+
+## HEROSCRIPT FORMAT
+
+HeroScript is a concise scripting language with the following structure:
+
+```heroscript
+!!actor.action_name
+ param1: 'value1'
+ param2: 'value with spaces'
+ multiline_description: '
+ This is a multiline description.
+ It can span multiple lines.
+ '
+ arg1 arg2 // Arguments without keys
+
+!!actor.action_name2 param1:something param2:'something with spaces' nr:3
+```
+
+Key characteristics:
+
+- **Actions**: Start with `!!`, followed by `actor.action_name` (e.g., `!!mailclient.configure`).
+- **Parameters**: Defined as `key:value`. Values can be quoted for spaces.
+- **Multiline Support**: Parameters like `description` can span multiple lines.
+- **Arguments**: Values without keys (e.g., `arg1`).
+- params can be on 1 line, with spaces in between
+- time can be as +1h, +1d, +1w (hour, day, week), ofcourse 1 can be any number, +1 means 1 hour from now
+- time format is: dd/mm/yyyy hh:mm (ONLY USE THIS)
+- comma separation is used a lot in arguments e.g. 'jan,kristof' or 'jan , kristof' remove spaces, is list of 2
+- note only !! is at start of line, rest has spaces per instruction
+- make one empty line between 1 heroscript statements
+- everything after // is comment
+
+## HEROSCRIPT SCHEMA
+
+the language we understand
+
+### calendar management
+
+```heroscript
+!!calendar.create when:'+1h' descr:'this is event to discuss eng' attendees:'jan,kristof' name:'meet1' tags:'eng,urgent'
+!!calendar.delete name:'meet1'
+!!calendar.list tags:'urgent'
+
+```
+
+### contact management
+
+```heroscript
+!!contact.add name:'jan' email:'jan@example.com' phone:'123-456-7890'
+!!contact.remove name:'jan'
+!!contact.list
+
+```
+
+### task management
+
+```heroscript
+!!task.create title:'Prepare presentation' due:'+1d' assignee:'jan' name:'task1' tags:'eng,urgent'
+ deadline:'+10d' duration:'1h'
+!!task.update name:'task1' status:'in progress'
+!!task.delete name:'task1'
+!!task.list
+
+```
+
+### project management
+
+```heroscript
+!!project.create title:'Cloud Product Development' description:'Track progress of cloud product development' name:'cloud_prod'
+!!project.update name:'cloud_prod' status:'in progress'
+!!project.delete name:'cloud_prod'
+!!project.list
+!!project.tasks_list name:'cloud_prod' //required properties are name, description, and assignee of not given ask
+!!project.tasks_add names:'task1, task2'
+!!project.tasks_remove names:'task1, task2'
+
+```
+
+### SUPPORTED TAGS
+
+only tags supported are:
+
+- for intent: eng, prod, support, mgmt, marketing
+- for urgency: urgent, high, medium, low
+
+### generic remarks
+
+- names are lowercase and snake_case, can be distilled out of title if only title given, often a user will say name but that means title
+- time: format of returned data or time is always dd/mm/yyyy hh:min
+
+## IMPORTANT STARTING INFO
+
+- current time is 10/08/2025 05:10 , use this to define any time-related parameters
+
+## USER INTENT
+
+I want a meeting tomorrow 10am, where we will discuss our new product for the cloud with jan and alex, and the urgency is high
+
+also let me know which other meetings I have which are urgent
+
+can you make a project where we can track the progress of our new product development? Name is 'Cloud Product Development'
+
+Please add tasks to the project in line to creating specifications, design documents, and implementation plans.

+SYSTEM
+You are a HeroScript compiler. Convert user intents into valid HeroScript statements.
+
+OUTPUT RULES
+
+1) Return ONLY HeroScript statements. No prose, no backticks.
+2) Separate each statement with exactly ONE blank line.
+3) Keys use snake_case. Names are lowercase snake_case derived from titles (non-alnum → "_", collapse repeats, trim).
+4) Lists are comma-separated with NO spaces (e.g., "jan,alex").
+5) Times: OUTPUT MUST BE ABSOLUTE in "dd/mm/yyyy hh:mm" (Europe/Zurich). Convert relative times (e.g., "tomorrow 10am") using CURRENT_TIME.
+6) Tags: include at most one intent tag and at most one urgency tag when present.
+ - intent: eng,prod,support,mgmt,marketing
+ - urgency: urgent,high,medium,low
+7) Quotes: quote values containing spaces; otherwise omit quotes (allowed either way).
+8) Comments only with // if the user explicitly asks for explanations; otherwise omit.
+
+SCHEMA (exact actions & parameters)
+
+!!calendar.create when:'dd/mm/yyyy hh:mm' name:'' descr:'' attendees:'a,b,c' tags:'intent,urgency'
+!!calendar.delete name:''
+!!calendar.list [tags:'tag1,tag2']
+
+!!contact.add name:'' email:'' phone:''
+!!contact.remove name:''
+!!contact.list
+
+!!task.create title:'' name:'' [due:'dd/mm/yyyy hh:mm'] [assignee:''] [tags:'intent,urgency'] [deadline:'dd/mm/yyyy hh:mm'] [duration:' or ']
+!!task.update name:'' [status:'in progress|done|blocked|todo']

+!!task.list
+
+!!project.create title:'' description:'' name:''
+!!project.update name:'' [status:'in progress|done|blocked|todo']

+!!project.list
+!!project.tasks_list name:''
+!!project.tasks_add name:'' names:'task_a,task_b'
+!!project.tasks_remove name:'' names:'task_a,task_b'
+
+NORMALIZATION & INFERENCE (silent)
+- Derive names from titles when missing (see rule 3). Ensure consistency across statements.
+- Map phrases to tags when obvious (e.g., "new product" ⇒ intent: prod; "high priority" ⇒ urgency: high).
+- Attendees: split on commas, trim, lowercase given names.
+- If the user asks for “urgent meetings,” use tags:'urgent' specifically.
+- Prefer concise descriptions pulled from the user’s phrasing.
+- Name's are required, if missing ask for clarification.
+- For calendar management, ensure to include all relevant details such as time, attendees, and description.

+## INSTRUCTIONS
+
+the user will send me multiple instructions what they wants to do, I want you to put them in separate categories
+
+The categories we have defined are:
+
+- calendar management
+ - schedule meetings, events, reminders
+ - list these events
+ - delete them
+- contact management
+ - add/remove contact information e.g. phone numbers, email addresses, address information
+ - list contacts, search
+- task or project management
+ - anything we need to do, anything we need to track and plan
+ - create/update tasks, set deadlines
+ - mark tasks as complete
+ - delete tasks
+ - project management
+- communication (chat, email)
+ - see what needs to be communicate e.g. send a chat to ...
+- search statements
+ - find on internet, find specific information from my friends
+
+I want you to detect the intent and make multiple blocks out of the intent, each block should correspond to one of the identified intents, identify the intent with name of the category eg. calendar, only use above names
+
+
+
+what user wants to do, stay as close as possible to the original instructions, copy the exact instructions as where given by the user, we only need to sort the instructions in these blocks
+
+for each instruction make a separate block, e.g. if 2 tasks are given, create 2 blocks
+
+the format to return is: (note newline after each title of block)
+
+```template
+===CALENDAR===\n
+
+$the copied text from what user wants
+
+===CONTACT===\n
+...
+
+===QUESTION===\n
+
+put here what our system needs to ask to the user anything which is not clear
+
+===END===\n
+
+```
+
+I want you to execute above on instructions as given by user below, give text back ONLY supporting the template
+
+note for format is only ===$NAME=== and then on next lines the original instructions from the user, don't change
+
+## special processing of info
+
+- if a date or time specified e.g. tomorrow, time, ... calculate back from current date
+
+## IMPORTANT STARTING INFO
+
+- current time is 10/08/2025 05:10 (format of returned data is always dd/mm/yyyy hh:min)
+ - use the current time to define formatted time out of instructions
+ - only return the formatted time
+
+## UNCLEAR INFO
+
+check in instructions e.g. things specified like you, me, ...
+are not clear ask specifically who do you mean
+
+if task, specify per task, who needs to do it and when, make sure each instruction (block) is complete and clear for further processing
+
+be very specific with the questions e.g. who is you, ...
+
+## EXECUTE ABOVE ON THE FOLLOWING
+
+I am planning a birthday for my daughters tomorrow, there will be 10 people.
+
+I would like to know if you can help me with the preparations.
+
+I need a place for my daughter's birthday party.
+
+I need to send message to my wife isabelle that she needs to pick up the cake.

+## `crypto.blake3` Module
+
+
+```v
+fn sum256(data []u8) []u8
+```
+
+Returns the Blake3 256-bit hash of the provided data.
+
+```v
+fn sum_derive_key256(context []u8, key_material []u8) []u8
+```
+
+Computes the Blake3 256-bit derived-key hash based on the context and key material.
+
+```v
+fn sum_keyed256(data []u8, key []u8) []u8
+```
+
+Returns the Blake3 256-bit keyed hash of the data using the specified key.
+
+---
+
+### Digest-Based API
+
+```v
+fn Digest.new_derive_key_hash(context []u8) !Digest
+```
+
+Initializes a `Digest` struct for creating a Blake3 derived‑key hash, using the provided context.
+
+```v
+fn Digest.new_hash() !Digest
+```
+
+Initializes a `Digest` struct for a standard (unkeyed) Blake3 hash.
+
+```v
+fn Digest.new_keyed_hash(key []u8) !Digest
+```
+
+Initializes a `Digest` struct for a keyed Blake3 hash, with the given key.
+
+---
+
+### `Digest` Methods
+
+```v
+fn (mut d Digest) write(data []u8) !
+```
+
+Feeds additional data bytes into the ongoing hash computation.
+
+```v
+fn (mut d Digest) checksum(size u64) []u8
+```
+
+Finalizes the hash and returns the resulting output.
+
+* The `size` parameter specifies the number of output bytes—commonly `32` for a 256-bit digest, but can be up to `2**64`.
+
+---
+
+### Recommended Usage (in V)
+
+```v
+import crypto.blake3
+
+mut hasher := crypto.blake3.Digest.new_hash() or { panic(err) }
+hasher.write(data) or { panic(err) }
+digest := hasher.checksum(24) // returns a []u8 of length 24 (192 bits)

+## append
+```v
+fn append[T](a []T, b []T) []T
+```
+
+append the second array `b` to the first array `a`, and return the result. Note, that unlike arrays.concat, arrays.append is less flexible, but more efficient, since it does not require you to use ...a for the second parameter.
+
+Example
+```v
+
+arrays.append([1, 3, 5, 7], [2, 4, 6, 8]) // => [1, 3, 5, 7, 2, 4, 6, 8]
+
+```
+
+[[Return to contents]](#Contents)
+
+## binary_search
+```v
+fn binary_search[T](array []T, target T) !int
+```
+
+binary_search, requires `array` to be sorted, returns index of found item or error. Binary searches on sorted lists can be faster than other array searches because at maximum the algorithm only has to traverse log N elements
+
+Example
+```v
+
+arrays.binary_search([1, 2, 3, 4], 4)! // => 3
+
+```
+
+[[Return to contents]](#Contents)
+
+## carray_to_varray
+```v
+fn carray_to_varray[T](c_array_data voidptr, items int) []T
+```
+
+carray_to_varray copies a C byte array into a V array of type `T`. See also: `cstring_to_vstring`
+
+[[Return to contents]](#Contents)
+
+## chunk
+```v
+fn chunk[T](array []T, size int) [][]T
+```
+
+chunk array into a single array of arrays where each element is the next `size` elements of the original.
+
+Example
+```v
+
+arrays.chunk([1, 2, 3, 4, 5, 6, 7, 8, 9], 2) // => [[1, 2], [3, 4], [5, 6], [7, 8], [9]]
+
+```
+
+[[Return to contents]](#Contents)
+
+## chunk_while
+```v
+fn chunk_while[T](a []T, predicate fn (before T, after T) bool) [][]T
+```
+
+chunk_while splits the input array `a` into chunks of varying length, using the `predicate`, passing to it pairs of adjacent elements `before` and `after`. Each chunk, will contain all ajdacent elements, for which the `predicate` returned true. The chunks are split *between* the `before` and `after` elements, for which the `predicate` returned false.
+
+Examples
+```v
+
+assert arrays.chunk_while([0,9,2,2,3,2,7,5,9,5],fn(x int,y int)bool{return x<=y})==[[0,9],[2,2,3],[2,7],[5,9],[5]]
+
+assert arrays.chunk_while('aaaabbbcca'.runes(),fn(x rune,y rune)bool{return x==y})==[[`a`,`a`,`a`,`a`],[`b`,`b`,`b`],[`c`,`c`],[`a`]]
+
+assert arrays.chunk_while('aaaabbbcca'.runes(),fn(x rune,y rune)bool{return x==y}).map({it[0]:it.len})==[{`a`:4},{`b`:3},{`c`:2},{`a`:1}]

+[[Return to contents]](#Contents)
+
+## concat
+```v
+fn concat[T](a []T, b ...T) []T
+```
+
+concatenate an array with an arbitrary number of additional values.
+
+Note: if you have two arrays, you should simply use the `<<` operator directly.
+
+Examples
+```v
+
+assert arrays.concat([1, 2, 3], 4, 5, 6) == [1, 2, 3, 4, 5, 6]
+
+assert arrays.concat([1, 2, 3], ...[4, 5, 6]) == [1, 2, 3, 4, 5, 6]
+
+mut arr := arrays.concat([1, 2, 3], 4); arr << [10,20]; assert arr == [1,2,3,4,10,20] // note: arr is mutable
+
+```
+
+[[Return to contents]](#Contents)
+
+## copy
+```v
+fn copy[T](mut dst []T, src []T) int

+[[Return to contents]](#Contents)
+
+## distinct
+```v
+fn distinct[T](a []T) []T
+```
+
+distinct returns all distinct elements from the given array a. The results are guaranteed to be unique, i.e. not have duplicates. See also arrays.uniq, which can be used to achieve the same goal, but needs you to first sort the array.
+
+Example
+```v
+
+assert arrays.distinct( [5, 5, 1, 5, 2, 1, 1, 9] ) == [1, 2, 5, 9]
+
+```
+
+[[Return to contents]](#Contents)
+
+## each
+```v
+fn each[T](a []T, cb fn (elem T))
+```
+
+each calls the callback fn `cb`, for each element of the given array `a`.
+
+[[Return to contents]](#Contents)
+
+## each_indexed
+```v
+fn each_indexed[T](a []T, cb fn (i int, e T))
+```
+
+each_indexed calls the callback fn `cb`, for each element of the given array `a`. It passes the callback both the index of the current element, and the element itself.

+
+## find_last
+```v
+fn find_last[T](array []T, predicate fn (elem T) bool) ?T

+
+[[Return to contents]](#Contents)
+
+## flatten
+```v
+fn flatten[T](array [][]T) []T
+```
+
+flatten flattens n + 1 dimensional array into n dimensional array.

+
+## fold
+```v
+fn fold[T, R](array []T, init R, fold_op fn (acc R, elem T) R) R
+```
+
+fold sets `acc = init`, then successively calls `acc = fold_op(acc, elem)` for each element in `array`. returns `acc`.

+
+[[Return to contents]](#Contents)
+
+## group
+```v
+fn group[T](arrs ...[]T) [][]T
+```
+
+group n arrays into a single array of arrays with n elements. This function is analogous to the "zip" function of other languages. To fully interleave two arrays, follow this function with a call to `flatten`.
+
+Note: An error will be generated if the type annotation is omitted.
+
+Example
+```v
+
+arrays.group[int]([1, 2, 3], [4, 5, 6]) // => [[1, 4], [2, 5], [3, 6]]
+
+```
+

+```v
+fn index_of_first[T](array []T, predicate fn (idx int, elem T) bool) int
+```
+
+index_of_first returns the index of the first element of `array`, for which the predicate fn returns true. If predicate does not return true for any of the elements, then index_of_first will return -1.
+
+Example
+```v

+[[Return to contents]](#Contents)
+
+## rotate_left
+```v
+fn rotate_left[T](mut array []T, mid int)
+```
+
+rotate_left rotates the array in-place. It does it in such a way, that the first `mid` elements of the array, move to the end, while the last `array.len - mid` elements move to the front. After calling `rotate_left`, the element previously at index `mid` will become the first element in the array.

+
+```
+
+[[Return to contents]](#Contents)
+
+## rotate_right
+```v
+fn rotate_right[T](mut array []T, k int)
+```
+
+rotate_right rotates the array in-place. It does it in such a way, that the first `array.len - k` elements of the array, move to the end, while the last `k` elements move to the front. After calling `rotate_right`, the element previously at index `array.len - k` will become the first element in the array.
+
+Example
+```v
+
+mut x := [1,2,3,4,5,6]
+arrays.rotate_right(mut x, 2)
+println(x) // [5, 6, 1, 2, 3, 4]
+
+```

+[[Return to contents]](#Contents)
+
+## sum
+```v
+fn sum[T](array []T) !T
+```
+
+sum up array, return an error, when the array has no elements.
+
+Example
+```v
+
+arrays.sum([1, 2, 3, 4, 5])! // => 15
+
+```

+
+## uniq
+```v
+fn uniq[T](a []T) []T
+```
+
+uniq filters the adjacent matching elements from the given array. All adjacent matching elements, are merged to their first occurrence, so the output will have no repeating elements.
+
+Note: `uniq` does not detect repeats, unless they are adjacent. You may want to call a.sorted() on your array, before passing the result to arrays.uniq(). See also arrays.distinct, which is essentially arrays.uniq(a.sorted()) .
+
+Examples
+```v
+
+assert arrays.uniq( []int{} ) == []
+
+assert arrays.uniq( [1, 1] ) == [1]
+
+assert arrays.uniq( [2, 1] ) == [2, 1]
+
+assert arrays.uniq( [5, 5, 1, 5, 2, 1, 1, 9] ) == [5, 1, 5, 2, 1, 9]
+
+```
+
+[[Return to contents]](#Contents)
+
+## uniq_all_repeated
+```v
+fn uniq_all_repeated[T](a []T) []T
+```
+
+uniq_all_repeated produces all adjacent matching elements from the given array. Unique elements, with no duplicates are removed. The output will contain all the duplicated elements, repeated just like they were in the original.
+
+Note: `uniq_all_repeated` does not detect repeats, unless they are adjacent. You may want to call a.sorted() on your array, before passing the result to arrays.uniq_all_repeated().
+
+Examples
+```v
+
+assert arrays.uniq_all_repeated( []int{} ) == []
+
+assert arrays.uniq_all_repeated( [1, 5] ) == []
+
+assert arrays.uniq_all_repeated( [5, 5] ) == [5,5]
+
+assert arrays.uniq_all_repeated( [5, 5, 1, 5, 2, 1, 1, 9] ) == [5, 5, 1, 1]
+
+```
+
+[[Return to contents]](#Contents)
+
+## uniq_only
+```v
+fn uniq_only[T](a []T) []T
+```
+
+uniq_only filters the adjacent matching elements from the given array. All adjacent matching elements, are removed. The output will contain only the elements that *did not have* any adjacent matches.
+
+Note: `uniq_only` does not detect repeats, unless they are adjacent. You may want to call a.sorted() on your array, before passing the result to arrays.uniq_only().
+
+Examples
+```v
+
+assert arrays.uniq_only( []int{} ) == []
+
+assert arrays.uniq_only( [1, 1] ) == []
+
+assert arrays.uniq_only( [2, 1] ) == [2, 1]
+
+assert arrays.uniq_only( [1, 5, 5, 1, 5, 2, 1, 1, 9] ) == [1, 1, 5, 2, 9]
+
+```
+
+[[Return to contents]](#Contents)
+
+## uniq_only_repeated
+```v
+fn uniq_only_repeated[T](a []T) []T
+```
+
+uniq_only_repeated produces the adjacent matching elements from the given array. Unique elements, with no duplicates are removed. Adjacent matching elements, are reduced to just 1 element per repeat group.
+
+Note: `uniq_only_repeated` does not detect repeats, unless they are adjacent. You may want to call a.sorted() on your array, before passing the result to arrays.uniq_only_repeated().
+
+Examples
+```v
+
+assert arrays.uniq_only_repeated( []int{} ) == []
+
+assert arrays.uniq_only_repeated( [1, 5] ) == []
+
+assert arrays.uniq_only_repeated( [5, 5] ) == [5]
+
+assert arrays.uniq_only_repeated( [5, 5, 1, 5, 2, 1, 1, 9] ) == [5, 1]
+
+```

+
+## upper_bound
+```v
+fn upper_bound[T](array []T, val T) !T
+```
+
+returns the largest element <= val, requires `array` to be sorted.
+
+Example
+```v
+
+arrays.upper_bound([2, 4, 6, 8], 3)! // => 2
+
+```

+- `step` - gap size between each snapshot, default is 1.
+
+
+
+Examples
+```v
+
+arrays.window([1, 2, 3, 4], size: 2) // => [[1, 2], [2, 3], [3, 4]]
+
+arrays.window([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], size: 3, step: 2) // => [[1, 2, 3], [3, 4, 5], [5, 6, 7], [7, 8, 9]]

+[[Return to contents]](#Contents)
+
+## ReverseIterator[T]
+## next
+```v
+fn (mut iter ReverseIterator[T]) next() ?&T
+```
+
+next is the required method, to implement an iterator in V. It returns none when the iteration should stop. Otherwise it returns the current element of the array.
+
+[[Return to contents]](#Contents)
+
+## free
+```v
+fn (iter &ReverseIterator[T]) free()

+
+amap lets the user run an array of input with a user provided function in parallel. It limits the number of worker threads to max number of cpus. The worker function can return a value. The returning array maintains the input order. Any error handling should have happened within the worker function.
+
+Example
+```v

+[[Return to contents]](#Contents)
+
+## record_measure
+```v
+fn (mut b Benchmark) record_measure(label string) i64
+```
+
+record_measure stores the current time doing `label`, since the benchmark was started, or since the last call to `b.record_measure`. It is similar to `b.measure`, but unlike it, will not print the measurement immediately, just record it for later. You can call `b.all_recorded_measures` to retrieve all measures stored by `b.record_measure` calls.

+-9223372036854775808 is wrong, because C compilers parse literal values without sign first, and 9223372036854775808 overflows i64, hence the consecutive subtraction by 1

+
+## arguments
+```v
+fn arguments() []string
+```
+
+arguments returns the command line arguments, used for starting the current program as a V array of strings. The first string in the array (index 0), is the name of the program, used for invoking the program. The second string in the array (index 1), if it exists, is the first argument to the program, etc. For example, if you started your program as `myprogram -option`, then arguments() will return ['myprogram', '-option'].
+
+Note: if you `v run file.v abc def`, then arguments() will return ['file', 'abc', 'def'], or ['file.exe', 'abc', 'def'] (on Windows).

+
+## at_exit
+```v
+fn at_exit(cb FnExitCb) !
+```
+
+at_exit registers a fn callback, that will be called at normal process termination. It returns an error, if the registration was not successful. The registered callback functions, will be called either via exit/1, or via return from the main program, in the reverse order of their registration. The same fn may be registered multiple times. Each callback fn will called once for each registration.

+
+[[Return to contents]](#Contents)
+
+## compare_strings
+```v
+fn compare_strings(a &string, b &string) int
+```
+
+compare_strings returns `-1` if `a < b`, `1` if `a > b` else `0`.
+
+[[Return to contents]](#Contents)
+
+## copy
+```v
+fn copy(mut dst []u8, src []u8) int
+```
+
+copy copies the `src` byte array elements to the `dst` byte array. The number of the elements copied is the minimum of the length of both arrays. Returns the number of elements copied.
+
+Note: This is not an `array` method. It is a function that takes two arrays of bytes. See also: `arrays.copy`.

+[[Return to contents]](#Contents)
+
+## cstring_to_vstring
+```v
+fn cstring_to_vstring(const_s &char) string
+```
+
+cstring_to_vstring creates a new V string copy of the C style string, pointed by `s`. This function is most likely what you want to use when working with C style pointers to 0 terminated strings (i.e. `char*`). It is recommended to use it, unless you *do* understand the implications of tos/tos2/tos3/tos4/tos5 in terms of memory management and interactions with -autofree and `@[manualfree]`. It will panic, if the pointer `s` is 0.

+```v
+
+f := fn (ouch bool) ! { if ouch { return error('an error occurred') } }; f(false)!
+
+```
+
+[[Return to contents]](#Contents)
+
+## error_with_code
+```v
+fn error_with_code(message string, code int) IError
+```
+
+error_with_code returns a default error instance containing the given `message` and error `code`.
+
+Example
+```v
+
+f := fn (ouch bool) ! { if ouch { return error_with_code('an error occurred', 1) } }; f(false)!

+
+[[Return to contents]](#Contents)
+
+## gc_collect
+```v
+fn gc_collect()
+```

+
+[[Return to contents]](#Contents)
+
+## gc_enable
+```v
+fn gc_enable()

+## reuse_data_as_string
+```v
+fn reuse_data_as_string(buffer []u8) string
+```
+
+reuse_data_as_string provides a way to treat the memory of a []u8 `buffer` as a string value. It does not allocate or copy the memory block for the `buffer`, but instead creates a string descriptor, that will point to the same memory as the input. The intended use of that function, is to allow calling string search methods (defined on string), on []u8 values too, without having to copy/allocate by calling .bytestr() (that can be too slow and unnecessary in loops).
+
+Note: unlike normal V strings, the return value *is not* guaranteed to have a terminating `0` byte, since this function does not allocate or modify the input in any way. This is not a problem usually, since V methods and functions do not require it, but be careful, if you want to pass that string to call a C. function, that expects 0 termination. If you have to do it, make a `tmp := s.clone()` beforehand, and free the cloned `tmp` string after you have called the C. function with it. The .len field of the result value, will be the same as the buffer.len.
+
+Note: avoid storing or returning that resulting string, and avoid calling the fn with a complex expression (prefer using a temporary variable as an argument).

The intended use of that function, is to allow calling array methods (defined on []u8), on string values too, without having to copy/allocate by calling .bytes() (that can be too slow and unnecessary in loops).

+## unbuffer_stdout
+```v
+fn unbuffer_stdout()
+```
+
+unbuffer_stdout will turn off the default buffering done for stdout. It will affect all consequent print and println calls, effectively making them behave like eprint and eprintln do. It is useful for programs, that want to produce progress bars, without cluttering your code with a flush_stdout() call after every print() call. It is also useful for programs (sensors), that produce small chunks of output, that you want to be able to process immediately. Note 1: if used, *it should be called at the start of your program*, before using print or println(). Note 2: most libc implementations, have logic that use line buffering for stdout, when the output stream is connected to an interactive device, like a terminal, and otherwise fully buffer it, which is good for the output performance for programs that can produce a lot of output (like filters, or cat etc), but bad for latency. Normally, it is usually what you want, so it is the default for V programs too. See https://www.gnu.org/software/libc/manual/html_node/Buffering-Concepts.html .

It returns an integer less than, equal to, or greater than zero, if the first n bytes of s1 is found, respectively, to be less than, to match, or be greater than the first n bytes of s2. For a nonzero return value, the sign is determined by the sign of the difference between the first pair of bytes (interpreted as unsigned char) that differ in s1 and s2. If n is zero, the return value is zero. Do NOT use vmemcmp to compare security critical data, such as cryptographic secrets, because the required CPU time depends on the number of equal bytes. You should use a function that performs comparisons in constant time for this.

+## vbytes
+```v
+fn (data &u8) vbytes(len int) []u8

+
+Note: the data is reused, NOT copied!
+
+[[Return to contents]](#Contents)
+
+## vstring
+```v
+fn (bp &u8) vstring() string
+```
+
+vstring converts a C style string to a V string.
+
+Note: the memory block pointed by `bp` is *reused, not copied*!
+
+Note: instead of `&u8(arr.data).vstring()`, do use `tos_clone(&u8(arr.data))`. Strings returned from this function will be normal V strings beside that, (i.e. they would be freed by V's -autofree mechanism, when they are no longer used). See also `tos_clone`.
+
+[[Return to contents]](#Contents)
+
+## vstring_literal
+```v
+fn (bp &u8) vstring_literal() string
+```
+
+vstring_literal converts a C style string to a V string.
+
+Note: the memory block pointed by `bp` is *reused, not copied*! NB2: unlike vstring, vstring_literal will mark the string as a literal, so it will not be freed by -autofree. This is suitable for readonly strings, C string literals etc, that can be read by the V program, but that should not be managed/freed by it, for example `os.args` is implemented using it. See also `tos_clone`.
+
+[[Return to contents]](#Contents)
+
+## vstring_literal_with_len
+```v
+fn (bp &u8) vstring_literal_with_len(len int) string
+```
+
+vstring_with_len converts a C style string to a V string.
+
+Note: the memory block pointed by `bp` is *reused, not copied*! This method has lower overhead compared to .vstring_literal(), since it does not need to calculate the length of the 0 terminated string. See also `tos_clone`.
+
+[[Return to contents]](#Contents)
+
+## vstring_with_len
+```v
+fn (bp &u8) vstring_with_len(len int) string
+```
+
+vstring_with_len converts a C style 0 terminated string to a V string.
+
+Note: the memory block pointed by `bp` is *reused, not copied*! This method has lower overhead compared to .vstring(), since it does not need to calculate the length of the 0 terminated string. See also `tos_clone`.

+
+array is a struct, used for denoting all array types in V. `.data` is a void pointer to the backing heap memory block, which avoids using generics and thus without generating extra code for every type.

+
+## ensure_cap
+```v
+fn (mut a array) ensure_cap(required int)
+```
+
+ensure_cap increases the `cap` of an array to the required value, if needed. It does so by copying the data to a new memory location (creating a clone), unless `a.cap` is already large enough.
+
+[[Return to contents]](#Contents)

+## repeat
+```v
+fn (a array) repeat(count int) array

+
+repeat returns a new array with the given array elements repeated given times. `cgen` will replace this with an appropriate call to `repeat_to_depth()`
+
+This is a dummy placeholder that will be overridden by `cgen` with an appropriate call to `repeat_to_depth()`. However the `checker` needs it here.
+
+[[Return to contents]](#Contents)
+
+## repeat_to_depth
+```v
+fn (a array) repeat_to_depth(count int, depth int) array
+```
+
+repeat_to_depth is an unsafe version of `repeat()` that handles multi-dimensional arrays.
+
+It is `unsafe` to call directly because `depth` is not checked
+
+[[Return to contents]](#Contents)
+
+## insert
+```v
+fn (mut a array) insert(i int, val voidptr)
+```
+
+insert inserts a value in the array at index `i` and increases the index of subsequent elements by 1.
+
+This function is type-aware and can insert items of the same or lower dimensionality as the original array. That is, if the original array is `[]int`, then the insert `val` may be `int` or `[]int`. If the original array is `[][]int`, then `val` may be `[]int` or `[][]int`. Consider the examples.
+
+
+
+Example
+```v
+
+mut a := [1, 2, 4]
+a.insert(2, 3) // a now is [1, 2, 3, 4]
+mut b := [3, 4]
+b.insert(0, [1, 2]) // b now is [1, 2, 3, 4]
+mut c := [[3, 4]]
+c.insert(0, [1, 2]) // c now is [[1, 2], [3, 4]]
+
+```
+
+[[Return to contents]](#Contents)
+
+## prepend
+```v
+fn (mut a array) prepend(val voidptr)

+
+[[Return to contents]](#Contents)
+
+## delete
+```v
+fn (mut a array) delete(i int)
+```
+
+delete deletes array element at index `i`. This is exactly the same as calling `.delete_many(i, 1)`.
+
+Note: This function does NOT operate in-place. Internally, it creates a copy of the array, skipping over the element at `i`, and then points the original variable to the new memory location.
+
+
+
+Example
+```v
+
+mut a := ['0', '1', '2', '3', '4', '5']
+a.delete(1) // a is now ['0', '2', '3', '4', '5']
+
+```
+
+[[Return to contents]](#Contents)
+
+## delete_many
+```v
+fn (mut a array) delete_many(i int, size int)
+```
+
+delete_many deletes `size` elements beginning with index `i`
+
+Note: This function does NOT operate in-place. Internally, it creates a copy of the array, skipping over `size` elements starting at `i`, and then points the original variable to the new memory location.
+
+
+
+Example
+```v
+
+mut a := [1, 2, 3, 4, 5, 6, 7, 8, 9]
+b := unsafe { a[..9] } // creates a `slice` of `a`, not a clone
+a.delete_many(4, 3) // replaces `a` with a modified clone
+dump(a) // a: [1, 2, 3, 4, 8, 9] // `a` is now different
+dump(b) // b: [1, 2, 3, 4, 5, 6, 7, 8, 9] // `b` is still the same
+
+```
+
+[[Return to contents]](#Contents)
+
+## clear
+```v
+fn (mut a array) clear()
+```
+
+clear clears the array without deallocating the allocated data. It does it by setting the array length to `0`
+
+Example
+```v
+
+mut a := [1,2]; a.clear(); assert a.len == 0
+
+```
+
+[[Return to contents]](#Contents)
+
+## reset
+```v
+fn (mut a array) reset()
+```
+
+reset quickly sets the bytes of all elements of the array to 0. Useful mainly for numeric arrays. Note, that calling reset() is not safe, when your array contains more complex elements, like structs, maps, pointers etc, since setting them to 0, can later lead to hard to find bugs.
+
+[[Return to contents]](#Contents)
+
+## trim
+```v
+fn (mut a array) trim(index int)
+```
+
+trim trims the array length to `index` without modifying the allocated data. If `index` is greater than `len` nothing will be changed.
+
+Example
+```v
+
+mut a := [1,2,3,4]; a.trim(3); assert a.len == 3
+
+```
+
+[[Return to contents]](#Contents)
+
+## drop
+```v
+fn (mut a array) drop(num int)
+```
+
+drop advances the array past the first `num` elements whilst preserving spare capacity. If `num` is greater than `len` the array will be emptied.
+
+Example
+```v
+
+mut a := [1,2]
+a << 3
+a.drop(2)
+assert a == [3]
+assert a.cap > a.len
+
+```
+
+[[Return to contents]](#Contents)
+
+## first
+```v
+fn (a array) first() voidptr
+```
+
+first returns the first element of the `array`. If the `array` is empty, this will panic. However, `a[0]` returns an error object so it can be handled with an `or` block.
+
+[[Return to contents]](#Contents)
+
+## last
+```v
+fn (a array) last() voidptr
+```
+
+last returns the last element of the `array`. If the `array` is empty, this will panic.
+
+[[Return to contents]](#Contents)
+
+## pop_left
+```v
+fn (mut a array) pop_left() voidptr
+```
+
+pop_left returns the first element of the array and removes it by advancing the data pointer. If the `array` is empty, this will panic.
+
+Note: This function:- Reduces both length and capacity by 1
+- Advances the underlying data pointer by one element
+- Leaves subsequent elements in-place (no memory copying)
+Sliced views will retain access to the original first element position, which is now detached from the array's active memory range.
+
+
+
+Example
+```v
+
+mut a := [1, 2, 3, 4, 5]
+b := unsafe { a[..5] } // full slice view
+first := a.pop_left()
+
+// Array now starts from second element
+dump(a) // a: [2, 3, 4, 5]
+assert a.len == 4
+assert a.cap == 4
+
+// Slice retains original memory layout
+dump(b) // b: [1, 2, 3, 4, 5]
+assert b.len == 5
+
+assert first == 1
+
+// Modifications affect both array and slice views
+a[0] = 99
+assert b[1] == 99 // changed in both
+
+```
+
+[[Return to contents]](#Contents)
+
+## pop
+```v
+fn (mut a array) pop() voidptr
+```
+
+pop returns the last element of the array, and removes it. If the `array` is empty, this will panic.
+
+Note: this function reduces the length of the given array, but arrays sliced from this one will not change. They still retain their "view" of the underlying memory.
+
+
+
+Example
+```v
+
+mut a := [1, 2, 3, 4, 5, 6, 7, 8, 9]
+b := unsafe{ a[..9] } // creates a "view" (also called a slice) into the same memory
+c := a.pop()
+assert c == 9
+a[1] = 5
+dump(a) // a: [1, 5, 3, 4, 5, 6, 7, 8]
+dump(b) // b: [1, 5, 3, 4, 5, 6, 7, 8, 9]
+assert a.len == 8
+assert b.len == 9
+
+```
+
+[[Return to contents]](#Contents)
+
+## delete_last
+```v
+fn (mut a array) delete_last()
+```
+
+delete_last efficiently deletes the last element of the array. It does it simply by reducing the length of the array by 1. If the array is empty, this will panic. See also: [trim](#array.trim)

+
+## clone

+```v
+fn (a array) filter(predicate fn (voidptr) bool) array
+```
+
+filter creates a new array with all elements that pass the test. Ignore the function signature. `filter` does not take an actual callback. Rather, it takes an `it` expression.
+
+Certain array functions (`filter` `any` `all`) support a simplified domain-specific-language by the backend compiler to make these operations more idiomatic to V. These functions are described here, but their implementation is compiler specific.
+
+Each function takes a boolean test expression as its single argument. These test expressions may use `it` as a pointer to a single element at a time.
+
+
+
+Examples
+```v
+
+a := [10,20,30,3,5,99]; assert a.filter(it < 5) == [3] // create an array of elements less than 5
+
+a := [10,20,30,3,5,99]; assert a.filter(it % 2 == 1) == [3,5,99] // create an array of only odd elements
+
+struct Named { name string }; a := [Named{'Abc'}, Named{'Bcd'}, Named{'Az'}]; assert a.filter(it.name[0] == `A`).len == 2
+
+```

+
+## any
+```v
+fn (a array) any(predicate fn (voidptr) bool) bool
+```
+
+any tests whether at least one element in the array passes the test. Ignore the function signature. `any` does not take an actual callback. Rather, it takes an `it` expression. It returns `true` if it finds an element passing the test. Otherwise, it returns `false`. It doesn't modify the array.
+
+
+
+Examples
+```v
+
+a := [2,3,4]; assert a.any(it % 2 == 1) // 3 is odd, so this will pass
+
+struct Named { name string }; a := [Named{'Bob'}, Named{'Bilbo'}]; assert a.any(it.name == 'Bob') // the first element will match
+
+```
+
+[[Return to contents]](#Contents)
+
+## count
+```v
+fn (a array) count(predicate fn (voidptr) bool) int
+```
+
+count counts how many elements in array pass the test. Ignore the function signature. `count` does not take an actual callback. Rather, it takes an `it` expression.
+
+
+
+Example
+```v
+
+a := [10,3,5,7]; assert a.count(it % 2 == 1) == 3 // will return how many elements are odd
+
+```
+
+[[Return to contents]](#Contents)
+
+## all
+```v
+fn (a array) all(predicate fn (voidptr) bool) bool
+```
+
+all tests whether all elements in the array pass the test. Ignore the function signature. `all` does not take an actual callback. Rather, it takes an `it` expression. It returns `false` if any element fails the test. Otherwise, it returns `true`. It doesn't modify the array.
+
+
+
+Example
+```v
+
+a := [3,5,7,9]; assert a.all(it % 2 == 1) // will return true if every element is odd
+
+```
+
+[[Return to contents]](#Contents)
+
+## map
+```v
+fn (a array) map(callback fn (voidptr) voidptr) array
+```
+
+map creates a new array populated with the results of calling a provided function on every element in the calling array. It also accepts an `it` expression.
+
+
+
+Example
+```v
+
+words := ['hello', 'world']
+r1 := words.map(it.to_upper())
+assert r1 == ['HELLO', 'WORLD']
+
+// map can also accept anonymous functions
+r2 := words.map(fn (w string) string {
+ return w.to_upper()
+})
+assert r2 == ['HELLO', 'WORLD']
+
+```
+
+[[Return to contents]](#Contents)
+
+## sort
+```v
+fn (mut a array) sort(callback fn (voidptr, voidptr) int)
+```
+
+sort sorts the array in place. Ignore the function signature. Passing a callback to `.sort` is not supported for now. Consider using the `.sort_with_compare` method if you need it.
+
+sort can take a boolean test expression as its single argument. The expression uses 2 'magic' variables `a` and `b` as pointers to the two elements being compared.
+
+
+
+Examples
+```v
+
+mut aa := [5,2,1,10]; aa.sort(); assert aa == [1,2,5,10] // will sort the array in ascending order
+
+mut aa := [5,2,1,10]; aa.sort(b < a); assert aa == [10,5,2,1] // will sort the array in descending order
+
+struct Named { name string }; mut aa := [Named{'Abc'}, Named{'Xyz'}]; aa.sort(b.name < a.name); assert aa.map(it.name) == ['Xyz','Abc'] // will sort descending by the .name field
+
+```
+
+[[Return to contents]](#Contents)
+
+## sorted
+```v
+fn (a &array) sorted(callback fn (voidptr, voidptr) int) array
+```
+
+sorted returns a sorted copy of the original array. The original array is *NOT* modified. See also .sort() .
+
+Examples
+```v
+
+assert [9,1,6,3,9].sorted() == [1,3,6,9,9]
+
+assert [9,1,6,3,9].sorted(b < a) == [9,9,6,3,1]
+
+```
+
+[[Return to contents]](#Contents)
+
+## sort_with_compare
+```v
+fn (mut a array) sort_with_compare(callback fn (voidptr, voidptr) int)
+```
+
+sort_with_compare sorts the array in-place using the results of the given function to determine sort order.
+
+The function should return one of three values:- `-1` when `a` should come before `b` ( `a < b` )
+- `1` when `b` should come before `a` ( `b < a` )
+- `0` when the order cannot be determined ( `a == b` )
+
+
+
+Example
+```v
+
+mut a := ['hi', '1', '5', '3']
+a.sort_with_compare(fn (a &string, b &string) int {
+ if a < b {
+ return -1
+ }
+ if a > b {
+ return 1
+ }
+ return 0
+})
+assert a == ['1', '3', '5', 'hi']

+
+[[Return to contents]](#Contents)
+
+## contains
+```v
+fn (a array) contains(value voidptr) bool
+```
+
+contains determines whether an array includes a certain value among its elements. It will return `true` if the array contains an element with this value. It is similar to `.any` but does not take an `it` expression.
+
+
+
+Example
+```v
+
+assert [1, 2, 3].contains(4) == false
+
+```

+## match_glob
+```v
+fn (name string) match_glob(pattern string) bool
+```
+
+match_glob matches the string, with a Unix shell-style wildcard pattern.
+
+Note: wildcard patterns are NOT the same as regular expressions. They are much simpler, and do not allow backtracking, captures, etc. The special characters used in shell-style wildcards are: `*` - matches everything `?` - matches any single character `[seq]` - matches any of the characters in the sequence `[^seq]` - matches any character that is NOT in the sequence Any other character in `pattern`, is matched 1:1 to the corresponding character in `name`, including / and \. You can wrap the meta-characters in brackets too, i.e. `[?]` matches `?` in the string, and `[*]` matches `*` in the string.
+
+Examples
+```v
+
+assert 'ABCD'.match_glob('AB*')
+
+assert 'ABCD'.match_glob('*D')

+## parse_int
+```v
+fn (s string) parse_int(_base int, _bit_size int) !i64
+```
+
+parse_int interprets a string s in the given base (0, 2 to 36) and bit size (0 to 64) and returns the corresponding value i.
+
+If the base argument is 0, the true base is implied by the string's prefix: 2 for "0b", 8 for "0" or "0o", 16 for "0x", and 10 otherwise. Also, for argument base 0 only, underscore characters are permitted as defined by the Go syntax for integer literals.
+
+The bitSize argument specifies the integer type that the result must fit into. Bit sizes 0, 8, 16, 32, and 64 correspond to int, int8, int16, int32, and int64. If bitSize is below 0 or above 64, an error is returned.
+
+This method directly exposes the `parse_int` function from `strconv` as a method on `string`. For more advanced features, consider calling `strconv.common_parse_int` directly.

+
+## wrap
+```v
+fn (s string) wrap(config WrapConfig) string
+```
+
+wrap wraps the string `s` when each line exceeds the width specified in `width` . (default value is 80), and will use `end` (default value is '\n') as a line break.
+
+Example
+```v
+
+assert 'Hello, my name is Carl and I am a delivery'.wrap(width: 20) == 'Hello, my name is\nCarl and I am a\ndelivery'

+## Constants
+```v
+const zero = from_rune(0)
+```
+
+zero is a Character, that in C L"" strings represents the string end character (terminator).
+
+[[Return to contents]](#Contents)
+
+## from_rune
+```v
+fn from_rune(r rune) Character
+```
+
+from_rune creates a Character, given a V rune
+
+[[Return to contents]](#Contents)
+
+## from_string
+```v
+fn from_string(s string) &Character
+```
+
+from_string converts the V string (in UTF-8 encoding), into a newly allocated platform specific buffer of C.wchar_t . The conversion is done by processing each rune of the input string 1 by 1.
+
+[[Return to contents]](#Contents)
+
+## length_in_bytes
+```v
+fn length_in_bytes(p voidptr) int
+```
+
+length_in_bytes returns the length of the given wchar_t* wide C style L"" string in bytes. Note that the size of wchar_t is different on the different platforms, thus the length in bytes for the same data converted from UTF-8 to a &Character buffer, will be different as well. i.e. unsafe { wchar.length_in_bytes(wchar.from_string('abc')) } will be 12 on unix, but 6 on windows.
+
+[[Return to contents]](#Contents)
+
+## length_in_characters
+```v
+fn length_in_characters(p voidptr) int
+```
+
+See also `length_in_bytes` .
+
+Example
+```v
+
+assert unsafe { wchar.length_in_characters(wchar.from_string('abc')) } == 3
+
+```
+
+[[Return to contents]](#Contents)
+
+## to_string
+```v
+fn to_string(p voidptr) string
+```
+
+to_string creates a V string, encoded in UTF-8, given a wchar_t* wide C style L"" string. It relies that the string has a 0 terminator at its end, to determine the string's length. Note, that the size of wchar_t is platform-dependent, and is *2 bytes* on windows, while it is *4 bytes* on most everything else. Unless you are interfacing with a C library, that does specifically use `wchar_t`, consider using `string_from_wide` instead, which will always assume that the input data is in an UTF-16 encoding, no matter what the platform is.
+
+[[Return to contents]](#Contents)
+
+## to_string2
+```v
+fn to_string2(p voidptr, len int) string
+```
+
+to_string2 creates a V string, encoded in UTF-8, given a `C.wchar_t*` wide C style L"" string. Note, that the size of `C.wchar_t` is platform-dependent, and is *2 bytes* on windows, while *4* on most everything else. Unless you are interfacing with a C library, that does specifically use wchar_t, consider using string_from_wide2 instead, which will always assume that the input data is in an UTF-16 encoding, no matter what the platform is.
+
+[[Return to contents]](#Contents)
+
+## Character
+```v
+type Character = C.wchar_t
+```
+
+Character is a type, that eases working with the platform dependent C.wchar_t type.
+
+Note: the size of C.wchar_t varies between platforms, it is 2 bytes on windows, and usually 4 bytes elsewhere.
+
+[[Return to contents]](#Contents)
+
+## str
+```v
+fn (a Character) str() string
+```
+
+return a string representation of the given Character
+
+[[Return to contents]](#Contents)
+
+## ==
+```v
+fn (a Character) == (b Character) bool
+```
+
+== is an equality operator, to ease comparing Characters
+
+Todo: the default == operator, that V generates, does not work for C.wchar_t .
+
+[[Return to contents]](#Contents)
+
+## to_rune
+```v
+fn (c Character) to_rune() rune
+```
+
+to_rune creates a V rune, given a Character

+## set_bytes_with_clamping
+```v

+```
+
+set_bytes_with_clamping applies the buffer pruning described in RFC 8032, Section 5.1.5 (also known as clamping) and sets s to the result. The input must be 32 bytes, and it is not modified. If x is not of the right length, `set_bytes_with_clamping` returns an error, and the receiver is unchanged.
+
+Note that since Scalar values are always reduced modulo the prime order of the curve, the resulting value will not preserve any of the cofactor-clearing properties that clamping is meant to provide. It will however work as expected as long as it is applied to points on the prime order subgroup, like in Ed25519. In fact, it is lost to history why RFC 8032 adopted the irrelevant RFC 7748 clamping, but it is now required for compatibility.

+## generate_key
+```v
+fn generate_key(opt CurveOptions) !(PublicKey, PrivateKey)
+```
+
+generate_key generates a new key pair. If opt was not provided, its default to prime256v1 curve. If you want another curve, use `pubkey, pivkey := ecdsa.generate_key(nid: .secp384r1)!` instead.
+

+
+## new_key_from_seed
+```v
+fn new_key_from_seed(seed []u8, opt CurveOptions) !PrivateKey
+```
+
+new_key_from_seed creates a new private key from the seed bytes. If opt was not provided, its default to prime256v1 curve.
+
+Notes on the seed:
+
+You should make sure, the seed bytes come from a cryptographically secure random generator, likes the `crypto.rand` or other trusted sources. Internally, the seed size's would be checked to not exceed the key size of underlying curve, ie, 32 bytes length for p-256 and secp256k1, 48 bytes length for p-384 and 66 bytes length for p-521. Its recommended to use seed with bytes length matching with underlying curve key size.

+
+Examples:
+```codeblock

+```v
+fn decode(data string) []u8
+```
+
+decode decodes the base64 encoded `string` value passed in `data`. Please note: If you need to decode many strings repeatedly, take a look at `decode_in_buffer`.
+
+Example
+```v
+
+assert base64.decode('ViBpbiBiYXNlIDY0') == 'V in base 64'.bytes()
+
+```
+
+[[Return to contents]](#Contents)
+
+## decode_in_buffer
+```v
+fn decode_in_buffer(data &string, buffer &u8) int
+```
+
+decode_in_buffer decodes the base64 encoded `string` reference passed in `data` into `buffer`. decode_in_buffer returns the size of the decoded data in the buffer. Please note: The `buffer` should be large enough (i.e. 3/4 of the data.len, or larger) to hold the decoded data. Please note: This function does NOT allocate new memory, and is thus suitable for handling very large strings.
+
+[[Return to contents]](#Contents)
+
+## decode_in_buffer_bytes
+```v
+fn decode_in_buffer_bytes(data []u8, buffer &u8) int
+```
+
+decode_from_buffer decodes the base64 encoded ASCII bytes from `data` into `buffer`. decode_from_buffer returns the size of the decoded data in the buffer. Please note: The `buffer` should be large enough (i.e. 3/4 of the data.len, or larger) to hold the decoded data. Please note: This function does NOT allocate new memory, and is thus suitable for handling very large strings.

+
+## encode
+```v
+fn encode(data []u8) string
+```
+
+encode encodes the `[]u8` value passed in `data` to base64. Please note: base64 encoding returns a `string` that is ~ 4/3 larger than the input. Please note: If you need to encode many strings repeatedly, take a look at `encode_in_buffer`.
+
+Example
+```v
+
+assert base64.encode('V in base 64'.bytes()) == 'ViBpbiBiYXNlIDY0'
+
+```

+## escape
+```v
+fn escape(input string, config EscapeConfig) string
+```
+
+escape converts special characters in the input, specifically "<", ">", and "&" to HTML-safe sequences. If `quote` is set to true (which is default), quotes in HTML will also be translated. Both double and single quotes will be affected. **Note:** escape() supports funky accents by doing nothing about them. V's UTF-8 support through `string` is robust enough to deal with these cases.

+
+## unescape
+```v
+fn unescape(input string, config UnescapeConfig) string
+```
+
+unescape converts entities like "<" to "<". By default it is the converse of `escape`. If `all` is set to true, it handles named, numeric, and hex values - for example, `'''`, `'''`, and `'''` then unescape to "'".
