+# filemap Module
+
+Parse directories or formatted strings into file maps with automatic ignore pattern support.
+
+## Features
+
+- 📂 Walk directories recursively and build file maps
+- 🚫 Respect `.gitignore` and `.heroignore` ignore patterns with directory scoping
+- 📝 Parse custom `===FILE:name===` format into file maps
+- 📦 Export/write file maps to disk
+- 🛡️ Robust, defensive parsing (handles spaces, variable `=` length, case-insensitive)
+
+## Quick Start
+
+### From Directory Path
+
+```v
+import incubaid.herolib.lib.ai.filemap
+
+mut cw := filemap.new()
+mut fm := cw.filemap_get(path: '/path/to/project')!
+
+// Iterate files
+for path, content in fm.content {
+    println('${path}: ${content.len} bytes')
+}
+```
+
+### From Formatted String
+
+```v
+content_str := '
+===FILE:main.v===
+fn main() {
+    println("Hello!")
+}
+===FILE:utils/helper.v===
+pub fn help() {}
+===END===
+'
+
+mut cw := filemap.new()
+mut fm := cw.parse(content_str)!
+
+println(fm.get('main.v')!)
+```
+
+## FileMap Operations
+
+```v
+// Get file content
+content := fm.get('path/to/file.txt')!
+
+// Set/modify file
+fm.set('new/file.txt', 'content here')
+
+// Find files by prefix
+files := fm.find('src/')
+
+// Export to directory
+fm.export('/output/dir')!
+
+// Write updates to directory
+fm.write('/project/dir')!
+
+// Convert back to formatted string
+text := fm.content()
+```
+
+## File Format
+
+### Full Files
+
+```
+===FILE:path/to/file.txt===
+File content here
+Can span multiple lines
+===END===
+```
+
+### Partial Content (for future morphing)
+
+```
+===FILECHANGE:src/models.v===
+struct User {
+    id int
+}
+===END===
+```
+
+### Both Together
+
+```
+===FILE:main.v===
+fn main() {}
+===FILECHANGE:utils.v===
+fn helper() {}
+===END===
+```
+
+## Parsing Robustness
+
+Parser handles variations:
+
+```
+===FILE:name.txt===     // Standard
+== FILE : name.txt ==   
+===file:name.txt===     // Lowercase
+==FILE:name.txt==       // Different = count
+```
+
+## Error Handling
+
+Errors are collected in `FileMap.errors`:
+
+```v
+mut fm := cw.filemap_get(content: str)!
+
+if fm.errors.len > 0 {
+    for err in fm.errors {
+        println('Line ${err.linenr}: ${err.message}')
+    }
+}
+```
+
+## Ignore Patterns
+
+- Respects `.gitignore` and `.heroignore` in any parent directory
+- Default patterns include `.git/`, `node_modules/`, `*.pyc`, etc.
+- Use `/` suffix for directory patterns: `dist/`
+- Use `*` for wildcards: `*.log`
+- Lines starting with `#` are comments
+
+Example `.heroignore`:
+
+```
+build/
+*.tmp
+.env
+__pycache__/
+```

 # Code Model
 
-A set of models that represent code, such as structs and functions. The motivation behind this module is to provide a more generic, and lighter alternative to v.ast code models, that can be used for code parsing and code generation across multiple languages.
+A comprehensive module for parsing, analyzing, and generating V code. The Code Model provides lightweight, language-agnostic structures to represent code elements like structs, functions, imports, and types.
 
-## Using Codemodel
+## Overview
 
-While the models in this module can be used in any domain, the models here are used extensively in the modules [codeparser](../codeparser/) and codegen (under development). Below are examples on how codemodel can be used for parsing and generating code.
-## Code parsing with codemodel
+The `code` module is useful for:
 
-As shown in the example below, the codemodels returned by the parser can be used to infer information about the code written
+- **Code Parsing**: Parse V files into structured models
+- **Code Analysis**: Extract information about functions, structs, and types
+- **Code Generation**: Generate V code from models using `vgen()`
+- **Static Analysis**: Inspect and traverse code using language utilities
+- **Documentation Generation**: Serialize code into other formats (JSON, Markdown, etc.)
 
-```js
-code := codeparser.parse("somedir") // code is a list of code models
+## Core Components
 
-num_functions := code.filter(it is Function).len
-structs := code.filter(it is Struct)
-println("This directory has ${num_functions} functions")
-println('The directory has the structs: ${structs.map(it.name)}')
+### Code Structures (Models)
 
+- **`Struct`**: Represents V struct definitions with fields, visibility, and generics
+- **`Function`**: Represents functions/methods with parameters, return types, and bodies
+- **`Interface`**: Represents V interface definitions
+- **`VFile`**: Represents a complete V file with module, imports, constants, and items
+- **`Module`**: Represents a V module with nested files and folders
+- **`Import`**: Represents import statements
+- **`Param`**: Represents function parameters with types and modifiers
+- **`Type`**: Union type supporting arrays, maps, results, objects, and basic types
+- **`Const`**: Represents constant definitions
+
+### Type System
+
+The `Type` union supports:
+- Basic types: `String`, `Boolean`, `Integer` (signed/unsigned, 8/16/32/64-bit)
+- Composite types: `Array`, `Map`, `Object`
+- Function types: `Function`
+- Result types: `Result` (for error handling with `!`)
+- Aliases: `Alias`
+
+## Usage Examples
+
+### Parsing a V File
+
+```v
+import incubaid.herolib.core.code
+import os
+
+// Read and parse a V file
+content := os.read_file('path/to/file.v')!
+vfile := code.parse_vfile(content)!
+
+// Access parsed elements
+println('Module: ${vfile.mod}')
+println('Imports: ${vfile.imports.len}')
+println('Structs: ${vfile.structs().len}')
+println('Functions: ${vfile.functions().len}')
 ```
 
-or can be used as intermediate structures to serialize code into some other format:
+### Analyzing Structs
 
-```js
-code_md := ''
+```v
+import incubaid.herolib.core.code
 
-// describes the struct in markdown format
-for struct in structs {
-    code_md += '# ${struct.name}'
-    code_md += 'Type: ${struct.typ.symbol()}'
-    code_md += '## Fields:'
-    for field in struct.fields {
-        code_md += '- ${field.name}'
+// Parse a struct definition
+struct_code := 'pub struct User {
+pub:
+    name string
+    age  int
+}'
+
+vfile := code.parse_vfile(struct_code)!
+structs := vfile.structs()
+
+for struct_ in structs {
+    println('Struct: ${struct_.name}')
+    println('  Is public: ${struct_.is_pub}')
+    for field in struct_.fields {
+        println('  Field: ${field.name} (${field.typ.symbol()})')
     }
 }
 ```
 
-The [openrpc/docgen](../openrpc/docgen/) module demonstrates a good use case, where codemodels are serialized into JSON schema's, to generate an OpenRPC description document from a client in v.## V Language Utilities
-
-The `vlang_utils.v` file provides a set of utility functions for working with V language files and code. These utilities are useful for:
-
-1. **File Operations**
-   - `list_v_files(dir string) ![]string` - Lists all V files in a directory, excluding generated files
-   - `get_module_dir(mod string) string` - Converts a V module path to a directory path
-
-2. **Code Inspection and Analysis**
-   - `get_function_from_file(file_path string, function_name string) !string` - Extracts a function definition from a file
-   - `get_function_from_module(module_path string, function_name string) !string` - Searches for a function across all files in a module
-   - `get_type_from_module(module_path string, type_name string) !string` - Searches for a type definition across all files in a module
-
-3. **V Language Tools**
-   - `vtest(fullpath string) !string` - Runs V tests on files or directories
-   - `vvet(fullpath string) !string` - Runs V vet on files or directories
-
-### Example Usage
+### Analyzing Functions
 
 ```v
-// Find and extract a function definition
-function_def := code.get_function_from_module('/path/to/module', 'my_function') or {
-    eprintln('Could not find function: ${err}')
-    return
-}
-println(function_def)
+import incubaid.herolib.core.code
 
-// Run tests on a directory
-test_results := code.vtest('/path/to/module') or {
-    eprintln('Tests failed: ${err}')
-    return
+fn_code := 'pub fn greet(name string) string {
+    return "Hello, \${name}!"
+}'
+
+vfile := code.parse_vfile(fn_code)!
+functions := vfile.functions()
+
+for func in functions {
+    println('Function: ${func.name}')
+    println('  Public: ${func.is_pub}')
+    println('  Parameters: ${func.params.len}')
+    println('  Returns: ${func.result.typ.symbol()}')
 }
-println(test_results)
 ```
 
-These utilities are particularly useful when working with code generation, static analysis, or when building developer tools that need to inspect V code.
+### Code Generation
+
+```v
+import incubaid.herolib.core.code
+
+// Create a struct model
+my_struct := code.Struct{
+    name: 'Person'
+    is_pub: true
+    fields: [
+        code.StructField{
+            name: 'name'
+            typ: code.type_from_symbol('string')
+            is_pub: true
+        },
+        code.StructField{
+            name: 'age'
+            typ: code.type_from_symbol('int')
+            is_pub: true
+        }
+    ]
+}
+
+// Generate V code from the model
+generated_code := my_struct.vgen()
+println(generated_code)
+// Output: pub struct Person { ... }
+```
+
+### V Language Utilities
+
+```v
+import incubaid.herolib.core.code
+
+// List all V files in a directory (excludes generated files ending with _.v)
+v_files := code.list_v_files('/path/to/module')!
+
+// Get a specific function from a module
+func := code.get_function_from_module('/path/to/module', 'my_function')!
+println('Found function: ${func.name}')
+
+// Get a type definition from a module
+type_def := code.get_type_from_module('/path/to/module', 'MyStruct')!
+println(type_def)
+
+// Run V tests
+test_results := code.vtest('/path/to/module')!
+```
+
+### Working With Modules and Files
+
+```v
+import incubaid.herolib.core.code
+
+// Create a module structure
+my_module := code.Module{
+    name: 'mymodule'
+    description: 'My awesome module'
+    version: '1.0.0'
+    license: 'apache2'
+    files: [
+        code.VFile{
+            name: 'structs'
+            mod: 'mymodule'
+            // ... add items
+        }
+    ]
+}
+
+// Write module to disk
+write_opts := code.WriteOptions{
+    overwrite: false
+    format: true
+    compile: false
+}
+my_module.write('/output/path', write_opts)!
+```
+
+### Advanced Features
+
+### Custom Code Generation
+
+```v
+import incubaid.herolib.core.code
+
+// Generate a function call from a Function model
+func := code.Function{
+    name: 'calculate'
+    params: [
+        code.Param{ name: 'x', typ: code.type_from_symbol('int') },
+        code.Param{ name: 'y', typ: code.type_from_symbol('int') }
+    ]
+    result: code.Param{ typ: code.type_from_symbol('int') }
+}
+
+call := func.generate_call(receiver: 'calculator')!
+// Output: result := calculator.calculate(...)
+```
+
+### Type Conversion
+
+```v
+import incubaid.herolib.core.code
+
+// Convert from type symbol to Type model
+t := code.type_from_symbol('[]string')
+
+// Get the V representation
+v_code := t.vgen()  // Output: "[]string"
+
+// Get the TypeScript representation
+ts_code := t.typescript()  // Output: "string[]"
+
+// Get the symbol representation
+symbol := t.symbol()  // Output: "[]string"
+```
+
+## Complete Example
+
+See the working example at **`examples/core/code/code_parser.vsh`** for a complete demonstration of:
+
+- Listing V files in a directory
+- Parsing multiple V files
+- Extracting and analyzing structs and functions
+- Summarizing module contents
+
+Run it with:
+```bash
+vrun ~/code/github/incubaid/herolib/examples/core/code/code_parser.vsh
+```
+
+## Coding Instructions
+
+When using the Code module:
+
+1.  **Always parse before analyzing**: Use `parse_vfile()`, `parse_struct()`, or `parse_function()` to create models from code strings
+2.  **Use type filters**: Filter code items by type using `.filter(it is StructType)` pattern
+3.  **Check visibility**: Always verify `is_pub` flag when examining public API
+4.  **Handle errors**: Code parsing can fail; always use `!` or `or` blocks
+5.  **Generate code carefully**: Use `WriteOptions` to control formatting, compilation, and testing
+6.  **Use language utilities**: Prefer `get_function_from_module()` over manual file searching
+7.  **Cache parsed results**: Store `VFile` objects if you need to access them multiple times
+8.  **Document generated code**: Add descriptions to generated structs and functions
+

-# Code Review and Improvement Plan for HeroLib Code Module
-
-## Overview
-
-The HeroLib `code` module provides utilities for parsing and generating V language code. It's designed to be a lightweight alternative to `v.ast` for code analysis and generation across multiple languages. While the module has good foundational structure, there are several areas that need improvement.
-
-## Issues Identified
-
-### 1. Incomplete TypeScript Generation Support
-
-- The `typescript()` method exists in some models but lacks comprehensive implementation
-- Missing TypeScript generation for complex types (arrays, maps, results)
-- No TypeScript interface generation for structs
-
-### 2. Template System Issues
-
-- Some templates are empty (e.g., `templates/function/method.py`, `templates/comment/comment.py`)
-- Template usage is inconsistent across the codebase
-- No clear separation between V and other language templates
-
-### 3. Missing Parser Documentation Examples
-
-- README.md mentions codeparser but doesn't show how to use the parser from this module
-- No clear examples of parsing V files or modules
-
-### 4. Incomplete Type Handling
-
-- The `parse_type` function doesn't handle all V language types comprehensively
-- Missing support for function types, sum types, and complex generics
-- No handling of optional types (`?Type`)
-
-### 5. Code Structure and Consistency
-
-- Some functions lack proper error handling
-- Inconsistent naming conventions in test files
-- Missing documentation for several key functions
-
-## Improvement Plan
-
-### 1. Complete TypeScript Generation Implementation
-
-**What needs to be done:**
-
-- Implement comprehensive TypeScript generation in `model_types.v`
-- Add TypeScript generation for all type variants
-- Create proper TypeScript interface generation in `model_struct.v`
-
-**Specific fixes:**
-
-```v
-// In model_types.v, improve the typescript() method:
-pub fn (t Type) typescript() string {
-  return match t {
-    Map { 'Record<string, ${t.typ.typescript()}>' }
-    Array { '${t.typ.typescript()}[]' }
-    Object { t.name }
-    Result { 'Promise<${t.typ.typescript()}>' } // Better representation for async operations
-    Boolean { 'boolean' }
-    Integer { 'number' }
-    Alias { t.name }
-    String { 'string' }
-    Function { '(...args: any[]) => any' } // More appropriate for function types
-    Void { 'void' }
-  }
-}
-
-// In model_struct.v, improve the typescript() method:
-pub fn (s Struct) typescript() string {
-  name := texttools.pascal_case(s.name)
-  fields := s.fields.map(it.typescript()).join('\n  ')
-  return 'export interface ${name} {\n  ${fields}\n}'
-}
-```
-
-### 2. Fix Template System
-
-**What needs to be done:**
-
-- Remove empty Python template files
-- Ensure all templates are properly implemented
-- Add template support for other languages
-
-**Specific fixes:**
-
-- Delete `templates/function/method.py` and `templates/comment/comment.py` if they're not needed
-- Add proper TypeScript templates for struct and interface generation
-- Create consistent template naming conventions
-
-### 3. Improve Parser Documentation
-
-**What needs to be done:**
-
-- Add clear examples in README.md showing how to use the parser
-- Document the parsing functions with practical examples
-
-**Specific fixes:**
-Add to README.md:
-
-```markdown
-## Parsing V Code
-
-The code module provides utilities to parse V code into structured models:
-
-```v
-import incubaid.herolib.core.code
-
-// Parse a V file
-content := os.read_file('example.v') or { panic(err) }
-vfile := code.parse_vfile(content) or { panic(err) }
-
-// Access parsed information
-println('Module: ${vfile.mod}')
-println('Number of functions: ${vfile.functions().len}')
-println('Number of structs: ${vfile.structs().len}')
-
-// Parse individual components
-function := code.parse_function(fn_code_string) or { panic(err) }
-struct_ := code.parse_struct(struct_code_string) or { panic(err) }
-```
-
-### 4. Complete Type Handling
-
-**What needs to be done:**
-
-- Extend `parse_type` to handle more complex V types
-- Add support for optional types (`?Type`)
-- Improve generic type parsing
-
-**Specific fixes:**
-
-```v
-// In model_types.v, enhance parse_type function:
-pub fn parse_type(type_str string) Type {
-  mut type_str_trimmed := type_str.trim_space()
-  
-  // Handle optional types
-  if type_str_trimmed.starts_with('?') {
-    return Optional{parse_type(type_str_trimmed.all_after('?'))}
-  }
-  
-  // Handle function types
-  if type_str_trimmed.starts_with('fn ') {
-    // Parse function signature
-    return Function{}
-  }
-  
-  // Handle sum types
-  if type_str_trimmed.contains('|') {
-    types := type_str_trimmed.split('|').map(parse_type(it.trim_space()))
-    return Sum{types}
-  }
-  
-  // Existing parsing logic...
-}
-```
-
-### 5. Code Structure Improvements
-
-**What needs to be done:**
-
-- Add proper error handling to all parsing functions
-- Standardize naming conventions
-- Improve documentation consistency
-
-**Specific fixes:**
-
-- Add error checking in `parse_function`, `parse_struct`, and other parsing functions
-- Ensure all public functions have clear documentation comments
-- Standardize test function names
-
-## Module Generation to Other Languages
-
-### Current Implementation
-
-The current code shows basic TypeScript generation support, but it's incomplete. The generation should:
-
-1. **Support multiple languages**: The code structure allows for multi-language generation, but only TypeScript has partial implementation
-2. **Use templates consistently**: All language generation should use the template system
-3. **Separate language-specific code**: Each language should have its own generation module
-
-### What Needs to Move to Other Modules
-
-**TypeScript Generation Module:**
-
-- Move all TypeScript-specific generation code to a new `typescript` module
-- Create TypeScript templates for structs, interfaces, and functions
-- Add proper TypeScript formatting support
-
-**Example Structure:**
-
-```
-lib/core/code/
-├── model_types.v          # Core type models (language agnostic)
-├── model_struct.v         # Core struct/function models (language agnostic)
-└── typescript/            # TypeScript-specific generation
-    ├── generator.v        # TypeScript generation logic
-    └── templates/         # TypeScript templates
-```
-
-### Parser Usage Examples (to add to README.md)
-
-```v
-// Parse a V file into a structured representation
-content := os.read_file('mymodule/example.v') or { panic(err) }
-vfile := code.parse_vfile(content)!
-
-// Extract all functions
-functions := vfile.functions()
-println('Found ${functions.len} functions')
-
-// Extract all structs
-structs := vfile.structs()
-for s in structs {
-  println('Struct: ${s.name}')
-  for field in s.fields {
-    println('  Field: ${field.name} (${field.typ.symbol()})')
-  }
-}
-
-// Find a specific function
-if greet_fn := vfile.get_function('greet') {
-  println('Found function: ${greet_fn.name}')
-  println('Parameters: ${greet_fn.params.map(it.name)}')
-  println('Returns: ${greet_fn.result.typ.symbol()}')
-}
-
-// Parse a function from string
-fn_code := '
-pub fn add(a int, b int) int {
-  return a + b
-}
-'
-function := code.parse_function(fn_code)!
-println('Parsed function: ${function.name}')
-```
-
-## Summary of Required Actions
-
-1. **Implement complete TypeScript generation** across all model types
-2. **Remove empty template files** and organize templates properly
-3. **Enhance type parsing** to handle optional types, function types, and sum types
-4. **Add comprehensive parser documentation** with practical examples to README.md
-5. **Create language-specific generation modules** to separate concerns
-6. **Improve error handling** in all parsing functions
-7. **Standardize documentation and naming** conventions across the module
-
-These improvements will make the code module more robust, easier to use, and better prepared for multi-language code generation.

+# CodeParser Module
+
+The `codeparser` module provides a comprehensive indexing and analysis system for V codebases. It walks directory trees, parses all V files, and allows efficient searching, filtering, and analysis of code structures.
+
+## Features
+
+- **Directory Scanning**: Automatically walks directory trees and finds all V files
+- **Batch Parsing**: Parses multiple files efficiently
+- **Indexing**: Indexes code by module, structs, functions, interfaces, constants
+- **Search**: Find specific items by name
+- **Filtering**: Use predicates to filter code items
+- **Statistics**: Get module statistics (file count, struct count, etc.)
+- **Export**: Export complete codebase structure as JSON
+- **Error Handling**: Gracefully handles parse errors
+
+## Basic Usage
+
+```v
+import incubaid.herolib.core.codeparser
+
+// Create a parser for a directory
+mut parser := codeparser.new('/path/to/herolib')!
+
+// List all modules
+modules := parser.list_modules()
+for mod in modules {
+    println('Module: ${mod}')
+}
+
+// Find a specific struct
+struct_ := parser.find_struct('User', 'mymodule')!
+println('Struct: ${struct_.name}')
+
+// List all public functions
+pub_fns := parser.filter_public_functions()
+
+// Get methods on a struct
+methods := parser.list_methods_on_struct('User')
+
+// Export to JSON
+json_str := parser.to_json()!
+```
+
+## API Reference
+
+### Factory
+
+- `new(root_dir: string) !CodeParser` - Create parser for a directory
+
+### Listers
+
+- `list_modules() []string` - All modules
+- `list_files() []string` - All files
+- `list_files_in_module(module: string) []string` - Files in module
+- `list_structs(module: string = '') []Struct` - All structs
+- `list_functions(module: string = '') []Function` - All functions
+- `list_interfaces(module: string = '') []Interface` - All interfaces
+- `list_methods_on_struct(struct: string, module: string = '') []Function` - Methods
+- `list_imports(module: string = '') []Import` - All imports
+- `list_constants(module: string = '') []Const` - All constants
+
+### Finders
+
+- `find_struct(name: string, module: string = '') !Struct`
+- `find_function(name: string, module: string = '') !Function`
+- `find_interface(name: string, module: string = '') !Interface`
+- `find_method(struct: string, method: string, module: string = '') !Function`
+- `find_module(name: string) !ParsedModule`
+- `find_file(path: string) !ParsedFile`
+- `find_structs_with_method(method: string, module: string = '') []string`
+- `find_callers(function: string, module: string = '') []Function`
+
+### Filters
+
+- `filter_structs(predicate: fn(Struct) bool, module: string = '') []Struct`
+- `filter_functions(predicate: fn(Function) bool, module: string = '') []Function`
+- `filter_public_structs(module: string = '') []Struct`
+- `filter_public_functions(module: string = '') []Function`
+- `filter_functions_with_receiver(module: string = '') []Function`
+- `filter_functions_returning_error(module: string = '') []Function`
+- `filter_structs_with_field(type: string, module: string = '') []Struct`
+- `filter_structs_by_name(pattern: string, module: string = '') []Struct`
+- `filter_functions_by_name(pattern: string, module: string = '') []Function`
+
+### Export
+
+- `to_json(module: string = '') !string` - Export to JSON
+- `to_json_pretty(module: string = '') !string` - Pretty-printed JSON
+
+### Error Handling
+
+- `has_errors() bool` - Check if parsing errors occurred
+- `error_count() int` - Get number of errors
+- `print_errors()` - Print all errors
+
+## Example: Analyzing a Module
+
+```v
+import incubaid.herolib.core.codeparser
+
+mut parser := codeparser.new(os.home_dir() + '/code/github/incubaid/herolib/lib/core')!
+
+// Get all public functions in the 'pathlib' module
+pub_fns := parser.filter_public_functions('incubaid.herolib.core.pathlib')
+
+for fn in pub_fns {
+    println('${fn.name}() -> ${fn.result.typ.symbol()}')
+}
+
+// Find all structs with a specific method
+structs := parser.find_structs_with_method('read')
+
+// Export pathlib module to JSON
+json_str := parser.to_json('incubaid.herolib.core.pathlib')!
+println(json_str)
+```
+
+## Implementation Notes
+
+1. **Lazy Parsing**: Files are parsed only when needed
+2. **Error Recovery**: Parsing errors don't stop the indexing process
+3. **Memory Efficient**: Maintains index in memory but doesn't duplicate code
+4. **Module Agnostic**: Works with any V module structure
+5. **Cross-Module Search**: Can search across entire codebase or single module

-## Features
+## 6. Path Scanning with Filters and Executors
 
-The module handles common edge cases:
+Path scanning processes directory trees with custom filter and executor functions.
 
-- Automatically expands ~ to home directory
-- Creates parent directories as needed
-- Provides proper error handling with V's result type
-- Checks path existence and type
-- Handles both absolute and relative paths
+### 6.1 Basic Scanner Usage
 
-## Path Object Structure
+```v
+import incubaid.herolib.core.pathlib
+import incubaid.herolib.data.paramsparser
+
+// Define a filter function (return true to continue processing)
+fn my_filter(mut path pathlib.Path, mut params paramsparser.Params) !bool {
+    // Skip files larger than 1MB
+    size := path.size()!
+    return size < 1_000_000
+}
+
+// Define an executor function (process the file)
+fn my_executor(mut path pathlib.Path, mut params paramsparser.Params) !paramsparser.Params {
+    if path.is_file() {
+        content := path.read()!
+        println('Processing: ${path.name()} (${content.len} bytes)')
+    }

+
+// Run the scan
+mut root := pathlib.get_dir(path: '/source/dir')!
+mut params := paramsparser.new_params()
+root.scan(mut params, [my_filter], [my_executor])!
+```
+
+### 6.2 Scanner with Multiple Filters and Executors
+
+```v
+import incubaid.herolib.core.pathlib
+import incubaid.herolib.data.paramsparser
+
+// Filter 1: Skip hidden files
+fn skip_hidden(mut path pathlib.Path, mut params paramsparser.Params) !bool {

+
+total := params.get('total_lines')!
+println('Total lines: ${total}')
+```
+
+## 7. Sub-path Getters and Checkers
+
+```v
+// Get a sub-path with name fixing and case-insensitive matching
+path.sub_get(name: 'mysub_file.md', name_fix_find: true, name_fix: true)!
+
+// Check if a sub-path exists
+path.sub_exists(name: 'my_sub_dir')!
+
+// File operations
+path.file_exists('file.txt')              // bool
+path.file_exists_ignorecase('File.Txt')   // bool
+path.file_get('file.txt')!                // Path
+path.file_get_ignorecase('File.Txt')!     // Path
+path.file_get_new('new.txt')!             // Get or create
+
+// Directory operations
+path.dir_exists('mydir')                  // bool
+path.dir_get('mydir')!                    // Path
+path.dir_get_new('newdir')!               // Get or create
+
+// Symlink operations
+path.link_exists('mylink')                // bool
+path.link_get('mylink')!                  // Path
+```
+
+## 8. Path Object Structure
 
 Each Path object contains:
 
 - `path`: The actual path string
-- `cat`: Category (file/dir/link)
-- `exist`: Existence status
+- `cat`: Category (file/dir/linkfile/linkdir)
+- `exist`: Existence status (yes/no/unknown)
 
 This provides a safe and convenient API for all file system operations in V.
-
-## 5. Sub-path Getters and Checkers
-
-The `pathlib` module provides methods to get and check for the existence of sub-paths (files, directories, and links) within a given path.
-
-```v
-// Get a sub-path (file or directory) with various options
-path.sub_get(name:"mysub_file.md", name_fix_find:true, name_fix:true)!
-
-// Check if a sub-path exists
-path.sub_exists(name:"my_sub_dir")!
-
-// Check if a file exists
-path.file_exists("my_file.txt")
-
-// Check if a file exists (case-insensitive)
-path.file_exists_ignorecase("My_File.txt")
-
-// Get a file as a Path object
-path.file_get("another_file.txt")!
-
-// Get a file as a Path object (case-insensitive)
-path.file_get_ignorecase("Another_File.txt")!
-
-// Get a file, create if it doesn't exist
-path.file_get_new("new_file.txt")!
-
-// Check if a link exists
-path.link_exists("my_link")
-
-// Check if a link exists (case-insensitive)
-path.link_exists_ignorecase("My_Link")
-
-// Get a link as a Path object
-path.link_get("some_link")!
-
-// Check if a directory exists
-path.dir_exists("my_directory")
-
-// Get a directory as a Path object
-path.dir_get("another_directory")!
-
-// Get a directory, create if it doesn't exist
-path.dir_get_new("new_directory")!
-```

-- .
+Escapes special regex metacharacters in a string to make it safe for use in regex patterns.
+
+```v
+import incubaid.herolib.core.texttools.regext
+
+escaped := regext.escape_regex_chars("file.txt")
+// Result: "file\.txt"
+
+// Use in regex patterns:
+safe_search := regext.escape_regex_chars("[test]")
+// Result: "\[test\]"
+```
+
+**Special characters escaped**: `. ^ $ * + ? { } [ ] \ | ( )`
+
+### wildcard_to_regex
+
+Converts simple wildcard patterns to regex patterns for flexible file matching.
+
+**Conversion rules:**
+- `*` becomes `.*` (matches any sequence of characters)
+- Literal text is escaped (special regex characters are escaped)
+- Patterns without `*` match as substrings anywhere
+
+```v
+import incubaid.herolib.core.texttools.regext
+
+// Match files ending with .txt
+pattern1 := regext.wildcard_to_regex("*.txt")
+// Result: ".*\.txt"
+
+// Match anything starting with test
+pattern2 := regext.wildcard_to_regex("test*")
+// Result: "test.*"
+
+// Match anything containing 'config' (no wildcard)
+pattern3 := regext.wildcard_to_regex("config")
+// Result: ".*config.*"
+
+// Complex pattern with special chars
+pattern4 := regext.wildcard_to_regex("src/*.v")
+// Result: "src/.*\.v"
+
+// Multiple wildcards
+pattern5 := regext.wildcard_to_regex("*test*file*")
+// Result: ".*test.*file.*"
+```
+
+## Regex Group Finders
+
+### find_sid
+
+Extracts unique `sid` values from a given text. A `sid` is identified by the pattern `sid:XXXXXX`, where `XXXXXX` can be alphanumeric characters.
+
+```v
+import incubaid.herolib.core.texttools.regext
+
+text := `
+!!action.something sid:aa733
+
+sid:aa733
+

+sid:s_d
+`
+
+r := regext.find_sid(text)
+// Result: ['aa733', 'aa733', 'aa733', '997']
+```
+
+### find_simple_vars
+
+Extracts simple variable names enclosed in curly braces, e.g., `{var_name}`, from a given text. Variable names can contain letters, numbers, and underscores.
+
+```v
+import incubaid.herolib.core.texttools.regext
+
+text := `
+!!action.something {sid}

+sid:aa733

-# CodeWalker Module
-
-The CodeWalker module provides functionality to walk through directories and create a map of files with their content. It's particularly useful for processing code directories while respecting gitignore patterns.
-
-## Features
-
-- Walk through directories recursively
-- Respect gitignore patterns to exclude files
-- Store file content in memory
-- Export files back to a directory structure
-
-## Usage
-
-```v
-import incubaid.herolib.lib.lang.codewalker
-
-mut cw := codewalker.new('/tmp/adir')!
-
-// Get content of a specific file
-content := cw.filemap.get('path/to/file.txt')!
-
-// return output again
-cw.filemap.content()
-
-// Export all files to a destination directory
-cw.filemap.export('/tmp/exported_files')!
-
-```
-
-### format of filemap
-
-## full files
-
-```
-
-text before will be ignored
-
-===FILE:filename===
-code
-===FILE:filename===
-code
-===END===
-
-text behind will be ignored
-
-```
-
-## files with changes
-
-```
-
-text before will be ignored
-
-===FILECHANGE:filename===
-code
-===FILECHANGE:filename===
-code
-===END===
-
-text behind will be ignored
-
-```
-
-FILECHANGE and FILE can be mixed, in FILE it means we have full content otherwise only changed content e.g. a method or s struct and then we need to use morph to change it
