+# Pathlib Module: Advanced Listing and Filtering
+
+The `pathlib` module provides powerful capabilities for listing and filtering files and directories, especially through its `list` method. This document explains how to leverage advanced features like regular expressions and various filtering options.
+
+## Advanced File Listing with `path.list()`
+
+The `path.list()` method allows you to retrieve a `PathList` object containing `Path` objects that match specified criteria.
+
+### `ListArgs` Parameters
+
+The `list` method accepts a `ListArgs` struct to control its behavior:
+
+```v
+pub struct ListArgs {
+pub mut:
+	regex         []string // A slice of regular expressions to filter files.
+	recursive     bool = true // Whether to list files recursively (default true).
+	ignoredefault bool = true // Whether to ignore files starting with . and _ (default true).
+	include_links bool // Whether to include symbolic links in the list.
+	dirs_only     bool // Whether to include only directories in the list.
+	files_only    bool // Whether to include only files in the list.
+}
+```
+
+### Usage Examples
+
+Here are examples demonstrating how to use these advanced filtering options:
+
+#### 1. Listing Files by Regex Pattern
+
+You can use regular expressions to filter files based on their names or extensions. The `regex` parameter accepts a slice of strings, where each string is a regex pattern.
+
+```v
+import freeflowuniverse.herolib.core.pathlib
+
+// Get a directory path
+mut dir := pathlib.get('/some/directory')!
+
+// List only Vlang files (ending with .v)
+mut vlang_files := dir.list(
+    regex: [r'.*\.v$']
+)!
+
+// List only image files (png, jpg, svg, jpeg)
+mut image_files := dir.list(
+    regex: [r'.*\.png$', r'.*\.jpg$', r'.*\.svg$', r'.*\.jpeg$']
+)!
+
+// List files containing "test" in their name (case-insensitive)
+mut test_files := dir.list(
+    regex: [r'(?i).*test.*'] // (?i) makes the regex case-insensitive
+)!
+
+for path_obj in vlang_files.paths {
+    println(path_obj.path)
+}
+```
+
+#### 2. Controlling Recursion
+
+By default, `list()` is recursive. You can disable recursion to list only items in the current directory.
+
+```v
+import freeflowuniverse.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List only top-level files and directories (non-recursive)
+mut top_level_items := dir.list(
+    recursive: false
+)!
+
+for path_obj in top_level_items.paths {
+    println(path_obj.path)
+}
+```
+
+#### 3. Including or Excluding Hidden Files
+
+The `ignoredefault` parameter controls whether files and directories starting with `.` or `_` are ignored.
+
+```v
+import freeflowuniverse.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List all files and directories, including hidden ones
+mut all_items := dir.list(
+    ignoredefault: false
+)!
+
+for path_obj in all_items.paths {
+    println(path_obj.path)
+}
+```
+
+#### 4. Including Symbolic Links
+
+By default, symbolic links are ignored when walking the directory structure. Set `include_links` to `true` to include them.
+
+```v
+import freeflowuniverse.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List files and directories, including symbolic links
+mut items_with_links := dir.list(
+    include_links: true
+)!
+
+for path_obj in items_with_links.paths {
+    println(path_obj.path)
+}
+```
+
+#### 5. Listing Only Directories or Only Files
+
+Use `dirs_only` or `files_only` to restrict the results to only directories or only files.
+
+```v
+import freeflowuniverse.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List only directories (recursive)
+mut only_dirs := dir.list(
+    dirs_only: true
+)!
+
+// List only files (non-recursive)
+mut only_files := dir.list(
+    files_only: true,
+    recursive: false
+)!
+
+for path_obj in only_dirs.paths {
+    println(path_obj.path)
+}
+```
+
+By combining these parameters, you can create highly specific and powerful file system listing operations tailored to your needs.

+# Redisclient Module
+
+The `redisclient` module in Herolib provides a comprehensive client for interacting with Redis, supporting various commands, caching, queues, and RPC mechanisms.
+
+## Key Features
+
+-   **Direct Redis Commands**: Access to a wide range of Redis commands (strings, hashes, lists, keys, etc.).
+-   **Caching**: Built-in caching mechanism with namespace support and expiration.
+-   **Queues**: Simple queue implementation using Redis lists.
+-   **RPC**: Remote Procedure Call (RPC) functionality over Redis queues for inter-service communication.
+
+## Basic Usage
+
+To get a Redis client instance, use `redisclient.core_get()`. By default, it connects to `127.0.0.1:6379`. You can specify a different address and port using the `RedisURL` struct.
+
+```v
+import freeflowuniverse.herolib.core.redisclient
+
+// Connect to default Redis instance (127.0.0.1:6379)
+mut redis := redisclient.core_get()!
+
+// Or connect to a specific Redis instance
+// mut redis_url := redisclient.RedisURL{address: 'my.redis.server', port: 6380}
+// mut redis := redisclient.core_get(redis_url)!
+
+// Example: Set and Get a key
+redis.set('mykey', 'myvalue')!
+value := redis.get('mykey')!
+// assert value == 'myvalue'
+
+// Example: Check if a key exists
+exists := redis.exists('mykey')!
+// assert exists == true
+
+// Example: Delete a key
+redis.del('mykey')!
+```
+
+## Redis Commands
+
+The `Redis` object provides methods for most standard Redis commands. Here are some examples:
+
+### String Commands
+
+-   `set(key string, value string) !`: Sets the string value of a key.
+-   `get(key string) !string`: Gets the string value of a key.
+-   `set_ex(key string, value string, ex string) !`: Sets a key with an expiration time in seconds.
+-   `incr(key string) !int`: Increments the integer value of a key by one.
+-   `decr(key string) !int`: Decrements the integer value of a key by one.
+-   `append(key string, value string) !int`: Appends a value to a key.
+-   `strlen(key string) !int`: Gets the length of the value stored in a key.
+
+```v
+redis.set('counter', '10')!
+redis.incr('counter')! // counter is now 11
+val := redis.get('counter')! // "11"
+```
+
+### Hash Commands
+
+-   `hset(key string, skey string, value string) !`: Sets the string value of a hash field.
+-   `hget(key string, skey string) !string`: Gets the value of a hash field.
+-   `hgetall(key string) !map[string]string`: Gets all fields and values in a hash.
+-   `hexists(key string, skey string) !bool`: Checks if a hash field exists.
+-   `hdel(key string, skey string) !int`: Deletes one or more hash fields.
+
+```v
+redis.hset('user:1', 'name', 'John Doe')!
+redis.hset('user:1', 'email', 'john@example.com')!
+user_name := redis.hget('user:1', 'name')! // "John Doe"
+user_data := redis.hgetall('user:1')! // map['name':'John Doe', 'email':'john@example.com']
+```
+
+### List Commands
+
+-   `lpush(key string, element string) !int`: Inserts all specified values at the head of the list stored at key.
+-   `rpush(key string, element string) !int`: Inserts all specified values at the tail of the list stored at key.
+-   `lpop(key string) !string`: Removes and returns the first element of the list stored at key.
+-   `rpop(key string) !string`: Removes and returns the last element of the list stored at key.
+-   `llen(key string) !int`: Gets the length of a list.
+-   `lrange(key string, start int, end int) ![]resp.RValue`: Gets a range of elements from a list.
+
+```v
+redis.lpush('mylist', 'item1')!
+redis.rpush('mylist', 'item2')!
+first_item := redis.lpop('mylist')! // "item1"
+```
+
+### Set Commands
+
+-   `sadd(key string, members []string) !int`: Adds the specified members to the set stored at key.
+-   `smismember(key string, members []string) ![]int`: Returns if member is a member of the set stored at key.
+
+```v
+redis.sadd('myset', ['member1', 'member2'])!
+is_member := redis.smismember('myset', ['member1', 'member3'])! // [1, 0]
+```
+
+### Key Management
+
+-   `keys(pattern string) ![]string`: Finds all keys matching the given pattern.
+-   `del(key string) !int`: Deletes a key.
+-   `expire(key string, seconds int) !int`: Sets a key's time to live in seconds.

+-   `flushall() !`: Deletes all the keys of all the existing databases.
+-   `flushdb() !`: Deletes all the keys of the currently selected database.
+-   `selectdb(database int) !`: Changes the selected database.
+
+```v
+redis.set('temp_key', 'value')!
+redis.expire('temp_key', 60)! // Expires in 60 seconds
+```
+
+## Redis Cache
+
+The `RedisCache` struct provides a convenient way to implement caching using Redis.
+
+```v
+import freeflowuniverse.herolib.core.redisclient
+
+mut redis := redisclient.core_get()!
+mut cache := redis.cache('my_app_cache')
+
+// Set a value in cache with expiration (e.g., 3600 seconds)
+cache.set('user:profile:123', '{ "name": "Alice" }', 3600)!
+
+// Get a value from cache
+cached_data := cache.get('user:profile:123') or {
+    // Cache miss, fetch from source
+    println('Cache miss for user:profile:123')
+    return
+}
+// println('Cached data: ${cached_data}')
+
+// Check if a key exists in cache
+exists := cache.exists('user:profile:123')
+// assert exists == true
+
+// Reset the cache for the namespace
+cache.reset()!
+```
+
+## Redis Queue
+
+The `RedisQueue` struct provides a simple queue mechanism using Redis lists.
+
+```v
+import freeflowuniverse.herolib.core.redisclient
+import time
+
+mut redis := redisclient.core_get()!
+mut my_queue := redis.queue_get('my_task_queue')
+
+// Add items to the queue
+my_queue.add('task1')!
+my_queue.add('task2')!
+
+// Get an item from the queue with a timeout (e.g., 1000 milliseconds)
+task := my_queue.get(1000)!
+// assert task == 'task1'
+
+// Pop an item without timeout (returns error if no item)
+task2 := my_queue.pop()!
+// assert task2 == 'task2'
+```
+
+## Redis RPC
+
+The `RedisRpc` struct enables Remote Procedure Call (RPC) over Redis, allowing services to communicate by sending messages to queues and waiting for responses.
+
+```v
+import freeflowuniverse.herolib.core.redisclient
+import json
+import time
+
+mut redis := redisclient.core_get()!
+mut rpc_client := redis.rpc_get('my_rpc_service')
+
+// Define a function to process RPC requests (server-side)
+fn my_rpc_processor(cmd string, data string) !string {
+    // Simulate some processing based on cmd and data
+    return 'Processed: cmd=${cmd}, data=${data}'
+}
+
+// --- Client Side (calling the RPC) ---
+// Call the RPC service
+response := rpc_client.call(
+    cmd: 'greet',
+    data: '{"name": "World"}',
+    wait: true,
+    timeout: 5000 // 5 seconds timeout
+)!
+// println('RPC Response: ${response}')
+// assert response == 'Processed: cmd=greet, data={"name": "World"}'
+
+// --- Server Side (processing RPC requests) ---
+// In a separate goroutine or process, you would run:
+// rpc_client.process(my_rpc_processor, timeout: 0)! // timeout 0 means no timeout, keeps processing
+
+// Example of how to process a single request (for testing/demonstration)
+// In a real application, this would be in a loop or a background worker
+// return_queue_name := rpc_client.process(my_rpc_processor, timeout: 1000)!
+// result := rpc_client.result(1000, return_queue_name)!
+// println('Processed result: ${result}')

+# 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
+}
+```
+

+The `compress` module in V provides low-level functionalities for compressing and decompressing byte arrays.
+
+**Functions Overview (Low-Level):**
+
+*   **`compress(data []u8, flags int) ![]u8`**: Compresses an array of bytes.
+*   **`decompress(data []u8, flags int) ![]u8`**: Decompresses an array of bytes.
+*   **`decompress_with_callback(data []u8, cb ChunkCallback, userdata voidptr, flags int) !u64`**: Decompresses byte arrays using a callback function for chunks.
+
+**Type Definition (Low-Level):**
+
+*   **`ChunkCallback`**: A function type `fn (chunk []u8, userdata voidptr) int` used to receive decompressed chunks.
+
+---
+
+**`compress.gzip` Module (High-Level Gzip Operations):**
+
+For high-level gzip compression and decompression, use the `compress.gzip` module. This module provides a more convenient and recommended way to handle gzip operations compared to the low-level `compress` module.
+
+**Key Features of `compress.gzip`:**
+
+*   **`compress(data []u8, params CompressParams) ![]u8`**: Compresses data using gzip, allowing specification of `CompressParams` like `compression_level` (0-4095).
+*   **`decompress(data []u8, params DecompressParams) ![]u8`**: Decompresses gzip-compressed data, allowing specification of `DecompressParams` for verification.
+*   **`decompress_with_callback(data []u8, cb compr.ChunkCallback, userdata voidptr, params DecompressParams) !int`**: Decompresses gzip data with a callback for chunks, similar to the low-level version but for gzip streams.
+*   **`validate(data []u8, params DecompressParams) !GzipHeader`**: Validates a gzip header and returns its details.
+
+**Parameter Structures:**
+
+*   **`CompressParams`**: Configures compression, primarily `compression_level` (0-4095).
+*   **`DecompressParams`**: Configures decompression, including `verify_header_checksum`, `verify_length`, and `verify_checksum`.
+*   **`GzipHeader`**: Represents the structure of a gzip header.
+
+**Inline Code Example (Gzip Compression/Decompression):**
+
+```v
+import compress.gzip
+
+data := 'Hello, Gzip!'
+compressed := gzip.compress(data.bytes(), compression_level: 4095)!
+decompressed := gzip.decompress(compressed)!
+
+// Check if decompressed data matches original
+// if data.bytes() == decompressed { ... }
+```
+
+**Important Note:** Always prefer `compress.gzip` for general gzip compression/decompression tasks over the low-level `compress` module.
