pyagfs 0.1.4

Python SDK for AGFS (Pluggable File System) Server

pyagfs - AGFS Python SDK

Python SDK for interacting with AGFS (Plugin-based File System) Server API.

See more details at c4pt0r/agfs

Installation

pip install pyagfs

For local development:

pip install -e .

Quick Start

from pyagfs import AGFSClient

# Initialize client
client = AGFSClient("http://localhost:8080")

# Check server health
health = client.health()
print(health)

# List directory contents
files = client.ls("/")
for file in files:
    print(f"{file['name']} - {'dir' if file['isDir'] else 'file'}")

# Read file content
content = client.cat("/path/to/file.txt")
print(content.decode())

# Write to file
client.write("/path/to/file.txt", b"Hello, AGFS!")

# Create directory
client.mkdir("/new/directory")

# Remove file or directory
client.rm("/path/to/file.txt")
client.rm("/path/to/directory", recursive=True)

Advanced Usage

Streaming Operations

# Stream file content
response = client.cat("/large/file.log", stream=True)
for chunk in response.iter_content(chunk_size=8192):
    process(chunk)

# Stream grep results
for match in client.grep("/logs", "error", recursive=True, stream=True):
    if match.get('type') == 'summary':
        print(f"Total matches: {match['count']}")
    else:
        print(f"{match['file']}:{match['line']}: {match['content']}")

Mount Management

# List mounted plugins
mounts = client.mounts()

# Mount a plugin
client.mount("memfs", "/test/mem", {})
client.mount("sqlfs", "/test/db", {
    "backend": "sqlite",
    "db_path": "/tmp/test.db"
})

# Unmount a plugin
client.unmount("/test/mem")

Plugin Management

# Load external plugin
result = client.load_plugin("./plugins/myplugin.so")
print(result)

# List loaded plugins
plugins = client.list_plugins()
print(plugins)

# Unload plugin
client.unload_plugin("./plugins/myplugin.so")

Search with Grep

# Simple search
result = client.grep("/local/logs", "error")
print(f"Found {result['count']} matches")
for match in result['matches']:
    print(f"{match['file']}:{match['line']}: {match['content']}")

# Recursive case-insensitive search
result = client.grep("/local", "warning|error", recursive=True, case_insensitive=True)

File Operations

# Get file info
info = client.stat("/path/to/file.txt")
print(f"Size: {info['size']}, Mode: {info['mode']}")

# Move/rename file
client.mv("/old/path.txt", "/new/path.txt")

# Change permissions
client.chmod("/path/to/file.txt", 0o644)

# Copy file (read + write)
content = client.cat("/source.txt")
client.write("/destination.txt", content)

Error Handling

from pyagfs import AGFSClient, AGFSClientError

try:
    client = AGFSClient("http://localhost:8080")
    content = client.cat("/nonexistent/file.txt")
except AGFSClientError as e:
    print(f"Error: {e}")

API Reference

AGFSClient

Constructor

• AGFSClient(api_base_url, timeout=10) - Initialize client with API base URL

File Operations

• ls(path="/") - List directory contents
• cat(path, offset=0, size=-1, stream=False) - Read file content
• write(path, data) - Write data to file
• create(path) - Create new empty file
• rm(path, recursive=False) - Remove file or directory
• stat(path) - Get file/directory information
• mv(old_path, new_path) - Move/rename file or directory
• chmod(path, mode) - Change file permissions

Directory Operations

• mkdir(path, mode="755") - Create directory

Search Operations

• grep(path, pattern, recursive=False, case_insensitive=False, stream=False) - Search for pattern in files

Mount Operations

• mounts() - List all mounted plugins
• mount(fstype, path, config) - Mount a plugin dynamically
• unmount(path) - Unmount a plugin

Plugin Operations

• list_plugins() - List all loaded external plugins
• load_plugin(library_path) - Load an external plugin
• unload_plugin(library_path) - Unload an external plugin

Health Check

• health() - Check server health
