K4SH Plugins: Extending the Lightweight Shell Framework

Step 1: Create directory

mkdir -p ~/.k4sh/plugins/myplugin

7. Security Guidelines for Plugin Usage

• Only install plugins from trusted sources – they run with your shell’s privileges.
• Use k4sh plugin audit <plugin_name> to review system calls and file access.
• Run untrusted plugins inside the k4sh sandbox mode:

  k4sh --sandbox
  

• Plugins can be signed with GPG; verify with:

  k4sh plugin verify <plugin_name>
  

5. Plugin API (Core Hooks)

| Hook | Trigger | Use Case | |------|---------|----------| | on_load | After plugin loads | Initialize variables, check deps | | on_unload | Before removal | Cleanup temp files | | pre_exec | Before any command | Logging, access control | | post_exec | After command runs | Output parsing, notifications | | on_output | When output is generated | Redact secrets, format results |

Example hook:

function k4sh_hook_post_exec() 
    local cmd=$1
    local exit_code=$2
    if [[ $exit_code -ne 0 ]]; then
        echo "[!] Command '$cmd' failed" >> /var/log/k4sh_errors.log
    fi

1. k4sh/context-switcher

Switch between project profiles (env vars + aliases) instantly. k4sh plugins

k4sh use backend-dev   # loads node 18, sets AWS_PROFILE
k4sh use frontend      # loads node 20, sets VITE_ envs

Why k4sh Plugins Matter More Than Built-in Features

Most competing platforms (like TradingView or MetaTrader) offer "built-in" tools. These are often rigid, slow to update, and cannot be tailored to individual strategies. k4sh plugins flip this model on its head.

Advantages of using k4sh plugins:

1. Modularity: Install only what you need. No bloat, no unnecessary CPU cycles.
2. Community-Driven Innovation: The best k4sh plugins are open-source, peer-reviewed, and constantly updated by veteran traders.
3. Customization: You can modify a plugin’s source code to fit your exact risk parameters.
4. Performance: Plugins run natively within k4sh’s lightweight thread pool, avoiding the overhead of separate applications.

What is k4sh? (A Quick Refresher)

Before we explore the ecosystem of plugins, let us briefly revisit k4sh. Unlike monolithic trading platforms that come bloated with features you will never use, k4sh is a lean, command-line-friendly framework designed for real-time data processing. Its core provides:

• Low-latency event handling
• WebSocket and REST API bridges
• Basic order book management
• Scriptable automation hooks

But a skeleton alone cannot run a marathon. The true power is unlocked when you install k4sh plugins that add specific, optimized capabilities to this core. K4SH Plugins: Extending the Lightweight Shell Framework Step

Step 4: Load plugin

Building Your Own Custom k4sh Plugin

The open architecture means you are not limited to existing tools. Building a custom k4sh plugin is a weekend project for any intermediate developer.
