ngenctl 0.1.13

Universal command wrapper package that dispatches to /usr/local/bin/ngenctl-* scripts

ngenctl

Universal command wrapper package that dispatches to /usr/local/bin/ngenctl-* scripts, environment commands, and supports aliases for quick access.

Installation

Install from PyPI:

pip install ngenctl

Or install from source:

pip install .

Note: Installation to /usr/local/bin requires sudo/root permissions. The package will automatically install bundled scripts to /usr/local/bin/ngenctl-* during installation.

Usage

The ngenctl command provides a unified interface for executing:

• Scripts from /usr/local/bin/ngenctl-{command}
• Environment commands available in PATH (configured via config.json)
• Aliases for quick command shortcuts (configured via alias.json)

Command Resolution Priority

1. Aliases - Commands defined in $HOME/.ngenctl/alias.json
2. Scripts - Scripts from /usr/local/bin/ngenctl-{command} or bundled scripts
3. Environment Commands - Commands from $HOME/.ngenctl/config.json available in PATH

Examples

Scripts

If you have a script at /usr/local/bin/ngenctl-rancher, you can use it as:

ngenctl rancher --help
ngenctl rancher version

Aliases

Create aliases in $HOME/.ngenctl/alias.json:

{
  "login": "rancher login",
  "clusters": "rancher clusters",
  "ci": "devops-ci",
  "gn": "kubectl get nodes"
}

Then use the aliases:

ngenctl login           # Executes: ngenctl rancher login
ngenctl clusters        # Executes: ngenctl rancher clusters
ngenctl ci saas-app develop  # Executes: ngenctl devops-ci saas-app develop
ngenctl gn              # Executes: ngenctl kubectl get nodes

Environment Commands

Configure environment commands in $HOME/.ngenctl/config.json:

{
  "doq": "doq",
  "kubectl": "kubectl"
}

Then use them directly:

ngenctl doq ns develop-saas    # Executes: doq ns develop-saas
ngenctl kubectl get nodes      # Executes: kubectl get nodes

How It Works

1. When you run ngenctl {command}, the CLI dispatcher checks in this order:
   • Aliases: Checks if the command is defined in $HOME/.ngenctl/alias.json and resolves it
   • Scripts: Looks for a script at /usr/local/bin/ngenctl-{command} or bundled scripts
   • Environment Commands: Checks $HOME/.ngenctl/config.json and verifies the command is available in PATH
2. If found, it executes the command with any additional arguments passed
3. Scripts can be any executable file (bash, sh, Python, or binary)
4. Aliases support recursive resolution and circular reference detection

Configuration

Aliases ($HOME/.ngenctl/alias.json)

Create command aliases to shorten frequently used commands:

{
  "login": "rancher login",
  "clusters": "rancher clusters",
  "ci": "devops-ci",
  "gn": "kubectl get nodes"
}

Aliases can reference other commands (scripts, environment commands, or other aliases). Circular references are automatically detected.

Environment Commands ($HOME/.ngenctl/config.json)

Map ngenctl commands to executables available in your PATH:

{
  "doq": "doq",
  "kubectl": "kubectl",
  "docker": "docker"
}

Commands in config.json will only work if the actual executable is available in your PATH.

Adding New Commands

Method 1: Scripts

1. Place a script at /usr/local/bin/ngenctl-{your-command}
2. Make sure it's executable: chmod +x /usr/local/bin/ngenctl-{your-command}
3. Use it with: ngenctl {your-command}

Method 2: Aliases

1. Edit $HOME/.ngenctl/alias.json
2. Add your alias: "{short-name}": "{full-command}"
3. Use it with: ngenctl {short-name}

Example:

{
  "login": "rancher login"
}

Then use: ngenctl login

Method 3: Environment Commands

1. Edit $HOME/.ngenctl/config.json
2. Add your command: "{ngenctl-command}": "{actual-command-in-path}"
3. Ensure the actual command is available in your PATH
4. Use it with: ngenctl {ngenctl-command}

Example:

{
  "doq": "doq"
}

Then use: ngenctl doq (if doq is in PATH)
