Toast is a Python-based CLI utility with a plugin architecture that simplifies the use of CLI tools for AWS, Kubernetes, Git, and more.

Key Features

• Plugin-based architecture for easy extensibility
• Dynamic command discovery and loading
• AWS Features
  • AWS Profile Management (toast env)
  • AWS Region Management (toast region)
  • IAM Identity Checking (toast am)
• Kubernetes Features
  • Context Switching (toast ctx)
• Workspace Features
  • Directory Navigation (toast cdw)
• Other Utilities
  • System Update (toast update)
  • AWS SSM Commands (toast ssm)

Plugin Architecture

Toast uses a plugin-based architecture powered by Python's importlib and pkgutil modules:

• Each command is implemented as a separate plugin
• Plugins are automatically discovered and loaded at runtime
• New functionality can be added without modifying existing code

See ARCHITECTURE.md for detailed information about the design.

Installation

Requirements

• Python 3.6+
• Click package
• Python-dotenv package
• External tools used by various plugins:
  • fzf: Interactive selection in terminal
  • jq: JSON processing for formatted output
  • aws-cli: AWS command line interface
  • kubectl: Kubernetes command line tool

Installation Methods

# Install from PyPI
pip install toast-cli

# Update to latest version
pip install --upgrade toast-cli

# Install specific version
pip install toast-cli==3.0.0

# Install development version from GitHub
pip install git+https://github.com/opspresso/toast-cli.git

# Install in development mode from local clone
git clone https://github.com/opspresso/toast-cli.git
cd toast-cli
pip install -e .

Creating Symbolic Link (Optional)

If toast command is not available in your PATH after installation:

# Create a symbolic link to make it available system-wide
sudo ln -sf $(which toast) /usr/local/bin/toast

Usage

# View available commands
toast --help

# Run a specific command
toast am           # Show AWS identity
toast cdw          # Navigate workspace directories
toast ctx          # Manage Kubernetes contexts
toast env          # Set environment
toast region       # Set AWS region
toast ssm          # Run AWS SSM commands
toast update       # Update CLI tool

Extending with Plugins

To add a new plugin:

1. Create a new Python file in the plugins directory
2. Define a class that extends BasePlugin
3. Implement the required methods (execute and optionally get_arguments)
4. Set the name and help class variables

Example plugin:

from plugins.base_plugin import BasePlugin
import click

class MyPlugin(BasePlugin):
    name = "mycommand"
    help = "Description of my command"

    @classmethod
    def execute(cls, **kwargs):
        click.echo("My custom command execution")

Aliases

alias t='toast'

# Directory Navigation
c() {
  cd "$(toast cdw)"
}

# Common Command Aliases
alias i='toast am'      # Check AWS IAM info
alias e='toast env'     # Set AWS profile
alias r='toast region'  # Set AWS region
alias x='toast ctx'     # Switch Kubernetes context
