backend.ai-cli 26.4.4rc2

Backend.AI Command Line Interface Helper

backend.ai-cli

Unified command-line interface for Backend.AI

How to adopt in CLI-enabled Backend.AI packages

An example setup.cfg in Backend.AI Manager:

[options.entry_points]
backendai_cli_v10 =
    mgr = ai.backend.manager.cli.__main__:main
    mgr.start-server = ai.backend.gateway.server:main

Define your package entry points that returns a Click command group using a prefix, and add additional entry points that returns a Click command using a prefix followed by a dot and sub-command name for shortcut access, under the backendai_cli_v10 entry point group.

Then add backend.ai-cli to the install_requires list.

You can do the same in setup.py as well.

Shell Tab Completion

The CLI provides built-in shell tab completion support for bash, zsh, and fish shells.

Quick Setup

# Show completion setup instructions
backend.ai completion --show

# Install completion automatically
backend.ai completion --shell bash  # Install to ~/.bashrc
backend.ai completion --shell zsh   # Install to ~/.zshrc
backend.ai completion --shell fish  # Install to fish completions

Manual Setup

If you prefer manual setup, you can add completion to your shell configuration:

Bash (~/.bashrc):

eval "$(_BACKEND_AI_COMPLETE=bash_source backend.ai)"

Zsh (~/.zshrc):

eval "$(_BACKEND_AI_COMPLETE=zsh_source backend.ai)"

Fish (~/.config/fish/config.fish):

backend.ai completion --shell fish | source

Features

Tab completion supports:

• Commands: All available commands and subcommands
• Options: Short and long flags with descriptions
• Arguments: Context-aware argument completion where applicable
• Help: Descriptions for commands and options

backend.ai --<TAB>            # Show global options
