cli/cmd/core.go

// Package cmd implements the core CLI application.
//
// The CLI provides commands for:
//   - Multi-repo development workflows (dev)
//   - AI agent task management (ai)
//   - Go and PHP development tools (go, php)
//   - Build and release automation (build, ci)
//   - SDK validation and API compatibility (sdk)
//   - Package and environment management (pkg, vm)
//   - Documentation and testing (docs, test)
//   - Environment health checks (doctor)
//   - Repository setup and cloning (setup)
//
// Two build variants exist:
//   - Default build: Full development toolset
//   - CI build (-tags ci): Minimal release toolset

To load completions:

Bash:
  $ source <(core completion bash)

  # To load completions for each session, execute once:
  # Linux:
  $ core completion bash > /etc/bash_completion.d/core
  # macOS:
  $ core completion bash > $(brew --prefix)/etc/bash_completion.d/core

Zsh:
  # If shell completion is not already enabled in your environment,
  # you will need to enable it. You can execute the following once:
  $ echo "autoload -U compinit; compinit" >> ~/.zshrc

  # To load completions for each session, execute once:
  $ core completion zsh > "${fpath[1]}/_core"

  # You will need to start a new shell for this setup to take effect.

Fish:
  $ core completion fish | source

  # To load completions for each session, execute once:
  $ core completion fish > ~/.config/fish/completions/core.fish

PowerShell:
  PS> core completion powershell | Out-String | Invoke-Expression

  # To load completions for every new session, run:
  PS> core completion powershell > core.ps1
  # and source this file from your PowerShell profile.
