Purpose
completion generates a completion script for one supported shell. The shell
is a subcommand: bash, zsh, fish, or powershell.
Input and output
The required positional input is one supported shell. Script bytes go to
stdout; command failures go to stderr. --no-descriptions produces a smaller
script without help text.
Examples
Load completion for the current zsh session:
source <(margo completion zsh)
Generate scripts for distribution or inspection:
margo completion bash --no-descriptions > build/margo.bash
margo completion zsh --no-descriptions > build/_margo
margo completion fish --no-descriptions > build/margo.fish
margo completion powershell --no-descriptions > build/margo.ps1
Failures and diagnostics
An unsupported shell or invalid option exits 1 and writes Cobra's diagnostic
to stderr. Use margo completion SHELL --help for that shell's supported
installation paths and loading instructions.
Limitations and care
Generation does not edit shell startup files automatically. Redirect the output to a location appropriate for the target shell, or source it explicitly for the current session.
