lazycomplete

Lazy loading for shell completion scripts.

A lot of programs provide their own shell completion script by invoking them with a specific argument like mybinary completion. The easiest way to use it is to add the call to the shell init script (like .bashrc) which keeps the completion up to date. Add a couple of these and shell startup time is affected considerably though as a single invocation and subsequent parsing can take ~50-100ms. This tool generates a lazy loading script for given binaries where the actual completion script is resolved only when needed.

Usage

Invoke with pairs of binary name and command to be invoked to create the completion:

# bash
source <(lazycomplete \
  example 'example _carapace' \
  lab 'lab _carapace' \
)

# elvish
eval (lazycomplete ^
  example 'example _carapace' ^
  lab 'lab _carapace' ^
|slurp)


# fish
lazycomplete \
  example 'example _carapace' \
  lab 'lab _carapace' \
| source

# oil
source <(lazycomplete \
  example 'example _carapace' \
  lab 'lab _carapace' \
)

# powershell
lazycomplete `
  example 'example _carapace' `
  lab 'lab _carapace' `
| Out-String | Invoke-Expression

# xonsh
exec($(lazycomplete \
  example 'example _carapace' \
  lab 'lab _carapace' \
))

# zsh
source <(lazycomplete \
  example 'example _carapace' \
  lab 'lab _carapace' \
)
