# 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.

## Status

WIP

## Usage

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

```sh

# 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' \

)

```
