Plugin that generates completion functions automatically from getopt-style help texts

zsh-completion-generator

Plugin that generates completion functions automatically from getopt-style help texts.

Motivation

Writing completion functions is boring, plus they can break when the software updates the CLI. This plugin tries to parse the help text of the given commands and generate a completion function automatically.

It's a best-effort service, not guaranteed to work in all cases. Completion functions which are already present (and most likely better) are not overridden by this plugin.

Manually

• Download the script or clone this repository:

  $ cd ~/.zsh/

  $ git clone git://github.com/RobSis/zsh-completion-generator.git

• Source the script before compinit in your ~/.zshrc:

  source $HOME/.zsh/zsh-completion-generator/zsh-completion-generator.plugin.zsh

  ...

  compinit

Custom zsh completion folder

If you want to use a different folder than the default one for completion files, you can export the GENCOMPL_FPATH variable before sourcing the plugin :

$ GENCOMPL_FPATH=$HOME/.zsh/complete
$ source $HOME/.zsh/zsh-completion-generator/zsh-completion-generator.plugin.zsh

Custom python version

If you want to use a specific Python interpreter name, you can export the GENCOMPL_PY variable before sourcing the plugin :

$ GENCOMPL_PY=python2
$ source $HOME/.zsh/zsh-completion-generator/zsh-completion-generator.plugin.zsh

How to use

Provide default program list by (example):

zstyle :plugin:zsh-completion-generator programs   ggrep tr cat

The plugin will create completions for those programs at load time, once. You can also generate completions from the shell, by using provided gencomp function:

$ gencomp ggrep
$ source ~/.zshrc # or run `compinit'
$ ggrep -*[TAB]* -> magic
