zsh-completion-generator

Generating zsh completion function from getopt-style help text.

Motivation

Writing completion functions is boring, plus they deprecate when the software updates the CLI. This plugin tries to read the list of options from the help text of the program and generate a completion function automatically.

It's a best-effort service, not guaranteed to work in all cases. Completion functions already defined (and are therefore more thought out) are not overridden by this plugin.
