mgalgs/fuzzy_bash_completion

Intro

This bash completion module performs "fuzzy" matching similar to textmate's "Go to File" fuzzy matching, "flex matching" in emacs' ido mode, etc.

For example:

mkdir pizza
mkdir jazz
cd zz<TAB>
# displays `pizza' and `jazz'
rm -r jazz
cd zz<TAB>
# completes the word `pizza'

Requirements

bash >= 4.0 (since we need associative arrays).
The bash-completion package (could have a different name on your distro). Please follow the instructions specific to your distro for installing and enabling bash-completion.

Usage

Put the following in your ~/.inputrc:

set show-all-if-ambiguous on

Put the following in your ~/.bashrc:

source /path/to/fuzzy_bash_completion

Now you can start enabling fuzzy completion for individual commands like so:

fuzzy_setup_for_command cd

Either interactively or by adding it to your ~/.bashrc.

There are a few helper functions to set up fuzzy completion for known commands in bulk. However, these helper functions only work on certain versions of bash completion, so YMMV.

fuzzy_replace_filedir_xspec

To list all commands currently using fuzzy completion, run:

fuzzy_list_replaced_specs

Troubleshooting

List commands that are currently fuzzy

You can list all of the fuzzy compspecs with:

fuzzy_list_replaced_specs

Revert back to original completion specs (debugging and development)

If something doesn't seem right and you want to back out all fuzzy completion, you can use:

fuzzy_restore_all_specs

(and you should also file a bug report on GitHub)

Known issues, Quirks, etc

Doesn't yet play nicely with default bash completion for variable names.
