diffwc - diff + /w/ord highlighting + /c/olor
This document describes version 0.002 of diffwc (from Perl distribution App-diffwc), released on 2017-08-12.
Use as you would use diff (the coloring and word highlighting currently will only be shown if you use the unified format):
% diffwc -u file1 file2 % diffwc -ruN My-Dist-0.001 My-Dist-0.002
To alias diff to diffwc, in your shell startup file:
alias diff=diffwc
This is a wrapper for the GNU command-line utility diff. It adds word highlighting and colors (note that GNU diff 3.4 or later supports --color already).
--color
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C diffwc diffwc
in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
~/.bashrc
It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.
To activate tcsh completion for this script, put:
complete diffwc 'p/*/`diffwc`/'
in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
~/.tcshrc
It is also recommended to install shcompgen (see above).
shcompgen
For fish and zsh, install shcompgen as described above.

When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.
https://github.com/walles/riff, a Ruby-based utility by which this utility is inspired. riff is more git-oriented: it uses the same color scheme from git while diffwc comes with its own color schemes. riff comes only as a filter, while this package offers a diff wrapper (diffwc) as well as filter (diffwc-filter-u). riff currently has problems dealing with non-unified outputs or multiline word highlighting, and also it does not feel like a typical Unix utility to me (no manpages, for example), so I made diffwc instead.
diffwc-filter-u from the same package, in the form of diff output filter.
