A simple plugin integrating so-fancy/diff-so-fancy into Zsh. It provides:

• git dsf: A subcommand to run Git diffs through diff-so-fancy
• fancy-diff: A helper to run a unified diff and beautify it with diff-so-fancy

1. Install diff-so-fancy or load it via your preferred method.
2. Load the plugin in your .zshrc or plugin manager:

   # Example using Zi
   zi ice as'program' pick'bin/*'
   zi light z-shell/zsh-diff-so-fancy

3. Use the commands:
   • git dsf <files> to see a diff rendered by diff-so-fancy
   • fancy-diff <file1> <file2> to compare two files with diff-so-fancy

You can customize the less options by setting these environment variables in your .zshrc before loading the plugin:

# Customize less options for fancy-diff
export FANCY_DIFF_LESS_OPTS="--tabs=2 -RFX"

# Customize less options for git dsf
export GIT_DSF_LESS_OPTS="--tabs=2 -FRXS"

The default is --tabs=4 -FRXSi for both commands if not specified.

diff-so-fancy --colors        # Show recommended color config
diff-so-fancy --set-defaults  # Configure Git to use diff-so-fancy with suggested colors
diff-so-fancy --patch         # Patch mode, interoperable with `git add --patch`

# Use diff-so-fancy for all diffs
git config --global core.pager "diff-so-fancy | less --tabs=4 -RFX"

# Use diff-so-fancy for `git add --patch`
git config --global interactive.diffFilter "diff-so-fancy --patch"

• markEmptyLines (bool, default: true) Color the first block of an empty line.
• changeHunkIndicators (bool, default: true) Simplify Git header chunks to a more readable format.
• stripLeadingSymbols (bool, default: true) Remove leading + or - from lines.
• useUnicodeRuler (bool, default: true) Use Unicode line-drawing characters for file headers (disable if your terminal cannot display them).
• rulerWidth (int, default: full width) Set a fixed width for the file header separator.

• Both fancy-diff and git-dsf use the --patch flag with diff-so-fancy to preserve the original diff format in the output, which is useful for interoperability with tools that parse diff output.
• The plugin follows the Zsh Plugin Standard and provides an unload function for plugin managers that support unloading.
• The plugin checks if diff-so-fancy is installed and provides a helpful warning if it's not found.

zi ice as'null' sbin'bin/*'
zi light z-shell/zsh-diff-so-fancy

Or:

zi ice as'program' pick'bin/*'
zi light z-shell/zsh-diff-so-fancy

This places diff-so-fancy, fancy-diff, and git-dsf in $PATH, adding the dsf subcommand to Git automatically.
