pwsh-diff

This project has been "soft-abandoned," because it turns out (perhaps unsurprisingly) that less-for-Windows has the same limitations as Perl-for-Windows with respect to color control codes, and there are really no other suitable pagers. I would consider resuming work on this, were a decent Windows-native pager to appear; if you know something I don't, please open an issue!

pwsh-diff aims to serve as a PowerShell-based alternative to diff-highlight (and, eventually, diff-so-fancy) on Windows, because Perl and Windows don't seem to get along when it comes to ANSI coloring.

Installation

Make sure you have PowerShell Core (pwsh.exe) in your PATH somewhere. Then, copy the pwsh-diff script to a directory in your PATH. That's it!

Usage

Configure Git to use pwsh-git for all diff/log output:

git config --global core.pager "pwsh-diff | less --tabs=4 -RFX"

Improved colors

pwsh-diff will read the same color settings expected by diff-highlight, and it depends on Git itself to colorize everything besides the lines with highlighted bits. The following options are recommended:

git config --global color.ui true

git config --global color.diff-highlight.oldNormal    "red bold"
git config --global color.diff-highlight.oldHighlight "red bold 52"
git config --global color.diff-highlight.newNormal    "green bold"
git config --global color.diff-highlight.newHighlight "green bold 22"

git config --global color.diff.old "red bold"
git config --global color.diff.new "green bold"

Acknowledgements

Much of the requisite logic has been adapted directly from the aforementioned diff-highlight and diff-so-fancy.
