Git diff output to file preserve coloring

Question

Is it possible to do git diff and save the output to a file with the coloring somehow?

I know how to do git diff > filename.rtf - which saves to a file, but I'd like to preserve the coloring.

You can convert to html with color: http://stackoverflow.com/questions/2013091/coloured-diff-to-html — Gabe Moothart, Mar 14 '12 at 17:31
Notepad++ will highlight the file if you save it with the .diff extension. — Monsignor, Nov 05 '14 at 12:33

Try:

git diff --color > foo.txt

Then later issue:

cat foo.txt

Or:

less -R foo.txt

@RoR, one person's "gibberish" is another person's (well, terminal's) color codes. ;-) I tried it and it works; the coloring is preserved if I `cat` the file from the command-line. (How else would you expect the colors to be preserved?) – mpontillo Mar 14 '12 at 17:20

Well that's what it does. Adds bash coloring codes. If you cat the file in the console it shows the colors. – ralphtheninja Mar 14 '12 at 17:20

@RoR You'd have to put something in the middle there to convert the bash color codes to rtf format. – ralphtheninja Mar 14 '12 at 17:23

Notepad++ can highlight diff files. (*.diff extensions are automatically highlighted, otherwise change `Language --> D --> Diff`.) If you don't like default colors, change them in `Settings --> Style Configurator --> Diff`. To copy paste with colors you can use a plugin (e.g. `NppExport`) that allows exporting/copying into RTF or HTML. – Nikita R. Oct 22 '15 at 22:31

git diff A B > foo.diff (Many editors will open the file with the colors because the file is a .diff file) – zeusstl Mar 18 '16 at 13:12

Save the file with a .diff extension and open it in Notepad++ or Vim or SublimeText.

git diff > 20150203_someChanges.diff

Thanks @Monsingor

Open the output diff file in Sublime Text 2. It shows the diff colors.

You might need to change syntax to diff to enable proper highlighting in case the diff file has extension different from *.diff. (via View -> Syntax -> Diff). – Nikita R. Oct 22 '15 at 22:27
It doesn't highlight `diff.txt` for me, even with automatically detected "Diff" in the right bottom corner. – Nakilon Sep 20 '16 at 20:31

To expand on @Gabe's answer.

You can pipe the output to an ansi to html converter bash script and direct that output to an html file:

git diff --color|./ansi2html.sh > changes.html

of course html can be viewed by any browser so output can be read in Windows etc.

ansi2html code is here: http://www.pixelbeat.org/scripts/ansi2html.sh

Get Homebrew and run `brew install gawk`. You'll also need `brew install gnu-sed`. – Geoffrey Booth Oct 30 '15 at 19:53

The ansi2html python library did it for me https://github.com/ralphbean/ansi2html. pip installable and works exactly as the bash script in this answer. Don't forget to replace "./ansi2html.sh" with "ansi2html". – Nagasaki45 Feb 04 '20 at 00:13

I found an answer here: Color output of specific git command.

You can pass -c color.ui=always to any git command and it will keep coloring on redirection. For example: git -c color.ui=always status > file

git remote add -f b path/to/repo_b.git
git remote update
git diff master remotes/b/master > foo.txt

Differences extracted in '*.txt' files are easily read by SublimeText2 without the need to set (via View -> Syntax -> Diff).
