Git Recipes

Categories: [ IT/Git ]

Here are a few recipes I use with git.

Using git log

Show which files have been modified by the commits: git log --name-status

View the successive changes for a given file: git log -p -- my_file (latest change first)

View the changes at word-level instead of line-level: git log --color-words

Make --color-words more readable with LaTeX files: add *.tex diff=tex to the repository's .git/info/attributes or to your $HOME/.gitattributes (read man gitattributes for more info on this, it supports other languages too)

Browseable Web Repository

To make an online, browsable web repository on a web server (I assume you have ssh access to it).

On the server, run:
$ mkdir some_directory
$ cd some_directory
$ git init
$ git config receive.denyCurrentBranch ignore
$ cat > .git/hooks/post-receive <<EOF
#!/bin/sh
GIT_WORK_TREE=.. git checkout -f
GIT_WORK_TREE=.. git update-server-info --force
EOF
$ chmod a+x .git/hooks/post-receive
The in the source repository, run:
$ git remote add web username@my.web.server:path/to/some_directory/.git
$ git push web master

(“username”, “my.web.server” and “path/to/” are exactly what you think they are.) Note the “.git” at the end of the path, it has to be there because git push is going to send its data into that directory.

When you run git push web master to upload the content of the source repository to the web repository, the post-receive hook checks out the latest version. The next time, you don't need to specify the “master” branch any more, simply running git push web is enough.
