git-commit —显示更多上下文

Question

When doing a git commit git will open up $GIT_EDITOR for you to enter a commit message, with the diffs shown below.

Is there a way of configuring git so that it shows more context in the diffs? I'm thinking of something similar to grep's -C option, for showing more context in search results.

Reading git-commit's manpage didn't enlighten me.

Answer 1

Reading showing more context in git add provided the solution. Run the following command to provide 5 lines of context:

git config --global diff.context 5
