Configuring git log to use mailmap by default

As of git 1.8.2, git log takes a --use-mailmap parameter to enable this behavior.

It appears that this isn't a feature, yet, due to hysterical raisins.

I have Git 2.4.1. If you set log.mailmap config to true, that will set it to work with git log also

git config --global log.mailmap true

You can set up defaults in your .gitconfig file. The documentation says:

log.mailmap

If true, makes git-log, git-show, and git-whatchanged assume --use-mailmap.

This will look for a .mailmap only in the root of the working tree.

To set:

git config --global log.mailmap true

Global mailmap file

mailmap.file

The location of an augmenting mailmap file. The default mailmap, located in the root of the repository, is loaded first, then the mailmap file pointed to by this variable. The location of the mailmap file may be in a repository subdirectory, or somewhere outside of the repository itself. See git-shortlog and git-blame.

To set:

git config --global mailmap.file ~/.mailmap

Advanced

You can also use a repository blob as a mailmap file, see mailmap.blob in the documentation linked to above.
