Git how to save a preset git log --format

Question

I really like the short git log format where I can see author, date and change description like this:

git log --pretty=format:"%h%x09%an%x09%ad%x09%s" 

Which outputs:

  fbc3503 mads    Thu Dec 4 07:43:27 2008 +0000   show mobile if phone is null...      ec36490 jesper  Wed Nov 26 05:41:37 2008 +0000  Cleanup after [942]: Using timezon   ae62afd tobias  Tue Nov 25 21:42:55 2008 +0000  Fixed #67 by adding time zone supp   164be7e mads    Tue Nov 25 19:56:43 2008 +0000  fixed tests, and a 'unending appoi 

(from stackoverflow question "link text")

Now, the question is, how do I save this as a new format on my machine so I only have to write something like, for instance:

git log --format=jespers_favourite 

Answer 1

In newer versions of Git (confirmed with v1.7.8) it is possible to set named pretty-print log formats using git config pretty.named_format. These can be set at a machine-wide, user or file level with the <file-option> argument.

To create a log format called jespers_favourite or the whole machine use --system

git config --system pretty.jespers_favourite "%h%x09%an%x09%ad%x09%s" 

For single user use '--global'

git config --global pretty.jespers_favourite "%h%x09%an%x09%ad%x09%s" 

Leaving the <file-option> argument blank will default to setting the config file of the current repository, .git/config unless defined otherwise.

Considering the git log manual page mentions:

--pretty[=<format>] --format[=<format>] 

Pretty-print the contents of the commit logs in a given format, where can be one of oneline, short, medium, full, fuller, email, raw and format:. When omitted, the format defaults to medium.

the <format> can only have predefined values.
That only leaves you the possibility to define an alias as a shortcut for that command.

[alias]         jespers_favourite = log --pretty=format:"%h%x09%an%x09%ad%x09%s" 

or

[alias]         compactlog = log --pretty=format:"%h%x09%an%x09%ad%x09%s"
