gitfilters

Some smudge-and-clean filters for Git working directories.

Converts keywords of the form $Id$ in source files in Git working directories to Subversion-like revision/time/author strings.

Example of the effect of svnid.smudge.pl:

$Id: doc/makefile 9e2eb0a 2017-08-29 16:45:57Z Alan U. Kennington $

1. The subversion-style file name makefile is replaced by a relative path doc/makefile.
2. The subversion-style revision number is replaced by a short commit-hash 9e2eb0a because Git does not have revision numbers.
3. The UTC date and time are the same as in Subversion.
4. The author name is used instead of the Subversion-style Unix account username.

Note that Subversion expands keywords whenever you do a commit, but Git only runs smudge filters when you do a checkout. So if you want the keywork expansion to reflect the commit-hash and commit-time of the latest commit, you must force a checkout, for example by running the "touch" command on the recently committed files and then running git checkout on those files.
