How to list a directory in a GIT account with the most recent validation information for each directory entry?

advertisements

I want to list a directory from a GIT repository together with the latest commit info of each directory entry. Similiar to how Github displays directories or how viewvc displays a directory in a SVN/CVS repo.

Currently I do it like this:

  1. Get the directory entries with git ls-tree master and parse the directory structure from the output.

  2. Then for each directory entry I do this: git log -n 1 master -- filename and parse the commit info from it (I specify a special format string to make this easier, but this isn't relevant to my problem)

It's pretty obvious that this is very slow because I have to call git for each file. Is there a faster way to do this? Maybe a single command I can execute to get all the data I need at once?


Oneliner to parse git whatchanged output and print tree annotated with recent commit ids:

git whatchanged -r --pretty=oneline | perl -ne 'our %q; if (/^([0-9a-f]{40})/) {$c = $1} if (/:.{38}(.*)/) { $q{$1} = $c unless exists $q{$1} }; END { print map {"$q{$_} $_\n"} (keys %q); }'  | sort -k 2

Example output:

You can adjust git whatchanged parameters and/or filter the output as you want.
