[PATCH] Using monotone-viz/git-viz with mercurial -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [PATCH] Using monotone-viz/git-viz with mercurial From: Vincent Danjean <vdanjean.ml@free.fr> monotone-viz is a small GTK+ application that visualizes monotone ancestry graphs. Its home page is: http://oandrieu.nerim.net/monotone-viz/ As monotone and git are similar, the author adapted the 0.9 version to display git ancestry graphs and call it git-viz. I cannot see any link from the homepage, but looking in the archive of git ML, it can be found here: http://oandrieu.nerim.net/monotone-viz/git-viz-0.1.tar.gz I few days ago, I adapted it so that it works with the last versions of git/cogito. Patches and package are available here: http://dept-info.labri.fr/~danjean/deb.html#git-viz Today, I patched hgit so that it respects the output of git-diff-tree, I added git-{diff-tree,cat-file,rev-list,rev-tree} that call hgit (2 lines scripts), and added the script 'hg-viz'. hg-viz create a .git directory and store the SHA1 of the tip in .git/HEAD and then call my git-viz. All these modifications are in the attached patch. I try it in the mercurial repository. After applying the patch, you just have to add the contrib directory in your PATH and call hg-viz. An example of what we can see is on my web page (probably not for a long time) : http://dept-info.labri.fr/~danjean/temp/hg-viz.png Vincent -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCuM50ywK+sNU5EO8RAtlvAJ425JJI9chCdSi8D+R2Af/vJEOUpACffC9e fxjJ3umBkffj5g86jWaRGZ0= =LwA2 -----END PGP SIGNATURE-----
