Introduce four new template keywords: {parent1}, {parent2}, {parent1node} and {parent2node}. The "node" flavors of these always show full 40 digit hashes, but users can get the short version with a filter construction like '{parent1node|short}'. diff -r c87ba0a6fb79 -r c25531ed58b0 mercurial/templatekw.py --- a/mercurial/templatekw.py Mon Aug 13 11:49:55 2012 -0700 +++ b/mercurial/templatekw.py Tue Jul 10 08:43:32 2012 -0700 @@ -275,6 +275,36 @@ """ return ctx.hex() +def showparent1(repo, ctx, templ, **args): + """:parent1: Integer.
