# HG changeset patch # User Matt Harbison <matt_harbison@yahoo.com> # Date 1440360913 14400 # Sun Aug 23 16:15:13 2015 -0400 # Node ID 7635dd2e59810eaf75efdd5ba095b2c74f1e36f2 # Parent d315fc51e187c70ee75964f7503b8780f1c95884 templater: introduce latesttag() function to match a pattern (issue4184) This still requires the first patch from the previous version of this series. Unlike the last series, this allows the tags, changessincelasttag and latesttagdistance to be handled by this one function. A couple of issues I've noticed, and can't figure out. 1) "{latesttag('re:^t[13]$')}" crashes. It would be nice if there was a way to get it to show a list of tags in the same way {latesttags} does, as that's probably what most people would expect.

I applied a bogus '3.4.5' tag to '3.4.2' in the hg repo. This is the result: $ ../hg log -r tip \ -T "{latesttag('re:^\d\.\d\.\d$') % '{tags % \"{tag}, \"}, {distance}, {changes}\n'}" 3.4.23.4.5, 336, 1105 However, if 'tags' in makemap is replaced with the commented out code instead of just 'v[2]', it crashes: File "c:\Users\Matt\Projects\hg\mercurial\commands.py", line 4652, in log displayer.show(ctx, copies=copies, matchfn=revmatchfn) File "c:\Users\Matt\Projects\hg\mercurial\cmdutil.py", line 1148, in show self._show(ctx, copies, matchfn, props) File "c:\Users\Matt\Projects\hg\mercurial\cmdutil.py", line 1473, in _show self.ui.write(templater.stringify(self.t(key, **props))) File "c:\Users\Matt\Projects\hg\mercurial\templatefilters.py", line 346, in stringify return "".join([stringify(t) for t in thing if t is not None]) File "c:\Users\Matt\Projects\hg\mercurial\util.py", line 613, in increasingchunks for chunk in source: File "c:\Users\Matt\Projects\hg\mercurial\templater.py", line 762, in _flatten for j in _flatten(i): File "c:\Users\Matt\Projects\hg\mercurial\templater.py", line 762, in _flatten for j in _flatten(i): File "c:\Users\Matt\Projects\hg\mercurial\templater.py", line 762, in _flatten for j in _flatten(i): File "c:\Users\Matt\Projects\hg\mercurial\templater.py", line 755, in _flatten for i in thing: File "c:\Users\Matt\Projects\hg\mercurial\templater.py", line 284, in runmap d = func(context, mapping, data) File "c:\Users\Matt\Projects\hg\mercurial\templater.py", line 240, in runsymbol return v(**mapping) TypeError: __call__() got an unexpected keyword argument 'node' 3) The date is not the date the tag was applied, but the date of the commit that is tagged. I'm not sure that the date is particularly useful, so I have no problem leaving it out.
