That makes me think they were only carried over from SVN. Bram,
when you push new patches, are you no longer adding the tags? It
would be beneficial. Having to inspect/grep the logs is a pretty
poor substitute for being able to do:
$ hg co v7-3-000
I haven't looked into this yet. Is there a simple way to apply a
tag to a specific hg changeset version, so that you can check out
that version by that tag?
$ hg tag -r [revision] [name]
e.g. the Vim 7.3.000 candidate(s?) named above
$ hg tag -r ee53a39d5896 v7-3-000
$ hg tag -r 2a2ad267db08 v7-3-000
I'm not going to type these commands, they need to be part of a
script. So how do we get that revision number for a patch version, or
the other way around: how do we get the version number from each
revision number? We actually need both, one for tagging existing
versions and one to tag each version when I commit a patch.
I already have a script that does "hg commit" with the description
taken from the patch. I would need to add something to that script to
tag the version. I suppose that can only be done after the commit?
Or can "hg commit" add a tag at the same time? The help doesn't
mention it.
I don't think you can do it in a single command, but tagging the
just-committed patch is easy. The [-r revision] argument is optional,
defaulting to tip (or you can specify [-r tip] explicitly). So:
$ [whatever commands to commit the patch]
$ tagname=v${major}-${minor}-${patch}
$ hg tag $tagname
That autocommits the tag. If that's undesirable for some reason
(aesthetics), the .hgtags file is of the format:
[commit sha-1] <space> [tag name] <nl>
So:
$ hg log -r tip --template "{node} $tagname\n" >> .hgtags
For the scripted portion of going back and adding all of the missing
tags (formatted for less unreadability -- ran it as a one-liner):
$ hg log --template '{node} {desc|firstline}\n' | \
: perl -lnwe 'next unless my ($rev, $major, $minor, $patch) = /^(\S+) updated
for version (7)\.([23])\.(\d\d\d)$/;
: my $tag = "v${major}-${minor}-${patch}";
: next if $seen{$tag};
: $seen{$tag}++;
: next if $minor == 2 and $patch <= 325;
: print "$rev $tag"' >> .hgtags
$ hg ci -m 'added missing tags'
I'll send it as an hg email in response to this message.
