Currently I am trying to figure out how to automatically produce a changelog. The plan was to use the default branch and mark commits with a label as "delivered to customer" the Label should have the version number.
So I added 3 Labels (Version0,Version1,Version2) to branch "default". Now I want to generate a hg log for
"Current Tag" of branch=default to "Current Tag -1"
But .. I cant figure out the right syntax.
I tried things similar to:
hg log --branch=default --rev="tag()" --template=Changelog => no Error but no result
hg log --branch=default --rev="tag(Version0):tag(Version1)" --template=Changelog => Errors Version0 does not exist.
Can someone give/or point me to correct syntax. I would prefer a solution where I don't need to know the tag names.
Something like: Log for branch=default where from last to last -1 where Tag exists.
Optional: I found the "tag Part" also without --rev used like "tag()::tag()" but I cant figure out which part of hg Documentation (function name) I have to look into...
I'll show the whole process on local clone of hg-git repo with a lot of tags as version-numbers, but you have to read hg help revisions carefully after all.
Starting point (almost identical to your command)hg log -r "tag() & branch(default)" --style compact (output truncated for readability)

Revset is good, but string is too long and not-bulletproof for typing, polish it with revsetalias and after adding to .hgrc for repo into existing or created now [revsetalias] section something like
rcl = limit(reverse(tag() & branch(default)),1,1)::limit(reverse(tag() & branch(default)),1)
command hg log -r "rcl" --style compact will produce the same result as previous long version, but it's at least more compact and memorable
HTH
Some notes:
compacthg log ... command into new hg-alias and use it as (f.e) hg rcl
