Mercurial Log Templates - mercurial

Question

I have created a log alias in .hgrc file
nlog = glog --style=${HOME}/.hg-ext/templates.lg
Now in the templates.lg I use label function to colorize output
changeset = "{label('red',rev)} {label('c.author', author|person)} {desc|firstline|strip} {label('green', date|age)} {label('yellow', branches)}{label('yellow',bookmarks)}{label('yellow', tags)}\n\n"
changeset_verbose = "{label('red',rev)}:{node|short} {label('c.author',author|person)} {desc|firstline|strip} {label('green',date|age)} {label('yellow', branches)}{label('yellow',bookmarks)}{label('yellow', tags)}\n\n"
start_branches = " "
branch = "{label('yellow', branch)}"
start_bookmarks = " "
bookmark = "{label('yellow', bookmark)}, "
last_bookmark = "{label('yellow', bookmark}"
start_tags = " "
tag = "{label('yellow', tag)}, "
last_tag = "{label('yellow', tag)}"
When I run hg nlog it works ok on some repositories, but fails on others with follwing trace
C:\Users\esharapov\Repos\Composer.Hg>hg -v --traceback nlog

What could be the reason ?

Answer 1

I can't show you your mistake, but I performed some additional tests with strict correlations between condition and result
Preparation
Created $TortoiseHg\templates\map-cmdline.colorglog with content, identical to your templates.lg (I'm too lazy to write your long command on every test)
Found command-line in my 3.7.1, equivalent to your nlog (because hg: unknown command 'glog'): it's
hg log -G --style=colorglog
log -G and style without path, because style-file in default map-location with good name
Enabled Color Extension
Testing
Repo without tags (except mandatory tip) or bookmarks
>hg paths
default = https://bitbucket.org/albert_brand/hgexportfiles
>hg tags

>hg book
no bookmarks set
hg log - OK
Repo with tags and bookmarks
>hg paths
default = http://bitbucket.org/durin42/hg-git/

Additional tests with single tagged|bookmarked revisions in hg-git gepo

Tagged revision - OK
>hg log -r 490 --style=colorglog
hg: parse error at 26: unexpected token: end
Bookmarked revision - FAIL
ADDITION
OK, I catched it. As usual, obvious typo in obvious place. Instead of
last_bookmark = "{label('yellow', bookmark}"
it must be
last_bookmark = "{label('yellow', bookmark)}"
for obvious reason: label(), not label(
and bookmarked revision will not generate error anymore
