templater: add optional timezone argument to localdate()
The keyword extension uses "utcdate" for a different function, so we can't
add new "utcdate" filter or function. Instead, this patch extends "localdate"
to a general timezone converter.

Mercurial allows you to customize output of commands through templates. You can either pass in a template or select an existing template-style from the command line, via the --template option. You can customize output for any "log-like" command: log, outgoing, incoming, tip, parents, and heads. Some built-in styles are packaged with Mercurial. These can be listed with :hg:`log --template list`. Example usage:: $ hg log -r1.0::1.1 --template changelog A template is a piece of text, with markup to invoke variable expansion:: $ hg log -r1 --template "{node}\n" b56ce7b07c52de7d5fd79fb89701ea538af65746 Strings in curly braces are called keywords. The availability of keywords depends on the exact context of the templater. These keywords are usually available for templating a log-like command: .. keywordsmarker The "date" keyword does not produce human-readable output. If you want to use a date in your output, you can use a filter to process it. Filters are functions which return a string based on the input variable. Be sure to use the stringify filter first when you're applying a string-input filter to a list-like input variable. You can also use a chain of filters to get the desired output:: $ hg tip --template "{date|isodate}\n" 2008-08-21 18:22 +0000 List of filters: .. filtersmarker Note that a filter is nothing more than a function call, i.e. ``expr|filter`` is equivalent to ``filter(expr)``. In addition to filters, there are some basic built-in functions: .. functionsmarker Also, for any expression that returns a list, there is a list operator: - expr % "{template}" As seen in the above example, "{template}" is interpreted as a template. To prevent it from being interpreted, you can use an escape character "\{" or a raw string prefix, "r'...'". Some sample command line templates: - Format lists, e.g. files:: $ hg log -r 0 --template "files:\n{files % ' {file}\n'}" - Join the list of files with a ", ":: $ hg log -r 0 --template "files: {join(files, ', ')}\n" - Modify each line of a commit description:: $ hg log --template "{splitlines(desc) % '**** {line}\n'}" - Format date:: $ hg log -r 0 --template "{date(date, '%Y')}\n" - Display date in UTC:: $ hg log -r 0 --template "{localdate(date, 'UTC')|date}\n" - Output the description set to a fill-width of 30:: $ hg log -r 0 --template "{fill(desc, 30)}" - Use a conditional to test for the default branch:: $ hg log -r 0 --template "{ifeq(branch, 'default', 'on the main branch', 'on branch {branch}')}\n" - Append a newline if not empty:: $ hg tip --template "{if(author, '{author}\n')}" - Label the output for use with the color extension:: $ hg log -r 0 --template "{label('changeset.{phase}', node|short)}\n" - Invert the firstline filter, i.e. everything but the first line:: $ hg log -r 0 --template "{sub(r'^.*\n?\n?', '', desc)}\n" - Display the contents of the 'extra' field, one per line:: $ hg log -r 0 --template "{join(extras, '\n')}\n" - Mark the active bookmark with '*':: $ hg log --template "{bookmarks % '{bookmark}{ifeq(bookmark, active, '*')} '}\n" - Mark the working copy parent with '@':: $ hg log --template "{ifcontains(rev, revset('.'), '@')}\n" - Show only commit descriptions that start with "template":: $ hg log --template "{startswith('template', firstline(desc))}\n" - Print the first word of each line of a commit message:: $ hg log --template "{word(0, desc)}\n"
