Mirror of crew repo plus keyword extension: [http://www.blacktrash.org/hg/hg-crew-keyword/ Mercurial crew + keyword].

Overview

This extension allows the expansion of RCS/CVS-like and user defined keys in text files tracked by Mercurial. Expansion takes place in the working directory or/and when creating a distribution using "hg archive".

Configuration

To enable this extension add it to the '[extensions]' stanza in the hgrc file:

[extensions]
hgext.keyword=
#or, if keyword.py is not in the hgext folder:
#keyword=/path/to/keyword.py

Additional configuration is done in the [keyword] and [keywordmaps] sections in your configuration file:

# filename patterns for expansion are configured in this section
[keyword]
# expand keywords in all python files in working dir
**.py =
# do not expand keywords in files matching "x*" in working dir
x* = ignore
...
# override the cvs-like default mappings with customized keyword = expansion pairs,
# where expansion values contain Mercurial templates and filters
[keywordmaps]
HGdate = {date|rfc822date}
lastlog = {desc}
checked in by = {author}

Usage

The main functionality of the extension is done in background by automatically expanding the defined keys (or default ones), without user interaction. An additional template filter "utcdate" is provided to get %Y/%m/%d %H:%M:%S date format.

However, the extension provides the following convenience commands:

kwdemo

To get an idea what the extension actually does and/or to test your customizations (templates are rather sparsely documented), run "hg kwdemo".

Example output of "hg kwdemo --default":

        config using default keyword template maps
[keyword]
demo.txt =
[keywordmaps]
RCSFile = {file|basename},v
Author = {author|user}
Header = {root}/{file},v {node|short} {date|utcdate} {author|user}
Source = {root}/{file},v
Date = {date|utcdate}
Id = {file|basename},v {node|short} {date|utcdate} {author|user}
Revision = {node|short}

kwshrink, kwexpand

Run "hg kwshrink" before eg. changing the currently active keywords, if you don't want the expanded keywords stored in the change history.

Run "hg kwexpand" to force expansion after enabling it, or after a keyword configuration change.

Expanding keywords only in the current working copy allows you to share changes with other repos that do not have the same or no keyword setup. This can sometimes cause a problem with "hg import" if the change context contains an active keyword. To overcome this run "hg kwshrink" and (re)import. Or, better, use bundle/unbundle to share changes.
