 # keyword.py - $Keyword$ expansion for Mercurial

 # Keyword expansion hack against the grain of a DSCM
 #
 # There are many good reasons why this is not needed in a distributed
 # SCM, still it may be useful in very small projects based on single
 # files (like LaTeX packages), that are mostly addressed to an
 # audience not running a version control system.
 #
 # For in-depth discussion refer to
 # <http://mercurial.selenic.com/wiki/KeywordPlan>.
 #
 # Keyword expansion is based on Mercurial's changeset template mappings.
 #
 # Binary files are not touched.
 #
 # Files to act upon/ignore are specified in the [keyword] section.
 # Customized keyword template mappings in the [keywordmaps] section.
 #
 # Run "hg help keyword" and "hg kwdemo" to get info on configuration.
 
 '''expand keywords in tracked files
 
 This extension expands RCS/CVS-like or self-customized $Keywords$ in
 tracked text files selected by your configuration.
 
 Keywords are only expanded in local repositories and not stored in the
 change history. The mechanism can be regarded as a convenience for the
 current user or for archive distribution.
 
 Configuration is done in the [keyword] and [keywordmaps] sections of
 hgrc files.
 
 Example::
 
     [keyword]
     # expand keywords in every python file except those matching "x*"
     **.py =
     x*    = ignore
 
 NOTE: the more specific you are in your filename patterns the less you
 lose speed in huge repositories.
 
 For [keywordmaps] template mapping and expansion demonstration and
 control run "hg kwdemo". See "hg help templates" for a list of
 available templates and filters.
 
 An additional date template filter {date|utcdate} is provided. It
 returns a date like "2006/09/18 15:13:13".
 
 The default template mappings (view with "hg kwdemo -d") can be
 replaced with customized keywords and templates. Again, run "hg
 kwdemo" to control the results of your config changes.
 
 Before changing/disabling active keywords, run "hg kwshrink" to avoid
 the risk of inadvertently storing expanded keywords in the change
 history.
 
 To force expansion after enabling it, or a configuration change, run
 "hg kwexpand".
 
 Also, when committing with the record extension or using mq's qrecord,
 be aware that keywords cannot be updated. Again, run "hg kwexpand" on
 the files in question to update keyword expansions after all changes
 have been checked in.
 
 Expansions spanning more than one line and incremental expansions,
 like CVS' $Log$, are not supported. A keyword template map "Log =
 {desc}" expands to the first line of the changeset description.
