keyword extension - keyword expansion in local repositories

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 repos.

For [keywordmaps] template mapping and expansion demonstration and

control run "hg kwdemo".

An additional date template filter {date|utcdate} is provided.

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 inadvertedly 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.

Caveat: With Mercurial versions prior to 4574925db5c0 "hg import" might

        cause rejects if the patch context contains an active keyword.

        In that case run "hg kwshrink", and then reimport.

        Or, better, use bundle/unbundle to share changes.

 kwdemo     print [keywordmaps] configuration and an expansion example

 kwexpand   expand keywords in working directory

 kwfiles    print files currently configured for keyword expansion

 kwshrink   revert expanded keywords in working directory

% hg kwdemo
