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".

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: "hg import" fails 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
