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
