keyword extension - 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".

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 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.

list of commands:

 kwdemo     print [keywordmaps] configuration and an expansion example

 kwexpand   expand keywords in the working directory

 kwfiles    show files configured for keyword expansion

 kwshrink   revert expanded keywords in the working directory

enabled extensions:

 keyword   expand keywords in tracked files

 mq        manage a stack of patches

 notify    hooks for sending email notifications at commit/push time

use "hg -v help keyword" to show aliases and global options
