test: run kwdemo before setting up [keyword] files
kwdemo would pass the test without uisetup otherwise.
Also no need to specify --default option.
# keyword.py - $Keyword$ expansion for Mercurial## Copyright 2007-2009 Christian Ebert <blacktrash@gmx.net>## This software may be used and distributed according to the terms of the# GNU General Public License version 2, incorporated herein by reference.## $Id$## 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://www.selenic.com/mercurial/wiki/index.cgi/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 filesThis extension expands RCS/CVS-like or self-customized $Keywords$ intracked text files selected by your configuration.Keywords are only expanded in local repositories and not stored in thechange history. The mechanism can be regarded as a convenience for thecurrent user or for archive distribution.Configuration is done in the [keyword] and [keywordmaps] sections ofhgrc files.Example:: [keyword] # expand keywords in every python file except those matching "x*" **.py = x* = ignoreNOTE: the more specific you are in your filename patterns the less youlose speed in huge repositories.For [keywordmaps] template mapping and expansion demonstration andcontrol run "hg kwdemo". See "hg help templates" for a list ofavailable templates and filters.An additional date template filter {date|utcdate} is provided. Itreturns a date like "2006/09/18 15:13:13".The default template mappings (view with "hg kwdemo -d") can bereplaced with customized keywords and templates. Again, run "hgkwdemo" to control the results of your config changes.Before changing/disabling active keywords, run "hg kwshrink" to avoidthe risk of inadvertently storing expanded keywords in the changehistory.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" onthe files in question to update keyword expansions after all changeshave 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.'''frommercurialimportcommands,cmdutil,dispatch,filelog,revlog,extensionsfrommercurialimportpatch,localrepo,templater,templatefilters,util,matchfrommercurial.hgwebimportwebcommandsfrommercurial.lockimportreleasefrommercurial.nodeimportnullidfrommercurial.i18nimport_importre,shutil,tempfilecommands.optionalrepo+=' kwdemo'# hg commands that do not act on keywordsnokwcommands=('add addremove annotate bundle copy export grep incoming init'' log outgoing push rename rollback tip verify'' convert email glog')# hg commands that trigger expansion only when writing to working dir,# not when reading filelog, and unexpand when reading from working dirrestricted='merge record resolve qfold qimport qnew qpush qrefresh qrecord'# provide cvs-like UTC date filterutcdate=lambdax:util.datestr(x,'%Y/%m/%d %H:%M:%S')# make keyword tools accessiblekwtools={'templater':None,'hgcmd':'','inc':[],'exc':['.hg*']}classkwtemplater(object):''' Sets up keyword templates, corresponding keyword regex, and provides keyword substitution functions.
