hgignore multi line regex

I googl开发者_运维知识库ed a bit, but didn't find any suggestions on that topic. Is multi line regex possible in .hgignore? I'm writing a magento module, and wan't to include only my module code in repository, so I came up with this regex, but it would a be mess, if I had to write it in one line.

syntax: regexp
^(?!(
   app/code/local/Mage/Myreviews/|
   app/design/frontend/default/default/layout/myreviews\.xml|
   app/design/frontend/default/default/template/myreviews/|
   app/etc/modules/Mage_Myreviews\.xml|
   skin/frontend/default/default/css/myreviews/|
   skin/frontend/default/default/myreviews/|
   js/myreviews/
)).*

As for the canonical answer to your question, are multi-line regular expressions supported? No. For confirmation, take a look at the ignorepats function in ignore.py in the mercurial Python package—it iterates over the lines in the file one by one.

As for what you should do instead, @jk.'s answer is good (and the glob: * that you've come up with).

You can add files to a repository and have mercurial track them even if they match an ignore rule, so usually the best way to do this sort of thing is to ignore a bit too much e.g. (don't know anything about magneto modules so this may be wrong)

syntax: glob
app/*
skin/*
js/myreviews/*

and then explicitly hg add the files you do want.

As Joel points out hg adds --include and --exclude options are also useful in these scenarios

pre-emptive additional info: hg forget will undo tracking a file without deleting it
