How do I specify a case insensitive ignore?

Asked by authorunknown

Is there any way to specify a case insensitive glob in an ignore pattern, or direct the pattern matcher to construct a regex using the re.IGNORECASE flag?

This would be helpful, especially on case insensitive file systems. for example, right now my ignore files are littered with lines like:

/**/[Bb][Ii][Nn]/

this ignores all casings of a directory named bin, but it becomes cumbersome and ugly when the paths start getting longer

You can use the regular expression syntax for ignore. Python allows having flags as part of the expression with extension notation[1]. For e.g. for case insensitive match for the name "foo" you could do:

bzr ignore "RE:(?i)foo"

[1] http://docs.python.org/library/re.html - look for "(?" on the page.

Thank you. I'm not very familiar with Python and couldn't find that bit of information about including the flags in the pattern string -- exactly what i needed.
