.hgignore whole directory tree excepting one specific file

Question

Can anyone tell me the .hgignore pattern to track one specific file in a directory and to ignore everything else?

I have a "media" directory which contains a "default.png", for obvious purposes, and the rest of the directory will hold user media. We want hg to ignore everything in the media directory excepting the default file.

Answer 1

Never mind this seems to work...

syntax: regex
^media/(?!default.png)

Answer 2

Try:

syntax: regex
^media/.*

or (leave it in the default glob and do)

media/**

and then manually hg add media/default.png.

In mercurial (unlike in CVS) you can add files that match your ignore patterns and they work fine. So ignore broadly and hg add what you want tracked.
