.hgignore whole directory tree excepting one specific file

问题

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.

回答1:

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.

回答2:

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

almost the same as John Mee's but matches to the end of the line, instead of anything that starts with default.png.

if you wanted to allow any .c file but nothing else, you could use:

^media/(?!.+\.c$)

Summing it up as a BKM (Best Known Method)

Either hgignore everything, and then hg add back the few files you want to track.

Or use a pattern such as

syntax: regex
^path/(?!files-that-you-want-not-to-ignore$)

(I just wanted to see the full answer in one place.)

Never mind this seems to work...

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