Ignore files in Mercurial using Glob syntax

Question

I'm using Mercurial and I have a following structure:

files
   test
       demo.jpg
       video.flv
       video.doc

   sport
       demo2.jpg
       picture.jpg
       text.txt
demo3.jpg
demofile3.doc

I want to make a glob filter that only ignore all "jpg" files in all directory that are children of "files" directory

I tried with files/*.jpg but it doesn't work.

Any advice would be appreciated.

Answer 1

Does it have to be glob syntax? If you use regex syntax, files/.*\.jpg should work.

Answer 2

Chris McCauley thank you. globstars amazing! But isnt working with mercurial! Any ideas?

from .hgignore

syntax: glob
LaTeX/**/*.pdf

(how do I comment instead of answer?)

Answer 3

If you are happy to ignore "all JPG files inside any directory named files", then use

syntax: glob
files/**.jpg

See hg help patterns which explains that ** is a glob operator that spans directory separators. This means that the file

 files/test/demo.jpg

is matched by files/**.jpg.

However, note that glob patterns are not rooted. This means that a file named

 test/files/demo.jpg

will also be ignored since it matches the pattern after you remove the test/ prefix.

You need to use a regular expression if you are concerned with this. In that syntax, the pattern reads

syntax: regex
^files/.*\.jpg

I would normally not worry about rooting the pattern -- I prefer the simplicity of the glob patterns. But it's nice to know that you can root a ignore pattern if you really have to.
