I'm using Mercurial and I have a following structure: <pre class="prettyprint"><code>files test demo.jpg video.flv video.doc sport demo2.jpg picture.jpg text.txt demo3.jpg demofile3.doc </code></pre> 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.

If you are happy to ignore "all JPG files inside any directory named <code>files</code>", then use <pre class="prettyprint"><code>syntax: glob files/**.jpg </code></pre> See <code>hg help patterns</code> which explains that <code>**</code> is a glob operator that spans directory separators. This means that the file <pre class="prettyprint"><code> files/test/demo.jpg </code></pre> is matched by <code>files/**.jpg</code>. However, note that glob patterns are not rooted. This means that a file named <pre class="prettyprint"><code> test/files/demo.jpg </code></pre> will also be ignored since it matches the pattern after you remove the <code>test/</code> prefix. You need to use a regular expression if you are concerned with this. In that syntax, the pattern reads <pre class="prettyprint"><code>syntax: regex ^files/.*\.jpg </code></pre> 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.

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.

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.

Regexp solution

This works for me ..

syntax: regexp
files/.*/.*jpg

Your own solution looks more like a glob. The trick with that is to use the ** syntax to allow for sub directories. See this ...

Glob solution

This glob works for me too

**/files/**/*.jpg
