How to hgignore all subfolders but not the file in a folder?

Question

I am looking to use nuget without committing the packages. I want to ignore in mercurial all packages subfolder that are located in the /packages/ folder, but I do not want to exclude the repositories.config file located in the /packages/ folder.

How should I write the exclusion regex to do that?

Answer 1

Can't you just do this:

hg add packages/repositories.config

And then have this in your .hgignore file

syntax: glob

packages

?

Answer 2

syntax: regexp
packages/(?!repositories.config).*
