Question

I have a large file system in which almost every folder has a file called content.txt

I want to track every file named content.txt and automatically ignore everything else. I want the repo to automatically track new files named content.txt so I don’t want to ignore everything in the .hgignore and then manually add.

Anyone know how to do this?

Answer 1

1. It has to be regexp mode, not glob
2. You must debug path-part of regexp, but “all except content.txt” draft is re:.*\.(?!content.txt) as hope

Alternative solution can be
* ignore all
* add content.txt files pattern to commit command (-I option), see hg help commit and hg help patterns

hg commit -I '**content.txt'

Edit

re:.*/(?!content.txt)
