Given a project directory my-project which projectile correctly identifies because it is a git project.
Inside my-project there is a my-module directory. It is a git submodule and therefor projectile identifies it as a project of it's own.
But I want all files inside of my-project/my-module to be considered as part of my-project.
What is the idiomatic way to configure this?
I would like a solution in dir-locals.el so it does not affect other projects.
The solution was putting this into my-project/my-module/.dir-locals.el:
((nil . ((projectile-project-root . "/p/my-project/")))) See the issues: https://github.com/bbatsov/projectile/issues/712 / https://github.com/bbatsov/projectile/issues/1449.
One of the options suggested there is to (edit: I've changed projectile-project-root-files-functions -> projectile-project-root-functions which it was aliased to):
(setq projectile-project-root-functions '(projectile-root-local projectile-root-top-down projectile-root-top-down-recurring projectile-root-bottom-up)) Edit: I see you want this to not to affect other projects so you'd want to put this in .dir-locals.el in the project root.
projectile-project-info identifies the sub project as the project. .projectile or .dir-locals vars which could be setting the project root? If you'd be open to sharing the project link, I could clone and see if I can reproduce what you're seeing. .dir-locals.el file you mention you have from the submodule root to the project root should also work.
counsel-fdif your goal is to just browse subdirectories and files withinmy-project.
