Match files in root directory of repository

[njlaw]

Hello,

I have been trying to match files that are in the root directory of the repository without success. Currently, I have:

pull_request_rules:
  - name: Automatic Merge on Selected Projects
    conditions:
      - -files~=^[^/]+ # This should require that there be no files affected by the commits in the root of the repository
      - ...

However, even when no files at the root of the repository are affected in the commits of a pull request, this condition does not match.

Based on https://docs.mergify.com/conditions/#how-to-match-lists, I am assuming that there is no leading / when parsing filename in the repository.

Any insight into how this attribute is evaluated would be appreciated! I interpreted the example of files~=^(README.md|CONTRIBUTING.md)$ is true if the file README.md or CONTRIBUTING.md is modified in the pull requests. to mean that regex is supported.

I think you're a on good path. You might want to use ^[^/]+$ which means any filename that does not have / in it from start to end: that can only be a file in the root directory!

Thank you kindly! That works.

In case anyone else encounters this issue, my original regex did not work because packages from packages/app/file.ts still matches ^[^/]+. The $ is needed to ensure that files in folders fail to match.
