Neat, thanks for working on this! I think the usual term is "parent folder". I hope this will be merged!

[ggreer]

It segfaults in the tests so... probably not going to get merged.

[forgottenswitch]

Rebased and updated for 1.0.1

[Vijar]

+1 to this!

@ggreer can we get this merged please?

@ggreer I landed here looking for a solution to this issue.

I checked out and compiled the latest version from @forgottenswitch, and it seems to work as advertised. It makes my life easier when wandering around the codebase I'm currently spending the most time in at $DAYJOB.

Per the CI results above, the rebased version shows no sign of the segfault you mention from the original submission. make test says:

# Ran 39 tests, 1 skipped, 0 failed.
clang-format is not available. Skipped clang-format test.

I can offer a basic test for this functionality, which this PR doesn't seem to have yet.

Would you reconsider merging this?

The previous version (backed up at https://github.com/ggreer/the_silver_searcher/compare/master...forgottenswitch:gitignore_win32) had two issues:

• Did not handle sub-repositories
• Tried to handle Win32 paths
• Also had a base_path -> path typo in search_dir :)

Now this partially implements #284 the other way (read ignores into another list instead of restricting the current one).

[forgottenswitch]

Factored tests and function names for readability. Squashed commits to avoid the flood. Added more tests. Stopped attempting a malloc-less dirname, – just using copies now.
