Use .ignore file file content to ignore files.

[thomaswitt]

Description

By default, repomix should use the .ignore file as well. This seems to have evolved as the standard used by ripgrep, the silver searcher and others. Usually files you don't want to search in should be also excluded in the repomix. Benefit is not having to maintain multiple ignore files.

A summary of the changes CodeRabbit can apply:

• Add default .ignore support to repomix by updating src/core/file/fileSearch.ts to include '**/.ignore' in getIgnoreFilePatterns, updating tests/tests/core/file/fileSearch.test.ts to expect .ignore in returned patterns, and revising README.md to document .ignore support and the new priority order (placed at priority 3).

• Add support and documentation for honoring a project-level .ignore file by updating README.md to mention .ignore alongside .gitignore and .repomixignore, modifying src/core/file/fileSearch.ts to always include '/.ignore' in ignore-file discovery, and updating tests/tests/core/file/fileSearch.test.ts expectations to include '/.ignore'.

Hi, @thomaswitt !
Thanks for the suggestion!

I wasn't familiar with .ignore before. Since rg and fd support it, it makes sense to add support.

I'll consider whether to enable it by default or make it opt-in.

I'm planning to enable .ignore by default. Technically it's a breaking change, but I believe most users who create .ignore files would expect this behavior.

The nature of .ignore is "things you want in git but exclude from rg/fd searches", meaning they're likely less important for other tasks too, and probably unnecessary for AI as well.

Hi @yamadashy,

first thanks for your effort and your quick response. I just gave it a quick spin, and it didnt appear to do what I expected it to do.

I have a file .ignore file which should ignore everything in spec/data/:

❯ ls -a .ignore
.ignore
❯ grep 6261426af2228b5341bea653 spec/data/openaip/de_apt.json | cut -c1-35
[{"_id":"6261426af2228b5341bea653",
❯ rg 6261426af2228b5341bea653
❯ echo $?
1
❯ ag 6261426af2228b5341bea653
❯ echo $?
1

Works fine with ripgrep. But when I try it with repomix, spec/data/ gets included:

❯ repomix -v
1.9.0
❯ repomix | grep de_apt
1.  spec/data/openaip/de_apt.json (609,870 tokens, 1,810,548 chars, 34.4%)
❯ grep 6261426af2228b5341bea653 ~/Downloads/repomix-output.md | cut -c1-35
