Overview

Consistent .gitignore-aware file filtering shared by the grep Ruby fallback and the glob tool (#375b/#375c).

The PROBLEM: grep’s ripgrep path honors .gitignore, but the Ruby fallback (‘Dir.glob(“*/”)`) did not — so `grep` returned a DIFFERENT, larger set (including build artifacts, node_modules, secrets in ignored files) depending on whether rg happened to be installed. Non-deterministic, and a leak of ignored content. The glob tool ignored .gitignore entirely too.

The FIX: a single ignore oracle both non-rg paths consult, matching rg’s default semantics as closely as a non-rg implementation can:

* In a git repo, the canonical answer is `git ls-files --cached --others
  --exclude-standard` (tracked + untracked-but-not-ignored) — EXACTLY
  the set rg searches by default. We build the allowed-path set from it.
* Outside a repo (or if git fails), fall back to a small built-in
  denylist of always-noise dirs (.git, node_modules, …) so behaviour is
  still deterministic and never leaks the VCS internals.

Per-root results are cached for the life of the instance, so a single grep/glob call pays the git cost once.

Instance Method Details

#ignored?(abs_path, root) ⇒ Boolean

True when abs_path (an absolute file path) should be EXCLUDED from results given root (the search base). Consistent across grep-fallback and glob: a path git ignores (or the fallback denylist matches) is ignored regardless of whether rg is installed.

Returns:

  • (Boolean)
