Function is_ignored

crates/openshell-bootstrap/src/build.rs:370–385

Check whether a relative path should be ignored based on `.dockerignore` patterns. Uses a simple glob-matching approach: patterns are matched against the full relative path. A leading `/` anchors to the context root. The last matching pattern wins (negation patterns re-include files).

(relative_path: &str, is_dir: bool, patterns: &[IgnorePattern])

/// full relative path. A leading `/` anchors to the context root. The last
/// matching pattern wins (negation patterns re-include files).
fn is_ignored(relative_path: &str, is_dir: bool, patterns: &[IgnorePattern]) -> bool {
    let mut ignored = false;

    for pat in patterns {
        let pattern = pat.pattern.trim_start_matches('/');

        // Check if the pattern matches.
        let matches = glob_match(pattern, relative_path, is_dir);

        if matches {
            ignored = !pat.negated;
        }
    }

    ignored
