neco-pathrel

日本語

String-based path relation helpers for checking subtree membership and rewriting paths through file or directory renames.

Path handling

neco-pathrel compares path strings under an explicit PathPolicy instead of consulting the filesystem. Callers choose the separator and case-sensitivity once, then reuse the same policy for subtree checks, parent lookup, path joining, and rename remapping.

The crate does not canonicalize ., .., symlinks, drive letters, or UNC paths. It stays at the level of runtime path strings so behavior stays deterministic across hosts.

Usage

use neco_pathrel::{path_matches_or_contains, remap_path_for_rename, PathPolicy};

let policy = PathPolicy::posix();

assert!(path_matches_or_contains(
    "/workspace/src/lib.rs",
    "/workspace/src",
    &policy,
));

let renamed = remap_path_for_rename(
    "/workspace/src/lib.rs",
    "/workspace/src",
    "/workspace/core",
    &policy,
);
assert_eq!(renamed.as_deref(), Some("/workspace/core/lib.rs"));

API

Item	Description
`PathPolicy::new(separator, case_sensitivity)`	Construct an explicit path comparison policy
`PathPolicy::posix()`	Construct the default POSIX-like policy
`path_matches_or_contains(path, target, policy)`	Return whether `path` equals `target` or lies under `target`
`parent_path(path, policy)`	Return the direct parent slice when one exists
`join_path(base, name, policy)`	Join two path fragments with one separator
`remap_path_for_rename(path, source, target, policy)`	Rewrite one path through a file or subtree rename
