Module paths 

Path utilities for backup-mirroring, timestamp suffixing, and cross-platform tilde expansion.

Structs

YuiIgnoreStack

Stack of .yuiignore matchers for manual recursive walks. Each frame remembers the directory it was loaded from + the parsed matcher; testing a path walks innermost → outermost so a deeper .yuiignore overrides a shallower one (gitignore semantics).

Functions

append_timestamp

Append a timestamp before the extension.

expand_tilde

Expand a leading ~ or ~/... to the user’s home directory.

expand_tilde_with

Same as expand_tilde but with an explicit home path — used in tests to avoid touching the process-wide HOME env var.

home_dir

$HOME (Unix) or $USERPROFILE (Windows), or None if neither is set.

is_ignored_at

One-shot .yuiignore test for a single path under source.

mirror_into_backup

Mirror an absolute target path into a backup directory, dropping the drive colon on Windows so the path is filesystem-safe.

source_walker

Build a source-tree walker that skips repo plumbing.
