Module paths 

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

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

Test a path against the loaded .yuiignore matcher.

load_yuiignore

Load $source/.yuiignore as a gitignore-style matcher.

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 yui’s internal .yui/ directory.
