Module fs 

Small filesystem-path helpers shared across the workspace.

Functions

expand_tilde

Expand a leading ~ or ~/ in path against home. A path that does not begin with a tilde segment is returned unchanged.

expand_tilde_env

Expand a leading ~/~/ in path against $HOME, read from the process environment. A path without a tilde segment — or when $HOME is unset — passes through unchanged.

find_on_path

Find binary on the process PATH, returning the first executable match.

is_executable

Whether path is an existing regular file the process may execute (on non-Unix, merely an existing file — there is no mode bit to check).
