expansion

Overview ¶

Package expansion applies shell-style expansion to command argument tokens: tilde expansion then pathname globbing, on unquoted tokens only.

A glob with no matches is left literal (POSIX default, no "nullglob"), so non-matching patterns reach the command unchanged. Expansion resolves globs against an injected afero.Fs, so it stays testable against an in-memory tree; it holds no knowledge of the REPL or of command semantics.
