Function module_gen_key 

pub fn module_gen_key(path: &Path, lint: Option<&str>) -> Key

The key for a module’s checked-and-generated form, by the file it is.

A test file is keyed by its spelling (gen_key) because the runner prints that spelling. A module reached through require is another matter: the test runner meets it by the path the checker resolved, the linker by the one it resolved, htl build and include_bundle! from different working directories — and its generated Lua is the same file’s Lua whichever way it was reached. So the key is the canonical path and the lint selection, and nothing about the invocation, and the entry is stamped without the binary (the entry’s stamp): that is what lets htl test, htl build and the macros replay one another’s entries (#100).
