about

nx_path.nx -- POSIX path utilities (basename, dirname, join, normalize, ext). The toolchain front-ends (nx_toolchain, nxc_native_wrap, nxld, nxasm) all need to manipulate paths: derive output filenames from input filenames (foo.nx -> foo.s -> foo.o -> foo.elf), strip directory prefixes for log lines, build search paths. Today each tool inlines its own ad-hoc string scanning. This module centralises the operations under a clean API. Conventions match POSIX (forward slashes, "." and ".." segments). Windows backslash paths are out of scope -- nxc2 normalises them at the input layer.
