nx_glsl_tokdiff.nx

nx_glsl_tokdiff.nx -- THE SHADER TOKEN RULER, the program (gameengine S12c accept-rule instrument, 2026-09-05). usage: nx_glsl_tokdiff <a.glsl> <b.glsl> -> THE CANONICAL DIFF (S12c-2): whitespace, comments, numeric spelling, compound assignment, redundant parentheses, multi-declarators, brace-less branches and counted loops normalised (see nx_glsl_tok_lib, THE CANONICAL FORM); exit 0 IDENTICAL / 1 DIFFERS / 2 UNREADABLE (the refusing token is named by byte offset and spelling). shorter_is_prefix=1 is the per-SLICE accept signal of the cast port: an emitted slice is proven when its canonical stream is a prefix of the hand text's, the whole shader when the verdict reads IDENTICAL. nx_glsl_tokdiff raw <a.glsl> <b.glsl> -> the incumbent token-level ruler (no structural normalisation), kept runnable so the canonical form can always be measured against what it replaced. nx_glsl_tokdiff extract <src> <start-marker> <end-marker> <out> [endincl] -> copies the text between the markers (start exclusive; end exclusive, or INCLUSIVE with the endincl word) and UNESCAPES the JS-literal spellings \n \" \\ so a shader embedded in a page emitter's string can be judged as shader text. A backtick right after the start marker (a JS template-literal opener) is skipped, so no caller has to pass a backtick through a launcher (measured 2026-09-05: the argument vanished and the run printed nothing). exit 0 / 2 One ruler (nx_glsl_tok_lib), composed in-process; the gate drives the same lib over planted fixtures in both directions. license_tier: ORIGINAL No hw writes (Rule 26).
