topspeed-grammar

Corpus harness for the historical TopSpeed / JPI V3 dialect, using the sidecar grammar compiler/src/TopSpeed-V3-M2.atg.

The sidecar is a grammar deliverable: it parses the TS-V3 dialect (pragmas, H/C/B literals, ::=, anchored subranges, address constructors, CLASS/IS/VIRTUAL, manifest constants, tagless and trailing-| variant records, ...). Constructs the current backend cannot lower yet still parse and end with the standard SemError(230) marker (parse-now / lower-later), exactly like M2.atg.

Build

./build.sh        # -> build/TSM2   (build/ is git-ignored)

It copies the grammar, the V3 frames (scanner/parser/compiler.frm) and the V3 SymTab/QbeGen/FileIO sources into build/, runs CR -m -C, compiles with gm2 -fiso and links TSM2. Needs the project CR ($HOME/Projets/Projets-Modula2/MyWork/CocoGm2/CR) and GNU Modula-2.

Corpus check

./corpus.sh [corpus-dir]     # default: $HOME/bin/Dos/M2/TS-V3

Runs TSM2 over every .DEF/.MOD, copying each into a scratch tree so the .LST listings never touch the corpus, and reports:

  • parse-OK — only the deliberate 230/semantic markers,
  • syntax-bad — a real Coco/R error ('x' expected, invalid X).

Current result on the TS-V3 tree (662 files, 352 .DEF + 310 .MOD): 631 parse-OK / 31 syntax-bad — see docs/summary_topspeed-corpus.md.
