Replace the last three intubun/tcl mentions with tcltk/tcl in
npm/tcl.js, toolchains/emscripten/build-tcl-wasm.sh, and npm/tcl.ref.
Also remove the stale comment in tcl.ref that referenced a non-existent
update-tcl GitHub Actions workflow.
Bump VERSION to 8.3.645.
magic.wasm can now be built as two variants packaged in the same npm
release: notcl/ (legacy, magic's own parser) and tcl/ (intubun/tcl 9.x
statically linked, commands evaluated by Tcl_EvalEx). The TCL fork is
pinned via npm/tcl.ref and cloned/built by magic itself — the tcl/
checkout is treated as read-only and built out-of-source into
magic/build-tcl-wasm/.
Configure layer:
- New usingTk variable decoupled from usingTcl in scripts/configure.in
+ scripts/configure, so --with-tcl --without-tk is finally a valid
combination. Native Linux Tcl+Tk builds keep their previous behaviour
(both flags default to enabled).
- When usingTk is empty, configure passes -DMAGIC_NO_TK so the small
number of remaining Tk callsites in tcltk/tclmagic.{h,c} compile out,
and TKCOMMON_SRCS / USE_TK_STUBS are omitted from the link.
WASM build orchestration:
- toolchains/emscripten/build-tcl-wasm.sh builds libtcl9.x.a + libtclstub.a
+ tclConfig.sh out-of-source from a pristine intubun/tcl checkout.
- npm/build.sh grew a --variant=<tcl|notcl|both> flag and writes its
outputs into npm/tcl/ and npm/notcl/. It also clones intubun/tcl with
autocrlf=false at the SHA pinned by npm/tcl.ref.
- magic/Makefile (WASM block only): magicWasm.o is now compiled with
DFLAGS_NOSTUB so Tcl_CreateInterp resolves to libtcl9.x directly
before tclStubsPtr is set. magic.js link pulls in LIB_SPECS_NOSTUB
and -ltclstub. After rules.mak include, magic: is a phony alias for
magic.js so the generic ${MODULE} recipe doesn't fight it.
- toolchains/emscripten/defs.mak: add -sUSE_ZLIB=1 (libtcl9 references
zlib), replace -sSTACK_SIZE=N with -Wl,-z,stack-size=N (emcc >=5
rejects the setting form).
- magic/magicWasm.c bootstraps the embedded interp under MAGIC_WRAPPER
(Tcl_CreateInterp -> Tcl_Init -> Tclmagic_Init) and routes
run_command through Tcl_EvalEx.
- magic/magicTop.c: gate MagicVersion/Revision/CompileTime on
!MAGIC_WRAPPER so they don't collide with the copies in
tcltk/tclmagic.c when both objects land in the same wasm binary.
npm package:
- Subpath exports: ".", "./tcl", "./notcl". Default import keeps the
pre-existing non-TCL behaviour for backward compatibility.
- examples/smoke-tcl.mjs exercises the TCL variant.
CI:
- main-wasm.yml clones intubun/tcl at the pinned ref, builds both
variants via npm/build.sh --variant=both, runs the existing notcl
test suite and the new TCL smoke test, and publishes only on a
v<x.y.z>... git tag. Tag name (minus the leading v) becomes the
npm version.
