Removes the heaviest vendored grammar (66 MB) along with its language
wiring and test fixtures; the supported-language count moves to 158
across README, site, and manifest. The grammar manifest additionally
records the canonical-source decisions for the five
registry-disagreement grammars and the per-directory license files
restored earlier this week.
Adds Pine Script (TradingView's indicator/strategy DSL) as a first-class
language using the project's existing language-add pipeline:
- scripts/new-languages.json: register pine (display "PineScript",
ts_func tree_sitter_pine, repo kvarenzn/tree-sitter-pine, extension
.pine, has_scanner=true, module_root source_file)
- internal/cbm/vendored/grammars/pine/: vendored from
https://github.com/kvarenzn/tree-sitter-pine via scripts/vendor-grammar.sh
— parser.c, scanner.c, tree_sitter/ headers. License is ISC (declared
in upstream package.json; written into vendored LICENSE for clarity
since upstream has no LICENSE file)
- internal/cbm/grammar_pine.c: 4-line wrapper generated by
scripts/generate-lang-code.py wrappers
- internal/cbm/cbm.h: CBM_LANG_PINE before CBM_LANG_COUNT
- internal/cbm/lang_specs.c: 7 node-type arrays (func / class /
module / call / var / branch / assign) cross-checked against
kvarenzn's grammar.js, plus the spec table entry
- src/discover/language.c: .pine -> CBM_LANG_PINE extension dispatch
and "PineScript" name
scripts/audit-grammar-security.sh on the vendored grammar: no
dangerous includes (only string/stdint/stdbool/stdlib), no system /
popen / exec / socket / mmap / dlopen calls, no constructor/destructor
attributes, no inline asm. The 148-line scanner.c only handles
INDENT/DEDENT/NEWLINE tokens via the standard tree-sitter lexer API.
Distilled from #273 rather than vendored verbatim because the
original PR's parser.c was a plain 46k-line drop without provenance,
no LICENSE attribution, and bundled an unrelated Makefile change
(scripts/embed-frontend.sh -> sh scripts/embed-frontend.sh) that
didn't belong to a Pine Script feature. The node-type choices in
the lang spec match the original PR's selections, all of which were
verified to be real grammar.js rules.
Full suite: 2840 passed, 0 failed under ASan + UBSan.
Closes#273.
