FastParse COBOL Language Extension

Status: Stable

This extension registers the canonical FastParse parse language:

cobol

It uses the vendored grammar at grammars/tree-sitter-cobol and exports:

fastparse_language_extension_descriptor
tree_sitter_COBOL

Build locally from the vendored grammar:

cmake -S . -B build-cobol-extension -DCMAKE_BUILD_TYPE=Release \
  -DFASTPARSE_COBOL_GRAMMAR_DIR=grammars/tree-sitter-cobol
cmake --build build-cobol-extension --config Release --target fastparse_language_cobol

Package a local native archive:

python3 scripts/package_language_extension.py \
  --language cobol \
  --version 0.1.1 \
  --platform macos \
  --arch arm64

Load explicitly:

from fastparse import FastParse

parser = FastParse()
parser.load_language_extension("bin/libfastparse_language_cobol.dylib")
result = parser.parse_text(cobol_source, language="cobol")

The grammar accepts full COBOL programs, copybook fragments, and COBOL sources with embedded EXEC SQL ... END-EXEC blocks. Fixed-column and legacy layout normalization is handled before parsing by FastParse or the lab validation tools.

For NuGet publication, publish the core FastParser package and FastParser.Language.Cobol as a matched pair. Raw enterprise COBOL can include CP037/EBCDIC files, tab-indented copybooks, fixed-column sources shifted toward column 1, missing statement terminators before area-A paragraph headers, and continuation marker variants; those cases require a core version whose auto_safe / cobol_fixed_legacy normalization prepares a conservative in-memory parser view.
