tur (C++ ports)

This workspace contains C++ ports of parse.ts and run.ts.

Files:

• parse.cpp - parser that reads a .rec source file and produces a simple AST JSON.
• run.cpp - runtime that reads the AST JSON and executes a subset of commands.

Usage (build and run):

g++ -std=c++17 parse.cpp -o parse
g++ -std=c++17 run.cpp -o run

./parse [-d|--dump] [-l|--loud] <source-file>
# when -d is passed, parser writes <source-file>-ast.json

./run <ast-file.json>

Notes:

• The parser is a minimal port and enforces some argument rules; some existing .rec files in the repo may fail to parse if they use commands the parser expects different argument counts for.
• The runtime implements a subset of functions from the original run.ts (arithmetic, print, set/get, goto/if/return/read). It uses a small JSON reader tailored to the parser output.
• If you prefer robust JSON parsing in C++, we can switch to nlohmann/json (requires adding the single-header include or package).

Next steps you might want:

• Extend the runtime to support more commands ($randInt, $catFact, etc.)
• Improve parser error messages and permissiveness to match the TypeScript version exactly.
