- @as builtin: propagate RL_TY with dest_type through exprRl instead of evaluating operand with RL_NONE and manually emitting as_node. Matches upstream AstGen.zig lines 8909-8920. - rlResultType: add missing RL_REF_COERCED_TY case (elem_type extraction). - continue handler: use AST_NODE_OFFSET_NONE for addBreak operand_src_node instead of computing node offset. Upstream uses addBreak (not addBreakWithSrcNode), which writes .none. - varDecl: set init_rl.src_node = 0 for RL_PTR (upstream leaves PtrResultLoc.src_node at default .none). Enables astgen_test.zig corpus test — all corpus tests now pass. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
About
zig0 aspires to be an interpreter of zig 0.15.1 written in C.
This is written with help from LLM:
- Lexer:
- Datastructures 100% human.
- Helper functions 100% human.
- Lexing functions 50/50 human/bot.
- Parser:
- Datastructures 100% human.
- Helper functions 50/50.
- Parser functions 5/95 human/bot.
- AstGen: TBD.
Testing
Quick test:
zig build fmt test
Full test and static analysis with all supported compilers and valgrind (run before commit, takes a while):
zig build -Dvalgrind
Debugging tips
Test runs infinitely? Build the test program executable:
$ zig build test -Dno-exec
And then run it, capturing the stack trace:
gdb -batch \
-ex "python import threading; threading.Timer(1.0, lambda: gdb.post_event(lambda: gdb.execute('interrupt'))).start()" \
-ex run \
-ex "bt full" \
-ex quit \
zig-out/bin/test
You are welcome to replace -ex "bt full" with anything other of interest.
