debugger

name	debugger
description	Use rust-gdb to inspect variables and step through code without modifying it. Prefer this over print debugging when investigating compiler internals or runtime behavior (lldb is unavailable on Claude Code Web).

Debugger

Debug wado compiler with rust-gdb.

Usage

cat > /tmp/gdb_commands.txt << 'EOF'
file ./target/debug/wado
set pagination off
break wado-compiler/src/codegen.rs:5985
run compile -o /tmp/out.wasm example/hello.wado
info locals
print *expr
bt 5
quit
EOF
rust-gdb --batch -x /tmp/gdb_commands.txt

Common commands

Command	Description
info locals	Show local variables
print *expr	Dereference and print pointer
bt 5	Backtrace (top 5 frames)
continue	Resume execution

Notes

lldb does not work in Claude Code Web due to ptrace restrictions:

error: Cannot launch '...': personality get failed: Invalid argument

Use rust-gdb instead.
