A Walking Tour of Wasm-Tools
summary
Command-line wasm-tools proves a working toolkit: print/validate/demangle/strip/objdump parse and json-from-w convert and inspect binaries and text, smith deterministically generates fuzzed modules and can allow-invalid-funcs, mutate tweaks them and shrink reduces a failing 3.5KB test down to 136 bytes to isolate a Wasmtime panic, and strip removes debug sections turning a 1.7MB hello.wasm into 54 kilobytes. Dwarf-backed validation maps binary offsets to text lines, component wit/embed/new roundtrips component types, and wasm-tools itself compiles to wasm and runs under Wasmtime.
