#Packages

#Compatibility

• The upstream test suite is ported test by test; around 1,500 tests run on native, js and wasm-gc, including thousands of differential cases generated with Python Rich (scripts/*_oracle.py), the full feature card at width 100, all 652 CommonMark spec examples for Markdown and 36 languages × 13 themes for Syntax.
• MoonBit has no threads and no runtime introspection: Live/Progress refresh on updates (or tick()), or from a timer with @aio in async code; pretty works through the PrettyRepr trait; tracebacks are rendered from data you provide; inspect and Jupyter support are not ported.

#Performance

moon run --target native --release cmd/bench            # or: -- table syntax
moon build --target wasm-gc --release cmd/bench
moonrun _build/wasm-gc/release/build/cmd/bench/bench.wasm
