💅 WABT(1) — wasm-stats, bestie edition 🎀

okay so real quick, this whole page lives in the General Commands Manual for WABT, and today's main character is wasm-stats. she's the one we're talking about. let's go ✨

🌸 NAME 🌸

wasm-stats — show stats for a module. that's it, that's the job. she counts things so you don't have to 🫶

🦋 SYNOPSIS 🦋

wasm-stats [options] filename+

notice the filename+?? that plus is doing SO much work. you can hand her more than one file, bestie. she'll take them all, no cap 💖

✨ DESCRIPTION ✨

wasm-stats reads a file in the wasm binary format and outputs stats. like, she looks at your module and goes "here's the tea, here's the numbers" 📊🔥

The options are as follows:

  • --help — print this help message. the classic. the icon.
  • --version — print version information. identity check 🪞
  • -v, --verbose — use multiple times for more info. yes, you can stack her. more -v = more yapping, and honestly we love that for us 💬
  • --disable-exceptions — disable experimental exception handling
  • --disable-mutable-globals — disable import/export mutable globals
  • --disable-saturating-float-to-int — disable saturating float-to-int operators
  • --disable-sign-extension — disable sign-extension operators
  • --disable-simd — disable SIMD support
  • --enable-threads — enable threading support 🧵
  • --enable-function-references — enable typed function references
  • --disable-multi-value — disable multi-value
  • --disable-tail-call — disable tail-call support
  • --disable-bulk-memory — disable bulk-memory operations
  • --disable-reference-types — disable reference types (externref)
  • --disable-annotations — disable custom annotation syntax
  • --enable-code-metadata — enable code metadata
  • --enable-gc — enable garbage collection 🗑️✨
  • --disable-memory64 — disable 64-bit memory
  • --disable-multi-memory — disable multi-memory
  • --disable-extended-const — disable extended constant expressions
  • --disable-relaxed-simd — disable relaxed SIMD
  • --enable-custom-page-sizes — enable custom page sizes
  • --enable-compact-imports — enable compact import section
  • --enable-wide-arithmetic — enable wide arithmetic
  • --enable-all — enable all features. the "just give me everything" option, the girl dinner of flags 🍽️👑
  • -o, --output=FILENAME — output file for the stats, by default use stdout
  • -c, --cutoff=N — cutoff for reporting counts less than N. i.e. if a count is below N, she's not reporting it. keep it cute, keep it filtered 💅
tiny note bestie: the disable ones start enabled-ish and the enable ones start off — that's literally what "enable"/"disable" means here, i'm not out here inventing lore 🙈

🌈 EXAMPLES 🌈

parse binary file test.wasm and write opcode dist file test.dist:

$ wasm-stats test.wasm -o test.dist

see how easy that was?? one line, one dist file, main character energy fr fr 🔥
