wasm2c - Man Page

• Convert a file to a C source file and header and display it to the console: wasm2c file.wasm

• Write the output to a given file (file.h gets additionally generated): wasm2c file.wasm -o file.c

tldr.sh

wasm2c takes a WebAssembly module and produces an equivalent C source and header.

The options are as follows:

--help

Print a help message

--version

Print version information

-v, --verbose

Use multiple times for more info

-o, --output=FILENAME

Output file for the generated C source file, by default use stdout

-n, --module-name=MODNAME

Unique name for the module being generated. This name is prefixed to each of the generaed C symbols. By default, the module name from the names section is used. If that is not present the name of the input file is used as the default.
