wasm2wat [options] file

wasm2wat does the inverse of wat2wasm, translate from the binary format back to the text format (also known as a .wat).

The options are as follows:

, --verbose
Use multiple times for more info
Print a help message
, --output=FILENAME
Output file for the generated wast file, by default use stdout
, --fold-exprs
Write folded expressions where possible
Experimental exception handling
Import/export mutable globals
Saturating float-to-int operators
Sign-extension operators
SIMD support
Threading support
Write all exports inline
Write all imports inline
Ignore debug names in the binary file
Give auto-generated names to non-named functions, types, etc.
Don't check for invalid modules

Parse binary file test.wasm and write text file test.wast

$ wasm2wat test.wasm -o test.wat

Parse test.wasm, write test.wat, but ignore the debug names, if any

$ wasm2wat test.wasm --no-debug-names -o test.wat
