CLI tools for interoperating with WebAssembly files
Documentation
Demangle Rust and C++ symbol names in the `name` section

Usage: wasm-tools demangle [OPTIONS] [INPUT]

Arguments:
  [INPUT]  Input file to process

Options:
  -o, --output <OUTPUT>  Where to place output
  -v, --verbose...       Use verbose output (-v info, -vv debug, -vvv trace)
      --color <COLOR>    Configuration over whether terminal colors are used in
                         output [default: auto]
  -t, --wat              Output the text format of WebAssembly instead of the
                         binary format
  -h, --help             Print help (see more with '--help')

Examples:

Suppose foo.wasm has the following textual representation:

(module
  (func $do_not_demangle_me)
  (func $_ZN4rustE)
  (func $_Z3food)
)

The second two functions are mangled Rust symbol names.

    # Demangle symbol names in foo.wasm and print the textual form of
    # the output to stdout.
    $ wasm-tools demangle -t foo.wasm
(module
  (type (;0;) (func))
  (func $do_not_demangle_me (;0;) (type 0))
  (func $rust (;1;) (type 0))
  (func $"foo(double)" (;2;) (type 0))
)

    # Demangle symbol names in foo.wasm and save the binary output
    # to foo-demangled.wasm.
    $ wasm-tools demangle foo.wasm -o foo-demangled.wasm

Exit status:
    0 on success,
    nonzero if the input file fails to parse.
