.. role:: ref(emphasis)
.. _futhark-wasm(1):
============
futhark-wasm
============
SYNOPSIS
========
futhark wasm [options...] <program.fut>
DESCRIPTION
===========
``futhark wasm`` translates a Futhark program to sequential
WebAssembly code by first generating C as ``futhark c``, and then
using Emscripten (``emcc``). This produces a ``.js`` file that allows
the compiled code to be invoked from JavaScript. Executables
implement the Futhark server protocol and can be run with Node.js.
OPTIONS
=======
Accepts the same options as :ref:`futhark-c(1)`.
ENVIRONMENT VARIABLES
=====================
``CFLAGS``
Space-separated list of options passed to ``emcc``. Defaults
to ``-O3 -std=c99`` if unset.
``EMCFLAGS``
Space-separated list of options passed to ``emcc``.
EXECUTABLE OPTIONS
==================
The following options are accepted by executables generated by
``futhark wasm``.
-h, --help
Print help text to standard output and exit.
-D, --debugging
Perform possibly expensive internal correctness checks and verbose
logging. Implies ``-L``.
-L, --log
Print various low-overhead logging information to stderr while
running.
SEE ALSO
========
