Hi All,
i'm a very basic knowledge about html and javascript and i was reading the post about csound webassembly.
What i would like to ask is for a really really simple example because looking at csound emscripten folder I see
too much for my little brain.
I have built webassembly csound (is that correct?) following the instructions in emscripten folder and I am able
to play with examples but now I would like to write somethings to my own.
So can I have only an index.html file that "import" libcsound.js? Or what i need to do?
Any help, hint or how to look is really appreciated.

Thanks,
ciao,
francesco.

I will add to the emscripten/README.md file a very basic working
example with sufficient explanation of what is going on. There are
working examples scattered about but, as you say, no clear, easy to
follow minimal example in an obvious place.

Regards,
Mike

I have done as you asked, more or less.

To make a simple obvious example work, I had to slightly modify the
Csound C and JavaScript sources a little in the
https://github.com/csound/csound/tree/develop/emscripten directory, so
Csound for WebAssembly has to be rebuilt before my example
(https://github.com/csound/csound/blob/develop/emscripten/examples-wasm/minimal.html)
will work. My changes were to enable csoundCompileCsdText to work in
the WebAssembly build.

However, there is a running version of the example (with a rebuilt
version of Csound for WebAssembly) in my own repository at
https://gogins.github.io.

This example will probably run for you from here:
https://gogins.github.io/csound/wasm/minimal.html. It's fairly
self-explanatory and you can examine the source code.

Regards,
Mike

What kind of sorcery is this? I opened the html in vanilla Firefox,
Linux and it worked without me having to install any extra web
component. Are we already living in the future? Congratulations to all
the people working on this!

It also (almost sort of) worked on my Android device, but Xanadu seems
to be a little too much for it.

Cheers.

indeed! the same here. guys, could you please slow down a little bit until
guys like me can catch up with all the recent developments?

WebAssembly has the potential to change the world of software in some
significant ways -- if it is widely adopted and if it proves to be
secure.

WebAssembly already has been widely adopted by the W3C standards group
and by the major browsers. If it is widely adopted by software
developers AND if it proves to be secure, then fairly quickly I would
expect all "native execution" environments (Java applets, Netscape
plugins, other binary plugin formats, PNaCl, Emscripten) on the Web to
be replaced by WebAssembly. This could happen over just the next year
or two.

The main reason for WebAssembly to be used instead of Java applets or
other native execution environments is security. But security truly is
a big deal. WebAssembly runs in the same security sandbox as Web pages
and their associated JavaScript. Standardization is also a big deal.

WebAssembly also is designed to run on servers and desktops, as
JavaScript now does in node.js and NW.js.

What this means for Csound is that, potentially, the existing AT LEAST
SIX ways of running HTML5 with Csound (Csound for Android,
csound.node, the qthtml branch of CsoundQt, Csound for PNaCl, Csound
for Emscripten, there may be more, and of course Csound for
WebAssembly) could be replaced by JUST ONE (Csound for WebAssembly).
For example, the current version of NW.js is said to support
WebAssembly.

This would free up a significant amount of time for Csound developers.

But the most important thing is that with WebAssembly, Csound will be
running in the most widely used development environment in the world
-- the HTML5 environment. JavaScript acts as "glue" that will enable
Csound to be used with virtual reality, databases, position sensors,
math typesetting, 3D animation, MIDI, styleable user interfaces, and
all the other capabilities that are a standard part of HTML5, not to
mention other libraries that will now start being ported to
WebAssembly, such as game engines.

I'd like to thank (in no particular order) Steven Yi, Victor
Lazzarini, hfmanson, Edward Costello, and others who made this
possible.

Regards,
Mike
