The bad news: Google decided to kill PNaCl, and from 2018 it will be dropped from its browsers. So, we’ll
stop producing pnacl packages at some point. It’s a shame because the technology is good and it
supports better performance.

The good news: a web-assembly (WASM) build of Csound has been developed (thanks to hfmanson who
produced a build script for us). It uses the same model as js csound and very similar infrastructure,
so it’s a drop-in replacement for it.

I have tested the builds with trapped and the performance is as follows:

1. benchmark (native): 2.9s
2. PNaCl: 3.6s
3. JS: 13s
4. WASM: 6.4s

So it’s not as good pnacl, but it’s twice as fast as the JS version. It’s not as good for RT audio
either as it depends on Web Audio, which is still pretty awful.

As with many technologies in the past, the superior version (PNaCl) was not the one to be
adopted generally.

Anyway, at least we have a way of ensuring the continuation of Web-based Csound.

Thanks for the update! I've been considering Web based Csound again, though I never got my head round pnacl... So you can akready use Csound with java script? My Web application isn't real time, so that might be a good easy way for me to realise my plans

I’ve put up a simple example at

https://csound.github.io/wasm

tested on the latest chrome (59), but I believe it will run on firefox 52 as well.

Works for me, Chrome 58.0.3029.110 (64-bit) on Ubuntu 16.04. As I said
before, great! What I want to do now is:

(1) Get the toolchain set up so I can build this and contribute to this.

(2) Ensure that the Csound API used by csound.node also works in
Csound for WASM.

(3) Port some additional goodies into Csound for WASM.

It's too bad about PNaCl, which worked just great, but it is what it
is. But csound.node definitely runs at native speed because it is
native.

Thanks,
Mike

For (1) it’s very simple, just the latest Emscripten, but make sure all the installation instructions
are followed up. To build it, the scripts in the csound repo should work for unix shells, but you
should be able to adapt them for Windows. The README.md lists the order in which things
should be done.

The example in example-wasm works partially (I can’t get the MIDI example to work but have
not investigated). However, I find it too complicated and full of extras, so I am starting to build a collection of
simpler single-file scripts to test and give a more graduated introduction to this code. The
first one is the one I put up. This should help you with (2).

Shame we’re too late for this year's WAC. It would have been good to show Csound off a little.

Hi,

I probably need an update of the browsers,

Mine Firefox  51.0.1 (that I cannot update due to some plugins that are broken 
with later versions) and Chrome 55 

both stop at state "loading... " on the screen an javascript console reports:

uncaught exception: no binaryen method succeeded. consider enabling more 
options, like interpreting, if you want that: https://github.com/kripken/
emscripten/wiki/WebAssembly#binaryen-methods

Jut to let know, this is not a problem, I need to update.

Thank you!

tarmo

Btw I’ve added a new example, adapted from PNaCl Csound. It wasn’t difficult to adapt it.

I have installed the WebAssembly toolchain on my Linux computer, run
the build scripts, and got Csound to play "Trapped" in my browser.

There are a couple of minor irritations that I will fix or document.
On the whole it was painless.

Thanks again to hfmanson, Victor, and anyone else who made this possible.

As I did for the PNaCl build, I will add some of the plugin C++
opcodes to be statically linked into the WebAssembly build of the
Csound library. I will also try to port my examples at
gogins.github.io to use WebAssembly instead of PNaCl. Some of these
are full-scale pieces with visuals that have been performed.

Regards,
Mike

I have ported the csound.js frontend from PNaCl csound and added some examples from the
PNaCl collection (to the wasm subdirectory). It’s now fairly simple to port/adapt code that used
to run with PNaCl to run with WASM.

I’ve added some extra functionality to CsoundObj, including a means of freeing up memory,
which wasn’t there (I expect that the code was leaking memory without it, but now it should be
OK, provided that the CsoundObj gets destroyed explicitly).

How do I install WebAssembly on OS X?

The web page says use brew, but it does not show the exact line...
I tried:

brew install webassembly

and got:

Error: No available formula with the name "webassembly"
==> Searching for a previously deleted formula...
Warning: homebrew/core is shallow clone. To get complete history run:
   git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.

Confusing, since on the original website it says to install webassembly 
first and then emscripten, it seems.
Anyway, I can't get past the first command (emsdk update):

RMA:emsdk-portable richard$ ./emsdk update
Traceback (most recent call last):
   File "./emsdk", line 2199, in 
     sys.exit(main())
   File "./emsdk", line 1853, in main
     if len(sys.argv) <= 1 or sys.argv[1] == 'help' or sys.argv[1] == 
'--help':
TypeError: object of type 'filter' has no len()

I guessed it had to do with my default Python version (3.5). I changed 
the first line in emsdk to use python2.7 and got a bit further.
But on the command 'emsdk install latest' it failed:
..
Installing SDK 'sdk-1.37.13-64bit'..
Installing tool 'clang-e1.37.13-64bit'..
HTTP error with URL 
'https://s3.amazonaws.com/mozilla-games/emscripten/packages/llvm/tag/osx_64bit/emscripten-llvm-e1.37.13.tar.gz':

Installation failed!

Ok, I had to use these commands to get rid of that:

./emsdk install sdk-1.37.12-64bit
./emsdk activate sdk-1.37.12-64bit

it is now installed

I tried to execute the download_and_install script. To my surprise, OS X 
does not come with wget, so had to install that first.
Now I get:

libsndfile-1.0.25.tar.gz 
100%[==========================================================================>] 
1.01M  1.30MB/s    in 0.8s

2017-06-11 14:55:09 (1.30 MB/s) - ‘libsndfile-1.0.25.tar.gz’ saved 
[1060692/1060692]

./download_and_build_libsndfile.sh: line 8: ../patches/sndfile.c.patch: 
No such file or directory
./download_and_build_libsndfile.sh: line 13: emconfigure: command not found
./download_and_build_libsndfile.sh: line 14: emmake: command not found
./download_and_build_libsndfile.sh: line 15: cd: ./src/.libs: No such 
file or directory

Do I have to copy the csound emscripten folder to my enscripten folder, 
or the whole csound folder?

Not sure what goes wrong now. I get:

RMA:1.37.12 richard$ sudo ./download_and_build_libsndfile.sh
./download_and_build_libsndfile.sh: line 13: emconfigure: command not found
./download_and_build_libsndfile.sh: line 14: emmake: command not found
./download_and_build_libsndfile.sh: line 15: cd: ./src/.libs: No such 
file or directory

I already changed emconfigure and emmake to use python2.7.
The download script calls emconfigure and emmake without './' preceding 
it, so I changed that. Then I get:

RMA:1.37.12 richard$ sudo ./download_and_build_libsndfile.sh
./download_and_build_libsndfile.sh: line 13: ./emconfigure: No such file 
or directory
./download_and_build_libsndfile.sh: line 14: ./emmake: No such file or 
directory

But executing the line on its own it tries to do something:
RMA:1.37.12 richard$ ./emconfigure ./configure --enable-static 
--disable-shared --disable-libtool-lock --disable-cpu-clip 
--disable-sqlite --disable-alsa --disable-external-lib$
ERROR:root:Exception thrown when invoking Popen in configure with args:

Traceback (most recent call last):
   File "./emconfigure", line 13, in

   File

line 1487, in configure
     process = Popen(args, stdout=None if EM_BUILD_VERBOSE_LEVEL >= 2

line 1326, in _execute_child
     raise child_exception

It looks like there is no 'configure' directory??

This one, but I think I have read it wrong. It actually starts with 
compiling emscription, to the impression rises that emscription IS 
webassembly...

I followed these steps and emscription works. I compiled this nice 
little GUI package with it. 
https://medium.com/@shiyan/rejuvenate-my-old-opengl-gui-with-webassembly-1d46a6baa52e 
and it runs in the browser.

My problem is that that the csound instructions are not clear. Does the 
'download_and_install' script do all the work or do I have to clone the 
csound/emscription folder also into my local emscription folder?

All you need to do is run the scripts as in the instructions (of course, assuming you have the latest sources from git develop). 
Nothing else. With Emscripten properly installed, it will compile everything.  That’s what I did here.

The errors below are saying that emscripten is not properly installed or configured, because the script can’t find the commands.

Did you read the part about paths and 'source emsdk_set_env.sh' ? (The script name may be emsd_env.sh, I forget which is the one to run). This is mentioned in the emscripten manual as well as by the emsdk too after you install and activate the tools.

You get the csound sources from git and then follow the instructions in the emscripten/README.md file of the csound
sources. Make sure that the Emscripten toolchain is fully installed and that all the paths are set correctly to the Emscripten
binaries. Half-installed with nothing of their bin directories in your PATH will not work, so you need to complete all 
steps in the Emscripten instructions.

Yes, I've done that several times. The output looks OK:

RMA:emsdk-portable richard$ source ./emsdk_env.sh
Adding directories to PATH:
PATH += /Users/richard/Downloads/emsdk-portable
PATH += /Users/richard/Downloads/emsdk-portable/clang/e1.37.12_64bit
PATH += /Users/richard/Downloads/emsdk-portable/node/4.1.1_64bit/bin
PATH += /Users/richard/Downloads/emsdk-portable/emscripten/1.37.12

Setting environment variables:
EMSDK = /Users/richard/Downloads/emsdk-portable
EM_CONFIG = /Users/richard/.emscripten
BINARYEN_ROOT = /Users/richard/Downloads/emsdk-portable/clang/e1.37.12_64bit/binaryen
EMSCRIPTEN = /Users/richard/Downloads/emsdk-portable/emscripten/1.37.12

Did you read the part about paths and 'source emsdk_set_env.sh' ? (The script name may be emsd_env.sh, I forget which is the one to run). This is mentioned in the emscripten manual as well as by the emsdk too after you install and activate the tools.

Ok, but what sources and where do I put them? Do I need the whole csound
folder from git or just the emscripten folder?

Yes, I've done that several times. The output looks OK:

Did you read the part about paths and 'source emsdk_set_env.sh' ? (The script name may be emsd_env.sh, I forget which is the one to run). This is mentioned in the emscripten manual as well as by the emsdk too after you install and activate the tools.

Ok, but what sources and where do I put them? Do I need the whole csound

I installed emscription again, following the exact steps. Like yesterday 
I had to get an earlier version:

./emsdk install sdk-1.37.12-64bit
./emsdk activate sdk-1.37.12-64bit

(I also had to change the python version in emsdk to 2.7, since my 
default version is 3.5)

I aslo did the source command and it seemed ok:
Done installing tool 'emscripten-1.37.12'.
Done installing SDK 'sdk-1.37.12-64bit'.
RMA:emsdk-portable richard$ ./emsdk activate sdk-1.37.12-64bit
Writing .emscripten configuration file to user home directory 
/Users/richard/
The Emscripten configuration file /Users/richard/.emscripten has been 
rewritten with the following contents:

import os
LLVM_ROOT='/Users/richard/Downloads/emsdk-portable/clang/e1.37.12_64bit'
EMSCRIPTEN_NATIVE_OPTIMIZER='/Users/richard/Downloads/emsdk-portable/clang/e1.37.12_64bit/optimizer'
BINARYEN_ROOT='/Users/richard/Downloads/emsdk-portable/clang/e1.37.12_64bit/binaryen'
NODE_JS='/Users/richard/Downloads/emsdk-portable/node/4.1.1_64bit/bin/node'
EMSCRIPTEN_ROOT='/Users/richard/Downloads/emsdk-portable/emscripten/1.37.12'
SPIDERMONKEY_ENGINE = ''
V8_ENGINE = ''
TEMP_DIR = '/var/folders/r0/103fxm8x32j76d1yv589d0jc0000gn/T'
COMPILER_ENGINE = NODE_JS
JS_ENGINES = [NODE_JS]

To conveniently access the selected set of tools from the command line, 
consider adding the following directories to PATH, or call 'source 
./emsdk_env.sh' to do this for you.

/Users/richard/Downloads/emsdk-portable:/Users/richard/Downloads/emsdk-portable/clang/e1.37.12_64bit:/Users/richard/Downloads/emsdk-portable/node/4.1.1_64bit/bin:/Users/richard/Downloads/emsdk-portable/emscripten/1.37.12
RMA:emsdk-portable richard$ source ./emsdk_env.sh
Setting environment variables:
EMSDK = /Users/richard/Downloads/emsdk-portable

But then I ran the download and build script :

RMA:emscripten richard$ sh download_and_build_libsndfile_wasm.sh
download_and_build_libsndfile_wasm.sh: line 13: emconfigure: command not 
found
download_and_build_libsndfile_wasm.sh: line 14: emmake: command not found
cp: ./src/.libs/libsndfile.a: No such file or directory
RMA:emscripten richard$ emmake

I have not change emconfigure and emmake to use python 2.7 yet, maybe I 
should, although it says it should work with python 2 and 3...

Frustrating....

I installed 'latest' and then activated 'latest',
maybe that is a difference?
In any case, the script can't find the emscripten tools, as if they were not in your path, did you check it?

echo $PATH

see if the relevant dirs are there.

emsdk list

should also list your installed and active versions.

FWIW I also had problem getting this to build for me. I wanted to investigate how easy it would be to add the -F/--midi-file command line flag for remote files. I think it would be neat, but I don't know how hard it would be to implement.

I installed emscription again, following the exact steps. Like yesterday I had to get an earlier version:

./emsdk install sdk-1.37.12-64bit
./emsdk activate sdk-1.37.12-64bit

(I also had to change the python version in emsdk to 2.7, since my default version is 3.5)

I aslo did the source command and it seemed ok:
Done installing tool 'emscripten-1.37.12'.
Done installing SDK 'sdk-1.37.12-64bit'.
RMA:emsdk-portable richard$ ./emsdk activate sdk-1.37.12-64bit
Writing .emscripten configuration file to user home directory /Users/richard/
The Emscripten configuration file /Users/richard/.emscripten has been rewritten with the following contents:

JS_ENGINES = [NODE_JS]

To conveniently access the selected set of tools from the command line, consider adding the following directories to PATH, or call 'source ./emsdk_env.sh' to do this for you.

/Users/richard/Downloads/emsdk-portable:/Users/richard/Downloads/emsdk-portable/clang/e1.37.12_64bit:/Users/richard/Downloads/emsdk-portable/node/4.1.1_64bit/bin:/Users/richard/Downloads/emsdk-portable/emscripten/1.37.12
RMA:emsdk-portable richard$ source ./emsdk_env.sh
Setting environment variables:
EMSDK = /Users/richard/Downloads/emsdk-portable

But then I ran the download and build script :

RMA:emscripten richard$ sh download_and_build_libsndfile_wasm.sh
download_and_build_libsndfile_wasm.sh: line 13: emconfigure: command not found
download_and_build_libsndfile_wasm.sh: line 14: emmake: command not found
cp: ./src/.libs/libsndfile.a: No such file or directory
RMA:emscripten richard$ emmake

I have not change emconfigure and emmake to use python 2.7 yet, maybe I should, although it says it should work with python 2 and 3...

Frustrating....

You get the csound sources from git and then follow the instructions in the emscripten/README.md file of the csound
sources. Make sure that the Emscripten toolchain is fully installed and that all the paths are set correctly to the Emscripten
binaries. Half-installed with nothing of their bin directories in your PATH will not work, so you need to complete all
steps in the Emscripten instructions.

All you need to do is run the scripts as in the instructions (of course, assuming you have the latest sources from git develop).
Nothing else. With Emscripten properly installed, it will compile everything.  That’s what I did here.

The errors below are saying that emscripten is not properly installed or configured, because the script can’t find the commands.

I followed these steps and emscription works. I compiled this nice little GUI package with it. https://medium.com/@shiyan/rejuvenate-my-old-opengl-gui-with-webassembly-1d46a6baa52e and it runs in the browser.

My problem is that that the csound instructions are not clear. Does the 'download_and_install' script do all the work or do I have to clone the csound/emscription folder also into my local emscription folder?

It looks like there is no 'configure' directory??

Do I have to copy the csound emscripten folder to my enscripten folder, or the whole csound folder?

Confusing, since on the original website it says to install webassembly first and then emscripten, it seems.
Anyway, I can't get past the first command (emsdk update):

I guessed it had to do with my default Python version (3.5). I changed the first line in emsdk to use python2.7 and got a bit further.
But on the command 'emsdk install latest' it failed:

I have ported the csound.js frontend from PNaCl csound and added some examples from the
PNaCl collection (to the wasm subdirectory). It’s now fairly simple to port/adapt code that used
to run with PNaCl to run with WASM.

I’ve added some extra functionality to CsoundObj, including a means of freeing up memory,
which wasn’t there (I expect that the code was leaking memory without it, but now it should be
OK, provided that the CsoundObj gets destroyed explicitly).

I have installed the WebAssembly toolchain on my Linux computer, run

There are a couple of minor irritations that I will fix or document.
On the whole it was painless.

Thanks again to hfmanson, Victor, and anyone else who made this possible.

As I did for the PNaCl build, I will add some of the plugin C++
opcodes to be statically linked into the WebAssembly build of the
Csound library. I will also try to port my examples at
gogins.github.io to use WebAssembly instead of PNaCl. Some of these
are full-scale pieces with visuals that have been performed.

I probably need an update of the browsers,

Mine Firefox  51.0.1 (that I cannot update due to some plugins that are broken

both stop at state "loading... " on the screen an javascript console reports:

uncaught exception: no binaryen method succeeded. consider enabling more

Jut to let know, this is not a problem, I need to update.

Thank you!

The bad news: Google decided to kill PNaCl, and from 2018 it

will be dropped from its browsers. So, we’ll stop producing pnacl
packages at some point. It’s a shame because the technology is good and
it supports better performance.

The good news: a web-assembly (WASM) build of Csound has been developed
(thanks to hfmanson who

produced a build script for us). It uses the

same model as js csound and very similar infrastructure, so it’s a
drop-in replacement for it.

I have tested the builds with trapped and the performance is as follows:

1. benchmark (native): 2.9s
2. PNaCl: 3.6s
3. JS: 13s
4. WASM: 6.4s

So it’s not as good pnacl, but it’s twice as fast as the JS version. It’s
not as good for RT audio

either as it depends on Web Audio, which is

still pretty awful.

As with many technologies in the past, the superior version (PNaCl) was
not the one to be

adopted generally.

Anyway, at least we have a way of ensuring the continuation of Web-based
Csound.

Be sure to do the source of the env.sh script within the terminal before you run any of our build scripts. That sourcing has to be done every time either by hand or by modifying your shell startup (as noted in the emsdk output). (Those paths are not permanently changed when you source the shell script.)
