	Dear list! I was browsing the manual and found -G, --postscriptdisplay Suppress graphics, use PostScript displays instead. -g, --asciidisplay Suppress graphics, use ASCII displays instead. which made me wonder if there is a way of displaying graphics using something other than ASCII or PostScript? Ideally I would love to have a simple fltk-panel where e.g. fft-curves, f-table contents and linseg/expseg shapes could be displayed and updated continuously. Is there such a thing, or would it be worth filing a feature request :-)? Regards, Anders

	If you are familiar with HTML5 there are new websocket opcodes (in git but not release yet) that will send any type (Arrays or variables) of any size to the browser. This allows you to do an FFT, find the magnitudes and render them in a canvas giving you a serviceable spectrogram. This also works in real time for dynamically updating the spectrogram.

	Lol :), cool if you need any help let me know, there is a manual entry in the manual git repo here in xml, but it should be pretty readable https://github.com/csound/manual/blob/44a2526a7d2d5dba1a551c164a62747ebae97662/opcodes/websocket.xml, there is also an example html file here: https://github.com/csound/manual/blob/13b6b2fe57c0dcc4f979b54f1c4509548ba9aecd/examples/websocket.html with accompanying csd file here https://github.com/csound/manual/blob/13b6b2fe57c0dcc4f979b54f1c4509548ba9aecd/examples/websocket.csd I also find that using this opcode it can be a good idea to make a script that refreshes the web page you are using and call it when csound starts, this can be accomplished using the system opcode.

	Websockets allow you to send data pretty fast from other programs to the browser, which can then be read via Javascript. Yeah it depends on libwebsockets https://libwebsockets.org/trac/libwebsockets , I think thats available for Linux.

	Hi, I built libwebsockets from source (see https://libwebsockets.org/trac/libwebsockets ) - it depends on openSSL and its devel packages. It went flawlessly, After that the csound websocket opcode was built fine and the example wesocket.html / websocket.csd worked as expected. Indeed, I needed to reload the webpage after csound was started (Perhaps there could be just a Connect button on that page? ) But if did not load the html page, I got a myriad of messages to the console from csound: websocket: variable klfo data not sent,buffer overrrun - perhpas you can have a look? But otherwise - exciting! I try to test it with different solutions - so far I have always written a host in C++ that handles the websocket traffic and I try to see, if I can abandon it with the websocket opcode.

	Hey, Tarmo, what is happening there i think is that Csound is sending the klfo messages to the browser before the socket has connected, this will cause a buffer overrun because the values are not being read out of the buffer on the browser side. What I do is use the system opcodes outside of an instrument to call a script that refreshes my web page before the instruments can run. Anders, I'm not sure what could be going wrong but perhaps libwebsocketIO has not linked to libwebsockets correctly, can you do a pastebin/gist of the build output from CMake?

	Also what version of libwebsockets are you using? Perhaps the websocket opcode is using a function from a newer/older version of the library.

	Looks like libwebsocket_cancel_service was added to the library with this commit https://www.openhub.net/p/libwebsockets/commits/346545359, does your version predate that?

	Got it working!! I Ubuntu 14.04 seems to install libwebsockets 1.2.2 from repositories, whereas when the latest release is 1.4. After building libwebsockets from source and putting a soft link in /usr/lib/x86_64-linux-gnu/ where cmake looks for it, I got it all splendidly! Thank you Ed (and Tarmo for indirectly prompting me to build libwebsockets from source)! Now for some exploration...

	It seems the earliest release of libwebsockets that could include libwebsocket_cancel_service is 1.3, comitted 13 months ago. Maybe there could be a specific dependency stated for cmake?

It went flawlessly, After that the csound websocket opcode was built fine and the example wesocket.html / websocket.csd worked as expected. Indeed, I needed to reload the webpage after csound was started (Perhaps there could be just a Connect button on that page? ) But if did not load the html page, I got a myriad of messages to the console from csound: websocket: variable klfo data not sent,buffer overrrun - perhpas you can have a look? But otherwise - exciting! I try to test it with different solutions - so far I have always written a host in C++ that handles the websocket traffic and I try to see, if I can abandon it with the websocket opcode.

	In order to get the page to refresh just once I run a script that I call using the system opcode outside any instruments, just before instrument 1, this works fine for me, its just a bit tricky writing scripts that do such things, at least on the Mac, maybe it's easier on Linux.

	Everything is received as a Float64Array in the browser, k-vars are just Float64Arrays with 1 value, a-vars are arrays with ksmps values. All arrays though are 1 dimensional so a 2d k-array that is 2 * 5 will be recieved in the browser as a Float64Array with 10 values.
