Me personally, no. But I hope other might be able-to
are there any browser extensions that use Theia?
Paul Maréchal
@realisation you should share your questions on https://spectrum.chat/theia.
On the other hand, I do not understand you question, using Theia you would create a full web application, as in: backend server + IDE in your browser, loaded like any other website

Is the concept of appState still in Che7?
Paul Maréchal
Sorry, I don't know, but this is Theia's Gitter, not Che's .

Hello Everyone!
I have created a plugin, and works fine in hosted mode. I take the .thea file, put it into a container with theia running, and a THEIA_PLUGINS variable set to the folder containing that .theia file, but theia doesn't see it? Am I missing something?
Stephen Raghunath
I also tried adding the plugins folder with the .theia file next to the package.json for the theia editor, but no luck

Hi, does anyone know how to add a button with function on the left bar of theia? thx!

Hi, I follow the example https://www.theia-ide.org/doc/Composing_Applications.html to create my own theia IDE. I want to add an extension to it but really don't know how to do.
After I copy the dependencies from package.json in https://www.theia-ide.org/doc/Authoring_Extensions.html example to my IDE's package.json, then using yarn to install the dependencies, it shows a lot of error message....
Does anyone know how to create an extension and add to IDE ? Thanks!

Error message:
"FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory"

@lihomahowareyou I find what is the problem, I should add the extension to package.json and put the extension folder to node_modules folder, thx!!

Hello :)
I've got a question about https://github.com/theia-ide/typescript-language-server, how to specify your own .tsconfig file there?
Vincent Fugnitto
Hi @kud, we've moved discussions to https://spectrum.chat/theia. I see you already opened the issue on https://github.com/theia-ide/typescript-language-server
Erwann Mest
Yep :D
I'm on spectrum too now
Do nmost VSC plugins work on Theia?
Marc Dumais
Hi @DouglasRMiles . Anecdotally, I would say yes. BTW, we have moved to Spectrum: https://spectrum.chat/theia?tab=posts . You should open a new topic there if you'd like to discuss this more.

Is there a lot of success with using the typescript-language-server (https://github.com/theia-ide/typescript-language-server) ?

If I run it with stdio and I issue a few commands, it shuts down after a few seconds without logging any error or warning.

I send initialize, and wait for reply, it replies correctly after sending a bunch of windows/log messages.
I then pause 5 seconds, it terminates the process.

If I don't pause and continue sending initalized, and then didOpen commands it crashes at about the same time distance into the overall runtime (5-6 seconds).

It is running on TS Server 3.7.3, Node 12.13.0, Mac OSX

THe tsls log shows no error and just has a last log message that appears normal, and the ti-NNNN.log says the parent process has exited, so shutting down.

Not sure where to look for potential problems. I'm manually sending only a few commands and it just dies.

Running with --sockets doesn't start up at all, so can't try that.

Node 10.x fails too.
