Ruby extension not working

[vinayb21]

I installed the ruby extension for theia @theia/ruby but neither the linting nor the autocomplete is working for ruby.
Other languages like Java, Python etc. are working fine.

Also I am getting the following warning message
"The directory referenced by local-dir:../../plugins does not exist." when I start the browser Theia application.

"The directory referenced by local-dir:../../plugins does not exist." when I start the browser Theia application.

it is unrelated

Do you have package.json of your app? Installing @theia/ruby extension within Theia repo won't work.

As i said it cannot work witinin Theia repo. @theia/ruby depends on published @theia/core@latest which is different from local @theia/core. Do yarn why @theia/core and you will see that you get 2 of them, not one.

Follow https://www.theia-ide.org/doc/Composing_Applications.html, replace next with latest, and add @theia/ruby extension, such app should be built properly.

Will try it. Thanks for the help though.

@vinayb21 thanks for reporting

ruby extension is broken:

Someone has to update it to latest APIs: https://github.com/theia-ide/theia-ruby-extension

Unfortunately, we always publish against @theia/core@laltest. We MUST publish external extensions against proper core version not latest, i.e. @theia/core@^0.3.19. Right now there is no working version of @theia/ruby even for 0.3.18.

//cc @svenefftinge @marcdumais-work

[vinayb21]

Thanks for confirming.

[svenefftinge]

There has been no 'latest' release of the ruby-extension.
You need to use next tag instead.
closing this in favor of theia-ide/theia-ruby-extension#7

Hello @vinayb21 ,
Can you guide me to get autocomplete features for java/python language?
What I did: I just added "@theia/java":"next" and "@theia/python":"next" in my package.json. and ran "yarn" and "yarn theia build" and started theia. When I start a java project I get an error saying : "languages ERROR Error occurred while starting language contribution. /services/languages/java/:id. Error: The Java server launcher is not found".
When I start a python project, I don't get anything on pressing Ctrl+space. Is there anything I need to do?
