How to implement a Custom CodeActionProvider?

[rhumbertgz]

Hi,

Does anyone have implemented a custom CodeActionProvider?

Is there an example available?

Thanks,
Humberto

Hey @rhumbertgz,

we have an example in the langium grammar language. The idea is just to switch over some attribute of the diagnostic (we use the code, but you can use data as well) and return a code action where necessary.

Thanks for the pointer @msujew 👍🏼

@msujew I was able to implement my custom CodeActionProvider based on the example that you mentioned, thanks again. But 😀, I noticed that code action icon 💡 is not not displayed.

Any suggestions?

You can find the example here:

Using the react component the quick action is displayed as aspected. It seems I missing some setting here.

Does it make a difference if you set isPreferred to true?

@spoenemann I had already the property isPreferred to true. I basically copy-paste my action provider. I tried to disable some properties of the UserConfig looking for the one activating the icons, but nothing worked. At least, it works perfect on my real project :). Thanks anyways!
