My visual code doeasn't interact with DAML types

Questions
1

Hi,

Looks like my VC doesn’t recognize my DAML env.

  • I can’t see types after hovering over the variable
  • I can’t see the grey script result when you write tests

This is my VS distribution:

image
image862×290 24.9 KB

This is my plugin

image1118×336 55.8 KB

My Java is 11.0.14
My daml is 2.2.0

Thanks

Please go to View -> Output and then select Daml Language Server in the drop down and show us the output here.

thanks for your help.
Another issue I have is that I can’t see the errors in real-time but only after running “daml build”.

5

Hm those logs look fine. Can you try creating a new project and testing in that:

daml new foobar
cd foobar
daml studio
6

In a new project, everything is fine.
I see both the types and the “Script results”.
So do I have to rebuild my project ???

did you see the second output results? there are a lot of error

7

Oh I missed the second part. So you’re somehow running out of memory. One option for that could be that one of your scripts produces an infinite loop or at least runs very long. You could selectively try to comment out certain scripts to narrow it down. If you can share your project we might also be able to point at the problematic code.

8

it happened just once.
Right now, I dont see those errors.but still, cant see the types and the “Script results”.

9

Try restarting the language server via Ctrl/Cmd-Shift-P → Reload Window.

10

Nope. Sorry…but it didnt help

11

Can you share your project? If the logs show no errors after a restart but you still don’t get script results, I don’t really know what could be going wrong.

@cocreature i maanged to get it working with “daml studio” command
