Errors with .fsx files #29

Tried to work with FAKE script.

It would be super helpful if you could make a minimal example that reproduces the problem.

@georgewfraser
I've got the problem by simply creating a test.fsx file

Output from "F# Language Server":

Can't find symbols in test.fsx because of error in project options

Same Problem here. Creating the missing 'assembly' path seems to solve the issue.

isaacabraham · 2019-01-03T16:26:17Z

Same issue here, clean install and open up an fsx.

georgewfraser · 2019-01-08T09:46:33Z

I think this is windows-specific so I am having trouble reproducing it. Assuming this is only affecting .fsx files, the root of the problem is probably in the function that infers compiler options for .fsx files:

https://github.com/georgewfraser/fsharp-language-server/blob/853ba305dd23c5580bb046645dff6262aa7637b2/src/FSharpLanguageServer/ProjectManager.fs#L239

It would help to figure this out if someone posted the entire log.

SchlenkR · 2019-01-10T03:46:03Z

Log is here:

log.txt

If you have a look at the stack trace, you see that that there is a Problem inside here:

https://github.com/Microsoft/visualfsharp/blob/9b55eccd1bc83ed123c5ae08c577be5646861830/src/fsharp/SimulatedMSBuildReferenceResolver.fs#L141-L146

It seems that the internal SimulatedMSBuildReferenceResolver is assuming the existence of the mentioned and missing 'assembly' folder. Unfortunately, the stack trace ends there and I cannot see the original Code invoking it. Maybe it's the piece of Code you cited above.

Is there a way of Debugging the language Server? Maybe starting it out of VS with a Debugger attached and send a specific stdin to it?

georgewfraser · 2019-01-12T04:17:43Z

Yes you should be able to attach a debugger. You can change the command that is used to launch fsharp-language-server right here:

https://github.com/georgewfraser/fsharp-language-server/blob/58bc398291dcd141d88770c458ad75b4d97bcb3e/client/extension.ts#L21

Then hit F5 in vscode to run the extension out of your working directory. Then attach to the running process.

georgewfraser · 2019-01-27T05:34:59Z

Still can't reproduce this on Mac, unfortunately : (

Give the stack trace, this looks a bit like a problem originating in FSharp.Compiler.Service. @ronaldschlenker you might be able to reproduce this without fsharp-language-server by creating FSharp.Compiler.Service with the options:

I try starting with it today...

georgewfraser · 2019-01-27T20:03:33Z

The other option is to just add the missing path src\FSharpLanguageServer\bin\Release\netcoreapp2.0\assembly to the build. It's pretty klugey and I'm a little concerned it would be brittle, because we don't know why it works, but if @ronaldschlenker doesn't have success reproducing the problem I'm inclined to just do that.

SchlenkR · 2019-01-27T22:53:58Z

Finally, I am able to reproduce the issue in the Debugger, @georgewfraser.
The error comes from here:

https://github.com/georgewfraser/fsharp-language-server/blob/7ce8866f89651a3c7dd99400376fb9516712c85b/src/FSharpLanguageServer/ProjectManager.fs#L242

Next step is to create a project where I can isolate the issue. In the meanwhile, your suggested workaround seems reasonable to have a working build on Windows until the root cause is identified.

I continue working on it...

georgewfraser · 2019-01-27T23:04:25Z

Would someone on this thread please clean-install the latest version 0.1.22 and confirm that the workaround is effective?

SchlenkR · 2019-01-28T07:59:05Z

I can confirm it, executing the following steps (VSCode + Windows):

Uninstall the Extension and close vscode
Remove all georgewfraser.fsharp-language-server-0.1.xxx folders from the vscode extension folder
Open vscode and reinstall

Result:

I can see that the Assembly Folder with the readme.md is present.
There is no error in the Output and in the Editor, everything works fine.

SchlenkR · 2019-01-29T20:04:48Z

@georgewfraser I think I found the issue, and it's something that should be fixed inside FSharp.Compiler.Service.

I raised this issue: dotnet/fsharp#6161

I don't see a possibility this can be fixed here.

georgewfraser · 2019-01-30T22:02:08Z

Thanks @ronaldschlenker ! Hopefully the dumb workaround where we add the missing folder will fix this for now.
