Errors don't change on editing the file

[phenax]

Errors only show up when loading vscode for the first time. Consequent editing of the file doesn't seem to update the diagnostic info.

On opening vscode

On fixing the issue (expecting it to show the next error which is unused params)

Do you have running bsb -w process?

[phenax]

Yes. bsb from my node_modules is running

[phenax]

I had the same problem with vim-rescript (which uses rescript-vscode internally). In both those cases I get a prompt to start build after which I see a bsb process running in the background.

Version: 1.0.0 (also the recently released 1.0.1)

[chenglou]

Hello! Which bs-platform version?

[phenax]

bs-platform: 8.3.3

[chenglou]

Can you show me your lib/bs/.compiler.log?

[phenax]

lib/bs/.compiler.log

#Start(1607195542405)
#Done(1607195542441)

[chenglou]

Thanks. And I'm assuming you can repro this deterministically?

[phenax]

I created a blank (bs-platform + gentype) project with 1 rescript file and the plugin worked. But then I created a new angular project with ng new testproj and the issue showed up again. It seems to be running into issues with angular or maybe typescript dependencies.

[chenglou]

Not sure what you mean; our plugin doesn't work on angular files?

[phenax]

I meant rescript file inside an angular project

[phenax]

I've pushed a fresh angular project with one rescript file src/File.res that I could reproduce the issue with. The repo is at phenax/bug-repro-rescript-vscode

I have the same issue with plain ReScript (created with bsb -init foo -theme node). Compiler log does show the error but VSCode does not.

Restarting VSCode fixes the issue

if the error is shown, even deleting the code does not update:

@marcoemrich did you save the file?
I think I read somewhere the language server only works on saved files.

Edit: Found the source I read about that: ReScript Forum

[marcoemrich]

Yes - I use "save on focus lost", but also did save manually
