FileSystemNotFound: Provider not installed

[tdroxler]

Weird issue in vscode when opening the Source Control tab

I could reproduce with the following:

git clone git@github.com:alephium/alephium-nft.git
cd alephium-nft
code .

Make a change to any contract, like just a new line.

Open the source control: Ctrl + Shift + G

From the source control tab, click on your contract

The error should pop up.

I didn't have time to check what was received by the server, but maybe the didOpen notification send something with an uri starting with git/// instead of the expected file///

Yep, you are right. Good catch! URIUtil.getFileName errored (stacktrace from VSCode below). It errors for all APIs: open, code-completion, go-to def etc because git is not a supported URI yet.

This will have to be handled differently. I don't have a quick solution for this and it will need testing, specially for moved files. So temporarily, to stop that error, we can ignore processing files that do not have a file:/// scheme. WDYT?

We can ignore processing files that do not have a file:/// scheme. WDYT?

Yes, anyway I don't think ralph-lsp should handle in anyway a git:/// file. We do receive them because we tell the client we want to watch all files, we could also choose to watch only *.ral, ralph.json and alephium.config.ts. The client then shouldn't send us the git files.

But It's still good to ignore other schemes, because a client could also send us something we didn't request
