Language server error: Failed making directory even after creating parent directories about tabnine-vscode

[lalten]

Aha, apparently TabNine will only detect a project_root if there is a .tabnine_root or .git: codota/TabNine#5

a git init in /tmp/vscode-tabnine actually did the trick 😆

If this is intended behaviour, it should clearly be mentioned somewhere in TabNine's docs.

I just tried with ccls and it has a similar error:

I have the impression that the ${project_root} variable doesn't correctly expand when starting the server. That would explain why it tries to "initialize in directory /tmp/vscode-tabnine/myfile.cpp", which is not a directory but a file. Of course this won't work.

Where, and to what value is ${project_root} set? I tried to change the toml to use vscode's ${workspaceFolder}, but that didn't help and I'm not sure it would work anywhere outside launch.json and tasks.json files...

Also see codota/TabNine#119, which seems to be related
