how to enable checking all files in VSCode?

[lukepighetti]

hey all. noticing that biome only seems to check files that are an open tab in vscode. my expectation is that all linter warnings show up in problems tab without having to first open the files. this is how other languages like dart behave. wondering if this is a bug or if there's a setting to enable here?

It isn't a bug, and that's how the Biome Language Server works. Biome Language Server uses LSP https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/ and the specification doesn't have a spec to publish diagnostics for all files.

This feature may be provided by the extensions themselves, which might use some custom APIs of the editors.

If you want a feature like this, the editor extension should provide it.

If I understand correctly we can use the Workspace Diagnostics method to get diagnostics for all files: https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#workspace_diagnostic

Awesome! We could create an issue to track that

yeah i'm not well versed on the inner workings here but i believe the strategy the dart analyzer and VSCode extension use is to check all files when the LSP first launches in the current working directory (for us that's about 4 seconds, no problem) and then update when new tabs are opened. that keeps all issues in the project in the problem pane at all times which is super super useful
