Language Server

[glenn2223]

Issues

Currently, there is no way of knowing that your SASS is invalid until you save. Other tools update the UI and highlight issues

Proposal

Create a language server utility which is called by the onDidChangeTextDocument event. But, we only catch errors out not compile anything

Keeping #300 in mind, maybe compilation errors are disabled if the user has the language server enabled

TODO

• Research the language server best implementation
• See if we can output all errors and not just stop at the first (like it does with compilation)
• Ensure the method is called on the onDidChangeTextDocument event
• Ensure the UI is updated with the red error wiggly underscores
• See if the autosave limitations (constant error popup) can be addressed
