Comparison with Solargraph

[janko]

I'm pretty new to language servers, and I've been hearing only about Solargraph so far. Since this seems to be a replacement, it would be useful if the README included some advantages over Solargraph, to help developers decide 🙂

@janko Thank you for the suggestion. We have added an Overview to the README which describes the principles behind Ruby LSP, and highlights some of the main differences compared to Solargraph:

This part seems gone from the README and https://shopify.engineering/improving-the-developer-experience-with-ruby-lsp doesn't shed much light on this. I guess the main difference is about auto completion?

#434 had some nice info on it, but it wasn't merged, here it is rendered

The main difference is the philosophy behind typechecking. The Ruby LSP will not perform any elaborate typechecking and will instead expose an extension system that typecheckers can connect to for providing functionality. Solargraph's approach is to use YARD annotations for typechecking.

We will implement autocomplete, go to definition and other features. These are all unblock by the code indexer work #199.
