Language Servers: How Do They Work?

In this stream, we'll talk about language servers, a kind of development tool that can provide any text editor or IDE with rich development support for a specific programming language or platform.
We'll discuss the underlying protocol, how language server programs operate, and how they connect to programs like Emacs to enhance your development experience.

Thanks a lot Ashraz!

[@user-oj1ng4pv4i]

Ohh.. I am the one who requested this topic.. and iImissed it..

[@johnadams1444]

When I worked at Microsoft several years ago I also use emacs without anyone caring. All that mattered was that code was being written. I wasn't even the only person on my team using it (for most teams, we did get re-orged around a bunch). Lots of people is visual studio or vscode, but sublime text and vim were also well represented.

This is a mysterious topic for me, so I'm glad you are covering it. I really want to understand how to setup and run these language servers under Guix.

[@mauricio0guaruja]

you could use jq shell command to improve json readability, you could M-| with jq '.' , I think that should be enough

[@mauricio0guaruja]

jq is used to query and process json on shell. Kinda like awk, but specific for json
