I've been wanting to check out lsp-mode under Emacs for a while now. LSP stands for Language Protocol Service. The idea is that you have a standard interface between your editor and some language server. If you program in multiple languages and each has an LSP server you end up, in theory, with a simpler configuration and a consistent interface.
This certainly sounds more appealing than how we did it in the old days where you have some ad hoc configuraiton for each language you work in. At times I'm working or dabbling in a whole bunch of languages. At times, my Emacs configuration has had separate sections for each of the following languages:
- Emacs Lisp
- C and C++
This can get messy.
So, LSP sounds cool but when I've tried to get it going in the past I've always had troubles. This time, I tried a different approach. I decided to declare .emacs.d bankruptcy. I cleared out my .emacs.d directory and started fresh. Not really fresh - I copied over The critical parts of my configuration to start with - Swiper, email and org config and a few other things. Then I got lsp-mode working for Python and C++. Now I'm going to migrate over more of my old configuration as I discover I want, miss, or need things. We'll see how it goes.
The new configuration can be found here: https://github.com/zamansky/dot-emacs
