language-server-protocol VS vim-lsp

But these are typically filling the usecases of productivity applications, not ‘engines’.

Microsoft Word doesn’t run its grammar checker as an external service and shunt JSON over a localhost socket to get spelling and style suggestions.

Photoshop doesn’t install a background service to host filters.

The closest pattern I can think of is the ‘language servers’ model used by IDEs to handle autosuggest - see https://microsoft.github.io/language-server-protocol/ - but the point of that is to enable many to many interop - multiple languages supporting multiple IDEs. Is that the expected usecase for local language assistants and image generators?

If you tried writing code like the one above, your Rust LSP should already be telling you that what you're doing is unacceptable:

A language server is an external program that follows the Language Server Protocol. The LSP specification defines what type of messages a language server can receive, and also how it should respond. The idea here is that any tool that follows the LSP specification can communicate with a language server.

> There's a strange dance of IDEs coming and going, with their idiosyncracies and partial plugins.

The Language Server Protocol [1] is the best thing to happen to text editors. Any editor that speaks it gets IDE features. Now if only they'd adopt the Debug Adapter Protocol [2]...

The Gno Language Server (gnols) is an implementation of the Language Server Protocol (LSP) for the Gno programming language. It is similar to the equivalent “gopls” project for Go, as they can be plugged into your code editor through extensions and allow you to access handy features, such as autocompletion, formatting, and compile-time warnings/errors. Gnols makes writing code simpler, working with several editors to suit your preferences. To try it out, visit the CONTRIBUTING.md file, which contains instructions to get you started. Our current documentation targets Vim, Neovim, and SublimeText, but can likely be used with any editor that supports LSP. Feel free to contribute to improving Gnols and adding more features. It’s well-written, and simple to dive into the code and add more capabilities.

Honestly, you should read some of the docs [0] if these are the sorts of questions you're asking.

hey HN. this is a Language Server[0] designed specifically for Postgres. A language server adds features to IDEs (VSCode, NeoVim, etc) - features like auto-complete, go-to-definition, or documentation on hover, etc.

there have been previous some attempts at adding Postgres support to code editors. usually these attempts implement a generic SQL parser and then offer various "flavours" of SQL.

This attempt is different because it uses the actual Postgres parser to do the heavy-lifting. This is done via libg_query, an excellent C library for accessing the PostgreSQL parser outside of the server. We feel this is a better approach because it gives developers 100% confidence in the parser, and it allows us to keep up with the rapid development of Postgres.

this is still in early development, and mostly useful for testers/collaborators. the majority of work is still ahead, but we've verified that the approach works. we're making it public now so that we can develop it in the open with input from the community.

a lot of the credit belongs to pganalyze[1] for their work on libg_query, and to psteinroe (https://github.com/psteinroe) who the creator and maintainer of the LSP.

The nxls is a language server based on the Language Server Protocol (LSP) and acts as the “brain” of Nx Console. It analyzes your Nx workspace and provides information on it, including code completion and more.

LSP stands for "Language Server Protocol", which defines how a language server and an editor (client) can communicate to provide code navigation, completion, etc. (source). Traditional IDE's would have something similar to this baked-in already, but proprietary to their software/language; whereas LSP is an open standard, so anything could implement it.

Has anybody managed or got an idea how to make SonarLint Language Server work with e.g. vim-lsp?

You need to configure a language server. For C++ it's a bit tricky, so good luck with Go. There are other plugins that provide semantic highlighting using LSP, for example https://github.com/prabirshrestha/vim-lsp (I didn't try it, but it seems good).

ALE can use LSP as well. And if you are using vim-lsp, you can use the same instance of server for both with vim-lsp-ale bridge plugin.

I feel the same way. Not a one-liner but the smallest config LSP plugin I've found is vim-lsp. It works in both Vim and Neovim.

The only major feature that Neovim still has is a built in LSP client. But I find the built in Neovim LSP client is unusably buggy, you're much better off using any of the other LSP plugins. What I use is vim-lsp, but I've tried all of the major lsp client, they are all significantly better than the built in Neovim LSP.

As for install/configuration, all you need is the latest Vim, the plugins I mentioned, and that bit in your vimrc. You can do a bit better than that if you copy the entire config with mappings from the vim-lsp GitHub page.

I have a problem with Deoplete and Vim-LSP completion (Python's Pylsp and Jedi-Language-Server). The suggestion is much less, and it also misses a lot of opportunities to suggest compared to Deoplete-Jedi, which literally defeats the former by a large margin. Is there a setting to make this duo works like deoplete with deoplete-jedi?

- add the [prabirshrestha/vim-lsp](https://github.com/prabirshrestha/vim-lsp) plugin and config to your `.vimrc` (note: `pylsp` is *not* necessary).
