neovim-ui VS language-server-protocol

mjlbach/neovim-ui

I understand the frustration (making neovim more cohesive is definitely a goal). It sounds like coc provides the UI you are used to, so there's no harm in sticking with that!

Many of our users explicitly don't want automatically called functions that would slow down the editor (autocommands that map signature requests to the language server, for example), so by nature neovim's core implementation is extremely conservative.

One thing I would like to do, is make the automatic pop-ups for signature easier to implement with our current handler, which means a plugin like signature-x could use our upcoming lsp.config option to configure it's borders (https://github.com/neovim/neovim/pull/14681), and match the rest of the UI.

I also have another project I was working on before the 0.5 stabilization phase (https://github.com/mjlbach/neovim-ui). The goal with this is to have composable/overridable UI elements built into core (which we would use for our internal lsp functions), that can be used (or overridden) by UI plugins.

In summary, I think the likelihood of autocompletion (and generally auto-anything) being built-into core is very small, but providing the APIs in neovim core to make snippets - autocompletion - automated UI elements easier for plugin authors is a high priority.

Yep, I started working on this awhile ago https://github.com/mjlbach/neovim-ui but put it on hold for 0.5 stabilization.

I am working on this, but it will probably have to wait until after the 0.5 release (I don't know when this will be). This is part of the larger UI effort in neovim-ui which is currently glorified vaporware. As far as I know, TJ, Smolck, and I are the only ones who have expressed interest in fixing this.

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.
