Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ollama is now available on Windows in preview
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?

The Mechanics of mutable and immutable references in Rust
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 guide on Neovim's LSP client
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.

The IDEs we had 30 years ago and we lost
> 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 More You Gno: Gno.land Monthly Updates - 6
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.

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

Show HN: Postgres Language Server
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.

Nx Console gets Lit
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.

How to configure vim like an IDE
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.

LSP could have been better
Recently I stumbled upon this issue:
https://github.com/joaotavora/eglot/discussions/1127
I don't know enough about emacs and LSP to see the full picture, but it seems that both eglot's and corfu's maintainers, assumably very competent programmers, can't find a solution for this.
I only skimmed the thread. My understanding is that LSP dumps a long list of completion candidates at once and they can't decide a cache strategy that works well with existing code...?

Spurious errors with Eglot / pylsp
It could be. There are unfixed issues with eglot and corfu, and sadly not a lot of willingness to investigate.
-
Using Quarto with Emacs
Eglot errors when I add new Python code blocks. The error disappears when I reconnect the language server, but the same happens again when I add a new code block. My "workaround" now is that before I start working on the .qmd file, I just add a bunch of Python code blocks (for which I also have a function) and then reconnect the language server again. This way I can start working for a while until I need to add more code blocks again.

Looking for help in improving Typescript Eglot, Corfu, Orderless performance
This discussion has helped with some performance issues: https://github.com/joaotavora/eglot/discussions/993.

Typescript highlighting in emacs incomplete (compared to VSCode) even after using treesitter?
I guess eglot doesn't support it yet: https://github.com/joaotavora/eglot/pull/839

joaotavora/breadcrumb: Emacs headerline indication of where you are in a large project
This is not by pure chance, João is the developer of the Eglot LSP client and the breadcrumbs from LSP-mode had been requested as a feature, but as far as I remember João thought rightfully that this could be an independent package, see https://github.com/joaotavora/eglot/discussions/988

Returning emacs user - what packages are common now?
A substantial section of the community is using corfu instead of company, but I wouldn't say company is out of date by any means. In emacs 29 eglot will be a built in, which might act as a replacement for lsp-mode depending on what functionality you need.
-
Eglot upgrade strategy
I am currently running emacs 29 (built from emacs-29 branch) which – according to https://github.com/joaotavora/eglot – should contain the latest eglot.

916 Days of Emacs
Yep. You can use flymake or flycheck for that in combination with eglot or lsp-mode.

Eglot, eldoc and golang
(I have reported this (that is, ElDoc missing docs for callable things at point, when Eglot is enabled) as an issue recently: First on GitHub-discussions https://github.com/joaotavora/eglot/discussions/1200, then on Debbugs https://debbugs.gnu.org/cgi/bugreport.cgi?bug=62687. But the threads are very long, so I don't recommend reading them.)
