Project mention: JetBrains' unremovable AI assistant meets irresistible outcry | news.ycombinator.com | 2024-02-03I suggest looking for blog posts about this, you're gunnuh wanna pick out a plugin manager and stuff. It's kind of like a package manager for neovim. You can install everything manually but usually you manually install a plugin manager and it gives you commands to manage the rest of your plugins.
These two plugins are the bare minimum in my view.
https://github.com/nvim-treesitter/nvim-treesitter
Treesitter gives you much better syntax highlighting based on a parser for a given language.
https://github.com/neovim/nvim-lspconfig
This plugin helps you connect to a given language LSP quickly with sensible defaults. You more or less pick your language from here and copy paste a snippet, and then install the relevant LSP:
https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...
For Python you'll want pylsp. For JavaScript it will depend on what frontend framework you're using, I probably can't help you there.
pylsp itself takes some plugins and you'll probably want them. https://github.com/python-lsp/python-lsp-server
Best of luck! Happy hacking.
Templ for the templating engine. Although Go already have a decent templating engine, I'm planning to use Templ because it's more powerful and flexible. I really like this library and I'm planning to use it in my future projects.

Project mention: Pylyzer – A fast static code analyzer and language server for Python | news.ycombinator.com | 2024-04-11
In neovim I would recommend setting shellcheck with null.ls or using the bash language server: https://github.com/bash-lsp/bash-language-server
both work really well
Project mention: Open source versus Microsoft: The new rebellion begins | news.ycombinator.com | 2024-04-15One of the things that comes to mind here is the fact that the default Python extension for VS Code is, perhaps surprisingly to many, not open source. https://github.com/microsoft/pylance-release
While it's possible to fork VS Code, it is not possible to fork VS Code and provide a seamless onramp towards a Python editing experience that is fully open source, because users are used to the nuances of the closed-source Pylance experience in VS Code proper. You could use the minified/compiled Pylance plugin in your fork, but you'd have no way to expand its capabilities to new hooks your fork provides. Microsoft's development process would always be able to move faster than a fork, because it could coordinate VS Code internal API development with its internal Pylance team, and could become incompatible with forks at any time.
It's worth re-reading the quote from J Allard in https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguis... with this modern example in mind.
(Also worth mentioning https://github.com/detachhead/basedpyright?tab=readme-ov-fil... which is a heroic effort to derisk this, but it's an uphill battle for sure!)
I'm going to use intelephense to show the minimal configuration needed to setup a language server in Neovim.
Project mention: Kotlin is a much better language than Java even with all the new stuff Java has added. | /r/Kotlin | 2023-12-11There's a community-made one, but of course as much effort as has been put into it it's not as featureful as JetBrains's own stuff.
No. Not even close. But it's getting better.
There are currently two worth mentioning:
ElixirLSP: https://github.com/elixir-lsp/elixir-ls
Elixir tools: https://www.elixir-tools.dev/
ElixirLSP is the older project, and has been around for a while. It does a lot, but has had sporadic issues over the years. Things like the debugger are a dog to get working, and the server itself will occasionally run into issues where it just doesn't want to work. It's always sort of focused on a subset of language server features, so don't expect much in the way of inline corrections. But it's got the essentials, formatting, basic linting, type hinting, on demand documentation, and primitive reference navigation
Elixir tools is a new up and comer, written by Mitchell Hanberg. It's aiming to be a more complete lsp, and has plugins in its "ecosystem" for most editors. Features have been arriving rapidly, starting with things like inline corrections and far more reliable linting, and recently growing autocomplete. One of the main selling points is the elixir-tools backend is a self contained binary, so it can mostly work independent of system Elixir/Erlang version, which was a frequent tripping point for ElixirLSP
Personally I use both at the same time, but plan to move to tools only when it's got all the features I need
I'm still waiting for clangd support, e.g. [0] before trying modules.
- [0] https://github.com/clangd/clangd/issues/1293
Usually another program is used to lint/format code. Basic way is to just run them as a shell command or in another terminal and reload the file, but you can also hook it up to lsp. For example Javascript/Typescript projects use eslint and prettier. Runing `npx prettier` will format the files according to default rules. This is fine for every once in a while or a pre-commit hook. I think you are looking to have it integrated in nvim. Most formatters don't have a language server so you can connect them to nvim lsp with a general language server like: https://github.com/mattn/efm-langserver
Project mention: LSP with pylsp: it work-ish but autocompletion and hover randomly work. | /r/vim | 2023-06-05I am reading here but still... it seems all OK. It is weird that it was working with ALE with the current setup. Anyway, I noticed that every once in a while I get this error when I change buffer.
