Nim Language Server Protocol
Language Server Protocol implementation for Nim
This is a Language Server Protocol implementation in Nim, for Nim. It is based on nimsuggest, which means that every editor that supports LSP will now have the same quality of suggestions that has previously only been available in supported editors. This will compile and install it in the nimble binary directory, which if you have set up nimble correctly it should be in your path. When compiling and using nimlsp it needs to have Nim's sources available in order to work. With Nim installed through choosenim these should already be on your system and nimlsp should be able to find and use them automatically. However, if you have installed nimlsp in a different way you might run into issues where it can't find certain files during compilation/running. To fix this you need to grab a copy of Nim sources and then point nimlsp at them on compile-time by using -d:explicitSourcePath=PATH, where PATH is where you have your Nim sources. -

Verible
Verible is a suite of SystemVerilog developer tools
The Verible project's main mission is to parse SystemVerilog (IEEE 1800-2017) (as standardized in the SV-LRM) for a wide variety of applications, including developer tools. It was born out of a need to parse un-preprocessed source files, which is suitable for single-file applications like style-linting and formatting. In doing so, it can be adapted to parse preprocessed source files, which is what real compilers and toolchains require. The spirit of the project is that no-one should ever have to develop a SystemVerilog parser for their own application, because developing a standard-compliant parser is an enormous task due to the syntactic complexity of the language. Verible's parser is also regularly tested against an ever-growing suite of (tool-independent) language compliance tests. A lesser (but notable) objective is that the language-agnostic components of Verible be usable for rapidly developing language support tools for other languages. -

LTEX LS
LTeX Language Server: LSP language server for LanguageTool
LTEX LS (LTEX Language Server) implements a language server according to the Language Server Protocol (LSP) and provides grammar and spelling errors in markup documents (LATEX, Markdown, etc.). The documents are checked with LanguageTool. Typically, you start the language server (either locally or remotely), you send the language server your LATEX or Markdown document, and it will respond with a list of the grammar and spelling errors in it. To use LTEX LS in this way, you have to use a language client (usually an editor or an extension of the editor) that communicates with LTEX LS according to the LSP. However, it is also possible to supply LTEX LS paths to files and directories to be checked as command-line arguments. In this mode, LTEX LS will print the results to standard output, and no language client is necessary. -

Python LSP Server
Fork of the python-language-server project
Fork of the python-language-server project, maintained by the Spyder IDE team and the community. A Python 3.7+ implementation of the Language Server Protocol. The base language server requires Jedi to provide Completions, Definitions, Hover, References, Signature Help, and Symbols. Like all language servers, the configuration can be passed from the client that talks to this server (i.e. your editor/IDE or another tool that has the same purpose). The details of how this is done depend on the editor or plugin that you are using to communicate with python-lsp-server. The configuration options are available at that level are documented in CONFIGURATION.md. Overall configuration is computed first from user configuration (in home directory), overridden by configuration passed in by the language client, and then overridden by configuration discovered in the workspace. -

JupyterLab LSP
Coding assistance for JupyterLab (code navigation + hover suggestions
Hover over any piece of code; if an underline appears, you can press Ctrl to get a tooltip with function/class signature, module documentation or any other piece of information that the language server provides. Critical errors have red underline, warnings are orange, etc. Hover over the underlined code to see a more detailed message. Use the context menu entry, or Alt + 🖱️ to jump to definitions/references (you can change it to Ctrl/⌘ in settings); use Alt + o to jump back. Place your cursor on a variable, function, etc and all the usages will be highlighted. When a kernel is available the suggestions from the kernel (such as keys of a dict and columns of a DataFrame) are merged with the suggestions from the Language Server (in notebook). If the kernel is too slow to respond promptly only the Language Server suggestions will be shown (default threshold: 0.6s). You can configure the completer to not attempt to fetch the kernel completions if the kernel is busy. -

LunarVim
An IDE layer for Neovim with sane defaults
LunarVim is an opinionated, extensible, and fast IDE layer for Neovim >= 0.5.0. LunarVim takes advantage of the latest Neovim features such as Treesitter and Language Server Protocol support. LunarVim ships with a sane default config for you to build on top of. Features include autocompletion, integrated terminal, file explorer, fuzzy finder, LSP, linting, formatting and debugging. Just because LunarVim has an opinion doesn't mean you need to share it. Every built-in plugin can be toggled on or off in the config.lua file. This is the place to add your own plugins, keymaps, autocommands, leader bindings and all other custom settings. LunarVim lazyloads plugins wherever possible to maximize speed. Disabled plugins also will not decrease speed due to the plugin list being compiled with only the active plugins. This strategy allows LunarVim to not have to choose between features and speed. -

cquery
C/C++ language server supporting multi-million line code base
C/C++ language server supporting multi-million line code base, powered by libclang. Emacs, Vim, VSCode, and others with language server protocol support. Cross-references, completion, diagnostics, semantic highlighting, and more. cquery is a highly-scalable, low-latency language server for C/C++/Objective-C. It is tested and designed for large codebases like Chromium. cquery provides accurate and fast semantic analysis without interrupting workflow. cquery implements almost the entire language server protocol and provides some extra features to boot. cquery is able to respond to queries quickly because it caches a huge amount of information. When a request comes in, cquery just looks it up in the cache without running many computations. As a result, there's a large memory overhead. For example, a full index of Chrome will take about 10gb of memory. If you exclude v8, webkit, and third_party, it goes down to about 6.5gb. -
24
csharp-ls
Roslyn-based LSP language server for C#
This is a hacky Roslyn-based LSP server for C#, as an alternative to omnisharp-roslyn. csharp-ls requires .NET 7 SDK to be installed. However, it has been reported to work with projects using older versions of dotnet SDK, including .NET Core 3, .NET Framework 4.8 and possibly older ones too as it uses the standard Roslyn/MSBuild libs that Visual Studio & omnisharp does. csharp-ls implements the standard LSP protocol to interact with your editor. However there are some features that need a non-standard implementation and this is where editor-specific plugins can be helpful. Supports automatic installation, go-to-metatada (can view code from nuget/compiled dlls) and some additional features. -
25
Elixir Language Server
A frontend-independent IDE "smartness" server for Elixir
Implementing features such as auto-complete or go-to-definition for a programming language is not trivial. Traditionally, this work had to be repeated for each development tool and it required a mix of expertise in both the targeted programming language and the programming language internally used by the development tool of choice. The Elixir Language Server (ElixirLS) provides a server that runs in the background, providing IDEs, editors, and other tools with information about Elixir Mix projects. It adheres to the LSP, a standard for frontend-independent IDE support. Debugger integration is accomplished through a similar VS Code Debug Protocol. These pages contain all the information needed to configure your favorite text editor or IDE and to work with the ElixirLS. You will also find instructions on how to configure the server to recognize the structure of your projects and to troubleshoot your installation when things do not work as expected.
