What language for an IDE

• tauri

  469 76,929 9.8 Rust

  Build smaller, faster, and more secure desktop applications with a web frontend.

  

VSCode is built with Electron. Another web-ish alternative would be Tauri.

• xi-editor

  42 19,805 2.6 Rust

  A modern editor with a backend written in Rust.

  

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• egui

  203 19,596 9.7 Rust

  egui: an easy-to-use immediate mode GUI in Rust that runs on both web and native

Also, I’d replace C and C++ options with Rust. For C++ there are GUI projects like imgui which are also available for Rust, and there is a similar cool project called egui for Rust. There is a website dedicated for Rust GUI: areweguiyet.com.

• ripgrep

  348 44,747 9.3 Rust

  ripgrep recursively searches directories for a regex pattern while respecting your gitignore

An example of a performance-critical feature is the project-wide text search, which is ripgrep (Rust). Microsoft publishes that library as an npm package / Node native addon.

• vscode-ripgrep

  4 102 6.2 JavaScript

  For consuming the ripgrep binary from microsoft/ripgrep-prebuilt in a Node project

• drracket

  4 441 7.7 Racket

  DrRacket, IDE for Racket

  

To be fair, I'm not exactly sure which parts of emacs are written in C, but all extensions which make it more than an editor (i.e. an IDE) are interpreted lisp. Still, I'm not convinced. Another example, DrRacket, the IDE for Racket is written entirely in Racket, and that's plenty fast as far as I can tell*. It's a bit slow to start up, but that's all Racket programs.
