Lapce

Lightning-fast And Powerful Code Editor


Lapce (IPA: /læps/) is written in pure Rust with a UI in Druid (which is also written in Rust). It is designed with Rope Science from the Xi-Editor which makes for lightning-fast computation, and leverages OpenGL for rendering. More information about the features of Lapce can be found on the main website and user documentation can be found on GitBook.

Features

  • Built-in LSP (Language Server Protocol) support to give you intelligent code features such as: completion, diagnostics and code actions
  • Modal editing support as first class citizen (Vim-like, and toggleable)
  • Built-in remote development support inspired by VSCode Remote Development. Enjoy the benefits of a "local" experience, and seamlessly gain the full power of a remote system.
  • Plugins can be written in programming languages that can compile to the WASI format (C, Rust, AssemblyScript)
  • Built-in terminal, so you can execute commands in your workspace, without leaving Lapce.

Building from source

It is easy to build Lapce from source on a GNU/Linux distribution. Cargo handles the build process, all you need to do, is ensure the correct dependencies are installed.

  1. Install the Rust compiler and Cargo using rustup.rs. If you already have the toolchain, ensure you are using version 1.62 or higher.

  2. Install dependencies for your operating system:

Ubuntu

sudo apt install cmake pkg-config libfontconfig-dev libgtk-3-dev

Fedora

sudo dnf install gcc-c++ perl-FindBin perl-File-Compare gtk3-devel
  1. Clone this repository (this command will clone to your home directory):
git clone https://github.com/lapce/lapce.git ~/lapce
  1. cd into the repository, and run the build command with the release flag
cd ~/lapce
cargo build --release

If you use a different distribution, and are having trouble finding appropriate dependencies, let us know in an issue!

Once Lapce is compiled, the executable will be available in target/release/lapce.
