Installation

Nightly build​

Ki is under heavy development, so we recommend downloading the most recent nightly build from github.

VS Code Extension​

Ki is also available as a Visual Studio Code extension, at https://marketplace.visualstudio.com/items?itemName=ki-editor.ki-editor-vscode.

Build from source with Nix​

This is the most reliable installation method as all required dependencies, including system dependencies, will be included automatically.

  1. Ensure that Nix: the package manager is installed.
  2. Clone the project:
git clone https://github.com/ki-editor/ki-editor.git
  1. Run installation:
nix develop --command just install

Build from source without Nix​

  1. Ensure the Rust toolchain is installed using rustup.rs.
  2. Use Rust 1.89.0:
rustup default 1.89.0
  1. Clone the project:
git clone https://github.com/ki-editor/ki-editor.git
  1. Run installation:
cd ki-editor
cargo install --locked --path .
  1. The ki binary should be installed.

Use nix flake 1​

1. Install ki package​

  • with nix profile:
nix profile add github:ki-editor/ki-editor
  • or as part of nix configuration, e.g.:
{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    ki-editor.url = "github:ki-editor/ki-editor";
  };

  outputs = { nixpkgs, ki-editor, ... }: {
    nixosConfigurations."«hostname»" = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
         { environment.systemPackages = [ ki-editor.packages.x86_64-linux.default ] }
         ./configuration.nix
      ];
    };
  };
}

2. Build tree-sitter grammars​

This step is optional as most of the Tree-sitter grammars are already linked at build time.

ki @ grammar fetch && ki @ grammar build

Footnotes​

  1. This flake also provides a basic development environment for Ki Editor which can be enabled by nix develop command. ↩
