Rust Extension for the Nova Text Editor

This project brings Rust Language support to the Nova text editor (macOS only). It is written in TypeScript for static typing, but transpiled to run in the macOS JavaScript environment using Nova's API for extensions. This extension provides Rust developers with syntax highlighting, assistance from the Rust Analyzer language server, error checking, and automatic formatting.

Users

Nova users can install this extension from Nova's Extension Library, available within the app. More information for users is available in the extension details.

Developers

Requirements

To help develop this extension, you'll need the Nova app, of course.

To build the scripts for this extension, you will need Node installed (and the npm package manager that comes with it).

Setting Up the Dev Environment

Start by running the update_server.sh script to download the Rust Analyzer binary, then rename it manually:

$ cd Rust.novaextension/bin/
$ ./update_server.sh
$ mv rust-analyzer-new rust-analyzer
$ cd ../..

This is done for users automatically, but in Nova's Developer Mode for extensions any file change triggers a reload of the extension, and thus you'd get stuck in an endless loop. In Dev Mode, I have the extension skip attempts to update Rust Analyzer.

Now you can install dependencies and build the scripts:

$ npm install
$ npm run build

After the scripts are transpiled, you can test the extension in Nova by selecting Extensions -> Activate Project as Extension. Open a Rust project to see it in action. You can monitor logs and errors by selecting Extensions -> Show Extension Console from the menus in the Rust project.
