Quickstart

Installing nur

If you are familiar with rust/cargo you may want to install nur using cargo:

> cargo install nur

See installation for more details on how to install nur.

Add a nurfile to your project

You should add a file called nurfile to your project root folder. Add this file to version control as well, to share your tasks with your team. You can also extend the available tasks locally by adding a separate nurfile.local file to your project.

Adding some tasks

nur tasks are defined by using sub commands to nur in your nurfile, following the normal nu syntax using def. A simple task could look like this:

def "nur hello" [] {
    print "Hello world"
}

You can then use nur hello to execute this task. Tasks may call external command like npm ci or poetry install or anything else you like. Tasks can also call other tasks, see the working with nur section for more details.

All tasks will be executed in the directory the nurfile was found in. If you place a nurfile in your project root (git root) you will be able to call tasks from anywhere inside the project. This is useful to always have a reproducible base setup for all your tasks.

About task names

It is recommended to define and use a naming schema for your tasks. This could for example be something like:

• nur install: Setup the project, install all dependencies
• nur update: Update the project, update all dependencies
• nur test: Run all tests
• nur lint: Lint the project
• nur run: Run the project, for web project start the dev server
• etc.

See best practices for more details on how to structure your tasks.

Switching to nur from any other task runner

If you are already using a task runner like just or b5 you should read switching to nur to get an overview on how to switch to nur.
