  • setup-nu@v1 supports Nu v0.60.0 ~ 0.63.0;

Examples

Basic

In most cases you just need to specify the version of Nushell to be used in your workflow. For example the following installs the v0.80 version of Nushell. Then you can set the command you want to run in the following steps, and don't forget to set shell: nu {0} to make the commands be executed by nu:

- uses: hustcer/setup-nu@v3.7
  with:
    version: "0.80" # Don't use 0.80 here, as it was a float number and will be convert to 0.8, you can use v0.80/0.80.0 or '0.80'
- run: print $'Nu version info:(char nl)'; version
  shell: nu {0}
- name: Default shell will be `nu`
  shell: nu {0}
  run: |
    print $'Nu path:(which nu)(char nl)'
    def greeting [name: string] {
        print $'Hello ($name)'
    }
    greeting hustcer

Used as Default Shell

Of cause, You can also set the default shell to nu by setting the defaults.run.shell config:

name: basic

on: push
defaults:
  run:
    shell: nu {0}

jobs:
  basic-usage:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4.0.0
      - uses: hustcer/setup-nu@main
        with:
          version: "*"
      - run: version; print $"(char nl)Dir contents:(char nl)"; ls ((which nu).path.0 | path dirname)
      - run: |
          print $'Current env:(char nl)'
          print $env
      - name: You can run bash commands, too
        run: pwd && ls -la
        shell: bash

Use Nu Modules

To use modules in Nu, please refer to the following examples:

  1. Use Nu modules in nu -c
- name: Setup nu
  uses: hustcer/setup-nu@v3.7
  with:
    version: 0.86
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
- name: Use Your Nu Modules
  shell: nu {0}
  run: |
    nu -c "use nu/module.nu *; print (get-env 'ABC-XYZ' 'DEFAULT-ABC-XYZ')"

You have to wrap the nu code in nu -c "", and the nu version should be equal to or above 0.69.

  1. Use modules from absolute path
- name: Setup nu
  uses: hustcer/setup-nu@v3.7
  with:
    version: 0.86
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
- name: Use Your Nu Modules by Absolute Path
  shell: nu {0}
  run: |
    use ${{ github.workspace }}/nu/module.nu *
    print 'Use module from: ${{ github.workspace }}/nu/module.nu'
    print (get-env 'ABC-XYZ' 'DEFAULT-ABC-XYZ-ABSOLUTE-PATH')

Again, the nu version should be equal to or above 0.69.

  1. Copy your modules to one of the default $env.NU_LIB_DIRS
- name: Setup nu@latest
  uses: hustcer/setup-nu@v3.7
  with:
    version: 0.86
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
- name: Prepare Nu Modules
  shell: nu {0}
  run: |
    let LIB_DIR = [$nu.default-config-dir 'scripts'] | path join
    if not ($LIB_DIR | path exists) { mkdir $LIB_DIR }
    cp -r nu/* $LIB_DIR
- name: Use Your Nu Modules
  shell: nu {0}
  run: |
    use module.nu *
    print (get-env 'ABC-XYZ' 'DEFAULT-ABC-XYZ')

To make it work please make sure that the nu version should be equal to or above 0.85.

They are not perfect yet, but they do work. BTW: Please tell me if you found a better way and PRs are always welcomed.

Use Nu Nightly Version

Nushell is currently in active development, if you want to use the latest features it's also available by set the version to nightly, just as below:

- uses: hustcer/setup-nu@v3.7
  with:
    version: nightly # Will download and setup the latest nightly version of Nushell
- run: print $'Nu version info:(char nl)'; version
  shell: nu {0}
- name: Default shell will be `nu`
  shell: nu {0}
  run: |
    print $'Nu path:(which nu)(char nl)'
    def greeting [name: string] {
        print $'Hello ($name)'
    }
    greeting hustcer

Warning Use Nushell nightly version with caution: The nu binary may change every other day and this may break your workflow. Only the latest nightly version will be downloaded and setup, and the version must be nightly.

Others

Or, check the following examples:

  1. run-test.yaml
  2. run-matrix.yaml
  3. Advanced example: How Nushell Make a Release? Workflow, Script

If you want to use the latest version of nushell you can specify this by set check-latest to true(it's the same as version: '*', but more readable). For example the following installs the latest version:

- uses: hustcer/setup-nu@v3.7
  with:
    check-latest: true
- run: print $'Nu version info:(char nl)'; version

Note: Before Nushell reaches 1.0, each version may change a lot, it is recommend that you use a specified version instead.

In rare circumstances you might get rate limiting errors, this is caused by the workflow has to make requests to GitHub API in order to list available releases. If this happens you can set the GITHUB_TOKEN environment variable.

- uses: hustcer/setup-nu@v3.7
  with:
    version: "0.80"
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Inputs

Name Required Description Type Default
version no A valid NPM-style semver specification, such as 0.86.0, etc. and nightly. string *
check-latest no Set to true if you want to use the latest version bool false
enable-plugins no Set to true if you want to register the bundled plugins, Nu v0.69 and above is required bool false

The semver specification is passed directly to NPM's semver package. This GitHub Action will install the latest matching release.
