fish-shop/install-plugin

A GitHub action for installing fish shell plugins.

---

Prerequisites

This action requires fish shell. You can install it using the fish-shop/install-fish-shell action.

Usage

Add a suitable uses step to your GitHub workflow and specify the plugin manager and plugin(s) to be installed by providing values for the plugin-manager and plugins inputs respectively:

jobs:
  install-plugin:
    runs-on: ubuntu-latest
    steps:
      - name: Install Pond plugin with Fisher
        uses: fish-shop/install-plugin@v2
        with:
          plugin-manager: fisher
          plugins: marcransome/pond

Tip

The plugins input supports multiple space-separated plugin names/URLs. The exact format is dependent upon the plugin manager being used and you should refer to the plugin manager's documentation for additional information (see Supported plugin managers).

Note

For additional safety, the inputs plugin-manager and plugins are handled internally using intermediary environment variables and escaped to mitigate the risk of script injections.

The plugin manager will be installed only if not already present. If your workflow job contains multiple install-plugin actions that use the same plugin manager then only the first action will install the plugin manager.

If you wish to install a plugin manager in isolation, without installing any plugins at the same time, consider using the fish-shop/install-plugin-manager action instead.

Supported plugin managers

The following table lists the supported plugin managers and the corresponding plugin-manager input value to use in your workflow:

Plugin manager	plugin-manager value
Fisher	fisher
Oh My Fish	oh-my-fish 1
plug.fish	plug.fish2

Action versions

Use one of the following patterns when specifying the version reference for this action in your workflow (i.e. the {ref} value in uses: fish-shop/install-plugin@{ref}):

Pattern	Example	Description
vX	v2	the latest v2.* release including non-breaking changes and bug fixes
vX.Y	v2.1	the latest v2.1.* release including bug fixes
vX.Y.Z	v2.1.0	the v2.1.0 release only

Tip

The recommended pattern is vX (e.g. v2). This will ensure that the version of the action used in your workflow includes the latest non-breaking changes and bug fixes, and guarantees compatibility with previous versions of that major release number.

Using a main branch reference in your workflow is not recommended as this branch may include breaking changes intended for the next major release.
