Package Manifest Editor

Package Manifest Editor is a utility to edit package manifests through code.

Installation

1. The package is available on the openupm registry. You can install it via openupm-cli.

openupm add net.tnrd.packagemanifesteditor

2. Installing through a Unity Package created by the Package Installer Creator from Needle

Usage

Before you can do anything you'll have to open a manifest for editing like so

private void Foo()
{
    ManifestEditor editor = ManifestEditor.OpenById("Package Folder Name");
}

I personally put my packages in folders with the reverse domain name notation so I would use something along the lines of ManifestEditor.OpenById("tld.domain.packagename");

Supported attributes

This package follows Unity's manifest definition which can be found here: https://docs.unity3d.com/Manual/upm-manifestPkg.html

The odd one out are is the dependencies attribute. This one can only be read by using the Dependencies property on the ManifestEditor.

To add a dependency one can use the AddDependency method like so

private void Foo()
{
    ManifestEditor editor = ManifestEditor.OpenById("tld.domain.packagename");
    editor.AddDependency("tld.domain.packagedependency", "1.0.0");
}

The second parameter requires a version number according to the Semantic Versioning spec using Artees' SemVer.

Removing a dependency is done using the RemoveDependency method like so

private void Foo()
{
    ManifestEditor editor = ManifestEditor.OpenById("tld.domain.packagename");
    editor.RemoveDependency("tld.domain.packagedependency");
}

Saving

Once you're done with your changes you can save the manifest file. It will overwrite the existing one on disk.

private void Foo()
{
    ManifestEditor editor = ManifestEditor.OpenById("tld.domain.packagename");
    // Do some changes
    editor.Save();
}

Undoing your changes

If you want to undo your changes you can simply reload the manifest from disk like so

private void Foo()
{
    ManifestEditor editor = ManifestEditor.OpenById("tld.domain.packagename");
    // Some changes applied that you want to undo
    editor.Reload();
}

Support

Package Manifest Editor is a small and open-source utility that I hope helps other people. It is by no means necessary but if you feel generous you can support me by donating.
