Chocolatey Utilities

Purpose

The purpose of choco-dependencies is:

• To show the dependencies of one or more of the Chocolatey packages that are installed on your system or...
• To show which packages depend on one or more of the Chocolatey packages that are installed on your system.

Usage

If choco-dependencies is started without any package names supplied, it will show the dependencies or dependants of all packages. You may select one or more packages as follows:

choco-dependencies packagenamelist

where:

packagenamelist := packagename [, packagenamelist]

To show dependants, run the utility as follows:

choco-dependencies -Reverse [packagenamelist]

How it works

This utility goes through the following stages:

1. Checks whether it is running on Windows and exits if it isn't. Chocolatey is Windows-only so it makes no sense to allow running on other platforms.
2. Uses the environment variable ChocolateyInstall to find the Chocolatey lib directory.
3. Here it scans all .nuspec files in all subdirectories for dependencies and stores them as arraylists in a hashtable. The -Reverse option determines how the dependencies are stored:
   • If not set, the module being scanned is used as index in the hashtable and the dependency is stored in the arraylist it indexes.
   • If set, the dependency is used as index and the module being scanned is stored in the arraylist it indexes.
4. And finally it shows the dependencies for the modules that you have chosen.

Notes

Output is text-only. This may change to be some kind of object (to make it more "powershell'y") but so far I have not found out what that should be.
