Forge Auto-Updater

[Qriist]

Hello there, I've created a simple updater that will look for the latest snapshot on snapshots.cardforge and update your copy of Forge if something new comes along.

It will simply launch Forge if you (a) have the latest snapshot or (b) cannot connect to the internet. Though, the very first time you run it, it will go through the whole process as it doesn't have a clue as to what version you actually have.

Once it finds the need to update it will download, test file integrity, and extract all the files to the folder the updater resides. Thusly, set it in your forge folder and create a shortcut to Forge Updater.ahk/exe.

It does have one dependecy, 7za.exe, which it will attempt to automatically download from my personal storage (static links, yay!). If you are leery about this you can download 7za.exe yourself from the 7-zip homepage (it's in the portable package) and place it in the same location as the updater.

Updating Forge is kind of a pain because I never know when there is a new release. Now I don't need to.

This was written in AHK and the source code is provided, as is the compiled version.
Enjoy!

Source Code: (minus the actual links it connects to, due to spam filters. It is provided in the zip'd copy.)

EDIT: Minor change to the package cleanup. Consolidated a few lines.

Good idea!

It works perfectly on my machine. I think it would be a great feature in the base game too.

Thank you for the kind words.
