Thor VS Gosu

Ruby has always been a great general-purpose scripting language and is often used to create command-line utilities. Many of these use the excellent Thor gem to parse command-line options, but there's no escaping one fact: command-line utilities just aren't interesting. Never have been, never will be.

All public methods in the generator will be called one after the other. Private methods will not be called but are available in your public methods like regular Ruby classes.

I will add that if you want to develop a CLI tool that gives you various commands that you can run, I would have a look at something like thor to keep it organised and documented. But this is completely unnecessary as a first step - you can simply create a Ruby file that does a thing you want and invoke it directly.

Not to be confused with generator functions (which you might be familiar with from Python or Javascript), Rails generators are custom Thor commands that focus on, well, generating things.

I wanted to provide a command-line interface for the user that was easy to use, and I also wanted to provide the flexibility with the options used to render the animation. After looking around online I found that Thor was a good tool to utilize. It allowed me to easily create a number of options that make this program much more versatile. An example below shows how a user can select which folder the source images are in, as well as what the background and foreground colors should be:

I've used Thor a lot, but it's kind of terrible. It uses a custom non-POSIX-compliant option parser (ex: method_option :list, type: :array -> --list one two three, where as the POSIX way is --list one,two,three or --item one -- item two --item three) and will not error on unknown options or exit with -1 when not enough args are given. If you want a better CLI library, checkout dry-rb, command_kit, or cmdparse.

And Thor might be worth looking at if you have complex scripts: https://github.com/erikhuda/thor

For the beginning, it will be a simple 2D game library (or glorified SDL wrapper :D), similar to Ruby libraries like https://www.ruby2d.com/ or https://www.libgosu.org/ , albeit with some additional functions typical to 2D games (like scenes, maps, entities, ...) available. This is something I'm still missing in Crystal (there are some bindings for C libraries and some early or abandoned approaches, but that's about it).

Sorry, I just realized that I only linked to Gosu's Linux instructions, but in their wiki there's also a page for Windows and another one for Mac OS.

I didn't use these frameworks but if you want to go with Ruby, I would recommend Gosu, which is more active than Ruby2D (they have a pretty active Discord server). Since it's a bit low-level, you could also use my gem MiniGL which builds on Gosu to make a lot of things easier, and I also actively maintain.

By the way, it's worth mentioning that there's a .deb for Debian-based distros that you can get for free on https://victords.itch.io/super-bombinhas. Also, if you're willing to do a bit more work, you should also be able to run it on Mac - you'd just have to install Ruby and the Gosu and MiniGL gems, then clone the game's repo and follow the Readme.

Hi! I've wanted to create an RPG inspired by the first Paper Mario games for a long time, but having to deal with 3D graphics was always a blocker for me... So I finally managed to create an isometric 3D "engine" using only 2D libraries (Gosu and MiniGL) and I'm happy with the results so far.

Gosu (Ruby)

I've not used it myself in about 5 years but it looks like they have a pretty good tutorial on getting started on their wiki https://github.com/gosu/gosu/wiki/Ruby-Tutorial

Neither, I use Gosu and my own little library, MiniGL.
