Question 1

How do I install Shoes 4 on Windows?

Accepted Answer

Install JRuby and JDK 7 or 8, then run 'jruby -S gem install shoes --pre' from the command line. Ensure your system meets the SWT requirements, and avoid JDK 9 as it's incompatible.

Question 2

Shoes 4 vs Tk for Ruby GUI development?

Accepted Answer

Shoes 4 offers a more Ruby-like DSL and native widgets, but is in preview with JRuby dependency. Tk is mature and works with standard Ruby, but has an outdated interface and less intuitive syntax.

Question 3

Can Shoes 4 run on Raspberry Pi?

Accepted Answer

No, Shoes 4 lacks ARM support because it relies on SWT, which does not support ARM architectures like the Raspberry Pi, as noted in the README's system requirements.

Question 4

How to package a Shoes app as a standalone executable?

Accepted Answer

Use 'bin/shoes package --mac' or '--jar' followed by your script path, but be cautious as it includes all files in the directory. Configure an app.yaml file for more control over packaging options.

Question 5

Is Shoes 4 stable enough for a school project?

Accepted Answer

Yes, for learning and prototypes, but since it's in preview with known issues, expect occasional bugs. For critical assignments, consider more established tools or test thoroughly.

Question 6

What happens if I use JDK 9 with Shoes 4?

Accepted Answer

It won't work; the README explicitly states JDK 9 is incompatible with JRuby and thus Shoes 4. You must use JDK 7 or 8 to avoid runtime errors.
