Rectangle & Ellipse Module in Ruby

[chackl]

Hello!

Today a was making some GUI in ruby and as a "Lession" i did a port of the old Rectangle & Ellipse Modules from Synthmaker V3 / FlowStone V2

As you see i also did properties for config

What is new is the Hatch-Brush.

If you have any ideas for updates/upgrades please write here

Base-Module - Free4Use in any Project.

For all Ruby nerds - please take a look how i did port all variables from te properties to the main module - maybe there is a better solution - if someone could do that


Best Regards

Hi chackl - nice stuff, bringing some of the new Ruby graphics options to a simple module.

Here's my version of the "options hasher". The @vals data is stored using the saveState/loadState methods, so there's no need for the 'input scanner, so there are far fewer events and triggers kicking about...

PS) Ruby instance variables (NOT local variables) can always be read, even before they are declared - returning nil if undefined. And there is a shorthand method for testing nils, ".nil?"
So...

Code: Select all

defined?(@vars) == nil

...can be simply written as...

Code: Select all

@vars.nil?

The "||=" that's used in my code is also very handy in situations like this. It's usually known as "OR-equals" - if the variable is undefined, nil or false, it gets assigned the right hand value, otherwise the old value is kept. Just take care if the variable is holding a boolean (true/false) value, though, as 'false' would be overwritten!

Thanks for the example i'll update it within the next version

And thanks for the little ruby lesson - I've just began to understand ruby and i'm now experimenting with custom objects and classes.

Thank you

Well a hatch allways needs 2 colors
So Hatch is an addition to solid/Linear/Radial.
