Feature Request - 2024-06-01 - String Validator

[azurepolarbear]

Description

We want to add a StringValidator class. The only methods right now will be confirming that something is a valid RGB hex string (#RRGGBB) or a valid RGBA hex string (#RRGGBBAA).

The logic for these checks already exist in the unit tests (/src/test/shared/color.ts: checkForValidHexColorString(hex: string).

Tasks

• create class
• implement valid RGB hex string check
• test valid RGB hex string check
• implement valid RGBA hex string check
• test valid RGBA hex string check
