@pbroom/color-kit/driverColor input

resolveColorInputDraftValue

Parses a typed draft with parseColorInputExpression, then wraps or clamps the result into options.range (see normalizeColorInputValue). Returns null when the draft does not parse, so the input can keep or revert its value.

Example

TypeScript
import { resolveColorInputDraftValue } from '@pbroom/color-kit/driver';

const alpha = { currentValue: 0.3, range: [0, 1] as [number, number] };
resolveColorInputDraftValue('50%', alpha); // → 0.5
resolveColorInputDraftValue('1.5', alpha); // → 1
resolveColorInputDraftValue('abc', alpha); // → null
resolveColorInputDraftValue('+0.1', { ...alpha, allowExpressions: true }); // → 0.4

const hue = { currentValue: 0, range: [0, 360] as [number, number] };
resolveColorInputDraftValue('370deg', { ...hue, wrap: true }); // → 10
