@keybindy/core/dist/utils/expandAliases.js

A lightweight and framework-agnostic keyboard shortcut manager for web apps. Define, register, and handle keybindings with ease.

const keyAliases = {
    ctrl: ['ctrl (left)', 'ctrl (right)'],
    shift: ['shift (left)', 'shift (right)'],
    alt: ['alt (left)', 'alt (right)'],
    meta: ['meta (left)', 'meta (right)', 'cmd'],
};
function expandAliases(binding) {
    const expanded = [[]];
    for (const key of binding) {
        const normalized = key.toLowerCase();
        const variants = keyAliases[normalized] ?? [normalized];
        const newExpanded = [];
        for (const existing of expanded) {
            for (const variant of variants) {
                newExpanded.push([...existing, variant]);
            }
        }
        expanded.splice(0, expanded.length, ...newExpanded);
    }
    return expanded;
}

export { expandAliases };
