On-demand icon definitions

[suasgn]

Currently Blockstudio 7 bundle a massive SVG icon definitions (https://github.com/inline0/blockstudio/tree/main/includes/icons).

It will be better if the definitions are served on-demand so the Blockstudio source code/built file are more lean.

We have built a similar workaround for the on-demand SVG icon library with Omni Icon plugin (https://github.com/nabasa-dev/omni-icon/), you may want to check our implementation, or maybe collaborate so we can make a bridge to connect them easily.

This is example of how our picowind theme integrate the picowind plugin: https://github.com/livecanvas-team/picowind/blob/main/src/Supports/OmniIcon.php

<?php

/**
 * Get an icon using Omni Icon plugin if available.
 *
 * @param string $iconName Icon name in format "prefix:icon-name" (e.g., "mdi:home", "local:my-logo", "omni:windpress")
 * @param array $attributes Optional HTML attributes to add to the SVG element
 * @return null|string the SVG HTML if exists, or null if couldn't found or plugin not active
 */
function get_icon(string $iconName, array $attributes = [])
{
    // Validate icon name format
    if (! str_contains($iconName, ':')) {
        return null;
    }

    try {
        $iconService = \OmniIcon\Plugin::get_instance()->container()->get(\OmniIcon\Services\IconService::class);

        // Convert boolean and numeric attributes to string representation
        foreach ($attributes as $key => $value) {
            if (is_bool($value)) {
                $attributes[$key] = $value ? 'true' : 'false';
            } elseif (is_int($value) || is_float($value)) {
                $attributes[$key] = (string) $value;
            }
        }

        // Use Omni Icon plugin's IconService to render the icon as HTML string
        return $iconService->get_icon($iconName, $attributes);
    } catch (\Exception $e) {
        // Log errors in debug mode
        if (defined('WP_DEBUG') && WP_DEBUG) {
            error_log("OmniIcon error: {$e->getMessage()}");
        }
        return null;
    }
}
