Theme refine search tags

[lysytsya459]

Hello,
I wanted to emulate e926 "+ -" links that show next to relevant tags when you are searching tags, I was able to do it inside my own custom theme in the tag_list.theme.php file like so:

// top of file make sure to include these
use MicroHTML\HTMLElement;

use function MicroHTML\{A, BR, rawHTML, emptyHTML, joinHTML, TABLE, COLGROUP, COL, THEAD, TH, TR, TD, SPAN};
// ...
public function display_refine_block(Page $page, array $tag_infos, array $search): void
{
        global $config;

        $main_html = emptyHTML(
            $this->get_refine_tag_list_html(
                $tag_infos,
                $config->get_string(TagListConfig::POPULAR_SORT),
                $search,
            ),
            rawHTML(" "),
            BR(),
            A(["class" => "more", "href" => make_link("tags")], "Full List")
        );

        $page->add_block(new Block("Refine Search", $main_html, "left", 60));
}
private function get_refine_tag_list_html(array $tag_infos, string $sort, array $search): HTMLElement
{
        if ($sort == TagListConfig::SORT_ALPHABETICAL) {
            asort($tag_infos);
        }

        $table = $this->get_tag_list_preamble();
        foreach ($tag_infos as $row) {
            $table->appendChild($this->build_refine_tag_row($row, $search));
        }
        return $table;
}
public function build_refine_tag_row(array $row, array $search): HTMLElement
{
        // ...
        $search_query = url_escape(Tag::implode($search));

        $add_tag = url_escape($tag);
        $add_tag_link = "/post/list/" . $add_tag . " " . $search_query . "/1";
        $tr->appendChild(TD(
                ["class" => "tag_add_link_cell"],
                A(
                        [
                                "class" => "tag_add_link",
                                "href" => $add_tag_link,
                        ], "+" )));
                
        $remove_tag_link = "/post/list/-" . $add_tag . " " . $search_query . "/1";
        $tr->appendChild(TD(
                ["class" => "tag_remove_link_cell"],
                        A(
                        [
                                "class" => "tag_remove_link",
                                "href" => $remove_tag_link,
                        ], "-" )));
               
        //...
}

So the code for refining searches with + and - links has been there for years, but ~10 years ago somebody redid the html generation and skipped calling it 🤦

#1361 activates it again

That's great, thanks for the fix
