/* 
StripSearch.js: strips Wikipedia search results down to bare pagenames. It provides 
the "SR detail" menu item to hide/show the search results' details and the sister 
project results. Search results are preprocessed to remove all redirected entries 
and members of matching categories, so that they do not show up at all.

Version 1.4 -- operational.

This script uses the core control structure and subroutines from
[[User:The Transhumanist/OutlineViewAnnotationToggler.js]]:
https://en.wikipedia.org/w/index.php?title=User:The_Transhumanist/OutlineViewAnnotationToggler.js&oldid=807301505

Brief comments are provided within the sourcecode below. For extensive explanatory 
notes on what the source code does and how it works, see the Script's workshop on 
the talk page. (Not ready yet.)

// ============== Set up ==============

// Start off with a bodyguard function to reserve the aliases mw and $
( function ( mw, $ ) {

    // we can now rely on mw and $ within the safety of our “bodyguard” function, to mean 
    // "mediawiki" and "jQuery", respectively (they follow the closing curly bracket - see the end of the script)

	// ============== Load dependencies ============== 
	mw.loader.using( ['mediawiki.util'], function () {
	
    // ============== ready() event listener/handler ==============
    // below is jQuery short-hand for $(document).ready(function() { ... });
    // it makes the rest of the script wait until the page's DOM is loaded and ready
    $(function() {
        
		// ============== activation filters ==============
        // Run this script only if " - Search results - Wikipedia" is in the page title
		if (document.title.indexOf(" - Search results - Wikipedia") != -1) {

			// End of set up
			
       	    // =================== Prep work =====================
				
			// Variable declarations, etc., go here

   	        var SRDetailSwitch; 

           	// ================== Core program =================== 

			// Strip out redirected entries, and entries from matching categories
			$("li").has(".searchalttitle").remove();

            // get the value of our status variable from memory
            // (this tells us what mode to start in)
            // "SR" stands for "search results"
            var SRDetailStatus = localStorage.getItem('SRDetailStatus');

			// Core control construct:				
            // run the function corresponding to the current status
            if ( SRDetailStatus === "hide" ) {
                SRDetailHide();
            } else {
                SRDetailShow();
            }
        }

        // ======================== Subroutines ===========================
        // Functions (aka subroutines) are activated only when they are called.
        // Below are the functions called in the core control structure of the program above.
        // They are placed at the end of the program, so that the script's flow 
        // is easier to follow.

        // ============ Function to hide search results' detail ==============
        function SRDetailHide() {
            // store status so it persists across page loads
            localStorage.setItem("SRDetailStatus", "hide");

            // Hide the search results' details (show elements by class per http://api.jquery.com/hide)

           	//$( ".searchresult" ).hide();
           	//$( ".mw-search-result-data" ).hide();

			// Replace the search results by hiding the original results and use .after to insert a modified version of those results
			// Development note: somehow assign an id of "Stripped" to the contents of the .after chain below, so that it can be accessed later
			$('ul.mw-search-results').hide().after(
				$('<div id="Stripped"></div>').append(
					$('ul.mw-search-results')
