litphoria

So it turns out this is fully implementable using HTML5 local storage and incredibly hacky DOM manipulation. This is functional as either a bookmarklet or directly pasted into the debugger.

WA, kill me now.

litpho_type_buffer.js

//Litphoria typing buffer saver (litpho_type_buffer.js)
//Hacky and framework-averse but functional and relatively safe

//NB: interferes with typing indicator, sue me

var litphoria_type_buffer_textarea = null; //the editbox DOM element itself to manipulate
var litphoria_type_buffer_id = null; //the id of the chat or roleplay
var litphoria_type_buffer_type = null; //whether this is a chat or a roleplay
var litphoria_type_buffer_storage = null; //the name of the HTML5 storage key value where this RP's buffer exists

var litpho_type_buffer_poll_rate = 1000; //Polling interval in ms: probably an event-driven way of doing this but while we're being hackery let's go the whole hog

//Sets all the variables we need above to get up and running
function litphoria_type_buffer_init(){

    //For the love of god if there is a better way of populating these replace these lines
    var split_url = window.location.href.split("/");
    if(!isNaN(parseInt(split_url[4])&&(split_url[3]=="roleplay" || split_url[3]=="chat")))
    { //Half-arsed validation
        litphoria_type_buffer_id = split_url[4];
        litphoria_type_buffer_type = split_url[3];
        litphoria_type_buffer_init_textarea();
        return true;}
    else {
        alert("Litphoria type buffer extension failed to initialize: bad url (not a roleplay?)");
        return false;} //Nope out, do not pass go, do not collect $200
}

//Awful hack the first: try to work out if the page has loaded without knowing the framework state
//Fortunately, this script literally only cares about the state of the editbox
//So we can basically run a loop until we find it
//WA I am so sorry
function litphoria_type_buffer_init_textarea(){var textarea = null;
    try {
    textarea = document.getElementsByTagName("li-input")[0].childNodes[1]; } //MONSTROUSITY
    catch (err) //Lazy as shit but whatever
    {setTimeout(litphoria_type_buffer_init_textarea,litpho_type_buffer_poll_rate);}
    if(textarea != null) {litphoria_type_buffer_textarea = textarea; litphoria_type_buffer_runner();}

    //This is so incredibly tacked on
    document.getElementsByTagName("li-typing-indicator")[0].childNodes[0].innerHTML += " [Buffer Saved] ";}
}
