EDIT - this snippet only works in IVM. To support non-IVM, the rooms cache would need placed into Memory
So at the bottom of this post is an example script that uses the user/console API to create this functionality. It will inject the functionality into your running client whenever your global resets, or whenever you run the console command injectViewHistory();. It should never inject the functionality into your client more than once, even if the global resets. It will put an undefined into your console each time you change rooms. See this forum post for details on that functionality getting changed: https://screeps.com/forum/topic/2182/allow-third-party-software-to-not-spam-the-in-game-console
Note that this example script does not use the correct auth token end-point, so if you spam room changes rapidly, you could get rate-limited like @artch already stated. This call is very easy to change to a post with your auth token, but I did not use the auth token version in this prototype.
You must save the script below as a module named viewhistory. Then, in your main module you can then use it like this:
main.js
var viewhistory = require('viewhistory');
viewhistory.inject();
module.exports.loop = function() {
console.log(viewhistory.rooms());
}
viewhistory.js
let injected = false;
const _rooms = {};
const ROOM_LIMIT = 3;
global.injectViewHistory = function() {
injected = false;
inject();
}
function inject(){
if(!injected) {
injected = true;
var output = `<SPAN>Trying to inject View History code!</SPAN>
<SCRIPT>
if (typeof watching === "undefined") {
var watching = false;
let lastRoom = "sim";
function attach() {
if(!$('section.game').length) return setTimeout(attach,100);
let gameScope = angular.element($('body')).scope();
if (gameScope && !watching) {
watching = true;
gameScope.$watch('Loader.loadingCnt', (n) => {
if (n === 0) {
let roomScope = angular.element($('section.room')).scope();
if (roomScope) {
let Api = angular.element($('section.game')).injector().get('Api');
let room = roomScope.Room;
if (room) {
if (lastRoom !== room.roomName) {
lastRoom = room.roomName;
console.log("viewed " + room.roomName);
/* should be replaced with an auth token post to user/console instead of injected */
Api.post('user/console',{
expression: "viewedRoom('" + room.roomName + "');",
shard: room.shardName
});
}
}
}
}
});
}
}
$(function () {
setTimeout(attach);
});
}
</SCRIPT>`
console.log(output.replace(/(\r\n|\n|\r)\t+|(\r\n|\n|\r) +|(\r\n|\n|\r)/gm, ''));
}
}
function rooms() {
return Object.keys(_rooms);
}
global.viewedRoom = function(roomName) {
_rooms[roomName] = Game.time;
let keys = Object.keys(_rooms).length;
while (keys > ROOM_LIMIT) {
let oldest;
for (const roomName in _rooms) {
if (_rooms.hasOwnProperty(roomName)) {
if (!oldest || _rooms[roomName] < _rooms[oldest]) {
oldest = roomName;
}
}
}
keys--;
delete _rooms[oldest];
}
}
module.exports = {
inject,
rooms
};
