So, been messing around with userscript lately, in tampermonkey. And hence had a few problems saving and loading with GM_setValue and GM_getValue. There are a couple of scrips out there to sort this for you, but none that i was able to get to work. So I’ve wrapped my own version up, which also compresses via LZstring. (google it).<\/p>\n\n\n\n
d.save(“float”, 12.34);
d.load(“float”);<\/p>\n\n\n\n\n\n\n\n
For my purpose i found it most reliable to include whole libraries inside an anonymous function together with any code. This seem to help som scope issues I had, at a potential cost of performance (none that I have noticed tho). I’ve also included waitForKeyElement, cause it is nice to have at hand.<\/p>\n\n\n\n
In principle the functions just wrap anything into an object (which you dont really need to do, but wth), stringifies, saves MD5, compresses, saves. And vice versa.<\/p>\n\n\n\n
It does not work as expected with any data. Seems safe for sring, int, float, bool, undefined, null, objects and arrays. Does not work for NaN or functions as far as i can tell. Also not sure about “new Date()” objects and the like.<\/p>\n\n\n\n
However for all intents and purposes it seem reliable enough.<\/p>\n\n\n\n
The whole ting is included in a file further down, with some examples. Here are the main methods themselves.<\/p>\n\n\n
