Zybez price retriever

[Boots]

Retrieves prices from zybez grand exchange.   Use the following format to retrieve prices, the price can be inputted with or without the "+" in bewteen each word

 PriceGrab priceGrab = PriceGrab.getInstance();
        priceGrab.getPrice("snape grass",3);

where the string parameter takes in the actual item name, and the integer parameter will determine if you want high value, low value, or average value. High = 3 , Average = 2, low = 1.

Nice, I wasn't going for a full zybez retriever, but yours looks good too.

Haha, I got bored. It relys on the Gson API and I don't know if that's provided by osbot.

 

Here's a nifty little utility I was able to make with it with little effort.

should extract the picture and maybe an auto fill feature would make it nice

I'm really bad at swing, so I'm not sure how to make this look decent.

 

 

For the auto complete, that'd be a nifty feature, but all this does is grab what you put in the box and appends it to the end of the url. I dont think I can make it auto complete without a list of item names of some sort.

[Toastedmeat]

Here you go a list of item names and ID's

Thanks, I added suggestions similar to how irc works. "dragon sc + tab" return dragon scimitar

[Haridos]

Gson has something called a FieldNamingStrategy, you can use this to rename fields from the zybez api to your own api

[GoldenGates]

Very nice and helpful, the other snippet I used seemed to return a 404 error for me, but that was weeks ago.

 

@@Kenneh, very nice "script like" thing you've got there. ^.^

[Smoking Guams]

Nice hope it gets implemented

 

[While]

static PriceGrab getInstance

I hate static

[Boots]

static PriceGrab getInstance

I hate static

Its the singleton pattern used to avoid multiple object creations
