EVE Technology Lab

Hey pilots !

The first version of EVE-shopping has been released. This is a web application to help pilots in the process of replacing their ships.

You can find it here: eve-shopping.com

When this appliction was thought the main target was PVPers. I wanted something like eve-shopping to replace my own ships when i lose them, and i lose a lot

Anyway, EVE-shopping can be used by any pilot in game, doesnt matter if pvper or not.

The core of the application is based on a shopping list. Users, registered or not, can go and create a shopping list straight away in 3 steps:

1. Import your fits. This is the most important single step developed in eve-shopping and have try to add different ways for it, in-game and out of game.

2. Add items from market that may not be included in the fits.

3. Summary. Where you see all the items you added to the shopping list and can also tweak the final units. This final tweak is to adjust with items that you may have in your hangar coming from loots or previous shoppings.

Have try to make it easy and convenient to use. That is why the user doesnt need to login in the way to start using it.

When the user is loged in, it will have a list of personal fittings and shopping lists saved. So they can re-use its imported fits in new shopping list, or modify existing shopping lists at anytime without the need of saving the shopping list URL in his browser.

Normal shopping lists are always editable, but we find 3 kinds of shopping list in the application:

1. Shopping list. Editable, private, shopping lists. It can be modified at any time. In fact they can be seem like a blueptrint or template for advanced users.

2. Static shopping list. These shopping lists are public, anonymous and readonly. Static shopping lists are a picture of a shopping list in a given instant of time. Once a static shopping list is created it will never change, even if the original shopping list is modified. They are very useful to provide someone in a safe way, you just need to mail the link to anybody you want to have it. For example a friend that will do the shopping for you or an industrial that will buy or produce the items for you.

3. Group shopping lists. They are shopping lists where you dont add fittings or items from market, but, instead you import static shopping lists on it. A group shopping list will contains all the items that are conteined in all its related static shopping lists combined. This is ideal for a group of friends or small corp where someone is going to do the shopping to a trade hub and the friends ask to buy a few things for them. They just would need to create static shopping lists and provide to the one responsible of the shopping.

The application provides prices (based in average Jita in the last 24h, obtained from eve-central) and volume for every item and all combined. So you always know how much you spend and the size that things will take in your cargo bay.

I will continue mantaining the application and adding new functionality. Any feedback, pleassseeeee, is very welcomed

Well, i am sorry for this brick of text and all the mistakes i know i had in my english.

Have a look at it, i have try to make it easy to use, but i may have fail.

It is a simple application with only one functionality and one porpouse, to make shopping easier for the average player.

Fly safe!

Lovely. I'll be using this.

Thanks.

Some sort of checking the entries as 'bought' would be nice if you have long shopping lists.

Thanks for your efforts, I really appreciate it.

I just shopped about 100 assorted frigate fits using your app. Great stuff

This is really awesome. Speeds up the boring shopping alot. :) Thanks!

This is pretty awesome. =) Will be using this.

When i designed the units field, i did an estimation error, didnt espect such big ammounts and used int16 fields. Will replace them to int32. This will be fixed later today or tomorrow early, in v1.0.4.

Thanks



Absolutly! I have to improve this !

Right now eve-shopping only give a price estimation based only in Jita. This is nice for people like me, that only want to replace his lost ships and have an estimation of the price and the volume that it will take.

But for more advanced users i need to develop a way to customize the prices as you said. Manually and from other Sources.

I will start woking on this very soon. Need to find a balance in a way that pilots that want it simple, like this one writing , dont realise and also other more advanced ones have the chance to customize the pricing.



This is going to be a little more complicate. Not because of the effor need for it, that can be fixed with time. But because of eve-shopping philosophy.

In eve-shopping all lists are public, i am thinking to add a check to make it private.

Well, to be exact, all lists are public and anonymous. So if somebody has a link to your list, that means that he can see it, but dont know who it belongs too, unless you proviced the link to him and told him that it is you

Shopping list URL are based on GUIDs, so its complicate that someone can get a right link randomly. Anyway, even if someone gets it, it would never know who is the owner of the list and will not be able to modify it, so cant make much harm.

Also, this has to be completed, will be done this weekend. If someone that has the link access to a list and it is not the owner, then he can see the shopping list but not modify it. Unless the shopping list has no owner, as happens to shopping list created by non registered users.

This has a nice thing, it makes very easy and flexible how to share shopping lists. For example a corp could have a forum theread with shopping-lists that new users should buy in order to start flying in their fleets. Quite simple, not big user rights logic involved in it.

I think i should implement some sort of cloning functionality for shopping-list, in case that someone gives you a link and you want to clone it to your personal list

Also, eve-shopping is designed as a ONE functionality tool. Its meant to do only one thing, but grow and do it well and easy. This has some benefits.

For example, i would like to develop a public API. In that way other tools would be able to create shopping lists in eve-shopping. This would be useful for windows applications, so they would provide their users a way to open a browser in game with a shopping list and buy what they decided in the windows tool. Also could be useful for other web applicacions that do other things and later embed in their site a widget or iframe with shopping lists for their users. Still thinking about it and dont know if anybody would be interested to use it in his tool.

Anyway, i am in doubt about developing a brother site of eve-shopping, that uses the base of it and add more complex user, corp and market functionality. But, my god, no way i can think about that in a while. Maybe someone else could do it, i have no idea



Totally, we have to talk this weekend! By eve mail or chat

So much feedback in this thread!! I will add everything to eve-shopping feedback tool.

THANKS A LOT !!!

No problem! The thought behind the private shopping lists is that if individuals, corporations or even alliances start using this application and for example make a certain system their staging point, an extensive shopping list of items that are needed in that system could be used as a tool for the enemy to see exactly what the corp or alliance might be fighting with. Off course there is no way to really stop for example Goonswarm from getting that info either way since they have spies everywhere :) But this could make it at least a little bit harder.

In regards to that, would it be possible to make this application open source and publish it on for example Github? Because of the intelligence that someone can gather from a shopping it seems unlikely to me that most of the larger alliances would want to use this application on a large scale unless they can check the code on everything themselves and can install it on their own servers.

And i am sorry to say it, but i think eventually some sort of role system and permission system might still be needed. Ill give you an example: lets say i need 10 Sabre's + fittings at a random station in 0.0. someone from my corp sees that and decides to help me out and acquire the items in Jita and fly everything in a Jump Freighter to the station where they are needed. Only to find out that when he after a few hours arrives with the goods at the station that someone else already filled that order. In that particular case it would be very helpful if for example that person could lock down the shopping list and say that the order is being filled. That way no one looses any money by doing a double order of the same items.

What i am gonna suggest next is very complicated, and so i can totally understand if that won't be implimented:
A personal or corporate BPO, BPC, minerals, building components and other stuff needed for industry feature. For example, based on the shopping list someone else made you check with this feature if it is possible to manufacture the items at the quantity that the owner of the shopping list has asked. It is kind of like the website http://www.eve-cost.eu where you can add BPO's and BPC's to your own personal database, the Material Level and Production Level can be adjusted and based on the Material and Production level you can see how much of an particular item can be made and, if its enough to fill a shopping list. and what the total production profit or loss will be in comparison on the price the owner of the shopping list is willing to pay at max. You can see for example in a warehouse how much of the materials you have in stock in for example the staion, region or worldwide.

In fact, the point 2 of my previous post is the reason why i created the "static shopping list", to make the possibilitye to have a shopping list that can't be modified and could be part of a contract.

Hey!

Deployed the version v1.0.5 of EVE-shopping:

Group lists

- Added a readonly version of group lists. When a user has a link to a group list and is not the owner, he can see it, but not modify. Owner remains anonymous for the viewer.
- Added tweet buttom.
- Now is posible to attach to a group list a normal shopping lists and, also, static lists. Before was possible only statics.

Some bugs fixed.

Here is the change log: change log for v1.0.5

Thanks!

I found a few more bugs and things that could be improved upon, the bugs happen both when you are in the eve browser and outside the game:

When you add an item to a shopping list it happens quite often that a processing image shows up, but than nothing happens. The processing image stays there for a long time until you refresh the page. The item you added will appear than on the list.

Items cannot be removed from a list. I tried a couple of times to remove something in the market items tab, it will disappear there, but when you go to the summary tab, the items you removed appears again.

Add a way to remove an item from the summary tab.

There is currently no way to remove an static list from your shopping list. You have to delete an whole shopping list and start over again to stop a static list from showing up.

Once you open a list of statics lists on your My shopping lists page it stays open unless you refresh the page. Add an option to close the list of static lists by for example changing the show static lists link to s close static lists link if the static lists option is open.

It would be helpful if there was a comma to seperate the amounts of items or volume at large quantities. For example instead of 12934436.36 m3 it would be better readable and faster to understand if it was 12,935,436.36 m3. And the same same thing with isk values and number of items.

Add a way to automatically add x amounts of different items to a new list on the market items tab. Right now everything has to be added one by one, which when you want a lot of items on a list can be a tedious and long job. I was thinking of something similar like on these pages: http://eve-marketdata.com/copypaste.php Basically you can copy-paste something from your inventory in there and you see the right type of items and the right amounts once they have been processed.

Add a way to automatically for example add 10.000 units or 1.000.000 units of an item to a list. For example when you set the amount of items in a list you can add several buttons under the textbox where the number for amount of items goes and for example if you click on the 100.000 button 100.000 units will be added. And if you click 6 times on that button everytime 100.000 will be added, so a total of 600.000 units.
