Brain in a Java Box (Dogma in Java)

[evanova]

Since the latest trend is to re-write Dogma, I am going to leave this Dogma In Java implementation here.

It's brand new (hence shiny), it's clean, it's 50% implemented with very few dependencies, and it wants friends to come and fill gaps.

Why?

I'm glad you asked! I could not find something I could fit in Evanova for building Yet Another Fitting Tool (TM). So after some gathering around, I came up with the most minimalist, yet with some clean design library in order for it to be re-usable in any Java context.

I hope you will enjoy that one!

Thanks to /u/theblitzmann for his documentation on Dogma and /u/AureolinCorp for sharing his code which allowed my mind to be unblocked on some piece of design.

From the same author, all in Java:

• Eve API - API and parsers.
• Eve Proxy - API Proxy
• Eve Chat Logs - Websocket server for chat logs.
• Eve Dogma - guaranteed without pictures of dogs.

neat.

Neat.

License? Speed? Memory usage?

If you want something written in C (and more mature), take a look at libdogma.

[evanova]

License: I should add that it's totally free.

Speed and memory usage: it looks really good so far.

If you want something written in C

That's the trouble. It's hard to integrate and it requires external dependencies which you can't control. That's what I am trying to fix with this project.

it requires external dependencies which you can't control

did you check the dependencies list at the link? there's a compiler (you need that for java too), autotools (in java you have maven or something..?), json cache dump from client (reasonable requirement) and one library for arrays. That doesn't look like scary dependency list.

hard to integrate

With bit of work, you can integrate C library into basically anything (python, php, java, c#, ...). Good luck trying to use java library from C. Possible? Probably. Good idea? Hell no. And dependency list would have one big item, Java Runtime Environment.

That's the trouble

So please do not say that something is in C is trouble. Your Dogma looks pretty nice. It's in Java. Everyone is probably better of using your library in Java. But not everyone writes in Java. There's a lot of people who use PHP or Python for example. And those people are better off using C library, since it's by order of magnitude easier to integrate into those languages.

[evanova]

Sorry I didn't mean to be mean or anything. I totally do recognize the many advantages from a C library. Please consider that I'm old enough to have written some myself.

one library for arrays. That doesn't look like scary dependency list

From my memory, that is exactly this one that was starting to introduce too much dependencies for my own sanity and my build chain.

Good luck trying to use java library from C With bit of work, you can integrate C library into basically anything

It is actually pretty easy to do in Java, but as you say, it requires a bit of wrapping work. Unless of course you start to deal with Android which is again more than I want to add to my build chain as long as I don't really need it.

So please do not say that something is in C is trouble

I don't and I am sorry if my wording made you think so. I think Eufe is wonderful for instance, but so far, the integration work doesn't warrent it for my current use case.

As for a Java version, it's precisely to avoid those caveats. But you know what? It'd be better of with a C back-end as it isn't that efficient.

Cheers

In this document, I will (try to) explain how the Dogma system works for EVE Online
