Removing cobra library dependency

[gkerdal]

Here is a new topic for discussing how to remove cobra library dependency.

Context : cobra is a graphical library used in jajuk to show wikipedia web content. The library doesn't seem to be maintained, it has been fixed by jajuk team for the 1.10 Jajuk version to fix a bug.

Bertrand suggested me the link [1] below to replace the Wikipedia view.

I managed to make it work on a prototype version of Jajuk with Oracle JDK 8 installed (Ubuntu). The content of wikipedia is correctly displayed, even images, it may require a bit more ressources than cobra library but it's just my opinion.

Before going further testing, let's discuss this JavaFx solution.

JavaFx seems only integrated in Oracle JVM since Java 7 (u 6). On previous version it is a separate component, but that's not a big drawback since Jajuk now requires Java 7.

I found on the [2] link that JavaFX si not yet integrated in Open jdk 1.8. So using JavaFX may force Jajuk users to install proprietary Oracle Jvm, not sure it's compatible with jajuk's principles. What do you think ?

Thanks Gwen for your searches. IMO, it's a NO-GO if we need an Oracle JDK (and anyway, I suppose I wouldn't work on OSX). So you found a new java lib ;-) ?

Hi Bertrand, I agree too, that's too restrictive. I'll have a look at CSSBox library. If you ever heard about anything else, let me know, I can have a look.

Hi Gwen, no, I'm not aware of any other solution. Just make sure that any new lib is well supported, is cross-platform (linux/windows/OSX) : 100% pure java like cobra if possible.

Being already packaged into Debian would be a big plus. Cheers, Bertrand

I may have a solution : from jre 8, the Swing JTextPane seems to be enough for our needs. I tested it and it looks acceptable to me (and the user can click on the rocket to open the wikipedia page in a regular browser) :

What do you think ? want me to push my changes so you can have a look ?

Thanks for pushing, I'll have a look tomorrow.

Please check out the feature/html branch. It contains a very naive POC of the solution.

Hi Bertrand,

It's a correct solution, I see no issue so I think you can push it to develop branch.

Cheers,

Gwen.

All right, I'll have a look at it. My current implementation is very basic.

Thanks, Bertrand
