Maybe we should change enigma to java, then you can use execute_string() as much as you like

Please Speak English 
I'm sorry, but I'm not very experienced with Enigma development.

I want to be able to read and write to xml language

Why don't we implement JavaDoc then?

what about wxWidget?

Not easily no. It would be faster to embed QT in ENIGMA.

Is that sarcasm or suggestion?

Is there anyway I can display Enigma inside a GUI component such as those in QT?

How does one write a plugin API in general? I haven't much experience in writing (anything) actually. I've only started slowly learning Java for the last 2 years. Should I write this "API" by having other developers write their custom classes and then I'll use a classLoader to load their classes on run time, like Minecraft Forge (you'll know if you write minecraft mods)?
How was the enigma plugin for lgm written?

Will code refactoring ever be available?   

Thank you, IsmAvatar, you have told me exactly what I need to hear. I admit that I have been pushing the project too fast, my trial and error parser is now practically unreadable, I'll have to rewrite it soon.

I wanted to use this project in school so badly that I have been working day and night on it, trying to add cool features without really thinking of its long term usability. I will now slow down and document my code better. However, I'm still going to implement images, sounds and videos into these notes soon! I would be really happy if you guys could download this IDE and try it (not know, its not complete) and give me feed back 

Lonewolf, I am using java Swing to make the IDE, Swing seems to be a good and easy option. What kind of game engine are you working on and may I see it?

I am currently working on a small but very radical IDE for my custom language. What I'm trying to do is to create an object oriented language for note taking in classrooms (or note taking in general). For example, in Geography class, I can make an object called Sphere and then create sub objects called Lithosphere, biosphere...
I already have the object language syntax marking done, along with code suggestion, I can also reference these objects in normal typing. Oh and since this is only a scripting language, space between variables are permitted
Here is a simple screenshot:



While the development of this IDE is going smoothly, I still haven't got to the hard part yet (implementing images, sounds and camera for taking notes ...)
If you look close enough, you'll see small white rectangles, that would be my attempt to give it a moving background, like the live wallpaper on Androids. Its based on a dynamic background library that i wrote which is basically a small particle system. I wanted to style my IDE with themes such as falling snow when its Christmas, flying bats on Halloween... I have a lot more themes too (aquarium, sky with birds and clouds, ...). I try to make the background dark and move slowly so as to not distract the user.
What I am asking is, when you guys make an IDE, what were the hardest things that you have encountered, and how did you solve them?

Here are some links if you wanna take a look, I use Eclipse.

I'm glad that most of everyone here likes Eclipse 

I used the lgm source from the svn website: http://sourceforge.net/projects/lateralgm/
if it is outdated, then where may i find the source of the latest lgm?

After a few hours studying LGM's wild source code (I really wish there are more comments and javaDocs    ) I decided to make a small feature to see how I understood LGM's basic components. I've added 2 force directed graphs, one to show an object 's events and actions, the other to show all resources in a project (objects, backgrounds, ...) and also objects and their events.
I added a "View" menu in the menubar for project visuallization, and a "Visualize" button in the obj frame.
Drag right mouse to zoom.
Download it here : https://www.dropbox.com/s/3hp184w14at89uf/Crazy%20LGM.jar?dl=0
I have used the substance library for the cool-looking GUI : https://github.com/Insubstantial/insubstantial/releases/tag/insubstantial_7.3
and the visualization toolkit called prefuse: http://sourceforge.net/projects/prefuse/
Please know that I don't really understand most of LGM's code because my experiences with java isn't enough. However, I am quite proficient with writing Android apps and am planning to port LGM to Android, perhaps you guys can help! 

I have recently found a swing look and feel called Substance, and it looks really good on enigma, could someone such as IsmAvatar go change the skin on lgm please? 
you can find the project here: https://github.com/Insubstantial/insubstantial
you also need the trident library: https://kenai.com/projects/trident/pages/Home
