hi,
i was wondering, if you can take a string and parse it into code that processing executes.

so that you can take a string like this one
String a = "println("this works");"
and processing executes the println method

i am thinking about this, because i am working on a proejct that is getting pretty large, and i would like to take some segments of the code and put them in a txt file, so i can keep my processnig sketch a bit cleaner.

Alternately you could

A. Bite the bullet and migrate to Eclipse, providing a cleaner development environment

B. Take a portion of the "stable logically connected" Tabs and create a library, thus making the sketch "cleaner"

i tried to switch over to eclipse allready, but i found it to be a little bit complicated, so i got discouraged. maybe i should give it another try though... the library idea is nice too, but somewhat limited in effect, since i can only do this with few tabs (yes, i use tabs)

OK, keep in mind this is not the solution at your specific problem (somehow, you can make a library out of part of your code...). But Java has scripting capability, and out of the box it can load and execute JavaScript code... There are lot of other languages, like Lua, that it can run this way. On in other ways. With interpreted languages, that's a way to execute code out of some text file...

My suggestion isn't as stupid as it seems... Lot of games have a core in C or C++ (or Java), to manage graphics and other time consuming tasks, and delegate part of their logic, mainly AI and level description, to Lua scripts (or other languages, but Lua, simple yet powerful, is popular in the game industry).
