If you're using 3.2's apilevel (thus not using the new image/resource system, yes, the script (code) will be compatible.

Hello!
After wasting a bit of time with fractals I finished the second v2.0 alpha release today I also tried to use the "callStack" and "locals" information of the registered error handler but unfortunately those are not available for code loaded with the loadstring function, so this feature will not be possible to implement.  Anyways, here's what's new:


New features:
- the whole color-set can be customized now (menu => Style => Customize) (no custom syntax coloring yet!)
- added menu to the console application: choose which logs you want to get displayed! (The small squares in the upper right corner are indicators: black=print; red=errors; blue=status)
- now use of platform.registerErrorHandler ==> no crash possible anymore (on apilevel>1.0)
- use of custom error handler is still possible
- safe use of 2DEditors: they get removed as soon as you stop the script


Improvements/Changes:
- various fixes
- slightly optimized and improved syntax colouring
- now all dialogues are centered
- switched back to rendering only ascii characters because of performance; they still work but in the editor they are representated by their UTF-8 code
- added dialogue for stopping the user script


I also noticed that I have fallbacks for all apilevel 2.0 features, so I can continue the support for OS3.1 for now

3.1! Great! I found a bug: when I launch the script and I modify it by removing a character, the application makes an error:
991: attempt to index field '?' (a nil value)

LDStudios: Those libraries are in the guide in the editor.

Hi, sorry for this late update, but I didn't have much time lately...
Anyways here's the 3. alpha release of v2.0!


New Features/Improvements:
- change fontsize with "shift" & "+" and "shift" & "-"
- global environment now resets for each new build
- ctrl+M selects the current line and moves the cursor to its end
- rudimentary "find" function (menu=>"View"=>"Find")
- 90% faster and more accurate syntax colouring algorithm  (image code is defenitely no problem anymore!  )
- EE key now inserts a "#"
- improved file name format (longer names and less bugs)
- button rebindings now also works for dialogue inputs


Bugfixes:
- fixed a crash after undoing (still many bugs to fix with undoing...)


I also started working on a gui engine for better dialogues and easier and faster development of the guis for customnizations and other advanced functions! 

So, here is the 4. alpha release of v2.0!


New Features & Improvements:
- implemented gui engine ==> better dialogues
- fully functional "find" function
  - option to search only whole word
  - option to search from cursor or from script start
  - enable/disable case sensibility
- autocompletion: press the return(↵)-key to open the autocompletion menu (customizability planned)
- color of strings, comments, keywords and lua standardFunctions is now customizable (proper syntax marking options are planned)
- replaced the old "Load" menu by a new filemanager
  - function to rename files
  - saved files can now be seen by OS 3.1!
- polished look of user script page


Fixes:
- moved menu initialization into on.activate ==> menu shows up on all OS again (sorry, forgot to fix it earlier )
- removal of "carriage return" characters of pasted texts


PS: I wrote the gui engine from scratch and didn't do thaat much testing, so some features might be a bit buggy! Feel free to report all bugs you find! 

I missed a lot while on vacation, this is looking amazing!
I can't wait to try it, great work as always!

I have a few suggestions:
-Ability to enable a specific key to restart script while on the page that runs it (any key or no key) because its annoying to do ctrl+left, escape, menu, enter, enter every time you want to restart it.
-Custom Libraries, with Adriweb's Better Lua API as a built in library. Also the ability to add other libraries of your own.
-Menu Items that are toggle based should have a checkmark next to them when turned on (checkmark character is in the character lib.. somewhere) EDIT: for things like font, write the current font next to it.
-Still waiting for that Standard Lib API guide 

EDIT:

Okay, so I tried it out, and I have a few more suggestions/bug reports:
-Use of cursor.set() for selecting items in a dialog box, and for buttons
-Ability to  click the X in the top right of the customize box
-Clicking outside of a dialog box is the equivalent of pressing escape
-The application that runs the script didn't work for me until I clicked on the page, after the first time it worked fine
-In the customization menu, draw a square with the current color of the item, next to the name of the item so you can tell what it is currently set to
-Ability to mark check boxes with cursor as well as buttons
-Customization of syntax separate from customization of other stuff
-Ability to save custom themes
-Ability to customize dialog box colors

Also, how did you use ctrl+M to select the line?

2nd EDIT: I just wrote a lot of stuff ^ I understand if you don't want to do any of it, or if its just too much. Just a few of my thoughts to improve. Can't wait for the next update! 

Very nice
(I summed it up on tiplanet, btw)

Nice! I like that updates still get translated to ti-planet for the french community! 

Also, it crashed (line 2327 : attempt to index field '?' a nil value) when I tried to copy a part of the code I selected.

Thanks for the report, but I was not able to recreate the bug and I have no idea what could have caused it... But I made that part a bit safer to prevent a crash

Why don't you just enable the errorHandler, by the way, for "releases" ?
(I don't recommend enabling it while writing/debugging, though ^^)

Yes, you're right, I'll  do that 




@LDStudios: First, thanks for all the good suggestions and reports!

-Custom Libraries, with Adriweb's Better Lua API as a built in library. Also the ability to add other libraries of your own.

Sorry, but I don't like the idea of a special environment. I want to keep the compatibility of the script as it is to any emulator. But you could pack the library into a library file and load it in your script! Another option would be, that I'll implement the option of setting a custom standard "Header" which is inserted in every new file you create. (Sorry, my english is bad today  )

-Ability to  click the X in the top right of the customize box
-Ability to mark check boxes with cursor as well as buttons

This is both already possible; it's just nearly impossible to aim correctly with the "text" cursor. But, as you mentioned, I'll change to the default cursor for dialogues in future

-The application that runs the script didn't work for me until I clicked on the page, after the first time it worked fine

That's probably because the console application was focused. That's not really a bug, because the execution of the script in the user script page is triggered by the "on.activate" event, which is only triggered if it's application is focused.

-Ability to save custom themes

Indeed, it works fine on the emulator but doesn't on the handheld. The problem seems to be that var.recall apparently doesn't work in the first call of on.activate. I hate that TI doesn't mention such things in their guide and have such differences between emulator and handheld...    I'll try to find an other suitable event for initialization that fits all needs then... 

Also, how did you use ctrl+M to select the line?

ctrl+M triggers the on.createMathBox event on OS>3.1

I added all the other things you wrote to my todo-list
