Hi
i have found a free editor for windows which can be used to edit ,run, syntax coloring, the perl6 code in a comfortable way.
here are the detailed steps from a newbie :
1- for the current may-june 2010 version ,download the following for windows from here:
http://sourceforge.net/projects/parrotwin32/files/
download setup-parrot-2.4.0.exe 8 MB
download setup-parrot-2.4.0-rakudo-29.exe 1 mb
download other addons if you want which have the same 2.4.0 number
after installation check to see if you can run perl6.exe from any directory , it is in the bin folder in Parrot-2.4.0 folder.
the recent 2.4.0 version needs libgcc_s_sjlj-1.dll download it from here....
i have found it in a program called "HandBrake-0.9.4-Win_GUI"
i hope it will be corrected in the next releases.
the editor called Jens' File Editor -The Ultimate Editor for programmers download it from here 1 MB ,2 files, no setup neccessary
http://home.arcor.de/jensaltmann/JFE/jfe_eng.htm
here are 4 images to describe the editor with our context:
jfe1....

jfe1-2....

jfe2....

jfe3....

jfe4....

now download the jfe.ini with runprogram.bat from here
jfe.ini & runprogram.bat
put the two files in the same folder as jfe editor folder
the jfe.ini i have copied from the bcx programming language( a basic to c translator) it contains the sytax coloring and the definitions of the buttons you added, i haven't edited it too much you can add, delete entries as explained in the pictures above.
how to use?? just write some code, save as to the same folder of the jfe, then click the run program button which will call the runprogram.bat file. the contents of the runprogram file is

@ECHO OFF
perl6.exe %1.pl
ECHO.
ECHO.
SET /P M=press ENTER to Exit
:done

it needs your code to be in the same folder of the jfe editor. i will study the batch files commands to be able to run the files in any folder.
also i will try to add the syntax coloring for the huge commands of perl6, and to delete that of the bcx language, the included jfe.ini file is just an example
best wishes
