difference in editor to script-match

[levlum]

dear ohm people,

i am very greatful to your work and ohm. it is wonderful. i write a simple scripting language for pupils to handle our most simple game engine.

now, i have a problem and i can not figure it out by myself. i can not find an answer, i really tried hard.

below is my simple grammar so far. in the editor it works great with additional spaces. but when i try to call match on my page then it does not succeed with any additional space.

test script (with spaces at the beginning of both lines):
wiederhole 15 mal hinunter 4 wiederhole immer rechts 5

the test script does succeed in the ohm-editor but not on in my script. why is that?
thank you very much for your help!
all the best and good days,
lev

SchubuScript {
Script = ScriptPart+ end
ScriptPart = Befehl | Event | comment | lineTerminator
LoopBlock = "wiederhole" (endless | int) ("mal")? Befehl
Event = "bei" eventtype type_part? Befehl
Befehl = BewegungsBefehl | Sage | LoopBlock
BewegungsBefehl = ("hinauf" | "hinunter" | "links" | "rechts") kraft
Sage = "sage" stringLiteral

     kraft = digit
     endless = "immer" | "endlos"
     eventtype = 
          ("berührung" | "Berührung") -- collision
        | ("sicht" | "Sicht" ) -- view
        
     type_part = "von "? type
     type =  
          ("ball" | "Ball") -- ball
        | ("wand" | "Wand") -- wall
        | ("ziel" | "Ziel") -- goal
        | ("spieler" | "Spieler") -- player
        | ("tod" | "Tod") -- death
        | "++" -- push
        | ("bot" | "Bot") -- bot
        
     int = digit+
     comment = "//" (~lineTerminator any)* lineTerminator
     space += comment
     lineTerminator = "\n" | "\r" | "\u2028" | "\u2029" | "\r\n"
     stringLiteral = quoteMark (~lineTerminator ~quoteMark any)* quoteMark
     quoteMark = "\""

}

i solved it myself. in the contenteditable div (script window), the css rule: white-space: pre; was necessary.
cheers,
