' Whitepace is always allowed. This includes spaces, tabs
|
|
' linefeeds (10) and carriage returns (13)
|
|
'
|
|
' Keys may not have spaces or assignment operator = in them.
|
|
'
|
|
' Comments start with // (unless used within strings)
|
|
' and count as comment for the rest of the line. Or use /* and */ /*
|
|
' to mark the beginning and end of a comment.
|
|
'
|
|
' Simple setting:
|
|
'
|
|
' key = value;
|
|
'
|
|
' Example: speed = 345;
|
|
' cars = 8;
|
|
'
|
|
' Strings must be in quotes.
|
|
'
|
|
' Example: nickname = "Gherkin";
|
|
' altnick = "Gherk inn";
|
|
'
|
|
' String Escape Sequences:
|
|
' \n New line (10)
|
|
' \r Carriage return (13)
|
|
' \t Tab (9)
|
|
' \" Double-quotation mark
|
|
' \\ Backslash
|
|
' \000 Any ASCII character (MUST be 3 digits! So for 13 you use \013)
|
|
'

|
' Decimals ALWAYS use a dot, NEVER comma!
|

' acceleration = 1.0023;
|

'

' true, false and null are valid keywords.

' null values can be left out.

' key

' father = 52;

' father
|
|
