You can use PetitPreprocessor: Gofer new squeaksource3: 'PetitPreprocessor'; package: 'PetitPreprocessor'; load

Now it's just transform a matching regex to a substitution String (MyParser preProcess: ('toPreprocess' asRegex) into: 'preProcessed' ) but I plan to improve it by providing a PParser to detect a matching and apply its transformation block (myParser preProcessor: (matchingParser ==> [:m | ..... ])).

Maybe you can use a -completely separate- pre-parser? :)

It takes the input with the pre processor directives, and answers a new processed string which the original parser will handle?.

Hi

What is the best way to handle pre-processor directives with PetitParser without polluting the parsing too much? Any suggestions?

unit forms; interface {$IFDEF WINDOWS} uses bla; {$ENDIF} {$IFDEF LINUX} uses bla2; {$ENDIF}
