Why bother?  Just shell out to Markdown.pl with OSProcess.  Markdown is a
big ball of complex regex and I don't think Squeak's regex support fully
supports everything Pearl's does.  Add this extension to UnixProcess class
side

pipeString: aString throughCommand: aCommandString 
    | pipe1 pipe2 input output src dest child result delay |
    pipe1 := OSPipe blockingPipe.
    pipe2 := OSPipe nonBlockingPipe.
    input := pipe1 reader.
    output := pipe2 writer.
    src := pipe1 writer.
    dest := pipe2 reader.
    child := self forkJob: aCommandString arguments: nil environment: nil
descriptors: {  input. output. nil  } .
    input close.
    output close.
    src nextPutAll: aString.
    src close.
    delay := 10 milliSeconds asDelay.
    [ child isComplete ] whileFalse: [ delay wait ].
    result := dest upToEnd.
    dest close.
    child sigterm.    "Tell the child to exit"
    ^ result withSqueakLineEndings 

Then you can just do ...

    UnixProcess pipeString: someContent throughCommand: 'Markdown.pl'

And you're good to go, assuming you've put Markdown.pl in your images
directory.
