[Tutor] 2 functions- are they state machines?

[Kirk Bailey]

These attack a subset of the task.

# This one turns wikiwords into http links
def createwikilinks(line):	# is this a state machine?
	line=string.split(line)
	index=0
	for word in line:
		if wikiname(word):	# ware wordwrap!
			word='<a \
href=http://www.'+domainname+'/cgi-bin/wikinehesa.py/'+\
word+'">'+word+'</a>'
			line[index]=word
			index=index+1
	line-string.join(line)
	return line
	
# this one determines if a word is a wikiword.
def iswikiname(word):			# is this a state machine?
	transitions=0			# counts transitions
	prior=0				# maintains priorletterstate
	caps='ABCDEFGHIJKLMNOPQRSTUVWXYZ' # defines capital letter.
	for letter in word:		# check each letter 4 capitals
		if letter in caps: 	# if this letter is a cap;
			if prior==0:	# if the last was not a cap,
				prior=1	# note a cap was just processed
			else:			# if the last was a cap,
				pass		# noop prior already set
		else:		# if the current letter is not a cap;
			if prior==1: 	# if the last one was a cap;
				transitions=transitions+1 # a transition
				prior=0	# note this letter was not a cap
			else:			# but if not...
				pass		# shine it on...
	if transitions>1:			# 2+ is a wikiword
		return 1			# return a logical YES
	else:					#
		return 0			# return a logical NO
