When I was doing programming competitions at uni, I wrote this script, which takes the default HTML output from PC^2 and add some colour to it to indicate passed / failed problems. Since it was written / enhanced on the day of the competition, there’s definitely some hacky code in there, but I’m publishing it so future generations can steal it for their own nefarious purposes.
This code is released into the public domain.
# prettify.py
import re
import string
import sys
from lxml import html, etree
doc = etree.parse(open('prettify.xsl', 'rU'))
xslt = etree.XSLT(doc)
doc = html.parse(sys.stdin)
passed = re.compile('^[0-9]*/[1-9][0-9]*$')
failed = re.compile('^.*[1-9]/[-0]*$')
for node in doc.xpath('//td'):
text = node.text or ''
if passed.match(text):
node.attrib['class'] = 'passed'
elif failed.match(text):
node.attrib['class'] = 'failed'
problems = dict(zip(string.uppercase, [
'An Industrial Spy',
'Simple Polygon',
'High Score',
'Rankings',
'Wormholes',
'Fractal',
'Rewards for Math!',
'Divisible Subsequences',
]))
for node in doc.xpath('//th/strong/u'):
node.text = problems.get(node.text, node.text)
doc = xslt(doc)
#body = doc.xpath('//html/body')
#d = etree.Element('div')
#d.attrib['class'] = 'timer'
#
#import sys
#from datetime import datetime
#n = datetime.now()
#t = datetime(2011, 9, 3, 17, 0, 0, 0)
#print>>sys.stderr, n - t
print html.tostring(doc)
