a little somethin' for jemfinch (and whoever else wants it)...

[inkedmn]

here's the code for cfactive (checks to see what users are active here on cf.net)


#!/usr/bin/env python

import urllib
import sys
import re

def cfactive():
url = 'http://www.coderforums.net'
try:
source = urllib.urlopen(url)
except Exception:
print "error"
sys.exit(1)
html = source.read()
lines = re.sub('<.*?>', '', html)
lines = lines.split('\n')
for i in range(len(lines)):
if lines[i].strip().split(' ')[0] == 'Most':
data = lines[i+1].strip()
print data
break


enjoy :)

[jemfinch]

It's in! The first submission from someone other than me for the bot!

Oh, it feels good to be able to put stuff in the bot without having to test and debug it myself :D

Here's what I actually put in, and my comments relating to the places I changed things. I'm getting some strange behavior, but it might just be because of the changes I made, I'll have to check.


_removeHtml = re.compile('<.*?>')
def cfactive(self, irc, msg, args):
"takes no arguments."
try:
fd = urllib2.urlopen('http://www.coderforums.net/')
except Exception, e:
self.error(debug.exnToString(e))
text = fd.read()
text = self._removeHtml.sub('', text)
lines = text.splitlines()
for i in range(len(lines) - 1):
if lines[i].strip().startswith('Most'):
self.reply(lines[i+1].strip())
self.error('The format of the page seems odd.')


I changed a few variable names; obviously, that's a personal issue, and I just wanted the variable names to match what I use in the rest of the program.

I stored my own compiled copy of the regular expression. Python keeps a cache of the most recently used compiled regexps, but I never want to rely on that, since I don't know its exact behavior.

I used the string method "splitlines" instead of splitting on a newline, since splitlines should be written in C, and thus a bit faster. It's also easier to type (for me) and obvious in its purpose. It also handles line endings other than just '\n', depending on what OS you're using.

The for loop has an off-by-one error. If the last line is the first line to start with "Most", then you'll try to reference an element not in the list and raise IndexError. I fixed that.

I changed " .split(' ')[0] == 'Most' " to ".startswith('Most') " -- I haven't checked to make sure it'll work, but from the looks of the code, there's no reason it shouldn't. That should be slightly more efficient and easier to read.

And, of course, I changed the printing error messages to send IRC messages instead :)

Thanks a bunch for the command! I look forward to getting even more commands that I didn't have to design and debug myself :) After that crazy forums.py module, I don't know how ready I am to jump back into downloading files, looking for information, and sending it back.

kmj showed me my change that broke it, so I fixed it :) I left out your "break" on accident :)

[inkedmn]

glad you're able to use it :)

let me know if there's anything else i can do for you...

[inkedmn]

here's one more :)


#!/usr/bin/env python

import urllib2
import string
import sys

def stockQuote(symbol):
base = 'http://finance.yahoo.com/d/quotes.csv?s='
tail = '&f=sl1d1t1c1ohgv&e=.csv'
url = base+symbol+tail
try:
quote = urllib2.urlopen(url).read()
except Exception, e:
print e
sys.exit()
splitquote = quote.split(',')
if splitquote[1] != "0.00":
print "The current price of %s is $%s - as of %s EST, a change of %s from the last business day" % \
((splitquote[0])[1:-1] , splitquote[1], splitquote[3][1:-1], splitquote[4])
else:
print "Sorry, I couldn't find a listing for %s" % symbol.upper()


have fun :)

Jemfinch, I thought you stuck to the PEP style guidelines for the most part, triple quote that docstring ;)

jemfinch: first submission for supybot was my version thingie from freshmeat which you did not take at the time since you had not implemented threaded callbacks.

[GnuVince]

WTF is going on with Supybot? I need to start it, Ctrl-C (big callback error) and then start it again for it to work. This is dumb.

Oh and I'm testing a foldoc method.

[GnuVince]

def _index(self, lst, element, n=1):
m = 0
for i in xrange(len(lst)):
if lst[i] == element:
m += 1
if m == n:
return i

def foldoc(self, irc, msg, args):
"<software>"
s = self.getArgs(args)
soft = '+'.join(args)
url = "http://foldoc.doc.ic.ac.uk/foldoc/foldoc.cgi?query=" + soft
html = urllib.urlopen(url).readlines()
if re.search('No match for', html[2]):
self.reply("%s doesn't exist on Foldoc" % args[0])
else:
start = self._index(html, '

\n', 1)
stop = self._index(html, '

\n', 2)
descr = ' '.join(html[start:stop]) # Get base description
descr = re.sub('\n', '', descr) # Remove newlines
descr = re.sub('<.*?>', '', descr) # Remove HTML tags
descr = re.sub('&.*;', '', descr) # Remove HTML tags
descr = descr.lstrip() # Remove leading white spaces
self.reply(descr)


Try this out.

[jemfinch]

I can't do much without seeing the exception, GnuVince :)

And the big bad error message:

That looks like a network problem to me, GnuVince...I'll have to wait until I get some more instances of that problem before I really spend some time on it.
