Right now the great problem is files that look like this: .......... .......... self.assertEquals(x, y) # check for unmatched () ......... where the last ')' in the comment is the one that gets split and multi-line comments that start self.assertEquals t.ex ''' Here is something which will confuse things a lot self.assertEquals(x, y) will be converted to assert x == y ''' Right now my program will mistake that for program text to be converted. I wonder if this is a real problem for us? Also, the compile needs to get a string with the leading indentation stripped right off, i.e. self.assertEquals(x + f(y, z) + (z + 1), 42) needs to make the strings x + f(y, z) + z + 1 and 42 so as not to get a syntax error on the unexpected indentation. I wonder if we have text where people mix spaces and tabs on the leading line on purpose? If so my program is going to despair and demand a human to fix it. I will get done making dinner, then check in what I have. It was rather fun ... Thank you Armin for the idea over dinner ... Laura [View Less]

Wow. The world is over indeed. At any rate, it looks like I might get to write soem code today after all. My idea is to take the builditn checker and make it spit out html. I know very little about generating html, but Ihave some nice books here. Of course, what would be best is if you already had a page that mostly did what you want this page to do, so I could simply 'make one like that'. Anybody got a candidate?
