twill is completely open source and redistributable etc, unless you're looking to sell it. Then we should talk, or you should have a lawyer check out the license. Adding functions is pretty simple, as long as you don't need to modify the core browser functionality; check out the extensions documentation at http://issola.caltech.edu/~t/twill/doc/extensions.html -> The first function is just forward, it looks like beyond adding -> functions in commands.py and browser.py, the real changes would have to -> be made in _mechanize.py since the History class doesn't seem to have -> any support for going forward.

Is this the right direction for doing this, or am I -> missing something else? Well, what's your goal with this? Right now the history works like a simple stack; it wouldn't be hard to change it to be a list, if that's what you need. You're right that it doesn't get the current page, but twill has that information... so it really depends on what you want to do. -> Second, I would like to be able to follow a link by its number printed -> out after using showlinks. -> -> I added to commands.py: -> -> def followbynum(num): -> """ -> >> follow <link#> -> -> Visit the page at position link# in the list returned by showlinks. -> """ -> -> def follow_link_num(self, linknum): -> """ -> Follow the link by its number on the page. -> """ -> This seems to work right now, but I'm afraid there's something I am -> missing, or some error case that I'm not considering. Nope, it looks good to me! I could add this functionality in to 'follow' 'as is', actually, by just choosing the link by number in 'follow' if it's an integer. Any objections, anyone? cheers, --titus _______________________________________________ twill mailing list [email protected] http://lists.idyll.org/listinfo/twill
