Hi Terry! I have used Twisted for some small web development (mainly for practice) and for some big application writing (I used it successfully to write a complete GPS data gathering application, that's been running for about 10 months straight now, nonstop).
Well, the main difference I see between TG and Twisted, is the ease of use, and cut in development time. In fact, when you work with Twisted, you have to know a *LOT* (as compared with *nothing* in TG) about the internals of Twisted to get started, and you need to add the bits and pieces by hand. The main "small differences" I see are: 1) TG uses the CherryPy server, which has been used and tested extensively by a lot of programmers, not just inside TG. 2) TG comes with ready to use AJAX support, something Twisted/Nevow doesn't have (in fact can be added quite easily). 3) TG is built around SQLObject, which makes it pretty easy to use SQLObject, but of course you can use any engine you want (but you won't have support from CatWalk, etc). 4) Twisted docs are much more extensive than TG's, but understanding the framework requires more than reading the docs (you'd have to read some code as well). 5) Twisted's community is somewhat active (just enter #twisted in irc.freenode.net) but the code is maintained by just 2 or 3 coders. The code base is more mature, but I see that it's somewhat biased and some of them are quite ... well, I wouldn't use the word 'zealots', but if you ask for support under Win32 they would tell you "ah... don't know, I *NEVER* use Win32, I'm l337". 6) Writing code that works in TG is much simpler, making the signal/noise ratio of your code much higher. If you want to load a template and fill it with some data you get from a DB in TG you are just required to write about 5 lines of code, while the same work in Nevow could take much more. So, in a general way, use TG if you want to start coding right away and have some working site in less than a week. Use Twisted if you feel confident enough, feel eager enough to learn a lot of things, and want to write code for the ages. About a review... well, Guido van Rossum sparked a little controversy when he said that he didn't like none of the current frameworks in his personal blog, but you could read the thread to find pointers and discussion about different frameworks (that was, in the end, what the post was all about). You can find the post and comments here: http://www.artima.com/weblogs/viewpost.jsp?thread=146149 Last but not least, seemingly you want to have a web framework with "no frills", maybe you should give web.py a look. Personally I don't like it very much, and it doesn't have much documentation (or any documentation at all) at this time, but it was used to build http://reddit.com and seems to work pretty well under high loads. Hope this helps you, and good luck. David Guaraglia Terry Jones wrote: > I've been on the TG list for just a few days.
