Try it you'll like it. I certainly do. It takes a little bit to get used to but the shortcuts for creating multiple table rows and table data are invaluable. I certainly don't know all it can do but the little that I do know sure seems to go a long ways. It is also easy to switch from using CGI.pm notation for HTML to simple here documents, if I want to write out HTML by hand.

    Personally, I use a mix of it, pending on what i shall do and who i am writing it for. Sometimes I find it easier to use the HTML tags rather than the shortcuts, especially when i make complicated tables.
    And there's always the option of a external HTML file and use regexps to insert variables:
    open(HTML, "<a_file.html") or die "cant open HTML file: $!\n"; while($row = <HTML>) { $row =~ s/---(.*?)---/eval $1/eg; print $row; } close HTML;
    Which will look for ---$variablename--- in the HTML code and replace it with the variable (as if you didnt know ; )) I also use HTML comment flags to insert more complicated structures. I've written a rather simple Web-based discussion forum using this technique, which allows the administrator of the site to change the design without knowing any Perl at all.
      At one place I worked, we found the template idea to be the most flexible way of doing it -- namely because then we could use the same subs for filling out not only HTML but reports written in LaTeX, E-Mail reports, etc.

      I myself started out using CGI.pm, then as time went on used less and less of it until I finally just kicked in a sub to parse the parameters and left out the module completely. I guess I'm just obsessive about my HTML :)

[Corion]: ... or so I think. As I said, I'm somewhat vague on how to make AnyEvent cooperate with a callback-driven IO event loop that gives me callbacks when data is available or can be written
[ambrus]: what push_write thing? I don't think you need that. that's implemented generically by AnyEvent::Handle
[Corion]: ambrus: Yeah, that's what I think as well. But you give me an idea, maybe I should start with implementing the timer, as that should be far simpler and with fewer edge-cases/nasty interaction than the file watcher
[ambrus]: You only provide the watcher part that tells when the handle is readable or writable, not the actual writing and reading.
[Corion]: ambrus: Hmmm. It makes sense that AnyEvent would implement the push_write itself, but I think I don't have a good idea of where the boundary between AnyEvent and the underlying event system lies... Implementing the timer should give me a better idea
[ambrus]: Corion: push_write is in the higher level abstraction of AnyEvent::Handle, not in the watcher
[Corion]: ambrus: Hmm - rereading Prima::File, that merrily coincides with what Prima does - it tells you "you can read", and you're supposed to read from the fh yourself. I thought it called you with the data already read, which would've been harder to integrate
[ambrus]: you just need an io watcher, created by &AnyEvent::Impl:: Whatever::io(...)
[Corion]: So after talking it through with you even while I'm still not entirely clear on where AE ends and my implementation begins, I think I understand that I only need to implement some smaller parts for each functionality I want to support.
[Corion]: Yeah... and you might even be able to mix and match additional functionality if you have additional async suppliers, like from a separate thread
