in reply to Perl, the right tool for the job?

This question is silly on multiple levels:

  • You don't pick tools and then try to fit them to the problem. You specify the problem as well as you can and then identify the correct tools.
  • "...for this I can't use Perl." Why are you asking this question in Perlmonks then?
  • "...communicate to a server"..."over bluetooth or wireless lan"..."server process just interacts with...command line tools..." Pretty much every toolkit for mobile devices can communicate via bluetooth and/or wireless LAN and every language worth learning or using can shell out to utilize 'command line tools.' That is not a specification. That is like saying 'I need an elephant for my parade' only to be surprised when someone arrives with an eight inch toy elephant.
  • "..what do I need to read up on..." I can help you here. Perl is not the right tool for your task. Your task requires someone to do your work for you and to help you do your research and thinking. There are many toolsets available out there that purport to do exactly that. You should use one of those.

[ambrus]: Corion: I think I parsed a HTTP header from a string with LWP once. You can definitely use that to create a HTTP message too. The problme is
[ambrus]: that if you do that, you'd have to find where each HTTP response ends, which is nontrivial if you want persistent connections (essential for performance if you have small requests).
[Corion]: ambrus: Yes, ideally an API that I feed the incoming data piece by piece and that I can ask "is that response done" and "what should I do next" and "please construct the appropriate redirect for me"
[Corion]: ambrus: Yes, ideally the module would do all that nasty stuff for me and give me a way to ask it what the current situation is
[ambrus]: Corion: you could also consider using some wrapper over the multi interface of curl, I think Net::Curl might be a good one, since implementing enough of what it expects from the event loop might be easier than a full AnyEvent interface.
[ambrus]: Corion: you could also consider using IO::Async and its POE driver and some HTTP module for it, but I don't know if that would solve your problems with AnyEvent+POE
[ambrus]: Corion: wait, you didn't say POE. You said Prima, let me look up what that is.
[ambrus]: Corion: have you considered just writing an AnyEvent integration for that thing?
[ambrus]: Or perhaps pushing schmorp to write one?
[ambrus]: Also, searching for an existing one on CPAN obviously
