mr2 has asked for the wisdom of the Perl Monks concerning the following question:


i need to write 2 scripts that must comunicate on the same server ...

one gathers some information & it needs to give it (some
data) to another script that posts this data somewhere ...
(everything in real time)

any suggestions how to do it & what modules to use?

thanks

    I would start by reading perlipc (man perlipc) and see what ideas pop up.

    I accomplished something similar on a project by using Cache::Cache.

    It's a good pretext to use SOAP::Lite ;-)
    A nice and small project to get familiar with the technology (that is extremely simple to use in Perl.

    Just my 2 cents, -gjb-

    Well, IPC::Shareable saved my butt a few times but I do consider using it as a dirty hack :)

    Lots of ways to do this, here's the ones I remember off the top of my head, pick one you like:

    • Look for files in a directory/drop files in a directory (good when data is in obvious chunks like transactions, and/or you're in a hurry.)
    • Create a pipe. One process writes to it, the other reads. If you need bi-directional, two pipes. (This is classic *nix.)
    • If there is a future possibility of the two processes being on different machines, consider using a socket.
    • I haven't used SOAP::Lite, but a couple other posters mention it, so it's probably worth checking, especially if your project needs more buzzwords for PHB approval.

    Also, if there is a future possibility of needing more than one instance of either end of the protocol, keep that in mind in picking a solution.
