Welcome to the Monastery Ethen

As GrandFather has already suggested
"you should be able to run your Perl application by simply typing the filename on the command line"

You may find it useful when first learning to create a shortcut to the copy cmd.exe into the Perl bin.

Then all that is needed is to type the file name "proj.pl" at the command prompt.

[ambrus]: Corion: from the docs, it definitely looks like it would be possible to write an AnyEvent driver for it using Prima::File and Prima::Timer.
[ambrus]: (I haven't found an idle event.)
[ambrus]: However, I also looked at the internals, and found two interesting things:
[marto]: stupid xpath question, I have a xpath copied from the browser, is the * wildcard supposed to work for IDs? e.g. '//*[@id="*"]/ div/div/header/p/a '?
[ambrus]: The main loop for unixish systems is in https://metacpan. org/source/ KARASIK/Prima-1. 49/unix/apc_app.c. It is a hand-rolled select loop, but also always spins at least once every 0.2 seconds for some reason.
[ambrus]: marto: no, not that way. if you just want to test for an existing id attribute, then write *[@id] , or you can match a regexp to the value of that attribute like *[@id=~/something/ ]
[marto]: ambrus, thanks I ended up going with '//*[starts- with(@id, "thread_")]...
[ambrus]: Sometimes it's easier to just match elements in ways other than xpath, like directly with perl code.
