in reply to Re: readline() on closed file-handle is coming when reading the file
in thread readline() on closed file-handle is coming when reading the file

Or, even better:

or die "Cannot open file: $!";

so that you can see the o/s error generated when the filehandle failed to open.

Cheers,

[ambrus]: Corion: as for that, I talked with schmorp, and looked a bit more at Prima
[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/ ]
