regex - simple Perl regular expression -


hi i'm quite new perl , seeking parse simple line of code.

what need parse in of 

#include "filename"

i need regular expression file name.

i know there's split method in python this, don't know if there's similar func in perl

thanks

you could split in perl:

my $fn = (split('"', $include_line))[1];

...but that's pretty obtuse way of going it. i'd opt for

my ($fn) = $line =~ /^#include +"([^"]+)"/;

instead, clearer , has advantage of returning nothing on non-#include lines rather returning false positives if input file contains other lines double-quoted text.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
