[jdporter]: one prog I have has a UI which allows to input a bit mask
[jdporter]: currently it expects the bitmask to be in the form of a hex number, e.g. 0x0101
[jdporter]: but I'd like to let the user specify it as individual bits, i.e. 0b0000000100000001
[jdporter]: there is no bit/binary equivalent of hex, right?
[jdporter]: I guess that the most direct way of doing it is with some magical incantation involving unpack or whatever
[jdporter]: let me google that for me ;-)
[jdporter]: hex points explicitly to oct, which does the job. :-D
[jdporter]: omg, I f love Perl!
[choroba]: say unpack 'H*', pack 'B*', $mask =~ /0b([01]+)/;
