Not My Type - Perl

Perl has always been known for its text processing and manipulation abilities. This article examines the Perl string handling API in greater detail, explaining how you can use Perl's string functions to (among other things) print and format strings, split and join string values, alter string case, and perform regular expression searches.

TOOLS YOU CAN USE

The chr() and ord() functions come in handy when converting from ASCII codes to characters and vice-versa. For example,


#!/usr/bin/perl # returns "A" print chr(65); # returns 97 print ord("a");
If you prefer numbers to letters, you can use the hex() and oct() functions to convert between decimals, hexadecimals and octals.

#!/usr/local/bin/perl #returns 170 print hex(AA); # returns 40 print oct(50);
And if you ever find the need to reverse a string, well, you can always reach for the reverse() function...

#!/usr/bin/perl $str = "Wassup, dood?"; # reverse string # $rts now contains ?dood ,pussaW $rts = reverse($str); # returns "Sorry, you seem to be talking backwards - what does
# ?dood ,pussaW mean?"
print "Sorry, you seem to be talking backwards - what does $rts mean?";
