Methods to cut strings

The two methods—chop and chomp—have similar names but have a different sensitivity to the characters they work with. The chop method cuts out the last character of the string. The chomp method only cuts the last character if it is a newline character.

say "Text\n".chomp; # Textsay "Text\n".chop;  # Textsay "Text".chomp;   # Textsay "Text".chop;    # Tex

Another group of methods—trim, trim-leading, and trim-trailing—cuts the spaces at the beginning and/or end of the string. Consider the following code snippet:

my $s = ' word '.trim;say "[$s]"; # [word]$s = ' word '.trim-leading;say "[$s]"; # [word ]$s = ' word '.trim-trailing;say "[$s]"; # [ word]
