Method: String#each_line

Defined in:
string.c

#each(separator = $/) {|substr| ... } ⇒ String #each_line(separator = $/) {|substr| ... } ⇒ String

Splits str using the supplied parameter as the record separator ($/ by default), passing each substring in turn to the supplied block. If a zero-length record separator is supplied, the string is split on \n characters, except that multiple successive newlines are appended together.

print "Example one\n"
"hello\nworld".each {|s| p s}
print "Example two\n"
"hello\nworld".each('l') {|s| p s}
print "Example three\n"
"hello\n\n\nworld".each('') {|s| p s}

produces:

Example one
"hello\n"
"world"
Example two
"hel"
"l"
"o\nworl"
"d"
Example three
"hello\n\n\n"
"world"
