With a block given, forms the substrings ("lines")
|
|
that are the result of splitting +self+
|
|
at each occurrence of the given line separator +line_sep+;
|
|
passes each line to the block;
|
|
returns +self+:
|
|
|
|
s = <<~EOT
|
|
This is the first line.
|
|
This is line two.
|
|
|
|
This is line four.
|
|
This is line five.
|
|
EOT
|
|
|
|
s.each_line {|line| p line }
|
|
|
|
Output:
|
|
|
|
"This is the first line.\n"
|
|
"This is line two.\n"
|
|
"\n"
|
|
"This is line four.\n"
|
|
"This is line five.\n"
|
|
|
|
With a different +line_sep+:
|
|
|
|
s.each_line(' is ') {|line| p line }
|
|
|
|
Output:
|
|
|
|
"This is "
|
|
"the first line.\nThis is "
|
|
"line two.\n\nThis is "
|
|
"line four.\nThis is "
|
|
"line five.\n"
|
|
|
|
With +chomp+ as +true+, removes the trailing +line_sep+ from each line:
|
|
|
|
s.each_line(chomp: true) {|line| p line }
|
|
|
|
Output:
|
|
|
|
"This is the first line."
|
|
"This is line two."
|
|
""
|
|
"This is line four."
|
|
"This is line five."
|
|
|
|
With an empty string as +line_sep+,
|
|
forms and passes "paragraphs" by splitting at each occurrence
|
|
of two or more newlines:
|
|
|
|
s.each_line('') {|line| p line }
|
|
|
|
Output:
|
|
|
|
"This is the first line.\nThis is line two.\n\n"
|
|
"This is line four.\nThis is line five.\n"
|
|
|
|
With no block given, returns an enumerator.
