def each_line(...) # :yield: line
File.foreach(@path, ...)
end
With a block given, calls the block with each line from the file represented by self; returns nil:
Example
lines = [] Pathname('COPYING').each_line {|line| lines << line } lines.take(3) # => # ["{日本語}[rdoc-ref:COPYING.ja]\n", # "\n", # "Ruby is copyrighted free software by Yukihiro Matsumoto <[email protected]>.\n"]
The lines are read using IO.foreach, all arguments and options are passed to that method; see details at IO.foreach.
With no block given, returns a new Enumerator.
