instance method Pathname#each_line

each_line(*args) {|line| ... } -> nil[permalink][rdoc]

each_line(*args) -> Enumerator

IO.foreach(self.to_s, *args, &block) と同じです。

例

require "pathname"

IO.write("testfile", "line1\nline2,\nline3\n")
Pathname("testfile").each_line
# => #<Enumerator: IO:foreach("testfile")>

例 ブロックを指定

require "pathname"

IO.write("testfile", "line1\nline2,\nline3\n")
Pathname("testfile").each_line {|f| p f }

# => "line1\n"
# => "line2,\n"
# => "line3\n"

例 limit を指定

require "pathname"

IO.write("testfile", "line1\nline2,\nline3\n")
Pathname("testfile").each_line(4) {|f| p f }

# => "line"
# => "1\n"
# => "line"
# => "2,\n"
# => "line"
# => "3\n"

例 sep を指定

require "pathname"

IO.write("testfile", "line1\nline2,\nline3\n")
Pathname("testfile").each_line(",") {|f| p f }

# => "line1\nline2,"
# => "\nline3\n"
