paiza.ioでelixir その54

概要

paiza.ioでelixirやってみた。
String使ってみた。

サンプルコード

String.at("elixir", 1)
|> IO.puts
String.bag_distance("abcd", "abc")
|> IO.puts
String.capitalize("fin")
|> IO.puts
String.chunk(<<?a, ?b, ?c, 0>>, :valid)
|> IO.puts
String.codepoints("\u003c")
|> IO.puts
String.contains?("elixir of life", "of")
|> IO.puts
String.downcase("ABCD")
|> IO.puts
String.duplicate("abc", 2)
|> IO.puts
String.ends_with?("language", "age")
|> IO.puts
String.equivalent?("abc", "abc")
|> IO.puts
String.first("elixir")
|> IO.puts
String.graphemes("\u003e")
|> IO.puts
String.jaro_distance("Dwayne", "Duane")
|> IO.puts
String.last("elixir")
|> IO.puts
String.length("elixir")
|> IO.puts
String.match?("foo", ~r/foo/)
|> IO.puts
string1 = "fox hops over the dog"
string2 = "fox jumps over the lazy cat"
String.myers_difference(string1, string2)
|> IO.inspect
String.next_codepoint("olá")
|> IO.inspect
String.next_grapheme("olá")
|> IO.inspect
String.next_grapheme_size("olá")
|> IO.inspect
String.normalize("fi", :nfkc)
|> IO.puts
String.pad_leading("abc", 5)
|> IO.puts
String.pad_trailing("abc", 5)
|> IO.puts
String.printable?("abc")
|> IO.puts
String.replace("a,b,c", ",", "-")
|> IO.puts
String.replace_leading("hello world", "hello ", "hi ")
|> IO.puts
String.replace_prefix("world", "hello ", "")
|> IO.puts
String.replace_suffix("hello", " world", "")
|> IO.puts
String.replace_trailing("hello world", " world", "")
|> IO.puts
String.reverse("abcd")
|> IO.puts
String.slice("elixir", 1..3)
|> IO.puts
String.slice("elixir", 1, 3)
|> IO.puts
String.split("foo bar")
|> IO.inspect
String.split("a,b,c", ",")
|> IO.inspect
String.split_at("sweetelixir", 5)
|> IO.inspect
String.splitter("1,2 3,4 5,6 7,8,...,99999", [" ", ","]) 
|> Enum.take(4)
|> IO.inspect
String.starts_with?("elixir", "eli")
|> IO.puts
String.to_atom("my_atom")
|> IO.puts
String.to_charlist("æß")
|> IO.puts
_ = :my_atom
String.to_existing_atom("my_atom")
|> IO.puts
String.to_float("2.2017764e+0")
|> IO.puts
String.to_integer("123")
|> IO.puts
String.to_integer("3FF", 16)
|> IO.puts
String.trim("\n abc\n  ")
|> IO.puts
String.trim("a  abc  a", "a")
|> IO.puts
String.trim_leading("\n  abc   ")
|> IO.puts
String.trim_leading("__ abc _", "_")
|> IO.puts
String.trim_trailing("   abc\n  ")
|> IO.puts
String.trim_trailing("_ abc __", "_")
|> IO.puts
String.upcase("abcd")
|> IO.puts
String.valid?("a")
|> IO.puts
