paiza.ioでelixir その56

概要

paiza.ioでelixirやってみた。
Regex.named_captures使ってみた。

サンプルコード

Regex.named_captures(~r/A(?<hoge>.+)C/, "A0bCA1bCA2bCA3bCA4bC")
|> IO.inspect

string = "Here is my phone number: 999-111-1234"
regex = ~r/number: (?<phone>[\d|-]+)/
Regex.named_captures(regex, string)
|> IO.inspect

regex = ~r"\[tag1\](.+?)\[\/tag1\]"
Regex.run(regex, "[tag1]bar[/tag1]")
|> IO.inspect
Regex.scan(regex, "[tag1]bar[/tag1] [tag1]baz[/tag1]")
|> IO.inspect

Regex.named_captures(~r/A(?<hoge>.*)C/, "A0bCA1bCA2bCA3bCA4bC")
|> IO.inspect

Regex.named_captures(~r/(?<name>\w)/, "ab")                    
Regex.scan(~r/\w/, "ab") 
|> Enum.map(fn x -> 
    %{name: hd(x)} 
end) 
|> IO.inspect

Regex.scan(~r/\w/, "ab") 
|> List.flatten
|> IO.inspect

Regex.named_captures(~r{(?<protocol>http://|https://)(?<domain>.*)}, "https://qiita.com")
|> IO.inspect

Regex.named_captures(~r[Guard #(?<guard_id>\d+) begins shift], "[1518-11-01 00:00] Guard #10 begins shift")
|> IO.inspect
			
Regex.named_captures(~r/(?<minus>-?)(?<digit>[[:digit:]]*)(?<frac>\.?[[:digit:]]*)(?<exp>[eE]?[-+]?[[:digit:]]*)(?<rest>.*)/s, "12345")
|> IO.inspect
Regex.named_captures(~r/(?<minus>-?)(?<digit>[[:digit:]]*)(?<frac>\.?[[:digit:]]*)(?<exp>[eE]?[-+]?[[:digit:]]*)(?<rest>.*)/s, "12:45")
|> IO.inspect
Regex.named_captures(~r/(?<minus>-?)(?<digit>[[:digit:]]*)(?<frac>\.?[[:digit:]]*)(?<exp>[eE]?[-+]?[[:digit:]]*)(?<rest>.*)/s, "12.45")
|> IO.inspect
Regex.named_captures(~r/(?<minus>-?)(?<digit>[[:digit:]]*)(?<frac>\.?[[:digit:]]*)(?<exp>[eE]?[-+]?[[:digit:]]*)(?<rest>.*)/s, "1.2e+4")
|> IO.inspect
