Wow, maybe this should have been obvious but I didn’t realise that until now. That’s so cool!
I’m working on a slack bot and need to parse people’s commands to the bot. So I’ll be dealing with a lot of strings - and knowing that pattern matching works for this data type is cool!!
You have to use the concatenation operators.
iex(1)> ex_string = "hello elixir" "hello elixir" iex(2)> "hello" <> language = ex_string "hello elixir" iex(3)> language " elixir"
I guess it’s like matching on a list… you have the head and the rest.
So this one won’t work:
iex(4)> greeting <> " elixir" = ex_string 🧨
