[Proposal] Macro.camelize support lower camel case

[최병욱]

Hi everyone,

Background

Macro.camelize/1 is convert string to upper camel case (pascal case).

How do I convert lower camel case (camel case with the first letter lowercase) 

Proposal

@spec camelize(String.t(), boolean()) :: String.t()
  def camelize(string, upper? \\ true)

Example

Macro.camelize("foo_bar")

> "FooBar"

Macro.camelize("foo_bar", false)

> "fooBar"

Macro.camelize("d_day", false)

> "dDay"

What is your opinion :)

Hey there, I think that would be a nice addition in general, but Macro.camelize/1 has a very specific purpose:

This function was designed to camelize language identifiers/tokens, that's why it belongs to the Macro module. Do not use it as a general mechanism for camelizing strings as it does not support Unicode or characters that are not valid in Elixir identifiers.

​

If you take look at the source code, you will see that camelization will work only on ASCII strings, and with "_" as delimiters, but it shouldn't too hard to write camelize/2 that suits your needs.
