Hello everyone,
Currently the second argument of funtions String.{trim, trim_leading,
trim_trailing}/2 can only be a string.
I would like Elixir to support a list of strings to be trimmed, such as:
String.trim_leading(tag_name, ["OTP_", "OTP-"])
There is a precedent of other functions taking list of strings as in
the case of `String.starts_with?/2`, `String.end_with?/2` and
`String.contains?/2`.
Currently it can be achieved with `String.replace_leading/3` and
`String.replace_trailing/3` but:
1. by using "" as the replacement it is not as clear as what trim
conveys.
2. There is no direct replacement for `String.trim` and two
function calls are needed:
string |> String.replace_leading([" ", "-", "_"], "") |>
String.replace_trailing([" ", "-", "_"], "")
where with this would suffice.
String.trim(string, [" ", "-", "_"])
Please let me know what you think about it.
