estr is an Erlang adaptor for Elixir.String,
Elixir strings are UTF-8 encoded binaries. Read the docs for Elixir.String to know more.
estr bundles a few select .beam files from Elixir, and provides a more
Erlangy API.
These Elixir beam files were taken from an Elixir 1.4.0 build on 64-bit Ubuntu Linux,
circa Feb. 2017.
I have only tested this with Erlang 19.2. It probably works with earlier versions.
You can include this as you would any dep, and have utf8 binary strings in your erlang.
The estr application has no processes or supervisors.
$ rebar3 shell
1> estr:new("Hello").
<<"Hello">>
2> estr:new(<<"Hello">>).
<<"Hello">>
3> estr:next_codepoint(estr:new("жen")).
{<<208,182>>,<<"en">>}
4> S = estr:new("Джубадзе").
<<208,148,208,182,209,131,208,177,208,176,208,180,208,183,208,181>>
5> estr:length(S).
8
6> size(S).
16
7> io:format(estr:to_char_list(estr:upcase(S))).
ДЖУБАДЗЕ
To check estr can call Elixir.String without crashing:
