[erlang-questions] Why do "interface to language X" projects all seem to die out?

[Michael Truog]

py_interface is GPL, which may explain less use
(I did https://github.com/okeuday/erlang_py/ to make sure I had a BSD licensed dependency)
edtk depended on an obscure scripting language
(I did https://github.com/okeuday/GEPD/ to get EDTK functionality that only depends on the preprocessor, however clang doesn't like boost preprocessor yet, haven't needed to add NIF generation to it)

Other interface to language X projects that are alive include
http://cloudi.org (C/C++, Erlang/Elixir, Java, JavaScript/node.js, Perl, PHP, Python and Ruby)
https://github.com/okeuday/erlang_rb
https://github.com/okeuday/erlang_js
https://github.com/okeuday/erlang_pl
https://github.com/okeuday/erlang_php
