What does {parse_transform, do} do?

[RamzyVirani]

Hi, I am trying to compile this project with Erlang 9.2 on Windows 10. I have rebar version rebar 2.6.4 20 20180205_205652 No VCS info available.

I am getting below error when compiling your project.

src/tcp_listener.erl:none: undefined parse transform 'do' Compiling src/tcp_listener.erl failed: ERROR: compile failed while processing F:/erlangProjects/erlstund: rebar_abort

when I tried to comment the {parse_transform, do}, I got below error.

src/tcp_listener.erl:139: function do/1 undefined Compiling src/tcp_listener.erl failed: ERROR: compile failed while processing F:/erlangProjects/erlstund: rebar_abort
