superport

An erlang port example

Note

Don't use the zig version for the moment. I discovered that never stops. Will remove this note when is ready to be used. Just use the C version.

Build and run

This project contains an erlang port developed with zig language, that does the same as the C version.

If you have zig installed ( I recommend using asdf ), then ...
<BEGINNING OF ZIG setup>
$ cd z_src
(run the tests of zig code [optional])
$ zig src/main.zig
(build the executable)
$ zig build -Drelease-fast=true 
$ cd ..
$ cd priv
$ cp ../z_src/zig-out/bin/eport .
$ cd ..
<END OF ZIG setup>

make sure rebar3 is in you path and ...
$ rebar3 shell
(Let's try first the C version)
1> Path = filename:join([code:priv_dir(superport), "superport"]),
2> superport:start(Path).
(you should see the port displayed)
3> superport:foo(3).
(you should see 4)

4> superport:bar(3).
(you should see 6)

5> superport:baz(3).
(you should see 0)

6> superport:sum(3,2).
(you should see 5)

7> superport:stop().
(Let's try the zig version)

8> Path2 = filename:join([code:priv_dir(superport), "eport"]),
9> superport:start(Path2).
(you should see the port displayed)
10> superport:foo(3).
(you should see 4)

11> superport:bar(3).
(you should see 6)

12> superport:baz(3).
(you should see 0)

13> superport:sum(3,2).
(you should see 5)

14> superport:stop().

exit from rebar3 shell with ctrl-c

or run test ( which uses the erlang port C version only).
$ rebar3 ct
