Erlang里的make

阅读更多

Erlang自带一个make工具
我们看一个例子

目录结构:

--Emakefile
-include
 --test.hrl
-src
 --test.erl
-ebin

Emakefile:

{'src/*', [{i, "include"}, {outdir, "ebin"}]}.

test.hrl:

-record(server_opts,
  {port,
   ip="127.0.0.1",
   max_connections=10}).

test.erl:

-module(test).
-include("test.hrl").

-export([start/0]).

start() ->
  Opts1 = #server_opts{port=80},
  io:format("~p~n", [Opts1#server_opts.ip]),
  io:format("~p~n", [Opts1#server_opts.port]),
  io:format("~p~n", [Opts1#server_opts.max_connections]).

使用Erlang的make:

erl -make

运行:

erl -noshell -pa ./ebin -s test start -s init stop

结果:

"127.0.0.1"
80
10
