Erlang里的make

Erlang自带一个make工具
我们看一个例子

目录结构:

Java代码

1. --Emakefile  
2. -include  
3.  --test.hrl  
4. -src  
5.  --test.erl  
6. -ebin  

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

Emakefile:

Java代码

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

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

test.hrl:

Java代码

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

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

test.erl:

Java代码

1. -module(test).  
2. -include("test.hrl").  
3.   
4. -export([start/0]).  
5.   
6. start() ->  
7.   Opts1 = #server_opts{port=80},  
8.   io:format("~p~n", [Opts1#server_opts.ip]),  
9.   io:format("~p~n", [Opts1#server_opts.port]),  
10.   io:format("~p~n", [Opts1#server_opts.max_connections]).  

-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:

Java代码

1. erl -make  

erl -make

运行:

Java代码

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

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

结果:

Java代码

1. "127.0.0.1"  
2. 80  
3. 10
