在rebar发布的项目中添加监视工具

默认使用rebar创建的项目没法使用observer，可以如下操作

修改app.src

{application, tcp_server,
    [
        {description, ""},
        {vsn, "0.1"},
        {registered, []},
        {applications, [
            debugger,
            observer,
            kernel,
            stdlib
        ]},
        {mod, { tcp_server_app, []}},
        {env, [
            {listen_port,}
        ]}
    ]}.

或者是rel目录的reltool.config

{sys, [
       {lib_dirs, ["../apps", "../deps"]},
       {erts, [{mod_cond, derived}, {app_file, strip}]},
       {app_file, strip},
       {rel, "tcp_server", "0.1",
        [
         kernel,
         stdlib,
         sasl,
         tcp_server
        ]},
       {rel, "start_clean", "",
        [
         kernel,
         stdlib
        ]},
       {boot_rel, "tcp_server"},
       {profile, embedded},
       {incl_cond, derived},
       {excl_archive_filters, [".*"]}, %% Do not archive built libs
       {excl_sys_filters, ["^bin/(?!start_clean.boot)",
                           "^erts.*/bin/(dialyzer|typer)",
                           "^erts.*/(doc|info|include|lib|man|src)"]},
       {excl_app_filters, ["\.gitignore"]},
       {app, tcp_server, [{mod_cond, app}, {incl_cond, include}]}
      ]}.

rebar generate以后，直接生成

具体模块名字可以用reltool:start().查看
