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
