rebar自定义template

在开发过程中rebar自带模板建立项目,或多或少不能满足自己的开发需求。本人又是那种懒人,所以就要想办法偷懒。查看了priv模板 打造适合自己的项目模板。下面我简单的介绍整个模板的打造过程。

准备过程

 1.创建对应的template 目录

 2.ctrl+h 查看当前用户目录下是否有一个 .rebar 的文件目录 或者 shell 查看 

thinkpad@thinkpad:~$ ll -ps | grep .rebar

   4 drwxr-xr-x 10 thinkpad thinkpad    4096  6月 24 22:18 rebar/

   4 drwxrwxr-x  3 thinkpad thinkpad    4096  6月 24 22:22 .rebar/

  文中 . rebar 就是rebar 存放自定义template 文件的地方

 3 .在.reabr 文件中有一个template的文件夹,如果没有没有请创建一个

 4.进入template文件夹中创建一个 simple_game 文件夹 和一个simple_game.template的文件

 到此为止,创建rebar tempalte 的准备工作我们就做完了。

模板文功能

  1.创建一个完成的otp项目

  2.开发启动,调试脚本

  3.代码更新,编译后自动重新加载。方便调试 这也是erlang热更新的一个特性

  4.发布项目,打包镜像

 3.模板的主要制作过程是替换对已文件我恩需要替换的参数。

  在rebar文件模板中我们可以看到 这一行 {variables, [{projectid, "myproj"}]}. projectid 就是在rebar中我们传入的参数。在准备好的文件中 我们需要替换或者插入我们参数的地方 使用 {{projectid}} rebar 就会给予替换为我们传入的参数。

 4. 模板文件说明  

 app.config           整个系统启动配置参数,可覆盖app.src 参数

 erl.script  erlang 发布后启动脚本

game_app.erl      application

game.app.src       app.src

game.erl               调试启动文件 不用每次 application:start(game).

game_server.erl  server

game_sup.erl       sup

 gitignore
