安装

可以从python包索引（pypi）或 来源。

使用pip

$ pip install exr-builder

使用简易安装

$ easy_install exr-builder

示例

构建脚本是用纯python编写的，exr builder负责 管理任务之间的任何依赖关系并生成命令行 接口。

编写构建任务非常简单，您只需要知道@task 装饰工。任务只是用 @task()装饰器。依赖项也用@task()指定。 可以使用@task(ignore=True)忽略任务。禁用任务 是一个有用的特性，可以在您有一个任务 许多其他任务都依赖于，您希望快速将其从 所有依赖任务的依赖链。

运行exr生成器任务

命令行界面和帮助将自动生成。任务 描述是从函数docstrings中提取的。

$ exrb -h
usage: exrb [-h][-l][-v][-f file][task [task ...]]

positional arguments:
  task                  perform specified task and all its dependencies

optional arguments:
  -h, --help            show this help message and exit
  -l, --list-tasks      List the tasks
  -v, --version         Display the version information
  -f file, --file file  Build file to read the tasks from. Default is
                        'build.py'

$ exrb -l
Tasks in build file ./build.py:
  clean                       Clean build directory.
  copy_file
  echo
  html                        Generate HTML.
  images           [Ignored]  Prepare images.
  start_server     [Default]  Start the server
  stop_server

exr生成器负责处理任务之间的依赖关系。在下面 case start_服务器依赖于clean、html和图像生成（图像 任务被忽略）。

$ exrb #Runs the default task start_server. It does exactly what "exrb start_server" would do.
[ example.py - Starting task "clean"]
Cleaning build directory...
[ example.py - Completed task "clean"][ example.py - Starting task "html"]
Generating HTML in directory "."[ example.py - Completed task "html"][ example.py - Ignoring task "images"][ example.py - Starting task "start_server"]
Starting server at localhost:80
[ example.py - Completed task "start_server"]

任务名称的前几个字符足以执行任务， 只要部分名称是明确的。可以指定多个 要在命令行中运行的任务。再次获取依赖项 关心。

$ exrb cle ht cl
[ example.py - Starting task "clean"]
Cleaning build directory...
[ example.py - Completed task "clean"][ example.py - Starting task "html"]
Generating HTML in directory "."[ example.py - Completed task "html"][ example.py - Starting task "clean"]
Cleaning build directory...
[ example.py - Completed task "clean"]

“html”任务依赖项“clean”只运行一次。但是干净可以 稍后再显式运行。

exrb任务可以从命令行接受参数。

$ exrb "copy_file[/path/to/foo, path_to_bar]"[ example.py - Starting task "clean"]
Cleaning build directory...
[ example.py - Completed task "clean"][ example.py - Starting task "copy_file"]
Copying from /path/to/foo to path_to_bar
[ example.py - Completed task "copy_file"]

exrb还可以接受关键字参数。

$ exrb start[port=8888][ example.py - Starting task "clean"]
Cleaning build directory...
[ example.py - Completed task "clean"][ example.py - Starting task "html"]
Generating HTML in directory "."[ example.py - Completed task "html"][ example.py - Ignoring task "images"][ example.py - Starting task "start_server"]
Starting server at localhost:8888
[ example.py - Completed task "start_server"]

$ exrb echo[hello,world,foo=bar,blah=123][ example.py - Starting task "echo"]('hello', 'world'){'blah': '123', 'foo': 'bar'}[ example.py - Completed task "echo"]

组织生成脚本

您可以将构建文件分解为模块并简单地导入它们 在主生成文件中。
