用Makefile执行的Python脚本 [英] Python Script Executed with Makefile

问题描述

我正在编写python脚本，并在Makefile中执行它们.python脚本用于处理管道中的数据.我希望Makefile每次更改python脚本时都执行脚本.

I am writing python scripts and execute them in a Makefile. The python script is used to process data in a pipeline. I would like Makefile to execute the script every time I make a change to my python scripts.

有人知道怎么做吗?

推荐答案

信息不多，所以这个答案有点含糊.Makefile的基本原理是列出每个目标的依赖性.在这种情况下，您的目标(我们将其称为foo)取决于您的python脚本(我们将其称为do-foo.py):

That's not a lot of information, so this answer is a bit vague. The basic principle of Makefiles is to list dependencies for each target; in this case, your target (let's call it foo) depends on your python script (let's call it do-foo.py):

foo: do-foo.py
    python do-foo.py > foo

现在，只要do-foo.py发生更改，foo就会重新运行(当然，前提是您要调用make).

Now foo will be rerun whenever do-foo.py changes (provided, of course, you call make).
