Gruntfile中的简单正则表达式 [英] Simple regex in Gruntfile

问题描述

我在 Gruntfile 中有以下行。

js
文件：['<％= yeoman.app％> / scripts / {，* /} *。咖啡']，


有人可以告诉我什么 {，* /} * 是什么意思？我知道它试图匹配脚本文件夹中的所有 .coffee 文件，但我想知道它是如何做到这一点的。

Could someone be so kind as tell me what {,*/}* mean? I know it's trying to match all .coffee files in the scripts folder, but I want to know how it does that.

推荐答案

在{}内部实际上有两个用逗号分隔的匹配项。一个是空白的，在逗号左边没有字符。一个是任意数量的字符和一个正斜杠。最后的*匹配.coffee扩展名前的文件名。

The {,*/} matches one or zero directories between scripts and the .coffee file. Inside the {} there are actually two matching terms separated by a comma. One is blank, represented by no characters to the left of the comma. One is any number of characters and a forward slash. The final * matches the filename before the .coffee extension.

顺便说一句，这不是正则表达式，它是通配符。

By the way, this is not regular expressions, it's globbing.
