Yeoman 生成器可以更新现有文件吗? [英] Can Yeoman generators update existing files?

问题描述

所以只是为了给你一些上下文，我正在尝试创建一个生成器来创建一些文件(当然基于用户输入)以及更新项目中的一些现有文件(比如添加一条新路线).

So just to give you some context, I'm trying to create a generator that will create some files (based on user input of course) as well as update some existing files in the project (like adding a new route for example).

使用 this.template 创建文件没问题...问题是:有没有办法用 Yeoman 做到这一点，而不必使用 Node 读取文件并做一些奇特的查找和替换?

Creating the files using this.template is no problem... the question is: is there any way to do this with Yeoman without having to read the file using Node and doing some fanciful find and replace?

推荐答案

好的，我找到了问题的答案.

Ok, so I found the answer to my question.

Addy Osmani 向我展示了在哪里可以查看 推特上的这个帖子，后来我找到了此链接 这正是我需要的.

Addy Osmani showed me where to look in this thread on twitter, and then I later found this link which shows exactly what I need.

它的要点归结为两个函数:readFileAsString 和 write.用法如下:

The gist of it boils down to two functions : readFileAsString and write. Usage is as follows:

var path = "/path/to/file.html",
    file = this.readFileAsString(path);

/* make modifications to the file string here */

this.write(path, file);

我也写了关于这个的博客 在我的博客上.

I've also blogged about this on my blog.

正如 Toilal 在评论中提到的:

As mentionned in comments by Toilal :

write 方法已不存在，必须替换为 writeFileFromString(参数也颠倒)- Toilal

The write method doesn't exists anymore, and must be replaced by writeFileFromString (arguments are also reversed) – Toilal

然后，正如 ivoba 在评论中提到的:

EDIT 2

And then, as mentionned in comments by ivoba:

this.writeFileFromString &this.readFileAsString 已弃用，现在应该使用 github.com/yeoman/html-wiring，情况有所改变 :) – ivoba

this.writeFileFromString & this.readFileAsString are deprecated, github.com/yeoman/html-wiring should be used by now, things change :) – ivoba
