如果您正在Windows上开发，使用CoffeeScript与Django最好的方式是什么？ [英] What's the best way to use CoffeeScript with Django if you're developing on Windows?

问题描述

开始使用Sass / Compass与Django 不能更容易，无论平台如何，它已经进行了一些搜索，以找到在Windows开发框上使用具有Django的CoffeeScript的最佳方式。

While starting to use Sass / Compass with Django couldn't be much easier regardless of platform, it has taken a bit of searching around to find the best way to use CoffeeScript with Django on a Windows development box.

推荐答案

自从我发布了我的原始答案（我将出于历史目的）之后，Windows上的节点支持已经大大提高，所以现在更容易得到这个工作。

Node support on Windows has greatly improved since I posted my original answer (which I will leave for historical purposes), so now it's much easier to get this working.

1. 下载并使用Windows安装Node安装程序。您将自动添加到您的Windows PATH（cmd.exe）中的节点和 npm 命令。

1. Download and install Node using the Windows installer. You get node and npm commands added to your Windows PATH automatically (available in cmd.exe).

安装CoffeeScript： npm install -g coffee-script 。然后只是测试，使用cmd.exe ...

Install CoffeeScript: npm install -g coffee-script. Then just to test, using cmd.exe...

coffee --version
CoffeeScript version 1.4.0 #sweet!

安装django-compression： pip install django-compression 。

Install django-compressor: pip install django-compressor.

添加到您的settings.py，以便django-compression将预编译您的CoffeeScript。

Add to your settings.py so django-compressor will precompile your CoffeeScript.

COMPRESS_PRECOMPILERS = (
    ('text/coffeescript', 'coffee --compile --stdio'),
)

利润！现在在Django模板中使用* .coffee文件或内联CoffeeScript，并将其自动编译为javascript并将其他脚本与其他脚本组合成一个压缩文件。

Profit! Now use *.coffee files or inline CoffeeScript in Django templates and have it automatically compiled to javascript and combined with your other scripts into a single compressed file.

示例（取自 django-compressor docs ）：

{% load compress %}

{% compress js %}
<script type="text/coffeescript" charset="utf-8" src="/static/js/awesome.coffee" />
<script type="text/coffeescript" charset="utf-8">
  # Functions:
  square = (x) -> x * x
</script>
{% endcompress %}

原始答案（已过时）：

目标是能够在Django模板中编写CoffeeScript，并将其自动转换为Javascript（以及.coffee文件）。 django-compression 有一个预编译器，在文件压缩之前，这是最好的。

The goal is to be able to write CoffeeScript right inside Django templates and have it get automatically converted to Javascript (along with .coffee files). django-compressor has a precompiler that does this, prior to the file compression it's known best for.

当然，您想要使用Windows（您怎么了？），而且预编译器假定您有典型的Linux安装node.js和coffee-脚本，能够使用其所有标准选项从命令行调用咖啡。要获得相同的功能Windows（不使用cygwin），您只需要制作一个.bat文件：

Of course the issue is you want to use Windows (what's wrong with you?), and the precompiler assumes you have a typical Linux installation of node.js and coffee-script, able to invoke 'coffee' from the command line with all its standard options. To get the same functionality Windows (without resorting to cygwin), you just have to make a little .bat file:

1. 抓取节点的最新Windows二进制

在Windows系统环境变量中将包含node.exe的路径添加到PATH

Add the path containing node.exe to PATH in Windows system environment variables

选择以下之一：

1. 鉴于npm不适用于Windows ，您可以使用最小的Python节点包管理器 ryppi 来安装咖啡脚本包。将ryppi.py放在Python脚本文件夹中。

1. Given that npm is not available for Windows, you can use ryppi, a minimal Python node package manager, to install the coffee-script package. Put ryppi.py in your Python scripts folder.

cd /d C:\Users\<USERNAME>\  #'node_modules' folder can live here or wherever
ryppi.py install coffee-script

只需下载脚本

添加路径\to\coffeescript\ bin（包含蛋糕和咖啡）到Windows系统环境变量中的PATH

Add the path\to\coffeescript\bin (containing 'cake' and 'coffee') to your PATH in Windows system environment variables

创建批处理文件可以使用命令行中的咖啡（信用为此）通过在上面的path\to-\coffeescript\bin文件夹中创建一个coffee.bat文件，其内容如下：

Make a batch file so you can use 'coffee' from the command line (credit for this) by creating a coffee.bat file in path\to\coffeescript\bin folder above, with this as its contents:

@pushd .
@cd /d %~dp0
@node coffee %*
@popd

没有这个，你必须做'node \path\to\bin\coffee'而不是'咖啡'。

Without this you have to do 'node \path\to\bin\coffee' instead of just 'coffee'.

尝试重新打开cmd.exe并键入...

Try reopening cmd.exe and type...

coffee --version
CoffeeScript version 1.1.2  #sweet!

现在您正在节点上使用真正的咖啡脚本程序。

Now you're using the real coffee-script program on node.

将django-compress预编译器设置为使用coffee.bat：

Setup the django-compressor precompiler to use coffee.bat:

COMPRESS_PRECOMPILERS = (
    ('text/coffeescript', 'coffee.bat --compile --stdio'),
)

我把它放在我的local_settings.py文件中。在Linux生产服务器或开发框使用的设置文件中，像往常一样放开.bat。如果没有.bat，Windows不开心。

I put that in my local_settings.py file. Just leave off the .bat as usual in the settings file used by your Linux production server or development box. Windows wasn't happy without the .bat.

利润！

现在，您可以在Django模板中使用内联CoffeeScript，并将其自动编译为javascript，并将其与所有其他脚本组合到单个压缩的.js文件中。我将在文档中留下使用django-compression的详细信息。

Now you can use inline CoffeeScript in your Django templates, and have it automatically compiled to javascript and combined with all your other scripts into a single compressed .js file. I'll leave details of using django-compressor to it's documentation.
