How to create simple coffescript example without rails

I am new to coffeescript. I saw a coffeescript video in Rails casts.com. From that episode I understand how to convert the normal Js and Jquery to coffeescript code and the usage of coffeescript.

I am trying to create a coffeescript example without rails. I wetn through the coffeescript site. They first install Node.js. I tried to install node.js in windows and ubuntu, but I had failures. I followed the instruction as per this site:

http://howtonode.org/how-to-install-nodejs#ubuntu

For ubuntu I got "bash: ./configure?: No such file or directory" error when I execute the following command

./configure

Can anyone help me to create simple coffescript example without rails?

One more thing - In Mac "By the help of homebrew I can see the compiled js of coffescript code through compiled and Display Js window". Are there any options available in windows and ubuntu?

Ubuntu 11.10 has an up-to-date package for CoffeeScript.

sudo apt-get install coffeescript

I would bet the easiest way to install Node.js on Ubuntu is through APT:

$ sudo apt-get install nodejs

It probably will get some outdated version but it can be enough for some tests.

If you prefer the latest version (which is a reasonable preference), I bet it would be easier to install Node.js from the dist package. Just copy and paste this on terminal:

wget http://nodejs.org/dist/node-v0.5.0.tar.gz && \
tar zvxf node-v0.5.0.tar.gz && \
cd node-v0.5.0 && \
./configure && \
make && \
sudo make install

This line will:

  • download the latest Node.js source code with wget http://nodejs.org/dist/node-v0.5.0.tar.gz
  • uncompress the downloaded source code with tar zvxf node-v0.5.0.tar.gz
  • enter into the source code with cd node-v0.5.0
  • set the build parameters with ./configure
  • effectively build the Node.js executable with make
  • install the built Node.js in your path with sudo make install

The && means "execute the next command if the previous command succeeds" (for example wget http://nodejs.org/dist/node-v0.5.0.tar.gz && tar zvxf node-v0.5.0.tar.gz means that we will download the package with wget and iff the download succeeds we will unpack the download file with tar. The backslashes (\) are here for allowing us to break all the series of commands in more than one line because, by default, we would have a big line:

wget http://nodejs.org/dist/node-v0.5.0.tar.gz && tar zvxf node-v0.5.0.tar.gz && cd node-v0.5.0 && ./configure && make &&  sudo make install

Then, you can install npm with this simple command, found in the own npm github page:

$ curl http://npmjs.org/install.sh | sudo sh

With npm, it will be too easy to install coffee, as you can see in the CoffeeScript page:

$ npm install coffee-script

Now, just run your tests:

$ coffee
coffee> a = key: 'value'
{ key: 'value' }
coffee> a.key
'value'

Does it look like to much work? You can try CoffeeScript in the language page. Just click in "Try CoffeeScript" and a console will appear to you.

For testing and demo purposes it may be sufficient to have your CoffeeScript compiled directly in browser. You can include the CoffeeScript compiler and your code in a tag.

This method is not efficient though so please use it for playing around.

Please see this section on how to set things up:

"text/coffeescript" Script Tags

Good luck!
