View source for User:Aeric/HowTo:Install CoffeeScript

:1. Go to http://nodejs.org/, click [Download], do the install
:: --CoffeeScript requires Node.js to run the compiler 
::   --It uses npm (node package manager) to download & install coffescript
::     (bundled with Node.js!)

:2. In File Explorer, move the nodejs folder to C:\ 
::    --In :\Program Files, or C:\Program Files (x86) on a 64 bit system  
   
:3. Start a command shell
::cd c:\nodejs
::set path=%PATH%;%CD%
::setx path "%PATH%   
:::   --that command modifies the registry, so you don't have to go find env variables!

:4. Install Coffeescript
::npm install -g coffee-script
:::  --installation folder is created:
:::    C:\Users\{user}\AppData\Roaming\npm\node_modules\coffee-script

:5. Start a new shell,so the commands in coffee-script/bin can be used

:6. In the command shell, verify the install:
::coffee
:::  --after a short pause, you see the prompt for the coffe-script interpreter
:::  --coffee>
::  --Press Ctrl+C to exit the interpreter
::  --Try out the "instant eval" option for a one-line command:
:::      coffee -e "console.log num for num in [10..1]"
:::      result: Count down from 10 to 1, one value per line

:7. Do a test compile
::   --Create a project folder
::   --Create a file with the initial sample code from coffeescript.org (below)
:::   (sample.coffee)
::   --Compile it: coffee -c 
::   --Resulting .js file should match the results displayed at coffeescript.org
::   --Notice how much cleaner and nicer it is, and much more fun it will be to work with!

:8. Clean up the build environment
::   --create src/ and lib/ subfolders
::   --move the .coffee file to src/
::   --nuke the .js file
::   --Save and run the following command (put it build.cmd):
:::        coffee -c -o lib/ src/

:9. Other options to explore:
::      --watch a file and recompile every time it is saved
:::           coffee -w -c myfile.coffee
::      --concatenate a list of files into a single script
:::           coffee --join project.js --compile src/*.coffee
::      --watch and recompile an entire project
:::           coffee -o lib/ -cw src
