Print file in a beautiful way with its syntax highlighted on the Linux bash console

The Linux 'cat' program lacks the syntax recognition and highlighting features. If you want to print a file in a beautiful way with its syntax highlighted you can use our wrapper: scat. 

It is a wrapper around the source-highlight tool that automatically recognizes the syntax and prints the file on stdout. The source code is taken from the github repo of Japh Woldrich: https://github.com/trapd00r/utils

Installation

 
cd $HOME
mkdir $HOME/tools
cd $HOME/tools
wget https://raw.github.com/trapd00r/utils/master/scat
chmod a+x scat

export PATH=$PATH:~/tools

Demonstration

Beautiful code formatter for JavaScript in Sublime

I needed recently to work with some JavaScript code to understand how bookmarklets work in Google Chrome. Unfortunately the js code was often not well formatted and difficult to read.

Problem

How to automatically reformat JavaScript code so it looks beautiful and is easy to read.

Solution

I recommend this online site if you don't need to have this functionality in your editor of choice: http://jsbeautifier.org/. To enable beautiful code formatting in Sublime you can:

• Install the CodeFormatter plugin in Sublime https://sublime.wbond.net/packages/CodeFormatter
• The plugin requires node.js that can be downloaded from here http://nodejs.org/#download
• The default node.js installation doesn't provide the js-beautify module so we need to install this with the help of npm (details instructions can be found here https://npmjs.org/package/js-beautify)

Testing

To test that the node.js and the necessary plugin is installed correctly you can run the node virtual machine and try to import the module:

 
$ node
> require("js-beautify")
{ [Function]
  js: [Function: js_beautify],
  css: [Function: css_beautify],
  html: [Function],
  js_beautify: [Function: js_beautify],
  css_beautify: [Function: css_beautify],
  html_beautify: [Function] }
>

To test that the plugin is installed successfully in in sublime you can:

• check sublime tree directory

 
 ... Sublime2\Data\Packages\CodeFormatter\
 

To trigger the formatting:

• Menu tools -> Command Palette (Cmd+Shift+P or Ctrl+Shift+P) and type `Format`.
• The default keyboard shortcat is  ["ctrl+alt+f"] or 
• If you want to run the command from the console

 
 view.run_command("code_formatter")
