Sublime Text 2/3 Syntax Definitition for Cisco [router/]switch[/firewall] configurations. This package will highlight Cisco/ HPE Aruba configuration and commands within Sublime Text 2/3.
Using Package Control: If you have package control installed then installing this is a snap. Simply open the command palette (Tools->Command Palette). Then type "install" then search for this plugin by typing "Cisco/ HPE Aruba Syntax Highlighter". That's it. It should be installed.
Without Git: Download the zip from github, and extract the files to your Sublime Text "Packages" directory, into a new directory named Cisco-HPE-Aruba. You can find the packages directy by going to Preferences -> Browse packages, within Sublime Text 2/3.
With Git: Clone the repository in your Sublime Text "Packages" directory:
git clone git://github.com/LaurentFough/sublime-cisco-hpe-aruba-syntax.git
Once installed navigate to View->Syntax->Cisco to apply the Cisco syntax to the document.
This syntax definition will automatically be applied to .txt files and .cfg files.
Using control-/ will comment out any line that is highlighted.
Once Cisco syntax is turned on you can then try different color schemes by going to Preferences -> Color Schemes.
If you wish to customize this even further for your own needs navigate to the Cisco package (Preferences -> Browse Packages). Edit the Cisco Definitions.json-tmlanguage file within Sublime Text 2. Install AAAPackageDev. After your changes go to Tools -> Build, to rebuild the syntax definitions.
