Objective

• I couldn’t find a script editor that recognizes the Nessus .audit file keywords and syntax so I’m working on a user defined language definition file for Notepad++.

Solution

The language definition file is still in development but you can download the current version down below.
The current version recognizes most of the keyword used in the following auditfiles:

• Windows
  
• Linux
  
• Network devices
  
• VMware
  
• Cloud
  
• Databases
  
• Storage

Importing

Importing the file into Notepad++ works like this:

Extract the rar file
Language -> Define your language... -> Import... -> select the xml file -> 
OK on import successful message
Restart Notepad++
