Snort User Defined Language (UDL) in Notepad++ ¹

I recently created a Snort “User Defined Language” in Notepad++ and wanted to share both the schema, what it looks like, and the steps necessary to create it.

To start, if not already done, you should download and install Notepad++ from here. It does not matter which package you choose so long as you remember where it is installed and/or where you placed the install folder.

Next, in order for the parser for Snort to work, we will need to install UDL2 from here. The download consists of two files (Notepad2++.exe and SciLexer2.dll) whi

Pass the GTK_THEME environment variable to the app:

$ GTK_THEME=<theme> <path>

You can replace <theme> with any available theme:

$ ls /usr/share/themes
