I would like to have syntax highlighting while perusing my configs - does anybody know of a good Cisco IOS syntax highlighting bundle for TextMate or Sublime Text?

Edited (2015-09-21) to add:

GitHub Atom Editor has a Cisco IOS syntax highlighter in their built in "packages" repo and it is easy to install. I think that Sublime Text is a better editor, but if you are not already invested in ST, I recommend giving Atom a look.

I haven't tried it yet but there is a GitHub repo someone made for Cisco IOS Syntax Highlighting for Sublime Text 2.

    Unfortunately, it is very limited in scope.

Though a .tmBundle exists for syntax highlighting in Cisco IOS, it is very limited in scope.

Have you made or do you know of a better bundle?


Grab Notepad++ which has many different language (formatting=parsing) options. Though I don't have a specific one for Cisco, I'm sure someone's created one or you can define your own.


You can try Network Tech if you use Sublime Text 3. I am the author.
