Ctags Companion

A Visual Studio Code symbols provider based on Ctags. This extension provides the following capabilities:

• Go to Definition (F12)
• Go to Symbol in File (⇧⌘O) as well as the Outline
• Go to Symbol in Workspace (⌘T)

Usage

First of all, make sure you have Universal Ctags installed.

In order to provide symbol definitions a tags file must be present. You can generate it using the "rebuild ctags" task (Terminal > Run Task... and select "Ctags Companion: rebuild ctags"). It will run ctags and generate a tags file inside your project directory. The extension will then use readtags to perform symbol definition lookup.
