Using Live Templates in TODO Comments
On this page:
Let's explore an advanced RubyMine's facility to create a live template for the TODO items' text. Why do we need it at all? For example, you want your team mates to create unified TODO items, with the user name automatically filled in, followed by some arbitrary text.
This is how it's done.
Creating TODO pattern and filter
Open the Settings/Preferences dialog, and under the Editor section, click TODO.
