How can i match this with ruby regex {{article | image}}

Question

It also needs to work for {{ article |image}} or any other withespace combination inside the double braces.

Answer 1

Need a lot more information about exactly what you need and the type of data you are searching.

{{.*}}

This will work for both examples.

{{\s*\w+\s*\|\s*\w+\s*}}

Is much more specific.

Answer 2

This will match all your {{ }} content:

{{([^}]*)}}
