Description

I'm using Terraform templatefile function to parameterize some queries, therefore I can have SQL like:

SELECT _entity.*,
FROM `${project}.other_table`
WHERE field IS TRUE
;

And it renders like this:

I'm guessing the syntax regex might need to be tweaked for it to ignore the $ in the identifier.
