Overview

Checks that your heredocs are using the configured case. By default it is configured to enforce uppercase heredocs.

Examples:

EnforcedStyle: uppercase (default)

# bad
<<-sql
  SELECT * FROM foo
sql

# good
<<-SQL
  SELECT * FROM foo
SQL

EnforcedStyle: lowercase

# bad
<<-SQL
  SELECT * FROM foo
SQL

# good
<<-sql
  SELECT * FROM foo
sql
