I am using this gem. When I use the following syntax, it works fine:
every :day do
rake 'billing:daily'
end
However, when I use the following syntax, the gem is giving me syntax error:
every :day { rake 'billing:daily' }
Output:
~/.rbenv/versions/2.4.3/lib/ruby/gems/2.4.0/gems/whenever-0.10.0/lib/whenever/job_list.rb:25:in `instance_eval': config/schedule.rb:26: syntax error, unexpected '{', expecting end-of-input (SyntaxError)
every :day { rake 'billing:daily' }

Aren't both the same thing? Why is the former working but not the latter?
It's a parsing/precedence issue. Braces try to bind to the nearest token, which is :day
in this case, but you want it to bind to every()
. You have to write every(:day) { rake 'billing:daily' }
to explicitly bind it to the correct token.
