Question

are there different sensitivities/settings to whitespace in ruby?

i have a RoR project, where an active record call has a lot of components:

    max_stuff = FooSummary.select("max(stuff) as stuff")
                        .joins(:foo => :bar)
                        .where("user_id = ? and record_date < ?", r.user_id, r.record_date)
                        .group("user_id")
                        .first

1.9.3 works fine with this on my mac, but on the ubuntu server it runs on, it complains about the fact that .joins is on a separate line (unexpected . expecting kEND)

what gives?

Answer 1

Move the period to the preceding line. If parsing line-by-line,

foo = bar

looks like a full statement, and the next line, taken separately, is a syntax error:

.baz

However, this can’t be a statement:

foo = bar.

and the parser knows it has to append the next line as well:

baz

(which gives the same parse as foo = bar.baz, as expected).
