rubyists-
any idea why this:
year, month, day = [‘year’,‘month’,‘day’].map{|k| cgi[k]}
should yeild different results than this:
year, month, day = %w(year month day).map{|k| cgi[k]}
this first case, with identical form data, results in expected behavior, the
second results in all values being nil.

%w{year month day} and %w(year month day) are the same thing, you can use
even %w%year month day% if you want.

No idea. Could you show us problem reproducing code snippet?

I didn’t know that. Ruby rocks.
But in that case, I can’t imagine what the problem with this code could
be.

Your script has “%(year month day)” instead of “%w(year month day)”. I
presume ‘w’ was somehow swallowed when rendering to html, and it IS actually
present in the script you test. Is it?

By the way, I just verified in IRB that %(year month day) is actually “year
month day”. It is quite surprising to me.

I can’t imagine either. It must be the same.
ahoward, are you testing these 2 constructs in exactly same spot in the
code, or they are in different places? Is there a chance that something else
breaks in? Are you absolutely sure that the input is exactly the same in
both cases? What happens if you mock cgi and provide known values before the
statement?
Gennady.

“year
month day”. It is quite surprising to me.
A pleasant surprise, right?
This is Ruby’s generalized string. You
can say things like:
%(He said, “She told me, ‘Hello.’”)
instead of escaping the usual quote characters.
In fact, the parens are not even required.
And I think if you use a non-doubled character
like -, you can open and close with the same
character:
%-He said, “She told me, ‘Hello.’”-
I’m saying this from memory. I’ll
be embarrassed if I am wrong.
