Uninitialised Constant Files <NameError>

Ruby
1

Hi all,

I was trying a simple Ruby program using flat files ,but at certain
point in a program which says:
if Sub==“DATE” :array_sentence=Files.readlines(“date.txt”)

in program I was thrown with the error:

Uninitialised Constant Files

It would be great if somebody could guide me with this error.

Thank you in advance

Try Files without ‘s’.

if Sub==“DATE” :array_sentence=File.readlines(“date.txt”)

Identifiers which start with a capital letter are constants.

The error says that there is no constant in your program called “Files”.
Unless you have defined one, this is correct.

However there is a constant (class) in the standard library called
“File”.

…but then you’re left with trying to assign to a symbol.

Yep, I suspect he (kind of) wants

if sub==“DATE” : array_sentence=File.readlines(“date.txt”) end

Now I don’t think that this form of if is particularly attractive, and
Ruby 1.9 has done away with using : for then.

I’d rewrite this using the if modifier:

array_sentence=File.readlines(“date.txt”) if sub==“DATE”
