Opening an IO stream or a file ?

[housekeeper]

Hi,

In CSV we have the facility to open an IO stream or a file

# raw data could also be an uploaded file 
# which remains in memory
raw_data = File.open(file).read 
csv_data = CSV.new(raw_data)

or

CSV.open(file)
# etc etc

Is it possible to just give roo an IO stream if I can specify its type and parse?
I want to open excel based files without hitting the file system is this possible

Many thanks in advance.

Kind regards,
Carl

Is anyone still interested in this feature?

I would definitely be interested in something like this. Would be very handy to create a placeholder object that has the same interface as a Roo::CSV instance.

For instance, right now, I'm wanting a default instance of Roo::CSV.new(StringIO.new('')). The current code is using a default value of nil which naturally trickles up to elsewhere in the code throwing an "undefined method ... for nil:NilClass".

Being able to create, in effect, a null object that responds to the Roo::CSV interface would be helpful.

This fix doesn't work for ROO::CSV yet
