Regexp+hash problem

Hello !

I becoming totally mad about this simple script, whose goal is to
capture various information (written in a single file) about some chess
games : the conversion I need for the month seems to be the problem : I
am using a hash to convert “Feb” into 2,etc. But, this works only for
the first line of my file !?

The error reported is “can’t convert String into Integer (TypeError)”,
but I can’t figure what it means.

Can someone help ?
Thx
JC

Why don’t use Date.strptime to match the date info ?

So, I would guess that you didn’t actually post the code that produced
that error message. When I run the code you posted, this is the output:

Hello Jean-Christophe,

I think this is due to the fact that you have sometimes one, sometimes
two spaces in your data file between (B or W) and what follows and that
you only allow one space in between the brackets in your regexp.
Maybe it would be a good idea to set some default value for the Hash
for undefined keys so that you notice when the Regexp didn’t match …

months=Hash.new(“missing”) # default value of months is “missing”

Best regards,

Axel

Or leave the hard work to Date.parse:

require ‘date’
DATA.each do |line|
d = Date.parse(line)
puts “#{d.day} #{d.month} #{d.year}”
end
#=>

12 1 2008

17 2 2008

17 7 2008

17 3 2008

29 2 2008

Just FYI, this is effectively the same as…

require ‘date’
h = {}
Date::ABBR_MONTHNAMES.each_with_index {|obj, idx| h[obj] = idx}
h[“Feb”]

…but I would tend to just use the array since the set is so small…

mons = Date::ABBR_MONTHNAMES
mons.index(“Feb”)

           puts "\nprocessing line #{lineNumber}\n"
                       month = h[m] # <<==  can't convert String into

Integer (TypeError) on the second line of the file
puts “#{m} corresponds to month #{month}”

           puts num,score,m,date,hour,minu,year

           #dateTime  = DateTime.new(y=year,m=2, d=date, h=hour,

min=minu, s=0) end
end
end

There is something else going on here, because your code, as written,
works fine for me as long as the data file is clean and I change your
regexp so as to account for extra whitespace (like in line nums 21:
and 22: – this doesn’t cause your error, it just makes you miss those
lines since res will be nil).
