somewhat new to ruby, and im trying to write a simple program to print
[IMG] tags for php forums on my screen so I dont have to copy and paste
100 of them and change the pictures number every time. Example I have
127 pictures from a race that I would like to post, the tag is
[img]http://www.empiremotoring.org/pictures/pp.5.17.08/IM...[/img]
and I would like the program to list the next one as
[img]http://www.empiremotoring.org/pictures/pp.5.17.08/IM...[/img]
[img]http://www.empiremotoring.org/pictures/pp.5.17.08/IM...[/img]

and so on, this is what I have so far, I am just having trouble getting
it add +1 to the end ever time because it dosent like numbers in the
string, I have tried several things but non of which worked out. Any
advice would be a great help here is the code

# Img forum tag lister

puts "What is your url: " # url from input
url = gets.chomp

puts "What is your files name: " # file name from input (IMG_ for canon
DSC_ for sony etc.)
file = gets.chomp

puts "How many files: " # # of files wanted to print from input
num = gets.to_i

puts "beginning file #: " # beginning number extension, ( number at end
of picture file eg IMG_0987, would be 0987)

bnum = gets.chomp

print ("[img]" + url + file + bnum.to_s +=1 + ".jpg [/img]") *num.to_i #
prints IMG tag.

I realize that you can put the numbers into a sting without first
converting but the how would you go about having it add +1 after it has
been converted?

Thanks, --Miles

try this:

num.times { puts "[img]#{url}#{file}#{bnum=bnum.succ}.jpg[/img]" }

Hi Miles,

you can use the pound sign :

res='5'
p "The answer is #{res=res.succ}"
p res

res=5
p "The answer is #{res=res.succ}"
p res

... but, be careful for "negative number-strings" ...

Best regards,

Axel

Or you could use a regexp on the string to separate out the number, then
increment it, and put the string back together again.

But this is a Ruby Nooby here, fresh from Perl and still finding out how
to do things the proper Ruby way. ;-)
