I am trying to figure out how to split a string into chunks of 25  
lines or less to pass to another function

Any ideas on how I could approach this?

thanks,

Luis

string.scan(/(?:.\*?\n){1,25}/)

I think you can get with this:

def split\_newlines(str, num\_lines)  
result,prev,index = 0,0,0  
array = []

until result.nil?  
result = str.index(“\n”, result)  
unless result.nil?  
index += 1  
array \<\< str[prev…result] if index%num\_lines==0  
result += 1  
end  
prev = result if index%num\_lines==0 and result  
end  
array \<\< str[prev…str.size] unless prev == str.size  
end

But it seems too complicated for me.  
I’m sure there is a very better approach but I’m not an experienced ruby  
programmer. I like very much to see better responses for learn  
something.
