Let’s consider we’re getting a long file through HTTP:

How to get a progress (percentage of done) of the download process? I  
didn’t find such API in Net::HTTP

You can use Net::HTTP#request\_get and Net::HTTPResponse#read\_body:

$ ruby -rnet/http  
h = Net::HTTP.new ‘[blog.segment7.net](http://blog.segment7.net)’  
h.request\_get ‘/’ do |r| r.read\_body do |s| p s.length end end  
^D  
751  
184  
1024  
184  
1024  
184  
[…]  
$

There are probably other ways without #request\_get

Cool, I also did not know that, but I wondered about this for a long  
time.

Nice to see such snippets. 🙂

You could use the “progressbar” library …

I also put a note in the margin of my book about this one. 🙂
