Add --start parameter

[lubien]

Works for both oldest and latest runnings ;)

Hi, thank you so much for this!

I just unbroke the build in master, so if you rebase, the tests should pass.

Some thoughts – let me know what you think.

• I wonder if something like --start-from or --start-from-episode might be clearer than --start.
• The README text might be clearer if it was more specific and had an actual example, something like:

You may want to start downloading from a given episode number, like:

     ./sipper --user me@example.com --pw mypassword --oldest-first --start-from-episode 50

• Using String.contains? to find the given episode seems like it could be fragile. As a fictitious example, what if you wanted to start from episode "100" but episode 30 was titled "030 - accepting 1000 connections". We would then stop at episode 30. Could we be a bit more specific in our string matching?

If you feel like it, a test would be really nice, but I've been lax about it elsewhere in this project, so I don't consider it a must at this point :)

Sorry for delaying my answer.

Indeed --start-from-episode seems better.

About the docs, you may be the most fit one to do so can you do it? hehe

How about using:

%{"episode" => episode} = Regex.named_captures(~r/^(?<episode>\d{3})/, "123_foo_bar")

[henrik]

Sure, happy to fix the docs :) I can do that after merging.

Yeah, anchoring the regex to the beginning of line like that seems like a good idea. Go for it!

About the tests I'm not sure how I'm going to test the runner with Auth and stuff :x
