get-tapas

Downloads Ruby Tapas screencast videos for paid "Ravenous" and "Legacy" subscribers.

Prerequisites:

• ruby (of course)
• curl (install with your package manager such as brew, yum, or apt-get)

Instructions:

gem install get-tapas
# Get the video download HTML text (see below.)
get-tapas [options]

This gem provides a script that partially automates the process of downloading Ruby Tapas screencasts en masse, eliminating the need to click each screencast's link individually.

Here are the steps you will need to follow:

• Log in to https://www.rubytapas.com.
• Navigate to https://www.rubytapas.com/download-list, either by inserting the URL above into the address bar, or by selecting Video Downloads from the Episodes menu.
• View the page's source, in many browsers by pressing Ctrl/Cmd-U.
• Select all its text (Ctrl/Cmd-A).
• Copy that text to the clipboard (Ctrl/Cmd-C).
• You can either:
  • pipe the text from your clipboard into the get-tapas script using pbpaste or whatever other clipboard paste command your system provides, and specifying to the script that it should get the HTML from standard input (-i -), or
  • save the text to a file, as in pbpaste > download_list.html, and specify that filename with -i path/to/download_list.html.

Running the script without any arguments will output the command line options. They're pretty self explanatory. For your convenience, here is the output:

Usage: get-tapas [options]
    -d, --data_dir dir               Directory for downloaded files (default: .)
    -i, --input_spec spec            Filespec (or '-' for STDIN) containing Ruby Tapas download list page HTML
    -0, --min_episode_num number     Minimum episode number to download
    -9, --max_episode_num number     Maximum episode number to download
    -n, --[no-]no_op                 Don't download anything, just show what would have been downloaded.
    -r, --[no-]reverse               Reverse the list of input files to download most recent first
    -z, --sleep_interval seconds     Sleep this many seconds between files
    -h, --help                       Show this message

For your convenience, the output directory defaults to $HOME/ruby-tapas.

The script makes only a crude test to see that the file has been successfully downloaded (see Downloader#validate_downloaded_file). You may want to verify that yourself. If you find an error condition not already tested, please let me know (directly or by posting an issue) and I may be able to add a test for it.
