Examples

Grab a single page

The get command lets you retrieve the content of a web page.

papeer get https://www.eff.org/cyberspace-independence
# A Declaration of the Independence of Cyberspace
# ===============================================

# Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather...

Grab several pages (recursive mode)

The recursive option lets you extract the table of content of a website, then scrape the content of each one of its pages.

Display table of content

Before trying the recursive option, it is a good idea to use the ls option, which lets you vizualize the content that will be retrieved. You can use several options to customize the table of content extraction, such as selector, limit, offset and include. Type papeer help for more information about those options.

papeer ls https://news.ycombinator.com/ --limit=5

Scrape time

Once you are satisfied with the table of content listed by the ls command, you can actually scrape the content of those pages. You can use the same options that you specified for the ls command. In recursive mode, you also have the possibility to use delay and threads options.
