# Examples
|
||||
## Scrape a whole website
|
||||
|
||||
## Grab a single page
|
||||
If a navigation menu is present on a website, you can scrape the content of each page.
|
||||
|
||||
The `get` command lets you retrieve the content of a web page.
|
||||
You can activate this mode by using the `depth` or `selector` options.
|
||||
|
||||
### `depth` option
|
||||
|
||||
This option defaults to 0, `papeer` will grab only the main page.
|
||||
|
||||
If you specify a value greater than 0, `papeer` will grab pages as deep as the value you specify.
|
||||
|
||||
> Using `include` option will include all intermediary levels into the book.
|
||||
|
||||
### `selector` option
|
||||
|
||||
If this option is not specified, `papeer` will grab only the one page.
|
||||
|
||||
If this option is specified, `papeer` will select the links (a HTML tag) present on the main page, then grab each one of them.
|
||||
|
||||
You can chain this option to grab several level of pages with diferent selectors for each level.
|
||||
|
||||
### Display the table of contents
|
||||
|
||||
Before actually scraping a whole website, it is a good idea to use the `list` command. This command is like a **dry run**, which lets you vizualize the content before actually retrieving it. You can use several options to customize the table of contents extraction, such as `selector`, `limit`, `offset`, `reverse` and `include`. Type `papeer list --help` for more information about those options.
|
||||
|
||||
```sh
|
||||
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...
|
||||
papeer list https://12factor.net/ -s 'section.concrete>article>h2>a'
|
||||
```
|
||||
|
||||
## 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.

### 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.
