Commands

Shows all predefined comics which can be used with the download command.

download

Downloads a predefined comic. Supports the --cbz flag, which creates a .cbz archive of the downloaded comic.

search

Searches for an XPath that can download the whole comic. Supports the --cbz flag, which creates a .cbz archive of the downloaded comic,-s, which verifies only the provided page of the comic, -y, which skips the verification prompt, and -j, which runs the javascript on pages before downloading.

custom

Downloads a user-defined comic. To download a specific comic, you'll need a link to the first page, an XPath expression giving out the link to the next page and an XPath expression giving out the link to the image. More info here. Supports the --cbz flag, which creates a .cbz archive of the downloaded comic, -s, which verifies only the provided page of the comic, and -y, which skips the verification prompt.

Examples

• webcomix download xkcd
• webcomix search xkcd --start-url=http://xkcd.com/1/
• webcomix custom --cbz (You will be prompted about other needed arguments)
• webcomix custom xkcd --start-url=http://xkcd.com/1/ --next-page-xpath="//a[@rel='next']/@href" --image-xpath="//div[@id='comic']//img/@src" --cbz (Same as before, but with all arguments declared beforehand)

Making an XPath selector

Using an HTML inspector, spot a html path to the next link's href attribute/comic image's src attribute.

e.g.: //div[@class='foo']/img/@src This will select the src attribute of the first image whose class is: foo

Note: webcomix works best on static websites, since scrapy(the framework we use to travel web pages) doesn't process Javascript.

To make sure your XPath is correct, you have to go into scrapy shell, which should be downloaded when you've installed webcomix.

scrapy shell <website> --> Use the website's url to go to it.
> response.body --> Will give you the html from the website.
> response.xpath --> Test an xpath selection. If you get [], this means your XPath expression hasn't gotten anything from the webpage.

Contribution

The procedure depends on the type of contribution:

• If you simply want to request the addition of a comic to the list of supported comics, make an issue with the label "Enhancement".
• If you want to request the addition of a feature to the system or a bug fix, make an issue with the appropriate label.

Running the tests

To run the tests, you have to use the pytest command in the webcomix folder.
