A small spider, useful for checking a site for 404s and 500s. Patu requires httplib2 and lxml:
pip install -U httplib2 lxml
Is it safe?
To see available options:
patu.py --help
To spider an entire site using 5 workers, only showing errors:
patu.py --spiders=5 www.example.com
To spider, stopping after the first level of links:
patu.py --depth=1 www.example.com
To get a list of every linked page on a site:
patu.py --generate www.example.com > urls.txt
Instead of spidering for URLs, use a file instead and show all responses:
patu.py --input=urls.txt --verbose www.example.com
The output produced by --generate is formatted like so:
FIRST_URL<TAB>None
LINK1<TAB>REFERER
LINK2<TAB>REFERER
--input can take a file of that format, or one URL per line with no referer. --input=- reads from stdin.
Patu uses Nose for testing. To install Nose and test:
pip install -U nose
nosetests
