README.md

Diffido

Spot the difference on the web.

Tired of clicking F5 waiting for a change on a web page? Define a list of pages to watch, and receive an email when something has changed.

Install, run, develop and debug

Docker

Just run:

./run-docker.sh

Old-fashioned installation

To install it:

wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
# if you want to install these modules for an unprivileged user, add --user and remove "sudo";
# if you want to upgrade the versions already present in the system, also add --upgrade
sudo pip3 install lxml
sudo pip3 install pytz
sudo pip3 install apscheduler
sudo pip3 install requests
sudo pip3 install sqlalchemy
sudo pip3 install tornado
git clone https://github.com/alberanid/diffido
cd diffido
./diffido.py --debug

Now you can point your browser to http://localhost:3210/

You can also run the server in https, putting in the ssl directory two files named diffido_key.pem and diffido_cert.pem

Settings

You can edit the conf/diffido.conf file (Python syntax) to change the global settings; you almost surely have to configure the SMTP settings, at least.

Each schedule has its own web page GUI; the settings should be pretty self-explanatory, except:

  • XPath selector: define which portion of a web page to consider
  • minimum change: float between 0.0 and 1.0, which represent the minimum amount of the page (in percentage of number of lines) that has to be changed to send a notification; if left empty, any change will be notified
  • crontab: a complete crontab definition, to specify the period of the check

Development

See the docs/DEVELOPMENT.md file for more information about how to contribute.
