We have package managers for everything nowadays, then why keep our beloved cows behind...they are no less (believe me, I know !).

---

Naming conventions

• The barn refers to the project's home directory (~/cpm).
• Fortune cookie (or simply cookie) refer to a category of fortune messages.
  You can view which categories will be taken into account and their respective probabilities while generating cookies by executing fortune -f.

How it works ?

You can fetch a cow right into your barn (make sure you spell correctly, cows hate it when you misspell their names) -

./cpm fetch <cow_name>

You can also update your entire barn with all the new cows lurking out there -

./cpm fetch

Perhaps you might also find the above command useful in case some of your cows fled without you knowing (believe it or not, there have been many such reported cases !).

Each time you fire up your login shell, the cow_selector script runs. It randomly generates a fortune message, and gets the respective fortune cookie. It then looks in the cookie_index for all the cows that correspond to that cookie and randomly picks one.

But there is a catch !!

While generation of a random cookie is taken care of by the fortune command, the cow which gets displayed along is decided by the cow_selector script. And for that to happen the generated cookie needs to be associated with atleast one cow. The more entries there are in cookie_index, the more cow-cookie diversity will be there each time you start your shell.
The cookie_index gets populated when you run update_cookie_index script. In case the generated cookie is not associated with any cow, a randomly generated cow is used.
So, for the results to get better, more and more cookie entries are required in the cow files. And this is where your valuable contributions come in. Add cookies which you think are most suitable for your favourite cows. The more entries you make, the better your (and everyone's) shell will become.
Currently, the cookie_index is extremely minimal with a single populated entry.

Requirements

• cowsay
• fortune (available by default in most distros)

Installation

The installation script is brief -

git clone https://github.com/shivrai/cpm.git && cd cpm
./install

Uninstallation

Alas, not every association is meant to last forever. Hope you enjoyed your cows!

./uninstall

Contributing

Have a new ASCII art ? Want to associate a cow with new cookies ? Pull requests are more than welcome.

After adding new cows, update cow_index by running -

ls cows >! cow_index

After adding adding cookies to cow files, run the following command -

./update_cookie_index

This will automatically update the cookie_index with all the new cow(s) associated with their corresponding cookies.

Some conventions to be taken care of while making changes -

• When adding new cookies to cow files, make sure you use a , for delimiting.
• Avoid using . in cow names.
• Do not manually tamper with the cow_index. This may break some functionality and produce odd results.

Todo

• Add feature for specifying probability/score along with cows associated with each cookie to control their chances of occurrence.
• If a cookie is removed from a cow, add functionality in update_cookie_index to automatically make relevant changes in cookie_index.
