peepin 0.9

Edits your requirements.txt by peep-hashing them

This tool makes it easier to update your strict “peep-ready” requirements.txt file.

If you want to add a package or edit the version of one you’re currently using you have to do the following steps:

1. Go to pypi for that package

2. Download the .tgz file

3. Possibly download the .whl file

4. Run peep hash downloadedpackage-1.2.3.tgz

5. Run peep hash downloadedpackage-1.2.3.whl

6. Edit requirements.txt

This script does all those things. Hackishly wonderfully so.

A Word of Warning!

The whole point of peep is that you vet the packages that you use on your laptop and that they haven’t been tampered with. Then you can confidently install them on a server.

This tool downloads from PyPI (over HTTPS) and runs peep hash on the downloaded files.

You still need to check that the packages that are downloaded are sane.

You might not have time to go through the lines one by one but you should be aware that the vetting process is your responsibility.

Installation

This is something you only do or ever need in a development environment. Ie. your laptop:

pip install peepin

How to use it

Suppose you want to install futures. You can either do this:

peepin futures

Which will download the latest version tarball (and wheel) and calculate their peep hash and edit your requirements.txt file.

Or you can be specific about exactly which version you want:

peepin "futures==2.1.3"

Suppose you don’t have a requirements.txt right there in the same directory you can do this:

peepin "futures==2.1.3" stuff/requirementst/prod.txt

If there’s not output. It worked. Check how it edited your requirements files.

Runnings tests

Simply run:

python setup.py test

Ode to Erik Rose

Just in case you didn’t know; peep is awesome. It makes it possible to confidently leave third-party packages to be installed on the server without needing to be checked into some sort of “vendor” directory.

Having said that, if you don’t care about security or repeatability. Then Erik is just a dude with a goatee.
