Pyrrot

Python Rotten Requirements

• Supports any remote repository that speaks PyPi's /json API through the --remote-location parameter
• Supports "human" and JSON output
• Uses the packaging module to parse and compare versions
• Inspired by piprot

Install

pip install git+https://github.com/Leryan/pyrrot

Usage

pyrrot -r requirements.txt [--reqreader package.ReqReaderClass] [--remote package.RemoteClass] [--output package.OutputClass]

Example

Default "human" output

$ pyrrot -r ~/someproject/requirements.txt > /dev/null
Beaker: old: wants: <1.6.0, latest: 1.9.0
influxdb: old: wants: ==2.12.0, latest: 5.0.0
pymongo: old: wants: <2.9.0, latest: 3.6.1
python-ldap: old: wants: <3.0.0, latest: 3.0.0

JSON output

$ pyrrot -r ~/someproject/requirements.txt --output pyrrot.remotes.JSON | python -m json.tool

{
    "psutil": {
        "old": false,
        "wants": "<5.5.0",
        "latest": "5.4.3"
    },
    "pymongo": {
        "old": true,
        "wants": "<2.9.0",
        "latest": "3.6.1"
    }
}

Hack it

Custom remote for latest versions

Create your own subclass of pyrrot.remotes.Remote and use it with --remote yourpackage.YourRemote. See pyrrot.remotes.PyPi for an example.

Custom output

See pyrrot.outputs.Human class. Create your own subclass of pyrrot.outputs.Output and use it with --output yourpackage.YourOutput.

This could allow you to put results in a database.

Todo

• Check requirements for currently installed package
• Support remote dependencies from git or any other VCS
• Support "pip options" like -e or -r
