Overview

pagan

Welcome to the Python Avatar Generator for Absolute Nerds.

Current version: 0.4.3

View the change history here.

Remember those good old days when your imagination was a big part of the computer gaming experience? Hardware limitations forced you to fill the void left by poorly pixelated images. Pagan brings back those nostalgic feelings by generating identicons in an old-school style inspired by retro roleplaying adventure games.

Pagan hashes input strings to generate unique avatar images intended for use as profile pictures in web applications. These images can be used to replace default user images for new accounts, or to enhance comment sections by visually representing a user's IP address or username.

Pagan is currently under development. It can perform the following functions:

Generate identicons with unique colors and gear based on any input string.
Use multiple hash functions from within Python's hashlib.
Create avatar images to fit a specific resolution.
Remap 16x16 generated pixelmaps to a required image size.
Expand generated pagans by adding new weapons or gear.

Enjoy the nostalgia!

Some example avatars hashed with SHA512:

Input	Avatar
pagan
python
avatar
github
retro
piece of cake
hash me if you can

Installation:

To install Pagan, first clone this repository:

>> git clone https://github.com/daboth/pagan.git

Then, enter this command at the terminal to manually install Pagan:

>> python setup.py install

Alternatively, use this command to install pagan via pip:

>> pip install pagan

Python usage example:

# Import the pagan module.
import pagan

# Acquire an arbitrary string.
inpt = 'pagan'

# Use pagan to generate an avatar object based on an input string.
# Optional: You may specify which hash function Pagan should use.
# The functions are available as constants.
# Default: MD5.
img = pagan.Avatar(inpt, pagan.SHA512)

# Open the avatar image in an
# external image viewer.
img.show()

# Set an output path and a file name.
# You don't need to specify a file ending.
# Choose a path depending on your OS.
outpath = 'output/'
filename = inpt

# Saves the avatar image as a .png file
# by omitting the path and name. The
# file endings will be generated automatically.
img.save(outpath, filename)

# You can change the avatar input and
# hash function anytime.
img.change('new input', pagan.SHA256)

Command Line Interface

The pagan command line interface can be used to generate avatars without needing to write a python script:

>> pagan [-h] [--show] [--output OUTPUT] [--hash HASH] input [input ...]

For example, typing

>> pagan hello

will generate an avatar from the string 'hello' and save it in the current working directory.

For more information, execute Pagan using the -h help parameter:

>> pagan -h

Webserver

A demo of Pagan can be run in a webserver application. To access the Pagan demo, execute the following instructions from the webserver directory:

>> cd /tools/webserver/
>> python webserver.py

Beware: This demo of Pagan will fill your temporary directory with generated image files. Do not run it in production!

The webserver will serve from localhost port 8080. Open this adress in your browser window:

http://127.0.0.1:8080/

Supported Hashes

Hash	Constant
md5	pagan.MD5
sha1	pagan.SHA1
sha224	pagan.SHA224
sha256	pagan.SHA256
sha384	pagan.SHA384
sha512	pagan.SHA512

Testing

To test Pagan, you must install either the pytest or tox Python modules. Configure tox.ini to test different Python versions.

Docker

To use pagan within Docker, you must build the Docker image with:

>> docker build -t pagan .

Then, run docker image

>> docker run -d -p 8080:8080 -t pagan

The webserver inside Docker will serve from localhost port 8080. Open this adress in your browser window:

http://127.0.0.1:8080/

If you want to use PAGAN CLI, you just have to look for the IP Adress of the Docker container and then connect through ssh with user: pagan and pass: pagan, like this:

>> ssh -X [email protected]

Using py.test

>> pip install pytest
>> pytest

Using tox

>> pip install tox
>> tox

Comments

Enable installation with setuptools >=58

setuptools v58.0.0 removed support for use_2to3 during builds. This patch simply adds a pyproject.toml that pins setuptools to a version smaller than 58.0.0. It's a bare minimum band-aid to get pagan to install with a new version of setuptools.

Fixed use_2to_3

Switching flag to false resolves pip installation erros and running python setup. At least in python 3.9. Errors:

#setup
python .\setup.py
error in pagan setup command: use_2to3 is invalid.

#pip
pip install pagan
Collecting pagan
  Using cached pagan-0.4.3.tar.gz (21 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py egg_info did not run successfully.
  │ exit code: 1
  ╰─> [1 lines of output]
      error in pagan setup command: use_2to3 is invalid.
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

Think leaving this as default config is neeeded since python2 is deprecated

Provide Docker Images [DONE]

The are currently no public Docker images available. An image would be useful for easy deployment of the webserver (in production and for testing purposes) as well as a convenient CLI without the need to install external dependencies.

docs: Fix a few typos
There are small typos in:

README.md

pagan/hashgrinder.py

Fixes:

Should read address rather than adress.

Should read variations rather than variatons.

Should read tuples rather than tupels.

Should read tuple rather than tupel.

Should read separate rather than seperate.

Update setup.py

removed use_2to3=True in setup.py installation results in error related to an update in setuptools

v58.0.2 06 Sep 2021 Misc #2769: Build now fails fast when use_2to3 is supplied.

i cloed it better to just fix setuptools version

Rework on templates

The templates to generate each figure are purely textbase, to enable everyone to contribute on this without any affinity or knowledge about programming. Do you think the system needs a rework? From my point of view, as i grew as a software/scientific guy, the currently implemented systems seems a bit outdated. Would appreciate everyones thought on that. This issue, by far however, is placed super late in my backlog, so take your time.

Increase virtual resolution to add more detail

Hello again. This is a big one. I really liked the original idea to limit myself on the overall virtual pixel output. What are your thoughts about increasing the size to generate more detailed figures and maybe even add background generation in this process. I'm aware that it would have a mayor impact on the idea, so i'd really like to read your thoughts on this one.

Support for cropped circles

Hello everyone. I lack the power to describe this topic, but you know the trend where every app takes your image and crops a circle from it? Yes, this looks bad with the native pagan output and will surely take some workaround if you consider pagan as a tool in an automated process. So i'm open for suggestions here. The first thing i could think of would be to just generate a bigger "outer space" around the actual image, but i'd like to reach out for a better, more "standalone too" option to cover this case.

Colorful Backgrounds

Hello to all supporters and a very special "Thank you" for using pagan in your projects. I never thought this one would draw such attention and i'm overwhelmed by the positive feedback it got. I got back into programming a while ago, so let's start out with some ideas. The first one being backgrounds. It always bothered me, that the backgrounds are plain as can be. Instead i started looking for some mechanics to generate some overall color metric from the generated virtual pixels to add a background in complementary colors to the mix. The challenge is to generate a background that does not only avoid to obfuscate the drawn figures, but actually highlight them, so that every result from pagan is a good and usable complete image.

Removed webserver, minor changes
remove pagan webserver stuff from repo and move stuff to new repo

fix pylint complains about docstring format in pagan

pagan console version saves avatar to file, when none is specified it is saved to "input" "$ pagan /etc/password " would save avatar for input /etc/password to file /etc/password.png changed to only allow letters and digits, replace other characters to "-" "$ pagan /etc/password" saves to -etc-password.png

pagan console, add --noshow option, to supress opening of viewer

add test case for console pagan, add more tests
