pyganja's Issues

Replace files with html_to_data_uri

see https://github.com/cztomczak/cefpython/blob/master/examples/tutorial.py

Update readme to be more useful

Add the various ganja drawing flags as options to the draw objects functions

Add a license

MIT probably makes sense, as ganja.js uses that.

Change point pair display to show the line between the points

Jupyter notebook outputs appear in the wrong places

Continuation of pygae/clifford#170

The plots are no longer repeated, but they still appear in the wrong places: https://clifford.readthedocs.io/en/latest/Example%201%20Interpolating%20Conformal%20Objects.html

This is due to something like:

<script>
call_soon(()=>document.write("a"));
</script>
b
<script>
call_soon(()=>document.write("c"));
</script>

which can output bac or even bca depending on how call_soon behaves (in this case, requirejs)

cefpython draw fails on windows

See pygae/clifford#85

Include the readme on PyPI

Would be nice to have the readme contents here: https://pypi.org/project/pyganja/

There are some simple instructions about how to do that here: https://packaging.python.org/guides/making-a-pypi-friendly-readme/

Modify generated script to use faster static data parameter

PyGanja not working in VSCode Jupyter

VSCode can directly open jupyter notebooks (https://code.visualstudio.com/docs/python/jupyter-support). However PyGanja's draw doesn't show up in them.

Display camera rotor by default in canvas

See:
enkimute/ganja.js#35

Error in 0.0.4 on PyPI

Works locally, but when installed via PyPI gives:

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\wiese\\AppData\\Roaming\\Python\\Python35\\site-packages\\pyganja/static/ganja.js/ganja.js'

bug in repr dunder from GanjaScene class

Drawing fails on Google Colab

I used the follow in Google colab notebook

!pip install clifford
!pip install pyganja

from clifford.tools.g3c import random_line
from pyganja import *

draw([random_line() for i in range(10)])

And I get the follow error

/usr/local/lib/python3.6/dist-packages/pyganja/__init__.py:2: UserWarning: Failed to import cef_gui, cef functions will be unavailable
  from .script_api import *
---------------------------------------------------------------------------

    259         return str(sc)
    260     elif isinstance(objects, str):

NameError: name 'color' is not defined

v0.0.4 has a setup.py with a version of 0.0.3

Would recommend releasing during business hours next time ;)

Cefpython window does not work with installed module

Script does not have permission to write to the site-extensions directory, need to move away from files

Allow draw to take a GanjaScene directly

Also it should be able to handle str(GanjaScene)

Add browser control option

In the case that a user does not have jupyter or cefpython we should simply generate html and point the users browser to that html

pyganja in Jupyterlab - by ext only?

Finding pyganja works superbly in Jupyter notebooks,
but Jupyterlab places restriction against unmediated javascript.
Option is to write an extension, but thought to ask if you
have recommendation in this direction.
Thank you for your incredibly good work!
