Good work needs to be utilised by many. Please upload your package to conda-forge.

Is there a way to list all the supported colormaps by the package as being done for matplotlib with plt.colormaps() command?

Due to changes in the matplotlib API (see https://matplotlib.org/stable/api/prev_api_changes/api_changes_3.9.0.html#top-level-cmap-registration-and-access-functions-in-mpl-cm) the colormaps package is incompatible with matplotlib versions 3.9.0 and above.
Trying to use the colormaps package results in the following error: AttributeError: module 'matplotlib.cm' has no attribute 'get_cmap' because of the aformentioned API change.

Tested with matplotlib versions 3.8.4 (no error is thrown) and 3.9.0 (the error exists).

Firstly, I should appreciate your effort in collating a large set of scientific colourmaps into a dedicated Python library. I have used it for application and for various other purposes. However, with the latest matplotlib release, I get AttributeError. Minimal example taken from README is as follows:

$ python

It would be nice to update your module to keep up with changes in the upstream matplotlib module.

I have a script that uses both GUI and the command line. When I use the script to be used as only the command line, it works without an issue. However, when invoking GUI which is based on PySide6, it produces the following error.

import colormaps as cmaps
  File "shibokensupport/signature/loader.py", line 61, in feature_imported
  File "shibokensupport/feature.py", line 135, in feature_imported
AttributeError: 'Cmaps' object has no attribute '__name__'

Not able to figure out what went wrong. Can you please help me out on this...

This issue is relevant to the issue mentioned at #8. Due to a conflict with PySide6 and colormaps, I could not use your package. Request you suggest a way to use it without installing it.

This is relevant to issue mentioned at https://github.com/pratiman-91/colormaps/issues/2. Can you please upload the package to PyPi? I am sure that this would put you one step closer to making package for conda-forge.

It is difficult to make the package install in automated mode for my project. I am sure that it does not make much time to upload to PyPi as you are already using setup.py.
