Adding a new wavelet/ issues with using a development fork

[lxpaul]

Hello,

first off: thank you for this helpful package.

I'd like to use a continuous wavelet that isn't (yet?) implemented in PyWavelets. The poisson kernel wavelet, which is quite simple and somewhat similar to the mexican hat one.

To do that I created a fork and made the additions that I believe are needed on the in the following files:

• pywt/_extensions/_cwt.pyx
• pywt/_extensions/c/cwt.template.c
• pywt/_extensions/c/cwt.template.h
• pywt/_extensions/c/wavelets.c
• pywt/_extensions/c/wavelets.h
• pywt/_extensions/c_wt.pxd
• pywt/_extensions/wavelets_list.pxi

(Basically everywhere that the mexican hat one was mentioned, I added the equivalent for the poisson kernel.) Did I miss any?

I now have a lot of trouble using my own fork of pywavelets as a package.

I tried importing it from my github with pip install -e git+git://github.com/lxpaul/pywt#egg=pywavelets But I can't manage to import it afterwards. (I tried a lot of things but I must admit I am still very new to source control and even more to package development) Any clues or help?

I guess the issue came from still using Python 3.11.

Using Python 3.12 solved it.
