Introduction to pyvim

Do you use vim?

I have been using vi clone for over 30 years.

Currently, I use vim as vi, which comes by default with the OS.

Do you know pyvim?

Yes, pyvim is a pure python vim clone.

Original pyvim

https://pypi.org/project/pyvim/

• pyvim (and python-prompt-toolkit) has written by Jonathan Slenders
• pyvim seems experimental package to show the functionality of python-prompt-toolkit.
• A new version of pyvim has not been released in a few years.
• However, I saw great potential in this package as a vi clone!

Fork

https://github.com/nakagami/pyvim

• I have made it work with newer version python and dependent packages.
• I tried to make it work as much as possible the same as vi/vim.
• The key bindings I use on a daily basis work pretty well, now.
• But internally, I applied many monkey patches to python-prompt-toolkit.
• The purpose is different from the original pyvim, now.
• If any of the key bindings do not work, please create a github issue!
• Of course I will be happy if you send me a pull request.
