The textobj-hydrogen plugin provides two new text-objects, ah and ih, and backwards and forwards motion for them, [h and ]h respectively. You can use them when you have to deal with hydrogen style python notebook cells. These are usually encountered when transforming jupyter notebooks to plain text files with tools such as jupytext and notedown.

All code cells start with # %% . The end of the cell is implicitly defined by either a new cell marker or the end of the file. The ah object includes the marker line while the ih does not. Both commands treat the end of the cell in the same way.

The new objects and motions combined with a plugin that will allow the user to send input to a REPL running along the editor allows for an enhanced Jupyter notebook like experience.

My prefered method of installation is using the Plug plugin manager. For it to work you will need to have kana/vim-textobj-user and this repo installed.

Plug 'kana/vim-textobj-user'
Plug 'GCBallesteros/vim-textobj-hydrogen'
