vimnb

Vim notebook, mimicking IPython notebooks

Install

Make sure the files pywrap.py and vimnb are executable. Make sure vimnb is in your path. Edit vimnb so that the variable FILEDIR points to the location of all other files.

Usage

Call vimnb on your favourite python script, and execute parts of the code by selecting them, and hitting <Space>. Watch the magic happen.

Codeblocks

VimNB has a notion of codeblocks. It are pieces of Python code delimited by #{{{ and #}}}. To create a codeblock, hit <Ctrl-N>b.

Keyboard shortcuts

• <Ctrl-N>b to create a codeblock.
• <Ctrl-N>r to run a codeblock.
• <Ctrl-N>e to run a codeblock, and jump to the next.
• <Ctrl-N>s to split a codeblock.
• Use [b (resp. ]b) to jump to the start of the previous (resp. next) codeblock.
• Use [B (resp. ]B) to jump to the start of the end (resp. next) codeblock.
• There are vim textobjects:
  • ab operates on an entire codeblock
  • ib operates on the code in a codeblock
  • io operates on the output of a codeblock For example: dio deletes the output (make sure the cursor is on the output) In the same spirit, cib changes the code of the codeblock, vab selects the entire codeblock, and zfio folds the output.
