babi
a text editor, eventually...
installation
pip install babi
babi works best in a virtualenv
why is it called babi?
I used to use the text editor nano
, frequently I typo this. on a qwerty
keyboard, when the right hand is shifted left by one, nano
becomes babi
.
babi vs. nano
here is a youtube video where I discuss the motivation for creating and using
babi
instead of nano
:

setting up syntax highlighting
syntax highlighting should work out of the box!
if you want a custom theme find a visual studio code theme, convert it to
json (if it is not already json) and put it at ~/.config/babi/theme.json
.
a helper script is provided to make this easier: ./bin/download-theme NAME URL
keyboard shortcuts on macos
to get the most out of babi's built in keyboard shortcuts, a few settings must be changed on macos with Terminal.app:
- in System Preferences: Keyboard > Shortcuts >
Mission Control: disable or rebind "Move left a space" and
"Move right a space" (the defaults
โ โ
andโ โ
conflict) - in Terminal.app: Terminal > Preferences > Profiles >
Keyboard:
- check Use Option as Meta key
- ensure the following keys are enabled:
โ โ
:\033[1;5C
โ โ
:\033[1;5D
โง โ
:\033[1;2A
โง โ
:\033[1;2B

demos
most things work! here's a few screenshots
file view
this opens the file, displays it, and can be edited and can save! unknown keys are displayed as errors in the status bar. babi will scroll if the cursor goes off screen either from resize events or from movement. babi can edit multiple files. babi has a command mode (so you can quit it like vim :q!). babi also supports syntax highlighting
