## NAME

## SYNOPSIS

**mu-editor** \[*file*\]

## ARGUMENTS

- *file*

## DESCRIPTION

**mu-editor** is a simple code editor for beginner programmers based on extensive feedback from teachers and learners. Having said that, mu-editor is for anyone who wants to use a simple “no frills” editor.

**mu-editor** is a modal editor with modes for:

- •

  Adafruit’s CircuitPython

- •

  the micro:bit’s version of MicroPython

- •

  PyGame Zero

- •

  standard Python 3 (including a graphical debugger)

Some of the modes make available a REPL (either running on the connected CircuitPython or MicroPython device, or as a Jupyter-based iPython session in Python3 mode).
