MOULTI

Moulti changes the way your shell scripts (bash, zsh, etc.) display their output in your terminal. Moulti enables you to assign the numerous lines emitted by your scripts to "steps", i.e. visual, collapsible blocks featuring their own title and color.

Here is how upgrading a Debian system looks like with Moulti:

Moulti is a tool meant for people who write and execute shell scripts. Specifically, if you find yourself scrolling up your terminal to ensure everything went fine while your script is still running, then Moulti is made for you.

How?

Synopsis:

  1. Start a Moulti instance: moulti init
  2. Add a step: moulti step add step_name --title='some clever title here'
  3. Fill it: whatever_your_script_does | moulti pass step_name
  4. Repeat #2 and #3 until your script is done.

When it comes to look and feel, Moulti can be customised:

Implementation

Moulti is written in Python and leverages Textual, along with Pyperclip and argcomplete.

Inspiration

Moulti remained a mere idea for a significant time (possibly years).

The idea of driving TUI elements from scripts obviously comes from tools like dialog and whiptail.

At some point, the author stumbled upon multiplex, which is probably the closest thing to Moulti. multiplex was deemed unsatisfying on multiple points (including architecture) and that prompted the development of Moulti.

procmux is also similar to Moulti but did not affect its development.

Acknowledgments
