There’s a presentation of pter in motion on asciinema.

Also in this package, the QT5 based graphical user interface, qpter.

pter has a bunch of features that help you managing your todo.txt file:

  • Fully compatible to the todo.txt standard
  • Support for due:, h:, t:, rec:, id:
  • Save search queries and sorting for quick access
  • Convenient entering of dates
  • Time tracking, notes, task delegation
  • Connect tasks in sequences
  • Template system and auto-completion for ease of creating tasks
  • Support for archive and trash
  • Can work with multiple todo.txt files at the same time
  • Configurable behaviour, shortcuts, and colors

There is also a graphical user interface called qpter, but some features are missing.


Install using pipx

To install pter using pipx, run this:

    pipx install pter

If you wish to use qpter, the graphical version of pter, make sure you pass this option to pipx:

    pipx install pter[qt]

Install from PIP

This is the deprecated way to install pter; instead rather use pipx; see above.

To install pter you can either clone the repository (see at the end) or, much simpler, use pip to install it:

    pip install pter

If you want to use the Qt GUI qpter, you have to install PyQt5::

    pip install PyQt5

Using pter

To launch pter you have to tell it where your todo.txt file is:

    pter ~/todo.txt

For the graphical user interface (requires QT), you have to start it like this:

    qpter ~/todo.txt

Both will give you a listing of all your tasks order by how soon they will be due and what priority you have given them.

You can navigate the tasks with your cursor keys and edit selected tasks by pressing e.

More default shortcuts are:

  • e, edit the selected task
  • n, create a new task
  • d, mark the selected task as done (or toggle back to not done)
  • ?, show all keyboard shortcuts
  • q, quit the program

There is a complex search available (have a look at the manual for details), but the short version is:

  • press / to enter your search terms
  • search for done:n to only show incomplete tasks
  • search for a context with @context
  • search for a project with +project
  • search for tasks that do not belong to a context with -@context or not:@context
  • press Return to return the focus to the task list

Using qpter

To launch the Qt GUI, you may (but don’t have to) provide the location of your todo.txt file::

    qpter ~/todo.txt


Just like any other open source project, you’re invited to participate in pter’s development. Any contribution is welcome, from bug reports to pull requests/sending of patches!

You can find the project at codeberg or just email any of the authors with your input.
