Pygenda is a calendar/agenda application written in Python3/GTK3 and designed for clamshell "PDA" devices with keyboards such as Planet Computers' Gemini PDA and Cosmo Communicator (running Linux). The user interface is inspired by the Agenda programs on the Psion Series 3 and Series 5 range of PDAs.
WARNING: This is in-development code, released for testing/feedback and as a preview for developers. The software is provided as-is, with no guarantees. You should back up any files or data used by Pygenda (e.g. iCal files or data stored on calendar servers).
There are currently lots of missing/incomplete features as well as bugs. For a list of known issues, see: known_issues.md. If you find any new bugs, please send them to [email protected], or raise them as issues on GitHub.
However, it currently has Week, Year and Todo Views that are functional enough that the author is now using Pygenda as his main agenda, so maybe other people will also find it useful. Feedback is welcome at [email protected] – suggestions, questions about how to get something working, or just to say that you tried it out.
The simplest way to get started is to follow one of the following "quick start" guides (only a few devices, so far):
- Gemini PDA running Gemian
- Cosmo Communicator running Gemian
- PostmarketOS
- Debian-like systems e.g. Raspberry Pi OS (but see above for Gemian)
More technical information is given below and in linked documents for those who want/need it.
(I'd like Pygenda to be available in Mobile Linux repositories so that it's more easily installable. If you can help with that it would be very welcome.)

- Python3. Version >=3.5 (because Gemini's "Gemian" Linux provides Python 3.5).
- GTK+3 library
- Python libraries: PyGObject3 (for gi), pycairo, icalendar, python-dateutil, tzlocal, num2words.
If you want to access a CalDAV server from Pygenda there are some extra dependencies. See setup details in: CalDAV.md
If possible, install the Python libraries from the OS repositories. This should reduce the chance of pip3 installing a version of a library that is not compatible with other OS components.
If you have pip installed, this is the simplest way to get the latest release (best for testing). The "quickstart" guides above can serve as a guide.
If you want to try the latest development code (best for contributing) then get the version from GitHub.
If you have installed the dependencies then you can run Pygenda directly from the root directory of the project (containing this readme), with the command:
python3 -m pygenda
Better/recommended: install the Python module with (for example)...
pip3 install --editable . --user
Or, for older versions of pip/Python:
./setup_old.py develop --user
(In either case you can uninstall the module with pip3 uninstall pygenda.)
Now you can now run Pygenda from anywhere with:
python3 -m pygenda
There are a few command-line options, which you can view using:
python3 -m pygenda --help
For more complete settings, see "Configuration", below.
Configuration settings go in file: ~/.config/pygenda/user.ini
Custom CSS goes in: ~/.config/pygenda/pygenda.css
More information: docs/config-examples/README.md
If you're running Pygenda on a handheld device, the default font sizes
etc. will probably not be appropriate for the screen size. These can
be fixed by providing custom CSS. An example for the Gemini PDA is in
pygenda/css/gemini.css. If it works as provided, then it can be
imported into your ~/.config/pygenda/pygenda.css file by adding the
line:
@import "PATH_TO_GEMINI_CSS_FILE";
The "startup/maximized" and "startup/fullscreen" options are also useful for devices with small screens.
A sample pygenda.desktop file is provided in pygenda/app/. This
should help adding launch icons to the desktop menu/panels etc.
For example, to add it to your menu, create a softlink from
~/.local/share/applications/.
See: Usage.md
Calendar data can be stored as an iCal file, or via a CalDAV server, or via an Evolution Data Server (EDS). An iCal file is the default, because it works without configuration, but a server is recommended for real use. Using EDS is simpler than a CalDAV server and will probably be the preferred way going forward. However, it is new and less well tested than using CalDAV, so it might be more buggy.
- CalDAV configuration: CalDAV.md
- EDS configuration: Evolution_Data_Server.md
The default iCal file is created in ~/.config/pygenda/pygenda.ics
but you can change this from the command line or config file.

If you want to compare the "competition", the Gemian people also have an in-development agenda-like app designed for the Gemini/Cosmo. Details at https://gemian.thinkglobally.org/#Calendar
