If todoman is packaged for your OS/distribution, using your system’s standard package manager is probably the easiest way to install khal:

  • ArchLinux (AUR)

Install via PIP

Since todoman is written in python, you can use python’s package managers, pip by executing:

pip install todoman

or the latest development version by executing:

pip install git+git://

This should also take care of installing all required dependencies.

Manual installation

If pip is not available either (this is most unlikely), you’ll need to download the source tarball and install via, though this is not a recommended installation method:

python3 install


Todoman requires python 3.3 or later. Installation of required libraries can be done via pip, or your OS’s package manager.

Todoman will not work with python 2. However, keep in mind that python 2 and python 3 can coexist (and most distributions actually ship both).

Recent versions also have experimental support for pypy3.

Notes for Packagers

All of todoman’s dependencies are listed in the requirements.txt file. New dependencies will be clearly announced in the CHANGELOG.rst file for each release. Patch releases (eg: those where the third digit of the version is incremented) will not introduce new dependencies.

If your packages are generated by running install or some similar mechanism, you’ll end up with a very slow entry point (that’s the file /usr/bin/todo file). Package managers should use the file included in this repository under bin/todo and replace the above one.

The root cause of the issue is really how python’s setuptools generates these and outside of the scope of this project.

If your packages are generated using python wheels, this should not be an issue (much like it won’t be an issue for users installing via pip).
