If you are installing from a built source distribution then the command:-

python install -d <DirectoryToInstallInto>

should work.

You will need to have Python and if you don't have root privileges you will also need python virtualenv and setuptools already installed, and windows users should see the note under pyparsing below.

Additionally there are two other packages I also advise installing first is mercurial 1.9 or higher, although technically not required the only save format which is currently support and included requires it. The next is wxPython which is required if you wish to use the graphical Ui.'s install will create a python virtualenv in the specified installation directory and install MysteryMachine, a customised yapsy plus all of the dependencies into to it.

You can still install MysteryMachine into you global environment if you don't have or want to install virtualenv by running

python install_here

instead. But to do this you will need write access to the global environment.

On windows you may need to elevate to Administrator access and on a Linux or Mac you will need to either sudo , or run athe comand as root.

If you are installing from the mercurial repo you need the following libraries on your PYTHONPATH. Once the libraries below and MysteryMachine itself are on your python path the scripts in the 'scripts' directory should work. Or you can install a patched version of yapsy (patch is in the patches directory) and paver then use:-

paver sdist

to build you own source distribution and install from that.

Unfortuantely virtualenv changes it defaults in 1.7 so you will need my paver 1.1.0 or greater if you wish to build and installer that works with it. Again a custom patched version of paver can be found in my github account.

You will also find it useful to install wxPython and mercurial (at least 1.9) seperately . Similiary bpython is recommended for cli affiondadios on platforms which support it.

Windows Install Quick Reference

To install on windows I suggest the following commands, if you use python for other applications want more control I suggest you read all of this README before doing this

  1. Download a recent Python (2.6.x is recommended) from and install it.
  2. Download a recent wxPython (2.8.10 is recommoned) from and install it.
  3. Download mercurial from and install it.
  4. From the MysteryMachine zip file run
    python install -d c:mysterymachine

5 Add a Link to the mmcli.exe and mmwx.exe scripts to your Start Menu.

Installation on Debian/Unbuntu

  1. Run 'aptitude install python2.6 python-wxgtk2.8 mercurial'
  2. From the MysteryMachine zip file run
    python install -d /opt/mysterymachine
3 Add a Link to the /opt/mysterynachine/mmcli and /opt/mysterymachine/binmmwx
to your desktop

Libraries Required

You will need to install the following Python packages to use the MysteryMachine .

mercurial > 1.9.0

(Note, Pyparsing was included here but now handles that dependency for you)


Yapsy does not currently meet our python3 or other requirements.

MysteryMachine ships with a patched version of Yapsy which should be backwardly compatible with 1.7 - but adds a filter mechanism which is currently used so we ignore UnTrusted plugins.


MysteryMachine no longers needs to be able to use Mercurial as a library , but does require mercuial 1.9 or later for the cmd server feature.

However this be now be the standard version pyexe, or other binary version of mercuial downloaded form the usual sources (ie. .


This package is no longer considerer required as it doesn't work on windows, however it is recommended on those platforms where it does work.

Use easy_install or your OS package manager to install it. If it ia not already installed the installer will try to fetch and install it automatically.


MysteryMachine was first developed with docutils 0.4 but I'm currently using 0.6 myself as it generates less noise of on the python comaptiblity tests. I suspect 0.5 and 0.6 should work equally. 0.4 will probably work too but I haven't tested it in a while.

Docutils can either be installed wiht easy_install or the installer will pull in the latest version for you.


Yaml is the current prefered format for the MysteryMachine config file , and if you intend to start MysteryMachine with it default settings it will need PyYaml. PyYaml can be install easily using easy_install. Like so:

easy_install pyyaml

But it should pulled in with the installer.

Tkinter & Tcl/Tk

These are only require for the Idle based Ui, but currently the installer doesn't setup the tcl/tk environment correctly (see ) to fix this you need ensure the TCL_LIBARRY environmenr variable point to the TCL script and srtart up files. The easiest way to do this is to add a line to your activate.bat which set this varaibell to pint to the tcl directories tghat ship with python.

Running MysteryMachine



will start the default MysteryMachine API cli for your platform.

Mystery machine has a two Cli ui's at the moment which dumps you at the python shell with the global 'ctx' bound to MysteryMachine Library.

The are basically identical, the primary one is base on bpython and can be started like this:

mysterymachine --ui=Ui.cli.BPython

Bpython support auto completion and help pop-up documentation. The down side of Bpython is that it requires a Unix (or unix-like) terminal to run in, so is not compatible with windows.

For windows , althought it shoulkd work anywhere that has python there is an alternative Ui based on the Idle development environment, this Ui can be started like this:-

mysterymachine --ui=Ui.cli.Idle

Similiarily this supports auto-completion and pop-up documentation but where as Bpython will show the complete docstring, Idle tries to shorten it.

Your more likely to be interested in running the New MysteryMachine GUI and this can be starting by running the mmwx binary from either the bin or scripts directory depending on your platform.
