About a week ago, we have made available the monotone repositories of the Neurospaces Studio and the Project Browser. The installer script 'neurospaces_build' can now seemlessly pull from these repositories, and create a directory structure required for Neurospaces development. Preparing a developer PC can now be done in a couple of minutes. The distributed nature of the monotone version control system starts to play a crucial role for such functions to work correctly.

Over last weekend, I have also started working on a simple replacement for the Genesis 2 SLI. This new software component called GShell, allows to construct simple models, and then export them to the Neurospaces NDF format , and an SSP configuration file. This provides a basic interface to the Project Browser.

The GShell is basically agnostic about how to create a model. Instead of having hardcoded constructs for Neuroscience models, it pulls information from the model container, and transforms it using meta programming techniques to perl code that talks to the model container and allows to construct a model. A model container specific to air flow simulations would allow to create models of air flow using the GShell. Obviously the model container of the Neurospaces project only knows about elements of neuroscience models.

Because of the use of meta programming techniques, the source code of the GShell is only about 800 lines of code, and it can instantiate any model supported by the model container.
