This package is a collection of programs that we use at Eaton to interact with, debug, and analyze data from vehicle ECUs (Electronic Control Unit: automotive speak for an embedded computer). The motivation to put this stuff on hackage is to encourage the use of Haskell in automotive electronics and to help standardize open data formats and protocols -- the most common formats and protocols in this industry are proprietary. (The other motivation for hackage is it makes it easy for us to distribute tool updates to our engineers and technicians in the field. :-) ) Most of these programs in this package read or write data on a CAN bus. At work we use Kvaser CAN cables, so these tools link in Kvaser's open source CAN driver library, canlib. However, we anticipate adding several tools that have nothing to do with CAN -- they could be general data analysis programs that could be applicable to other fields, not just automotive. My question is, is it possible for a user to select which programs to install within a given package? I could see where someone would want to install a data analysis tool, but not want to bother with separately installing Kvaser canlib. I had considered different packages for the individual tools, but that would get messy pretty quick, especially since many tools share a lot of common code. Another question: Can we get a Hackage category specifically for the use of Haskell in embedded systems? I didn't see anything that stood out. And one last question: The Kvaser canlib library has a different name depending on if the machine is Linux or Windows. What is the best way to configure the build based on the platform? Current I have the library name hard coded in the extra-libraries field in the cabal file. -Tom http://hackage.haskell.org/package/ecu http://github.com/tomahawkins/ecu
