Hi,
I'd like my program to print something like this is $program 1.0.4 git
45fea6b when invoked with --version, or at least just the 1.0.4 part.
Can Cabal expose the version as a preprocessor macro by default, or do I
have to use Build-Type: Custom and add a preprocessing step of my own?

For each package myPackage Cabal generates a module containing,
among other things, the package's version as a Haskell value:

Thanks, this is exactly what I was looking for!

At any rate, it looks like you're over-eager for the bleeding edge.
KU hasn't even released 0.2.5 to hackage, as you noted, and users
aren't typically expected to pull the latest from the source
Thanks for the quick reply.
Yup. I have search repo logs. I am not entirely sure what do you mean by
