Hi all,
In a command-line app of mine I want to have a --version flag, like
many GNU apps do to report their version. The only way I know to
provide the version number is to hardcode it in the source code
somewhere. That means I have the version number in two places: the
.cabal file and the source code. I just know that one day they'll get
unsynchronised, and --version will be wrong.
Is there any way to put the version number in _one_ place, and have
both the .cabal and source refer to it? Or even any easier way to
synchronise both version numbers?
Thanks,
Denis
