# RELEASING

# Places where hledger's version number makes an appearance:
#  hledger --version
#  hledger's cabal file
#  darcs tags
#  hackage tarball filenames
#  hackage pages
#
# Goals and constraints for our version number system:
# 1 automation, robustness, simplicity, platform independence
# 2 cabal versions must be all-numeric
# 3 release versions can be concise (without extra .0's)
# 4 releases should have a corresponding darcs tag
# 5 development builds should have a precise version appearing in --version
# 6 development builds should generate cabal packages with non-confusing versions
# 7 there should be a way to mark builds/releases as alpha or beta
# 8 it should be easy to darcs get the .0 release even after bugfix releases
# 9 avoid unnecessary compiling and linking
# 10 minimise rcs noise and syncing issues (commits, unrecorded changes)
#
# Current plan:
# - The release version looks like major.minor[.bugfix].  bugfix is 0 (and
#   may be elided) for a normal release, or 1..n for a bugfix release, or
#   98 meaning an alpha for the forthcoming release, or 99 meaning a beta.
# - The build version looks like major.minor.bugfix.patches, where patches
#   is the number of patches applied since the last release tag.
# - Set the release version in VERSION before "make" or "make release".
# - "make" updates version strings where needed, and defines PATCHES.
#   "make release" also records the version number changes and tags the
#   repo. (Todo: make cabal build set the version and PATCHES, also)
# - hledger --version shows the build version
# - The cabal package uses the release version
# - The release tag is the non-elided release version.

# Build a cabal release, tag the repo and maybe upload to hackage.
# Don't forget to update VERSION if needed. Examples:
# releasing 0.5:          set VERSION to 0.5, make release hackageupload
# doing a bugfix release: set VERSION to 0.5.1, make release hackageupload
# building 0.6 alpha:     set VERSION to 0.5.98, make
# releasing 0.6 beta:     set VERSION to 0.5.99, make release
