> Base on this conversation, http://markmail.org/thread/t7pd773y4m6ncfyd it
> seems that the way Buildr handles versions can be improved.
> Here is what I suggest:
> # default behavior
> The default supported version scheme is the 3-digit number. Buildr releases
> VERSION_NUMBER minus -SNAPSHOT, and increments the last digit of that version
> to get the new version. The VERSION_NUMBER is then updated with the
> new-version, and the buildfile is committed.
> 1.0.0 -> 1.0.1
> If the VERSION_NUMBER does not match this pattern, then the release should
> fail.
> We could relax this convention to check if the last char is a digit and if so
> increment it.
> # custom increment
> If the default behavior does fit one's needs, the method Release.bump_version
> receives a block that lets the user implement his custom strategy. This will
> be consistent with Release#tag_name, and #commit_message.
> A buildfile could look like this:
> VERSION_NUMBER='1.0.0-rc1-SNAPSHOT'
> Release.bump_version = lambda { |version| # the version number without the
> -SNAPSHOT suffix, i.e. 1.0.0-rc1
> version[0..-2]+(version[-1].to_i+1).to_s # returns 1.0.0-rc2
> }
> The output of Release#bump_version is then used to update VERSION_NUMBER. And
> the buildfile is committed.
> When the version template changes - let's say you're done with the release
> candidates - you will manually edit the buildfile and change the version
> number to 1.0.0-SNAPSHOT. Then commit the buildfile.
