Use constants to specify the version of your gem· 1 min read
When developing gems or external libraries we frequently write the semantic versioning as a string.
module MyGem VERSION = '1.4.0' end
And when releasing a new version, git diff will show us this line was modified.
Why not use a constant for each semver element instead?
Rewriting the previous version like this:
module MyGem MAJOR = 1 MINOR = 4 PATCH = 0 VERSION = [MAJOR, MINOR, PATCH].join('.') end
It will allow us to keep our git diff clean when releasing, and also make our version string less prone to typos.
