## 🌻 Synopsis

Give your next library an introspectable `Version` module without breaking your Gemspec.

```ruby
MyLib::Version.to_s # => "1.2.3.rc3"
MyLib::Version.major # => 1
MyLib::Version.minor # => 2
MyLib::Version.patch # => 3
MyLib::Version.pre # => "rc3"
MyLib::Version.to_a # => [1, 2, 3, "rc3"]
MyLib::Version.to_h # => { major: 1, minor: 2, patch: 3, pre: "rc3" }
```

This library was extracted from the gem _[oauth2](https://gitlab.com/oauth-xx/oauth2)_.

This gem has no runtime dependencies.


### 🧐 Alternatives

This gem has a very niche purpose, which is:

1. providing introspection of a `Version` module based on a `VERSION` constant string within it,
2. while not interfering with `gemspec` parsing where the `VERSION` string is traditionally used,
3. allowing 100% test coverage of Ruby code, including the `Version` module.

As proof in the pudding, this gem achieves 100% test coverage for lines and branches,
all 118 and 4 of them, respectively; coverage enabled in part by patterns from this library.
You can make it happen for your library too!

If this isn't **precisely** your use case you may be better off looking at
_[versionaire](https://www.alchemists.io/projects/versionaire)_, a wonderful, performant, well-maintained,
gem from the Alchemists, or _[version_sorter](https://rubygems.org/gems/version_sorter)_ from GitHub.

For more discussion about this [see issue #2](https://gitlab.com/oauth-xx/version_gem/-/issues/2)

## ✨ Installation

Install the gem and add to the application's Gemfile by executing:

```console
bundle add version_gem
```

If bundler is not being used to manage dependencies, install the gem by executing:

```console
gem install version_gem
```

### 🔒 Secure Installation

For Medium or High Security Installations

This gem is cryptographically signed, and has verifiable [SHA-256 and SHA-512][💎SHA_checksums] checksums by
[stone_checksums][💎stone_checksums]. Be sure the gem you install hasn’t been tampered with
by following the instructions below.

Add my public key (if you haven’t already, expires 2045-04-29) as a trusted certificate:

```console
gem cert --add <(curl -Ls https://raw.github.com/galtzo-floss/certs/main/pboling.pem)
```

You only need to do that once.  Then proceed to install with:

```console
gem install version_gem -P HighSecurity
```

The `HighSecurity` trust profile will verify signed gems, and not allow the installation of unsigned dependencies.

If you want to up your security game full-time:

```console
bundle config set --global trust-policy MediumSecurity
```

`MediumSecurity` instead of `HighSecurity` is necessary if not all the gems you use are signed.

NOTE: Be prepared to track down certs for signed gems and add them the same way you added mine.

## ⚙️ Configuration

In the standard `bundle gem my_lib` code you get the following in `lib/my_lib/version.rb`:

```ruby
module MyLib
  VERSION = "0.1.0"
end
```

Change it to a nested `Version` namespace (the one implied by the path => namespace convention):

```ruby
module MyLib
  module Version
    VERSION = "0.1.0"
  end
end
```

Now add the following near the top of the file the manages requiring external libraries.
Using the same example of `bundle gem my_lib`, this would be `lib/my_lib.rb`.

```ruby
require "version_gem"
```

Then, add the following wherever you want in the same file (recommend the bottom).

```ruby
MyLib::Version.class_eval do
  extend VersionGem::Basic
end
```

## 🔧 Basic Usage

Now you have some version introspection methods available:

```ruby
MyLib::Version.to_s # => "0.1.0"
MyLib::Version.major # => 0
MyLib::Version.minor # => 1
MyLib::Version.patch # => 0
MyLib::Version.pre # => ""
MyLib::Version.to_a # => [0, 1, 0]
MyLib::Version.to_h # => { major: 0, minor: 1, patch: 0, pre: "" }
```

### Side benefit #1

You can reference the version from your gemspec, keeping the version string DRY,
*and* still get accurate code coverage!

```ruby
# Get the GEMFILE_VERSION without *require* "my_gem/version", for code coverage accuracy
# See: https://github.com/simplecov-ruby/simplecov/issues/557#issuecomment-2630782358
# Kernel.load because load is overloaded in RubyGems during gemspec evaluation
Kernel.load("lib/my_gem/version.rb")
gem_version = MyGem::Version::VERSION
MyGem::Version.send(:remove_const, :VERSION)

Gem::Specification.new do |spec|
  # ...
  spec.version = gem_version
end
```

### Side benefit #2

Your `version.rb` file now abides the Ruby convention of directory / path matching the namespace / class!

### Epoch Usage (Epoch Semantic Versioning, as of version 1.1.7)

In the standard `bundle gem my_lib` code you get the following in `lib/my_lib/version.rb`:

```ruby
module MyLib
  VERSION = "0.1.0"
end
```

Change it to a nested `Version` namespace (the one implied by the path => namespace convention):

```ruby
module MyLib
  module Version
    VERSION = "0.1.0"
  end
end
```

The Epoch and Major versions are derived from the formula:

```
{EPOCH * 1000 + MAJOR}.MINOR.PATCH
```

This will start your library with the following version segments:

* `epoch = 0`
* `major = 0`
* `minor = 1`
* `patch = 0`
* `pre = nil`

And the segments are defined as:

```
EPOCH: Increment when you make significant or groundbreaking changes.
MAJOR: Increment when you make minor incompatible API changes.
MINOR: Increment when you add functionality in a backwards-compatible manner.
PATCH: Increment when you make backwards-compatible bug fixes.
```

Therefore, if you set your version number to:

```ruby
VERSION = "27016.42.86-pre.7"
```

You will get the following version segments:

```
{
  epoch: 27,
  major: 16,
  minor: 42,
  patch: 86,
  pre: "pre-7",
}
```

Now add the following near the top of the file the manages requiring external libraries.
Using the same example of `bundle gem my_lib`, this would be `lib/my_lib.rb`.

```ruby
require "version_gem"
```

Then, add the following wherever you want in the same file (recommend the bottom).

```ruby
MyLib::Version.class_eval do
  extend VersionGem::Epoch
end
```

And now you have some version introspection methods available:

```ruby
MyLib::Version.to_s # => "1024.3.8"
MyLib::Version.epoch # => 1
MyLib::Version.major # => 24
MyLib::Version.minor # => 3
MyLib::Version.patch # => 8
MyLib::Version.pre # => ""
MyLib::Version.to_a # => [1, 24, 3, 8]
MyLib::Version.to_h # => { epoch: 1, major: 24, minor: 3, patch: 8, pre: "" }
```

### Usage with Zeitwerk

The pattern of `version.rb` breaking the ruby convention of directory / path matching the namespace / class
is so entrenched that the `zeitwerk` library has a special carve-out for it. 🥺
RubyGems using this "bad is actually good" pattern are encouraged to use `Zeitwerk.for_gem`.

**Do not do that ^** if you use this gem.

#### Simple Zeitwerk Example

Create a gem like this (keeping with the `MyLib` theme):

```shell
bundle gem my_lib
```

Then following the usage instructions above, you edit your primary namespace file @ `lib/my_lib.rb`,
but inject the Zeitwerk loader.

```ruby
# frozen_string_literal: true

require_relative "my_lib/version"

module MyLib
  class Error < StandardError; end
  # Your code goes here...
end

loader = Zeitwerk::Loader.new
loader.tag = File.basename(__FILE__, ".rb")
loader.push_dir("lib/my_lib", namespace: MyLib)
loader.setup # ready!
loader.eager_load(force: true) # optional!

MyLib::Version.class_eval do
  extend VersionGem::Basic
end
```

#### Complex Zeitwerk Example

Maybe you would like to contribute one?

#### Query Ruby Version (as of version 1.1.2)

In Continuous Integration environments for libraries that run against many versions of Ruby,
I often need to configure things discretely per Ruby version, and doing so forced me to repeat
a significant amount of boilerplate code across each project.

Thus `VersionGem::Ruby` was born.  It has the two optimized methods I always need:

```ruby
engine = "ruby"
version = "2.7.7"
gte_minimum_version?(version, engine)  # Is the current version of Ruby greater than or equal to some minimum?

major = 3
minor = 2
actual_minor_version?(major, minor, engine) # Is the current version of Ruby precisely a specific minor version of Ruby?
```

`Version::Ruby` is *not loaded* by default.  If you want to use it, you must require it as:
```ruby
require "version_gem/ruby"
```

Normally I do this in my `spec/spec_helper.rb`, and/or `.simplecov` files.
Occasionally in my `Rakefile`.

### Caveat

This design keeps your `version.rb` file compatible with the way `gemspec` files use them.
This means that the introspection is _not_ available within the gemspec.
The enhancement from this gem is only available at runtime.

### RSpec Matchers

In `spec_helper.rb`:
```ruby
require "version_gem/rspec"
```

Then you can write a test like:

```ruby
RSpec.describe(MyLib::Version) do
  it_behaves_like "a Version module", described_class
end

# Or, if you want to write your own, here is the á la carte menu:
RSpec.describe(MyLib::Version) do
  it "is a Version module" do
    expect(described_class).is_a?(Module)
    expect(described_class).to(have_version_constant)
    expect(described_class).to(have_version_as_string)
    expect(described_class.to_s).to(be_a(String))
    expect(described_class).to(have_major_as_integer)
    expect(described_class).to(have_epoch_as_integer)
    expect(described_class).to(have_minor_as_integer)
    expect(described_class).to(have_patch_as_integer)
    expect(described_class).to(have_pre_as_nil_or_string)
    # This would be %i[epoch major minor patch pre] for epoch version schemes
    expect(described_class.to_h.keys).to(match_array(%i[major minor patch pre]))
    expect(described_class.to_a).to(be_a(Array))
  end
end

While ruby-oauth tools are free software and will always be, the project would benefit immensely from some funding.
Raising a monthly budget of... "dollars" would make the project more sustainable.

We welcome both individual and corporate sponsors! We also offer a
wide array of funding channels to account for your preferences
(although currently [Open Collective][🖇osc] is our preferred funding platform).

**If you're working in a company that's making significant use of ruby-oauth tools we'd
appreciate it if you suggest to your company to become a ruby-oauth sponsor.**

You can support the development of ruby-oauth tools via
[GitHub Sponsors][🖇sponsor],
[Liberapay][⛳liberapay],
[PayPal][🖇paypal],
[Open Collective][🖇osc]
and [Tidelift][🏙️entsup-tidelift].

| 📍 NOTE                                                                                                                                                                                                              |
|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| If doing a sponsorship in the form of donation is problematic for your company 
 from an accounting standpoint, we'd recommend the use of Tidelift, 
 where you can get a support-like subscription instead. |

### Another way to support open-source

> How wonderful it is that nobody need wait a single moment before starting to improve the world.
>—Anne Frank

I’m driven by a passion to foster a thriving open-source community – a space where people can tackle complex problems, no matter how small.  Revitalizing libraries that have fallen into disrepair, and building new libraries focused on solving real-world challenges, are my passions — totaling 79 hours of FLOSS coding over just the past seven days, a pretty regular week for me.  I was recently affected by layoffs, and the tech jobs market is unwelcoming. I’m reaching out here because your support would significantly aid my efforts to provide for my family, and my farm (11 🐔 chickens, 2 🐶 dogs, 3 🐰 rabbits, 8 🐈‍ cats).

If you work at a company that uses my work, please encourage them to support me as a corporate sponsor. My work on gems you use might show up in `bundle fund`.

I’m developing a new library, [floss_funding][🖇floss-funding-gem], designed to empower open-source developers like myself to get paid for the work we do, in a sustainable way. Please give it a look.

⭐️ Star History

## 📌 Versioning

This Library adheres to [![Semantic Versioning 2.0.0][📌semver-img]][📌semver].
Violations of this scheme should be reported as bugs.
Specifically, if a minor or patch version is released that breaks backward compatibility,
a new version should be immediately released that restores compatibility.
Breaking changes to the public API will only be introduced with new major versions.

> dropping support for a platform is both obviously and objectively a breaking change 
>—Jordan Harband ([@ljharb](https://github.com/ljharb), maintainer of SemVer) [in SemVer issue 716][📌semver-breaking]

I understand that policy doesn't work universally ("exceptions to every rule!"),
but it is the policy here.
As such, in many cases it is good to specify a dependency on this library using
the [Pessimistic Version Constraint][📌pvc] with two digits of precision.

For example:

```ruby
spec.add_dependency("version_gem", "~> 1.1")
```


📌 Is "Platform Support" part of the public API? More details inside.

SemVer should, IMO, but doesn't explicitly, say that dropping support for specific Platforms
is a *breaking change* to an API.
It is obvious to many, but not all, and since the spec is silent, the bike shedding is endless.

To get a better understanding of how SemVer is intended to work over a project's lifetime,
read this article from the creator of SemVer:

## 🤑 A request for help

Maintainers have teeth and need to pay their dentists.
After getting laid off in an RIF in March and filled with many dozens of rejections,
I'm now spending ~60+ hours a week building open source tools.
I'm hoping to be able to pay for my kids' health insurance this month,
so if you value the work I am doing, I need your support.
Please consider sponsoring me or the project.
