semantic-release plugin for publishing Ruby gems.

| Step | Description | |
|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------|
| verifyConditions | Locate and validate a .gemspec file, locate and validate a lib/**/version.rb file, verify the presence of the GEM_HOST_API_KEY environment variable, and create a credentials file with the API key.| |
| prepare | Update the version in the lib/**/version.rb version file and build the gem. | |
| publish | Push the gem to the gem server. | |

Install

``bash
$ npm install semantic-release-rubygem -D
`

Usage

Add the plugin to the semantic-release configuration file:

`json
{
"plugins": [
"@semantic-release/commit-analyzer",
"@semantic-release/release-notes-generator",
"semantic-release-rubygem",
]
}
`

Configuration

$3

The gem server authentication configuration is required.

The API key must be set using the GEM_HOST_API_KEY environment variable. To retrieve the key, you can:
1. Login to RubyGems.org and click on 'Edit Profile'. You'll find the key in the 'API Access' section of the page.
2. Sign into your gem host using the gem signin command. After you enter your credentials, your API key will be stored as a YAML value in the ~/.gem/credentials file under the rubygems_api_key key (or the hostname of your gem server).

$3

This plugin requires exactly one valid .gemspec file to be present in the CWD.

$3

This plugin requires the version of the published gem to be defined in a version.rb file somewhere in the lib folder (e.g. lib/my/gem/version.rb). The version itself must be defined as a constant named VERSION inside the file:
`ruby
module My
module Gem
VERSION = '0.0.0'
end
end
