## Unreleased

## v5.0.0 - 2024-07-03

- **breaking**: The graphql gem 2.2.0+ breaks some of the parsing and displaying of comments from a GraphQL schema file
- **breaking**: Ruby 2.6, 2.7, 3.0 are no longer supported as they are End of Life (EOL)
- feat: CLI version flag: `graphql-docs --version` / `graphql-docs -v`
- fix: CLI now works outside of a Bundler project
- fix: test suite
- chore: switch to sess-embedded gem for more maintained dependency

Add the gem to your project with this command:

``` console
```console
bundle add graphql-docs
```

Or install it yourself as:

``` console
```console
gem install graphql-docs
```

## Usage

GraphQLDocs can be used as a Ruby library to build the documentation website. Using it as a Ruby library allows for more control and using every supported option. Here's an example:

``` ruby
```ruby
# pass in a filename
GraphQLDocs.build(filename: filename)

GraphQLDocs also has a simplified CLI (`graphql-docs`) that gets installed with the gem:

``` console
```console
graphql-docs schema.graphql
```

That will generate the output in the `output` dir.

See all of the supported CLI options with:

``` console
```console
graphql-docs -h
```

## Breakdown

There are several phases going on the single `GraphQLDocs.build` call:

* The GraphQL IDL file is read (if you passed `filename`) through `GraphQL::Client` (or simply read if you passed a string through `schema`).
* `GraphQL::Parser` manipulates the IDL into a slightly saner format.
* `GraphQL::Generator` takes that saner format and begins the process of applying items to the HTML templates.
* `GraphQL::Renderer` technically runs as part of the generation phase. It passes the contents of each page and converts it into HTML.

If you wanted to, you could break these calls up individually. For example:

``` ruby
```ruby
options = {}
options[:filename] = "#{File.dirname(__FILE__)}/../data/graphql/schema.idl"
options[:renderer] = MySuperCoolRenderer

## Generating output

By default, the HTML generation process uses ERB to layout the content. There are a bunch of default options provided for you, but feel free to override any of these. The *Configuration* section below has more information on what you can change.
By default, the HTML generation process uses ERB to layout the content. There are a bunch of default options provided for you, but feel free to override any of these. The _Configuration_ section below has more information on what you can change.

It also uses [html-pipeline](https://github.com/jch/html-pipeline) to perform the rendering by default. You can override this by providing a custom rendering class.You must implement two methods:

* `initialize` - Takes two arguments, the parsed `schema` and the configuration `options`.
* `render` Takes the contents of a template page. It also takes two optional kwargs, the GraphQL `type` and its `name`. For example:
- `initialize` - Takes two arguments, the parsed `schema` and the configuration `options`.

In your ERB layouts, there are several helper methods you can use. The helper methods are:

* `slugify(str)` - This slugifies the given string.
* `include(filename, opts)` - This embeds a template from your `includes` folder, passing along the local options provided.
* `markdownify(string)` - This converts a string into HTML via CommonMarker.
* `graphql_operation_types`, `graphql_mutation_types`, `graphql_object_types`, `graphql_interface_types`, `graphql_enum_types`, `graphql_union_types`, `graphql_input_object_types`, `graphql_scalar_types`, `graphql_directive_types` - Collections of the various GraphQL types.

To call these methods within templates, you must use the dot notation, such as `<%= slugify.(text) %>`.

## Supported Ruby Versions

The gem officially supports **Ruby 2.7 and newer**.

A note about Ruby 2.6: It works, but it requires activesupport to be set to a version less than 7 due to it dropping Ruby 2.6 support. Ruby 2.6 is no longer tested on CI.
The gem officially supports **Ruby 3.1 and newer**.

Any dropping of Ruby version support is considered a breaking change and means a major release for the gem.
