**Build powerful, extensible DSLs with exceptional developer experience**

Spark is a framework for creating declarative domain-specific languages in
Elixir. It transforms simple struct definitions into rich, extensible DSLs that
come with autocomplete, documentation generation, and sophisticated tooling
built right in.

## Quick Example

Here's how you can build a data validator DSL with Spark:

```elixir
defmodule MyApp.PersonValidator do
  use MyLibrary.Validator

fields do
    required [:name]
    field :name, :string

field :email, :string do
      check &String.contains?(&1, "@")
      transform &String.trim/1
    end
  end
end

MyApp.PersonValidator.validate(%{name: "Zach", email: " foo@example.com "})
{:ok, %{name: "Zach", email: "foo@example.com"}}
```

The DSL definition itself is clean and declarative:

```elixir
@field %Spark.Dsl.Entity{
  name: :field,
  args: [:name, :type],
  target: Field,
  describe: "A field that is accepted by the validator",
  schema: [
    name: [type: :atom, required: true, doc: "The name of the field"],
    type: [type: {:one_of, [:integer, :string]}, required: true, doc: "The type of the field"],
    check: [type: {:fun, 1}, doc: "A function to validate the value"],
    transform: [type: {:fun, 1}, doc: "A function to transform the value"]
  ]
}

@fields %Spark.Dsl.Section{
  name: :fields,
  entities: [@field],
  describe: "Configure the fields that are supported and required"
}

use Spark.Dsl.Extension, sections: [@fields]
```

## What You Get Out of the Box

* 🔧 **Extensible Architecture** - Anyone can write extensions for your DSL,
  making it infinitely customizable
* 🧠 **Smart Autocomplete** - Built-in ElixirSense integration provides
  intelligent code completion and inline documentation in your editor
* 📚 **Auto Documentation** - Generate comprehensive documentation for your DSL
  automatically, including all options and usage examples
* ⚡ **Developer Tools** - Mix tasks for formatting, code generation, and
  maintaining `locals_without_parens` automatically
* 🔄 **Compile-time Processing** - Use transformers to modify DSL structures
  during compilation and verifiers to validate correctness
* 🎯 **Type Safety** - Rich schema validation ensures DSL usage is correct at
  compile time with helpful error messages
* 🔍 **Introspection** - Built-in tools to inspect and query DSL definitions
  programmatically at runtime

## Installation

Add `spark` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:spark, "~> 2.3"}
  ]
end
```

## Getting Started

The best way to get started is with our comprehensive tutorial that walks you
through building a complete DSL from scratch:

📖 **[Get Started with Spark](documentation/tutorials/get-started-with-spark.md)** -
Build a data validator DSL step by step

### Quick Start Checklist

1. **Define your DSL structure** using `Spark.Dsl.Section` and `Spark.Dsl.Entity`
2. **Create your extension** with `use Spark.Dsl.Extension`
3. **Build your DSL module** that users will import
4. **Add transformers and verifiers** for advanced behavior
5. **Generate helper functions** with `Spark.InfoGenerator`

Each step is covered in detail in the tutorial above.

## Production Ready

Spark is battle-tested and powers all DSLs in the [Ash Framework](https://ash-hq.org),
handling complex real-world applications with thousands of DSL definitions.
Whether you're building configuration DSLs, workflow orchestrators, or
domain-specific languages for your business logic, Spark provides the foundation
for production-grade solutions.
