Usage of Drafter-php

1. Get an instance of the \DrafterPhp\DrafterInterface implementation, \DrafterPhp\Drafter 1.1 You will need to pass the path to your drafter binary to the constructor 1.2 It is recommended to solve this using a dependency injection container
2. Set the input file and options on your \DrafterPhp\Drafter instance 2.1 Drafter-php currently does not support passing blueprint code directly to Drafter; it has to be stored in a file at this time
3. Run your command

Input / Output Examples

Note: drafter-php does not assert the structure of the output. If you see differences in the examples to your actual output, please refer to the official drafter docs.

Given this api blueprint source:

# GET /message
+ Response 200 (text/plain)

        Hello World!

The result will look similar (json refract):

{
  "element": "parseResult",
  "content": [
    {
      "element": "category",
      "meta": {
        "classes": [

Code Examples

Found something wrong? Feel free to contribute

Make sure it works

To make sure it works, we'll ask Drafter for the current version.

$version = $drafter
    ->version()
    ->run();

// Reset options on the command
$drafter->resetOptions();

$version should now contain a string like v1.0.0. If something is wrong, an exception will have been thrown most likely.

Keep in mind that Drafter-php is designed to keep its state, run \DrafterPhp\DrafterInterface::resetOptions to get rid of the version option you just set for the next call on the instance.

Parse your-service.apib into your-service.refract.json

Make sure your input path is correct and readable, and your output path is writable.

$drafter
    ->input('your-service.apib')
    ->format('json')
    ->type('refract')
    ->output('your-service.refract.json')
    ->run();

Parse your-service.apib into your-service.ast.json

Make sure your input path is correct and readable, and your output path is writable.

$drafter
    ->input('your-service.apib')
    ->format('json')
    ->output('your-service.ast.json')
    ->run();

Parse your-service.apib into a PHP data structure

$refract = $drafter
    ->input('your-service.apib')
    ->format('json')
    ->run();
    
$phpObj = json_decode($refract);
$phpArr = json_decode($refract, true);

Parse your-service.apib into YAML format

$drafter
    ->input('your-service.apib')
    ->format('yaml') // optional as yaml is the default
    ->output('your-service.ast.yml')
    ->run();

Get Process before it is run

$process = $drafter
    ->input('your-service.apib')
    ->format('json')
    ->output('your-service.refract.json')
    ->build();

// do stuff with the process

$drafter
    ->run($process);

Feature Roadmap

Do not hesitate to contribute.

• support passing raw api blueprint code into \DrafterPhp\DrafterInterface::input, rather than always a file path
