Parser for simple entity definition file.
Definition file example:
const unitNamespace = "app\data";
const unitDir = "blog";
const unitName = "BlogDbContext";
@PK type UserId int;
@PK type CommentId int;
@PK type PostId int;
@Unique
type Email string(100);
type ShortString string(100);
type LongString string(500);
type DateModified date;
type DateCreated date;
type PasswordHash string(100);
entity User {
UserId Id;
ShortString FirstName;
ShortString LastName;
Email Email;
ShortString UserName;
ShortString PasswordHash;
DateModified Modified;
DateCreated Created;
}
entity Comment {
CommentId Id;
UserId UserId;
PostId PostId;
Text Text;
DateModified Modified;
DateCreated Created;
}
entity Post {
PostId Id;
UserId UserId;
ShortString Title;
Text Content;
DateModified Modified;
DateCreated Created;
}
Following snipet demonstrates how to load definition file.
<?php
include __DIR__ . "/vendor/autoload.php";
use EntityParser\Parser\Parser;
use EntityParser\Parser\Contract\CodeModelInterface;
$parser = new Parser();
$codeModel = $parser->parse(file_get_contents("Blog.edf"));
/**
* @var CodeModelInterface $codeModel
*/
$entities = $codeModel->getEntities();
$types = $codeModel->getTypes();
$constants = $codeModel->getConstants();
