RegexBuilder Package
====================

[](#regexbuilder-package)

A dev-only regex tester for NeoPHP. Write a pattern, test it against sample text, and see matches highlighted live — entirely client-side, no server round-trip needed to evaluate a match.

Dev-only, by design
-------------------

[](#dev-only-by-design)

The standalone page's route is protected by `DevOnlyMiddleware`, which checks `Config/app.config.php`'s `environment` key. Outside `environment: dev`, it returns a blocked response.

The `RegexBuilder` macro itself has no such restriction, since it makes no server calls — if you embed it in your own page (e.g. inside `neo-admin-package`), guard that page the same way you'd guard any other dev tool page in your project.

---

Installation
------------

[](#installation)

```
php bin/neo package:require neophp/regexbuilder-package --project=MyProject
```

Register it in the project's `Config/app.config.php`:

```
return [
    // ...
    'packages' => [
        \Vendor\NeoPHP\RegexBuilderPackage\NeoRegexBuilderPackage::class,
    ],
];
```

No configuration file, no migration.

---

Usage
-----

[](#usage)

### Standalone page

[](#standalone-page)

Visit `/_regexbuilder/` (only reachable in `dev`). Type a pattern and flags, edit the test string, and matches highlight live below.

### Embedding in your own page

[](#embedding-in-your-own-page)

```
{% import '@RegexBuilder/components/RegexBuilder.macro.html.twig' as RegexBuilder %}

{{ RegexBuilder.render() }}

```

`RegexBuilder.render(instanceId = 'rb')` accepts an optional `instanceId` to avoid collisions if rendered more than once on the same page.

---

PHP vs JavaScript regex differences
-----------------------------------

[](#php-vs-javascript-regex-differences)

This package uses JavaScript's native `RegExp`, not PHP's PCRE (`preg_match`). The two dialects are very similar for everyday patterns, but not identical — some PCRE-specific syntax (certain lookbehind variations, possessive quantifiers, recursive patterns) is not supported by JavaScript's engine. A pattern that behaves correctly here should work in PHP for the vast majority of common cases, but always verify directly in your PHP code for anything advanced.

---

Theming
-------

[](#theming)

Every visual value is a CSS custom property scoped to `.rb-layout`:

```
.rb-layout {
    --rb-accent: #6366f1;
    --rb-bg: #161923;
    --rb-bg-alt: #1b2030;
    --rb-border: #2d3342;
    --rb-text: #e5e7eb;
    --rb-text-muted: #9ca3af;
    --rb-mark-bg: #fbbf24;
}
```
