Thorsten Buss 4d10db4f17 Initial public release
PHP 8.4 library and CLI tools to read, modify, and generate ProPresenter 7
files: songs (.pro), playlists (.proplaylist), bundles (.probundle), themes,
and the global library files (Macros, Labels, Groups, ClearGroups, CCLI,
Messages, Timers, Stage, Workspace, Props, TestPatterns, Calendar,
KeyMappings, CommunicationDevices).

Built on the MIT-licensed ProPresenter7-Proto schema by greyshirtguy
(v7.16.2). Includes 18 CLI parsers, comprehensive API docs in doc/,
binary-format specs, and a synthetic 369-test PHPUnit suite covering
RTF extraction, translation slides, ZIP64 repair, round-trip fidelity,
and end-to-end generation.

# TestPatterns Library API
> PHP module for reading and writing the global ProPresenter `TestPatterns` file
> (raw protobuf, no extension), including selected test-pattern state and saved
> pattern definitions.
## Quick Reference
```php
use ProPresenter\Parser\TestPatternsFileReader;
use ProPresenter\Parser\TestPatternsFileWriter;
$library = TestPatternsFileReader::read('/path/to/TestPatterns');
$library->getDisplayLocation(); // 3
$library->getSpecificScreenUuid(); // "BCDE1115-..."
$library->getPatterns(); // TestPatternData[]
TestPatternsFileWriter::write($library, '/path/to/TestPatterns');
```
---
## File Layout
The `TestPatterns` file is the protobuf-serialised
[`TestPatternDocument`](../../proto/testPattern.proto):
| Field | Type | Description |
|-------|------|-------------|
| `state` | `TestPatternDocument.TestPatternStateData` | Current test-pattern display state |
| `patterns` | repeated `TestPatternDocument.TestPatternData` | Saved pattern definitions |
`TestPatternStateData` includes selected pattern UUID/name, display location,
specific screen UUID, identify-screen flag, logo type, and optional user logo.
---
## Reading
```php
use ProPresenter\Parser\TestPatternsFileReader;
$library = TestPatternsFileReader::read('/Users/me/.../TestPatterns');
```
Throws `InvalidArgumentException` for missing files and `RuntimeException` for
empty / unreadable files.
---
## TestPatternsLibrary
Top-level wrapper around `Rv\Data\TestPatternDocument`. Indexes saved pattern
definitions by UUID (case-insensitive) and localization key.
```php
$library->getState();
$library->setState($stateOrNull);
$library->getSelectedPatternUuid();
$library->getSelectedPatternNameLocalizationKey();
$library->getDisplayLocation();
$library->getSpecificScreenUuid();
$library->getPatterns();
$library->count();
$library->getPatternByUuid('...');
$library->getPatternByName('Test Pattern');
$library->addPattern('Test Pattern', 'UUID');
$library->removePattern('UUID');
$library->getDocument(); // \Rv\Data\TestPatternDocument
```
---
## CLI Tool
```bash
php bin/parse-test-patterns.php /path/to/TestPatterns
```
Output:
```
TestPatterns (0):
State: selected=(none) :: name=(none) :: display_location=3 :: screen=BCDE1115-AD40-4BA4-A33A-BFFE3E87223B
```
---
## Key Files
| File | Purpose |
|------|---------|
| `src/TestPatternsLibrary.php` | Document-level wrapper with state accessors |
| `src/TestPatternsFileReader.php` | Reads the `TestPatterns` file |
| `src/TestPatternsFileWriter.php` | Writes the `TestPatterns` file |
| `bin/parse-test-patterns.php` | CLI tool |
| `proto/testPattern.proto` | Protobuf schema |
| `generated/Rv/Data/TestPatternDocument.php` | Generated message class |
---
## Scope Notes
The wrapper exposes `TestPatternData` and `TestPatternStateData` protobufs
directly. It does not render test patterns or interpret nested property oneofs.
