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.

# KeyMappings Library API
> PHP module for reading and writing the global ProPresenter `KeyMappings` file
> (raw protobuf, no extension) and exposing configured hot-key mappings.
## Quick Reference
```php
use ProPresenter\Parser\KeyMappingsFileReader;
use ProPresenter\Parser\KeyMappingsFileWriter;
$library = KeyMappingsFileReader::read('/path/to/KeyMappings');
foreach ($library->getMappings() as $mapping) {
$mapping->getName(); // string
$mapping->getUuid(); // string
$mapping->getHotKey(); // ?\Rv\Data\HotKey
$mapping->getTarget(); // raw bytes
}
KeyMappingsFileWriter::write($library, '/path/to/KeyMappings');
```
---
## File Layout
The `KeyMappings` file is the protobuf-serialised
[`KeyMappingsDocument`](../../proto/keyMappings.proto):
| Field | Type | Description |
|-------|------|-------------|
| `application_info` | `ApplicationInfo` | ProPresenter writer metadata |
| `mappings` | repeated `KeyMappingsDocument.Mapping` | Configured key bindings |
Each `Mapping` carries:
| Field | Type | Description |
|-------|------|-------------|
| `uuid` | `UUID` | Optional stable mapping identifier |
| `hot_key` | `HotKey` | Key combo that fires the action |
| `target` | bytes | Raw target reference |
| `name` | string | Optional display name |
---
## Reading
```php
use ProPresenter\Parser\KeyMappingsFileReader;
$library = KeyMappingsFileReader::read('/Users/me/.../KeyMappings');
```
Throws `InvalidArgumentException` for missing files and `RuntimeException` for
empty / unreadable files.
---
## KeyMappingsLibrary
Top-level wrapper around `Rv\Data\KeyMappingsDocument`. Indexes mappings by UUID
(case-insensitive) and name.
```php
$library->getMappings();
$library->count();
$library->getMappingByUuid('...');
$library->getMappingByName('Macro trigger');
$library->addMapping('Macro trigger', 'UUID', $targetBytes);
$library->removeMapping('UUID');
$library->getApplicationInfo();
$library->setApplicationInfo($infoOrNull);
$library->getDocument(); // \Rv\Data\KeyMappingsDocument
```
---
## KeyMapping
```php
$mapping->getName();
$mapping->setName('New Name');
$mapping->getUuid();
$mapping->setUuid('...');
$mapping->getHotKey();
$mapping->setHotKey($hotKeyOrNull);
$mapping->getTarget();
$mapping->setTarget($bytes);
$mapping->getProto(); // \Rv\Data\KeyMappingsDocument\Mapping
```
Targets are raw bytes because ProPresenter may encode several internal target
types here. Keeping bytes opaque preserves round-trip safety.
---
## CLI Tool
```bash
php bin/parse-key-mappings.php /path/to/KeyMappings
```
Output for the reference sample:
```
KeyMappings (0):
```

## Key Files
| File | Purpose |
|------|---------|
| `src/KeyMappingsLibrary.php` | Document-level wrapper with UUID/name lookups |
| `src/KeyMapping.php` | Single mapping wrapper |
| `src/KeyMappingsFileReader.php` | Reads the `KeyMappings` file |
| `src/KeyMappingsFileWriter.php` | Writes the `KeyMappings` file |
| `bin/parse-key-mappings.php` | CLI tool |
| `proto/keyMappings.proto` | Protobuf schema |
| `generated/Rv/Data/KeyMappingsDocument.php` | Generated message class |
---
## Scope Notes
The reference sample contains only `ApplicationInfo` and no mappings. The API
still supports mapping additions/removals so configured user files can be edited
and round-tripped safely.
