Thorsten Bus 9e3e719806 feat(library): add readers + writers for all ProPresenter global libraries and theme bundles
Add full IO support for every global ProPresenter library file plus
theme folders, and extend the existing Labels/Macros readers with
exporters and editable accessors so every supported document is now a
round-trippable, mutable object.

New library readers/writers (each: FileReader, FileWriter, Library
wrapper, element wrapper where applicable, CLI tool, tests, doc/api/*.md):

- Groups          (ProGroupsDocument)        + GroupDefinition
- ClearGroups     (ClearGroupsDocument)      + ClearGroupDefinition
- CCLI            (CCLIDocument)
- Messages        (MessageDocument)          + Message
- Timers          (TimersDocument + Clock)   + Timer
- Stage           (Stage.Document)           + StageLayout
- Workspace       (ProPresenterWorkspace)    + Screen
- Props           (PropDocument)             + Prop
- TestPatterns    (TestPatternDocument)
- Calendar        (new CalendarDocument)     + CalendarEvent
- KeyMappings     (new KeyMappingsDocument)  + KeyMapping
- CommunicationDevices (JSON file)           + CommunicationDevice
- Theme bundles   (Template.Document folder + Assets/) + ThemeBundle/Slide/Asset

Extensions to existing modules:

- LabelsFileWriter; Label and LabelLibrary gain setters, addLabel,
  removeLabel, setColor / setColorHex helpers
- MacrosFileWriter; Macro/MacroCollection/MacroLibrary gain UUID, name,
  color, image_type, image_data, trigger_on_startup setters plus
  add/remove for macros and collections

Two new minimal proto schemas were defined for documents that lacked
upstream definitions:

- proto/calendar.proto   - CalendarDocument with Event entries, raw
  bytes for the action/macro sub-messages so the schema can evolve
- proto/keyMappings.proto - KeyMappingsDocument with ApplicationInfo
  and a forward-looking Mapping message (sample only carries the info)

The Theme file turned out to be a regular Rv\Data\Template\Document, so
no new proto was required for theme content; ThemeBundle layers folder
+ Assets/ handling on top in the same spirit as PresentationBundle.

GroupDefinition is intentionally distinct from the existing Group class
(which wraps song-level CueGroup) to avoid breaking song APIs.

Verified with the full PHPUnit suite: 370 tests, 9200 assertions, all
green; LSP diagnostics clean across src/. The unmodified reference
samples for Labels, Groups, ClearGroups, TestPatterns, Calendar and
KeyMappings round-trip byte-for-byte; the others round-trip with the
same byte length (PHP protobuf is not canonically deterministic but
re-write-after-write stabilises).

doc/INDEX.md, doc/keywords.md and AGENTS.md updated so every new module
is discoverable from the top level.

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

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:

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

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.

$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

$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

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.
