Projection that can render the state of the Event Sourced Content Repository into markwhen syntax

Warning This package mostly serves as demonstration on how to write a simple Event Sourced Content Repository projection It's probably not very useful in its current form, but feel free to copy and adjust it to your needs!

Usage

Installation

install via composer:

composer require wwwision/markwhen

Note At the time of writing, a couple of required packages are not yet available on packagist You can download those from GitHub to your distribution folder: https://github.com/neos/neos-development-collection/tree/9.0/Neos.ContentRepository.Core https://github.com/neos/neos-development-collection/tree/9.0/Neos.ContentRepositoryRegistry https://github.com/neos/neos-development-collection/tree/9.0/Neos.ContentGraph.DoctrineDbalAdapter https://github.com/neos/neos-development-collection/tree/9.0/Neos.ContentGraph.PostgreSQLAdapter and install everything via composer require wwwision/markwhen neos/contentrepositoryregistry:@dev neos/contentgraph-doctrinedbaladapter:@dev neos/contentgraph-postgresqladapter:@dev

Afterwards you can replay the projection to built up its initial state:

./flow cr:replay markwhen

Once the state is persisted, you can call

./flow markwhen:render

to turn it into markwhen syntax. This will output the result to the console output directly, but you can store it into a file with:

./flow markwhen:render > out.mw

With the help of the Markwhen CLI tool you can turn that into a timeline or calendar:

mw out.mv -d timeline.html 
mw out.mv -d calendar.html

Or pipe the output of the render command to mw directly:

./flow markwhen:render | mw /dev/stdin -d timeline.html

Files in this package

• MarkwhenCommandController.php: Flow CLI controller that provides the markwhen:* commands
• MarkwhenProjection.php: The actual Content Repository projection
• MarkwhenProjectionFactory.php: Simple factory for the projection that is configured with the Content Repository Registry
• MarkwhenProjectionState.php: PHP class that holds the state of the projection and can be turned into (and restored from) JSON
• Settings.yaml: Configuration for this package, registering the projection with the "default" Content Repository

Different Content Repository

This package registers the MarkwhenProjection with the default content repository. To register it to a different instance, you can adjust the settings accordingly:

Neos:
  ContentRepositoryRegistry:
    contentRepositories:
      'acme':
        projections:
          'Wwwision.Markwhen:Markwhen':
            factoryObjectName: Wwwision\Markwhen\MarkwhenProjectionFactory

Or you register it with a Content Repository preset so that it can be used in multiple CRs without additional configuration (see docs.neos.io:

Neos:
  ContentRepositoryRegistry:
    presets:
      'somePreset':
        projections:
          'Wwwision.Markwhen:Markwhen':
            factoryObjectName: Wwwision\Markwhen\MarkwhenProjectionFactory

Don't forget to specify the Content Repository ID for the commands:

./flow cr:replay markwhen --content-repository acme
./flow markwhen:render --content-repository acme
