Diviner Tech Docs PhabricatorMarkupEngine

final class PhabricatorMarkupEngine
Phorge Technical Documentation (Remarkup)

Manages markup engine selection, configuration, application, caching and pipelining.

PhabricatorMarkupEngine can be used to render objects which implement PhabricatorMarkupInterface in a batched, cache-aware way. For example, if you have a list of comments written in remarkup (and the objects implement the correct interface) you can render them by first building an engine and adding the fields with addObject().

$field  = 'field:body'; // Field you want to render. Each object exposes
                        // one or more fields of markup.

$engine = new PhabricatorMarkupEngine();
foreach ($comments as $comment) {
  $engine->addObject($comment, $field);
}

Now, call process() to perform the actual cache/rendering step. This is a heavyweight call which does batched data access and transforms the markup into output.

$engine->process();

Finally, do something with the results:

$results = array();
foreach ($comments as $comment) {
  $results[] = $engine->getOutput($comment, $field);
}

If you have a single object to render, you can use the convenience method renderOneObject().

Tasks

Markup Pipeline

  • public static function renderOneObject($object, $field, $viewer, $context_object) — Convenience method for pushing a single object through the markup pipeline.
  • public function addObject($object, $field) — Queue an object for markup generation when @{method:process} is called. You can retrieve the output later with @{method:getOutput}.
  • public function process() — Process objects queued with @{method:addObject}. You can then retrieve the output with @{method:getOutput}.
  • public function getOutput($object, $field) — Get the output of markup processing for a field queued with @{method:addObject}. Before you can call this method, you must call @{method:process}.
  • public function getEngineMetadata($object, $field, $metadata_key, $default) — Retrieve engine metadata for a given field.
  • private function requireKeyProcessed($key)
  • private function getMarkupFieldKey($object, $field)
  • private function loadPreprocessorCaches($engines, $objects)
  • public function setViewer($viewer) — Set the viewing user. Used to implement object permissions.
  • public function setContextObject($object) — Set the context object. Used to implement object permissions.
