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.

public function getPhobjectClassConstant($key, $byte_limit)
Inherited

Phobject

Read the value of a class constant.

This is the same as just typing self::CONSTANTNAME, but throws a more useful message if the constant is not defined and allows the constant to be limited to a maximum length.

Parameters
string$keyName of the constant.
int|null$byte_limitMaximum number of bytes permitted in the value.
Return
stringValue of the constant.

public static function renderOneObject($object, $field, $viewer, $context_object)

Convenience method for pushing a single object through the markup pipeline.

Parameters
PhabricatorMarkupInterface$objectThe object to render.
string$fieldThe field to render.
PhabricatorUser$viewerUser viewing the markup.
object$context_objectA context object for policy checks
Return
stringMarked up output.

public function addObject($object, $field)

Queue an object for markup generation when process() is called. You can retrieve the output later with getOutput().

Parameters
PhabricatorMarkupInterface$objectThe object to render.
string$fieldThe field to render.
Return
this

public function process()

Process objects queued with addObject(). You can then retrieve the output with getOutput().

Return
this

public static function isRenderingEmbeddedContent()

Return
wild

private function execute()

Return
wild

public function getOutput($object, $field)

Get the output of markup processing for a field queued with addObject(). Before you can call this method, you must call process().

Parameters
PhabricatorMarkupInterface$objectThe object to retrieve.
string$fieldThe field to retrieve.
Return
stringProcessed output.

public function getEngineMetadata($object, $field, $metadata_key, $default)

Retrieve engine metadata for a given field.

Parameters
