Items with Metadata
class HasMetadata t where Source #
Instances
properties :: HasMetadata m => Lens' m (Set Key) Source #
Fetch all properties from items which contain metadata.
settings :: HasMetadata m => Lens' m (Assoc Key Text) Source #
Fetch all settings defined on items which contain metadata.
hasProperty :: HasMetadata m => Key -> Lens' m Bool Source #
atSetting :: HasMetadata m => Key -> Lens' m (Maybe Text) Source #
Select a setting from an item attached to metadata. Returns Nothing
if
no value is set.
Items wrapping content
class HasContent t where Source #
An optic for selecting children of an item in a recursive structure.
Instances
Accessors for fields not otherwise covered
Conversion between Tag
s and Region
s.
Prisms on Block
contexts
_BlockLiteral :: Prism' Block LiteralTag Source #
Focus only on literal tags.
_BlockParagraph :: Prism' Block Paragraph Source #
Focus only on paragraphs'
Prisms on Inline
contexts
_InlineTag :: Prism' Inline InlineTag Source #
Focus only on inline tags.
Optics on common types
_NonEmpty :: Prism' (Series a) (SeriesNE a) Source #
A prism between possibly-empty and non-empty containers.
