Properties

attr

the common portion of the attribute

getAttrFontFeaturesAttr :: MonadIO m => AttrFontFeatures -> m Attribute

Get the value of the “attr” field. When overloading is enabled, this is equivalent to

get attrFontFeatures #attr

features

the featues, as a string in CSS syntax

clearAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> m ()

Set the value of the “features” field to Nothing. When overloading is enabled, this is equivalent to

clear #features

getAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> m (Maybe Text)

Get the value of the “features” field. When overloading is enabled, this is equivalent to

get attrFontFeatures #features

setAttrFontFeaturesFeatures :: MonadIO m => AttrFontFeatures -> CString -> m ()

Set the value of the “features” field. When overloading is enabled, this is equivalent to

set attrFontFeatures [ #features := value ]
