Reading ipe Files
readRawIpeFile :: Coordinate r => FilePath -> IO (Either ConversionError (IpeFile r)) Source #
Given a file path, tries to read an ipe file
readIpeFile :: Coordinate r => FilePath -> IO (Either ConversionError (IpeFile r)) Source #
Given a file path, tries to read an ipe file. This function applies all matrices to objects.
readSinglePageFile :: Coordinate r => FilePath -> IO (Either ConversionError (IpePage r)) Source #
Since most Ipe file contain only one page, we provide a shortcut for that as well. This function applies all matrices.
type ConversionError = Text Source #
Reading XML directly
fromIpeXML :: IpeRead (t r) => ByteString -> Either ConversionError (t r) Source #
Given a Bytestring, try to parse the bytestring into anything that is IpeReadable, i.e. any of the Ipe elements.
readXML :: ByteString -> Either ConversionError (Node Text Text) Source #
Reads the data from a Bytestring into a proper Node

class IpeReadAttr t where Source #
Basically IpeReadText for attributes. This class is not really meant to be
implemented directly. Just define an IpeReadText instance for the type
(Apply f at), then the generic instance below takes care of looking up the
name of the attribute, and calling the right ipeReadText value. This class
is just so that reifyConstraint in ipeReadRec can select the right
typeclass when building the rec.

Methods
ipeReadAttr :: Text -> Node Text Text -> Either ConversionError t Source #
Instances
| IpeReadText (Apply u * f at) => IpeReadAttr (Attr u f at) Source # | |
Some low level implementation functions
ipeReadTextWith :: (Text -> Either t v) -> Text -> Either ConversionError (IpeValue v) Source #
ipeReadObject :: (IpeRead (i r), f ~ AttrMapSym1 r, ats ~ AttributesOf i, RecApplicative ats, RecAll (Attr f) ats IpeReadAttr, AllSatisfy IpeAttrName ats) => Proxy i -> proxy r -> Node Text Text -> Either ConversionError (i r :+ IpeAttributes i r) Source #
If we can ipeRead an ipe element, and we can ipeReadAttrs its attributes we can properly read an ipe object using ipeReadObject
ipeReadAttrs :: forall proxy proxy' i r f ats. (f ~ AttrMapSym1 r, ats ~ AttributesOf i, RecApplicative ats, RecAll (Attr f) ats IpeReadAttr, AllSatisfy IpeAttrName ats) => proxy i -> proxy' r -> Node Text Text -> Either ConversionError (IpeAttributes i r) Source #
Reader for records. Given a proxy of some ipe type i, and a proxy of an coordinate type r, read the IpeAttributes for i from the xml node.
ipeReadRec :: forall f ats. (RecApplicative ats, RecAll (Attr f) ats IpeReadAttr, AllSatisfy IpeAttrName ats) => Proxy f -> Proxy ats -> Node Text Text -> Either ConversionError (Rec (Attr f) ats) Source #
Reading the Attributes into a Rec (Attr f), all based on the types of f (the type family mapping labels to types), and a list of labels (ats).
