Generic TypeFieldVariable Annotation
As per Michelson documentation, this type has an invariant:
(except for the first character, here parametrized in the type tag) the
allowed character set is the one matching the following regexp:
%|%%|%|[:%][_0-9a-zA-Z][_0-9a-zA-Z.%@]*

pattern Annotation :: Text -> Annotation tag Source #
pattern WithAnn :: Annotation tag -> Annotation tag Source #
Annotation Set
data AnnotationSet Source #
An AnnotationSet contains all the typefieldvariable Annotations
, with each group in order, associated with an entity.
Note that in its rendering/show instances the unnecessary annotations will be
omitted, as well as in some of the functions operating with it.
Necessary Annotations are the ones strictly required for a consistent
representation.
In particular, for each group (tfv):
- if all annotations are noAnn they are all omitted
- if one or more noAnn follow a non-empty ann, they are omitted
- if one or more noAnn precede a non-empty ann, they are kept
- every non-empty ann is obviously kept
This is why order for each group is important as well as separation of
different groups of Annotations.
Instances
emptyAnnSet :: AnnotationSet Source #
An AnnotationSet without any Annotation.
fullAnnSet :: [TypeAnn] -> [FieldAnn] -> [VarAnn] -> AnnotationSet Source #
An AnnotationSet built from all 3 kinds of Annotation.
isNoAnnSet :: AnnotationSet -> Bool Source #
Returns True if all Annotations in the Set are unnecessaryemptynoAnn.
False otherwise.
minAnnSetSize :: AnnotationSet -> Int Source #
Returns the amount of Annotations that are necessary for a consistent
representation. See AnnotationSet.
singleAnnSet :: forall tag. KnownAnnTag tag => Annotation tag -> AnnotationSet Source #
An AnnotationSet with only a single Annotation (of any kind).
singleGroupAnnSet :: forall tag. KnownAnnTag tag => [Annotation tag] -> AnnotationSet Source #
An AnnotationSet with several Annotations of the same kind.

Creation and conversions
noAnn :: Annotation a Source #
ann :: HasCallStack => Text -> Annotation a Source #
Makes an Annotation from its textual value, prefix (%@:) excluded
Throws an error if the given Text contains invalid characters
mkAnnotation :: Text -> Either Text (Annotation a) Source #
Makes an Annotation from its textual value, prefix (%@:) excluded
Returns a Text error message if the given Text contains invalid characters
specialVarAnns :: [Text] Source #
List of all the special Variable Annotations, only allowed in CAR and CDR
instructions, prefix (@) excluded.
These do not respect the rules of isValidAnnStart and isValidAnnBodyChar.
specialFieldAnn :: Text Source #
The only special Field Annotation, only allowed in PAIR, LEFT and
RIGHT instructions, prefix (%) excluded.
This does not respect the rules of isValidAnnStart and isValidAnnBodyChar.
isValidAnnStart :: Char -> Bool Source #
Checks if a Char is valid to be the first of an annotation, prefix
(%@:) excluded, the ones following should be checked with
isValidAnnBodyChar instead.
Note that this does not check Special Annotations, see specialVarAnns
and specialFieldAnn
isValidAnnBodyChar :: Char -> Bool Source #
Checks if a Char is valid to be part of an annotation, following a valid
first character (see isValidAnnStart) and the prefix (%@:).
Note that this does not check Special Annotations, see specialVarAnns
and specialFieldAnn
unifyAnn :: Annotation tag -> Annotation tag -> Maybe (Annotation tag) Source #
ifAnnUnified :: Annotation tag -> Annotation tag -> Bool Source #
convAnn :: Annotation tag1 -> Annotation tag2 Source #
