style(+StyleIn) is semidet[multifile, wordlist(highlight)]

style(+StyleIn, -SWISHType:atomOrPair, -Attributes:list)[multifile, wordlist(highlight)]

Declare that we map StyleIn as generated by library(prolog_colour) into a token of type SWISHType, providing additional context information based on Attributes. Elements of Attributes are terms of the form Name(Value) or the atom text. The latter is mapped to text(String), where String contains the text that matches the token character range.

The resulting JSON token object has a property type, containing the SWISHType and the properties defined by Attributes.

Additional translations can be defined by adding rules for the multifile predicate style/3. The base type, which refers to the type generated by the SWISH tokenizer must be specified by adding an attribute base(BaseType). For example, if the colour system classifies an atom as refering to a database column, library(prolog_colour) may emit db_column(Name) and the following rule should ensure consistent mapping:

swish_highlight:style(db_column(Name),
                      db_column, [text, base(atom)]).
