Language.Symantic.Grammar.EBNF

Type EBNF

newtype EBNF a

Extended Backus-Naur-Form, following the ISO-IEC-14977 notations, augmented with the following notations:

• ("U+", code_point): for ISO-IEC-10646 (aka. Unicode).
• (char, "…", char): for character range.
• (rule, "&", rule): for the intersection.
• (rule, "-", rule): for the difference.
• (rule, " ", rule): for rule application.

Inherited attributes are:

• RuleMode is the requested rendering mode of a Rule (body or reference).
• Infix and Side are the properties of the parent operator, used to enclose the operand in parenthesis only when needed.

Synthetized attributes are:

• Text of the EBNF rendition.
