Parsing-primitives-seq
Some basic ABNF parsing functions for use with Seq.
These functions may be useful when writing
Seq-based parsers for languages specified via ABNF grammars.
These functions take lists of natural numbers as inputs
and return outputs of the form prescribed for Seq actions.
These parsing functions are somewhat similar to the fty::defresult-based parsing primitives, but they have an interface suitable for Seq
instead of an interface suitable for fty::defresult.
These parsing functions are being moved here
from the ABNF grammar parser:
they are used by the ABNF grammar parser,
but they are more general.
Subtopics
- Parse-exact-list
- Parse zero or more given natural numbers
into a tree that matches
a direct numeric value notation
that consists of that list of numbers.
- Parse-in-range
- Parse a natural number in a given range
into a tree that matches
a range numeric value notation that consists of that range.
- Parse-exact
- Parse a given natural number
into a tree that matches
a direct numeric value notation that consists of that number.
- Parse-any
- Parse any natural number.
