Khepri-parse
Parser and lexer for the Khepri programming language.
A library of Bennu parsers.
Usage
The main high level library interface is the lex
and parse
functions:
with
import 'khepri-parse::lex::lexer' {lex},
import 'khepri-parse::parse::parser' {parseStream}
{
// `lex` takes a character array and produces a token Nu stream.
// `parseStream` takes a lazy stream of tokens and outputs an AST.
"\x -> x;"
|> lex
|> parseStream;
}
Individual Bennu parses may also be consumed:
with
import 'khepri-parse::lex::number_lexer' {numericLiteral},
import 'bennu::parse' {many run}
{
var program := many numericLiteral;
run(program, "1 2e3 3.03");
}
