Uses ParGlare for parsing, meant to work with CausticGrammar to create a CST (Caustic AST)
CLI usage
See cap --help
Module usage
import sys
import parglare
from pprint import pprint
from pathlib import Path
from caustic import parser
grammar = parglare.Grammar.from_file(parser.builtin_grammar('canonical/canonical.pg'))
# ^ builtin_grammar fetches the builtin grammar path from caustic.grammar,
# optionally adding a subdirectory and checking if it exists
parser_ = parglare.GLRParser(grammar, lexical_disambiguation=True,
actions=parser.actions.action.all)
# ^ the actions module supplies some generally useful actions,
# as well as actions specifically for creating CST nodes
try:
forest = parser_.parse(input())
except parglare.ParseError as e:
# custom error formatting
print(parser.errors.format_exc(e), file=sys.stderr)
cst = parser_.call_actions(forest.get_first_tree())
