pyfcstm.dsl

pyfcstm DSL package initialization and public API exports.

This package aggregates the public interface for the pyfcstm domain-specific language (DSL). It re-exports parser entry points, grammar nodes, error types, and the parse tree listener so users can import them directly from pyfcstm.dsl.

The module exposes the following public components:

GrammarParseListener - Parse tree listener that builds AST nodes from the grammar.
parse_condition() - Parse a conditional expression.
parse_preamble() - Parse a preamble program.
parse_operation() - Parse an operation program.
parse_with_grammar_entry() - Parse using a specific grammar rule entry.
Error classes from pyfcstm.dsl.error, including GrammarParseError and GrammarItemError.

The grammar nodes and parser definitions are re-exported via pyfcstm.dsl.grammar and pyfcstm.dsl.node.

Example:

>>> from pyfcstm.dsl import parse_condition, GrammarParseError
>>> try:
...     node = parse_condition("x > 1 && y < 3")
... except GrammarParseError as exc:
...     print(exc)
