xwsyntax 0.6.0.9

Convenience wrapper for exonware-xwsyntax - provides 'import xwsyntax' alias

xwsyntax

One bidirectional grammar engine. Parse text to AST, generate back, or convert between syntaxes (e.g. JSON to SQL). 100+ grammars (328+ files) for query, data, and code. Powers xwquery and editors; use it to create new syntaxes or bridge formats.

Install

pip install exonware-xwsyntax
# Optional: full extras
pip install exonware-xwsyntax[full]

Depends on xwsystem. See docs/GUIDE_01_USAGE.md for details.

Quick start

from exonware.xwsyntax import BidirectionalGrammar

grammar = BidirectionalGrammar.load('json')
ast = grammar.parse('{"name": "Alice", "age": 30}')
json_str = grammar.generate(ast)

# Convert between syntaxes
sql_grammar = BidirectionalGrammar.load('sql')
sql = sql_grammar.generate(ast)
# Same AST, different format

Facade: XWSyntax().parse(text, format_name) or validate(text, format_name).
List grammars: list_grammars_quick(), load_grammar_quick(name).
Key code: REF_14_DX · API: REF_15_API.

Examples

Parse and validate with the facade

from exonware.xwsyntax import XWSyntax

engine = XWSyntax()
ast = engine.parse("a = 1 + 2", format_name="python")
is_valid = engine.validate("a = 1 + 2", format_name="python")

List grammars and load by name

from exonware.xwsyntax import list_grammars_quick, load_grammar_quick

names = list_grammars_quick()
grammar = load_grammar_quick(names[0])

Convert JSON to SQL by reusing the AST

from exonware.xwsyntax import BidirectionalGrammar

ast = BidirectionalGrammar.load("json").parse('{"name": "Alice", "age": 30}')
sql = BidirectionalGrammar.load("sql").generate(ast)

What you get

Area	Description
Grammar read/write	Parse input to native objects or tree; generate from AST. Grammar-driven; no hardcoded format maps.
Bidirectional	Parse to AST, generate back; convert between syntaxes (e.g. JSON to SQL) by swapping grammars.
100+ grammars	Query (SQL, Cypher, GraphQL, xwqueryscript, …), data/config, programming, markup, storage. 328+ grammar files (.lark + .json).
xwquery and IDE	Parsing and syntax for query languages; Monaco export and codec integration with xwsystem.

Current phase: Alpha. M1–M2 done; xwquery consumption next. Status: REF_22_PROJECT.
