xwsyntax 0.6.0.24

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

xwsyntax

Bidirectional grammars: parse text to an AST, emit text again, or hop formats by reusing the same tree (for example JSON in, SQL out). 100+ grammars (300+ files) covering query languages, data formats, and code. Used by xwquery and editor/Monaco flows.

📦 Install

pip install exonware-xwsyntax
pip install exonware-xwsyntax[lazy]
pip install exonware-xwsyntax[full]

Runtime deps are declared in pyproject.toml (lark, exonware-xwsystem, exonware-xwnode, exonware-xwlazy wiring). See docs/GUIDE_01_USAGE.md for modes and troubleshooting.

🚀 Quick start

from exonware.xwsyntax import BidirectionalGrammar

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

sql_grammar = BidirectionalGrammar.load('sql')
sql = sql_grammar.generate(ast)

Facade: XWSyntax().parse(text, format_name) or validate(text, format_name).
Discovery: list_grammars_quick(), load_grammar_quick(name).
More code paths: REF_14_DX, API: REF_15_API.

📄 Examples

Facade parse/validate

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 and load grammars

from exonware.xwsyntax import list_grammars_quick, load_grammar_quick

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

JSON to SQL via shared 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	Contents
Read/write	Grammar-driven parse and generate; avoid hand-maintained per-format maps.
Bidirectional	Round-trip or cross-syntax by swapping grammars on the same AST.
Large grammar set	SQL, Cypher, GraphQL, xwqueryscript, configs, programming languages, markup, storage dialects; 300+ .lark / .json assets.
Downstream	xwquery parsing; Monaco export and codec hooks via xwsystem.

Phase: Alpha. Milestones: REF_22_PROJECT.

⏱️ Async Support

• xwsyntax is primarily synchronous in its current implementation.
• Source validation: 0 async def definitions and 0 await usages under src/.
• This module still composes with async-capable xw libraries at integration boundaries when needed.
