GLYPH Python

Python implementation of the GLYPH codec.

The primary surface is still codec-first:

• parse and emit values
• JSON bridge helpers
• canonicalization and fingerprinting
• streaming validation

Higher-level agent helpers exist, but they are optional layers on top of the codec.

Install

pip install glyph-py

Quick Start

import glyph

data = {"action": "search", "query": "weather", "max_results": 10}

text = glyph.json_to_glyph(data)
print(text)

restored = glyph.glyph_to_json(text)
assert restored == data

value = glyph.parse('{name=Alice age=30 active=t}')
print(value.get("name").as_str())
print(value.get("age").as_int())

fp = glyph.fingerprint_loose(glyph.from_json(data))
print(fp)

Core Functions

Building Values

from glyph import g, field

team = g.struct(
    "Team",
    field("name", g.str("Arsenal")),
    field("rank", g.int(1)),
)

print(glyph.emit(team))

Streaming Validation

from glyph import StreamingValidator, ToolRegistry

registry = ToolRegistry()
registry.add_tool("search", {
    "query": {"type": "str", "required": True},
    "max_results": {"type": "int", "min": 1, "max": 100},
})

validator = StreamingValidator(registry)

for token in 'search{query="glyph" max_results=5}':
    result = validator.push_token(token)

assert result.complete
assert result.valid
assert result.tool_name == "search"

Optional Higher-Level Layer

The Python package also contains an optional agent-oriented runtime in glyph.agent. Treat that as an example consumer of the codec layer, not the definition of the format.
