FEATURE: Arrays of Tables Ordering

Purpose

The parser enforces TOML 1.0.0 ordering and conflict rules for arrays of tables.

Behavior

• A child table or child array cannot precede creation of its parent array element.
• A statically defined array cannot later be extended with an array-of-table header.
• An array of tables cannot be redefined as a normal table.
• A normal table cannot be redefined as an array of tables.
• Conflicting nested table and array-of-table declarations are rejected.
• Invalid documents produce a non-zero decoder exit status.

Programmatic Acceptance

Requires: executable=go; scope=test
Requires: executable=sh; scope=test

=== AC arrays-of-tables-ordering-conformance ===
Intent: The implementation rejects the authoritative invalid table-ordering and conflict cases.
Suite: scoped

import os import subprocess import sys

result = subprocess.run( ["sh", "sources/stage_test.sh", "invalid/table/*"], capture_output=True, text=True, env={**os.environ, "TOML_TEST_VERSION": "v2.2.0"}, ) print(result.stdout) print(result.stderr, file=sys.stderr) assert result.returncode == 0 === END AC arrays-of-tables-ordering-conformance ===

=== AC arrays-of-tables-ordering-exit ===
Intent: An invalid array-of-table ordering document exits unsuccessfully.

source = "[fruit.physical]\ncolor = \"red\"\n[[fruit]]\nname = \"apple\"\n" result = subprocess.run( ["go", "run", "./cmd/toml-decoder"], input=source, capture_output=True, text=True, ) assert result.returncode != 0 === END AC arrays-of-tables-ordering-exit ===

User Acceptance

• None.

Guardrails

• The parser rejects invalid ordering rather than assigning ambiguous parent elements.
• The parser does not silently reinterpret conflicting table kinds.
