%model magic adds Macro definition to SQL

[eakmanrq]

Repro:
Macro:

from sqlglot import expressions as exp

from sqlmesh.core.macros import macro, MacroEvaluator


@macro()
def test_macro(
    evaluator: MacroEvaluator,
    column: exp.Column,
) -> exp.Expression:
    return column

Model:

MODEL (
  name db.test,
);

SELECT
  @test_macro(cola),
  ds AS ds
FROM tb

Output:

MODEL (
  name db.test,
  kind INCREMENTAL_BY_TIME_RANGE (
    time_column (ds, '%Y-%m-%d')
  ),
  dialect duckdb
);

def test_macro(evaluator, column):
    return column;

SELECT
  @test_macro(cola) AS test_macro,
  ds AS ds
FROM tb
