debug

Overview

The {{ debug() }} macro will open an iPython debugger in the context of a compiled dbt macro. The DBT_MACRO_DEBUGGING environment value must be set to use the debugger.

Usage

my_macro.sql
{% macro my_macro() %}
{% set something_complex = my_complicated_macro() %}
{{ debug() }}
{% endmacro %}

When dbt hits the debug() line, you'll see something like:

$ DBT_MACRO_DEBUGGING=write dbt compile
