This code is a macro written in Jinja2, a powerful template engine for Python. This macro, named var_dump, works similarly to PHP's var_dump() function. It helps to print or display structured information about variables, especially useful for debugging.
The var_dump macro takes four parameters:
-
var
: The variable you want to display. -
var_name
: The name of the variable (this is optional, and its default value is an empty string). -
space
: The indentation level (this is optional, and its default value is 0).
