# Create different documents from the same sources using Jinja

> **Note: Specialist technique**
>
> This tutorial applies build-time conditional text (profiling) to a reStructuredText toolchain, using a Python preprocessing script. The principle, generating several document variants from one source, applies to other formats; for DITA XML's equivalent, see the [NuFirewall case study](https://docs.redaction-technique.org/en/formats/nufirewall-case-study/).

## Objective

The `profiling.py` Python script below allows you to profile content in *preprocessing* using the powerful Jinja template engine. For a more complex variant using object-oriented classes, see [creating different documents via Jinja (object method)](https://docs.redaction-technique.org/en/tutorials/conditional-text-jinja-object-method/). You can also generate documents [directly from ReST conditional text](https://docs.redaction-technique.org/en/tutorials/conditional-text-sphinx-rest/) without a separate preprocessing step.

```python
#!/usr/bin/env python3
import jinja2
import sys

public=str(sys.argv[1])
env = jinja2.Environment(loader=jinja2.FileSystemLoader('./'))
template = env.get_template('conditional-text.rst')
string=template.render(audience=public)

file = open('conditional-text-output.rst','w')
file.write(string)
file.close()
```

Contents of the file `conditional-text.rst`:

```txt
Using conditional text
=================================

{% if audience=='electrician' %}

.. admonition:: Danger for electricians

   Risk of electrocution

   Do not touch electrical wires.

{% else %}

.. admonition:: Danger for plumbers

   Risk of drowning

   Do not dive into the pool.

{% endif %}
```

How to use:

```bash
./profiling.py electrician
```

Now, just call the script before compiling *via* Sphinx in the `Makefile`.
