With pip

Usage

This module allows document generation from template files using the jinja2 rendering engine.

To be usable, template files must be located in the directory defined by the base_path parameter passed to the template.Renderer object.

To handle variable interpolation, the template file MUST accept a dictionary named params as a parameter.

This dictionary must contain all the variables necessary for the complete rendering of the template file.

The rendering of the template file is obtained from the template.Renderer object, whose instantiation requires the name of a template file and the base path in which to search for the template file.

Environment-specific parameters for Jinja2 can be modified through the env attribute of the template.Renderer object.

By convention, the template files used by the Scrippy framework are stored in the directory defined by the env::templatedirdir configuration parameter (see the configuration of the Scrippy framework in the relevant documentation).

A template is a simple text file with certain duly marked passages interpolated by the variables passed as parameters.

The Renderer.render() method returns the rendering of the template file.

The variables must be supplied to the template file as a dictionary named params.

The dictionary will be passed to the template file which will be responsible for interpolating the variables it contains.

Template files can include:

• control structures
• loops

Simple template file

With the following template file named template_test.mod located in the directory /var/scrippy/templates:

Hello {{params.user}}

You received this email because you are a member of the functional administrators of {{params.app}}.

The {{params.script}} script execution on {{params.date}} ended with the following error code:
- {{params.error.code}}: {{params.error.msg}}

--
Regards.
{{params.sender}}

The template file can be used as follows:

import datetime
from scrippy_template import template

params = {"user": "Harry Fink",
          "app": "Flying Circus",
          "script": "dead_parrot.py",
          "date": datetime.datetime.now().strftime("%Y/%m/%d"),
          "error": {"code": 42,
                    "msg": "It’s not pinin’! It’s passed on! This parrot is no more!"},
          "sender": "Luiggi Vercotti", }

base_path = '/var/lib/scrippy/templates'
template_file = 'template.j2'
renderer = template.Renderer(base_path, template_file)

print(renderer.render(params))

With the default values, the message displayed at the end of the script will contain:

Hello Harry Fink

The  dead_parrot.py script execution on 2019/09/15 ended with the following error code:

Template file with control structures

params = {"user": "Harry Fink",
          "app": "Flying Circus",
          "script": "dead_parrot.py",
          "date": datetime.datetime.now().strftime("%Y/%m/%d"),
          "num_error": 42,
          "sender": "Luiggi Vercotti", }

Hello {{params.user}}

You received this email because you are a member of the functional administrators of {{params.app}}.

The {{params.script}} script execution on {{params.date}} ended
{% if params.num_errors == 0 %}
- without error
{% else %}
 with {{params.num_errors}} error(s)
{% endif %}

Template file with loop

          "date": datetime.datetime.now().strftime("%Y/%m/%d"),
          'errors': [{'code': 2, 'msg': "It's not pinin’! It's passed on! This parrot is no more!"},
                     {'code': 3, 'msg': "Ohh! The cat's eaten it."}],
          "sender": "Luiggi Vercotti", }

Hello {{params.user}}

You received this email because you are a member of the functional administrators of {{params.app}}.
