Templating utilities

Sonotoria

Sonotoria is a library designed to provide features helping with templating and handling yaml files.

Loading Yaml

Sonotoria lets you load a yaml with variables using jinja2 syntax:

Examples

From a file

Given the file:

# test.yml
---

param: value
param2: {{ param }}

You can load the data:

>>> from sonotoria import yaml
>>> yaml.load('test.yml')
{'param': 'value', 'param2': 'value'}

From a string

You can also load a string directly:

>>> from sonotoria import yaml
>>> yaml.loads('---\nparam: value\nparam2: {{ param }}')
{'param': 'value', 'param2': 'value'}

Using filters

Given the file:

# test.yml
---

param: value
param2: {{ param | doubled }}

You can load the data:

>>> from sonotoria import yaml
>>> yaml.load('test.yml', filters={'doubled': lambda s: s*2})
{'param': 'value', 'param2': 'valuevalue'}

Using tests

Given the file:

# test.yml
---

param: value
param2: {{ param is number }}

You can load the data:

>>> from sonotoria import yaml
>>> yaml.load('test.yml', tests={'number': lambda s: s.isdigit()})
{'param': 'value', 'param2': False}

Using objects

Given the file:

# test.yml
--- !stuff

param: value
param2: {{ param }}

You can load the data:

>>> from sonotoria import yaml
>>> class Stuff:
....    pass
>>> my_stuff = yaml.load('test.yml', types={'stuff': Stuff})
>>> my_stuff.param
value
>>> my_stuff.param2
value

You can add tests, filters and types:

Extractor

Sonotoria lets you extract data from a file using a jinja2 template.

Example

Given this input file:

That is a description

:param test: Looks like a test variable, huh
:param lol: This might be a fun variable
:param plop: Plop might just be the next best variable name
:return: Pretty much nothing, sadly

And this template file:

{{ description }}

{% for param, desc in params.items() %}
:param {{ param }}: {{ desc }}
{% endfor %}{% if return_given %}
:return: {{ return }}{% endif %}{% if rtype_given %}
:rtype: {{ rtype }}{% endif %}

You can extract data this way:

>>> import sonotoria
>>> sonotoria.extract('template.file', 'input.file')
{
    'description': 'That is a description',
    'params': {
        'test': 'Looks like a test variable, huh',
        'lol': 'This might be a fun variable',
        'plop': 'Plop might just be the next best variable name'
    },
    'return': 'Pretty much nothing, sadly',
    'rtype': None,
    'return_given': True,
    'rtype_given': False
}
