Buildout recipe for making files out of Jinja2 templates

Project description

brodul.recipe.template is a fork of amplecode.recipe.template, a Buildout recipe for generating files using Jinja2 templates. The recipe configures a Jinja2 environment, by default relative to the Buildout directory, allowing templates to extend and include other templates relative to the environment.

Downloads are available from pypi: http://pypi.python.org/pypi/brodul.recipe.template/

Buildout Options

  • template-file or input (required): One or more Jinja2 template file paths.
  • target-file or output (required): One of more target file paths. The number of files must match the number of template files.
  • base-dir: Base directory of the Jinja2 environment. Template file paths are relative to this directory. Default is the Buildout directory.
  • target-executable: One or more boolean flags (yes|no|true|false|1|0) indicating the executability of the target files. If only one flag is given it is applied to all target files.
  • eggs: Reserved for a list of eggs, conveniently converted into a pkg_resources.WorkingSet when specified
  • jinja2_filters: custom filter functions separated by white-space

Additional options are simply forwarded to the templates, and options from all the other parts are made available through parts.<part-name>.<option-name> and parts[<part-name>][<option-name>].

Lists of Values

It is possible for a recipe option to contain one or more values, separated by whitespace. A split filter is available for when you want to iterate over the whitespace separated values in your Jinja2 template:

#!/bin/sh
{% for cmd in cmds|split %}
   echo "{{ cmd }}"
{% endfor %}

Minimal Example

foo.txt is created from foo.txt.jinja2 without any extra options:

[buildout]
parts = foo

[foo]
recipe = brodul.recipe.template
template-file = foo.txt.jinja2
target-file = foo.txt

Larger Example

foo.txt is created from myapp/foo.txt.jinja2, bar.sh is created from myapp/bar.sh.jinja2, the second will be executable, and both templates can utilize the additional options specified:

[buildout]
parts = foo

[foo]
recipe = brodul.recipe.template
base-dir = myapp
template-file =
    foo.txt.jinja2
    bar.sh.jinja2
input =
    foo.txt
    bar.sh
output =
    false
    true
project_name = Another Example
author = Me

[bar]
dashed-value = borg
value = cash

foo.txt.jinja2:

{{ parts.bar['dashed-value'] }}
{{ parts.bar.value }}
{{ author }}

Note

{{ parts.bar.dashed-value }} won’t work, but you can access it as a dict key.

Dashed value in the same part

If there is a dashed-value in brodul.recipe.template part and you would like to reference it, use:

{{context['dashed-value']}}

Custom filters

The filter function is located in the same directory as the buildout.cfg in a filter.py file. If you want to use more filters separate them with a white space.

[buildout]
parts = foo

[foo]
recipe = brodul.recipe.template
input = foo.txt.jinja2
output = foo.txt
jinja2_filters = filter.bar

Changelog

Todo

Why this fork

  • there should be an input and output option in buildout (since the ‘-‘ in ‘target-file’ char is parsed by jinja2)
  • custom filters support
