gobre.recipe.template 2.0

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 = gobre.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 = gobre.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 }}

Dashed value in the same part

If there is a dashed-value in gobre.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 = gobre.recipe.template
input = foo.txt.jinja2
output = foo.txt
jinja2_filters = filter.bar

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

• templates should not have the ability to change state of buildout

• Gather the changes of the other forks (buildout 2 support and Python 3 support + fixes into a new package).
