pongo2-runner

A small utility to render pongo2 templates. Intended to be used as a smarter replacement to envsubst to create smarter configuration files in the context of containers.

Example

Given the following template file saved in ./examples/test-2.cfg

{% if env.SHELL == "/bin/zsh" %}
is_using_awesome_shell="true"
{% else %}
shell="{{ env.SHELL }}"
home="{{ env.HOME }}"
{% endif %}

The output of

SHELL=/bin/zsh pongo2-runner ./examples/test-2.cfg

is:

is_using_awesome_shell="true"

while the output of

SHELL=/bin/bash pongo2-runner ./examples/test-2.cfg

is:

shell="/bin/bash"
home="/home/username/"
