jinplate

A command line Jinja2 renderer inspired by gomplate

jinplate can read from local and remote variable files in a number of formats and use them to render a local Jinja2 template file.

jinplate uses URIs to identify how to fetch and parse Jinja2 variable files.

Installation

pip install jinplate

To install with support for the tests and filters included with ansible, use

pip install jinplate[ansible]

Usage

jinplate --help
Usage: jinplate [OPTIONS] TEMPLATE_FILE DATASOURCES...

  A command line renderer for jinja templates

  TEMPLATE_FILE is the path to a jinja template file to render

  DATASOURCES is a list of URIs to data sources supported by jinplate which
  contain the template variables. Data sources are parsed and merged into a single
  dict in the order in which they are specified.

  --jinja-ext allows specifying a comma-separated list of import paths
  containing jinja extensions. Example: --jinja-ext jinja2.ext.i18n

Options:
  --jinja-ext TEXT
  --help            Show this message and exit.
