A CLI frontend for python-jinja2 based on: https://github.com/ssato/misc/blob/master/jinja2_template_render.py

• Author: Satoru SATOH <ssato@redhat.com>
• License: Same as python-jinja2, that is, BSD3.

It supports multiple configuration files in YAML or JSON or others to set parameters w/ -C|--contexts option, ex. -C a.yaml -C b.yaml -C c.json.

Composition of config files are handled by external python-anyconfig module if available.

• anyconfig on PyPI: http://pypi.python.org/pypi/anyconfig/
• python-anyconfig github site: https://github.com/ssato/python-anyconfig

It supports setting template search paths w/ -T|--template-paths. This is useful when using 'include' directive in templates; ex. -T .:templates/.

NOTE: The default search path will be [., templatedir] where templatedir is the directory in which the given template file exists if -T option is not given. And even if -T option is used, templatedir will be appended to that search paths at the end.

ssato@localhost% PYTHONPATH=. python tools/jinja2-cli -h
Usage: tools/jinja2-cli [OPTION ...] TEMPLATE_FILE

Options:
  -h, --help            show this help message and exit
  -T TEMPLATE_PATHS, --template-paths=TEMPLATE_PATHS
                        Colon ':' separated template search paths. Please note
                        that dir in which given template exists is always
                        included in the search paths (at the end of the path
                        list) regardless of this option. [., dir in which
                        given template file exists]
  -C CONTEXTS, --contexts=CONTEXTS
                        Specify file path and optionally its filetype, to
                        provides context data to instantiate templates.  The
                        option argument's format is
                        [type:]<file_name_or_path_or_glob_pattern> ex. -C
                        json:common.json -C ./specific.yaml -C yaml:test.dat,
                        -C yaml:/etc/foo.d/*.conf
  -o OUTPUT, --output=OUTPUT
                        Output filename [stdout]
  --dumpvars            Dump template variables instead of compile it
  -D, --debug           Debug mode
  -W, --werror          Exit on warnings if True such as -Werror optoin in gcc

please try make -C examples and see the results: "/tmp/jinja2-cli.examples.d/*.out".

If you're Fedora or Red Hat Enterprise Linux user, you can build and install [s]rpm by yourself:

$ python setup.py srpm && mock dist/python-jinja2-cli-<ver_dist>.src.rpm

or:

$ python setup.py rpm

Otherwise, try usual ways to build and/or install python modules such like 'pip install git+https://github.com/ssato/python-jinja2-cli' and 'python setup.py bdist', etc.

Try to run '[WITH_COVERAGE=1] ./pkg/runtest.sh [path_to_python_code]'.

The followings look having similar to this module, that is, these can processs YAML/JSON/... context files and render (compile) jinja2-based templates, I guess.

  • pallets/jinja#129 (https://github.com/mattrobenolt/jinja2/blob/cli/jinja2/cli.py)

    My implementation imported some ideas from this one.

• https://bitbucket.org/luisfernando/jinjaconfig

This module (python-jinja2-cli) might demonstrate a few advantages over them in the following respect:

• It can process multiple configuration file formats with python-anyconfig's help.
• It can process multiple cascading configuration files with python-anyconfig's help.
• It can process UTF-8 configuration (context) files and templates properly.
