Jinja Recursive Templating for the CLI. Recursively template one file or many folders of many files like a config management languages allow, without the whole config management language. Useful if you're switching from managing an application from config management to just docker and need some simple templating logic.
pip install jinjarecurse
$ jinjarecurse --help
jinjarecurse (CLI)
Usage:
jinjarecurse --vars=VARS_FILE --input=INPUT_PATH --output=OUTPUT_PATH
Options:
-v <file>, --vars <file>
-i <file>, --input <file>
-o <file>, --output <file>
Given a config file containing your variables e.g. vars.yaml:
#comment: not available
root: /
number: 1
dictionary:
street: 123 North Ave
city: New York
state: New York
list:
- ABC
- DEF
- HJK
layer_1:
layer_2:
layer_3: last
And an input file jinja2 template e.g. i_file:
# Top level
{{root}}
{{number}}
{{dictionary}}
{{list}}
{{layer_1}}
# Nested data
{{dictionary.street}}
{{dictionary.city}}
{{dictionary.state}}
{{layer_1.layer_2.layer_3}}
You can populate it and specify an output filepath e.g. o_file:
$ jinjarecurse -v example/vars.yaml -i example/i_file -o example/o_file
WARNING: example/o_file (output) exists and any conflicting files will be overwritten
Writing from example/i_file to example/o_file
Contents of the output file e.g. o_file:
# Top level
/
1
{'street': '123 North Ave', 'city': 'New York', 'state': 'New York'}
['ABC', 'DEF', 'HJK']
{'layer_2': {'layer_3': 'last'}}
# Nested data
123 North Ave
New York
New York
last
You can also template an entire directory e.g. i_dir at once. Note the
output files in the output directory will maintain the filenames from the
input directory:
$ jinjarecurse -v example/vars.yaml -i example/i_dir -o example/o_dir
Writing from example/i_dir/i_file to example/o_dir/i_file
Writing from example/i_dir/i_file_1 to example/o_dir/i_file_1
Writing from example/i_dir/i_file_2 to example/o_dir/i_file_2
To run the unit tests, first install the dependencies:
$ pipenv install --dev .
Then invoke pytest:
$ pipenv run py.test -vvvs
