Feature request: parse -D parameters with dot notation #82
Description
Request
Currently it seems like -D parameter names are treated as a single value. It would be useful if the parameter used dot notation to parse it and allow it to be accessed the same way that the yaml parameters are.
See below for an example.
Example
test.tmpl
{
foo: {{house.bathroom.size}}
bar: {{house.kitchen.size}}
}params.yaml
house:
bathroom:
size: 20CLI Command
$ jinja2 test.tmpl params.yaml -D house.kitchen.value=55Error Received
