kamidana is yet another jinja2's cli wrapper.
features
- using jinja2 file as template file (basic feature)
- various input formats support (json, yaml, toml, ...)
- the way of lookup template is changed, relative to parent template path
- gentle error message
- batch execution for speed-up (via kamidana-batch)
- rendering with individual filters (via --additionals option)
- (useful additionals modules (e.g. kamidana.additionals.naming ...)
