Smores allows you to specify a schema for user facing template features. It leverages marshmallow (hence 'smores') to populate and transform data that is then rendered via jinja. It has a parser that presents a more friendly syntax to users (ex. {user.addresses:1.street}). It also includes an autocomplete method that gives you intellisense style options given a tag fragment.
Smores provides two Marshmallow field types called TemplateString and TemplateFile. Templates defined in these fields are scoped to that schema and it's descendants. Each schema can have a _default_template that, if defined, will what is inserted if the associated tag ends with that schema. For example: typing {user.address} will render the _default_template for the Address schema. You can define other template attributes as well. For example, see the 'google_link' attribute of the Address schema below. Typing {user.address.google_link} will populate and insert that link.
smores.tag_autocomplete is a method where you can provide a tag 'fragment' and it will return the possible options below that. For example:
from smores import Smores, TemplateString
from marshmallow import Schema, fields
# instantiate a smores instance
smores = Smores()
# smores.schema registers the schema with the instance
@smores.schema
class Coordinates(Schema):
lat = fields.Decimal()
lng = fields.Decimal()
_default_template = TemplateString("{{lat}},{{lng}}")
@smores.schema
class Address(Schema):
street = fields.String()
suite = fields.String()
city = fields.String()
state = fields.String()
zipcode = fields.String()
coordinates = fields.Nested(Coordinates)
google_link = TemplateString('<a href="https://maps.google.com/?ll={{coordinates}}">View Map</a>')
_default_template = TemplateString("""
<div>{{<a href="https://maps.google.com/?ll={{coordinates}}">View Map</a>}}</div>
<div>{{street}} -- {{suite}}</div>
<div>{{city}}, {{state}} {{zipcode}}</div>
""")
@smores.schema
class User(Schema):
id = fields.Integer()
name = fields.String()
email = fields.Email()
address = fields.Nested(Address)
_default_template = TemplateString("""
<div>{{name}}</div>
<div>E: {{email}}</div>
<div>{{address}}</div>
""")
# for the schemas above, simply invoke the autocomplete method with a tag fragment
>>> smores.autocomplete("")
AutocompleteResponse(tagStatus='INVALID', options=['address', 'coordinates', 'user'])
>>> smores.autocomplete('user')
AutocompleteResponse(tagStatus='VALID', options=['_default_template', 'address', 'email', 'id', 'name'])
>>> smores.autocomplete('us')
AutocompleteResponse(tagStatus='INVALID', options=['user'])
>>> smores.autocomplete("user.address.coordinates")
AutocompleteResponse(tagStatus='VALID', options=['_default_template', 'lat', 'lng'])
# Receiving '_default_template' or no results means that the current tag fragment is valid but _default_template
# shouldn't be appended to the tag in the ui.
# provide data to the render function
