A Loaded.t stores a parsed template in memory so it can be evaluated multiple times against different models more efficiently.

from_file env template_filename return result t.

env is environment parameters defined in Jg_types.environment. environment parameters consist of template_dirs, autoescape_flag etc.

from_chan env chan return result t.

same as from_file but read template from Stdlib.in_channel.

from_string env source_string return result t.

same as from_file but read template from source string.

eval context models t evaluates the loaded template in the given context with the given models(defined by closure). return result string.

models is getter function for some data-sources. For example, let models = fun key -> List.assoc key ("name", Tstr "taro"); ("age", Tint 20) let models2 = function "name" -> Tstr "taro" | "age" -> Tint 20 | _ -> Tnull
