class Monad m => HasTemplates m hs where

Methods

defaultLayout :: ControllerT hs m (Maybe Template)

The layout to use by default. Layouts are just templates that embed views. They are rendered with the a global object containing the rendered view in the "yield" field, and the object the view was rendered with in the "page" field. By default, no template is used.

viewDirectory :: ControllerT hs m FilePath

The directory to look for views passed to render. This defaults to "views", so

 render "index.html.tmpl" ...

will look for a view template in "views/index.html.tmpl".

functionMap :: ControllerT hs m FunctionMap

A map of pure functions that can be called from within a template. See FunctionMap and Function for details.

getTemplate :: FilePath -> ControllerT hs m Template

Function to use to get a template. By default, it looks in the viewDirectory for the given file name and compiles the file into a template. This can be overriden to, for example, cache compiled templates in memory.

render :: ToJSON a => FilePath -> a -> ControllerT hs m ()

Renders a view template with the default layout and a global used to evaluate variables in the template.

renderPlain :: ToJSON a => FilePath -> a -> ControllerT hs m ()

Same as render but without a template.

renderLayout :: ToJSON a => FilePath -> FilePath -> a -> ControllerT hs m ()

Render a view using the layout named by the first argument.

renderLayout' :: ToJSON a => Template -> FilePath -> a -> ControllerT hs m ()

Same as renderLayout but uses an already compiled layout.

defaultGetTemplate :: (HasTemplates m hs, MonadIO m) => FilePath -> ControllerT hs m Template

defaultRender :: (HasTemplates m hs, Monad m, ToJSON a) => FilePath -> a -> ControllerT hs m ()

defaultFunctionMap :: FunctionMap

fromList :: (Eq k, Hashable k) => [(k, v)] -> HashMap k v

O(n*log n) Construct a map with the supplied mappings. If the list contains duplicate mappings, the later mappings take precedence.

newtype Function

A funcation that's callable from inside a template
