Text.EDE.Filters

Description

The means to construct your own filters.

Synopsis

Prelude

The default filters available to a template are documented by the subsequent categories.

These filters cannot be overriden and attempting to supply your own filters to renderWith will cause the similarly named filters to disappear when they are merged with the prelude during evaluation. (See: union)

Boolean

! :: Bool -> Bool
See: not
&& :: Bool -> Bool -> Bool
|| :: Bool -> Bool -> Bool

Equality

== :: a -> a -> Bool
!= :: a -> a -> Bool
See: /=

Relational

> :: a -> a -> Bool
>= :: a -> a -> Bool
<= :: a -> a -> Bool
< :: a -> a -> Bool

Numeric

+ :: Scientific -> Scientific -> Scientific
- :: Scientific -> Scientific -> Scientific
* :: Scientific -> Scientific -> Scientific
abs :: Scientific -> Scientific
negate :: Scientific -> Scientific
signum :: Scientific -> Scientific

Fractional

ceiling :: Scientific -> Scientific
floor :: Scientific -> Scientific
round :: Scientific -> Scientific
truncate :: Scientific -> Scientific

Textual

dropLower :: Text -> Text
Drop preceding lowercase characters.
dropUpper :: Text -> Text
Drop preceding uppercase characters.
indentLines :: Text -> Text
prependLines :: Text -> Text
justifyLeft :: Text -> Text
Using whitespace as fill character.
justifyRight :: Text -> Text
Using whitespace as fill character.
center :: Text -> Text
Using whitespace as fill character.
replace :: Text -> Text
remove :: Text -> Text
Shortcut for: replace(pattern, "")
splitWords :: Text -> Text
strip :: Text -> Text
stripPrefix :: Text -> Text
stripSuffix :: Text -> Text
stripStart :: Text -> Text
stripEnd :: Text -> Text
takeWord :: Text -> Text
dropWord :: Text -> Text
lowerHead :: Text -> Text
upperHead :: Text -> Text
toCamel :: Text -> Text
toEllipsis :: Text -> Text
toEllipsisWith :: Text -> Text
toPascal :: Text -> Text
toSnake :: Text -> Text
toSpinal :: Text -> Text
toTitle :: Text -> Text
toTrain :: Text -> Text
toLower :: Text -> Text
toUpper :: Text -> Text
toOrdinal :: Scientific -> Text

Collection

length :: Collection -> Scientific
See: Text.length, Vector.length, HashMap.size
empty :: Collection -> Bool
See: Text.null, Vector.null, HashMap.null
reverse :: Collection -> Scientific
See: Text.reverse, Vector.reverse
head :: Collection -> Scientific
See: Text.head, Vector.head
last :: Collection -> Scientific
See: Text.last, Vector.last
tail :: Collection -> Scientific
See: Text.tail, Vector.tail
init :: Collection -> Scientific
See: Text.init, Vector.init
keys :: Collection -> Scientific
elems :: Collection -> Scientific

Polymorphic

show :: a -> Text
