abbreviate

The abbreviate filter will abbreviate a string using an ellipsis. It takes one argument which is the max width of the desired output including the length of the ellipsis.

Example

{{{ "This is a sentence" | abbreviate(7) }}

Output

This...

abs

The abs filter is used to obtain the absolute value.

Example

{{ -5 | abs }}

Output

5

capitalize

The capitalize filter will capitalize the first letter of the string.

Example

{{ "this is a sentence" | capitalize }}

Output

This is a sentence

date

The date filter is used to format an existing java.util.Date object. The filter will construct a java.text.SimpleDateFormat using the provided pattern and then use this newly created SimpleDateFormat to format the provided Date object.
The alternative way to use this filter is to use it on a string but then provide two arguments. The first is the desired pattern for the output and the second is the existing format used to parse the input string into a java.util.Date object.

Example : If todayDate is a java.util.Date object

{{ todayDate | date("yyyy-MM-dd") }}

Output

2017-12-25


Example 2

{{ "December 25, 2017" | date("yyyy-MM-dd", existingFormat="MMMM dd, yyyy") }}

Output

2017-12-25

default

The default filter will render a default value if and only if the object being filtered is empty. A variable is empty if it is null, an empty string, an empty collection, or an empty map.

Example

{%- set str = "" -%}
{{ str | default("NonEmpty") }}

Output

NonEmpty

escape

The escape filter will turn special characters into safe character references in order to avoid XSS vulnerabilities.

Example

{{ "<content>" | escape }}

Output

<content>

first

The first filter will return the first item of a collection, or the first letter of a string.

Example

{{ "Some letters" | first }}

Output

S


Example 2

{{ [ "b", "a", "c" ] | first }}

Output

b

join

The join filter will concatenate all items of a collection into a string. An optional argument can be given to be used as the separator between items.

Example

{{ [ "This", "is", "a", "sentence" ] | join }}

Output

This is a sentence


Example 2

{{ [ "This", "is", "a", "sentence" ] | join(" ") }}

Output

This is a sentence

last

The last filter will return the last item of a collection, or the last letter of a string.

Example

{{ "Some letters" | last }}

Output

s


Example 2

{{ [ "b", "a", "c" ] | last }}

Output

c

length

The length filter returns the number of items of collection, map or the length of a string.

Example

{{ "Some letters" | length }}

Output

12


Example 2

{{ [ "b", "a", "c" ] | length }}

Output

3

lower

The lower filter makes an entire string lower case.

Example

{{ "THIS IS A SENTENCE" | lower }}

Output

this is a sentence

merge

The merge filter returns a new map, list or array that is the result of merging two maps, lists or arrays together.

Note

Keys in the second map will overwrite the first map keys.


Example

{%- set mapa = { "a": "aa", "b": "bb", "c": "cc" } -%}
{%- set mapb = { "c": "ccc", "d": "ddd", "e": "eee" } -%}
{{ mapa | merge(mapb) }}

Output

{a=aa, b=bb, c=ccc, d=ddd, e=eee}

numberformat

The numberformat filter is used to format a decimal number. Behind the scenes it uses java.text.DecimalFormat.

Example

{{ 3.14678 | numberformat("#.##") }}

Output

3.15

raw

The raw filter prevents the output of an expression from being escaped by the autoescaper. The raw filter must be the very last operation performed within the expression otherwise the autoescaper will deem the expression as potentially unsafe and escape it regardless.

Note

If the raw filter is not the last operation performed then the expression will be escaped.


Example

{{ "<content>" | raw }}

Output

<content>

replace

The replace filter returns a string that is the result of replacing any substrings matching keys in a map with the respective values.

Example

{{ "This is a sentence" | replace({ "i": "eye" }) }}

Output

Theyes eyes a sentence

rsort

The rsort filter will sort a list in reversed order. The items of the list must implement Comparable.

Example

{{ [ "b", "a", "c" ] | rsort }}

slice

Output

is a


Example 2

{{ [ "b", "a", "c" ] | slice(1, 2) }}

Output

[a[

sort

The sort filter will sort a list. The items of the list must implement Comparable.

Example

{{ [ "b", "a", "c" ] | sort }}

Output

[a, b, c[

title

The title filter will capitalize the first letter of each word.

Example

{{ "This is a sentence" | title }}

The urlencode filter translates a string into application/x-www-form-urlencoded format using the UTF-8 encoding scheme.

Example

{{ "list=[a,b,c]" | urlencode }}

Output

list%3D%5Ba%2Cb%2Cc%5D

lines

The lines filter will split a string by its line breaks with each line becoming an element in a list.

Example

Output

[Something, Is, On, Lots, Of, Lines]
