• default - returns the given variable unless it is null or the empty string, when it will return the given value, e.g. {{ undefined_variable | default: "Default value" }} #=> "Default value"
• divided_by - integer division e.g. {{ 10 | divided_by:3 }} #=> 3
• downcase - convert an input string to lowercase
• escape_once - returns an escaped version of html without affecting existing escaped entities
• escape - html escape a string
• first - get the first element of the passed in array
• floor - rounds a number down to the nearest integer, e.g. {{ 4.6 | floor }} #=> 4
• join - join elements of the array with certain character between them
• last - get the last element of the passed in array
• lstrip - strips all whitespace from the beginning of a string
• map - map/collect an array on a given property
• minus - subtraction e.g. {{ 4 | minus:2 }} #=> 2
• modulo - remainder, e.g. {{ 3 | modulo:2 }} #=> 1
• newline_to_br - replace each newline (\n) with html break
• pluralize - return the second word if the input is not 1 , otherwise return the first word e.g. {{ 3 | pluralize: 'item', 'items' }} #=> 'items'
• plus - addition e.g. {{ '1' | plus:'1' }} #=> 2 , {{ 1 | plus:1 }} #=> 2
• prepend - prepend a string e.g. {{ 'bar' | prepend:'foo' }} #=> 'foobar'
• remove_first - remove the first occurrence e.g. {{ 'barbar' | remove_first:'bar' }} #=> 'bar'
• remove - remove each occurrence e.g. {{ 'foobarfoobar' | remove:'foo' }} #=> 'barbar'
• replace_first - replace the first occurrence e.g. {{ 'barbar' | replace_first:'bar','foo' }} #=> 'foobar'
• replace - replace each occurrence e.g. {{ 'foofoo' | replace:'foo','bar' }} #=> 'barbar'
• reverse - reverses the passed in array
• round - rounds input to the nearest integer or specified number of decimals e.g. {{ 4.5612 | round: 2 }} #=> 4.56
• rstrip - strips all whitespace from the end of a string
• size - return the size of an array or string
• slice - slice a string. Takes an offset and length, e.g. {{ "hello" | slice: -3, 3 }} #=> llo
• sort - sort elements of the array
• split - split a string on a matching pattern e.g. {{ "ab" | split:"" }} #=> ['a','b']

• strip_newlines - strip all newlines (\n) from string
• strip - strips all whitespace from both ends of the string
• times - multiplication e.g {{ 5 | times:4 }} #=> 20

Hi @nulian ,

I've got a question about capitalise function.

In the case of an input "hello world!" should it the output be like
"Hello world!" or "Hello World!"?

[nulian]

The original liquid documentation isn't really clear about it and there tests either I'll give it a try in my ruby client. Which you can always do to double check the results using the ruby liquid version and testing it in it.

https://github.com/Shopify/liquid Shouldn't be too hard to load in a ruby console.

And capitalize should be "Hello world!" after trying it in liquid ruby version

But I see you already found it out in the merge request 👍

@art4ride are all these filters implemented now?

Updated the list with what is implemented
