+# How to contribute
+
+## Things we will merge
+
+* Bugfixes
+* Performance improvements
+* Features which are likely to be useful to the majority of Liquid users
+
+## Things we won't merge
+
+* Code which introduces considerable performance degrations
+* Code which touches performance critical parts of Liquid and comes without benchmarks
+* Features which are not important for most people (we want to keep the core Liquid code small and tidy)
+* Features which can easily be implemented on top of Liquid (for example as a custom filter or custom filesystem)
+* Code which comes without tests
+* Code which breaks existing tests
+
+## Workflow
+
+* Fork the Liquid repository
+* Create a new branch in your fork
+* If it makes sense, add tests for your code and run a performance benchmark
+* Make sure all tests pass
+* Create a pull request
+* In the description, ping one of [@boourns](https://github.com/boourns), [@fw42](https://github.com/fw42), [@camilo](https://github.com/camilo), [@dylanahsmith](https://github.com/dylanahsmith), or [@arthurnn](https://github.com/arthurnn) and ask for a code review.

+## Before 1.9.0
+
+* Added If with or / and expressions
+* Implemented .to_liquid for all objects which can be passed to liquid like Strings Arrays Hashes Numerics and Booleans. To export new objects to liquid just implement .to_liquid on them and return objects which themselves have .to_liquid methods.
+* Added more tags to standard library
+* Added include tag ( like partials in rails )
+* [...] Gazillion of detail improvements
+* Added strainers as filter hosts for better security [Tobias Luetke]
+* Fixed that rails integration would call filter with the wrong "self" [Michael Geary]

+* Removed count helper from standard lib. use size [Tobias Luetke]
+* Fixed bug with string filter parameters failing to tolerate commas in strings. [Paul Hammond]
+* Improved filter parameters. Filter parameters are now context sensitive; Types are resolved according to the rules of the context. Multiple parameters are now separated by the Liquid::ArgumentSeparator: , by default [Paul Hammond]
+    {{ 'Typo' | link_to: 'http://typo.leetsoft.com', 'Typo - a modern weblog engine' }}
+* Added Liquid::Drop. A base class which you can use for exporting proxy objects to liquid which can acquire more data when used in liquid. [Tobias Luetke]
+
+  class ProductDrop < Liquid::Drop
+    def top_sales
+       Shop.current.products.find(:all, :order => 'sales', :limit => 10 )

+  end
+  t = Liquid::Template.parse( ' {% for product in product.top_sales %} {{ product.name }} {% endfor %} '  )
+  t.render('product' => ProductDrop.new )
+* Added filter parameters support. Example: {{ date | format_date: "%Y" }} [Paul Hammond]

+## Introduction
+
+Liquid is a template engine which was written with very specific requirements:
+
+* It has to have beautiful and simple markup. Template engines which don't produce good looking markup are no fun to use.
+* It needs to be non evaling and secure. Liquid templates are made so that users can edit them. You don't want to run code on your server which your users wrote.
+* It has to be stateless. Compile and render steps have to be separate so that the expensive parsing and compiling can be done once and later on you can just render it passing in a hash with local variables and objects.
+
+## Why you should use Liquid
+
+* You want to allow your users to edit the appearance of your application but don't want them to run **insecure code on your server**.
+* You want to render templates directly from the database.
+* You like smarty (PHP) style template engines.
+* You need a template engine which does HTML just as well as emails.
+* You don't like the markup of your current templating engine.
+
+## What does it look like?
+
+```html
+<ul id="products">
+  {% for product in products %}
+    <li>
+      <h2>{{ product.name }}</h2>
+      Only {{ product.price | price }}
+
+      {{ product.description | prettyprint | paragraph }}
+    </li>
+  {% endfor %}
+</ul>
+```
+

+Liquid supports a very simple API based around the Liquid::Template class.
+For standard use you can just pass it the content of a file and call render with a parameters hash.
+
+```ruby
+@template = Liquid::Template.parse("hi {{name}}") # Parses and compiles the template
+@template.render('name' => 'tobi')                # => "hi tobi"
+```
+
+### Error Modes
+
+Setting the error mode of Liquid lets you specify how strictly you want your templates to be interpreted.
+Normally the parser is very lax and will accept almost anything without error. Unfortunately this can make
+it very hard to debug and can lead to unexpected behaviour. 
+
+Liquid also comes with a stricter parser that can be used when editing templates to give better error messages
+when templates are invalid. You can enable this new parser like this:
+
+```ruby
+Liquid::Template.error_mode = :strict # Raises a SyntaxError when invalid syntax is used
+Liquid::Template.error_mode = :warn # Adds errors to template.errors but continues as normal
+Liquid::Template.error_mode = :lax # The default mode, accepts almost anything.
+```
+
+If you want to set the error mode only on specific templates you can pass `:error_mode` as an option to `parse`:
+```ruby
+Liquid::Template.parse(source, :error_mode => :strict)
+```
+This is useful for doing things like enabling strict mode only in the theme editor.
+
+It is recommended that you enable `:strict` or `:warn` mode on new apps to stop invalid templates from being created.
+It is also recommended that you use it in the template editors of existing apps to give editors better error messages.

-title: Introduction
-description: An overview of objects, tags, and filters in the Liquid template language.
----
-
-Liquid code can be categorized into [**objects**](#objects), [**tags**](#tags), and [**filters**](#filters).
-
-## Objects
-
-**Objects** tell Liquid where to show content on a page. Objects and variable names are denoted by double curly braces: `{% raw %}{{{% endraw %}` and `{% raw %}}}{% endraw %}`.
-
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-{{ page.title }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-Introduction
-```
-
-In this case, Liquid is rendering the content of an object called `page.title`, and that object contains the text `Introduction`.
-
-## Tags
-
-**Tags** create the logic and control flow for templates. They are denoted by curly braces and percent signs: `{% raw %}{%{% endraw %}` and `{% raw %}%}{% endraw %}`.
-
-The markup used in tags does not produce any visible text. This means that you can assign variables and create conditions and loops without showing any of the Liquid logic on the page.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-{% if user %}
-  Hello {{ user.name }}!
-{% endif %}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-Hello Adam!
-```
-
-Tags can be categorized into three types:
-
-- [Control flow]({{ "/tags/control-flow" | prepend: site.baseurl }})
-- [Iteration]({{ "/tags/iteration" | prepend: site.baseurl }})
-- [Variable assignments]({{ "/tags/variable" | prepend: site.baseurl }})
-
-You can read more about each type of tag in their respective sections.
-
-
-## Filters
-
-**Filters** change the output of a Liquid object. They are used within an output and are separated by a `|`.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-{{ "/my/fancy/url" | append: ".html" }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-{{ "/my/fancy/url" | append: ".html" }}
-```

-title: Operators
-description: Using operators to perform calculations in the Liquid template language.
----
-
-Liquid includes many logical and comparison operators.
-
-## Basic operators
-
-<table>
-  <tbody>
-    <tr>
-      <td><code>==</code></td>
-      <td>equals</td>
-    </tr>
-    <tr>
-      <td><code>!=</code></td>
-      <td>does not equal</td>
-    </tr>
-    <tr>
-      <td><code>&gt;</code></td>
-      <td>greater than</td>
-    </tr>
-    <tr>
-      <td><code>&lt;</code></td>
-      <td>less than</td>
-    </tr>
-    <tr>
-      <td><code>&gt;=</code></td>
-      <td>greater than or equal to</td>
-    </tr>
-    <tr>
-      <td><code>&lt;=</code></td>
-      <td>less than or equal to</td>
-    </tr>
-    <tr>
-      <td><code>or</code></td>
-      <td>logical or</td>
-    </tr>
-    <tr>
-      <td><code>and</code></td>
-      <td>logical and</td>
-    </tr>
-  </tbody>
-</table>
-
-For example:
-
-```liquid
-{% raw %}
-{% if product.title == "Awesome Shoes" %}
-  These shoes are awesome!
-{% endif %}
-{% endraw %}
-```
-
-You can use multiple operators in a tag:
-
-```liquid
-{% raw %}
-{% if product.type == "Shirt" or product.type == "Shoes" %}
-  This is a shirt or a pair of shoes.
-{% endif %}
-{% endraw %}
-```
-
-## contains
-
-`contains` checks for the presence of a substring inside a string.
-
-```liquid
-{% raw %}
-{% if product.title contains 'Pack' %}
-  This product's title contains the word Pack.
-{% endif %}
-{% endraw %}
-```
-
-`contains` can also check for the presence of a string in an array of strings.
-
-```liquid
-{% raw %}
-{% if product.tags contains 'Hello' %}
-  This product has been tagged with 'Hello'.
-{% endif %}
-{% endraw %}
-```
-
-`contains` can only search strings. You cannot use it to check for an object in an array of objects.

-title: Truthy and falsy
-description: An overview of boolean logic in the Liquid template language.
----
-
-In programming, anything that returns `true` in a conditional is called **truthy**. Anything that returns `false` in a conditional is called **falsy**. All object types can be described as either truthy or falsy.
-
-- [Truthy](#truthy)
-- [Falsy](#falsy)
-- [Summary](#summary)
-
-## Truthy
-
-All values in Liquid are truthy except `nil` and `false`.
-
-In the example below, the string "Tobi" is not a boolean, but it is truthy in a conditional:
-
-```liquid
-{% raw %}
-{% assign tobi = "Tobi" %}
-
-{% if tobi %}
-  This condition will always be true.
-{% endif %}
-{% endraw %}
-```
-
-[Strings]({{ "/basics/types/#string" | prepend: site.baseurl }}), even when empty, are truthy. The example below will result in empty HTML tags if `settings.fp_heading` is empty:
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-{% if settings.fp_heading %}
-  <h1>{{ settings.fp_heading }}</h1>
-{% endif %}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```html
-<h1></h1>
-```
-
-## Falsy
-
-The falsy values in Liquid are [`nil`]({{ "/basics/types/#nil" | prepend: site.baseurl }}) and [`false`]({{ "/basics/types/#boolean" | prepend: site.baseurl }}).
-
-## Summary
-
-The table below summarizes what is truthy or falsy in Liquid.
-
-|               | truthy        | falsy         |
-| ------------- |:-------------:|:-------------:|
-| true          | •             |               |

----
-title: Types
-description: An overview of data types in the Liquid template language.
----
-
-Liquid objects can have one of six types:
-
-- [String](#string)
-- [Number](#number)
-- [Boolean](#boolean)
-- [Nil](#nil)
-- [Array](#array)
-
-You can initialize Liquid variables with the [assign]({{ "/tags/variable/#assign" | prepend: site.baseurl }}) or [capture]({{ "/tags/variable/#capture" | prepend: site.baseurl }}) tags.
-
-## String
-
-Declare a string by wrapping a variable's value in single or double quotes:
-
-```liquid
-{% raw %}
-{% assign my_string = "Hello World!" %}
-{% endraw %}
-```
-
-## Number
-
-Numbers include floats and integers:
-
-```liquid
-{% raw %}
-{% assign my_int = 25 %}
-{% assign my_float = 39.756 %}
-{% endraw %}
-```
-
-## Boolean
-
-Booleans are either `true` or `false`. No quotations are necessary when declaring a boolean:
-
-```liquid
-{% raw %}
-{% assign foo = true %}
-{% assign bar = false %}
-{% endraw %}
-```
-
-## Nil
-
-Nil is a special empty value that is returned when Liquid code has no results. It is **not** a string with the characters "nil".
-
-Nil is [treated as false]({{ "/basics/truthy-and-falsy" | prepend: site.baseurl }}) in the conditions of `if` blocks and other Liquid tags that check the truthfulness of a statement.
-
-In the following example, if the user does not exist (that is, `user` returns `nil`), Liquid will not print the greeting:
-
-```liquid
-{% raw %}
-{% if user %}
-  Hello {{ user.name }}!
-{% endif %}
-{% endraw %}
-```
-
-Tags or outputs that return `nil` will not print anything to the page.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-The current user is {{ user.name }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-The current user is
-```
-
-## Array
-
-Arrays hold lists of variables of any type.
-
-### Accessing items in arrays
-
-To access all the items in an array, you can loop through each item in the array using an [iteration tag]({{ "/tags/iteration" | prepend: site.baseurl }}).
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
-{% for user in site.users %}
-  {{ user }}
-{% endfor %}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-{% raw %}
-Tobi Laura Tetsuro Adam
-{% endraw %}
-```
-
-### Accessing specific items in arrays
-
-You can use square bracket `[` `]` notation to access a specific item in an array. Array indexing starts at zero.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
-{{ site.users[0] }}
-{{ site.users[1] }}
-{{ site.users[3] }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-Tobi
-Laura
-Adam
-```
-
-### Initializing arrays
-
-You cannot initialize arrays using only Liquid.
-
-You can, however, use the [split]({{ "/filters/split" | prepend: site.baseurl }}) filter to break a string into an array of substrings.

-title: Variations of Liquid
-description: An overview of the different installations of Liquid and how Liquid can change depending on where you're using it.
----
-
-Liquid is a flexible, safe language, and is used in many different environments. Liquid was created for use in [Shopify](https://www.shopify.com) stores, and is also used extensively on [Jekyll](https://jekyllrb.com) websites. Over time, both Shopify and Jekyll have added their own objects, tags, and filters to Liquid. The most popular versions of Liquid that exist are **Liquid**, **Shopify Liquid**, and **Jekyll Liquid**.
-
-This site documents the latest version of **Liquid** including betas and release candidates — that is, Liquid as it exists outside of Shopify and Jekyll. If you download the Liquid repository or install it as a [gem](https://rubygems.org/gems/liquid), you will get access to whatever objects, tags, and filters are in the version of Liquid that you chose.
-
-## Shopify
-
-Shopify always uses the latest version of Liquid as a base, but Shopify adds a significant number of objects, tags, and filters to Liquid for use in merchants' stores. These include objects representing store, product, and customer information, and filters for displaying store data and manipulating storefront assets like product images.
-
-Shopify's version of Liquid is documented in the [Shopify Help Center](https://help.shopify.com/themes/liquid). If you want to try out Shopify's version of Liquid, you can [start a free trial of Shopify](https://www.shopify.com/signup) or use a sandbox like [DropPen](http://droppen.org/).
-
-## Jekyll
-
-[Jekyll](https://jekyllrb.com) is a static site generator, a command-line tool that creates websites by merging templates with content files. Jekyll uses Liquid as its template language, and adds a few objects, tags, and filters. These include objects representing content pages, tags for including snippets of content in others, and filters for manipulating strings and URLs.
-
-Jekyll also powers [GitHub Pages](https://pages.github.com/), a web hosting service that lets you push a Jekyll installation to a GitHub repository and have the resulting website published. This website is built using GitHub Pages.
-
-Jekyll might not be using the latest version of Liquid. This means that the tags and filters listed on this site may not work in Jekyll. Often the Jekyll project will wait for a stable release of Liquid rather than using a beta or release candidate version. To see what version of Liquid Jekyll is using, check the **runtime dependencies** section of [Jekyll's gem page](https://rubygems.org/gems/jekyll).
-
-Jekyll's version of Liquid is documented in the [Templates section of Jekyll's documentation](http://jekyllrb.com/docs/templates/). If you want to try out Jekyll's version of Liquid, you can clone the Jekyll project or install Jekyll as a gem and test Liquid on a static site.

----
-
-In Liquid, you can include a hyphen in your tag syntax `{% raw %}{{-{% endraw %}`, `{% raw %}-}}{% endraw %}`, `{% raw %}{%-{% endraw %}`, and `{% raw %}-%}{% endraw %}` to strip whitespace from the left or right side of a rendered tag.
-
-Normally, even if it doesn't output text, any line of Liquid in your template will still output a blank line in your rendered HTML:
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{% assign my_variable = "tomato" %}
-{{ my_variable }}
-```
-{% endraw %}
-
-Notice the blank line before "tomato" in the rendered template:
-
-<p class="code-label">Output</p>
-``` text
-{% assign my_variable = "tomato" %}
-{{ my_variable }}
-```
-
-By including hyphens in your `assign` tag, you can strip the generated whitespace from the rendered template:
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{%- assign my_variable = "tomato" -%}
-{{ my_variable }}
-```
-{% endraw %}
-
-<p class="code-label">Output</p>
-``` text
-tomato
-```
-
-If you don't want any of your tags to output whitespace, as a general rule you can add hyphens to both sides of all your tags (`{% raw %}{%-{% endraw %}` and `{% raw %}-%}{% endraw %}`):
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{% assign username = "John G. Chalmers-Smith" %}
-{% if username and username.size > 10 %}
-  Wow, {{ username }}, you have a long name!
-{% else %}
-  Hello there!
-{% endif %}
-```
-{% endraw %}
-
-<p class="code-label">Output without whitespace control</p>
-``` text
-{% assign username = "John G. Chalmers-Smith" %}
-{% if username and username.size > 10 %}
-  Wow, {{ username }}, you have a long name!
-{% else %}
-  Hello there!
-{% endif %}
-```
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{%- assign username = "John G. Chalmers-Smith" -%}
-{%- if username and username.size > 10 -%}
-  Wow, {{ username }}, you have a long name!
-{%- else -%}
-  Hello there!
-{%- endif -%}
-```
-{% endraw %}
-
-<p class="code-label">Output with whitespace control</p>
-``` text
-Wow, John G. Chalmers-Smith, you have a long name!

-<p class="code-label">Output</p>

-{{ 5 | divided_by: 3 }}
-```
-
-### Controlling rounding
-
-`divided_by` produces a result of the same type as the divisor — that is, if you divide by an integer, the result will be an integer. If you divide by a float (a number with a decimal in it), the result will be a float.
-
-For example, here the divisor is an integer:
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{{ 20 | divided_by: 7 }}
-```
-{% endraw %}
-
-<p class="code-label">Output</p>
-``` text
-{{ 20 | divided_by: 7 }}
-```
-
-Here it is a float:
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{{ 20 | divided_by: 7.0 }}
-```
-{% endraw %}
-
-<p class="code-label">Output</p>
-``` text
-{{ 20 | divided_by: 7.0 }}
-```
-
-### Changing variable types
-
-You might want to use a variable as a divisor, in which case you can't simply add `.0` to convert it to a float. In these cases, you can `assign` a version of your variable converted to a float using the `times` filter.
-
-In this example, we're dividing by a variable that contains an integer, so we get an integer:
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{% assign my_integer = 7 %}
-{{ 20 | divided_by: my_integer }}
-```
-{% endraw %}
-
-<p class="code-label">Output</p>
-``` text
-{% assign my_integer = 7 %}
-{{ 20 | divided_by: my_integer }}
-```
-
-Here, we [multiply]({{ site.baseurl}}/filters/times) the variable by `1.0` to get a float, then divide by the float instead:
-
-<p class="code-label">Input</p>
-{% raw %}
-``` liquid
-{% assign my_integer = 7 %}
-{% assign my_float = my_integer | times: 1.0 %}
-{{ 20 | divided_by: my_float }}
-```
-{% endraw %}
-
-<p class="code-label">Output</p>

-### Custom ellipsis
-
-`truncate` takes an optional second parameter that specifies the sequence of characters to be appended to the truncated string. By default this is an ellipsis (...), but you can specify a different sequence.
-
-The length of the second parameter counts against the number of characters specified by the first parameter. For example, if you want to truncate a string to exactly 10 characters, and use a 3-character ellipsis, use **13** for the first parameter of `truncate`, since the ellipsis counts as 3 characters.
