IMPORTANT: Liquid 2.6 is going to be the last version of Liquid which maintains explicit Ruby 1.8 compatability.
The following releases will only be tested against Ruby 1.9 and Ruby 2.0 and are likely to break on Ruby 1.8.

## Introduction
@@ -50,57 +47,4 @@ For standard use you can just pass it the content of a file and call render with
@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.
### Undefined variables and filters
By default, the renderer doesn't raise or in any other way notify you if some variables or filters are missing, i.e. not passed to the `render` method.
You can improve this situation by passing `strict_variables: true` and/or `strict_filters: true` options to the `render` method.
When one of these options is set to true, all errors about undefined variables and undefined filters will be stored in `errors` array of a `Liquid::Template` instance.
Here are some examples:
```ruby
template = Liquid::Template.parse("{{x}} {{y}} {{z.a}} {{z.b}}")
template.render({ 'x' => 1, 'z' => { 'a' => 2 } }, { strict_variables: true })
#=> '1 2 ' # when a variable is undefined, it's rendered as nil
template.errors
#=> [#<Liquid::UndefinedVariable: Liquid error: undefined variable y>, #<Liquid::UndefinedVariable: Liquid error: undefined variable b>]
```
```ruby
template = Liquid::Template.parse("{{x | filter1 | upcase}}")
template.render({ 'x' => 'foo' }, { strict_filters: true })
#=> '' # when at least one filter in the filter chain is undefined, a whole expression is rendered as nil
template.errors
#=> [#<Liquid::UndefinedFilter: Liquid error: undefined filter filter1>]
```
If you want to raise on a first exception instead of pushing all of them in `errors`, you can use `render!` method:
```ruby
template = Liquid::Template.parse("{{x}} {{y}}")
template.render!({ 'x' => 1}, { strict_variables: true })
#=> Liquid::UndefinedVariable: Liquid error: undefined variable y
```

# Profiler enables support for profiling template rendering to help track down performance issues.
#
# To enable profiling, first require 'liquid/profiler'.
# Then, to profile a parse/render cycle, pass the <tt>profile: true</tt> option to <tt>Liquid::Template.parse</tt>.
# After <tt>Liquid::Template#render</tt> is called, the template object makes available an instance of this
# class via the <tt>Liquid::Template#profiler</tt> method.
#
# template = Liquid::Template.parse(template_content, profile: true)
# output = template.render
# profile = template.profiler
#
# This object contains all profiling information, containing information on what tags were rendered,
# where in the templates these tags live, and how long each tag took to render.
#
# This is a tree structure that is Enumerable all the way down, and keeps track of tags and rendering times
# inside of <tt>{% include %}</tt> tags.
#
# profile.each do |node|
# # Access to the node itself
# node.code
#
# # Which template and line number of this node.
# # If top level, this will be "<root>".
# node.partial
# node.line_number
#
# # Render time in seconds of this node
# node.render_time
#
# # If the template used {% include %}, this node will also have children.
# node.children.each do |child2|
# # ...
# end
# end
#
# Profiler also exposes the total time of the template's render in <tt>Liquid::Profiler#total_render_time</tt>.
#
# All render times are in seconds. There is a small performance hit when profiling is enabled.
