Instance Attribute Details

#attr_wrapper ⇒ Object

The character that should wrap element attributes. This defaults to ' (an apostrophe). Characters of this type within the attributes will be escaped (e.g. by replacing them with ') if the character is an apostrophe or a quotation mark.

# File 'lib/hamlit/parser/haml_options.rb', line 62

def attr_wrapper
  @attr_wrapper
end

#autoclose ⇒ Object

A list of tag names that should be automatically self-closed if they have no content. This can also contain regular expressions that match tag names (or any object which responds to #===). Defaults to ['meta', 'img', 'link', 'br', 'hr', 'input', 'area', 'param', 'col', 'base'].

def autoclose
  @autoclose
end

#cdata ⇒ Object

Whether to include CDATA sections around javascript and css blocks when using the :javascript or :css filters.

This option also affects the :sass, :scss, :less and :coffeescript filters.

Defaults to false for html, true for xhtml. Cannot be changed when using xhtml.

end

#compiler_class ⇒ Object

The compiler class to use. Defaults to Haml::Compiler.

# File 'lib/hamlit/parser/haml_options.rb', line 174

def compiler_class
  @compiler_class
end

#encoding ⇒ Object

The encoding to use for the HTML output. This can be a string or an Encoding Object. Note that Haml does not automatically re-encode Ruby values; any strings coming from outside the application should be converted before being passed into the Haml template. Defaults to Encoding.default_internal; if that's not set, defaults to the encoding of the Haml template; if that's US-ASCII, defaults to "UTF-8".

# File 'lib/hamlit/parser/haml_options.rb', line 77

def encoding
  @encoding
end

#escape_attrs ⇒ Object

Sets whether or not to escape HTML-sensitive characters in attributes. If this is true, all HTML-sensitive characters in attributes are escaped. If it's set to false, no HTML-sensitive characters in attributes are escaped. If it's set to :once, existing HTML escape sequences are preserved, but other HTML-sensitive characters are escaped.

Defaults to true.

# File 'lib/hamlit/parser/haml_options.rb', line 86

def escape_attrs
  @escape_attrs
end

#escape_html ⇒ Object

Sets whether or not to escape HTML-sensitive characters in script. If this is true, = behaves like `&=`; otherwise, it behaves like `!=`. Note that if this is set, != should be used for yielding to subtemplates and rendering partials. See also Escaping HTML and Unescaping HTML.

Defaults to false.

# File 'lib/hamlit/parser/haml_options.rb', line 96

def escape_html
  @escape_html
end

#filename ⇒ Object

The name of the Haml file being parsed. This is only used as information when exceptions are raised. This is automatically assigned when working through ActionView, so it's really only useful for the user to assign when dealing with Haml programatically.



102
103
104
 
# File 'lib/hamlit/parser/haml_options.rb', line 102

def filename
  @filename
end

#format ⇒ Object

Determines the output format. The default is :html5. The other options are :html4 and :xhtml. If the output is set to XHTML, then Haml automatically generates self-closing tags and wraps the output of the Javascript and CSS-like filters inside CDATA. When the output is set to :html5 or :html4, XML prologs are ignored. In all cases, an appropriate doctype is generated from !!!.

If the mime_type of the template being rendered is text/xml then a format of :xhtml will be used even if the global output format is set to :html4 or :html5.

# File 'lib/hamlit/parser/haml_options.rb', line 123

  @format
end

#hyphenate_data_attrs ⇒ Object

If set to true, Haml will convert underscores to hyphens in all Custom Data Attributes As of Haml 4.0, this defaults to true.

109
 
# File 'lib/hamlit/parser/haml_options.rb', line 107

def hyphenate_data_attrs
  @hyphenate_data_attrs
end

#line ⇒ Object

The line offset of the Haml template being parsed. This is useful for inline templates, similar to the last argument to Kernel#eval.



111
112
113
 
# File 'lib/hamlit/parser/haml_options.rb', line 111

def line
  @line
end

#mime_type ⇒ Object

The mime type that the rendered document will be served with. If this is set to text/xml then the format will be overridden to :xhtml even if it has set to :html4 or :html5.

# File 'lib/hamlit/parser/haml_options.rb', line 128

# File 'lib/hamlit/parser/haml_options.rb', line 171

def parser_class
  @parser_class
end

#preserve ⇒ Object

A list of tag names that should automatically have their newlines preserved using the Haml::Helpers#preserve helper. This means that any content given on the same line as the tag will be preserved. For example, %textarea= "Foo\nBar" compiles to <textarea>Foo&#x000A;Bar</textarea>. Defaults to ['textarea', 'pre']. See also Whitespace Preservation.

# File 'lib/hamlit/parser/haml_options.rb', line 136

def preserve
  @preserve
end

#remove_whitespace ⇒ Object

If set to true, all tags are treated as if both whitespace removal options were present. Use with caution as this may cause whitespace-related formatting errors.

Defaults to false.



144
145
146
 
# File 'lib/hamlit/parser/haml_options.rb', line 144

def remove_whitespace
  @remove_whitespace
end

#suppress_eval ⇒ Object

Whether or not attribute hashes and Ruby scripts designated by = or ~ should be evaluated. If this is true, said scripts are rendered as empty strings.

Defaults to false.



151
152
153
 
# File 'lib/hamlit/parser/haml_options.rb', line 151

def suppress_eval
  @suppress_eval
end

#trace ⇒ Object

Enable template tracing. If true, it will add a 'data-trace' attribute to each tag generated by Haml. The value of the attribute will be the source template name and the line number from which the tag was generated, separated by a colon. On Rails applications, the path given will be a relative path as from the views directory. On non-Rails applications, the path will be the full path.

# File 'lib/hamlit/parser/haml_options.rb', line 182

def trace
  @trace
end

#ugly ⇒ Object

If set to true, Haml makes no attempt to properly indent or format the HTML output. This significantly improves rendering performance but makes viewing the source unpleasant.

Defaults to true in Rails production mode, and false everywhere else.
