Content control

  <preserve>
  <compress>
  <silent>
  <pack>

The content control tags affects how character datas and non-template tags are processed and outputted. Behaviour is in effect until the end of function, or up to the next content control tag. Note that these tags does nothing on runtime; all actions are performed during compilation.

preserve

Content is treated as it is expressed in templates.

compress

Whitespace sequences are compressed into single whitespace:

• to line feed if there was line feeds on compressed sequence
• to space if there wasn't.

pack

Whitespace sequences are compressed into single space. Extra whitespace from beginning and end are removed altogether.

compress

Character data and non-template tags are not outputted.

Content control behaviour is also affected by preserve, compress and silent attributes in module, namespace, class and function definitions.
