class Parser extends SSTemplateParser (View source)

Parser that scans through a template and extracts the parameters to the _t and <%t calls

Methods

__construct(string $string, bool $warnIfEmpty = true)

No description

construct($matchrule, $name, $arguments = null)

Override the function that constructs the result arrays to also prepare a 'php' item in the array

setClosedBlocks(array $closedBlocks)

Set the closed blocks that the template parser should use

setOpenBlocks(array $openBlocks)

Set the open blocks that the template parser should use

addClosedBlock(string $name, callable $callable)

Add a closed block callable to allow <% name %><% end_name %> syntax

Lookup_AddLookupStep($res, $sub, $method)

The basic generated PHP of LookupStep and LastLookupStep is the same, except that LookupStep calls 'obj' to get the next ViewableData in the sequence, and LastLookupStep calls different methods (XML_val, hasValue, obj) depending on the context the lookup is used in.

Argument_DollarMarkedLookup($res, $sub)

If we get a bare value, we don't know enough to determine exactly what php would be the translation, because we don't know if the position of use indicates a lookup or a string argument.

Instead, we record 'ArgumentMode' as a member of this matches results node, which can be:

  • lookup if this argument was unambiguously a lookup (marked as such)
  • string is this argument was unambiguously a string (marked as such, or impossible to parse as lookup)
  • default if this argument needs to be handled as per 2.4

In the case of 'default', there is no php member of the results node, but instead 'lookup_php', which should be used by the parent if the context indicates a lookup, and 'string_php' which should be used if the context indicates a string

ClosedBlock__construct($res)

As mentioned in the parser comment, block handling is kept fairly generic for extensibility. The match rule builds up two important elements in the match result array: 'ArgumentCount' - how many arguments were passed in the opening tag 'Arguments' an array of the Argument match rule result arrays

Once a block has successfully been matched against, it will then look for the actual handler, which should be on this class (either defined or extended on) as ClosedBlock_Handler_Name(&$res), where Name is the tag name, first letter captialized (i.e Control, Loop, With, etc).

This function will be called with the match rule result array as it's first argument. It should return the php result of this block as it's return value, or throw an error if incorrect arguments were passed.
