SilverStripe

class SSTemplateParser extends Parser implements TemplateParser

This is the parser for the SilverStripe template language. It gets called on a string and uses a php-peg parser to match that string against the language structure, building up the PHP code to execute that structure as it parses

The $result array that is built up as part of the parsing (see thirdparty/php-peg/README.md for more on how parsers build results) has one special member, 'php', which contains the php equivalent of that part of the template tree.

Some match rules generate alternate php, or other variations, so check the per-match documentation too.

Terms used:

Marked: A string or lookup in the template that has been explictly marked as such - lookups by prepending with "$" (like $Foo.Bar), strings by wrapping with single or double quotes ('Foo' or "Foo")

Bare: The opposite of marked. An argument that has to has it's type inferred by usage and 2.4 defaults.

Example of using a bare argument for a loop block: <% loop Foo %>

Block: One of two SS template structures. The special characters "<%" and "%>" are used to wrap the opening and (required or forbidden depending on which block exactly) closing block marks.

Open Block: An SS template block that doesn't wrap any content or have a closing end tag (in fact, a closing end tag is forbidden)

Closed Block: An SS template block that wraps content, and requires a counterpart <% end_blockname %> tag

Angle Bracket: angle brackets "<" and ">" are used to eat whitespace between template elements N: eats white space including newlines (using in legacy _t support)

Methods

__construct(array $closedBlocks = array(), array $openBlocks = array())

Set the closed blocks that the template parser should use

setOpenBlocks(array $openBlocks)

Set the open blocks that the template parser should use

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.

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

`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)`

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.
