.pre.phpy pseudo language
The .pre.phpy
file is a normal grammer in kmyacc
(yacc
) style, with some transformations
applied to it:
- Nodes are created using the syntax
Name[subNode1: ..., subNode2: ...]
. This is transformed intonew PHPParser_Node_Name(array('subNode1' => ..., 'subNode2' => ...), #this->line)
(#
is used instead of$
because$
is a reservered character inkmyacc
grammars. It is later transformed back to$
) Name::abc
is transformed toPHPParser_Node_Name::abc
- Some function-like constructs are resolved (see
preprocessor.php
for a list)
