Thanks to a little chat (and a few beers) with Zak at the conference, I got wondering if this syntax would be a sensible addition...
The principle is to enable rapid prototyping of getter and setter methods.....
class something {
var getBanana setBanana $banana = 12;
var getOrange $orange =1;
function setOrange($value) {
if ($value == $this->banana) {
echo "mmh banana's and oranges are the same"; }
}
}
$t = new something;
echo $t->getBanana();
echo $t->setBanana(3);
echo $t->setOrange(3);
syntax:
var [getter method] [setter method] $variable .....;
or any other ideas
var (getBanana, setBanana) $banana
function var getBanana, setBanana for $banana = '12'; // nice bit of token recycling.....
var use getBanana and setBanana for $banana = '12';
from a quick play with zend_language_parser.y the additionall code to
class_variable_decleration:
would look a bit like this...
| is_reference T_STRING T_VARIABLE '=' static_scalar {
znode tmp;
znode tmpthis; znode tmpfinalval;
zend_copy_value(tmpthis, 'this', 5);
tmpthis->type = IS_STRING;
zend_do_declare_property(&$3, &$6 TSRMLS_CC);
function.u.opline_num = CG(zend_lineno);
zend_do_begin_function_declaration(&function, &$3, 1, $2.op_type TSRMLS_CC); }
# get the 'this' part..
zend_do_fetch_globals(&tmpthis TSRMLS_CC);
zend_do_begin_variable_parse(TSRMLS_C);
fetch_simple_variable(&tmp, &tmpthis, 1 TSRMLS_CC);
zend_do_fetch_property(&tmpfinalval, &tmp, &$6 TSRMLS_CC);}
zend_do_return(&tmpfinalval, 1 TSRMLS_CC);
zend_do_end_function_declaration(&$1 TSRMLS_CC);
}
Anyway before I get carried away and actually test this :) - anybody got any thoughts.....
