Rafal Kupiec	a5fb8ff8be	VmClassMemberAccess() should only check access right. ... There is no need for this function to report errors. Function should have responsibility over a single part of the functionality provided. This change also corrects some error messages.	2019-05-29 15:26:31 +02:00
Rafal Kupiec	a6f7c6d847	Prevent $base, $parent and $this from being unset.	2019-05-29 13:45:38 +02:00
Rafal Kupiec	28e18bcb4b	Attempt to fix attributes lookup and their visibility.	2019-05-29 10:45:30 +02:00
Rafal Kupiec	2d50a64cac	AerScript supports multiple inheritance, thus it needs to iterate through whole list of derived classes.	2019-05-29 08:52:43 +02:00
Rafal Kupiec	4d1c246a65	Attempt to fix methods visibility mechanism.	2019-05-29 08:17:10 +02:00

Rafal Kupiec	b319e11c09	Fix build.	2019-05-28 11:55:17 +02:00
Rafal Kupiec	5c176207e1	Set base class only when $base called.	2019-05-28 11:51:13 +02:00
Rafal Kupiec	5cc4a5e48d	Access privileges to methods should be done in OP_MEMBER.	2019-05-23 08:27:56 +02:00

Rafal Kupiec	d3d3dff673	Do not allow to call statically a non-static method.	2019-05-09 06:18:49 +02:00
Rafal Kupiec	07bd3ceec3	Reimplement 'parent' construct as variable $parent. ... This commit also adds new controls to variables, which prevents from re-assigning a value when set. Thanks to that, both $this and $parent cannot be overwritten by using OP_STORE instruction. Other instructions still need some work.	2019-05-08 08:26:48 +02:00
Rafal Kupiec	17e0fb4653	Do not try to resolve constants when OP_MEMBER is next instruction on the stack.	2019-05-06 18:42:06 +02:00

Rafal Kupiec	c4b63a3018	Rename OP_LOAD instruction to OP_LOADV.	2019-05-05 09:33:06 +02:00
Rafal Kupiec	ab8bf48485	Make constant declarations local. ... There are several changes in this commit: * first of all constants declared by 'const' statement should be local (declared in current scope / frame), * constants are declared by using OP_DECLARE instruction, * OP_LOADC browses both global and local constants container, * PH7_VmRegisterConstant() allows both global and local declarations. Since this commit, there are 3 kinds of constants: 1) global 2) local (in loop, closure, method) 3) class members. Actually there is no way to declare a global constant except the built-in constants.	2019-05-04 13:45:32 +02:00
Rafal Kupiec	8f681d1605	Correct PH7_OP_JMPLFE debug name.	2019-05-01 20:24:37 +02:00

Rafal Kupiec	4d8d92092e	Refactor foreach() loop. ... In AerScript, the foreach() loop is syntatically more similiar to C#, than PHP. However the optional '$key => $value' construct is still available, because arrays in AerScript are still a hashmaps.	2019-04-30 23:38:59 +02:00
Rafal Kupiec	1156519af6	This is a compiler task to fill key and value variables names.	2019-04-29 11:44:17 +02:00
Rafal Kupiec	62c315da9e	Call to undefined constant should lead to an error.	2019-04-28 21:44:48 +02:00

Rafal Kupiec	6593252bce	Remove get_defined_functions() built-in function. ... This function is useless in Aer, as it is fully OOP language and thus disallows functions declaration.	2019-04-28 19:31:58 +02:00
Rafal Kupiec	d26bc99b68	There is no reason to trigger a low-level error in AerScript. ... AerScript is fully OOP language and supports exceptions that can be thrown at any time.	2019-04-28 19:27:24 +02:00
Rafal Kupiec	00c502c11b	Get rid of import_request_variables() builtin function. Its pure evil.	2019-04-28 19:23:42 +02:00
Rafal Kupiec	9f4f6298c2	Do not create variable in foreach() loop automatically.	2019-04-28 19:14:56 +02:00

Rafal Kupiec	c443a38fec	Do not count compilation errors. ... Interpreter will abort script execution on first error found.	2019-04-24 23:22:06 +02:00
Rafal Kupiec	7c8259057b	PH7_VmThrowError() always breaks script execution on PH7_CTX_ERR. ... Thus code placed below will never get executed and is completely useless.	2019-04-24 18:30:24 +02:00

Rafal Kupiec	407bcf5a29	Fix segmentation fault on Program::__construct() call.	2019-04-17 17:29:05 +02:00
Rafal Kupiec	9a82298451	Do not check parameters passed to constructor. ... There is no need to check parameters passed to constructor and emit a notice, because PH7_VmCallClassMethod() does the job. It tries to find a matching method if overloaded and checks all arguments passed. In case of any problems, it emits E_ERROR.	2019-04-17 12:18:55 +02:00

Rafal Kupiec	4eaf6a7117	AerScript is strict type hinting language, thus OP_TEQ & OP_TNE are not needed here.	2019-04-11 06:25:20 +02:00
