Rafal Kupiec	4d1c246a65	Attempt to fix methods visibility mechanism.	2019-05-29 08:17:10 +02:00
Rafal Kupiec	1f5afc9d51	Reverse the logic. It does not seem to work actually.	2019-05-29 08:10:34 +02:00

Rafal Kupiec	4cc7940216	Correctly identify a member.	2019-05-17 09:05:17 +02:00
Rafal Kupiec	55acf8111f	Assume private visibility for all class members by default. ... In most (all?) modern OOP languages class members visibility is assumed to be private and programmer has to consciously set it to public or protected. PHP has the different approach what can cause a security flaws in written scripts. AerScript will not follow this way, as it seems to be conceptually broken.	2019-05-17 08:40:41 +02:00
Rafal Kupiec	48ccd7fef0	Copy all attributes from base classes and emit a warning if redeclared in subclass.	2019-05-17 06:52:29 +02:00

Rafal Kupiec	7203492763	Store a class name in each attribute.	2019-05-16 13:25:06 +02:00
Rafal Kupiec	f2116a6461	Always use HTTPS when possible.	2019-05-15 20:02:39 +02:00
Rafal Kupiec	5d9b73ba4e	Use method full name.	2019-05-15 19:45:39 +02:00
Rafal Kupiec	5256dda922	Attempt to fix '$this' and '$parent' constructs.	2019-05-10 23:45:32 +02:00
Rafal Kupiec	ea5499f8b3	Private methods should not be accessible from child class.	2019-05-09 13:53:22 +02:00
Rafal Kupiec	5e7d5957e2	Distinguish methods from attributes.	2019-05-09 13:43:01 +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	a2fb0b9ae5	Get rid of 'parent' constant. Use variable instead.	2019-05-08 08:38:40 +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	d3ae1c1bf4	Only identifiers should be allowed as constant name.	2019-05-06 18:38:56 +02:00

Rafal Kupiec	c4b63a3018	Rename OP_LOAD instruction to OP_LOADV.	2019-05-05 09:33:06 +02:00
Rafal Kupiec	23900f2aed	Remove unused compiler function - PH7_CompileLangConstruct(). ... In AerScript, there are no such language constructs, that have syntax similiar to functions. If so, it is just a builtin function.	2019-05-04 18:53:11 +02:00
Rafal Kupiec	b36510943d	Implement 'define' statement for defining constants globally.	2019-05-04 17:08:09 +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	e6b7f1be2c	Always emit OP_JMPLFE as goto can be used inside a loop and frame has to be left.	2019-05-03 10:55:57 +02:00

Rafal Kupiec	508e8965a9	VmExtractMemObj() should not be able to create a variable.	2019-05-01 18:29:57 +02:00
Rafal Kupiec	7d606cbf1d	Do not create variables automatically on each OP_CALL using VmExtractMemObj().	2019-05-01 18:19:04 +02:00
Rafal Kupiec	3dfa4232ba	Use VmCreateMemObj() to create $this.	2019-05-01 14:00:35 +02:00

Rafal Kupiec	5c1e0f0cce	Simplify the foreach() loop implementation.	2019-04-30 23:59:02 +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	f09d4def2d	It's AerScript.	2019-04-28 19:47:09 +02:00
Rafal Kupiec	d6fca929ea	Callbacks can be just called.	2019-04-28 19:36:27 +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	48a38dc1af	PH7_GenCompileError() always breaks script execution on E_ERROR. ... Thus code placed below will never get executed and is completely useless.	2019-04-24 23:12:59 +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	9b1ad67580	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 18:09:41 +02:00

Rafal Kupiec	c9203b6c91	New source code legal format.	2019-04-20 19:29:15 +02:00
Rafal Kupiec	ed8f3f341e	Remove array_same() builtin function. ... After last change, AerScript does not pass arrays as reference, so there is no chance to get this function return true, unless you pass array as reference.	2019-04-20 13:59:10 +02:00
Rafal Kupiec	18e77b9754	array_copy() is no longer needed. ... AerScript makes a copy of all arrays, except a situation when array is passed by reference. Thanks to that this ugly hack called an extension, introduced by Symisc can be removed.	2019-04-20 07:30:07 +02:00
Rafal Kupiec	d819820798	Always make an array copy. Fixes #48.	2019-04-20 07:19:35 +02:00
Rafal Kupiec	e794ffd97b	Fix PH7_HashmapDup(). ... This function needs to store the next index. Otherwise it will start to count from beginning, duplicating existing keys.	2019-04-19 20:16:42 +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	bd22425b46	Do not allow 'continue' statement in a switch case. ... Important rule while using continue statement is that, We can use continue statement only within the loops. Switch case is conditional block not a loop so we cannot execute the continue statement inside switch.	2019-04-17 11:13:29 +02:00
