Rafal Kupiec	1f7e14fd7a	Finally, do it the proper way. This should fix all problems with accessing class attributes, at least I hope so.	2019-05-31 10:09:19 +02:00
Rafal Kupiec	519f5050b7	The easiest solutions are the best. Just look for attributes in object.	2019-05-31 06:54:01 +02:00

Rafal Kupiec	a3a2c8b619	Allow non-static methods inside static (final virtual) classes to be called statically.	2019-05-30 12:43:54 +02:00
Rafal Kupiec	ba1c840009	Allow a 'final virtual' classes to be declared. ... Virtual final classes are helpful in the case someone is wrapping common functions that are static, but the common class itself cannot be instantiated.	2019-05-30 09:44:46 +02:00

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	02471b4ccb	Do not install private methods from parent to subclass. ... All methods defined in superclass can be access by $this and $parent construct. There is no need to copy private methods, as they cannot be access in $this context.	2019-05-29 13:25:17 +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	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	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	7b6245572f	Remove constants management builtin functions.	2019-05-06 06:54:29 +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	03fc167be1	Proper implementation of so hated 'goto' statement.	2019-05-03 10:35:54 +02:00
Rafal Kupiec	2f3ce65289	Correct comment to if/else statements.	2019-05-02 19:03:47 +02:00
Rafal Kupiec	8f681d1605	Correct PH7_OP_JMPLFE debug name.	2019-05-01 20:24:37 +02:00
Rafal Kupiec	5a0e4667fa	More readable error message.	2019-05-01 20:09:55 +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	1d6822c1e2	Allow key and value declaration inside foreach() loop.	2019-05-01 11:38:28 +02:00
Rafal Kupiec	a726ab795a	Throw an error if $key or $value does not exist.	2019-05-01 09:51:33 +02:00
Rafal Kupiec	5c1e0f0cce	Simplify the foreach() loop implementation.	2019-04-30 23:59:02 +02:00
Rafal Kupiec	4d8d92092e	Refactor foreach() loop. ... In AerScript, the foreach() loop is syntatically more similiar to C#, than PHP. However the optional '$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
