Rafal Kupiec	6c277c1eca	Allow implicitly-typed variable declarations inside 'for' and 'foreach' loops.	2019-06-08 13:35:16 +02:00
Rafal Kupiec	0327c3130f	Do not allow to initialize an implicitly-typed variable with an array initializer.	2019-06-08 13:09:35 +02:00
Rafal Kupiec	78c416c6b8	Implement the implicit 'auto' type. ... An implicitly typed local variable is strongly typed just as if it had been declared the type, but the compiler determines the type. The following two declarations of $i are functionally equivalent: int $i = 10; // Explicitly typed. auto $i = 10; // Implicitly typed.	2019-06-08 12:55:57 +02:00
Rafal Kupiec	a00d30afa2	Set NULL data type instead of throwing an error.	2019-06-08 09:14:16 +02:00
Rafal Kupiec	65aaf7be67	Correct error message.	2019-06-07 19:32:28 +02:00

Rafal Kupiec	984429bc55	Disallow static method declarations in interface.	2019-05-30 20:34:24 +02:00
Rafal Kupiec	53199cac4e	Another fixes to OOP-related error reporting.	2019-05-30 20:18:20 +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	3cca5faa76	Store variable type in dedicated field.	2019-05-21 14:49:36 +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	e8c675bd8e	Store a pointer to class container to reduce memory usage.	2019-05-16 15:41:37 +02:00
Rafal Kupiec	7203492763	Store a class name in each attribute.	2019-05-16 13:25:06 +02:00
Rafal Kupiec	a2fb0b9ae5	Get rid of 'parent' constant. Use variable instead.	2019-05-08 08:38:40 +02:00
Rafal Kupiec	d3ae1c1bf4	Only identifiers should be allowed as constant name.	2019-05-06 18:38:56 +02:00
Rafal Kupiec	0a6b5a6f42	The 'self' and 'parent' keywords should be resolved at compile time.	2019-05-06 11:38:32 +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	7c37451520	Namespaces are not supported and broken, but compile them properly.	2019-05-01 13:49:07 +02:00
Rafal Kupiec	1829eff323	Fix interface and class compilation.	2019-05-01 13:37:14 +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	d72774f0f4	Namespaces in AerScript do not support aliases.	2019-04-25 23:31:48 +02:00
Rafal Kupiec	407fb09e8f	Throw an error only if this is not the end of tokens stream.	2019-04-25 19:24:53 +02:00

Rafal Kupiec	1c5982e764	There is no reason to use a loop here.	2019-04-24 23:45:46 +02:00
Rafal Kupiec	3be46532dd	Remove unused PH7_ErrorRecover() function.	2019-04-24 23:38:45 +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	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	555234e381	Get rid of variable variables. AerScript does not support it.	2019-04-22 12:01:11 +02:00
Rafal Kupiec	8f18ebf884	Update legal info.	2019-04-20 19:53:16 +02:00
