belliash	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
belliash	b36510943d	Implement 'define' statement for defining constants globally.	2019-05-04 17:08:09 +02:00
belliash	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

belliash	5c1e0f0cce	Simplify the foreach() loop implementation.	2019-04-30 23:59:02 +02:00
belliash	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
belliash	1156519af6	This is a compiler task to fill key and value variables names.	2019-04-29 11:44:17 +02:00

belliash	f09d4def2d	It's AerScript.	2019-04-28 19:47:09 +02:00
belliash	d6fca929ea	Callbacks can be just called.	2019-04-28 19:36:27 +02:00
belliash	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
belliash	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

belliash	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
belliash	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

belliash	c9203b6c91	New source code legal format.	2019-04-20 19:29:15 +02:00
belliash	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
belliash	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
belliash	d819820798	Always make an array copy. Fixes #48.	2019-04-20 07:19:35 +02:00
belliash	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

belliash	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
belliash	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
