Rafal Kupiec	c51b3dfa8a	Revert 89d5158d7e and a8a1a2cd51. Fix should be based on VM frames.	2019-04-13 14:39:57 +02:00
Rafal Kupiec	a8a1a2cd51	Fix variable declaration in loops.	2019-04-11 13:28:47 +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
Rafal Kupiec	d8f9db8f9a	Proper implementation of is_callback() & is_callable(). First one only performs a check if variable type is callback, while the second checks if function exists and if can be called.	2019-04-10 09:45:00 +02:00

Rafal Kupiec	4f29507c0d	The isset() function always results in true, thus it is useless. If passed as argument variable is not set, the interpreter will throw an error.	2019-03-23 19:51:19 +01:00

Rafal Kupiec	58103ea5fe	Mark method/closure call frame as active. ... It is impossible to dump the frame during its initialization, as it does not contain all necessary information. Such frame should be skipped. After initialization is done, the frame has to be marked as active just before evaluating a function body.	2018-09-16 19:52:24 +02:00

Rafal Kupiec	eb79ed500e	Store float values in an union. ... Single variable cannot have many values of different types. This also saves some memory, because union allocates memory just for one of its members.	2018-09-07 12:04:51 +02:00
Rafal Kupiec	af1d59dab4	Don't try to get an integer representation of float.	2018-09-07 06:49:50 +02:00

Rafal Kupiec	fd4206a227	Remove error_log() builtin function and corresponding PH7_VM_CONFIG_ERR_LOG_HANDLER. ... It was not fully implemented and such feature should be implemented in separate module or on developers own.	2018-09-03 19:03:05 +02:00
Rafal Kupiec	109f4e981a	Aer does not support custom error handlers. ... Errors are used only internally to emit notifications about compilation/execution problems. They should not be catched and handled by custom handlers, but properly configured (to be displayed or logged). Instead developers should use exceptions that can be catched with try-catch block.	2018-09-03 16:43:08 +02:00
Rafal Kupiec	5895141ae1	Add missing declarations.	2018-09-03 10:59:20 +02:00
Rafal Kupiec	a2acf64272	VmExtractDebugTrace() provides information about a kind of call. ... Both VmExtractDebugTrace() and VmDebugTrace structure should provide information whether it was object call or a static method call.	2018-09-02 20:15:17 +02:00
Rafal Kupiec	8bfaa83b04	Correct typo.	2018-09-01 20:19:10 +02:00

Rafal Kupiec	178f3820f6	Enable debugging. ... This commit introduces ne debug feature. The PH7 Engine limits the VM dump to the global scope. Since Aer Script is fully object-oriented language the dump option contains only information about last call of OP_DONE. This change, forces the VM to store all instructions set in a global container when debugging is enabled, thus providing information the dump of whole script parse.	2018-08-26 19:59:17 +02:00
Rafal Kupiec	ab5ee94f99	API function rename.	2018-08-26 19:18:33 +02:00

Rafal Kupiec	33523e4e8a	Block definitions for class and namespace.	2018-08-21 19:35:00 +02:00
Rafal Kupiec	4dbd3ea412	New memory subsystem. ... This is a new memory subsystem implementing heap calculations as well as new builtin functions: * get_memory_usage() * get_memory_peak_usage() * get_memory_limit() It also allows to set an upper memory limit, ensuring that processed script will not be able to allocate more memory from OS. New subsystem is based on work done in 'memory_limit' branch. Big thanks to devnexen! This finally fixes #25.	2018-08-18 19:24:38 +02:00
Rafal Kupiec	c83d6e13fc	Removing xExec. ... First of all, VFS is not a right place for this, finally it was not implemented anyway.	2018-08-16 21:37:34 +02:00

Rafal Kupiec	9100bf0696	Treat 'import' as a special keyword.	2018-08-16 16:32:28 +02:00
Rafal Kupiec	b5fe36c14b	There is no need for include_once() and require_once() ... Aer is object-oriented language and the code it includes is executed in the global scope. Global scope can contain only classes and namespaces and they cannot be re-declared. Thus every file can be included just once. We can leave this to programmer, or take care about it on interpreter side. With this commit, include() and require() builtin functions allows to load file just once. Thanks to that, there is no need for include_once() and require_once(). Done in scope of #30.	2018-08-16 16:12:29 +02:00
Rafal Kupiec	e208e778e0	Compile global scope independently, fixes #40.	2018-08-16 11:15:03 +02:00
