Get rid of 'parent' constant. Use variable instead.

Only identifiers should be allowed as constant name.

The 'self' and 'parent' keywords should be resolved at compile time.

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.

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

Always emit OP_JMPLFE as goto can be used inside a loop and frame has to be left.

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.

Do not count compilation errors.

Interpreter will abort script execution on first error found.
2019-04-24 23:22:06 +02:00

PH7_GenCompileError() always breaks script execution on E_ERROR.

Thus code placed below will never get executed and is completely useless.

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.

Always pop the l-value on variable declaration.

Otherwise, it might lead to unexpected behaviour including protected memory access and segmentation fault.
This finally fixes #49 .

The empty() function is useless in Aer.

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.
