Tor Andersson a65416046c Make instanceof a public function. 2014-01-23 09:13:39 +01:00
Tor Andersson c55b4e18bc Implement instanceof expression. 2014-01-23 00:16:21 +01:00
Tor Andersson 60253cedab Add stack and scope balancing to exits from try/catch blocks. 
Because finally blocks are inlined, their break and continue instructions
are duplicated so we need to use a list of jumps to patch instead of
a single instruction and target pointer.

Also save the top return value from the stack, since an interrupted
return (return out of a try block that has a finally with another
jump or return) will leave multiple return values on the stack.

Tor Andersson cf9867c833 Implement try/catch/finally exception handling. 
TODO: return/break/continue and finally.

 2014-01-22 03:14:37 +01:00
Tor Andersson 7389d25b1a Fix typos. 2014-01-21 16:36:15 +01:00
Tor Andersson 8b6493eece Implement with statement. 2014-01-21 15:49:36 +01:00
Tor Andersson 6c8400d872 Fix CFunction calling conventions. 
'this' is always argument 0 (even for constructors, where it is null).
argc is the number of real arguments (not counting the 'this' object).

for (i = 1; i <= argc; ++i)
	js_toXXX(J, i);

Tor Andersson 7c82ec2541 Clean up error object creation and throwing functions. 2014-01-20 18:27:52 +01:00
Tor Andersson b262cc3673 Rename many jsR functions to jsV. 
Danger! jsV work on values internally without the stack.

Also rearrange how C-constructors are created.
 2014-01-20 17:44:56 +01:00

Tor Andersson 702fb1eb4a Rename functions that push new objects on the stack. 2014-01-18 01:15:10 +01:00
Tor Andersson ffc82eabd7 Add allocation counter to trigger garbage collector during interpretation. 
Only trigger between function calls, during bytecode interpretation,
to allow for intra-function race conditions where an object has been
created but not yet inserted into the stack or environment scope chain.
 2014-01-18 00:57:18 +01:00
Tor Andersson 96ca91ec7c Garbage collector lists. 2014-01-17 23:02:14 +01:00
Tor Andersson 299dbda156 Move stack into state. 2014-01-17 22:42:15 +01:00
Tor Andersson 81b2bb9ca4 Add constructors called with 'new' keyword. 
Support built-in constructors that create their own objects. They get
called without a this object, which they should create and push on the
stack.
 2014-01-17 22:03:35 +01:00
Tor Andersson e431170dae Improve stackidx function to return "undefined" for out-of-bounds accesses. 2014-01-17 21:10:54 +01:00
Tor Andersson 060dbbb03c Create function objects with initial properties. 
Set "length" and "prototype" and "prototype.constructor" properties.

Only for functions, not script functions or C-functions.
 2014-01-17 21:03:22 +01:00
Tor Andersson f487a7db10 Set prototype internal property when creating objects. 2014-01-17 19:41:41 +01:00
Tor Andersson 5ce44f9d4a Remember file name and line where a function object came from. 
Make "debugger" statement useful: dump current function bytecode,
stack, and environment scope chain.
 2014-01-17 16:00:51 +01:00
Tor Andersson 10ffd559de Compile global/eval code as script objects rather than regular functions. 
Handle scoping rules ath the js_call level instead of having to use
separate functions to call on the objects.
 2014-01-17 15:58:51 +01:00
Tor Andersson f6c5c56b44 Keep the current environment scope chain in the js_State struct. 
Create script (global/eval code) functions without a scope (they're
not closures) and run them with js_eval so they can execute with the
current scope chain.

Normal functions still have a scope and are run with js_call.
 2014-01-17 14:58:03 +01:00

Tor Andersson 4a3fdcef74 Functions! 2014-01-16 00:23:27 +01:00
Tor Andersson ede0f888ce Prepare for objects with internal properties, and closures as objects. 2014-01-15 23:41:41 +01:00
Tor Andersson 6ba9e94d02 js_pushlstring() for pushing literal (and interned strings). 
js_pushstring() will intern its argument first.
 2014-01-15 17:03:12 +01:00
Tor Andersson 47e88ac805 Calculate stack index for both positive and negative numbers. 
Call all functions with "this" as the first argument.

Negative indexes count from the top, positive indexes count from
the current function call frame (so arguments start at 0).
 2014-01-15 01:34:30 +01:00
Tor Andersson 6b1906f3b5 Add for-in iterator. 2014-01-15 00:36:22 +01:00

 2014-01-14 18:17:06 +01:00
Tor Andersson a4cc139e1c Add js_Object with js_Property binary search tree. 
Use object to represent a variable record and implement variable
loading and storing in the interpreter.
 2014-01-13 21:32:33 +01:00
Tor Andersson 5756da56d1 Begin generating byte code. 2014-01-12 13:39:42 +01:00
