- Add JS1.5 getter/setter support in all its glory:
* getter function SN() {return ++x} at top-level or as a closure binds an SN
property getter than returns the incremented value of x. Likewise for
setter function SN(y) {return y = x}.
* getters and setters may be defined in an object literal:
o = {p getter:function() {return ++this.x},
p setter:function(y){return this.x = y},
x:42};
* getter= and setter= operators (compound tokens) may be used to bind getter
and setter properties dynamically:
o = new Object;
o.p getter= function() {return ++this.x};
o.p setter= function(y){return this.x = y};
o.x = 42;
Waldemar is concerned that this form will collide semantically with JS2, so
I am not committing to keeping it in JS1.5. I'd like to check my code in
ASAP so shaver can use it, and I'd also like to see this form get used (or
not) during Mozilla betas. Caveat emptor, and if you find this "dynamic"
or "imperative" form necessary and hard to substitute, please let me know.
If this proves important to users, then I think JS1.5 should keep it.
- Cleaned up property flags (in a binary-incompatible fashion -- who cares?) by
eliminating JSPROP_ASSIGNHACK and JSPROP_TINYIDHACK.
- Added JS_DONT_PRETTY_PRINT flag to be ORed with the indent argument to the
several JS_Decompile*() API calls. This avoids any newlines or identation in
the decompiled string.
- Improved and extended (for getter/setter non-reservation) scanner lookahead
by using a circular (power-of-2 sized) token buffer.
- Fix ECMA Edition 3 deviation where function f(){function g(){}} bound f.g by
mistake (it should arrange to make a closure named g in activations of f, but
it should not bind a property of function f).
+ merging of js/src and js/ref
+ elimination of most dependencies on NSPR
+ JS1.4 feature additions and accumulated bug fixes
More details are in last week's mozilla status report.
