- 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).
Turned off 'super' keyword - was letting through some cut'n'pasted java
code quietly and blowing big chunks out of the codegen/interpreter later.
Anybody know why 'super' had an interesting value here? - there was no
support for it on any path that I could see.
- Merged the typelib types for array and array_with_length.
- Added typelib types for string_with_size and wstring_with_size
- Fixed array param conversion and cleanup - using two passes over the params where necessary.
- Added array conversions when calling wrapped JS objects.
- Added expanded array tests.
- Avoid repeated atomization of 'value' property name.
As this changed the generated interface signatures, I had to change all of the uses to avoid bustage. Any corners of the browser that aren't built by default, or that I haven't discovered how to build, may be at risk of bustage if they use string or wstring attributes. (This could mean blackwood; sorry, guys!)
Many thanks to Alec Flett (alecf@netscape.com) for preparing diffs for the mailnews portion of the signature changes; thanks also to Ariel Backenroth (arielb@rice.edu) and Mike Shaver (shaver@mozilla.org) for help with updating the tree with NS_DECL_NSIFOO macros; everwhere where one of these macros was used was one less place I had to manually add 'const'.
Also removed extraneous space from generated method signatures, leftover from Brendan's capitalization spam, and made 'const decl must be of type short or long' an error rather than just a warning.
