the compile-error reporting mechanism,
providing a way to associate exceptions
(very likely SyntaxError exceptions)
with compile-time errors.
(Hopefully this is temporary, as I'd
prefer one central place in the
error-reporting process to put the
js_ErrorToException call.)
Also changed the error reporter in js.c
to only ignore error reports marked with
the JSREPORT_EXCEPTION advisory flag when
the error occurs during javascript execution.
If it's at the toplevel compilation
level, then the error is still reported
(and the exception discarded.)
The api is feeling slightly dirtier, but
it still seems like the best
compromise...
enum JSErrNum, and changed a uintN
errorNumber declaration to JSErrNum.
It'd be nice to change the uintN
errorNumber field in JSErrorReport to
JSErrNum, but it's not clear that
JSErrNum is or should be exposed in the
API. Any C esthetes want to offer their
opinions?
It made my debugger slightly happier.
Including:
Preliminary work on internationalizing error messages
Preliminary work on exposing runtime errors as catchable exceptions
ECMA-proposed throw and try/catch/finally, with multiple catch clauses
and catchguards
ECMA-proposed in/instanceof operators
IEEE-conformant number to string conversion
Fixes and other good stuff.
the compiler to puhleeze let us used denormalized floating point
values, as required by the ECMA spec. Thanks to various contributors,
including Torsten R�ger <torsten@ponton-hamburg.de>, for working on
numeric issues. Fix courtesy wtc.
and development branches, including but
not limited to:
- Preliminary exception handling per
ECMA proposal; try, multiple
catchblocks, and finally. Catchblocks
are of the form catch (v) or
catch(v:<guard>), where guard is an
optional boolean expression that is
evaluated to determine whether the
exception is to be caught by that block.
- ECMA-proposed 'in' operator; "'foo' in
o" or "4 in o" asks if o has property
foo or element 4.
- Added a new set of defines in
jsconfig.h for js 1.4
features-in-progress. (in, instanceof,
exception handling.) Default build
version is now 1.4. Fixed a few
conditional features that had become
broken.
- Progress towards porting to FreeBSD
and Alpha; casts of NaN and friends to
int are a little more localized. Not
there yet...
- New config files to compile on more
OSes; various fixes to improve
portability.
