An exception that a finally block passes on, or one that leaves a
built-in's callback, no longer becomes $.error again over an error thrown
after it; throwing a caught error again still makes it the last one.
$.sleep with more than 0 inside a getter, a conversion or a built-in's
callback now throws whether or not the platform has a clock, so the web
build throws there as the other builds do.
The compiler now keeps a function declaration's name with its code, so
$.stack no longer shows [anonymous] for a declared function that is
called after the function that declared it has returned. The member test
expects "Web" for $.os in the wasm build, as the engine gives there.
A getter, a conversion, a callback of a built-in function or a file
$.evalFile runs is executed on native frames, so the run cannot stop at a
$.sleep there. Such a call used to only mark the run to pause, so the
code after it ran first and the wait came later. $.sleep with more than 0
milliseconds now throws an Error there, as alert, confirm and prompt do.
toSource checked the 16,777,216-unit length limit only after a whole
string was written. A long string of characters that are escaped could
reach the heap limit first, which ends the run instead of throwing a
RangeError. The limit is now checked before each part is added.
A script's $ object now has the other members the Dollar object page
lists: about, appEncoding, bp, build, buildDate, colorPicker,
decimalPoint, engineName, error, flags, gc, getenv, setenv, global,
hiresTimer, level, line, locale, localize, memCache, os, screens, sleep,
stack, strict and version. Scripts also get the global
localize(object, ...values), toSource(value) and
Object.prototype.toSource().
Each run starts with the interface's locale and its own $ state;
$.setenv changes only the run's copy of LANG, LC_MESSAGES, LC_ALL and
OS, and $.getenv returns null for every other name. $.sleep waits from
0 to 1,000 ms between frames, and script.stop ends the wait. toSource
writes plain data only and throws on cycles, getters, host objects and
values past the data limits.
The script checker reports $.localize as a $ member instead of the
global localize function.
