- output values with controlable depth and detail
- add `.hidden` and `.depth` directives
- remove `eval_mode`
- add `use_strict` and `.strict` meta command
- add missing closures on global objects
- save and load command history to/from `~/.qjs_history`
- use USEPROFILE variable on Windows in addition to HOME
- use the same style names as util.inspect
* Add utility functions, improve integer conversion functions
- move `is_be()` to cutils.h
- add `is_upper_ascii()` and `to_upper_ascii()`
- add extensive benchmark for integer conversion variants in **tests/test_conv.c**
- add `u32toa()`, `i32toa()`, `u64toa()`, `i64toa()` based on register shift variant
- add `u32toa_radix()`, `u64toa_radix()`, `i64toa_radix()` based on length_loop variant
- use direct converters instead of `snprintf()`
- copy NaN and Infinity directly in `js_dtoa1()`
- optimize `js_number_toString()` for small integers
- use `JS_NewStringLen()` instead of `JS_NewString()` when possible
- add more precise conversion tests in microbench.js
- disable some benchmark tests for gcc (they cause ASAN failures)
- `-s` strips the source code
- `-ss` strips source and line/column numbers information
- `qjsc repl.js` generates an object size of **105726** bytes
- `qjsc -s repl.js` generates an object size of **20853** bytes
- `qjsc -ss repl.js` generates an object size of only **16147** bytes
- compile repl.js with `-ss`
- bump byte code version to 12
* Fix member accesses for non-decimal numeric literals
e.g. 0x0.a should return undefined, not SyntaxError.
* Remove ineffective non-decimal float parsing code and redundant checks on `is_float && radix != 10`
(The code already wasn't doing anything because of the `is_float` check.)
- improve `JS_DumpString`: use `L` prefix for wide strings
- dump variable kind and flags for locals and closures
- disassemble byte code in DUMP_READ_OBJECT
- pass start_pos to `dump_byte_code` and `dump_single_byte_code`
- write constant pool before function bytecode (bump version to 11)
- update generated code
* Expose public equality comparison and sameness public API.
- add `JS_IsEqual` (operator `==`), returns an `int`: `-1` if an exception was thrown
- add `JS_IsStrictEqual` (operator `===`) always succeeds, returns a `JS_BOOL`
- add `JS_IsSameValue` always succeeds, returns a `JS_BOOL`
- add `JS_IsSameValueZero` always succeeds, returns a `JS_BOOL`
- DUMP_XXX defined as nothing or 0 produces unconditional output
- DUMP_XXX defined as a bitmask produces conditional output based
on command line option -d<bitmask>
- add `JS_SetDumpFlags()` to select active dump options
- accept -d[<hex mask>] and --dump[=<hex mask>] to specify active
dump options, generalize command line option handling
- improve DUMP_READ_OBJECT output, fix indentation issue
In the pathological case shown in
https://github.com/quickjs-ng/quickjs/issues/367 both the object and the
registry will be destroyed as part of the GC phase of JS_FreeRuntime.
When the GC sweep happens it's possible we are holding on to a corpse so
avoid calling the registry callback in that case.
This is similar to how Weak{Map,Set} deal with iterators being freed as
part of a cycle.
Fixes: https://github.com/quickjs-ng/quickjs/issues/367
It was a wrapper around gcc's __builtin_expect macro but it was only
used in three places and not in a way that suggests it really helps
branch prediction on modern (or even not so modern) CPUs.

- avoid crashing on invalid atoms in `JS_AtomGetStrRT`
- do not dump objects and function_bytecode during
`JS_GC_PHASE_REMOVE_CYCLES` phase
- fix crash in `print_lines` on null source
* Improve REPL directive support
- use . on column 0 as directive prefix
- use `directives` object properties for genericity
- accept non ambiguous directive abbreviations
- reject invalid directive with extra characters
- simplify `handle_directive` and `handle_cmd`
- document ".help" instead of "\h"
- document ".load"
CMAKE_BUILD_TYPE only applies on single-configuration generators: https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html
For multi-configuration generators like Visual Studio (or Xcode) --config needs to be used in order to build that specific configuration.
* Improve completion in REPL
- refine `get_context_object` to avoid throwing errors (eg: q.<TAB>)
- do not call `eval` in `get_context_object` to avoid throwing errors
and reduce bloat caused by variable closures.
- support completion of directives
* Optimize `JS_GetPropertyInt64` and `JS_TryGetPropertyInt64`
- add `js_get_fast_array_element()` to special case arrays and typed arrays
- use `js_get_fast_array_element()` in `JS_GetPropertyValue()`,
`JS_TryGetPropertyInt64()` and `JS_GetPropertyInt64()`.
- simplify `js_array_at()`
- change error message for `Object.create` invalid property descriptor
- disable v8 test cases for deprecated legacy RegExp static properties
and invalid left hand side error type
- update v8.txt
- fix v8.sh behavior for single tests
Translate IC opcodes to their non-IC variants before writing them out.
Before this commit they were not byte-swapped properly, breaking the
ability to load serialized bytecode containing ICs on systems with
different endianness. Inline caches are recomputed as needed now.
A pleasing side effect of this change is that serialized bytecode is,
on average, a little smaller because fewer atoms are duplicated now.
