- simplify column number tracking using a pointer to the beginning of line
instead of `eol` + `mark`.
- add `js_parse_error_pos` to report syntax errors with exact source position
for token parsing errors. This makes the syntax error reports much more precise.
eg: exact position of UTF-8 encoding error, invalid escape sequence, etc.
- add `JSSourcePos` type to use single opaque object for token source position
- add `emit_pos` to set the precise source position in code generation
- change `emit_op` to no longer emit source positions from `s->last_line_num` and `s->last_col_num`.
- remove `last_line_num` and `last_col_num` `JSParserState` members
- runtime errors on calls report the column number of calling function or method name.
- runtime errors on `new` expressions report the column number of the `neẁ` keyword.
- do not show source position in backtrace if debug information is missing
- fix spurious parsing bugs when `js_parse_skip_parens_token` could not reparse
the current token because of stack overflow detection.
- `js_parse_save_pos` now saves the current token and `js_parse_seek_back` always
restores the token, hence never fails, while `js_parse_seek_token` reparses the
saved token. This is needed to handle the weird semantics of `"\1"; "use strict";`
- simplify html comment detection
- update **tests/test_builtin,js** with more informative messages
- improve `assert()` and **tests/test_language.js** tests
- update **v8.txt** for updated column numbers in remaining errors
- 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
- `-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
- 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
* 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"
* 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
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.
* Improve `Date.parse()`
- rewrite `Date.parse()` with separate parsers
- return `NaN` for out of bounds field values as specified
- add `js_tzabbr` and `string_get_tzabbr` to handle timezone abbreviations
- improve `string_get_milliseconds` readability
- accept up to 9 decimals for millisecond fraction but truncate at 3
- accept many more alternative date/time formats
- add test cases in **tests/test_builtin.js**
- produce readable output for `Date` objects in repl
- use `JSON.stringify` to output `Date` and `string` values in **repl.js**
- remove `String.prototype.__quote`
- add `minimum_length` macro to specify argument array sizes (C99 except MSVC)
- v8.js: parse all environment variables and output them, update **v8.txt**
