### v0.5.1 [[code][c0.5.1], [diff][d0.5.1]]
|

|
|
|
||
|
|
[c0.5.1]: https://github.com/aseemk/json5/tree/v0.5.1
|
||
|
|
[d0.5.1]: https://github.com/aseemk/json5/compare/v0.5.0...v0.5.1
|
||
|
|
|
||
|
|
This release includes a minor fix for indentations when stringifying empty
|
||
|
|
arrays.
|
||
|
|
|
||
|
|
- Fix: Indents no longer appear in empty arrays when stringified. ([#134])
|
||
|
|
|
||
|
|
|
||
|
|
### v0.5.0 [[code][c0.5.0], [diff][d0.5.0]]
|
||
|
|
|
||
|
|
[c0.5.0]: https://github.com/aseemk/json5/tree/v0.5.0
|
||
|
|
[d0.5.0]: https://github.com/aseemk/json5/compare/v0.4.0...v0.5.0
|
||
|
|
|
||
|
|
This release includes major internal changes and public API enhancements.
|
||
|
|
|
||
|
|
- **Major:** JSON5 officially supports Node.js v4 LTS and v5. Support for
|
||
|
|
Node.js v0.6 and v0.8 have been dropped, while support for v0.10 and v0.12
|
||
|
|
remain.
|
||
|
|
|
||
|
|
- Fix: YUI Compressor no longer fails when compressing json5.js. ([#97])
|
||
|
|
|
||
|
|
- New: `parse` and the CLI provide line and column numbers when displaying error
|
||
|
|
messages. ([#101]; awesome work by [@amb26].)
|
||
|
|
|
||
|
|
|
||
|
|
### v0.4.0 [[code][c0.4.0], [diff][d0.4.0]]
|
||
|
|
|
||
|
|
[c0.4.0]: https://github.com/aseemk/json5/tree/v0.4.0
|
||
|
|
[d0.4.0]: https://github.com/aseemk/json5/compare/v0.2.0...v0.4.0
|
||
|
|
|
||
|
|
Note that v0.3.0 was tagged, but never published to npm, so this v0.4.0
|
||
|
|
changelog entry includes v0.3.0 features.
|
||
|
|
|
||
|
|
This is a massive release that adds `stringify` support, among other things.
|
||
|
|
|
||
|
|
- **Major:** `JSON5.stringify()` now exists!
|
||
|
|
This method is analogous to the native `JSON.stringify()`;
|
||
|
|
it just avoids quoting keys where possible.
|
||
|
|
See the [usage documentation](./README.md#usage) for more.
|
||
|
|
([#32]; huge thanks and props [@aeisenberg]!)
|
||
|
|
|
||
|
|
- New: `NaN` and `-NaN` are now allowed number literals.
|
||
|
|
([#30]; thanks [@rowanhill].)
|
||
|
|
|
||
|
|
- New: Duplicate object keys are now allowed; the last value is used.
|
||
|
|
This is the same behavior as JSON. ([#57]; thanks [@jordanbtucker].)
|
||
|
|
|
||
|
|
- Fix: Properly handle various whitespace and newline cases now.
|
||
|
|
E.g. JSON5 now properly supports escaped CR and CRLF newlines in strings,
|
||
|
|
and JSON5 now accepts the same whitespace as JSON (stricter than ES5).
|
||
|
|
([#58], [#60], and [#63]; thanks [@jordanbtucker].)
|
||
|
|
|
||
|
|
- New: Negative hexadecimal numbers (e.g. `-0xC8`) are allowed again.
|
||
|
|
(They were disallowed in v0.2.0; see below.)
|
||
|
|
It turns out they *are* valid in ES5, so JSON5 supports them now too.
|
||
|
|
([#36]; thanks [@jordanbtucker]!)
|
||
|
|
|
||
|
|
|
||
|
|
### v0.2.0 [[code][c0.2.0], [diff][d0.2.0]]
|
||
|
|
|
||
|
|
[c0.2.0]: https://github.com/aseemk/json5/tree/v0.2.0
|
||
|
|
[d0.2.0]: https://github.com/aseemk/json5/compare/v0.1.0...v0.2.0
|
||
|
|
|
||
|
|
This release fixes some bugs and adds some more utility features to help you
|
||
|
|
express data more easily:
|
||
|
|
|
||
|
|
- **Breaking:** Negative hexadecimal numbers (e.g. `-0xC8`) are rejected now.
|
||
|
|
While V8 (e.g. Chrome and Node) supported them, it turns out they're invalid
|
||
|
|
in ES5. This has been [fixed in V8][v8-hex-fix] (and by extension, Chrome
|
||
|
|
and Node), so JSON5 officially rejects them now, too. ([#36])
|
||
|
|
|
||
|
|
- New: Trailing decimal points in decimal numbers are allowed again.
|
||
|
|
(They were disallowed in v0.1.0; see below.)
|
||
|
|
They're allowed by ES5, and differentiating between integers and floats may
|
||
|
|
make sense on some platforms. ([#16]; thanks [@Midar].)
|
||
|
|
|
||
|
|
- New: `Infinity` and `-Infinity` are now allowed number literals.
|
||
|
|
([#30]; thanks [@pepkin88].)
|
||
|
|
|
||
|
|
- New: Plus signs (`+`) in front of numbers are now allowed, since it can
|
||
|
|
be helpful in some contexts to explicitly mark numbers as positive.
|
||
|
|
(E.g. when a property represents changes or deltas.)
|
||
|
|
|
||
|
|
- Fix: unescaped newlines in strings are rejected now.
|
||
|
|
([#24]; thanks [@Midar].)
|
||
|
|
|
||
|
|
|
||
|
|
### v0.1.0 [[code][c0.1.0], [diff][d0.1.0]]
|
||
|
|
|
||
|
|
[c0.1.0]: https://github.com/aseemk/json5/tree/v0.1.0
|
||
|
|
[d0.1.0]: https://github.com/aseemk/json5/compare/v0.0.1...v0.1.0
|
||
|
|
|
||
|
|
This release tightens JSON5 support and adds helpful utility features:
|
||
|
|
|
||
|
|
- New: Support hexadecimal numbers. (Thanks [@MaxNanasy].)
|
||
|
|
|
||
|
|
- Fix: Reject octal numbers properly now. Previously, they were accepted but
|
||
|
|
improperly parsed as base-10 numbers. (Thanks [@MaxNanasy].)
|
||
|
|
|
||
|
|
- **Breaking:** Reject "noctal" numbers now (base-10 numbers that begin with a
|
||
|
|
leading zero). These are disallowed by both JSON5 and JSON, as well as by
|
||
|
|
ES5's strict mode. (Thanks [@MaxNanasy].)
|
||
|
|
|
||
|
|
- New: Support leading decimal points in decimal numbers.
|
||
|
|
(Thanks [@MaxNanasy].)
|
||
|
|
|
||
|
|
- **Breaking:** Reject trailing decimal points in decimal numbers now. These
|
||
|
|
are disallowed by both JSON5 and JSON. (Thanks [@MaxNanasy].)
|
||
|
|
|
||
|
|
- **Breaking:** Reject omitted elements in arrays now. These are disallowed by
|
||
|
|
both JSON5 and JSON.
|
||
|
|
|
||
|
|
- Fix: Throw proper `SyntaxError` instances on errors now.
|
||
|
|
|
||
|
|
- New: Add Node.js `require()` hook. Register via `json5/lib/require`.
|
||
|
|
|
||
|
|
- New: Add Node.js `json5` executable to compile JSON5 files to JSON.
|
||
|
|
|
||
|
|
|
||
|
|
### v0.0.1 [[code][c0.0.1], [diff][d0.0.1]]
|
||
|
|
|
||
|
|
[c0.0.1]: https://github.com/aseemk/json5/tree/v0.0.1
|
||
|
|
[d0.0.1]: https://github.com/aseemk/json5/compare/v0.0.0...v0.0.1
|
||
|
|
|
||
|
|
This was the first implementation of this JSON5 parser.
|
||
|
|
|
||
|
|
- Support unquoted object keys, including reserved words. Unicode characters
|
||
|
|
and escape sequences sequences aren't yet supported.
|
||
|
|
|
||
|
|
- Support single-quoted strings.
|
||
|
|
|
||
|
|
- Support multi-line strings.
|
||
|
|
|
||
|
|
- Support trailing commas in arrays and objects.
|
||
|
|
|
||
|
|
- Support comments, both inline and block.
|
||
|
|
|
||
|
|
|
||
|
|
### v0.0.0 [[code](https://github.com/aseemk/json5/tree/v0.0.0)]
|
||
|
|
|
||
|
|
Let's consider this to be Douglas Crockford's original [json_parse.js] — a
|
||
|
|
parser for the regular JSON format.
