v2.1.2 [code, diff]
- Fix: Bump
minimist
tov1.2.5
. (#222)
v2.1.1 [code, diff]
- New:
package.json
andpackage.json5
include amodule
property so bundlers like webpack, rollup and parcel can take advantage of the ES Module build. (#208) - Fix:
stringify
outputs\0
as\\x00
when followed by a digit. (#210) - Fix: Spelling mistakes have been fixed. (#196)
v2.1.0 [code, diff]
- New: The
index.mjs
andindex.min.mjs
browser builds in thedist
directory support ES6 modules. (#187)
v2.0.1 [code, diff]
- Fix: The browser builds in the
dist
directory support ES5. (#182)
v2.0.0 [code, diff]
-
Major: JSON5 officially supports Node.js v6 and later. Support for Node.js v4 has been dropped. Since Node.js v6 supports ES5 features, the code has been rewritten in native ES5, and the dependence on Babel has been eliminated.
-
New: Support for Unicode 10 has been added.
-
New: The test framework has been migrated from Mocha to Tap.
-
New: The browser build at
dist/index.js
is no longer minified by default. A minified version is available atdist/index.min.js
. (#181) -
Fix: The warning has been made clearer when line and paragraph separators are used in strings.
-
Fix:
package.json5
has been restored, and it is automatically generated and committed when the version is bumped. A newbuild-package
NPM script has been added to facilitate this.
v1.0.1 [code, diff]
This release includes a bug fix and minor change.
-
Fix:
parse
throws on unclosed objects and arrays. -
New:
package.json5
has been removed until an easier way to keep it in sync withpackage.json
is found.
v1.0.0 [code, diff]
This release includes major internal changes and public API enhancements.
-
Major: JSON5 officially supports Node.js v4 and later. Support for Node.js v0.10 and v0.12 have been dropped.
-
New: Unicode property names and Unicode escapes in property names are supported. (#1)
-
New:
stringify
outputs trailing commas in objects and arrays when aspace
option is provided. (#66) -
New: JSON5 allows line and paragraph separator characters (U+2028 and U+2029) in strings in order to be compatible with JSON. However, ES5 does not allow these characters in strings, so JSON5 gives a warning when they are parsed and escapes them when they are stringified. (#70)
-
New:
stringify
accepts an options object as its second argument. The supported options arereplacer
,space
, and a newquote
option that specifies the quote character used in strings. (#71) -
New: The CLI supports STDIN and STDOUT and adds
--out-file
,--space
, and--validate
options. Seejson5 --help
for more information. (#72, #84, and #108) -
New: In addition to the white space characters space
\t
,\v
,\f
,\n
,\r
, and\xA0
, the additional white space characters\u2028
,\u2029
, and all other characters in the Space Separator Unicode category are allowed. -
New: In addition to the character escapes
\'
,\"
,\\
,\b
,\f
,\n
,\r
, and\t
, the additional character escapes\v
and\0
, hexadecimal escapes like\x0F
, and unnecessary escapes like\a
are allowed in string values and string property names. -
New:
stringify
outputs strings with single quotes by default but intelligently uses double quotes if there are more single quotes than double quotes inside the string. (i.e.stringify('Stay here.')
outputs'Stay here.'
whilestringify('Let\'s go.')
outputs"Let's go."
) -
New: When a character is not allowed in a string,
stringify
outputs a character escape like\t
when available, a hexadecimal escape like\x0F
when the Unicode code point is less than 256, or a Unicode character escape like\u01FF
, in that order. -
New:
stringify
checks for atoJSON5
method on objects and, if it exists, stringifies its return value instead of the object.toJSON5
overridestoJSON
if they both exist. -
New: To
require
orimport
JSON5 files, userequire('json5/lib/register')
orimport 'json5/lib/register'
. Previous versions usedjson5/lib/require
, which still exists for backward compatibility but is deprecated and will give a warning. -
New: To use JSON5 in browsers, use the file at
dist/index.js
orhttps://unpkg.com/json5@^1.0.0
. -
Fix:
stringify
properly outputsInfinity
andNaN
. (#67) -
Fix:
isWord
no longer becomes a property ofJSON5
after callingstringify
. (#68 and #89) -
Fix:
stringify
no longer throws when an object does not have aprototype
. (#154) -
Fix:
stringify
properly handles thekey
argument oftoJSON(key)
methods.toJSON5(key)
follows this pattern. -
Fix:
stringify
acceptsNumber
andString
objects as itsspace
argument. -
Fix: In addition to a function,
stringify
also accepts an array of keys to include in the output as itsreplacer
argument. Numbers,Number
objects, andString
objects will be converted to a string if they are given as array values.
v0.5.1 [code, diff]
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, diff]
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, diff]
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 nativeJSON.stringify()
; it just avoids quoting keys where possible. See the usage documentation 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, diff]
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 (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, diff]
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 viajson5/lib/require
. -
New: Add Node.js
json5
executable to compile JSON5 files to JSON.
v0.0.1 [code, diff]
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]
Let's consider this to be Douglas Crockford's original json_parse.js — a parser for the regular JSON format.
