1.0.0-alpha.31 (July 11, 2019)
- Bumped
mdn/data
to2.0.4
(#99) - Lexer
- Added bracketed range notation support and related refactoring
- Removed
<number-zero-one>
,<number-one-or-greater>
and<positive-integer>
from generic types. In fact, types moved to patch, because those types can be expressed in a regular grammar due to bracketed range notation implemented - Added support for multiple token string matching
- Improved
<custom-ident>
production matching to claim the keyword only if no other unfulfilled production can claim it (#101) - Improved
<length>
production matching to claim "unitless zero" only if no other unfulfilled production can claim it - Changed lexer's constructor to prevent generic types override when used
- Fixed large
||
- and&&
-group matching, matching continues from the beginning on term match (#85) - Fixed checking that value has
var()
occurrences when value is a string (such values can't be matched on syntax currently and fail with specific error that can be used for ignorance in validation tools) - Fixed
<declaration-value>
and<any-value>
matching when a value contains a function, parentheses or braces

- Canceled error for unclosed
Brackets
,Function
andParentheses
when EOF is reached - Fixed error when prelude ends with a comment for at-rules with custom prelude consumer
- Relaxed at-rule parsing:
- Canceled error when EOF is reached after a prelude
- Canceled error for an at-rule with custom block consumer when at-rule has no block (just don't apply consumer in that case)
- Canceled error on at-rule parsing when it occurs outside prelude or block (at-rule is converting to
Raw
node) - Allowed for any at-rule to have a prelude and a block, even if it's invalid per at-rule syntax (the responsibility for this check is moved to lexer, since it's possible to construct a AST with such errors)
- Made a declaration value a safe parsing point (i.e. error on value parsing lead to a value is turning into
Raw
node, not a declaration as before) - Excluded surrounding white spaces and comments from a
Raw
node that represents a declaration value - Changed
Value
parse handler to return a node only with typeValue
(previously it returned aRaw
node in some cases) - Fixed issue with
onParseError()
is not invoked for errors occured on selector or declaration value parsing in some cases - Changed using of
onParseError()
to stop parsing if handler throws an exception

handler - Fixed raw consuming in tolerant mode when selector is invalid (greedy consuming and redundant warnings)
- Fixed exception in tolerant mode caused by unknown at-rule with unclosed block
- Changed handling of semicolons:
- Hanging semicolon inside declaration blocks raise an error or turns into a
Raw
node in tolerant mode instead of being ignored - Semicolon outside of declaration blocks opens a
Rule
node as part of selector instead of being ignored
- Hanging semicolon inside declaration blocks raise an error or turns into a

's false positive balance match to the end of input in some cases (#56) - Rename walker's entry point methods to be the same as CSSTree exposed methods (i.e.
walk()
,walkUp()
etc) - Rename at-rule's
expression
toprelude
(since spec names it so)AtruleExpression
node type →AtrulePrelude
Atrule.expression

node builds inparser#Raw()
function only - Changed semantic of
parser#Raw()
, it takes 5 parameters now (it might to be changed in future) - Changed
parser#tolerantParse()
to pass a start token index to fallback function instead of source offset - Fixed

toTokenizer.TYPE.WhiteSpace
- Renamed
Tokenizer.findWhitespaceEnd()
toTokenizer.findWhiteSpaceEnd()
- Added
- Parser
- Added initial implementation of tollerant mode (turn on by passing
tolerant: true
option). In this mode parse errors are never occour and any invalid part of CSS turns into aRaw
node. Current safe points:Atrule
,AtruleExpression
,Rule

. Feature is experimental and further improvements are planned. - Changed
Atrule.expression
to contain aAtruleExpression
node ornull
only (other node types is wrapping into aAtruleExpression
node) - Renamed
AttributeSelector.operator
toAttributeSelector.matcher
- Added initial implementation of tollerant mode (turn on by passing
- Generator
translate()
method is now can take a function as second argument, that recieves every generated chunk. When no function is passed, default handler is used, it concats all the chunks and method returns a string.

term (return thisGroup

- Changed
Lexer#matchProperty()
andLexer#matchType()
to return an object instead of match tree. A match tree stores inmatched

,isType()
,isProperty()
andisKeyword()

::slotted(<compound-selector>)
- Implemented
Brackets
node type - Implemented basic support for at-rule inside rule block (#24)
- Renamed
Selector
node type toSelectorList
- Renamed
SimpleSelector
node type toSelector
- Renamed
UnicodeRange.name
property toUnicodeRange.value
- Replaced
Negation
node type for regularPseudoClass
- Unified name of node property to store nested nodes, it always
children
now:StyleSheet.rules
->StyleSheet.children
SelectorList.selectors
->SelectorList.children
Block.declarations
->Block.children
*.sequence
->*.children
- Fixed edge cases in parsing
Hex
andUnicodeRange
when number not an integer - Changed
nth-
pseudos parsing- Implemented
An+B
node type to represent expressions like2n + 1
or-3n
- Fixed edge cases when
a
orb
is not an integer - Changed
odd
andeven
keywords processing, keywords are storing asIdentifier
node type now - Changed
Nth
node type format to store anth
-query and an optionalselector
- Implemented
of
clause fornth-
pseudos (a.e.:nth-child(2n + 1 of li, img)
) - Limited
Nth
parsing rules to:nth-child()
,:nth-last-child()
,:nth-of-type()
and:nth-last-of-type()
pseudos
- Implemented
- Changed the way to store locations
- Renamed
info
node property toloc
- Changed format of
loc
to storestart
andend
positions
- Renamed
1.0.0-alpha10 (January 11, 2017)
- Reworked
Scanner
to be a single point to its functionality - Exposed
Scanner
class to be useful for external projects - Changed
walk()
function behaviour to traverse AST nodes in natural order - Implemented
walkUp()
function to traverse AST nodes from deepest to parent (behaves aswalk()
before)
1.0.0-alpha9 (December 21, 2016)
- Fixed
<angle>
generic according to specs that allow a<number>
equals to zero to be used as valid value (#30)
1.0.0-alpha8 (November 11, 2016)
- Fixed
Scanner#skip()
issue method when cursor is moving to the end of source - Simplified
Progid
node - Changed behaviour for bad selector processing, now parsing fails instead of selector ignoring
- Fixed
<id-selector>
generic syntax - Added
q
unit for<length>
generic syntax - Refactored syntax parser (performance)
- Reduced startup time by implementing lazy syntax parsing (default syntax doesn't parse on module load)
- Updated syntax dictionaries and used
mdn/data
instead ofTemplate:CSSData
- Renamed
syntax.stringify()
method tosyntax.translate()
- Simplified generic syntax functions, those functions receive a single AST node for checking and should return
true
orfalse
- Added exception for values that contains
var()
, those values are always valid for now - Added more tests and increase code coverage to
98.5%
1.0.0-alpha7 (October 7, 2016)
- Added support for explicit descendant combinator (
>>
) - Implemented
Type
andUniversal
type nodes - Improved
Number
parsing by including sign and exponent (#26) - Parse
before
,after
,first-letter
andfirst-line
pseudos with single colon asPseudoElement
- Changed
FunctionalPseudo
node type toPseudoClass
- Fixed attribute selector name parsing (namespace edge cases)
- Fixed location calculation for specified offset when
eof
is reached - Added more non-standard colors (#25)
- Removed obsolete
Syntax#getAll()
method - Fixed various edge cases, code clean up and performance improvements
1.0.0-alpha6 (September 23, 2016)
- More accurate positions for syntax mismatch errors
- Added
apple
specific font keywords (#20) - Changed
Property
node stucture from object to string - Renamed
Ruleset
node type toRule
- Removed
Argument
node type - Fixed
Dimension
andPercentage
position computation - Fixed bad selector parsing (temporary solution)
- Fixed location computation for CSS with very long lines that may lead to really long parsing with
positions:true
(even freeze) - Fixed
line
andcolumn
computation forSyntaxMatch
error - Improved performance of parsing and translation. Now CSSTree is under 10ms in PostCSS benchmark.
