Breaking changes
hoverTooltip
's callback function now takes a position and a side, rather than a predicate function, to determine whether a tooltip should be shown.
The highlightStyle
function, which defines a highlight style, is now called HighlightStyle.define
.
completeSnippets
no longer exists. Use completeFromList
in combination with snippetCompletion
.
The ...Support
functions that some language packages exported are gone, since it is now possible to get the support extensions directly from the package's main function.
The language
facet now returns an optional single language, not an array anymore.
Languages no longer have getTree
and ensureTree
methods.
keymap
is now a facet, rather than a function, which means you have to use it with keymap.of(...)
.
The markers
option to gutters now takes a view, rather than a state, as argument.
The completionKeymap
array now contains more default bindings.
Removes support for Text.iterLines
.
Line
objects no longer have slice
and findClusterBreak
methods (use text
and the top-level findClusterBreak
function instead).
EditorSelection.primary
is now called EditorSelection.main
.
rectangularSelection
now takes its configuration as an object.
A state field's provide
option works differently. It now takes a function from the field to an extension. Facet.from
has been changed to make it easy to use with this option.
To set an extension's precedence, use the properties of the Prec
object instead of the old precedence
function.
ViewUpdate.prevState
has been renamed to startState
.

objects now have a parseString
method that can be used to synchronously parse a string of code in that language.
When configuring an XML schema, it is now possible to provide text to complete into a given element.

@codemirror/next 0.15.0 (2020-12-04)
Breaking changes
The highlighting system no longer has the concept of a tag system—rather, all tags now exist in the same space.
Highlighting tags are now represented by objects (with the default tag system under tags
in the highlight package) rather than strings.
Highlighting styles are now registered separately from the actual highlighter plugin. Syntax addons take care of registering the highlighter. Styles are defined with the highlightStyle
function.
The syntax
package no longer exists. Its responsibilities have been taken over by the language
package.
Language and syntax-related functionality that used to live in the state
package (the syntax provider type, props like indentation
and foldable
) has been moved to the language
package.
The stream-syntax
package has been renamed to stream-parser
, and its interface has been changed to make use of the abstractions provided by the language
package.
Providing language data now works differently (the globalLanguageData
facet is gone, replaced by a more general languageData
facet).

methods on block widgets.
Prevent drawSelection

A text cursor created with Text.iterLines
now actually respects the skip parameter.
New Features
The language
package now provides most language and parsing related infrastructure. Unlike the old syntax
package, it is parse-technique-agnostic. Some of the interfaces that used to live in state
, such as the facets and types involved in indentation and folding, have also moved there.
The function passed to changeByRange
may now also return effects for each range.
The new State.transactionExtender
facet allows you to register functions that add annotations, effects, or reconfiguration to transactions even when they have disabled regular transaction filters.
The new lang-markdown
package provides Markdown highlighting.
The foldable
function exported from the language package provides an easy way to check whether a given line is foldable.
The getIndentation
utility from the language package should now be used to compute automatic indentation for a line. It returns null, as opposed to -1, to indicate that it has no indentation for a given line.
@codemirror/next 0.14.0 (2020-10-23)

Breaking changes
Themes are now specified differently, using plain CSS selectors extended with $
syntax for targeting theme classes. This should make them more flexible.
The style-mod dependency has been upgraded to 3.0, which is a backward-incompatible upgrade.
The multipleSelections
extension is no longer supported. You probably want to use drawSelection
combined with EditorState.allowMultipleSelections.of(true)
.
WidgetType
no longer takes a type parameter. Implementations are now themselves responsible for creating instance variables and implementing an appropriate eq
method.
Drops support for PluginValue.measure
(which was very broken already in the previous release).

property indicating whether IME is active.
The autocomplete package now exports acceptCompletion
and moveCompletionSelection
commands.
@codemirror/next 0.12.0 (2020-09-11)
Breaking changes
The way overlapping mark decorations are handled has changed. The editor will now create a separate element for each decoration, and nested them in order of the predecence of the sources that created them (higher precedence wrapping lower precedence, decorations from the state facet wrapping decorations from view plugins).
Registering decorations, event handlers, or other plugin values for a view plugin is now done differently (with an argument to ViewPlugin.define
or ViewPlugin.fromClass
, rather than method calls on the returned value).
Bug fixes
Vertical cursor motion when the selection isn't empty will now properly collapse it to the appropriate side, rather than moving from the selection head.
Fix the activateOnTyping
option to the autocomplete system.
The default backspace binding now deletes by code point, not character.
Tooltips are no longer cut off by scrollable parent elements.

View plugins can now provide a measure
method that gets called when the view measures itself.
@codemirror/next 0.11.0 (2020-09-03)
Breaking changes
Autocompletion contexts no longer have a filter
method. Completion sources shouldn't filter anymore, but leave that to the plugin.
The filterDownOn
property on completion results is now called span
.
AutocompleteContext.tokenBefore
now takes a list of token type names, and only returns tokens of those types. (In its previous form, it was too error-prone.)
Snippet specs no longer support a name
property (use detail
instead).
A number of exports from the autocomplete plugin were renamed: autocomplete
to autocompletion
, AutocompleteContext
to CompletionContext
, Autocompleter
to CompletionSource
.
SnippetSpec
objects are now a subclass of Completion
(which mostly means that their keyword
property was renamed to label
).
Bug fixes
Fix issue that could cause crashes or incorrectly mapped selections in the history when making changes with addToHistory
set to false.
Fuzzy completion matching got a lot more clever, and presents results ordered by match quality.
New features
Text copied linewise will now be inserted as lines above the selection when pasted into an empty selection.
The completion list now shows the matched parts of the strings.

and currentCompletions
, that let external code query its state.
A new method matchBefore
on the autocompletion context can now be used to easily find the text matching a given regexp before the cursor.
Completion contexts now have aborted
and addEventListener(abort, ...)
properties to allow asynchronous completion queries to stop doing work when cancelled.
Completions now support a detail
property to add some extra text after their label.

property to influence the way they are sorted compared to other completions that match the input equally well.
Completions can now have an info
property that provides extra information to be shown next to the completion when it is selected.

now has a toJSON
method and a static fromJSON
method to serialize to and deserialize from JSON.

property on transactions has been renamed to reconfigure
. Similarly, the scrolledIntoView
property is now called scrollIntoView
.

property.
Bug fixes
Fix an issue where language data at the end of an unfinished nested grammar at the end of the document would use the outer language instead of the inner.
New features
A LezerSyntax
instance can now specify a dialect to parse.
Transactions now have a newDoc
property that allows you to access the updated document before the new state has been created.
The indentString
property on editor states can be used to compute an indentation string of a given column width.
The view package now exports an indentOnInput
extension that enables automatic reindentation when certain patterns are typed at the start of a line. The basic setup enables this.
When the cursor is between matching brackets, insertNewlineAndIndent
will insert an additional newline after the cursor.
Transaction specs now support a sequential
property, which causes them to be interpreted in the document space as produced by earlier specs.
@codemirror/next 0.9.0 (2020-07-30)

fails to update the view.
Fix an issue where double-clicking on a selection in Chrome would leave you with just a cursor, not a selected word.
New features

) can now prefix tag names with !
to make them override the styling of any child nodes for that syntax node.
It is now possible, when specifying syntax highlighting information, to write rules for a node that apply only when its parent nodes are of a given type. This uses /
syntax, as in "Declaration/Identifier": "className"
.
Completion items can now specify a type
property that determines the icon shown next to them.
EditorView.inputHandler
can now be used to override the way text input (via the DOM) is handled.
The closebrackets
package now exports its backspace behavior as a command (deleteBracketPair
) and a set of bindings that bind it to backspace as closeBracketsKeymap
.
@codemirror/next 0.8.0 (2020-06-29)
Breaking changes
closeBrackets
is now a function, rather than an extension value.
The keymap, special-chars, and multiple-selections packages have been merged into the view package.
The way tooltips are declared changed somewhat to fix an issue with tooltips that stay active across document changes.

now returns a Text
, and there's a new append
method.
The representation of changes and change sets has been redone. Instead of storing a sequence of change objects, change sets are now a flat map of the locations in the document that changed.
The way transactions work has changed. They are now immutable objects created with EditorState.update
.
Transaction filtering works differently now. See the changeFilter
and transactionFilter
facets.
What used to be extension groups is now called tagged extensions (using the tagExtension
function).
mapPos
now returns -1 to indicate deletion (when the map mode asks for this).

Breaking changes
EditorView.domEventHandlers
is now a function, and the handlers receive their arguments in a different order.
Syntax objects no longer have a languageDataAt
method (this was moved to EditorState
, and changed somewhat).
Completion functions now return a plain list of results, rather than an object.
The interface to EditorState.indentation
changed, taking an IndentContext
object.
Facets provided by a state field are now declared in an option to StateField.define
, instead of in method calls on the field object.
Isolating transactions so that they become their own undo history item is now done with the isolateHistory
annotation.
The packages are no longer available as CommonJS files. To run the code on node.js, you'll need node 13 or pass --experimental-modules
to node 12.
New features
View plugins now have an eventHandlers
method to attach plugin-specific DOM event handlers.
The editor state now has a languageDataAt
that collects values stored under a given property name in the main language data and in object attached for a given document type with the addLanguageData
facet.
It is now possible to provide indentation functions with information about already-reindented lines through an IndentContext
object, making it possible to reindent a region in one go without re-parsing.
Lint sources can now be asynchronous.
The EditorView.editable
facet can now be used to control whether the content is editable.
The selectionFilter
facet can now be used to control selection updates.
The new changeFilter
facet can be used to stop or modify document changes.
Transaction.change
now also accepts an array of changes to apply in one go.
The history module now exports a facet that allows you to create inverted effects from a transaction, which will be stored in the history. (This allows making non-document state un/redoable.)
Transactions can now contains state effects, which can describe state changes for extensions, and be integrated with the undo history.
Transactions now have a mapRef
method to easily create a position mapping from a given intermediate document to the current document.
@codemirror/next 0.4.0 (2020-02-21)
Breaking Changes
Behavior was renamed to Facet
, and works somewhat differently.
The extension
package no longer exists. Extension-related concepts are now part of the state
package.
The view no longer has its own extension system. It is entirely configured by state extensions.
View plugins are specified through a state facet now, and have a simpler interface.
View plugins may no longer create decorations that significantly impact the height of content, to avoid the cyclic dependency between plugin decorations and the viewport.
Themes work differently now, using static CSS classes on DOM elements so that plugins don't have to update their DOM when the editor theme changes.
Highlighting token types now support a numeric suffix, which replaces the old typeN
modifiers.
The interface to syntax extensions and parse trees changed.
The way transaction annotations work was simplified a bit.
Range sets were rewritten and support a somewhat different interface now.
The way decorations are created now separates the creation of the decoration value from the creation of the range to which it should apply.
New features
State facets can provide decorations now.
Reading DOM layout information and similar things is now done with the requestMeasure
method.
Facets now explicitly track which fields and other facets they depend on, so that they are recomputed only when necessary.
Any object that has an extension
property that holds an extension value may now be used as an extension.
Overlong lines that are inside the viewport will now be partially hidden to speed up rendering and interaction.
The editor view now has a textDirection
property telling you whether the main writing direction is left-to-right or right-to-left.
There's now a visibleRanges
property that tells you which part of the viewport is actually going to be drawn, speeding up things like highlighting when there's large amounts of collapsed code in the viewport.
Bug fixes
Fix issue where mouse dragging would create selections with the the anchor and head reversed.
Make code folding behave better when the folded node doesn't start on the same line as the actual fold.
Fix a number of issues that would make parsing big files slow (or even lock up entirely).
@codemirror/next 0.3.0 (2019-11-29)
Breaking changes
Language-wide configuration is no longer stored in per-extension node props, but in a single languageData
object held in a prop defined in the state package. The Syntax
method languageDataAt
is used to read it.
Unique extensions no longer exist. Instead, extensions are deduplicated by identity. Merging configurations for an extension should now be done in a behavior.
Bug fixes
Fix issue where starting with an empty editor would break height estimates.
Fix an issue where widgets at the end of a line could stay around after being deleted in some cases.
Fix rendering of lines that are empty except for a widget.
New features
A plugin's drawMeasured
method may now return true to request another measure/draw cycle.
The editor view now has a requireMeasure
method to schedule a layout check that'll allow plugins to measure and update the DOM.
The state package now re-exports the Text
type.
Add an adaptor for connecting ESLint output to the CodeMirror linter package to the lang-javascript package.
The tooltip
package provides a way to show tooltip over the editor.
The new autocomplete
package implements an autocompletion interface.
The new lint
package integrates linting with the editor by underlining issues and providing a list of problems that you can scroll through.
The lang-javascript
package now exports an esLint
function that can be used to wire up ESLint to the CodeMirror lint integration.
@codemirror/next 0.2.0 (2019-10-28)
Breaking changes
syntaxIndentation
no longer has to be registered separately as an extension. It is now implied when registering a tree syntax.
The configuration passed to gutter
no longer takes direct class names, but a style
option that determines the theme fields used for the gutter.
ViewPlugin
instances are now created with a static create
method, instead of the constructor.
Declaring custom gutters is now done with a Gutter
constructor.
Configuring whether the gutters are fixed is now done with the gutters
extension, rather than per individual gutter.
There is now an additional wrapper element around the editor (EditorView.scrollDOM
), which is the element that should be targeted with overflow
style properties.
EditorView.cssClass
no longer accepts space-separated lists of classes.
Slot
from the extension package has been replaced with Annotation
in the state package. Transaction metadata is now called annotations, and the method names have been updated accordingly.
Command
from state was renamed to StateCommand
, ViewCommand
from view is now called Command
.
Bug fixes
Fix a bug where a behavior's combine
method wasn't called when the behavior was entirely static.
Fix issue that caused nested replaced decorations to be drawn incorrectly.
ViewUpdate.themeChanged
no longer returns the inverse of what it should be returning.
Avoid crash on Firefox when focusing the editor if another form field has focus.
Fixes a bug where changes near replacing decorations would corrupt the editor's view of its height layout.
New features
The new EditorState.foldable
behavior provides a way to register code folding services.
Lezer syntax can now register code folding metadata on tree nodes via foldNodeProp
.
There is now a fold package with code folding commands (which need the codeFolding
extension to be active to work).
EditorView.posFromDOM
can now be used to find the document position of a given DOM position.
Gutters can now be themed.
ViewPlugin
instances can be extended with dynamic behavior using their behavior
and decorations
methods.
Gutters can now be passed a handleDOMEvents
option that allows client code to register event handlers on them.
You can now iterate over a RangeSet
more cheaply with an (internal) iterator using the between
method.
Syntax services now have a docTypeAt
method that gives you the grammar node around the given point (which may be part of a nesting grammar).
The text package now has replacements for codePointAt
and fromCodePoint
.
Added a bracket-closing extension in the closebrackets
package.
Adds a panel package that contains functionality for showing UI panels at the top or bottom of the editor.
The new search package provides search/replace-related functionality.
Themes and EditorView.cssClass
can now target dot-separated more specific versions of a name.
The phrase
method on the editor view can now be used to access translation provided with the EditorView.phrases
behavior.
Widget toDOM
methods are now passed the editor view.
Add EditorView.scrollMargins
behavior, which can be used to make the view scroll past regions at the side of the editor when scrolling something into view.
The keymap package now exports a NormalizedKeymap
class that can be used to build key handlers on other elements.
