Bug fixes

The highlightStyle function, which defines a highlight style, is now called HighlightStyle.define.

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 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).

Actually call ignoreEvent methods on block widgets.

Prevent drawSelection from also hiding the native selection in block widgets.

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.

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).

@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.

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.

The autocomplete package now exports two new functions, completionStatus 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.

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)

Breaking changes

The backspace behavior in the closebrackets package is no longer implicitly included in the extension returned by closeBrackets().

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.

Assigning precedences to extension is now done using a plain precedence function, rather than a class.

The new state is no longer passed to state field update functions (it is part of the transaction anyway now).

The start and end properties of Line have been renamed to from and to for consistency.

EditorView.lineAt is now called visualLineAt. Its second argument now defaults to 0.

EditorView.lineAtHeight is now called visualLineAtHeight.

The fillConfig utility is no longer part of the library (the library depends on Object.assign now, which provides a standard way to do the same thing).

Completion sources now get all their arguments as properties of the context object.

Language-specific data is now stored in a facet attached to the syntax object, rather than directly in a node prop.

Reconfiguring transactions are now specified in a slightly different way.

@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

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.

@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.

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.
