+Remove a leftover `console.log` in bracket closing code.
+

+[ [**WEBSITE**](https://codemirror.net/) | [**DOCS**](https://codemirror.net/docs/ref/#autocomplete) | [**ISSUES**](https://github.com/codemirror/dev/issues) | [**FORUM**](https://discuss.codemirror.net/c/next/) | [**CHANGELOG**](https://github.com/codemirror/autocomplete/blob/main/CHANGELOG.md) ]
+
+This package implements autocompletion for the
+[CodeMirror](https://codemirror.net/) code editor.
+
+The [project page](https://codemirror.net/) has more information, a
+number of [examples](https://codemirror.net/examples/) and the
+[documentation](https://codemirror.net/docs/).
+
+This code is released under an
+[MIT license](https://github.com/codemirror/autocomplete/tree/main/LICENSE).
+
+We aim to be an inclusive, welcoming community. To make that explicit,
+we have a [code of
+conduct](http://contributor-covenant.org/version/1/1/0/) that applies
+to communication around the project.
+
+## Usage
+
+```javascript
+import {EditorView} from "@codemirror/view"
+import {autocompletion} from "@codemirror/autocomplete"
+import {jsonLanguage} from "@codemirror/lang-json"
+
+const view = new EditorView({
+  parent: document.body,
+  extensions: [
+    jsonLanguage,
+    autocompletion(),
+    jsonLanguage.data.of({
+      autocomplete: ["id", "name", "address"]
+    })
+  ]
+})
+```
+
+This configuration will just complete the given words anywhere in JSON
+context. Most language modules come with more refined autocompletion
+built-in, but you can also write your own custom autocompletion
+[sources](https://codemirror.net/docs/ref/#autocomplete.CompletionSource)
+and associate them with your language this way.

+## 6.10.1 (2025-12-17)
+
+### Bug fixes
+
+Fix a bug where `copyLineDown` would leave the cursor on the wrong line when it was at the start of the line.
+
+## 6.10.0 (2025-10-23)
+
+### New features
+
+The new `deleteGroupForwardWin` command provides by-group forward deletion using the Windows convention.
+
+## 6.9.0 (2025-10-02)
+
+### Bug fixes
+
+Prevent the default behavior of backspace and delete keys, to prevent the browser from doing anything creative when there's nothing to delete.
+
+### New features
+
+Implement new `addCursorAbove` and `addCursorBelow` commands. Bind them to Mod-Alt-ArrowUp/Down in the default keymap.
+
+## 6.8.1 (2025-03-31)
+
+### Bug fixes
+
+Fix an issue where creating a comment for a line that starts an inner language would use the comment style from the outer language.
+
+## 6.8.0 (2025-01-08)
+
+### New features
+
+The new `cursorGroupForwardWin` and `selectGroupForwardWin` commands implement Windows-style forward motion by group.
+
+## 6.7.1 (2024-10-21)
+
+### Bug fixes
+
+Change `toggleBlockCommentByLine` to not affect lines with the selection end right at their start.
+
+## 6.7.0 (2024-10-07)
+
+### Bug fixes
+
+Bind Shift-Enter to the same command as Enter in the default keymap, so that it doesn't do nothing when on an EditContext-supporting browser.
+
+### New features
+
+Add commands for by-string-index cursor motion that ignores text direction.
+
+## 6.6.2 (2024-09-17)
+
+### Bug fixes
+
+Fix an issue causing `selectParentSyntax` to not select syntax that is a direct child of the top node.
+
+Make `selectParentSyntax` return false when it doesn't change the selection.
+
+## 6.6.1 (2024-08-31)
+
+### Bug fixes
+
+Fix a bug in the undo history that would cause it to incorrectly track inverted effects when adding multiple edits to a single history event.
+
+## 6.6.0 (2024-06-04)
+
+### New features
+
+The new `toggleTabFocusMode` and `temporarilySetTabFocusMode` commands provide control over the view's tab-focus mode.
+
+The default keymap now binds Ctrl-m (Shift-Alt-m on macOS) to `toggleTabFocusMode`.
+
+## 6.5.0 (2024-04-19)
+
+### New features
+
+The `insertNewlineKeepIndent` command inserts a newline along with the same indentation as the line before.
+
+## 6.4.0 (2024-04-17)
+
+### Bug fixes
+
+Fix an issue where `deleteLine` sometimes leaves the cursor on the wrong line.
+
+### New features
+
+The new `deleteCharBackwardStrict` command just deletes a character, without further smart behavior around indentation.
+
+## 6.3.3 (2023-12-28)
+
+### Bug fixes
+
+Fix an issue causing cursor motion commands to not dispatch a transaction when the change only affects cursor associativity.
+
+## 6.3.2 (2023-11-28)
+
+### Bug fixes
+
+Fix a regression that caused `deleteCharBackward` to sometimes delete a large chunk of text.
+
+## 6.3.1 (2023-11-27)
+
+### Bug fixes
+
+When undoing, store the selection after the undone change with the redo event, so that redoing restores it.
+
+`deleteCharBackward` will no longer delete variant selector characters as separate characters.
+
+## 6.3.0 (2023-09-29)
+
+### Bug fixes
+
+Make it possible for `selectParentSyntax` to jump out of or into a syntax tree overlay.
+
+Make Cmd-Backspace and Cmd-Delete on macOS delete to the next line wrap point, not the start/end of the line.
+
+### New features
+
+The new `deleteLineBoundaryForward` and `deleteLineBoundaryBackward` commands delete to the start/end of the line or the next line wrapping point.
+
+## 6.2.5 (2023-08-26)
+
+### Bug fixes
+
+Make `insertNewlineAndIndent` properly count indentation for tabs when copying over the previous line's indentation.
+
+The various sub-word motion commands will now use `Intl.Segmenter`, when available, to stop at CJK language word boundaries.
+
+Fix a bug in `insertNewlineAndIndent` that would delete text between brackets if it had no corresponding AST node.
+
+## 6.2.4 (2023-05-03)
+
+### Bug fixes
+
+The by-subword motion commands now properly treat dashes, underscores, and similar as subword separators.
+
+## 6.2.3 (2023-04-19)
+
+### Bug fixes
+
+Block commenting the selection no longer includes indentation on the first line.
+
+## 6.2.2 (2023-03-10)
+
+### Bug fixes
+
+Fix a bug where line commenting got confused when commenting a range that crossed language boundaries.
+
+## 6.2.1 (2023-02-15)
+
+### Bug fixes
+
+Keep cursor position stable in `cursorPageUp`/`cursorPageDown` when there are panels or other scroll margins active.
+
+Make sure `toggleComment` doesn't get thrown off by local language nesting, by fetching the language data for the start of the selection line.
+
+## 6.2.0 (2023-01-18)
+
+### New features
+
+The new `joinToEvent` history configuration option allows you to provide custom logic that determines whether a new transaction is added to an existing history event.
+
+## 6.1.3 (2022-12-26)
+
+### Bug fixes
+
+Preserve selection bidi level when extending the selection, to prevent shift-selection from getting stuck in some kinds of bidirectional text.
+
+## 6.1.2 (2022-10-13)
+
+### Bug fixes
+
+Fix a bug that caused deletion commands on non-empty ranges to incorrectly return false and do nothing, causing the editor to fall back to native behavior.
+
+## 6.1.1 (2022-09-28)
+
+### Bug fixes
+
+Make sure the selection endpoints are moved out of atomic ranges when applying a deletion command to a non-empty selection.
+
+## 6.1.0 (2022-08-18)
+
+### Bug fixes
+
+Prevent native behavior on Ctrl/Cmd-ArrowLeft/ArrowRight bindings, so that browsers with odd bidi behavior won't do the wrong thing at start/end of line.
+
+Cmd-ArrowLeft/Right on macOS now moves the cursor in the direction of the arrow even in right-to-left content.
+
+### New features
+
+The new `cursorLineBoundaryLeft`/`Right` and `selectLineBoundaryLeft`/`Right` commands allow directional motion to line boundaries.
+
+## 6.0.1 (2022-06-30)
+
+### Bug fixes
+
+Announce to the screen reader when the selection is deleted.
+
+Also bind Ctrl-Shift-z to redo on Linux.
+
+## 6.0.0 (2022-06-08)
+
+### Bug fixes
+
+Fix a bug where by-page selection commands sometimes moved one line too far.
+
+## 0.20.0 (2022-04-20)
+
+### Breaking changes
+
+There is no longer a separate `commentKeymap`. Those bindings are now part of `defaultKeymap`.
+
+### Bug fixes
+
+Make `cursorPageUp` and `cursorPageDown` move by window height when the editor is higher than the window.
+
+Make sure the default behavior of Home/End is prevented, since it could produce unexpected results on macOS.
+
+### New features
+
+The exports from @codemirror/comment are now available in this package.
+
+The exports from the @codemirror/history package are now available from this package.
+
+## 0.19.8 (2022-01-26)
+
+### Bug fixes
+
+`deleteCharBackward` now removes extending characters one at a time, rather than deleting the entire glyph at once.
+
+Alt-v is no longer bound in `emacsStyleKeymap` and macOS's `standardKeymap`, because macOS doesn't bind it by default and it conflicts with some keyboard layouts.
+
+## 0.19.7 (2022-01-11)
+
+### Bug fixes
+
+Don't bind Alt-\< and Alt-> on macOS by default, since those interfere with some keyboard layouts. Make cursorPageUp/Down scroll the view to keep the cursor in place
+
+`cursorPageUp` and `cursorPageDown` now scroll the view by the amount that the cursor moved.
+
+## 0.19.6 (2021-12-10)
+
+### Bug fixes
+
+The standard keymap no longer overrides Shift-Delete, in order to allow the native behavior of that key to happen on platforms that support it.
+
+## 0.19.5 (2021-09-21)
+
+### New features
+
+Adds an `insertBlankLine` command which creates an empty line below the selection, and binds it to Mod-Enter in the default keymap.
+
+## 0.19.4 (2021-09-13)
+
+### Bug fixes
+
+Make commands that affect the editor's content check `state.readOnly` and return false when that is true.
+
+## 0.19.3 (2021-09-09)
+
+### Bug fixes
+
+Make by-line cursor motion commands move the cursor to the start/end of the document when they hit the first/last line.
+
+Fix a bug where `deleteCharForward`/`Backward` behaved incorrectly when deleting directly before or after an atomic range.
+
+## 0.19.2 (2021-08-24)
+
+### New features
+
+New commands `cursorSubwordForward`, `cursorSubwordBackward`, `selectSubwordForward`, and `selectSubwordBackward` which implement motion by camel case subword.
+
+## 0.19.1 (2021-08-11)
+
+### Bug fixes
+
+Fix incorrect versions for @lezer dependencies.
+
+## 0.19.0 (2021-08-11)
+
+### Breaking changes
+
+Change default binding for backspace to `deleteCharBackward`, drop `deleteCodePointBackward`/`Forward` from the library.
+
+`defaultTabBinding` was removed.
+
+### Bug fixes
+
+Drop Alt-d, Alt-f, and Alt-b bindings from `emacsStyleKeymap` (and thus from the default macOS bindings).
+
+`deleteCharBackward` and `deleteCharForward` now take atomic ranges into account.
+
+### New features
+
+Attach more granular user event strings to transactions.
+
+The module exports a new binding `indentWithTab` that binds tab and shift-tab to `indentMore` and `indentLess`.
+
+## 0.18.3 (2021-06-11)
+
+### Bug fixes
+
+`moveLineDown` will no longer incorrectly grow the selection.
+
+Line-based commands will no longer include lines where a range selection ends right at the start of the line.
+
+## 0.18.2 (2021-05-06)
+
+### Bug fixes
+
+Use Ctrl-l, not Alt-l, to bind `selectLine` on macOS, to avoid conflicting with special-character-insertion bindings.
+
+Make the macOS Command-ArrowLeft/Right commands behave more like their native versions.
+
+## 0.18.1 (2021-04-08)
+
+### Bug fixes
+
+Also bind Shift-Backspace and Shift-Delete in the default keymap (to do the same thing as the Shift-less binding).
+
+### New features
+
+Adds a `deleteToLineStart` command.
+
+Adds bindings for Cmd-Delete and Cmd-Backspace on macOS.
+
+## 0.18.0 (2021-03-03)
+
+### Breaking changes
+
+Update dependencies to 0.18.
+
+## 0.17.5 (2021-02-25)
+
+### Bug fixes
+
+Use Alt-l for the default `selectLine` binding, because Mod-l already has an important meaning in the browser.
+
+Make `deleteGroupBackward`/`deleteGroupForward` delete groups of whitespace when bigger than a single space.
+
+Don't change lines that have the end of a range selection directly at their start in `indentLess`, `indentMore`, and `indentSelection`.
+
+## 0.17.4 (2021-02-18)
+
+### Bug fixes
+
+Fix a bug where `deleteToLineEnd` would delete the rest of the document when at the end of a line.
+
+## 0.17.3 (2021-02-16)
+
+### Bug fixes
+
+Fix an issue where `insertNewlineAndIndent` behaved strangely with the cursor between brackets that sat on different lines.
+
+## 0.17.2 (2021-01-22)
+
+### New features
+
+The new `insertTab` command inserts a tab when nothing is selected, and defers to `indentMore` otherwise.
+
+The package now exports a `defaultTabBinding` object that provides a recommended binding for tab (if you must bind tab).
+
+## 0.17.1 (2021-01-06)
+
+### New features
+
+The package now also exports a CommonJS module.
+
+## 0.17.0 (2020-12-29)
+
+### Breaking changes
+
+First numbered release.

+## 6.4.11 (2025-10-02)
+
+### Bug fixes
+
+Adjust autocompletion to work with @lezer/html's improved handling of `<` characters without tag name after them.
+
+## 6.4.10 (2025-09-11)
+
+### Bug fixes
+
+Don't include period characters in the language's word characters.
+
+## 6.4.9 (2024-04-12)
+
+### Bug fixes

+Complete attribute names after whitespace in a tag even when completion isn't explicitly triggered.
+
+## 6.4.7 (2023-11-27)
+
+### Bug fixes
+
+Parse `script` tags with `application/json` type as JSON syntax.
+
+## 6.4.6 (2023-08-28)
+
+### Bug fixes
+
+`autoCloseTags` now generates two separate transactions, so that the completion can be undone separately.
+
+Add highlighting for the content of `<script>` tags with a type of `importmap` or `speculationrules`.
+
+## 6.4.5 (2023-06-23)
+

+
+## 6.4.3 (2023-03-27)
+
+### Bug fixes
+
+Fix a bug that could cause some nested language regions to be parsed multiple times.
+
+## 6.4.2 (2023-02-10)
+
+### Bug fixes
+
+Fix an issue where `autoCloseTags` would close self-closing tags when typed directly in front of a word.

+Directly depend on @lang/css 1.1.0, since we're using a new top rule name introduced in that.
+
+### New features
+
+Add a `globalAttrs` property to (completion) `TagSpec` objects that controls whether global attributes are completed in that tag.
+
+## 6.3.1 (2022-11-29)
+
+### Bug fixes
+
+Remove incorrect pure annotation that broke the code after tree-shaking.
+
+## 6.3.0 (2022-11-28)

+Parse type=text/babel script tags as JSX.
+
+### New features
+
+The new `nestedLanguages` option can be used to configure how the content of script, style, and textarea tags is parsed.

+## Usage
+
+```javascript
+import {EditorView, basicSetup} from "codemirror"
+import {json} from "@codemirror/lang-json"
+
+const view = new EditorView({
+  parent: document.body,
+  doc: `{"version": "9.99.99", "data": [1, 2, 3]}`,

+### New features
+
+The new `bidiIsolates` extension can be used to wrap syntactic elements where this is appropriate in an element that isolates their text direction, avoiding weird ordering of neutral characters on direction boundaries.

+## 0.20.0 (2022-04-20)
+
+### Breaking changes
+
+`HighlightStyle.get` is now called `highlightingFor`.
+
+`HighlightStyles` no longer function as extensions (to improve tree shaking), and must be wrapped with `syntaxHighlighting` to add to an editor configuration.
+
+`Language` objects no longer have a `topNode` property.
+
+### New features
+
+`HighlightStyle` and `defaultHighlightStyle` from the now-removed @codemirror/highlight package now live in this package.
+
+The new `forceParsing` function can be used to run the parser forward on an editor view.
+
+The exports that used to live in @codemirror/matchbrackets are now exported from this package.
+
+The @codemirror/fold package has been merged into this one.
+
+The exports from the old @codemirror/stream-parser package now live in this package.
+
+## 0.19.10 (2022-03-31)
+
+### Bug fixes
+
+Autocompletion may now also trigger automatic indentation on input.
+
+## 0.19.9 (2022-03-30)
+
+### Bug fixes
+
+Make sure nodes that end at the end of a partial parse aren't treated as valid fold targets.
+
+Fix an issue where the parser sometimes wouldn't reuse parsing work done in the background on transactions.
+
+## 0.19.8 (2022-03-03)
+
+### Bug fixes
+
+Fix an issue that could cause indentation logic to use the wrong line content when indenting multiple lines at once.
+
+## 0.19.7 (2021-12-02)
+
+### Bug fixes
+
+Fix an issue where the parse worker could incorrectly stop working when the parse tree has skipped gaps in it.
+
+## 0.19.6 (2021-11-26)
+
+### Bug fixes
+
+Fixes an issue where the background parse work would be scheduled too aggressively, degrading responsiveness on a newly-created editor with a large document.
+
+Improve initial highlight for mixed-language editors and limit the amount of parsing done on state creation for faster startup.
+
+## 0.19.5 (2021-11-17)
+
+### New features
+
+The new function `syntaxTreeAvailable` can be used to check if a fully-parsed syntax tree is available up to a given document position.
+
+The module now exports `syntaxParserRunning`, which tells you whether the background parser is still planning to do more work for a given editor view.
+
+## 0.19.4 (2021-11-13)
+
+### New features
+
+`LanguageDescription.of` now takes an optional already-loaded extension.
+
+## 0.19.3 (2021-09-13)
+
+### Bug fixes
+
+Fix an issue where a parse that skipped content with `skipUntilInView` would in some cases not be restarted when the range came into view.
+
+## 0.19.2 (2021-08-11)
+
+### Bug fixes
+
+Fix a bug that caused `indentOnInput` to fire for the wrong kinds of transactions.
+
+Fix a bug that could cause `indentOnInput` to apply its changes incorrectly.
+
+## 0.19.1 (2021-08-11)
+
+### Bug fixes
+
+Fix incorrect versions for @lezer dependencies.
+
+## 0.19.0 (2021-08-11)
+
+### Breaking changes
+
+CodeMirror now uses lezer 0.15, which means different package names (scoped with @lezer) and some breaking changes in the library.
+
+`EditorParseContext` is now called `ParseContext`. It is no longer passed to parsers, but must be retrieved with `ParseContext.get`.
+
+`IndentContext.lineIndent` now takes a position, not a `Line` object, as argument.
+
+`LezerLanguage` was renamed to `LRLanguage` (because all languages must emit Lezer-style trees, the name was misleading).
+
+`Language.parseString` no longer exists. You can just call `.parser.parse(...)` instead.
+
+### New features
+
+New `IndentContext.lineAt` method to access lines in a way that is aware of simulated line breaks.
+
+`IndentContext` now provides a `simulatedBreak` property through which client code can query whether the context has a simulated line break.
+
+## 0.18.2 (2021-06-01)
+
+### Bug fixes
+
+Fix an issue where asynchronous re-parsing (with dynamically loaded languages) sometimes failed to fully happen.
+
+## 0.18.1 (2021-03-31)
+
+### Breaking changes
+
+`EditorParseContext.getSkippingParser` now replaces `EditorParseContext.skippingParser` and allows you to provide a promise that'll cause parsing to start again. (The old property remains available until the next major release.)
+
+### Bug fixes
+
+Fix an issue where nested parsers could see past the end of the nested region.
+
+## 0.18.0 (2021-03-03)
+
+### Breaking changes
+
+Update dependencies to 0.18.
+
+### Breaking changes
+
+The `Language` constructor takes an additional argument that provides the top node type.
+
+### New features
+
+`Language` instances now have a `topNode` property giving their top node type.
+
+`TreeIndentContext` now has a `continue` method that allows an indenter to defer to the indentation of the parent nodes.
+
+## 0.17.5 (2021-02-19)
+
+### New features
+
+This package now exports a `foldInside` helper function, a fold function that should work for most delimited node types.
+
+## 0.17.4 (2021-01-15)
+
+## 0.17.3 (2021-01-15)
+
+### Bug fixes

+Parse scheduling has been improved to reduce the likelyhood of the user looking at unparsed code in big documents.
+
+Prevent parser from running too far past the current viewport in huge documents.
+
+## 0.17.2 (2021-01-06)
+
+### New features
+
+The package now also exports a CommonJS module.
+
+## 0.17.1 (2020-12-30)
+
+### Bug fixes
+
+Fix a bug where changing the editor configuration wouldn't update the language parser used.
+
+## 0.17.0 (2020-12-29)
+
+### Breaking changes
+
+First numbered release.

+
+This package implements the language support infrastructure for the
+[CodeMirror](https://codemirror.net/) code editor.
+
+The [project page](https://codemirror.net/) has more information, a
+number of [examples](https://codemirror.net/examples/) and the
+[documentation](https://codemirror.net/docs/).
+
+This code is released under an
+[MIT license](https://github.com/codemirror/language/tree/main/LICENSE).
+
+We aim to be an inclusive, welcoming community. To make that explicit,
+we have a [code of
+conduct](http://contributor-covenant.org/version/1/1/0/) that applies
+to communication around the project.
+
+## Usage
+
+Setting up a language from a [Lezer](https://lezer.codemirror.net)
+parser looks like this:
+
+```javascript
+import {parser} from "@lezer/json"
+import {LRLanguage, continuedIndent, indentNodeProp,
+        foldNodeProp, foldInside} from "@codemirror/language"
+
+export const jsonLanguage = LRLanguage.define({
+  name: "json",
+  parser: parser.configure({
+    props: [
+      indentNodeProp.add({
+        Object: continuedIndent({except: /^\s*\}/}),
+        Array: continuedIndent({except: /^\s*\]/})
+      }),
+      foldNodeProp.add({
+        "Object Array": foldInside
+      })
+    ]
+  }),
+  languageData: {
+    closeBrackets: {brackets: ["[", "{", '"']},
+    indentOnInput: /^\s*[\}\]]$/
+  }
+})
+```
+
+Often, you'll also use this package just to access some specific
+language-related features, such as accessing the editor's syntax
+tree...
+
+```javascript
+import {syntaxTree} from "@codemirror/language"
+
+const tree = syntaxTree(view)
+```
+
+... or computing the appriate indentation at a given point.
+
+```javascript
+import {getIndentation} from "@codemirror/language"
+
+console.log(getIndentation(view.state, view.state.selection.main.head))
+```
