Overview

TypeScript definitions for codemirror

Index

Variables

variable commands

const commands: CommandActions;

Commands are parameter-less actions that can be performed on an editor. Their main use is for key bindings. Commands are defined by adding properties to the CodeMirror.commands object.

variable defaults

const defaults: { [option: string]: any };

An object containing default values for all options. You can assign to its properties to modify defaults (though this won't affect editors that have already been created).

variable Doc

const Doc: DocConstructor;

variable fold

const fold: FoldHelpers;

variable hint

const hint: HintHelpers;

variable htmlSchema

const htmlSchema: any;

variable MergeView

const MergeView: MergeViewConstructor;

variable mimeModes

const mimeModes: MimeModeMap;

Maps MIME types to mode specs.

variable modeInfo

const modeInfo: ModeInfo[];

variable modes

const modes: ModeMap;

Maps mode names to their constructors

variable modeURL

let modeURL: string;

variable Pass

const Pass: { toString(): 'CodeMirror.PASS' };

variable Pos

const Pos: PositionConstructor;

variable scrollbarModel

const scrollbarModel: ScrollbarModels;

variable version

const version: string;

It contains a string that indicates the version of the library. This is a triple of integers "major.minor.patch", where patch is zero for releases, and something else (usually one) for dev snapshots.

Functions

function autoLoadMode

autoLoadMode: (
    instance: Editor,
    mode: string,
    options?: RequireModeOptions
) => void;

function changeEnd

changeEnd: (change: EditorChange) => Position;

Utility function that computes an end position from a change (an object with from, to, and text properties, as passed to various event handlers). The returned position will be the end of the changed range, after the change is applied.

function cmpPos

cmpPos: (a: Position, b: Position) => number;

Compare two positions, return 0 if they are the same, a negative number when a is less, and a positive number otherwise.

function CodeMirror

CodeMirror: typeof import('/index.d.ts');

function colorize

colorize: (collection?: ArrayLike<Element>, defaultMode?: string) => void;

Provides a convenient way to syntax-highlight code snippets in a webpage. Depends on the runmode addon (or its standalone variant). Can be called with an array (or other array-ish collection) of DOM nodes that represent the code snippets. By default, it'll get all pre tags. Will read the data-lang attribute of these nodes to figure out their language, and syntax-color their content using the relevant CodeMirror mode (you'll have to load the scripts for the relevant modes yourself). A second argument may be provided to give a default mode, used when no language attribute is found for a node.

function countColumn

countColumn: (line: string, index: number | null, tabSize: number) => number;

Find the column position at a given string index using a given tabsize.

function defineDocExtension

defineDocExtension: (name: string, value: any) => void;

Like defineExtension, but the method will be added to the interface for Doc objects instead.

function defineExtension

defineExtension: (name: string, value: any) => void;

If you want to define extra methods in terms of the CodeMirror API, it is possible to use defineExtension. This will cause the given value(usually a method) to be added to all CodeMirror instances created from then on.

function defineInitHook

defineInitHook: (func: (editor: Editor) => void) => void;

If your extension just needs to run some code whenever a CodeMirror instance is initialized, use CodeMirror.defineInitHook. Give it a function as its only argument, and from then on, that function will be called (with the instance as argument) whenever a new CodeMirror instance is initialized.

function defineMIME

defineMIME: (mime: string, modeSpec: string | ModeSpec<ModeSpecOptions>) => void;

function defineMode

defineMode: (id: string, modefactory: ModeFactory<any>) => void;

id will be the id for the defined mode. Typically, you should use this second argument to defineMode as your module scope function (modes should not leak anything into the global scope!), i.e. write your whole mode inside this function.

function defineOption

defineOption: (
    name: string,
    default_: any,
    updateFunc: (editor: Editor, val: any, old: any) => void
) => void;

Similarly, defineOption can be used to define new options for CodeMirror. The updateFunc will be called with the editor instance and the new value when an editor is initialized, and whenever the option is modified through setOption.

function defineSimpleMode

defineSimpleMode: <K extends string>(
    name: string,
    mode: { [P in K]: P extends 'meta' ? Record<string, any> : Rule[] } & {
        start: Rule[];
    }
) => void;

function extendMode

extendMode: (name: string, properties: Partial<Mode<any>>) => void;

Sometimes, it is useful to add or override mode object properties from external code. The CodeMirror.extendMode function can be used to add properties to mode objects produced for a specific mode. Its first argument is the name of the mode, its second an object that specifies the properties that should be added. This is mostly useful to add utilities that can later be looked up through getMode.

function findEnclosingTag

findEnclosingTag: (
    cm: Editor,
    pos: Position,
    range: Range,
    tag: string
) => { open: XmlTag; close: XmlTag } | undefined;

function findMatchingTag

findMatchingTag: (
    cm: Editor,
    pos: Position,
    range: Range
) =>
    | { open: XmlTag; close: XmlTag | null | undefined; at: 'open' | 'close' }
    | undefined;

function findModeByExtension

findModeByExtension: (ext: string) => ModeInfo | undefined;

function findModeByFileName

findModeByFileName: (filename: string) => ModeInfo | undefined;

function findModeByMIME

findModeByMIME: (mime: string) => ModeInfo | undefined;

function findModeByName

findModeByName: (name: string) => ModeInfo | undefined;

function fromTextArea

fromTextArea: (
    host: HTMLTextAreaElement,
    options?: EditorConfiguration
) => EditorFromTextArea;

function getMode

getMode: (
    config: EditorConfiguration,
    mode: string | ModeSpec<ModeSpecOptions>
) => Mode<unknown>;

The first argument is a configuration object as passed to the mode constructor function, and the second argument is a mode specification as in the EditorConfiguration mode option.

function innerMode

innerMode: (mode: Mode<any>, state: any) => { state: any; mode: Mode<any> };

Given a state object, returns a {state, mode} object with the inner mode and its state for the current position.

function isWordChar

isWordChar: (ch: string) => boolean;

Check if a char is part of an alphabet.

function multiplexingMode

multiplexingMode: (
    outer: Mode<any>,
    ...others: MultiplexedInnerMode[]
) => Mode<any>;

Mode combinator that can be used to easily 'multiplex' between several modes. When given as first argument a mode object, and as other arguments any number of {open, close, mode [, delimStyle, innerStyle, parseDelimiters]} objects, it will return a mode object that starts parsing using the mode passed as first argument, but will switch to another mode as soon as it encounters a string that occurs in one of the open fields of the passed objects. When in a sub-mode, it will go back to the top mode again when the close string is encountered. Pass "\n" for open or close if you want to switch on a blank line.
When delimStyle is specified, it will be the token style returned for the delimiter tokens (as well as [delimStyle]-open on the opening token and [delimStyle]-close on the closing token). When innerStyle is specified, it will be the token style added for each inner mode token. When parseDelimiters is true, the content of the delimiters will also be passed to the inner mode. (And delimStyle is ignored.)
The outer mode will not see the content between the delimiters.

function normalizeKeyMap

normalizeKeyMap: (km: KeyMap) => KeyMap;

Modify a keymap to normalize modifier order and properly recognize multi-stroke bindings.

function off

off: {
    <T extends keyof DocEventMap>(
        doc: Doc,
        eventName: T,
        handler: DocEventMap[T]
    ): void;
    <T extends keyof EditorEventMap>(
        cm: Editor,
        eventName: T,
        handler: EditorEventMap[T]
    ): void;
    <T extends keyof LineHandleEventMap>(
        lineHandle: LineHandle,
        eventName: T,
        handler: LineHandleEventMap[T]
    ): void;
    <T extends keyof TextMarkerEventMap>(
        textMarker: TextMarker<unknown>,
        eventName: T,
        handler: TextMarkerEventMap[T]
    ): void;
    <T extends 'redraw'>(
        lineWidget: LineWidget,
        eventName: T,
        handler: LineWidgetEventMap[T]
    ): void;
    (element: any, eventName: string, handler: () => void): void;
    <T extends keyof CompletionEventMap>(
        hints: Hints,
        eventName: T,
        handler: CompletionEventMap[T]
    ): void;
};

function on

on: {
    <T extends keyof DocEventMap>(
        doc: Doc,
        eventName: T,
        handler: DocEventMap[T]
    ): void;
    <T extends keyof EditorEventMap>(
        cm: Editor,
        eventName: T,
        handler: EditorEventMap[T]
    ): void;
    <T extends keyof LineHandleEventMap>(
        lineHandle: LineHandle,
        eventName: T,
        handler: LineHandleEventMap[T]
    ): void;
    <T extends keyof TextMarkerEventMap>(
        textMarker: TextMarker<unknown>,
        eventName: T,
        handler: TextMarkerEventMap[T]
    ): void;
    <T extends 'redraw'>(
        LineWidget: LineWidget,
        eventName: T,
        handler: LineWidgetEventMap[T]
    ): void;
    (element: any, eventName: string, handler: () => void): void;
    <T extends keyof CompletionEventMap>(
        hints: Hints,
        eventName: T,
        handler: CompletionEventMap[T]
    ): void;
};

function overlayMode

overlayMode: {
    (base: Mode<any>, overlay: Mode<any>, combine?: boolean): Mode<any>;
    (base: Mode<any>, overlay: Mode<any>, combine?: boolean): Mode<any>;
};

Utility function from the overlay.js addon that allows modes to be combined. The mode given as the base argument takes care of most of the normal mode functionality, but a second (typically simple) mode is used, which can override the style of text. Both modes get to parse all of the text, but when both assign a non-null style to a piece of code, the overlay wins, unless the combine argument was true and not overridden, or state.overlay.combineTokens was true, in which case the styles are combined.

function registerHelper

registerHelper: (namespace: string, name: string, helper: any) => void;

Registers a helper value with the given name in the given namespace (type). This is used to define functionality that may be looked up by mode. Will create (if it doesn't already exist) a property on the CodeMirror object for the given type, pointing to an object that maps names to values. I.e. after doing CodeMirror.registerHelper("hint", "foo", myFoo), the value CodeMirror.hint.foo will point to myFoo.

function requireMode

requireMode: (
    mode: string | { name: string },
    callback: () => void,
    options?: RequireModeOptions
) => void;

function runMode

runMode: (
    text: string,
    mode: string | ModeSpec<unknown>,
    callback:
        | HTMLElement
        | ((
              text: string,
              style?: string | null,
              row?: number,
              column?: number,
              state?: any
          ) => void),
    options?: { tabSize?: number | undefined; state?: any }
) => void;

Runs a CodeMirror mode over text without opening an editor instance.
Parameter text
The document to run through the highlighter.
Parameter mode
The mode to use (must be loaded as normal).
Parameter callback
If this is a function, it will be called for each token with five arguments, the token's text, the token's style class (may be null for unstyled tokens), the number of row of the token, the column position of token and the state of mode. If it is a DOM node, the tokens will be converted to span elements as in an editor, and inserted into the node (through innerHTML).

function scanForClosingTag

scanForClosingTag: (
    cm: Editor,
    pos: Position,
    name: string,
    end?: Position
) => XmlTag | null | undefined;

function showHint

showHint: (cm: Editor, hinter?: HintFunction, options?: ShowHintOptions) => void;

Provides a framework for showing autocompletion hints. Defines editor.showHint, which takes an optional options object, and pops up a widget that allows the user to select a completion. Finding hints is done with a hinting functions (the hint option), which is a function that take an editor instance and options object, and return a {list, from, to} object, where list is an array of strings or objects (the completions), and from and to give the start and end of the token that is being completed as {line, ch} objects. An optional selectedHint property (an integer) can be added to the completion object to control the initially selected hint.

function signal

signal: {
    <T extends keyof DocEventMap>(
        doc: Doc,
        eventName: T,
        ...args: Parameters<DocEventMap[T]>
    ): void;
    <T extends keyof EditorEventMap>(
        cm: Editor,
        eventName: T,
        ...args: Parameters<EditorEventMap[T]>
    ): void;
    <T extends keyof LineHandleEventMap>(
        lineHandle: LineHandle,
        eventName: T,
        ...args: Parameters<LineHandleEventMap[T]>
    ): void;
    <T extends keyof TextMarkerEventMap>(
        textMarker: TextMarker<unknown>,
        eventName: T,
        ...args: Parameters<TextMarkerEventMap[T]>
    ): void;
    <T extends 'redraw'>(
        lineWidget: LineWidget,
        eventName: T,
        ...args: Parameters<LineWidgetEventMap[T]>
    ): void;
    (target: any, name: string, ...args: any[]): void;
    <T extends keyof CompletionEventMap>(
        hints: Hints,
        eventName: T,
        ...args: Parameters<CompletionEventMap[T]>
    ): void;
};

Various CodeMirror-related objects emit events, which allow client code to react to various situations. Handlers for such events can be registered with the on and off methods on the objects that the event fires on. To fire your own events, use CodeMirror.signal(target, name, args...), where target is a non-DOM-node object.

Current position in the string.

property start

start: number;

Where the stream's position was when it was first passed to the token function.

property string

string: string;

The current line's content.

property tabSize

tabSize: number;

Number of spaces per tab character.

method backUp

backUp: (n: number) => void;

Backs up the stream n characters. Backing it up further than the start of the current token will cause things to break, so be careful.

method column

column: () => number;

Returns the column (taking into account tabs) at which the current token starts.

method current

current: () => string;

Get the string between the start of the current token and the current stream position.

method eat

eat: (match: string | RegExp | ((char: string) => boolean)) => string;

match can be a character, a regular expression, or a function that takes a character and returns a boolean. If the next character in the stream 'matches' the given argument, it is consumed and returned. Otherwise, undefined is returned.

method eatSpace

eatSpace: () => boolean;

Shortcut for eatWhile when matching white-space.

method eatWhile

eatWhile: (match: string | RegExp | ((char: string) => boolean)) => boolean;

Repeatedly calls eat with the given argument, until it fails. Returns true if any characters were eaten.

method eol

eol: () => boolean;

Returns true only if the stream is at the end of the line.

method indentation

method match

match: {
    (pattern: string, consume?: boolean, caseFold?: boolean): boolean;
    (pattern: RegExp, consume?: boolean): string[];
};

Act like a multi-character eat - if consume is true or not given - or a look-ahead that doesn't update the stream position - if it is false. pattern can be either a string or a regular expression starting with ^. When it is a string, caseFold can be set to true to make the match case-insensitive. When successfully matching a regular expression, the returned value will be the array returned by match, in case you need to extract matched groups.

method next

next: () => string | null;

Returns the next character in the stream and advances it. Also returns null when no more characters are available.

method peek

peek: () => string | null;

Returns the next character in the stream without advancing it. Will return an null at the end of the line.

method skipTo

skipTo: (ch: string) => boolean;

Skips to the next occurrence of the given character, if found on the current line (doesn't advance the stream if the character does not occur on the line).
Returns true if the character was found.

method skipToEnd

skipToEnd: () => void;

Moves the position to the end of the line.

method sol

sol: () => boolean;

Returns true only if the stream is at the start of the line.

Given a line handle, returns the current position of that line (or null when it is no longer in the document).

method getMode

getMode: () => Mode<unknown>;

Gets the mode object for the editor. Note that this is distinct from getOption("mode"), which gives you the mode specification, rather than the resolved, instantiated mode object.

method getRange

getRange: (from: Position, to: Position, seperator?: string) => string;

Returns whether the document is currently clean — not modified since initialization or the last call to markClean if no argument is passed, or since the matching call to changeGeneration if a generation value is given.

method iterLinkedDocs

iterLinkedDocs: (fn: (doc: Doc, sharedHist: boolean) => void) => void;

Will call the given function for all documents linked to the target document. It will be passed two arguments, the linked document and a boolean indicating whether that document shares history with the target.

method replaceSelections

replaceSelections: (replacements: string[], collapse?: string) => void;

Replaces the content of the selections with the strings in the array. The length of the given array should be the same as the number of active selections. The collapse argument works the same as in replaceSelection.

        handleMouseEvents?: boolean | undefined;
    }
) => TextMarker<Position>;

Inserts a bookmark, a handle that follows the text around it as it is being edited, at the given position. A bookmark has two methods find() and clear(). The first returns the current position of the bookmark, if it is still in the document, and the second explicitly removes the bookmark.

method setExtending

setExtending: (value: boolean) => void;

Sets or clears the 'extending' flag , which acts similar to the shift key, in that it will cause cursor movement and calls to extendSelection to leave the selection anchor in place.

method setHistory

setHistory: (history: any) => void;

Replace the editor's undo history with the one provided, which must be a value as returned by getHistory. Note that this will have entirely undefined results if the editor content isn't also the same as it was when getHistory was called.

setLine: (n: number, text: string) => void;

Set the content of line n.

method setSelection

setSelection: (
    anchor: Position,

    ranges: Array<{ anchor: Position; head: Position }>,
    primary?: number,
    options?: SelectionOptions
) => void;

Sets a new set of selections. There must be at least one selection in the given array. When primary is a number, it determines which selection is the primary one.

It can be a `{line, ch} object, or can be left off to default to the start of the document caseFold: This is only relevant when matching a string. IT will cause the search to be case-insenstive

interface Editor

interface Editor extends DocOrEditor {}

Methods prefixed with doc. can, unless otherwise specified, be called both on CodeMirror (editor) instances and CodeMirror.Doc instances. Thus, the Editor interface extends DocOrEditor defining the common API.

state: any;

Expose the state object, so that the Editor.state.completionActive property is reachable

method addKeyMap

addKeyMap: (map: string | KeyMap, bottom?: boolean) => void;

Attach an additional keymap to the editor. This is mostly useful for add - ons that need to register some key handlers without trampling on the extraKeys option. Maps added in this way have a higher precedence than the extraKeys and keyMap options, and between them, the maps added earlier have a lower precedence than those added later, unless the bottom argument was passed, in which case they end up below other keymaps added with this method.

method addLineClass

addLineClass: (line: any, where: string, _class_: string) => LineHandle;

Set a CSS class name for the given line.line can be a number or a line handle. where determines to which element this class should be applied, can can be one of "text" (the text element, which lies in front of the selection), "background"(a background element that will be behind the selection), or "wrap" (the wrapper node that wraps all of the line's elements, including gutter elements). class should be the name of the class to apply.

    node: HTMLElement,
    options?: LineWidgetOptions
) => LineWidget;

Adds a line widget, an element shown below a line, spanning the whole of the editor's width, and moving the lines below it downwards. line should be either an integer or a line handle, and node should be a DOM node, which will be displayed below the given line. options, when given, should be an object that configures the behavior of the widget. Note that the widget node will become a descendant of nodes with CodeMirror-specific CSS classes, and those classes might in some cases affect it.

addOverlay: (
    mode: any,
    options?: { opaque?: boolean | undefined; priority?: number | undefined }
) => void;

Enable a highlighting overlay.This is a stateless mini-mode that can be used to add extra highlighting. For example, the search add - on uses it to highlight the term that's currently being searched. mode can be a mode spec or a mode object (an object with a token method). The options parameter is optional. If given, it should be an object. Currently, only the opaque option is recognized. This defaults to off, but can be given to allow the overlay styling, when not null, to override the styling of the base mode entirely, instead of the two being applied together.

method addWidget

addWidget: (pos: Position, node: HTMLElement, scrollIntoView: boolean) => void;

Puts node, which should be an absolutely positioned DOM node, into the editor, positioned right below the given { line , ch } position. When scrollIntoView is true, the editor will ensure that the entire node is visible (if possible). To remove the widget again, simply use DOM methods (move it somewhere else, or call removeChild on its parent).

method charCoords

charCoords: (
    pos: Position,
    mode?: CoordsMode
) => { left: number; right: number; top: number; bottom: number };

If it is "page" or not given, they are relative to the top-left corner of the page. This differs from cursorCoords in that it'll give the size of the whole character, rather than just the position that the cursor would have when it would sit at that position.

method clearGutter

clearGutter: (gutterID: string) => void;

Remove all gutter markers in the gutter with the given ID.

method coordsChar

coordsChar: (
    object: { left: number; top: number },
    mode?: CoordsMode
) => Position;

Given an { left , top } object , returns the { line , ch } position that corresponds to it. The optional mode parameter determines relative to what the coordinates are interpreted. It may be "window", "page" (the default), or "local".

method cursorCoords

cursorCoords: (
    where?: boolean | Position | null,
    mode?: CoordsMode
) => { left: number; top: number; bottom: number };

Returns an { left , top , bottom } object containing the coordinates of the cursor position. If mode is "local", they will be relative to the top-left corner of the editable document. If it is "page" or not given, they are relative to the top-left corner of the page. where specifies the position at which you want to measure. A boolean indicates either the start(true) or the end(false) of the selection.

method defaultCharWidth

defaultCharWidth: () => number;

Returns the pixel width of an 'x' in the default font for the editor. (Note that for non-monospace fonts, this is mostly useless, and even for monospace fonts, non-ascii characters might have a different width).

) => { line: number; ch: number; hitSide?: boolean | undefined };

Used to find the target position for horizontal cursor motion.start is a { line , ch } object, an integer(may be negative), and unit one of the string "char", "column", or "word". Will return a position that is produced by moving amount times the distance specified by unit. When visually is true , motion in right - to - left text will be visual rather than logical. When the motion was clipped by hitting the end or start of the document, the returned value will have a hitSide property set to true.

method findPosV

findPosV: (
    start: Position,
    amount: number,
    unit: string
) => { line: number; ch: number; hitSide?: boolean | undefined };

Similar to findPosH , but used for vertical motion.unit may be "line" or "page". The other arguments and the returned value have the same interpretation as they have in findPosH.

    option: K
) => EditorConfiguration[K];

Retrieves the current value of the given option for this editor instance.

method getScrollerElement

method getStateAfter

getStateAfter: (line?: number) => any;

Returns the mode's parser state, if any, at the end of the given line number. If no line number is given, the state at the end of the document is returned. This can be useful for storing parsing errors in the state, or getting other kinds of contextual information for a line.

method getTokenAt

getTokenAt: (pos: Position, precise?: boolean) => Token;

Retrieves information about the token the current mode found before the given position (a {line, ch} object).

method getTokenTypeAt

getTokenTypeAt: (pos: Position) => string;

This is a (much) cheaper version of getTokenAt useful for when you just need the type of the token at a given position, and no other information. Will return null for unstyled tokens, and a string, potentially containing multiple space-separated style names, otherwise.

method getValue

getValue: (seperator?: string) => string;

Get the content of the current editor document. You can pass it an optional argument to specify the string to be used to separate lines (defaults to "\n").

method getViewport

getViewport: () => { from: number; to: number };

Returns a { from , to } object indicating the start (inclusive) and end (exclusive) of the currently rendered part of the document. In big documents, when most content is scrolled out of view, CodeMirror will only render the visible part, and a margin around it. See also the viewportChange event.

Returns the DOM node that represents the editor, and controls its size. Remove this from your tree to delete an editor instance.

method hasFocus

hasFocus: () => boolean;

method heightAtLine

heightAtLine: (line: any, mode?: CoordsMode, includeWidgets?: boolean) => number;

Computes the height of the top of a line, in the coordinate system specified by mode, it may be "window", "page" (the default), or "local". When a line below the bottom of the document is specified, the returned value is the bottom of the last line in the document. By default, the position of the actual text is returned. If includeWidgets is true and the line has line widgets, the position above the first line widget is returned.

method indentLine

indentLine: (line: number, dir?: string) => void;

Adjust the indentation of the given line. The second argument (which defaults to "smart") may be one of: "prev" Base indentation on the indentation of the previous line. "smart" Use the mode's smart indentation if available, behave like "prev" otherwise. "add" Increase the indentation of the line by one indent unit. "subtract" Reduce the indentation of the line.

    ): void;
};

method operation

operation: <T>(fn: () => T) => T;

CodeMirror internally buffers changes and only updates its DOM structure after it has finished performing some operation. If you need to perform a lot of operations on a CodeMirror instance, you can call this method with a function argument. It will call the function, buffering up all changes, and only doing the expensive update after the function returns. This can be a lot faster. The return value from this method will be the return value of your function.

method phrase

phrase: (text: string) => unknown;

Allow the given string to be translated with the phrases option.

method refresh

refresh: () => void;

If your code does something to change the size of the editor element (window resizes are already listened for), or unhides it, you should probably follow up by calling this method to ensure CodeMirror is still looking as intended.

method removeKeyMap

removeKeyMap: (map: string | KeyMap) => void;

Disable a keymap added with addKeyMap.Either pass in the keymap object itself , or a string, which will be compared against the name property of the active keymaps.

method removeLineClass

removeLineClass: (line: any, where: string, class_?: string) => LineHandle;

Remove a CSS class from a line.line can be a line handle or number. where should be one of "text", "background", or "wrap"(see addLineClass). class can be left off to remove all classes for the specified node, or be a string to remove only a specific class.

method removeOverlay

removeOverlay: (mode: any) => void;

Pass this the exact argument passed for the mode parameter to addOverlay to remove an overlay again.

method scrollIntoView

scrollIntoView: (

        | { left: number; top: number; right: number; bottom: number }
        | { from: Position; to: Position },
    margin?: number
) => void;

Scrolls the given element into view. pos can be: - a { line , ch } position, referring to a given character - null, to refer to the cursor - a { left , top , right , bottom } object, in editor-local coordinates - a { from, to } object, in editor-local coordinates The margin parameter is optional. When given, it indicates the amount of pixels around the given area that should be made visible as well.

method scrollTo

scrollTo: (x?: number | null, y?: number | null) => void;

Scroll the editor to a given(pixel) position.Both arguments may be left as null or undefined to have no effect.

method setCursor

setCursor: (
    pos: Position | number,
    ch?: number,
    options?: {
        bias?: number | undefined;
        origin?: string | undefined;
        scroll?: boolean | undefined;
    }
) => void;

Set the cursor position. You can either pass a single {line, ch} object, or the line and the character as two separate parameters. Will replace all selections with a single, empty selection at the given position. The supported options are the same as for setSelection

method setGutterMarker

setGutterMarker: (
    line: any,
    gutterID: string,
    value: HTMLElement | null
) => LineHandle;

Sets the gutter marker for the given gutter (identified by its CSS class, see the gutters option) to the given value. Value can be either null, to clear the marker, or a DOM element, to set it. The DOM element will be shown in the specified gutter next to the specified line.

method setOption

setOption: <K extends keyof EditorConfiguration>(
    option: K,
    value: EditorConfiguration[K]
) => void;

Change the configuration of the editor. option should the name of an option, and value should be a valid value for that option.

method setSize

setSize: (width: any, height: any) => void;

Programatically set the size of the editor (overriding the applicable CSS rules). width and height height can be either numbers(interpreted as pixels) or CSS units ("100%", for example). You can pass null for either of them to indicate that that dimension should not be changed.

method setValue

setValue: (content: string) => void;

Set the content of the current editor document.

method startOperation

startOperation: () => void;

In normal circumstances, use the above operation method. But if you want to buffer operations happening asynchronously, or that can't all be wrapped in a callback function, you can call startOperation to tell CodeMirror to start buffering changes, and endOperation to actually render all the updates. Be careful: if you use this API and forget to call endOperation, the editor will just never update.

method swapDoc

swapDoc: (doc: Doc) => Doc;

Attach a new document to the editor. Returns the old document, which is now no longer associated with an editor.

method toggleOverwrite

toggleOverwrite: (value?: boolean) => void;

property foldCode

foldCode: (
    lineOrPos: number | Position,
    rangeFindeOrFoldOptions?: FoldRangeFinder | FoldOptions,
    force?: 'fold' | 'unfold'
) => void;

Helps with code folding. Adds a foldCode method to editor instances, which will try to do a code fold starting at the given line, or unfold the fold that is already present. The method takes as first argument the position that should be folded (may be a line number or a Pos), and as second optional argument either a range-finder function, or an options object.

method foldOption

interface EditorChangeCancellable

interface EditorChangeCancellable extends EditorChange {}

method cancel

cancel: () => void;

method update

update: (from?: Position, to?: Position, text?: string[]) => void;

may be used to modify the change. All three arguments to update are optional, and can be left off to leave the existing value for that field intact. If the change came from undo/redo, update is undefined and the change cannot be modified.

interface EditorConfiguration

interface EditorConfiguration {}

property addModeClass

addModeClass?: boolean | undefined;

When enabled (off by default), an extra CSS class will be added to each token, indicating the (inner) mode that produced it, prefixed with "cm-m-". For example, tokens from the XML mode will get the cm-m-xml class.

property allowDropFileTypes

allowDropFileTypes?: string[] | null | undefined;

When set (default is null) only files whose type is in the array can be dropped into the editor. The strings should be MIME types, and will be checked against the type of the File object as reported by the browser.

property autocapitalize

autocapitalize?: boolean | undefined;

Specifies whether or not autocapitalization will be enabled on the input.

property autocorrect

autocorrect?: boolean | undefined;

Specifies whether or not autocorrect will be enabled on the input.

property autofocus

autofocus?: boolean | undefined;

Can be used to make CodeMirror focus itself on initialization. Defaults to off. When fromTextArea is used, and no explicit value is given for this option, it will be set to true when either the source textarea is focused, or it has an autofocus attribute and no other element is focused.

property configureMouse

configureMouse?:
    | ((
          cm: Editor,
          repeat: 'single' | 'double' | 'triple',
          event: Event
      ) => MouseSelectionConfiguration)
    | undefined;

Allows you to configure the behavior of mouse selection and dragging. The function is called when the left mouse button is pressed.

property coverGutterNextToScrollbar

coverGutterNextToScrollbar?: boolean | undefined;

When fixedGutter is on, and there is a horizontal scrollbar, by default the gutter will be visible to the left of this scrollbar. If this option is set to true, it will be covered by an element with class CodeMirror-gutter-filler.

property cursorBlinkRate

cursorBlinkRate?: number | undefined;

Half - period in milliseconds used for cursor blinking. The default blink rate is 530ms.

property cursorHeight

cursorHeight?: number | undefined;

Determines the height of the cursor. Default is 1 , meaning it spans the whole height of the line. For some fonts (and by some tastes) a smaller height (for example 0.85), which causes the cursor to not reach all the way to the bottom of the line, looks better

property cursorScrollMargin

cursorScrollMargin?: number | undefined;

How much extra space to always keep above and below the cursor when approaching the top or bottom of the visible view in a scrollable document. Default is 0.

property direction

direction?: 'ltr' | 'rtl' | undefined;

Flips overall layout and selects base paragraph direction to be left-to-right or right-to-left. Default is "ltr". CodeMirror applies the Unicode Bidirectional Algorithm to each line, but does not autodetect base direction — it's set to the editor direction for all lines. The resulting order is sometimes wrong when base direction doesn't match user intent (for example, leading and trailing punctuation jumps to the wrong side of the line). Therefore, it's helpful for multilingual input to let users toggle this option.

property dragDrop

dragDrop?: boolean | undefined;

Controls whether drag-and - drop is enabled. On by default.

property electricChars

electricChars?: boolean | undefined;

Configures whether the editor should re-indent the current line when a character is typed that might change its proper indentation (only works if the mode supports indentation). Default is true.

property extraKeys

extraKeys?: string | KeyMap | undefined;

Can be used to specify extra keybindings for the editor, alongside the ones defined by keyMap. Should be either null, or a valid keymap value.

property firstLineNumber

firstLineNumber?: number | undefined;

At which number to start counting lines. Default is 1.

property fixedGutter

fixedGutter?: boolean | undefined;

Determines whether the gutter scrolls along with the content horizontally (false) or whether it stays fixed during horizontal scrolling (true, the default).

property flattenSpans

flattenSpans?: boolean | undefined;

By default, CodeMirror will combine adjacent tokens into a single span if they have the same class. This will result in a simpler DOM tree, and thus perform better. With some kinds of styling(such as rounded corners), this will change the way the document looks. You can set this option to false to disable this behavior.

property gutters

gutters?:
    | Array<string | { className: string; style?: string | undefined }>
    | undefined;

Can be used to add extra gutters (beyond or instead of the line number gutter). Should be an array of CSS class names, each of which defines a width (and optionally a background), and which will be used to draw the background of the gutters. May include the CodeMirror-linenumbers class, in order to explicitly set the position of the line number gutter (it will default to be to the right of all other gutters). These class names are the keys passed to setGutterMarker.

property historyEventDelay

historyEventDelay?: number | undefined;

The period of inactivity (in milliseconds) that will cause a new history event to be started when typing or deleting. Defaults to 500.

property indentUnit

indentUnit?: number | undefined;

How many spaces a block (whatever that means in the edited language) should be indented. The default is 2.

property indentWithTabs

indentWithTabs?: boolean | undefined;

Whether, when indenting, the first N*tabSize spaces should be replaced by N tabs. Default is false.

property inputStyle

inputStyle?: InputStyle | undefined;

Selects the way CodeMirror handles input and focus. The core library defines the "textarea" and "contenteditable" input models. On mobile browsers, the default is "contenteditable". On desktop browsers, the default is "textarea". Support for IME and screen readers is better in the "contenteditable" model.

property keyMap

keyMap?: string | undefined;

Configures the keymap to use. The default is "default", which is the only keymap defined in codemirror.js itself. Extra keymaps are found in the keymap directory. See the section on keymaps for more information.

property lineNumberFormatter

lineNumberFormatter?: ((line: number) => string) | undefined;

A function used to format line numbers. The function is passed the line number, and should return a string that will be shown in the gutter.

property lineNumbers

lineNumbers?: boolean | undefined;

Whether to show line numbers to the left of the editor.

property lineSeparator

lineSeparator?: string | null | undefined;

Explicitly set the line separator for the editor. By default (value null), the document will be split on CRLFs as well as lone CRs and LFs, and a single LF will be used as line separator in all output (such as getValue). When a specific string is given, lines will only be split on that string, and output will, by default, use that same separator.

property lineWiseCopyCut

lineWiseCopyCut?: boolean | undefined;

When enabled, which is the default, doing copy or cut when there is no selection will copy or cut the whole lines that have cursors on them.

property lineWrapping

lineWrapping?: boolean | undefined;

Whether CodeMirror should scroll or wrap for long lines. Defaults to false (scroll).

property maxHighlightLength

maxHighlightLength?: number | undefined;

When highlighting long lines, in order to stay responsive, the editor will give up and simply style the rest of the line as plain text when it reaches a certain position. The default is 10000. You can set this to Infinity to turn off this behavior.

property mode

mode?: string | ModeSpec<ModeSpecOptions> | undefined;

string|object. The mode to use. When not given, this will default to the first mode that was loaded. It may be a string, which either simply names the mode or is a MIME type associated with the mode. Alternatively, it may be an object containing configuration options for the mode, with a name property that names the mode (for example {name: "javascript", json: true}).

property onDragEvent

onDragEvent?: ((instance: Editor, event: DragEvent) => boolean) | undefined;

When given , this will be called when the editor is handling a dragenter , dragover , or drop event. It will be passed the editor instance and the event object as arguments. The callback can choose to handle the event itself , in which case it should return true to indicate that CodeMirror should not do anything further.

property onKeyEvent

onKeyEvent?: ((instance: Editor, event: KeyboardEvent) => boolean) | undefined;

This provides a rather low-level hook into CodeMirror's key handling. If provided, this function will be called on every keydown, keyup, and keypress event that CodeMirror captures. It will be passed two arguments, the editor instance and the key event. This key event is pretty much the raw key event, except that a stop() method is always added to it. You could feed it to, for example, jQuery.Event to further normalize it. This function can inspect the key event, and handle it if it wants to. It may return true to tell CodeMirror to ignore the event. Be wary that, on some browsers, stopping a keydown does not stop the keypress from firing, whereas on others it does. If you respond to an event, you should probably inspect its type property and only do something when it is keydown (or keypress for actions that need character data).

property pasteLinesPerSelection

pasteLinesPerSelection?: boolean | undefined;

When pasting something from an external source (not from the editor itself), if the number of lines matches the number of selection, CodeMirror will by default insert one line per selection. You can set this to false to disable that behavior.

property phrases

phrases?: { [s: string]: unknown } | undefined;

Some addons run user-visible strings (such as labels in the interface) through the phrase method to allow for translation. This option determines the return value of that method. When it is null or an object that doesn't have a property named by the input string, that string is returned. Otherwise, the value of the property corresponding to that string is returned.

property pollInterval

pollInterval?: number | undefined;

Indicates how quickly CodeMirror should poll its input textarea for changes(when focused). Most input is captured by events, but some things, like IME input on some browsers, don't generate events that allow CodeMirror to properly detect it. Thus, it polls. Default is 100 milliseconds.

property readOnly

readOnly?: boolean | 'nocursor' | undefined;

boolean|string. This disables editing of the editor content by the user. If the special value "nocursor" is given (instead of simply true), focusing of the editor is also disallowed.

property resetSelectionOnContextMenu

resetSelectionOnContextMenu?: boolean | undefined;

Controls whether, when the context menu is opened with a click outside of the current selection, the cursor is moved to the point of the click. Defaults to true.

property rtlMoveVisually

rtlMoveVisually?: boolean | undefined;

Determines whether horizontal cursor movement through right-to-left (Arabic, Hebrew) text is visual (pressing the left arrow moves the cursor left) or logical (pressing the left arrow moves to the next lower index in the string, which is visually right in right-to-left text). The default is false on Windows, and true on other platforms.

property screenReaderLabel

screenReaderLabel?: string | undefined;

This label is read by the screenreaders when CodeMirror text area is focused. This is helpful for accessibility.

property scrollbarStyle

scrollbarStyle?: keyof ScrollbarModels | undefined;

Chooses a scrollbar implementation. The default is "native", showing native scrollbars. The core library also provides the "null" style, which completely hides the scrollbars. Addons can implement additional scrollbar models.

property selectionsMayTouch

selectionsMayTouch?: boolean | undefined;

Determines whether multiple selections are joined as soon as they touch (the default) or only when they overlap (true).

property showCursorWhenSelecting

showCursorWhenSelecting?: boolean | undefined;

Whether the cursor should be drawn when a selection is active. Defaults to false.

property smartIndent

smartIndent?: boolean | undefined;

Whether to use the context-sensitive indentation that the mode provides (or just indent the same as the line before). Defaults to true.

property specialCharPlaceholder

specialCharPlaceholder?: ((char: string) => HTMLElement) | undefined;

A function that, given a special character identified by the specialChars option, produces a DOM node that is used to represent the character. By default, a red dot (•) is shown, with a title tooltip to indicate the character code.

property specialChars

specialChars?: RegExp | undefined;

A regular expression used to determine which characters should be replaced by a special placeholder. Mostly useful for non-printing special characters. The default is /[\u0000-\u001f\u007f-\u009f\u00ad\u061c\u200b-\u200f\u2028\u2029\ufeff\ufff9-\ufffc]/.

property spellcheck

spellcheck?: boolean | undefined;

Specifies whether or not spellcheck will be enabled on the input.

property tabindex

property tabSize

tabSize?: number | undefined;

The width of a tab character. Defaults to 4.

property theme

theme?: string | undefined;

The theme to style the editor with. You must make sure the CSS file defining the corresponding .cm-s-[name] styles is loaded. The default is "default".

property undoDepth

undoDepth?: number | undefined;

The maximum number of undo levels that the editor stores. Defaults to 40.

property value

value?: string | Doc | undefined;

The starting value of the editor. Can be a string, or a document object.

property viewportMargin

viewportMargin?: number | undefined;

Specifies the amount of lines that are rendered above and below the part of the document that's currently scrolled into view. This affects the amount of updates needed when scrolling, and the amount of work that such an update does. You should usually leave it at its default, 10. Can be set to Infinity to make sure the whole document is always rendered, and thus the browser's text search works on it. This will have bad effects on performance of big documents.

property workDelay

workDelay?: number | undefined;

See workTime.

property workTime

workTime?: number | undefined;

Highlighting is done by a pseudo background thread that will work for workTime milliseconds, and then use timeout to sleep for workDelay milliseconds. The defaults are 200 and 300, you can change these options to make the highlighting more or less aggressive.

interface EditorConfiguration

interface EditorConfiguration {}

property continueComments

continueComments?:
    | boolean
    | string
    | { key: string; continueLineComment?: boolean | undefined }

Controls whether single-line selections, or just cursor selections, are styled. Defaults to false (only cursor selections).

interface TernOptions

interface TernOptions {}

property defs

defs?: Tern.Def[] | undefined;

An array of JSON definition data structures.

property plugins

plugins?: Tern.ConstructorOptions['plugins'] | undefined;

An object mapping plugin names to configuration options.

property useWorker

useWorker?: boolean | undefined;

Set to true to enable web worker mode. You'll probably want to feature detect the actual value you use here, for example !!window.Worker.

property workerDeps

workerDeps?: string[] | undefined;

An array of paths pointing (relative to workerScript) to the Acorn and Tern libraries and any Tern plugins you want to load. Or, if you minified those into a single script and included them in the workerScript, simply leave this undefined.

property workerScript

workerScript?: string | undefined;

The main script of the worker. Point this to wherever you are hosting worker.js from this directory.

method completionTip

completionTip: (
    data: Tern.CompletionsQueryResult
) => string | HTMLElement | null;

Customize the content in tooltips for completions. Is passed a single argument — the completion's data as returned by Tern — and may return a string, DOM node, or null to indicate that no tip should be shown. By default the docstring is shown.

method fileFilter

fileFilter: (value: string, docName: string, doc: Doc) => string;

This function will be applied to documents before passing them on to Tern.

method getFile

getFile: (name: string, callback: (docValue: string | null) => any) => any;

Can be used to access files in the project that haven't been loaded yet. Simply do callback(null) to indicate that a file is not available.

method responseFilter

responseFilter: <Q extends Tern.Query>(
    doc: Doc,
    query: Q,
    request: Tern.Document,
    error: Error | undefined,
    data: Tern.QueryResult<Q> | undefined
) => Tern.QueryResult<Q> | undefined;

This function will be applied to the Tern responses before treating them

method showError

showError: (editor: Editor, message: Error | string) => void;

Can be used to override the way errors are displayed.

method switchToDoc

switchToDoc: (name: string, doc: Doc) => void;

This function should, when providing a multi-file view, switch the view or focus to the named file.

method typeTip

typeTip: (data: Tern.TypeQueryResult) => string | HTMLElement | null;

Like completionTip, but for the tooltips shown for type queries.

interface TextMarker

interface TextMarker<T = MarkerRange | Position>
    extends Partial<TextMarkerOptions> {}

method changed

changed: () => void;

Called when you've done something that might change the size of the marker and want to cheaply update the display

method clear

clear: () => void;

Remove the mark.

method find

find: () => T | undefined;

Returns a {from, to} object (both holding document positions), indicating the current position of the marked range, or undefined if the marker is no longer in the document.

method off

off: <T extends keyof TextMarkerEventMap>(
    eventName: T,
    handler: TextMarkerEventMap[T]
) => void;

method on

on: <T extends keyof TextMarkerEventMap>(
    eventName: T,
    handler: TextMarkerEventMap[T]
) => void;

interface TextMarkerEventMap

interface TextMarkerEventMap {}

property beforeCursorEnter

beforeCursorEnter: () => void;

property clear

clear: (from: Position, to: Position) => void;

property hide

hide: () => void;

property unhide

unhide: () => void;

interface TextMarkerOptions

interface TextMarkerOptions {}

property addToHistory

addToHistory?: boolean | undefined;

When set to true (default is false), adding this marker will create an event in the undo history that can be individually undone (clearing the marker).

property atomic

atomic?: boolean | undefined;

Atomic ranges act as a single unit when cursor movement is concerned — i.e. it is impossible to place the cursor inside of them. You can control whether the cursor is allowed to be placed directly before or after them using selectLeft or selectRight. If selectLeft (or right) is not provided, then inclusiveLeft (or right) will control this behavior.

property attributes

attributes?: { [name: string]: string } | undefined;

When given, add the attributes in the given object to the elements created for the marked text. Adding class or style attributes this way is not supported.

property className

className?: string | undefined;

Assigns a CSS class to the marked stretch of text.

property clearOnEnter

clearOnEnter?: boolean | undefined;

When enabled, will cause the mark to clear itself whenever the cursor enters its range. This is mostly useful for text - replacement widgets that need to 'snap open' when the user tries to edit them. The "clear" event fired on the range handle can be used to be notified when this happens.

property clearWhenEmpty

clearWhenEmpty?: boolean | undefined;

Determines whether the mark is automatically cleared when it becomes empty. Default is true.

property collapsed

collapsed?: boolean | undefined;

Collapsed ranges do not show up in the display. Setting a range to be collapsed will automatically make it atomic.

property css

css?: string | undefined;

A string of CSS to be applied to the covered text. For example "color: #fe3".

property endStyle

endStyle?: string | undefined;

Equivalent to startStyle, but for the rightmost span.

property handleMouseEvents

handleMouseEvents?: boolean | undefined;

When replacedWith is given, this determines whether the editor will capture mouse and drag events occurring in this widget. Default is false—the events will be left alone for the default browser handler, or specific handlers on the widget, to capture.

property inclusiveLeft

inclusiveLeft?: boolean | undefined;

Determines whether text inserted on the left of the marker will end up inside or outside of it.

property inclusiveRight

inclusiveRight?: boolean | undefined;

Like inclusiveLeft, but for the right side.

property readOnly

readOnly?: boolean | undefined;

A read-only span can, as long as it is not cleared, not be modified except by calling setValue to reset the whole document. Note: adding a read-only span currently clears the undo history of the editor, because existing undo events being partially nullified by read - only spans would corrupt the history (in the current implementation).

property replacedWith

replacedWith?: HTMLElement | undefined;

Use a given node to display this range. Implies both collapsed and atomic. The given DOM node must be an inline element (as opposed to a block element).

property selectLeft

selectLeft?: boolean | undefined;

For atomic ranges, determines whether the cursor is allowed to be placed directly to the left of the range. Has no effect on non-atomic ranges.

property selectRight

selectRight?: boolean | undefined;

Like selectLeft, but for the right side.

property shared

shared?: boolean | undefined;

When the target document is linked to other documents, you can set shared to true to make the marker appear in all documents. By default, a marker appears only in its target document.

property startStyle

startStyle?: string | undefined;

Can be used to specify an extra CSS class to be applied to the leftmost span that is part of the marker.

property title

title?: string | undefined;

When given, will give the nodes created for this span a HTML title attribute with the given value.

interface Token

interface Token {}

property end

end: number;

The character at which the token ends.

property start

start: number;

The character(on the given line) at which the token starts.

property state

state: any;

The mode's state at the end of this token.

property string

string: string;

The token's string.

property type

type: string | null;

The token type the mode assigned to the token, such as "keyword" or "comment" (may also be null).
