Registers an autocomplete callback callbackFunction named name with priority priority.

When the Script Editor invokes autocomplete, all registered autocomplete callbacks call in order of ascending priority with the autocomplete request and response. Multiple callbacks may share a priority, but then their calling order is unpredictable. Each callback is intended to return a response table with the same format as the response input table. Callbacks shouldn't yield. The first callback invoked receives the internal autocomplete's response as its response table, and subsequent callbacks receive the previous callback's output as their response table. Callbacks may either modify the passed table or return a new table of the same format.

The callbackFunction must have the following type: (Request: table, Response: table) -> table

The Request table has the following format:

type Request = {
  position: {
    line: number,
    character: number
  },
  textDocument: {
    document: ScriptDocument?,
    script: LuaSourceContainer?
  }
}

• position is the one-indexed cursor position where you are autocompleting.
• textDocument.document is the open ScriptDocument you are completing in, if it exists.
• textDocument.script is the LuaSourceContainer you are completing in, if it exists.

If both textDocument.document and textDocument.script are present, then they correspond to each other: req.textDocument.document:GetScript() == req.textDocument.script

The Response table has the following format:

type Response = {
  items: {
    {
      label: string, -- The label
      kind: Enum.CompletionItemKind?,
      tags: {Enum.CompletionItemTag}?,
      detail: string?,
      documentation: {
        value: string,
      }?,
      overloads: number?,
      learnMoreLink: string?,
      codeSample: string?,
      preselect: boolean?,
      textEdit: {
        newText: string,
        replace: { start: { line: number, character: number }, ["end"]: { line: number, character: number } },
      }?
    }
  }
}

• Response.items is an array of the completion items. The order of this array is insignificant, and it resorts in the editor as the user types.
• Response.items[n].label is the label of the item which display in the autocomplete menu.
• Response.items[n].kind specifies what type of autocomplete item this is. Primarily this controls the icon given to the item in the editor. Not all kinds have a unique icon. If not specified, the editor uses the "Text" icon. Unsupported kinds default to displaying the "Property" icon.
• Response.items[n].tags specifies an array of tags describing this completion item. See the Enum.CompletionItemTag for details on their function.
• Response.items[n].details specifies a string describing details about the completion item. For default items, this is a string representation of their type. Note that, in order for the documentation widget to display, documentation must be present, but documentation.value may be empty.
• Response.items[n].documentation specifies the main body of the documentation in its value field. documentation is present, even if value is empty, so the documentation window displays if either details or overloads are specified.
• Response.items[n].overloads specifies the number of overloads of a function autocompletion.
• Response.items[n].learnMoreLink links to a relevant page on the creator docs. This URL must be a https request to create.roblox.com; no other URLs display in the editor.
• Response.items[n].codeSample specifies a sample use of the completion item. documentation must be non-empty to display this field.
• Response.items[n].preselect If true, the editor sorts this completion item ahead of all others and selects it for the user by default. No effect if false or missing.
• Response.items[n].textEdit If present, accepting the completion applies this text edit - replacing the span between the positions start and end with newText.

If a callback returns a malformed result or encounters an error, the editor discards the modified Response table and uses the built-in autocomplete result list.

Registers a Script Analysis callback callbackFunction named name with priority. When Script Analysis in Studio runs, all registered callbacks call in order of ascending priority. Each callback is intended to return a response table matching the format specified below. Callbacks should not yield.

The request table has the following format, where script is the LuaSourceContainer that is going to be analyzed.

type Request = {
  script: LuaSourceContainer?
}

The response table has the following format, where diagnostics is an array of diagnostic tables. Each diagnostic table has the entries listed below.

type Response = {
  diagnostics: {
    {
      range: {
        start: {
          line: number,
          character: number,
        },
        ["end"]: {
          line: number,
          character: number,
        }
      },
      code: string?,
      message: string,
      severity: Enum.Severity?,
      codeDescription: { href: string }?
    }
  }
}

• range represents a text range that should be highlighted by the linter, providing what line/character to start highlighting and what line/character to stop highlighting.
• code is a label for the message.
• message is a warning message to be displayed for the line. This will also appear on a tooltip when the user hovers their cursor over the line in the Script Editor.
• severity is a Enum.Severity value for the diagnostics. This determines how the diagnostic is categorized in the Script Analysis tool in Studio, as well as how text is highlighted in the Script Editor.
• codeDescription links to a relevant page on the creator docs. This URL must be an https request to create.roblox.com; no other URLs display in the editor.

Requests that a Script Editor open the specified script. Returns (true, nil) if the request succeeds. Returns (false, string) if the request fails, with a string that describes the problem.

If the script is already open, this function succeeds and switches tabs to the associated editor.

end

Returns the edit-time Script.Source for the given script.

This function calls the passed callback using the old contents of the script to calculate the new contents of the script.

If the script is open in the Script Editor, then it issues a request to the editor to update its source. The editor may reject this update if the Script.Source property was out of date with the user's version of the script when this function was called, in which case the callback will be re-invoked and the attempt will be repeated.

The callback may not yield. If the callback returns nil, the operation is cancelled. This function yields until the operation is cancelled or succeeds.

If the script is not open in the editor, the new content updates to the script source, which is the text the editor would display if it is opened.

local ses = game:GetService('ScriptEditorService')
ses:UpdateSourceAsync(Workspace.Script, function(oldContent)
  return oldContent .. " World!"

Fires just before a ScriptDocument object is destroyed, which happens right after the script editor closes. After this event fires, the ScriptDocument enters a "Closed" state, and trying to call its methods throws an error. ScriptDocument objects aren't reusable, even if the script editor reopens the same script.
