# disassemble

> Disassembles a Luau function and returns a formatted bytecode listing string. Argument 1 must be a function; otherwise a type error reports expected function. The closure must be valid and must not be a C closure; invalid closures raise "invalid closure" and C closures raise "cannot disassemble C closure". When an optional second argument is present, the function reads Recursive, ShowLines, ShowConstants, and StringPreviewMax from it. Boolean option fields override the matching defaults, and a numeric StringPreviewMax overrides the default string preview length. Indata structureions are decoded with the bytecode decoder before formatting. The output always has one trailing newline and the function has no registered alias.

<div className="real-function-page">
  ```lua theme={null}
  disassemble(callback: function, options?: DisassembleOptions): string
  ```

  ## Arguments

  <ParamField path={"callback"} type={"function"} required>
    Luau function to disassemble. C closures are rejected.
  </ParamField>

  <ParamField path={"options"} type={"DisassembleOptions"}>
    Optional table read for Recursive, ShowLines, ShowConstants, and StringPreviewMax. Missing fields or fields with the wrong type leave the default value unchanged.
  </ParamField>

  ## Retours

  <ResponseField name={"assembly"} type={"string"}>
    Formatted disassembly text with a trailing newline.
  </ResponseField>

  ## Types

  ### DisassembleOptions

  Contrôle la façon dont le bytecode Luau est rendu dans la sortie du désassemblage.

  | Name               | Type      | Required | Description                                                                                                        |
  | ------------------ | --------- | -------- | ------------------------------------------------------------------------------------------------------------------ |
  | `Recursive`        | `boolean` | No       | Inclut des prototypes enfants imbriqués dans la sortie.                                                            |
  | `ShowLines`        | `boolean` | No       | Affiche les numéros de ligne source à côté des indata structureions lorsque les données de ligne sont disponibles. |
  | `ShowConstants`    | `boolean` | No       | Répertorie la table des constantes pour chaque prototype.                                                          |
  | `StringPreviewMax` | `integer` | No       | Limite le nombre de caractères affichés lors de la prévisualisation des constantes de chaîne.                      |

  ## Exemple

  Disassemble a callback with selected output options.

  ```lua theme={null}
  local assembly = disassemble(function(value)
      return value * 2
  end, {
      Recursive = false,
      ShowLines = true,
      ShowConstants = true,
  })

  print(assembly)
  ```
