Code

gradio.Code(···)

Description

Creates a code editor for viewing code (as an output component), or for entering and editing code (as an input component).

Behavior

As input component: Passes the code entered as a str.

Your function should accept one of these types:
def predict(
	value: str | None
)
	...

As output component: Expects a str of code or a single-element tuple: (filepath,) with the str path to a file containing the code.

Your function should return one of these types:
def predict(···) -> tuple[str] | str | None
	...	
	return value

Initialization

Parameter Description
value

str | Callable | tuple[str] | None

default: None

Default value to show in the code editor. If callable, the function will be called whenever the app loads to set the initial value of the component.
language

Literal[('python', 'markdown', 'json', 'html', 'css', 'javascript', 'typescript', 'yaml', 'dockerfile', 'shell', 'r', 'sql', 'sql-msSQL', 'sql-mySQL', 'sql-mariaDB', 'sql-sqlite', 'sql-cassandra', 'sql-plSQL', 'sql-hive', 'sql-pgSQL', 'sql-gql', 'sql-gpSQL', 'sql-sparkSQL', 'sql-esper')] | None

default: None

The language to display the code as. Supported languages listed in gr.Code.languages.
every

float | None

default: None

If value is a callable, run the function 'every' number of seconds while the client connection is open. Has no effect otherwise. The event can be accessed (e.g. to cancel it) via this component's .load_event attribute.
lines

int

default: 5

label

str | None

default: None

The label for this component. Appears above the component and is also used as the header if there are a table of examples for this component. If None and used in a gr.Interface, the label will be the name of the parameter this component is assigned to.
interactive

bool | None

default: None

Whether user should be able to enter code or only view it.
show_label

bool | None

default: None

if True, will display label.
container

bool

default: True

If True, will place the component in a container - providing some extra padding around the border.
scale

int | None

default: None

relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True.
min_width

int

default: 160

minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first.
visible

bool

default: True

If False, component will be hidden.
elem_id

str | None

default: None

An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles.
elem_classes

list[str] | str | None

default: None

An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles.
render

bool

default: True

If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later.
key

int | str | None

default: None

if assigned, will be used to assume identity across a re-render. Components that have the same key across a re-render will have their value preserved.

Event Listeners

Description

Event listeners allow you to capture and respond to user interactions with the UI components you've defined in a Gradio Blocks app. When a user interacts with an element, such as changing a slider value or uploading an image, a function is called.

Supported Event Listeners

The Code component supports the following event listeners. Each event listener takes the same parameters, which are listed in the Event Arguments table below.

Listener Description

Code.languages(fn, ···)

['python', 'markdown', 'json', 'html', 'css', 'javascript', 'typescript', 'yaml', 'dockerfile', 'shell', 'r', 'sql', 'sql-msSQL', 'sql-mySQL', 'sql-mariaDB', 'sql-sqlite', 'sql-cassandra', 'sql-plSQL', 'sql-hive', 'sql-pgSQL', 'sql-gql', 'sql-gpSQL', 'sql-sparkSQL', 'sql-esper', None]

Code.change(fn, ···)

Triggered when the value of the Code changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See .input() for a listener that is only triggered by user input.

Code.input(fn, ···)

This listener is triggered when the user changes the value of the Code.

Code.focus(fn, ···)

This listener is triggered when the Code is focused.

Code.blur(fn, ···)

This listener is triggered when the Code is unfocused/blurred.
