"language" attribute of the "TextArea" widget is not working

[Kalebe16]

This is my code(I copied from the official documentation):

from textual.app import App, ComposeResult
from textual.widgets import TextArea

TEXT = """\
def hello(name):
    print("hello" + name)

def goodbye(name):
    print("goodbye" + name)
"""


class TextAreaExample(App):
    def compose(self) -> ComposeResult:
        yield TextArea.code_editor(TEXT, language="python")



if __name__ == "__main__":
    app = TextAreaExample()
    app.run()

Command used

This is the result

Extra observations

• My operating system: Ubuntu
• My terminal emulator: Tabby(I also tested it on the standard Ubuntu terminal)
• My python package manager: pip
• My python version: 3.12.1
• I am using an isolated virtual environment
