Textual Inputs is a collection of input widgets for the Textual TUI framework.
Thanks to all the developers who contributed or used Textual Inputs. These widgets filled a gap in the early stages of Textual, which is now supported natively. Special thanks to @willmcgugan for creating this fun and functional framework -> Textual Widget Docs
Installation

Textual Inputs takes advantage of rich's built-in Syntax feature. To
add highlighting to your input text set the syntax argument to a language
supported by pygments. Currently this is set to the default theme.
TextInput(
name="code",
placeholder="enter some python code...",
title="Code",
syntax="python",
)Textual Inputs helps make the event handler process easier by providing the following convenient properties for inputs.
- on_change_handler_name
- on_focus_handler_name
email = TextInput(name="email", title="Email")
email.on_change_handler_name = "handle_email_on_change"
email.on_focus_handler_name = "handle_email_on_focus"Under the hood setting this attribute this will generate a Message class
with the appropriate name for Textual to send it to the handler name provided.
You'll then want add the handler to the input's parent or the App instance.
If you opt not to customize these handlers, their values will be the
default handle_input_on_change and handle_input_on_focus. See
examples/simple_form.py for a working example.
