Should have a way of getting names of all inputs

[wch]

Currently, if you want to get the name of all keys in input, you need to do call:

list(input._map)

This is kind of a hack. It should be possible to call list(input) or input.keys() to get the keys.

This app demonstrates (shinylive app):

from shiny import App, render, ui

app_ui = ui.page_fluid(
    ui.h2("All input keys:"),
    ui.output_text_verbatim("txt"),
    ui.input_slider("slider", "A slider", 1, 100, 50),
)


def server(input, output, session):
    @output
    @render.text
    def txt():
        keys = list(input._map)
        keys_values = [f'input["{k}"] = {str(input[k]())}' for k in keys]
        return "\n".join(keys_values)


app = App(app_ui, server)
