Scrollable forms

If a form is in a small terminal it will automatically resize to fit the available space and the active group will scroll to stay in view. Form heights can also be set manually with the new WithHeight method.

Select and Multi select Scrolling

Select and Multi select fields can now be restricted to a certain height, allowing their options to be scrollable. This means you can now pack in tonnes of options.

To make a Select or MultiSelect scrollable simply set the height on the field or form through the Height method.

s := huh.NewSelect()
    .Title("What’s for dinner?")
    .Options(/* ... */)
    .Height(height)

Autocomplete

Now Inputs can offer suggestions making it easier for users to fill out inputs. These suggestions can be accepted autocomplete-style with a configurable key binding (which defaults to ctrl+e).

Simply provide a []string to Suggestions to enable this feature.

huh.NewInput().
    Title("What's for lunch?").
    Prompt("? ").
    Suggestions([]string{
        "Artichoke",
        // ...
        "Cashew Apple",
        "Cashews",
        "Cat Food",
        "Coconut Milk",
        "Cucumber",
        "Curry Paste",
        "Currywurst",
        // ...
    })

More helpful help

Forms will automatically adjust their help text to indicate to the user whether the form will continue or submit on actions. This works with hidden groups. In the below example, the user will be asked to list their allergies if they select "Yes" otherwise, the form will submit.

Way smaller binaries

Huh now produces way smaller binaries! Thanks to #94 Huh now has a 7x smaller compiled footprint.
