v0.6.0

Just focus

This release features automatic window focus events support for the Input and Text components.

Note that if you're using Huh in a larger Bubble Tea program you’ll need WithReportFocus to enable focus events.

p := tea.NewProgram(model{}, tea.WithReportFocus())

Happy focusing!

v0.5.0

This big news in this release is that forms in Huh can now be dynamic. Read on for more:

Dynamic Forms 🪄

huh? forms can now react to changes in other parts of the form. Replace properties such as Options, Title, Description with their dynamic counterparts: OptionsFunc, TitleFunc, and DescriptionFunc to recompute properties values on changes when watched variables change.

Let’s build a simple state / province picker.

var country string
var state string

The country select will be static, we’ll use this value to recompute the
options and title for the next input.

huh.NewSelect[string]().
    Options(huh.NewOptions("United States", "Canada", "Mexico")...).
    Value(&country).
    Title("Country").

Define your Select with TitleFunc and OptionsFunc and bind them to the
&country value from the previous field. Whenever the user chooses a different
country, the TitleFunc and OptionsFunc will be recomputed.

Important

We have to pass &country as the binding to recompute the function only when
country changes, otherwise we will hit the API too often.

huh.NewSelect[string]().
    Value(&state).
    Height(8).
    TitleFunc(func() string {
        switch country {
        case "United States":
            return "State"
        case "Canada":
            return "Province"
        default:
            return "Territory"
        }
    }, &country).
    OptionsFunc(func() []huh.Option[string] {
        opts := fetchStatesForCountry(country)
        return huh.NewOptions(opts...)
    }, &country),

Lastly, run the form with these inputs.

err := form.Run()
if err != nil {
    log.Fatal(err)
}

v0.4.2

Your favourite files 📁

Huh? v0.4.0 (v0.4.2) introduces the File Picker to forms ✨

Prompt users to select a file in just a few lines of code, you know the drill :)

var file string

huh.NewFilePicker().
    Title("Select a file:").
    Description("This will be your profile image.").
    AllowedTypes([]string{".png", ".jpeg", ".webp", ".gif"}).
    Value(&file)

---

Field Interface

Zoom

File pickers introduce a new Zoom method to the Field interface.

type Field interface {

    // ...

    Zoom() bool

    // ...

}

Zoom tells the form whether this field should be the only visible field.

Notice how the FilePicker field zooms in when selecting a file and zooms out when the file is selected, showing only the selected file.

Skip

Notes introduce a new Skip method to the Field interface.

type Field interface {

    // ...

    Skip() bool

    // ...

}

Skip indicates to the form whether or not to skip this field, i.e. don't let the user interact with it. This is useful for notes to be purely informational.

v0.3.0

Scrolling, autocomplete, smaller binaries and more!

This is a big release with a tonne of new features.

• Scrollable Forms
• Scrollable Selects and Multi selects
• Autocomplete for inputs
• 7x smaller binaries
• Multi select filtering
• Lotsa' bugfixes and quality-of-life improvements

To upgrade to huh v0.3.0:

go get -u github.com/charmbracelet/huh@latest

For details read on!

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.

v0.2.3

Better Defaults!

Huh? v0.2.3 fixes some bugs for more consistent behaviour across inputs 🐞

• Text inputs now update values on each keystroke rather than on Blur for consistency.
• Select and MultiSelect read their default values from the initial values set by the Value variable if provided.

A special thanks to @vitor-mariano for all his contributions to this release 🤗

Defaults Example

You can now have preselected options by declaring them in the Value variable:

var toppings = []string{"Lettuce", "Tomatoes"}
var options = huh.NewOptions("Lettuce", "Tomatoes", "Charm Sauce", "Cheese", "Vegan Cheese")

huh.NewMultiSelect[string]().Title("Toppings").Options(options...).Value(&toppings).Run()

In the above example, Lettuce and Tomatoes will be preselected by default.

What's Changed

• Text value updates by @vitor-mariano in #64
• Prefill Select and MultiSelect inputs with default values by @vitor-mariano in #62
