# Elm-Ui-Widgets
|
|
|
|
This package contains **independent** widgets (no components) written for [Elm-Ui](https://dark.elm.dmy.fr/packages/mdgriffith/elm-ui/latest/). These widgets have no dependencies to other parts of this package. So you can just use as much as you need.
|
|
|
|
It also supports custom themes and has a material design theme already ready to use.
|
|
|
|
[Examples of all widgets can be found here](https://orasund.github.io/elm-ui-widgets/2.0.0/).
|
|
|
|
|
|
|
|
## Concept
|
|
|
|
**Summary**
|
|
|
|
* Each widget comes with a _Widget Type_ and a _Style Type_. The Widget Type is an abstract representation of the widget and the Style Type has all styling attributes.
|
|
* Widget Types can be used as building Blocks for more complicated Widgets
|
|
(Button -> Select Buttons -> Menu -> Layout)
|
|
|
|
**Example**
|
|
|
|
Let's look at the button widget.
|
|
|
|
```elm
|
|
button: ButtonStyle msg
|
|
->
|
|
{ text : String
|
|
, icon : Element Never
|
|
, onPress : Maybe msg
|
|
}
|
|
-> Element msg
|
|
```
|
|
|
|
In comparison to Elm-Ui's button, we see that `List (Attribute msg)` has changed into a _Style Type_.
|
|
```
|
|
type alias ButtonStyle msg =
|
|
{ container : List (Attribute msg)
|
|
, labelRow : List (Attribute msg)
|
|
, ifDisabled : List (Attribute msg)
|
|
, ifActive : List (Attribute msg)
|
|
}
|
|
```
|
|
|
|
For actually displaying the button we have a few different implementations:
|
|
|
|
``` elm
|
|
{-| Button with only an icon and no text -}
|
|
iconButton :
|
|
ButtonStyle msg
|
|
->
|
|
{ text : String --for screen readers
|
|
, icon : Element Never
|
|
, onPress : Maybe msg
|
|
}
|
|
-> Element msg
|
|
|
|
{-| Button with a text but no icon -}
|
|
textButton :
|
|
ButtonStyle msg
|
|
->
|
|
{ textButton
|
|
| text : String
|
|
, onPress : Maybe msg
|
|
}
|
|
-> Element msg
|
|
|
|
{-| Button with both icon and text -}
|
|
button :
|
|
ButtonStyle msg
|
|
->
|
|
{ text : String
|
|
, icon : Element Never
|
|
, onPress : Maybe msg
|
|
}
|
|
-> Element msg
|
|
```
|
|
|
|
We also have a `Widget Type` for the button:
|
|
|
|
```
|
|
type alias Button msg =
|
|
{ text : String
|
|
, icon : Element Never
|
|
, onPress : Maybe msg
|
|
}
|
|
```
|
|
|
|
We can use it to build more complex widgets, for example a select button:
|
|
|
|
```
|
|
type alias Select msg =
|
|
{ selected : Maybe Int
|
|
, options :
|
|
List
|
|
{ text : String
|
|
, icon : Element Never
|
|
}
|
|
, onSelect : Int -> Maybe msg
|
|
}
|
|
|
|
select :
|
|
Select msg
|
|
-> List ( Bool, Button msg )
|
|
|
|
selectButton :
|
|
ButtonStyle msg
|
|
-> ( Bool, Button msg )
|
|
-> Element msg
|
|
```
|
|
|
|
## Reusable Views vs. Components
|
|
|
|
In Elm we like to use reusable views instead of components.
|
|
At first this packages had a few components, but they where so complicated to use in comparison, so they got slowly turned into reusable views one by one.
|
|
|
|
Most could be reduced even further into _view functions_: reusable views without a model.
|
|
Currently we have only three reusable views: `Widget.Layout`, `Widget.ScrollingNav` and `Widget.Snackbar`.
|
|
|
|
## Alternatives
|
|
|
|
For comparison, here are some alternative packages for creating UIs:
|
|
|
|
* **Using Elm-Ui**
|
|
* [lucamug/style-framework](https://dark.elm.dmy.fr/packages/lucamug/style-framework/latest/) - Full customization requires the cloning of the package.
|
|
* [jxxcarlson/elm-widget](https://dark.elm.dmy.fr/packages/jxxcarlson/elm-widget/latest/Widget-Button) - Uses a Builder pattern. Has some redefined customizations.
|
|
* [QiTASC/hatchinq](https://dark.elm.dmy.fr/packages/QiTASC/hatchinq/latest/) - Similar Arroach but still in experimental phase
|
|
* **Using Elm/Html**
|
|
* [nathanjohnson320/elm-ui-components](https://dark.elm.dmy.fr/packages/nathanjohnson320/elm-ui-components/latest/) - Uses the elm/html way of styling.
|
|
* [NoRedInk/noredink-ui](https://dark.elm.dmy.fr/packages/NoRedInk/noredink-ui/latest/) - Similar Approach but no customization options.
|
|
* [peterszerzo/elm-natural-ui](https://dark.elm.dmy.fr/packages/peterszerzo/elm-natural-ui/latest) - Uses custom Attributes with some customization.
|
|
* **Ui Frameworks**
|
|
* [aforemny/material-components-web-elm](https://dark.elm.dmy.fr/packages/aforemny/material-components-web-elm/latest/) - Wrapper of Material design using custom elements.
|
|
* [afidegnum/elm-tailwind](https://dark.elm.dmy.fr/packages/afidegnum/elm-tailwind/latest/) - Wrapper of Tailwind by including the tailwind stylesheet.
|
|
* [surprisetalk/elm-bulma](https://dark.elm.dmy.fr/packages/surprisetalk/elm-bulma/latest/) - Wrapper for Bulma by including the bulma stylesheet.
|
|
* [rundis/elm-bootstrap](https://dark.elm.dmy.fr/packages/rundis/elm-bootstrap/latest/) - Wrapper for Bootstrap by including the bootstrap stylesheet.
|
|
* [supermacro/elm-antd](https://package.elm-lang.org/packages/supermacro/elm-antd/latest/) - Implementation of Ant Design in Elm
|
|
|
|
## Motivation
|
|
|
|
After looking at the current packages that implement various reusable views (and components) I noticed two things:
|
|
|
|
* There are (nearly) no widgets for Elm-Ui, and that's a problem because while going from `Element` to `Html` is easy, the opposite is not always possible (as a lot of styling in Elm-Ui would not be adapted to the `Html` element.)
|
|
* There is collection of widgets, all in one place. A lot of components get reimplemented over and over again. It's hard to keep track of what package is currently the best.
|
|
|
|
This package tries to solve both of these problems.
|
|
|
|
## Changelog
|
|
|
|
* **Version 2.0.0** - Complete rewrite of the package. Now including a material design implementation.
