blessedoo v0.0.3-a

An incomplete MVC xml wrapper for blessed, a curses-like library. All blessed objects utilize the 'blessed' namespace. All subproperties of the options utilize their own xml subnode.

A basic form would look like this!

<blessed:form top="center" left="center" width="50%" height="50%" content="Hello!">
  <border type="line"></border>
</blessed:form>

Loading views

You can load views by using the blessedoo loadView method:

var blessedoo = require('./blessedoo')();

var context = {
  doStuff: function() {
    console.log('ham');
  },
  doStuff2: function() {
    console.log('meow');
  }
};
blessedoo.loadView('sections/test.xml', context, function(err, result) {
  blessedoo.setView(result);
});

test.xml would look something ugly like this:

<blessed:form top="center" left="center" width="50%" height="50%" content="Hello!" keys="true">
  <border type="line"></border>

  <blessed:button mouse="true" keys="true" shrink="true" padding="1" top="center" left="center" width="50%"  content="Push me!" onpress="doStuff">
    <style bg="blue">
      <focus bg="red"></focus>
      <hover bg="red"></hover>
    </style>
    <border type="line"></border>
  </blessed:button>
  <blessed:button mouse="true" keys="true" shrink="true" padding="1" top="2" left="center" width="50%" content="Me too!" onpress="doStuff2">
    <style bg="blue">
      <focus bg="black"></focus>
      <hover bg="black"></hover>
    </style>
    <border type="line"></border>
  </blessed:button>
</blessed:form>

IDs

The purpose of IDs is to uniquely identify an element. This is similar to HTML.

To retrieve an element, just call blessedoo.getElementById('myUniqueName').

For lists, you MUST do this as there is currently no way to insert items from the XML. It is done after the XML compilation.

  <blessed:list mouse="true" keys="true" shrink="true" padding="1" top="20%" left="center" height="30%" width="100%" id="myListView" selectedFg="blue">
    <border type="line"></border>
  </blessed:list>

  var list = blessedoo.getElementById('myListView');
  list.setItems(['item one', 'item two']);

A simple button example

Using blessedoo, it would look like this:

<blessed:button mouse="true" keys="true" shrink="true" padding="1" top="2" left="20" width="50%" name="button" content="A button!" onpress="someFunctionPassedIntoContext">
  <style bg="blue">
    <focus bg="red"></focus>
    <hover bg="red"></hover>
  </style>
  <border type="line"></border>
</blessed:button>

With the original library, it would look like this: The original blessed library seemed to get confusing very quickly. A simple button would look like this:

var someButton = blessed.button({
  parent: box,
  mouse: true,
  keys: true,
  shrink: true,
  padding: {
    left: 1,
    right: 1
  },
  left: 20,
  top: 2,
  name: 'button',
  content: 'A button!',
  border: {
    type: 'line'
  },
  style: {
    bg: 'blue',
    focus: {
      bg: 'red'
    },
    hover: {
      bg: 'red'
    }
  }
});

someButton.on('press', function() {
  // do stuff
});
