production-quality template convention to scrap web sites based on cheerio
## Installation
```bash
$ npm install menio
```
## A Menio template
```javascript
module.exports = {
// Selector
context: {
selector: 'table > tr',
index: 4
},
// Properties
props: {
render: function ($scope) {
var numeros = $scope.$find('tr');
// return scope and next = true if this only selects for another template, only available in callback mode
return {
$scope: numeros,
next: true
};
}
}
};
```
## Another Menio template
```javascript
module.exports = {
context: 'td',
props: {
tipo: function ($scope) {
// either return or assign to this.model
return $scope.eq(0).text();
},
fecha: function ($scope) {
return $scope.eq(1).text();
},
primero: function ($scope) {
return {
numero: $scope.eq(2).text(),
serie: $scope.eq(4).text(),
folio: $scope.eq(5).text(),
verificacion: $scope.eq(6).text(),
letras: $scope.eq(3).text()
};
},
segundo: function ($scope) {
return {
numero: $scope.eq(7).text()
};
},
tercero: function ($scope) {
return {
numero: $scope.eq(8).text()
};
},
dateFormatISO: function () {
return 'es-pa';
},
id: function($scope) {
return this.tipo($scope) + this.fecha($scope);
}
}
};
```
### Menio Docs
#### new Menio(templateDirectory)
#### menio.parse(htmlOrDOM, templateName, callback)
#### menio.render(options { template, data }, callback)
#### Callback(err, scope, model)
### Menio Template Docs
#### Property(scope, cheerio, underscore)
#### Property(scope, cheerio, underscore)
#### Response(either value or options)
#### Response Options($scope, next), only available in callback mode
### Example
```javascript
// add template directory
var menio = new Menio(__dirname + '/templates');
// async callback
// 1st argument - either a $ element or HTML
// 2nd argument - name of the template
// 3rd and optional - callback
menio.parse(html, 'loteria', function (err, $scope) {
// callback returns error, scope and model
var data = _.map(_.rest($scope, 3), function (row) {
// sync returns results right away
return menio.render({ template: 'row', data: row });
});
var matchWith = {
tipo: 'Dominical',
fecha: '01-09-2013',
primero: {
numero: '0677',
serie: '4',
folio: '13',
verificacion: '',
letras: 'DDBC'
},
segundo: {
numero: '7260'
},
tercero: {
numero: '8783'
},
dateFormatISO: 'es-pa',
id : 'Dominical01-09-2013'
};
expect(data[0]).toEqual(matchWith);
});
});
```
### Changelog
* 0.2.0: Better API with $scope.$find, context selector index and added render (same as parse) which accepts an options argument
