Pennyworth NPM

pennyworth

a natural language templating engine

usage

// build a template from a template string
var template = pennyworth.template('my $adjective template.');

// the template is a function that can be called with data at
// any time and multiple times
template('my beautiful template').then(function (compiled) {
	// it will always return a promise to allow support for
	// asynchronous filters

	console.log(compiled); // { adjective : 'beautiful' }
});

spec

variables

for hello, alfred => $who = alfred
for hello, alfred. how are you? => $who = alfred how are you
for hello, how are you? => $who = how are you

for hello, alfred. => $who = alfred
for hello, alferd. how are you? => $who = alfred
for hello, how are you? => $who =

variable filters

for i am 18 years old. => $x = "18"

for i am 18 years old => $x = 18

Supported filters: string, int, float, word.

Adding a new filter:

pennyworth.filter('my-new-filter', function ( input ) {
	return String(input) + '!';
});

var template = pennyworth.template('hello, $who:my-new-filter.');
template('hello, alfred.').who === 'alfred!'; // true

For asynchronous filters, grab a callback using this.async():

pennyworth.filter('async', function ( input ) {
	let done = this.async();
	done( error , filtered );
});

named entities

pennyworth uses the Stanford NER for named entity filters.

Supported filters (from the 7 class model): Location, Person, Organization, Money, Percent, Date, Time

To use any, just use the entity type as the filter name:

For instance, for the input string My name is Alfred Pennyworth not Wayne Mansion., if you use the filter 'string': My name is $name:string then the resolved name will be "Alfred Pennyworth not Wayne Mansion". But if you use the filter 'person', the output will be "Alfred Pennyworth".
