An calendar extension for Webpop for sorting entries that occur in the future into months.

calendar.js

// Use <pop:calendar:months> within the scope of entries to generate
// a timeline array of all the months which have entries
exports.months = function(options) {
  if (!section) return null;
  
  var result = site.search({
    all: true,
    filters: {section: section, date: "future" },
    timeline: {date: "month"},
  }).timeline;
    
  return result;
  // Returns a simple array of months with 'start' & 'end' atrributes
};

// Use <pop:entries_for start="<pop:start/>" end="<pop:end/>"> inside of <pop:calendar:months> 
// to render a collection of entries with a date between the specified 'start' and 'end' date.

exports.entries_for = function(options) {
  if (!section) return null;
  
  var start = new Date(options.start), end = new Date(options.end);
  
  if ( new Date() > start )
    start = new Date()
  
  var results = site.search({
    all: true,               
    filters: {section: section, date: {from: start, to: end}},
    order: "date ASC"
  }).results;
  
  return results;
  // Returns an array of entries which you can render out
  // in your templates like a regular <pop:entries> tag.
