// ### Content Helper | |
// | |
// *Usage example:* | |
// `{{content}}` | |
// `{{content words="20"}}` | |
// `{{content characters="256"}}` | |
// `{{content preview="true"}}` | |
// `{{content preview="true" words="20"}}` | |
// | |
// Turns content html into a safestring so that the user doesn't have to | |
// escape it or tell handlebars to leave it alone with a triple-brace. | |
// | |
// Enables tag-safe truncation of content by characters or words. | |
// | |
// If preview option is used then only the content before <!--preview--> is returned. | |
// | |
// **returns** SafeString content html, complete or truncated. | |
// | |
coreHelpers.content = function (options) { | |
var truncateOptions = (options || {}).hash || {}; | |
truncateOptions = _.pick(truncateOptions, ['words', 'characters', 'preview']); | |
_.keys(truncateOptions).map(function (key) { | |
truncateOptions[key] = parseInt(truncateOptions[key], 10); | |
}); | |
if (truncateOptions.hasOwnProperty('preview')) { | |
var split = this.html.split('<!--preview-->', 2) | |
if (split.length > 1) { | |
return new hbs.handlebars.SafeString(split[0]) | |
} | |
} | |
if (truncateOptions.hasOwnProperty('words') || truncateOptions.hasOwnProperty('characters')) { | |
// Due to weirdness in downsize the 'words' option | |
// must be passed as a string. refer to #1796 | |
// TODO: when downsize fixes this quirk remove this hack. | |
