API

new Parser(keywordspec)

Creates a new parser. The keywordspec parameter is optional, with the default being:

{
  gettext: ['msgid'],
  _: ['msgid'],

  ngettext: ['msgid', 'msgid_plural'],
  n_: ['msgid', 'msgid_plural'],

  pgettext: ['msgctxt', 'msgid'],
  p_: ['msgctxt', 'msgid'],

  npgettext: ['msgctxt', 'msgid', 'msgid_plural'],
  np_: ['msgctxt', 'msgid', 'msgid_plural']
}

Each keyword (key) requires array of strings indicating the order of expected PO fields. For example npgettext: ['msgctxt', 'msgid', 'msgid_plural'] indicates that the npgettext handlebars helper takes arguments of form {{npgettext "context" "string" "plural" ...}}

.parse(template)

Parses the template string for Handlebars expressions using the keywordspec. It returns an object with this structure:

{
  msgid1: {
    line: [1, 3]
  },
  msgid2: {
    line: [2],
    plural: 'msgid_plural'
  },
  context\u0004msgid2: {
    line: [4]
  }
}
