API

new Parser(keywordSpec)

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

{
  _: {
    msgid: 0
  },
  gettext: {
    msgid: 0
  },
  dgettext: {
    msgid: 1
  },
  dcgettext: {
    msgid: 1
  },
  ngettext: {
    msgid: 0,
    msgid_plural: 1
  },
  dngettext: {
    msgid: 1,
    msgid_plural: 2
  },
  pgettext: {
    msgctxt: 0,
    msgid: 1
  },
  dpgettext: {
    msgctxt: 1,
    msgid: 2
  }
}

Each keyword (key) requires an object with argument positions. The msgid position is required. msgid_plural and msgctxt are optional. For example gettext: {msgid: 0} indicates that the Swig expression looks like {{ "string"|gettext }}.

.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]
  }
}
