Instance Method Details

#parse(file, _msgids = []) ⇒ Object

We’re lazy and clumsy, so this is a regex based parser that looks for invocations of the various gettext functions. Once captured, we scan them once again to fetch all the function arguments. Invoke regex captures like this:

javascript source: “#{ __(‘hello’) } #{ __(”wor)ld“) }” matches: [0]: __(‘hello’) [1]: __ [2]: ‘hello’

javascript source: __(‘item’, ‘items’, 33) matches: [0]: __(‘item’, ‘items’, 33) [1]: __ [2]: ‘item’, ‘items’, 33

handlebars source: “_ ”foo“}” matches: [0]: __(‘foo’) [1]: __ [2]: ‘foo’

handlebars source: “_ ”foo“ ”foos“ 3}” matches: [0]: __(‘foo’, ‘foos’, 3) [1]: __ [2]: ‘foo’, ‘foos’, 3

The PO file outputs to a “” string. single quotes are unescaped (if they are escaped) double quotes are escaped (if they are not already escaped)
