#gettext_function ⇒ Object
The gettext function name can be configured at the module level as gettext_function.

We’re lazy and klumsy, so this is a regex based parser that looks for invocations of the various gettext functions.
Instance Attribute Details
#gettext_function ⇒ Object
The gettext function name can be configured at the module level as gettext_function. This is to provide a way to avoid conflicts with other javascript libraries. You only need to define the base function name to replace “_” and all the other variants (s_, n_, N_) will be deduced automatically.

Instance Method Details
#parse(file, _msgids = []) ⇒ Object
We’re lazy and klumsy, 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
