Instance Method Details

#parse_args(arg_str) ⇒ Object

Parses arguments in the form: ‘arg0 ; arg1 ; …|att=val|att2=val|…`

The first portion is the direct argument. For instance, a link like ‘[~ link ; text ~]` or an image like `[! src ; alt !]`. The remaining piped args are key-value pairs (use `\|` to escape) which might be embedded in the tag or signal some further transformations.

Returns:

  • An array where the last element is always a {Hash}
