Instance Method Details

#parse_args(arg_str, no_direct = false) ⇒ 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.

If any contexts don’t use direct arguments, set {no_direct} to ‘true`. This will produce a 1-element array with a map.

interpreted as a direct arguments list. arguments.

Parameters:

  • String —

    arg_str A pipe-separated argument list, with first argument

  • Boolean —

    no_direct If true, doesn’t treat first argument as direct

Returns:

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