Running Example

Using string manipulation

ex259 is
  strings := ["a-b_c,d", "-a--cc_,eee,ffff_", "---", ",_-", "abcd", ""]

  for s in strings do
    parts := s.replace "_"  ","
              .replace "-"  ","
              .split ","

    say "\"$s\" : $parts"

What are effects?

Alternative, more elegant, approach using String.fields_func
Note that this treats multiple neighboring seperators as one, so no empty strings are added in that case.

ex259 is
  strings := ["a-b_c,d", "-a--cc_,eee,ffff_", "---", ",_-", "abcd", ""]

  seperators := container.set_of_ordered [",", "-", "_"]

  for s in strings do

    parts := s.fields_func (∈ seperators)

    say "\"$s\" : $parts"
