Public predicates

.. index:: replace_sub_atom/4 .. _atom/0::replace_sub_atom/4:

replace_sub_atom/4 ^^^^^^^^^^^^^^^^^^^^^^

Replaces all occurrences of Old by New in Input returning Output. Returns Input if Old is the empty atom. Fails when Output does not unify with the resulting atom.

| Compilation flags: | static

| Template: | replace_sub_atom(Old,New,Input,Output) | Mode and number of proofs: | replace_sub_atom(+atom,+atom,+atom,?atom) - zero_or_one

---

.. index:: split/3 .. _atom/0::split/3:

split/3 ^^^^^^^^^^^

Splits an atom at a given delimiter into a list of sub-atoms.

| Compilation flags: | static

| Template: | split(Atom,Delimiter,SubAtoms) | Mode and number of proofs: | split(+atom,+atom,-list(atom)) - one
