[erlang-questions] Formatting strings with named arguments

[Imants Cekusins]

io_lib:format
substitutes multiple placeholders, converts to string, does padding.

You could
1) search for named placeholders using re:run

2) replace placeholders with ~s or ~p using re:replace

3) prepare a list with substitutes from a map|dict

4) pass this list to io_lib:format.

A bit of work but doable.
