erlang-syntax-tools - 1:23.2.6+dfsg-1+deb11u1 main

Syntax_Tools contains modules for handling abstract Erlang syntax
trees in a way that is compatible with the "parse trees" of the
STDLIB module erl_parse, together with utilities for reading source
files in unusual ways and pretty-printing syntax trees. Also it
includes a module merger and renamer called Igor, as well as an
automatic code-cleaner.
