Full description
macrostep is an Emacs minor mode for interactively stepping through the
expansion of macros in Emacs Lisp source code. It lets you see exactly what
happens at each step of the expansion process by pretty-printing the
expanded forms inline in the source buffer, which is temporarily read-only
while macro expansions are visible. You can expand and collapse macro forms
one step at a time, and evaluate or instrument the expansions for debugging
with Edebug as normal. Single-stepping through the expansion is
particularly useful for debugging macros that expand into another macro
form. These can be difficult to debug with Emacs’ built-in macroexpand,
which continues expansion until the top-level form is no longer a macro
call.
