Description

The mdoc documentation (details/recursion) goes through many ways to achieve recursion and iteration with the roff language. It goes through the following topics:

• recursive macro expansion,
• recursive string expansion,
• recursive macro content addition,
• recursive macro definition,
• recursive file inclusion,
• iteration.

The self-redefining macro written by Ingo Schwarze (details/redefine_self) is another example of recursion. The macro implements an arbitrary payload and uses it to show the Fibonacci sequence.
