Hi!

This is a gentle ping about my terminological reforms about manual page 
chapters.

Cheers,

Alex

That can be documented as a historical detail in the documentation of the option itself, which makes sense, as to avoid programmers that have heard of sections to try to grep section and find nothing.

Yes, especially since part of the discussion is in linux-man@ (I'm not sure if he reads it; I think not) and not in groff@ (which he reads, AFAIK). So, I'll merge the 2 discussions about this by forwarding the 2 most interesting other emails below.

So, does it make sense to all of us to start using the term chapter for divisions of the man-pages single volume, so that the manual pages in Linux are organized from now on in chapters 1 to 9 instead of sections 1 to 9?

Cheers,

Alex

I've got good news for you. I started writing intro(3type), after I got the first contribution of a new page to chapter 3type of the manual.

And while doing it, I found a place where the term 'chapter' is used. It's very likely that there's where I saw it the other time. It's in a comment in the intro(3) page, which seems to be there since there's git history.

The author of the page seems to be Michael Haardt; his last commit to the man-pages is from 2015, so I guess his email is still active. Maybe he can comment. I also CCed aeb and mtk, as they maintained the pages before me and may know if that term was in use at the time.


Cheers,

Alex

Thanks for the prompt reply!
'chapter' definitely makes more sense, at least considering the manual as a book. Since it seems to have been in general use in the past, it's not so much of a breaking change to start using it now again. So, to avoid ambiguity between section referring to a chapter or section referring to part of a page, I'll start using the term [sub]chapter consistently.

With time, I expect to replace all occurrences of section that should be chapter in the man-pages.
