as I was looking for a letterhead recipe. The example shown in Chapter
2 of the book worked flawlessly with groff 1.22.4 on Debian 11, so I
have tilted back in favor of MM now having created my own letterhead in
I wish I had written it. Quite useful.
I tend to use embedded Postscript to help with letterheads if I need
graphics or color or some weird font.
What I have been able to ascertain is that MM was an evolution and
extension of MS by Bell Labs as both originated there.
Hmmm. Not sure. I think young Doug was there when they both started and
could enlighten us. I am talking about the MM that was available in PWB
UNIX. It dates from 1977. I thought that the MS paper was dated 1978. I
started using in 1979 so they were both available at that time. So the
true history predates me. As I said, Doug would be the authority on it.
I find 'DT' referenced in the description of the ISODATE macro and
nowhere else in the page (groff 1.22.4; the string is completely removed
in the Git HEAD of contrib/mm/groff_mm.7.man), yet it works just fine.
It is defined in
.als DT cov*new-date
IMO it should be included in the "strings used in mm" subsection. Is
there a reason why it is not and why its mention has been removed
completely rather than expanded?
You are so right. Looks like a manual page error.
One drawback to MM is the lack of native super/subscript macros.
However, I lifted the superscript formulas from s.tmac and include their
definitions at the top of my letterhead file, appropriately named
SUP/SUPX as borrowed from MOM. ;-)
Why not use the preprocessor eqn(1) which means using definining the
delimiter at the start of the document with
at the start of your document and then use (say)
#x sup 2#
within the text.
