[9fans] line numbers in troff

[9fans] line numbers in troff

[hugo rivera]

Hello,
usually, when writting drafts for somebody else to review, its useful
to have line numbers printed at the beginning of each line.
How would you implement that in troff? I never written a macro in
troff, so some basic pointers would be enough for me (e.g. some good
troff book).
Thanks,

macros are easy enough: start them with .de XX and end them with .., e.g.
start and end code example which I end up adding to most documents I write:

.de EX
.nj
.nf
.CW
.SM
..

.de EE
.fi
.ju
.LG
.R
..

There are quite a few books, see http://www.troff.org/ , my favorite is
"Document formatting & typsetting on the UNIX system".

I really don't know how you would add line numbers, if you are lucky there
may be a well-known macro which is run at the start of every line...

Funny you should mention this. I know there is a way (done for patent
applications). I think I can find it in the troff doc. I have to by
tomorrow so I'll report back.

I think at the top of the page you set a trap to go off at the next line.
In the trap macro you reset the trap for the line after that.  And so on,
down the page.

.nm 1 M   numbers every M lines following

there are other options
