[9fans] troff macro II

[9fans] troff macro II

[Rudolf Sykora]

Hello 9fans,

since in the previous thread started by me ('troff macros for
typesetting books/longer texts') nobody touched my question about
producing wanted headings, I started experimenting, but so far has not
been quite successful.

Since text to appear in my headings is to mirror section names, like
'1.2', and a beginning of such a section appears somewhere lower on a
page---definitely below the page heading---, I must create a page
heading just after the very page is filled, i.e., as I feel, the
heading could actually be produced when the ms .BT macro (usually used
to typeset footings) is called. So I naively tried to redefine the .BT
macro, actually, by just appending 4 extra lines:

.de BT
.nr PX \\n(.s
.nr PF \\n(.f
.ft 1
.ps \\n(PS
'lt \\n(LTu
.po \\n(POu
.if \\n%>0 .tl \(ts\\*(LF\(ts\\*(CF\(ts\\*(RF\(ts
.ft \\n(PF
.ps \\n(PX
.\"  ABOVE IS THE ORIGINAL, BELOW MY APPENDIX
.mk
\v'|0.5i'
.tl 'a'b'c'
.rt
..

Please consider this just as an experiment (no point-size changes,...).
This for some reason doesn't work.
Since some of you probably have experience, could sb. tell what is wrong?

Thank you
Ruda

Typing from phone so I'll be brief.

Just put the header at the bottom of the page and pipe the .ps output
through sed to change the vertical position.

I found this easier than moving back up the page in troff.

Ok. That's a 'dirty' solution, a hack. Though possible.
I am looking for a solution within troff, if possible.

Thanks anyway

Read carefully the section 9, 10 and 11 of "A TROFF Tutorial"[1]. I
think is exactly what you are looking for.

DONE!
Try the attached code. I am not using the ms macros. You will to
change the ms macros to get something similar.

troff test.ms | tr2post | psfonts > test.ps

Cheers.

Yes. This works. Actually, my problem has always only been: how to get
back to the top of a page; to have a correct string prepared to put
there has been easy for me. Note what I wrote in my 1st post of this
thread:
.
.\"  ABOVE IS THE ORIGINAL, BELOW MY APPENDIX
.mk
\v'|0.5i'
.tl 'a'b'c'
.rt
..

and it comes in a modified .BT macro (which is somewhat equivalent to
your .NP; ms actually sets [as far as I know] 3 traps on a page, 1 at
the top [.NP] and 2 at the bottom [.FO a .BT]). If I had written just
.
.\"  ABOVE IS THE ORIGINAL, BELOW MY APPENDIX
.tl '\v'-10.5i'a'b'c\v'+10.5i''
..

as you have, it would have basically done what I want. So now the
question is why
.tl '\v'-10.5i'a'b'c\v'+10.5i''
moves back and does the work, whilst
.mk
\v'|0.5i'
.tl 'a'b'c'
.rt
does not.
Nor does this, for instance:
\v'-10.5i'
.tl 'a'b'c'
\v'+10.5i'

Thanks for your help

Becouse "The backslash character \ is used to introduce troff commands
and special characters *within* a line of text" (from the Troff
tutorial)

Try:
.\"  ABOVE IS THE ORIGINAL, BELOW MY APPENDIX
.mk
.tl '\v'-10.5i'a'b'c\v'+10.5i''
.rt
..

Also to pay attention to the command .wh  in my example:

.wh -1i NP \" When you reach the final of the page less 1 inch call
the command .NP
