Box macro. Do a .mk z where the box is to start, and a .eb
where it is to end. Optional argument is a title to be centered
within the top box line.
Usage:
.mk z
Text, etc to be boxed...
.eb "Optional title goes here"
~or~
.mk z
Text, etc to be boxed...
.eb
Some explanation:
The macro name is eb <.de eb>. First thing we do is to go up on line
<.sp -1> and turn off fill mode <.nf>. Now it gets interesting: the
.ie is the if/else construct. We check the number of arguments provided
to the macro <\\n(.$> and if it is greater than 0 (meaning we have a title),
we do the rest of the .ie line, as follows:
\h'-.5n' - move left one-half of an n
\L'|\\nzu-1' - draw a vertical line <\L> to the
absolute position (|) given by \\nzu-1,
which is the position set with the .mk
command into register z <\\nz> in base
units <u> minus 1.
\l'(\\n(.lu+1n-\w'\\$1'u/2u)\(ul' - Draw a horizontal line <\l> with length
equal to the current line length
<\\n(.l> in base units <u> plus the
space required for an 'n' <1n>, minus
the width <\w> of the title string
<\\$1> in base units <u> divided by 2
<in base units <u>>. Draw the line
using the underline character, <\(ul>.
\v'.3m'\|\\$1\|\v'-.3m' - Move down the page 3/10 of an m,
<\v'.3m'>, output a 1/6 of an m space
<\|>, output the title <\\$1>, another
1/6 of an m space <\|>, and then move
up the page 3/10 of an m <\v'-.3m'>.
\l'...\(ul' - Draw the second part of the line, just
like the corresponding left half done
before.
\L'-|\\nzu+1' - Draw a verticle line <\L> going down
the absolute distance <-|> from where
the macro was given to where the start
point was marked <\\nz> in base units
<u> plus one line <+1>
\l'|0u-.5n\(ul' - Draw a horizontal line to the absolute
position (|0) when the macro was
invoked, minus half an n <-.5n> using
the underline character <\(ul>.
The .el beings the else part, which is identical to the above, except
the string dosen't get printed. This makes the printing of the top
line much easier: just draw a line <\l> with width equal to the
current line plus the witdh of an n <\\n(.l+1n> using the underline
character <.\(ul>.
