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>.
