I am trying to produce a macro for request blm that would set space
as a given fraction of the current vertical spacing.
I did the following:
-------------------------------------------
.de blank
. nr blankreg (c;\\$1) this
would accept things like ".blank 0.42" and convert to "u"
..
.de blank_aux
. sp (\\n[.v]u*\\n[blankreg]u/28340)u this macro would
generate space when .blm finds a blank line
..
.blm blank_aux this
nominates blank_aux to be called by .blm
--------------------------------------------
I know I'm coming in late, but there are two things I'd do
differently: set a default and use relative spacing (v) instead of
machine units (u).
.de blank_aux
. if !rblankreg .nr blankreg 0.4v
. sp \\n[blankreg]u
..
.blm blank_aux
Replace the 0.4v above with whatever you want the default value to be
and it will work with the entire range of devices and text sizes.
