Thank you all for the help.
I'm using John Beckett's solution now. But I'm interested in learning
how to script Vim with Ruby, and I could use some help with this half-
complete solution.
I wrote the following Ruby Vim script:
function! Headline(char)
ruby << EOF
header_length = $curbuf[ $curbuf.line_number - 1 ].length
$curbuf.append $curbuf.line_number - 1, VIM::evaluate("a:char") *
header_length
EOF
endfunction
:call Headline('-')
will underline the current line with dash characters.
My question is, what's the easiest way to map this function -- which
takes a parameter -- to a key or key sequence?
Many thanks.
