Above pseudo-code translated to a function wrapped in a while loop.
function! Footnotes2()
:normal G
:while search('^\[\d\+\]$', 'bc')
:normal va]
:normal y
:let b:p='\'.@0
:execute "call search(b:p)"
:execute "call search(b:p)"
:normal dd
:normal 0
:normal D
:execute "call search(b:p)"
:normal h
:normal r^
:normal ll
:normal P
:normal l
:normal dt]
:normal G
:endwhile
endfunc
I prefer a function for flexibility: I can easily add pre-processing
& post-processing code - e.g. to reflow multi-line footnotes... remove
the NULL lines at EOF... etc.
Thanks,
CJ
