I already shared this answer by private email, but I decided today to
subscribe to the group so I'm going to share my answer with this group
too.
I recently (just last week) decided to implement the same sort of plugin.
After examining the visswap.vim plugin, I concluded that the best way to
do this sort of thing is as follows:
old_x=VIM.evaluate('@x') #first save the old x register
VIM.command(':normal! vgv"xy') #then yank selection into the x register
selection=VIM.evaluate('@x') #then get the contents of x register
#do ruby stuff on the selection
#set the value of the X register
VIM::evaluate("setreg('x',\"#{result.vim_escape}\")")
VIM::command(':normal! vgv"xP') #paste x register
#finally, restore x register
VIM::evaluate("setreg('x',\"#{old_x.vim_escape}\")")
And of course, somewhere earlier in the script I have defined
class String
#escapes a string so it can be concatenated into
#a call to VIM.evaluate
def vim_escape
result=dup
result.gsub!("\\",'\\\\\\\\')
result.gsub!('"','\"')
result
end
end
