Ben Fritz gave you the following solution on vim_use:
--remote-send ':ruby delete_line(1)<CR>'
which I think is as economical ("as elegant" as a math teacher would
say) as you could get. I might add that you would maybe want to test
for Ruby support -- something like (untested):
--remote-send ':if has("ruby") | exe "ruby_delete_line(1)" | else |
echoerr "Sorry, no ruby" | endif<CR>'
(all on one line, and with single quotes around the whole to force the
Unix-like shell to pass the | as part of the parameter). I wrap the
ruby statement in an exe so that Vim versions without ruby support
would not try to parse it.
However you could delete the first line more easily without calling
ruby:
--remote-send ':1d<CR>'
(which is still an ex-command) or
--remote-send ggdd
In the latter case I think the quotes can be omitted since there are
no embedded spaces and no risk of interpretation by the shell.
Best regards,
Tony.
