Hi,
I made a private patch for nvi(1) that enable you to use new variable '@'
in arguments of ex's ! or !! command.
The '@' is similar to '%' which means the editing file name.
If you are editing file.c at 110 line then ':!echo @' means ':!echo 110'.
It is convenient to use with gozilla(1).
If you have hypertext of source code generated by htags with -l option then
you can display editing text on mozilla as a hypertext.
:!gozilla +@ %
Suggested .nexrc:
+--------------------------
|map ^G :!gozilla +@ %^M
But this is a serious modification of nvi's spec. You cannot use '@' as a
constant in nvi's shell command line.
So, you had better use this patch personally.
Here is a patch for /usr/src/contrib/nvi/ex/ex_argv.c in freebsd-current.
