Hi,
i write a simple keymap for commenting C file,
map C 0i/*<C-Esc>A*/<C-Esc>j
now i want to use the command like 12C to comment a block, however, it does
not follow my mind, it does not comment one line then go down comment the
next line, it only give a lot of /* in the first line and make mistake, how
to implement what i want?
Thank you very much.
The way you do it, the 12 in 12C is simply prepended to the mapping, changing
it to 120i/*<Esc> etc., i.e., adding /* ten times the count (120 times here),
then */ once at the end of the line.
Method I: Put your command in a register, let's say "q, and invoke that
register with a count:
:let @q = "0i/*\eA*/\ej"
or
:let @q = "i\<Home>/*\<End>*/\<Down>\e"
and in either case
:map C @q
Method II: Use a Visual-mode mapping:
:vmap <F2> <Esc>:'<-1put ='/* '<CR>:'>put =' */'<CR>
or
:vmap <F2> <Esc>:'<-1put ='#if 0'<CR>:'>put ='#endif'<CR>
I recommend the last of the above, which will (if I didn't goof) add "#if 0"
above your (linewise) visual area and "#endif" below it, so than any /* */
inside the block won't disturb the compilation.
(I'm not sure what you use Ctrl-Esc for: I have no help for i_CTRL-Esc and on
my system, the Ctrl-Esc key is preempted by the window manager so that gvim
never sees it.)
Best regards,
Tony.
