Is there a command to delete a line (or several lines) that is immediately below current line? Cur开发者_如何学Pythonrently I'm doing it as: jdd and then . to repeat as needed. Is there a command that would combine all these?
UPDATE: The reason I would like to have such command is that I don't like to move away from current position, yet be able to delete lines below.
The delete ex command will work nicely.
:+,$d
This will delete all the lines from current +1 till the end ($)
To delete the next 2 lines the follow range would work, +1,+2
or shorthand +,+2
:+,+2d
As @ib mentioned the :delete
or :d
command will move the cursor to the start of the line next to the deleted text. (Even with nostartofline
set). To overcome this we can issue the ``
normal mode command. ``
will jump back to the exact position before the last jump, in this case the :d
command. Our command is now
:+,+2denter``
Or as one ex command
:+,+2d|norm! ``
To make this easier we wrap this all up in a command:
command! -count=1 -register D :+,+<count>d <reg><bar>norm! ``
Now to delete the next following 3 lines:
:3D
This command can also take a {reg}
like :delete
and :yank
do. So deleting the next 4 lines into register a
would be:
:4D a
For more information
:h :d
:h :command
:h :command-register
:h :command-count
:h ``
dG should work.
This means delete all rows until end of file from current cursor.
This will delete ALL lines below the current one:
jdG
Unfortunately that will move the cursor to the beginning of current line after the deletion is made.
well, to do it simply you could use the xxdd command. Most of the time I know (at least have an idea) the size of the script I am editing. So, the command as below is usually more than enough :
- 99dd
- 999dd to remove 999lines starting at the cursor position.
- 9999dd
- 99999dd for very long script ;)
The other solutions are informative, but I feel it'd be simpler to use a macro for this:
qq
(begins recording)
jddk
(go down, delete the line, and go back up - i.e. the thing you want to do)
q
(end recording)
Now you can do @q
to perform this action, maintaining the cursor at the current position. You could also do something like 5@q
to delete 5 lines below the cursor.
And finally, if you're repeating the action more than once, you could just type @@
after the first time you run @q
(this repeats the last used macro - in this case q
)
This is a job for marks!
Try maj20dd`a
ma
sets the file-specific mark 'a', j20dd
does the deletion you want (20 lines in this case), and `a
restores you to the mark's position (line and column).
Obviously this pattern can be extended to do anything you want before returning to the mark. If you use mA
(or any other capital letter) the mark will actually be unique across files, so you can even edit elsewhere before returning. If you have a very frequent usage you could make it a macro as suggested above.
You could enter the number of lines to delete: j 20 dd k.
Just for the fun of it, you can define a little function that does
exactly what you described: deletes the next n
lines below the
current line and restores the initial cursor position.
function! DeleteNextLines(n, reg)
let l = line('.')
let m = min([a:n, line('$')-l])
if m > 0
let c = col('.')
exe '+,+'.m 'd' a:reg
call cursor(l, c)
endif
endfunction
Also, you can define a command that accepts the number of lines
to delete (one, if omitted) and the register name to use as an
optional argument (just like the :delete
command).
:command! -range=1 -register -bar D call DeleteNextLines(<count>, <q-reg>)
Additionally, you can define a mapping for triggering the above
:D
command, if it is necessary.
