vim note

一个文档包含了这样一行：'a b c d e f g' 光标在b处，这时我可以键入'd/f',第一个d表示删除，/ 表示搜索，所以这个命令表示从b删除到f。

 

xp     This will delete the character under the cursor, and put it
afterwards.  In other words, it swaps the location of two characters.

ddp    Similar to xp, but swapping lines.

yyp    duplicate a line

uu     Undo and redo last change.  (This will take you to the last
modification to the file without changing anything.)  You can also use
this to compare the changes to a line.  Make the changes to the line,
press U to undo the changes to the current line, and then press u to
toggle between the two versions.

:g/.*/m0
This will reverse the order of the lines in the current file.
m0 is the ex command to move the line to line 0.

:v/./d or :g/^$/d
Removes all blank lines.

:g/^[ <ctrl-v><tab>]*$/d
Removes all lines that only have whitespace.

:v/./$s/$/<ctrl-v><enter>./|'';/./-1j|$d
Replaces multiple blank lines with just one blank line.


Swap character and one vertically above:
map * kxjphxkP

Fold a line that's too long
map g $80<ctrl-v><ctrl-v>|F r<ctrl-v><enter>

Change case on most words
map v ywmno<ctrl-v><esc>P:s/./\~/g<ctrl-v><enter>0"nDdd`n@n

Put `and' around the current word
map *` i`<ctrl-v><esc>ea'<ctrl-v><esc>

Put 'and' around the current word
map *' i'<ctrl-v><esc>ea'<ctrl-v><esc>

Put "and" around the current word
map *" i"<ctrl-v><esc>ea"<ctrl-v><esc>

Put `and' around the current word
map! `` <ctrl-v><esc>bi`<ctrl-v><esc>ea'

Split a line at the cursor, and put a > at the beginning of the next
line.  (For quoting Usenet, etc). I had some trouble with my old
version of this under some versions, so I've redone it, and I think
that it should work.
map g may0O<ctrl-v><esc>P`ao<ctrl-v><esc>P:s/./ /g<ctrl-v><enter>0i><ctrl-v><esc>$mb`ay$`bP'add

Insert one character
map g i$<ctrl-v><esc>r

Format a paragraph without the fmt program.  (To use, use J a few
times, then this a few times)
map K 072lBhr<ctrl-v><enter>

Or, a little less elegantly, but without the need to use J and K
multiple times.
map K {wma}b:'a,.j<ctrl-v><enter>:s/\(.........................................................\)/\1<ctrl-v><ctrl-v><ctrl-v><enter>/g<ctrl-v><enter>

Make ctrl-x work as cut, ctrl-v as paste, ctrl-p as copy.  You should
mark the beginning of the area as m (use mm).  (ctrl-c cannot be
remapped when it is defined as the interrupt character in Unix.)
map <ctrl-v><ctrl-x> "zd`m
map <ctrl-v><ctrl-p> "zy`m
map <ctrl-v><ctrl-v><ctrl-v><ctrl-v> "zP`m

Save a read-only file.  Careful, it changes the permissions. When
done, it changes them to read/write owner, read for everyone else. Note
that this might not be the same as the original permissions.
map K :!chmod 666 %<ctrl-v><enter>:w!<ctrl-v><enter><ctrl-v><enter>
:!chmod 644 %<ctrl-v><enter>

vi status line (sort of...) [Note:  It's slow...]
map <ctrl-v><up-arrow> k<ctrl-v><ctrl-g>
map <ctrl-v><down-arrow> j<ctrl-v><ctrl-g>
map k k<ctrl-v><ctrl-g>
map j j<ctrl-v><ctrl-g>
map <ctrl-v><ctrl-f> <ctrl-v><ctrl-f><ctrl-v><ctrl-g>
map <ctrl-v><ctrl-b> <ctrl-v><ctrl-b><ctrl-v><ctrl-g>
map H H<ctrl-v><ctrl-g>
map M M<ctrl-v><ctrl-g>
map L L<ctrl-v><ctrl-g>
map G G<ctrl-v><ctrl-g>
map <ctrl-v><ctrl-u> <ctrl-v><ctrl-u><ctrl-v><ctrl-g>
map <ctrl-v><ctrl-d> <ctrl-v><ctrl-d><ctrl-v><ctrl-g>

center a line
map = 080i <ctrl-v><esc>$78hd0^D:s/  / /g<ctrl-v><enter>$p

redefine tab to insert 5 spaces instead of a tab marker
map! <ctrl-v><ctrl-i> <space><space><space><space><space>

switch current and last line (repeat to reverse a file)
map v Gdd''Pj

yank until end of line, run it in a shell and read in the result
map v y$o<ctrl-v><esc>pI:r!<ctrl-v><esc>"add@a

allow vi to backspace over text that was inserted in a previous
insert mode
map! <ctrl-v><ctrl-?> $<ctrl-v><esc>Xs
map! <ctrl-v><ctrl-h> $<ctrl-v><esc>Xs

print the document to the default printer (for BSD replace lp with lpr).
map v 1G!Glp<ctrl-v><enter>u

set # to toggle line numbers on and off:
map \o# o:se nu<ctrl-v><enter>:se nonu<ctrl-v><esc>-:map \o# "wp<ctrl-v><enter>
map \d# "w2dd
map \x# "xdd@x"xpk
map # ma3L\o#\x#\d#`a:<ctrl-v><enter>

Quote the current paragraph with '>'s.
map Z> mc{jma}kmb:'a,'bs/^ /> /<ctrl-v><enter>'c

Allow <ctrl-z> to suspend processes within insert mode
map! <ctrl-v><ctrl-z> <ctrl-v<esc>:stop<ctrl-v><enter>
Make all tabs spaces
map! <ctrl-v><ctrl-v><ctrl-v><ctrl-i> <ctrl-v><ctrl-v><space>

Replace all tabs with the proper amount of spaces for the given
tabstop. Removing the last two character (4<enter>) will allow you to
specify the tabstop: #t4<enter>
map #t 1G!Gpr -t -e4<ctrl-v><enter>
map #T !}pr -t -e4<ctrl-v><enter>}

Insert a ruler above the current line
map #r O<ctrl-v><esc>i....+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8<ctrl-v><esc>

This is a macro that redefines itself: (more for heuristic reasons
than anything else) It inserts foo the first time it is run, and bar
all subsequent times.
map K ifoo<ctrl-v><esc>:map K ibar<ctrl-v><ctrl-v><ctrl-v><esc><ctrl-v><enter>

This makes end notes. It will insert a [#] at the current location
and put a [#] at the bottom of the document and let you type there.
Hitting `a will take you back to the original location once you are
done with your end note. [#] will be the number of the end note, not
the literal # character. (Pretty crazy, huh?)
map K ma1GO[0]<ctrl-v><esc>G$?\[[0-9]*\]<ctrl-v><enter>lyt]`aa<ctrl-v><enter><ctrl-v><esc>O<ctrl-v><esc>pI:r!echo '1 <ctrl-v><esc>A + p' <ctrl-v><ctrl-v>| dc<ctrl-v><ctrl-v><ctrl-v><ctrl-v><ctrl-v><ctrl-v><ctrl-v><enter><ctrl-v><esc>0"yD@y0i[<ctrl-v><esc>A]<ctrl-v><esc>kkJJJmb1Gdd`bF[yf]Go<ctrl-v><esc>pA

8.0 - Setting up .exrc file

Any commands that can be used in command input mode ( : commands),
may be used in a .exrc, which will load automatically whenever you
start vi.  In addition, the source command (so), abbreviations (ab),
and macros may be used.  There may not be any blank lines in your
.exrc.  A " in the first column may be used to tell vi that what
follows is a comment.

8.1 - Sample .exrc file

This .exrc file is a real one.  Mine.  Because of that, it doesn't
set as many options as one might wish it did to get a good idea of what
may be used.  However, it should get the basic idea down, and it is
quite straightforward.

First, note that you do not need to specify the :, it is assumed.
