VI commands

VI SHIT

VIM defaults are in ~/.vimrc

:set noai

Sets auto indent

:set nocindent

sets autoindenting for braces and stuff

:set paste

is good to paste stuff in the format it was copied

(good to put these off for pasting stuff from other config files)

<shift+v> visual line select
<alt+v> visual select point to point
<ctrl+b> visual block select
Y = yank (copy)
d = (cut)
P = paste after


:start-line,end-linew /tmp/filename

write lines to /tmp/filename

:.,$s/bla/BLA/g

replace bla to BLA from current line to last line in doc.


lines: . = current line, $ = last line

:.,100 d    = delete from current line to line 100 (, = seperator)

in the editor, doing
226dd
will delete the next 226 lines from the cursor

:!ls

runs 'ls'

:r!ls

runs ls and puts the output in the open buffer

:set number
:set nonumber

puts the line numbering on or off

:set textwidth=0
puts the max textwidth off for wrapping

Find and replace goes with
:%s/findme/replaceme/ 
for the first instance and
:%s/findme/replaceme/g
for every instance in the file (g)

To replace every ; in a file with a new line use

:%s/;/<ctrl-v> <enter>(will turn into ^M)/g

The / charachter can be replaced with any other character and special characters such as /,",', etc can be escaped.
EG to replace every / in a file with a new line use
:%s/\//\r/g


To get rid of "^M" (MSDOS carriage returns) in a file or to put them in
press control+V and then type M (or press the enter key).
You can find and replace with this too.

Some usefull regular expressions to know (and use in replacements) are
\n - newline (for windows files)
\r - return (for unix files)
\s - for spaces
use only \r to get stuff onto next lines, \n creates the ^@ char, and I'm not sure what that does yet
