Vim + Windows

change menu and messages to us english

c:\Installed\Text\Vim\_vimrc

set langmenu=en_US.UTF-8    " sets the language of the menu (gvim)
language en                 " sets the language of the messages / ui (vim)
setlocal encoding=utf-8     " so you can get for example german umlauts

VIM + Linux

Install vim or you will only have a bad vi clone

 apt-get install vim gpm ctags vim-doc

Vi Shortcuts

pasting

If you paste formatted code, it will look ugly. Either use

set paste
... do stuff
set nopaste

Or use something like

set pastetoggle=<F2>

starting vim

vim -o *.php     open vim with a view for each found php file
vim -p *.php     open vim with one tab for each found php file
vim -u NONE      start vim without any plugins

recording

q <letter>        record the following
q                 stop recording
@<letter>         play the recording
<number>@<letter> play the recording <number> times

I use this for example to check files which have to be in a certain format. The '.' does only repeat the last command that did change something, so you need to do it different for move commands.

misc

:reg                 show registers, like copy buffers
:set paste/nopaste   allow to paste formatted source code
:set hls/nohls       highlight search matches
:set list            show special chars
:set et!             leave tabs alone
:set et              replace tabs with spaces depending on the tabstop value
:set tabstop=N

 ctrl-e/y        move screen one up/down
 zt/zb/z.        scroll current line to the top/bottom/center of the view
 gf              open file under cursor
 :split          new window
 :split <file>   new window with given file

 ctrl-w p        jump to last window
 ctrl-w f        open file under cursor in new window
 ctrl-w _        resize to max (like :res without parameter, that is an underscore)
 ctrl-w }        preview tag under cursor
 :tabnew         create a new tab
 ctrl-w gf       open new tab with file under cursor
 crtl-w T        move current split to new tab
 gt/gT           move to next/previous tab
 <n> gt          move to given tab, count starts with 1
 :tabc[lose]     close the current tab
 :tabo[nly]      close all other tabs
:res <lines>            resize window height
:vertical res <columns> resize window width

delete

 dw              delete until end of word
 d$              delete until end of line
 d/BLA           delete until BLA, example: d/>  delete until >, but do not delete the >


change

 guw             make the word lowercase
 gUw             make the word uppercase
 gu$             make lowercase until the end of line
 guu             line lowercase
 gUU             line upercase
 g~~             line change case
 g~w             word change case

Sessions

If you have some windows open and would like to return some day to this layout, just use

 :mksession! <filename>

for example

 :mksession! proj-1.vim

and when you later want to continue where you were, you either start vim like this

 vi -S proj-1.vim

or you use the following command being in vi

 :source proj-1.vim

You will have to watch yourself, so you are always in the correct directory. Here are two mappings which may help you:

 map <F5> <ESC> :mksession! quicksave.vim <Return>
 map <F9> <ESC> :source quicksave.vim <Return>

This gets interesting, when you later rename the quicksave.vim *and* change the mappings in the new .vim file to ones that load and save *that* .vim file. Example:

 mv quicksave.vim misc.vim
 map <F5> <ESC> :mksession! misc.vim <Return>
 map <F9> <ESC> :source misc.vim <Return>

That way you can save and load your current session with F5 and F9.

rename-quicksave.sh

#!/bin/bash

if [ "$1" = "--help" ] || [ $# -ne 1 ]; then
   echo rename-quicksave v 0.1
   echo This script will rename a quicksave.vim and change the string quicksave inside the .vim file.
   echo Syntax: $0 \<new name without .vim\>
   exit 1
fi

if [ ! -f quicksave.vim ]; then
   echo Error: File quicksave.vim has not been found in the current directory !
   pwd
   exit 2

CTags einrichten (exuberant-ctags)

http://weierophinney.net/matthew/archives/134-exuberant-ctags-with-PHP-in-Vim.html

First you have to make sure "exuberant ctags" is installed. Just call

ctags --version

to find out if it is installed. If not:

 apt-get install exuberant-ctags

create the tags:

#!/bin/bash
PROJECT_DIR=/home/user/work
TAG_DIR=/home/user/.tags
TAG_FILE=project.tags
TAG_FILE_TEMP=${TAG_FILE}.creating
          
mkdir -p $TAG_DIR
cd ${PROJECT_DIR}
ctags-exuberant -f $TAG_DIR/$TAG_FILE_TEMP \
    -h ".php" -R \
    --exclude="\.svn" \
    --exclude="\CVS" \
    --totals=yes \
    --languages=PHP \
    --tag-relative=yes \
    --PHP-kinds=+cf \
    --regex-PHP='/abstract class ([^ ]*)/\1/c/' \
    --regex-PHP='/interface ([^ ]*)/\1/c/' \
    --regex-PHP='/(public |static |abstract |protected |private )+function ([^ (]*)/\2/f/' \
    Project-*/*

mv ${TAG_DIR}/${TAG_FILE_TEMP} ${TAG_DIR}/${TAG_FILE}

ls -lh ${TAG_DIR}/${TAG_FILE}

You can use the created tag file on a normal system, where "exuberant-ctags" are not installed. It seems, you need the addon only to create the tags, but use the normal vi mechanism to use the tags. So the last line in the generator script could be like:

     scp ${TAG_DIR}/${TAG_FILE} <server>:$TAG_TARGET_DIR


Now you want to use the tags in every vi you start: ~/.exrc

  set tags=~/.tags/MyProjekt.tags

The documentation says to use

 ctrl-]        Jump to tag under cursor
 crtl-t        jump back

but in my systems I have to use

 ctrl-alt-]    jump to tag under cursor
 ctrl-alt-t    jump back
 ctrl-w ]      split tag under cursor into new window
 ctrl-(alt)-o  last position in jump stack or so (unsure)

FuzzyFinder

Either just use http://wiki.andreas-duffner.de/images/a/a3/Fuzzyfinder.vim or get the current version from http://www.vim.org/scripts/script.php?script_id=1984.

The current version does not work with vim 7.0.

in your .exrc

wildmode=list:longest
wildmenu
hidden
history=1000
cab ffb FuzzyFinderBuffer
cab ff FuzzyFinderFile
cab ffm FuzzyFinderMruFile
cab fft FuzzyFinderTag

in vim use

:Fuzzy<Tab>

to show all new commands. Above are shortcuts for some of them.

XML

  • get the script from xmledit
    • get the .vba file
  • edit the .vba file with vim
  •  :source %
  • installation done
  • edit your .exrc
"folding for xml
let g:xml_syntax_folding=1
au FileType xml setlocal foldmethod=syntax

"reformatting xml to look good
au FileType xml exe ":silent 1,$!xmllint --format --recover - 2>/dev/null"
au FileType xsd exe ":silent 1,$!xmllint --format --recover - 2>/dev/null"
au FileType wsdl exe ":silent 1,$!xmllint --format --recover - 2>/dev/null"


  • now you should have folds: zo zc etc...
  • open tags should be closed when you finish a tag with >
  • try >> for setting the cursor better

I am not using this below anymore. C++ tags are really all you need. The rest is nice to have or for show off. At least it seems so to me, because it did not help me to work faster.

from [1] I got how to get a better auto complete list for c++:

  • build your tags with the following command
ctags -R --sort=1 --c++-kinds=+p --fields=+iaS --extra=+q --language-force=C++ .
  • get omnicppcomplete from here omnicppcomplete
  • set the following in your .exrc or .vimrc file
