Some videos that illustrates those plugins:
- Top Vim Plugins (YouTube), showing Surround, SnipMate, TComment, MRU, FuzzyFinder, NerdTree, MatchIt
Plugins (uninstalled)
- easytags.vim : Automated tag file generation and syntax highlighting of tags in Vim
- Replaced by AutoTag — syntax highlighting of tags is limited to c files; moreover AutoTag has a clever way to look for the tags file in project hierarchy.
- minibufexpl.vim : Elegant buffer explorer - takes very little screen space
- No real tab support. Seems to interfere with trinity plugin. Interesting key bindings inside though. To reassess...
Invocation
vi -p file1.txt file2.txt # Open each file in a different tab
vi -t tagname # Open file and move cursor at specified tag (requires ctags)
view file.txt # View file in vim, with syntax highlighting... (read-only)
vimdiff file1.txt file2.txt # View differences in vim
Simple C/C++ IDE using plugin TagList
Thanks to plugin TagList, it is possible to turn Vim into a simple yet efficient development IDE. The basic idea is to use the TagList window as a simple file explorer. We use a session file to add all files in the project to the TagList window. Also we define 2 mappings to ease navigation between files.
Here an example session file Session.vim:
set tags=/win/d/projects/noekeon64/nk_fasttrails/tags
TlistAddFiles src/*.cpp
TlistAddFiles src/*.h
TrinityToggleTagList
nmap <A-Up> <C-W><Left>[[zz<CR>`"
nmap <A-Down> <C-W><Left>]]zz<CR>`"
Create the tag file:
ctags -R .
Then start the IDE session with:
gvim -S
Use the mappings A-Up / A-Down to switch the current window to the next/previous file. These mappings simply move and center the cursor in the TagList window to the previous/next file, open the file and put the cursor to its last position.
To build the project (assuming you have a valid Makefile in the project directory), just issue the command
:make
To easily navigate between the compilation errors, open the error window:
:cope
Keyboard & Mouse Shortcuts
- ! If keys HJKLM have been remapped to MHJKL, shortcut below must be changed accordingly !
- Mouse shortcuts requires
:set mouse=a
. - Customer shortcuts are underlined

Operator & motion
Operators in Vim acts
- on the current selection (visual mode like v, V or ^v) when there is such a selection,
- or must be followed by a motion indicating which part of the text must be modified.
Operators
|
The motion is either one of the motion key (like >% for shift right until match) or an operator motion (like diB for delete inner {} block). See :help operator.
Frequently-used operator motion
iw iW |
inner word inner WORD |
aw aW |
a word a WORD |
i[ ib i( |
inner [] block inner () block |
a[ ab a( |
a [] block a () block |
i" i' |
inner "" string inner '' string |
a" a' |
a "" string a '' string |
Commands
" Search & replace - current line
:s/search/replace/g
" Search & replace - global scope
:%s/search/replace/g
" Set Vim option (here textwidth)
:set {option}=70
" Show value of {option}
:echo &{option}
:set {option}?
" Search / replace in all opened buffers
:bufdo %s/pattern/substitution/ge | update
Miscellaneous Tips and Tricks
- Inserting only a single character (http://vim.wikia.com/wiki/Insert_a_single_character).
- Macro
- qq to start recording a macro q. End macro with q again.
- @q to replay macro, followed by . to replay it again.
- Visual Block
- Ctrl-v to start VISUAL BLOCK mode.
- Shift-I to insert some text at the start of each line of selected block.
- wrap-around
- Set option whichwrap or ww that allows specified keys that move the cursor left/right to move to the previous/next line when the cursor is on the first/last character in the line.
- In Vim, <space> and <backspace> are set to wrap-around by default.
- Read-only viewer (with syntax highlighting):
$ vi -R sensitive_file
$ view sensitive_file
- Retab
- To convert tabs in current file to current tab settings, use command
:retab
[2]. For instance to convert tabs into space
:set expandtab :retab
- View differences in vim
vimdiff file1.txt file2.txt
- Interaction with X Clipboard
- vim can use the X clipboard if it has been compiled with the clipboard feature (run
vim --version
and see if you have +clipboard in the output). In that case, yanking to the+
register, or simply selecting with the mouse, will actually copy in the X clipboard, hence allowing other applications, or even other instances of vim to exchange text snippets. Also, it will ease the copy-paste of indented text, since in that case, vim will first disable autoindentation before pasting the text (see optionpaste
). - On system like Ubuntu, you need to install an instance of gvim (like package vim-gnome or vim-gtk) to have feature
+clipboard
turned on (i.e. installing package vim is not enough). - When
set mouse=a
, use shift-mouse to still use the xterm copy/paste (see mouse-using).
set incsearch
, moves cursor as search pattern is typed. Ctrl-L to type letter under cursor, Ctrl-R Ctrl-W to type current word.- References:
- type
:help ctrl<C-D>
, to get a list of all ctrl sequence. Type <C-D> in command line for auto-completion. - Support 256 colors in gnome-terminal: add
set t_Co=256
in ~/.vimrc ([3]) - Use
:make
and:grep
instead of:!make
or:!grep
. Then use:cwin
or:copen
to view the results of either make or grep in a coloured list (from [4]). - (from [5]), The
:g
command is useful to apply a command to all lines matching a search.
" delete all lines matching pattern
:g/pattern/d
" delete all lines *NOT* matching pattern (:v same as :g!)
:g!/pattern/d
:v/pattern/d
- Write the following in files ~/.vim/after/syntax/c.vim and ~/.vim/after/syntax/cpp.vim (or symlink) to highlight C/++ delimiters (see [6]):
syn match cDelimiter "[&\.!^,;:<>=|+%*-]"
syn match cParenDelimiter "[][(){}]"
hi def link cDelimiter Delimiter
hi def link cParenDelimiter Delimiter
- Replace a word with yanked text (see tip [7])
yiw " Yank word under cursor "
... " Move to next word "
viwp " Replace current word with yanked text. "
...
viwp

To Do
- Done Find a way to prevent vim to mess up with my register when deleting text.
- Auto-complete, use cursor keys instead of up/down to search in the drop down list.
- Look at Virtual-edit (see http://vim.wikia.com/wiki/Add_trailing_blanks_to_lines_for_easy_visual_blocks)
