Invocation

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)

Simple 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/src/tags
TlistAddFiles *.cpp
TlistAddFiles *.h
TrinityToggleTagList
nmap <A-Up> <C-W><Left>[[zz<CR>`"
nmap <A-Down> <C-W><Left>]]zz<CR>`"

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.

<       shift left
zf      define a fold

:s/search/replace/g             Search & replace - current line

:echo &textwidth                Show value of a Vim option

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 [4]. 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 option paste).
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:
http://vim.wikia.com/wiki/Best_Vim_Tips
  • 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 ([5])
  • 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 [6]).
  • (from [7]), 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
