Since I reinstall Ubuntu several times, it would be better that I write a memo to record some process to set up
VIM in Ubuntu. This article reminds me some Plugins of
VIM that I usually used.
NERD_Tree
This is a Plugin that can show you the File Architecture.
Set Up
1. Download it from
here.
2. In your home directory, create a new "
.vim" directory (if you have no
VIM plugin yet).
3. Move everything in
NERD_Tree you just download to "
.vim" directory. And your "
.vim"
directory would look like:
doc nerdtree_plugin plugin syntax
4. Add the following line to "
.vimrc" file in your
$HOME directory, so that when you press
F2 in
your keyboard, the
NEARD_Tree will comes out.
nnoremap <silent> <F2> :NERDTree<CR>
Usage
1. When you want to see the file architecture, press
F2, and if you want to open a file in current
tab, just press
Enter when your cursor is on that file name.
2. If you want to open a file in a new tab, just hit
"Shift" + "t" when your cursor is on that file name.
3. You can use
"Ctrl" + "w" + "w" to switch between windows in
VIM.
4. Here is some commands (which already shiped with VIM) that can control the window or tabs:
(a)
":sp" + "FileName": Open a new file in the horizontal split window (so that you have two
window (the top and the bottom window). If you don't specified FileName,
VIM would open
the same file.
":vs" + "FileName": Likewise, open a new file in the vertical split windows.
(b)
"Ctrl" + "w" + "T": If you have splitted window, you can use this command to move the split
window to a new tab.
(c)
"Ctrl" + "w" + "+": If you have more than one horizontal split window, it would expand your
activate window (in which your cursor in) expanded by one more line (and shrink the others
by one line in the same time).
"Ctrl" + "w" + "-": The opposite of above.
(d)
"Ctrl" + "w" + "r": If you have more than one split windows, this will change the two
windows upside down.
(e)
":tabm +1": If you have more than one tabs, you can move the current tab to right by this
command.
":tabm -1": Likewise, you can use this command to move current tab to left.
TagList
You can use this plugin to see the class, functions, enums in the file.
Set Up
1. Download
TagList from
here.
2. Like
NERD_Tree, Unzip the file you just download, and move them to the "
.vim" directory. But
be careful not to replace the file that belong to
NERD_Tree. For example, after you set up the
NEARD_Tree or other plugins, you would have a "
doc" and "
plugin" directory in your "
.vim"
directory. Now move files inside "
plugin" (which is in the
TagList directory you just Unzip) to
the "
.vim/plugin". Other plugins of
VIM can be installed in the similar way.
Share Clipboard between VIM and Linux
Have you ever want to search all files to find a keyword (e.g. a function) been referenced?
One way to do this is to copy that keyword in
VIM and move to the other terminal and use the "grep" command. This can be done by use the mouse right-click and select "copy" in the
VIM and move to the other terminal and type "grep '" and use the mouse right-click and select "paste" to paste the keyword. And finally you search that keyword by "grep" command.
Isn't that kind of silly? And the reason you use
VIM is to avoid your hand switching between keyboard and the mouse...
Here is the solution: Make
VIM share clipboard with the system! Do do so, you must install
the
vim-gnome. The normal VIM fail to share its clipboard with system (if you want to see the detail, please see this article).
Fortunately, change from normal VIM to VIM-Gnome is easy. You just need to download it by:
sudo apt-get install vim-gnome
And it will read your original .vimrc setting without any further adjustment and must of the VIM plugins can be used directly. Now, add the following line in your .vimrc:
vnoremap <C-c> "+y
And when you in the command mode of VIM, select keyword by "v" and copy it by "Ctrl" + "c". Now move to the other terminal in the other tab by "Ctrl" + "Page Down" (or, use "Ctrl" + "Shift" + "t" to create a new terminal in the new tab), and now you can type "Ctrl" + "Shift" + "v" to paste the keyword!
Gtags
Do you want to find a plugin that can lead you to the definition of a function or has the ability to "find all reference of a variable or function"? Although the
Ctags and
Cscope support part of this, they don't support some C++ features (such as function overloading, class... etc). Therefore, that's why I recommend using
Gtags.
Set Up
1. Download it from
here.
2. You should also download the
ncurses that will be used by Gtags.
3. Build ncurses in the command line:
./configure
make
sudo make install
4. Build Gtags:
./configure
make
sudo make install
5. Copy Plugin to Vim:
cp /usr/local/share/gtags/gtags.vim $HOME/.vim/plugin
6. Add following line to your .vimrc:
nnoremap gd :GtagsCursor<CR>
map <C-n> :cn<CR>
map <C-p> :cp<CR>
nnoremap <C-f> :Gtags -r<CR><CR>
Thus, you can type
"g" + "d" on a function, the VIM will go to its definition, and
"Ctrl" + "f" to find all references (in this case, you can type
"Ctrl" + "p" to go to the previous reference, and type
"Ctrl" + "n" to go to the next reference).
QuickFix
QuickFix is built in VIM already, you can type ":copen" in the VIM command mode to open it (the QuickFix will reside in the bottom of the window). And when you want to compile your code, you can type ":make" in the VIM command mode. Then the code will start compiling, and show its compile info in the QuickFix window (as the first figure in this article).
Finally, here is my final .vimrc:
" Record the last preview line
au BufReadPost * if line("'\"") > 0|if line("'\"") <= line("$")|exe("norm '\"")|else|exe "norm $"|endif|endif
" highlight search
set hlsearch
" Quick leave by F12
nnoremap <silent> <F12> :q<CR>
" Refresh by F5
nnoremap <silent> <F5> :edit<CR>
" Plugins
nnoremap <silent> <F2> :NERDTree<CR>
nnoremap <silent> <F3> : Tlist<CR>
nnoremap <silent> <F4> :copen<CR>
" Copy
vnoremap <C-c> "+y
" Gtags
nnoremap gd :GtagsCursor<CR>
map <C-n> :cn<CR>
map <C-p> :cp<CR>
nnoremap <C-f> :Gtags -r<CR><CR>
