Indent ¶

in order to auto indent a section (a selection of rows for example) we can use:

>: Indent more

<: Indent less

=: Autoindent
:set sw=2: Change indent to 2 spaces

Re-indent a whole file ¶

ggG=: Wich means: go to the top, select to the end of file, auto indent.

vimrc ¶

.vimrc:

autocmd FileType python set omnifunc=pythoncomplete#Complete
autocmd FileType javascript set omnifunc=javascriptcomplete#CompleteJS

  " (happens when dropping a file on gvim).

Auto indent ¶

In order to set C-style auto indenting with a 4 spaces TABs:

" Smartindent with 4 spaces
set cindent
set tabstop=4
set shiftwidth=4
set expandtab

To turn all tabs in spaces: :%retab

Fast set-up: set expandtab ts=4 sw=4 ai

In previous .vimrc there was filetype plugin indent on wich defins indent as well on a file type basis (but no TAB width).

Movements ¶

H   move to top of screen
M   move to middle of screen
L   move to bottom of screen

Scroll page ¶

SHIFT g: jumps to end of file.
gg: jumps to the beginning of file.
``: jumps to previous location

Page movements ¶

CTR d: Scrolls down half page of text
CTR b: Scrolls up an entire page
CTR e: Scrolls down a single line
CTR y: Scrolls up a single line

In page movements ¶

z ENTER: Actual line goes on top

or zz
Actual line goes to middle of the screen

z-: Actual line to bottom of the screen

Marks ¶

ma set mark a at current cursor location
‘a jump to line of mark a (first non-blank character in line)
`a jump to position (line and column) of mark a
d’a delete from current line to line of mark a
d`a delete from current cursor position to position of mark a
c’a change text from current line to line of mark a
y`a yank text to unnamed buffer from cursor to position of mark a
:marks list all the current marks
:marks aB list marks a, B

Registers ¶

Previous yanked / deleted buffers are available with : :registers . This can be re-used with es:

"2p: Paste not last (1) but previous buffer.

It is possible to create custom bufferrs: after making a selection: "ayy copies the content of a line and assign it to the buffere "a .

Comments ¶

For fast one / multiple line comment use: http://www.vim.org/scripts/script.php?script_id=1528

[CTR] + c: Comment one or mole lines (visual)
[CTR] + x: Un-Comment one or mole lines (visual)

When typing an html document, you can automatically close html tags using omni completion. For example, you may type <li>example</ then press Ctrl-x Ctrl-o to automatically finish typing the tag so the text reads <li>example</li>.

With the following abbreviation in your vimrc, you can simplify this process:

:iabbrev </ </<C-X><C-O>

With this abbreviation, you can simply type </ then press Space to automatically complete the tag.

C++ formatting ¶

apt-get install astyle
:%!astyle   (inside vim)

in .vimrc:
map <F4>    :%!astyle<CR>

Ctags ¶

ctags -R .
Jumping to a tag: You can position the cursor over a tag name and then press Ctrl-]
Returning after a tag jump: You can press Ctrl-t.
Ctrl+W Ctrl+] - Open the definition in a horizontal split

gd ¶

ca”: cambia attorno ai double quotes

Funziona con w , tags t , braces {, brackets [, …

Increment ¶

[CTR]a: su un numero

Macro ¶

qa: registra una macro in a
@a: riesegue quella macro

z=          suggest
zg          add

Powerline ¶

Debian way ¶

installare:

apt-get install vim-nox powerline python3-powerline fonts-powerline

.tmux.conf

source "/usr/share/powerline/bindings/tmux/powerline.conf"

.bashrc

# powerline
powerline-daemon -q
POWERLINE_BASH_CONTINUATION=1
POWERLINE_BASH_SELECT=1
. /usr/share/powerline/bindings/bash/powerline.sh

.vimrc:

Per Vim non ci sono le estensioni!
Bisogna installare tutto manualmente :(

~/.ipython/profile_default/ipython_config.py

c = get_config()
c.InteractiveShellApp.extensions = [
    'powerline.bindings.ipython.post_0_11'
]

Manual install ¶

Install python mode:

git clone --depth 1 https://github.com/klen/python-mode.git
cp -R python-mode/* ~/.vim

    Then rebuild helptags in vim:

:helptags ~/.vim/doc/

Installare powerline per pip3 / python 3 e controllare il path:

apt-get install python3-pip
pip3 install powerline-status

In .vimrc:

" powerline
set rtp+=/usr/local/lib/python3.5/dist-packages/powerline/bindings/vim/
set laststatus=2
set t_Co=256
let g:Powerline_symbols = 'fancy'

" flake skip errors reports
let g:pymode_lint_ignore="E221,E251"

Fonts per powerline, l’install fa fatto per ogni utente:

git clone --depth 1 https://github.com/powerline/fonts
fonts/install.sh

oppure:

apt-get install fonts-powerline

Serve vim con il supporto di python3, tipicamente vim-nox:

apt-get install vim-nox
vim --version | grep +python
