Install base16-vim

BASE16_SHELL="$HOME/.config/base16-shell/"
[ "$TERM_PROGRAM" != "vscode" ] &&

sudo make install

or 

sudo checkinstall 

And then go to ~/.vim_runtime/my_plugins:

git clone https://github.com/Valloric/YouCompleteMe.git
cd YouCompleteMe
git submodule update --init --recursive
python3 install.py --all

or 

python3 install.py --ts-completer --rust-completer # for TypeScript & Rust only

• JavaScript and TypeScript support: install Node.js and npm, navigate to YouCompleteMe/third_party/ycmd and run npm install -g --prefix third_party/tsserver typescript.

• Keep an eye on the version of typescript inside YouCompleteMe/third_party/ycmd/third_party/tsserver

My Tmux & Vim configuration

I'm climbing the Vim world. The most frustrated thing until now is to make vim looks nice. However I'm getting there :)

Tmux must be configured & start differently

• please refer to .tmux.conf file to see the screen-256color config
• start tmux using : tmux -2 to force it to run in 256 mode

Make Tmux bar look nice

Please see my .tmux.conf file

Improve fonts rendering with Infinality

To install on Ubuntu:

$ sudo add-apt-repository ppa:no1wantdthisname/ppa
$ sudo apt-get update
$ sudo apt-get install  fontconfig-infinality freetype

Run the following commands to choose and apply a font configuration:

$ sudo /etc/fonts/infinality/infctl.sh setstyle

Use vimrc

https://github.com/amix/vimrc

Vim colorscheme must be aligned with your Terminator (iTerm) profile

I used SpaceGray (https://github.com/ajh17/Spacegray.vim)

So, Terminal color profile has to be set to Spacegray And colorscheme in .vimrc must be set to Spacegray, too

Plugins:

Using Ag/Ack

http://conqueringthecommandline.com/book/ack_ag#cid17

# search in folder
ag DHH guides/

# regular expression search
ag readme$

# literal expression search
# -Q flag. This will search for the exact pattern
ag -Q .rb railties/CHANGELOG.md
 
# Listing files
ag DHH -l

# Case Insensitive Searches (-i)
ag readme -l -i

# Scoping to Files (-G)
ag readme -l -i -G ec$

# Ignore Paths
# The –ignore-dir Flag
ag readme -l --ignore-dir=railties/lib

# We can easily chain multiple –ignore-dir calls together to filter our results further
ag readme -l --ignore-dir=railties/lib --ignore-dir=guides/code

# Despite its name, the –ignore-dir flag will also let us filter out particular files, not just directories
ag readme -l --ignore-dir="*.rb"

Python

You might want to comment out bellow lines if you want to have tab switching using Leader + 1, Leader + 2 inside a .py file:

// inside ~/.vim_runtime/vimrcs/filetypes.vim

au FileType python inoremap <buffer> $f # --- <esc>a
" au FileType python map <buffer> <leader>1 /class
" au FileType python map <buffer> <leader>2 /def
au FileType python map <buffer> <leader>C ?class

Ubuntu Natural scrolling

/usr/share/X11/xorg.conf.d/40-libinput.conf

Add there Option "NaturalScrolling" "True" like this:

For your mouse

# Match on all types of devices but joysticks
Section "InputClass"
        Identifier "libinput pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "NaturalScrolling" "True"
EndSection
