Set up SSH for remote development (VS2017, CLion, VSCode)

Run wsl_ssh_setup.sh (source code below):

wget https://gist.githubusercontent.com/mloskot/aa24d374590d001c9fc8548fcf8c25e6/raw/ecb80e971130a8c8b3a7cd1fdde31b004751bdf0/wsl_ssh_setup.sh && sudo bash wsl_ssh_setup.sh

Powerline

WARNING Powerline is bloody slow in large git trees eg. Boost repository

• Install Powerline fonts on Windows

git clone https://github.com/powerline/fonts.git  
cd fonts  
./install.ps1

Go to WSL Bash command prompt, Properties and change font to "DejaVu Sans Mono for Powerline".

• Install Powerline in WSL

sudo apt-get install build-essential git python-pip

cd ~  
mkdir src  
cd src  
git clone https://github.com/banga/powerline-shell.git

cd ~/src/powerline-shell  
cat config.py.dist > config.py  
./install.py

• Configure Powerline in WSL

vim .bashrc
# Copy & paste this at the end of the .bashrc
function _update_ps1() {  
    PS1="$(~/src/powerline-shell/powerline-shell.py $? 2> /dev/null)"
}

if [ "$TERM" != "linux" ]; then  
    PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"
fi  

Clion
