Environment Setup

This repository contains various scripts and configuration that I use in my various environments - private or work, bare metal or virtual machine. I created this collection since I'm usally working with various virtual machine and I want to have my environment set as fast as possible while providing the same user experience on each of them. Everything is done using only Bash since it's the common base of every Unix install. Of course it would be fancier using e.g. Python's full capabilities.

Set up Unix Environment

The script ./unix/setup.sh provides a simple but clear entry point to setup any Unix environment (currently arch and ubuntu is supported). Everything can be set up by executing the following command - an internet connection is required since the script will get other scripts and configurations from this repository.

bash -c "bash <(curl https://raw.githubusercontent.com/TumbleOwlee/env-setup/main/Unix/setup.sh 2>/dev/null)"

If you are behind a proxy, keep in mind to set http_proxy and https_proxy accordingly. Currently no offline installation is supported. The command only uses bash -c calling bash because the command should work by copy&paste in any shell you are currently using.

In case you cloned the repository and want to execute the script ./Unix/setup.sh directly using only local files, just use the following command instead.

DEBUG=y ./Unix/setup.sh

This will source the other scripts instead of using curl to retrieve the files from the repository on Github.

Installed Applications

While executing you can choose the parts you like to install and skip any you don't need. Currently the following parts are available to be installed:

Alacritty
Fish Shell
Tmux
Neovim
- NerdFonts
- Neovim Lua LSP
- Neovim Python LSP
Docker
Rust Environment
- Rustup
- Rust-Src
- Rust-Analyzer
- Neovim Rust LSP
C++ Environment
- Clang
- GCC
- CMake
- Neovim Clang LSP
Bioinformatics Environment
- snakemake

If available the configurations from this repository are also installed for the applications respectively. In case of Neovim, the configuration is taken from here. I will add additional parts as time goes on and my demands change.

Set up Windows Environment

Since I'm mainly developing on Unix based operating systems, this repository doesn't contain any script to setup a full environment on a Windows host. Instead it contains scripts to provide helper functions to simplify the interaction with Unix systems.

To get the provided helper function in your PowerShell environment, just install the files in ./windows/Scripts into %USERPROFILE%\Scripts and ./windows/Documents/PowerShell into %USERPROFILE%\Documents\PowerShell.

mkdir $home\Scripts

# Wrapper to provide `Connect-SSH` in PowerShell for easy SSH connection
curl https://raw.githubusercontent.com/TumbleOwlee/env-setup/main/Windows/Scripts/connect.py -o $home\Scripts\connect.py

# Install PowerShell profile that provides the aliases for all functions
curl https://raw.githubusercontent.com/TumbleOwlee/env-setup/main/Windows/Documents/WindowsPowerShell/profile.ps1 -o $home\Documents\WindowsPowerShell\profile.ps1

If your Windows system has some more restriction in place (e.g. your home directory is on a network drive), the PowerShell script may not load at all. A quick and dirty solution for that is to place the profile.ps1 into C:\Windows\System32\WindowsPowerShell\v1.0 instead of %USERPROFILE%\Documents\PowerShell.

Additionally it is advised to install the FiraCode Nerd Font if you have installed alacritty and use the provided configuration. It's also helpful in case you are using the provided neovim configuration file, since it requires the patched font to display additional icons.

Using Bash

The provided setup installs fish as the default shell. But if you're using other hosts - where you are unable to install/use fish - you can get the same shell prompt by adding the following code into your ~/.bashrc.

colorize_exit_code() {
        exit_code="$1"
        local red=$(tput setaf 1)
        local green=$(tput setaf 2)
        local reset=$(tput sgr0)
        if [ "$exit_code" == "0" ] || [ "$exit_code" == "" ]; then
                printf '\001%s\002[0]\001%s\002' "$green" "$reset"
        else
                printf '\001%s\002[%s]\001%s\002' "$red" "$exit_code" "$reset"
        fi
}

# Most likely such an if-else block will already be present in your .bashrc. Just replace it with this.
if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}(\[\033[0;33m\]\h\[\033[m\]|\[\033[0;34m\]\u\[\033[m\]|\[\033[0;33m\]\w\[\033[m\])$(colorize_exit_code $?)> '
else
    PS1='${debian_chroot:+($debian_chroot)}(\h|\u|\w)[$?]> '
