Additionally:

• vim (or nvim)
• micro
• git
• zsh

• bottom (top alternative, https://github.com/ClementTsang/bottom#debianubuntu )

On standalones:

• openvpn
• ssh server
• autosuspend (maybe)

On mac

Zsh

• Change to zsh with chsh
• Install oh-my-zsh with
  sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
• Ensure LC_CTYPE (or LANG) is set to en_US.UTF-8
• Install zsh-autosuggestions:
  git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
• Install zsh-syntax-highlighting
  git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

.zshrc (and oh-my-zsh configuration)

# Current favorite theme
ZSH_THEME="fishy-asdf"

# Update oh-my-zsh when it's time
zstyle ':omz:update' mode reminder

# YMD format in history command
HIST_STAMPS="yyyy-mm-dd"

# Plugins
plugins=(
        git
        asdf
        awsume
        zsh-asdf-prompt
        zsh-autosuggestions
        zsh-syntax-highlighting
        )

# Alias for python if Debian doesn't set it up
alias python=python3

Other interesting plugins: python, sdk, sbt, node, ssh-agent

Environment

Can go in ~/.zshenv or ~/.zshrc

# Editor (vi when in VS Code terminal, but micro otherwise)
if [[ $TERM_PROGRAM ]]; then
        export VISUAL="vim"
else
        export VISUAL="micro"
fi
export EDITOR="$VISUAL"

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

oh-my-zsh

vim

Enhanced defaults at https://github.com/tpope/vim-sensible

micro editor

In ~/.config/micro/settings.json:

{
    "clipboard": "terminal"
}

Git

In ~/.gitconfig:

[user]
        name = Thomas Petersen
        email = [e-mail]
[pull]
        ff = only

or alternately rebase = false under pull

Python

Install pipx into ~/.local/ with

python3 -m pip install --user pipx
python3 -m pipx ensurepath

Now install pipenv with
pipx install pipenv

The oh-my-zsh plugin for python looks decent.

asdf

• Download from git: https://asdf-vm.com/guide/getting-started.html#_2-download-asdf
• Enabling oh-my-zsh plugin will ensure paths etc are set up in zsh. Use https://asdf-vm.com/guide/getting-started.html#_3-install-asdf to cover more shells
• Install python plugin with
  asdf plugin add python
• Install e.g. v3.8.12 with
  asdf install python 3.8.12
• In ~/.tool-versions add

python system
nodejs system

• Add .tool-versions file to development projects as needed

asdf-prompt

Install asdf-prompt plugin for oh-my-zsh from https://github.com/CurryEleison/zsh-asdf-prompt

AWS

AWS cli v2 install from https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html . Do not use the pip package. To install as a userland application download, unpack and then install with:
./aws/install --install-dir $HOME/.local/aws --bin-dir $HOME/.local/bin

Optionally set default region in ~/.zshenv with
export AWS_DEFAULT_REGION=eu-west-1

awsume

Install with
pipx install awsume

oh-my-zsh plugin at https://github.com/Sordie/AWSume

sudo

Can specify visudo editor with
Defaults editor=/usr/bin/vim

Specify a group sudo with
%sudo ALL=(ALL:ALL) ALL

Place overrides at end of sudoers file:

# no password to suspend machine
tpetersen       ALL=(ALL) NOPASSWD: /usr/bin/systemctl suspend
# No password to start and stop VPN
tpetersen       ALL=(ALL) NOPASSWD: /usr/bin/systemctl start openvpn-client@<VPNCONFIG>
tpetersen       ALL=(ALL) NOPASSWD: /usr/bin/systemctl stop openvpn-client@<VPNCONFIG>

docker

Install programs at https://docs.docker.com/engine/install/debian/

Configure with https://docs.docker.com/engine/install/linux-postinstall/

jvm

Have used SDKMAN from https://sdkman.io/ with good results. asdf does have plugins, but I haven't been experimenting much.

There is an asdf plugin at https://github.com/halcyon/asdf-java which seems maintained as well as a scala plugin.

node

node is often best managed from asdf

Some nice environment variables to set up for node:

NPM_PACKAGES="${HOME}/.npm-packages"

export PATH="$PATH:$NPM_PACKAGES/bin"

# Preserve MANPATH if you already defined it somewhere in your config.
# Otherwise, fall back to `manpath` so we can inherit from `/etc/manpath`.
export MANPATH="${MANPATH-$(manpath)}:$NPM_PACKAGES/share/man"

R

Use asdf or https://cran.r-project.org/bin/linux/debian/ to install base.

To stop nagging about saving workspace:
alias R='R --no-save'

R Packages

You will need libcurl. E.g.
sudo apt install libcurl4-openssl-dev

For the Visual studio plugin you probably want radian:
pipx install radian

The following are worth installing right away. Take them one at a time since installation errors are common.

# For Visual Studio Code plugin
install.packages("languageserver")
install.packages("httpgd")
# For actual analysis :)
install.packages("tidyverse")

Visual Studio Code R plugin

The good plugin is at https://marketplace.visualstudio.com/items?itemName=Ikuyadeu.r . Once installed you can set up keyboard shortcuts: https://github.com/REditorSupport/vscode-R/wiki/Keyboard-shortcuts and enable httpgd:
echo "options(vsc.use_httpgd = TRUE)" >> ~/.Rprofile

R Markdown

Needs pandoc and a copy of $LaTeX$. https://alexd106.github.io/intro2R/install_rmarkdown.html . (I have not tried to get that going yet.)

.NET

Installation: https://learn.microsoft.com/en-us/dotnet/core/install/linux-debian

Fun and Optionalities

Syntax Highlighting with less

With highlight (Best option)

sudo apt install highlight
export LESS=-FMRXis
export LESSOPEN='| command highlight --force -O truecolor --style aiseered "%s"'

You can also just go export LESS=" -R " which I think is already the default in Debian.

There is also a nice more elaborate solution at https://superuser.com/a/1332042

Ctrl+D in PowerShell

To exit with Ctrl+D from PowerShell do

notepad $profile

and in the resulting editor put in the lines

Set-PSReadlineKeyHandler -Key ctrl+d -Function ViExit
Set-PSReadLineKeyHandler -Key "Ctrl+f" -Function ForwardWord

The latter helps with fish-style completions of greyed completions.
