My zsh configuration. I'm using oh-my-zsh and place some overrides in ~/.zsh.

# Clone repo
git clone [email protected]:fiedl/dot-zsh ~/.zsh

This set of scripts won't touch your ~/.zshrc. Thus, add manually to your ~/.zshrc what you'd like:

# ~/.zshrc

# Use https://github.com/fiedl/dot-zsh as override
# for oh-my-zsh:
ZSH_CUSTOM="$HOME/.zsh/oh-my-zsh-customization"
ZSH="$HOME/.oh-my-zsh"

# Shell theme:
ZSH_THEME="fiedl"

# Auto-install ~/.oh-my-zsh if missing.
if [ ! -d $ZSH ]; then
  curl -L http://install.ohmyz.sh | sh
fi

# Auto-install ~/.zsh if missing.
if [ ! -d ~/.zsh ]; then
  git clone [email protected]:fiedl/dot-zsh.git ~/.zsh
fi

# Auto-updating ~/.oh-my-zsh as well as ~/.zsh
# requires to use another upgrade script.
# Therefore, deactivate the oh-my-zsh-only one.
# The rest is done by the `auto-update` plugin.
export DISABLE_AUTO_UPDATE="true"
export DISABLE_UPDATE_PROMPT="false"
export UPDATE_ZSH_DAYS=1

# choose oh-my-zsh plugins
plugins=(git bundler editor auto-update highlight fiedl icecube gnuplot install plattform latex powerlevel lcars)
source $ZSH/oh-my-zsh.sh

Then, start a new terminal. Done!

• When starting a terminal, oh-my-zsh will ask you to perform an upgrade, regularly. This will also update ~/.zsh.
• Or, run: zsh-update.
• Or, pull changes manually: cd $HOME/.zsh; git pull

# basic packages (arch linux only)
sudo pacman -S zsh emacs-nox htop ruby

# Install oh-my-zsh
sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

# Clone repo
git clone https://github.com/fiedl/dot-zsh ~/.zsh

# MANUALLY: copy required content from above into ~/.zshrc

# Start a new shell
zsh

# Start an auto-update
zsh-update

These commands help to sync the zsh configuration up and down. Through the oh-my-zsh auto update process, the repo is down-synced automatically. This is prevented by uncommited changes in ~/.zsh.

Quickly commit and push local changes:

zsh-push

If needed, with commit message:

zsh-push I added cool stuff ...

Get latest changes by running one of these:

zsh-pull
zsh-update

zsh-push will update the documentation in the README automatically. But it may be run manually, e.g. before committing manually.

zsh-update-documentation

To edit the plugin "welcome", just type:

zsh-plugin welcome
plugin welcome

This script hooks into the update process of oh-my-zsh and also updates ~/.zsh as well as some other things like homebrew.

To update manually, run:

zsh-update

This plugin makes use of zsh-hooks to allow other plugins to hook into the update process.

When writing a plugin, hook the functions to execute when updating into the process, like this:

foo_plugin_update() {
  # stuff executed by this plugin when
  # the update process is run.
}

hooks-add-hook zsh_update foo_plugin_update

Or, short:

hook zsh_update foo_plugin_update

Or, shorter:

on_update foo_plugin_update

Quickly start a text editor:

e
e .
e ~/.zshrc

If textmate (mate) is installed, it will be used as editor. Otherwise, emacs -nw (in the terminal, not as window). Otherwise, vim.

Aliases also work with sudo. This trick is from https://wiki.archlinux.org/index.php/Sudo#Passing_aliases.

Why? From the alias section in the bash manpage (http://serverfault.com/a/178956/167331):

A trailing space in value causes the next word to be checked for alias substitution when the alias is expanded.

These helpers are useful to find definitions in code or quickly grep for expressions.

def current_user
g class User

Quickly find a file within the current directory.

f user
f user |count

This uses friendly find (ffind), which needs to be installed. Mac: brew install ffind.

Find files on the NAS by:

nas-find Keith Jarrett
nf Keith Jarrett

My NAS has a cron job to create a file index at /share/Sebastian/.find.txt. In the work machine's file system, this is /Volumes/Sebastian/.find.txt. The above commands just grep in that file.

# crontab -e
0 2 * * * cd /share/Sebastian; /usr/bin/find ./ |sed -e 's/\.\//\/Volumes\/Sebastian\//g' > .find.tmp; /bin/rm .find.txt; /bin/mv .find.tmp .find.txt

Tail a file and follow it, even if the file is deleted and re-created.

tailf filename

This needs the gnu verion of tail. Install it with brew install coreutils.

Move multiple files with wildcards using multimove.

mmv foo-*.txt foo/*.md

Display the matrix. This requires brew install cmatrix.

matrix

ka vlc

service restart elasticsearch

Will be the same as:

brew services restart elasticsearch

Use gnuplot to plot something and display it right inside the terminal using imgcat.

Examples:

plot "sin(x)"
cat data.txt |plot

To select a command from the history to repeat, type the beginning and press the up key.

ssh<up>
# =>  ssh mccoy

This makes them also work in the terminal. I've taken this from http://zshwiki.org/home/zle/bindkeys.

When you type, the zsh checks whether the command in known. If so, it's highlighted.

I've taken this from https://github.com/zsh-users/zsh-syntax-highlighting and got the idea from https://github.com/idk/moo-skel.

On the icecube machine in zeuthen, there's I3_PORTS installed. Make some shortcuts:

ice-port
ice-cmake
clsim-make
icesim      # runs the env-shell

A great way to document console output is to run a bash kernel inside a jupyter session in the browser. That way, the input as well as the output is documented and can be extended with text blocks, headings et cetera.

https://github.com/takluyver/bash_kernel

Install with: pip install [--upgrade] jupyter bash_kernel

Short commands:

• nb: Start a new bash kernel notebook in the log directory. Next, click "New", "Bash".

This plugin provides shortcuts for installing software using homebrew cask.

search vlc
install vlc
uninstall vlc

Or, in German (for parents :-) )

suche skype
installiere skype
deinstalliere skype

Using karabiner I have remapped my keyboard.

p ü + ö ä # < -   (layout: de)
----------------------------------
\ { }   [ ] |     Alt_L
\ { }   [ ] | ~   Cmd_R
  [ ]             Alt_L + Shift_L

Karabiner provides a command-line interface to activate or deactivate settings:

karabiner set karabiner set remap.optionR2forwarddelete 1
karabiner set karabiner set remap.optionR2forwarddelete 0

Also, this script provides a short comamnd to create and apply new key remappings.

They keycodes can be looked up here: https://github.com/tekezo/Karabiner/blob/master/src/bridge/generator/keycode/data/KeyCode.data

But be aware, they always refer to the us keyboard layout.

create-key-map slash backslash
create-key-map "slash shift" backslash

The new mapping is appended to ~/Library/Application Support/Karabiner/private.xml.

Manual: https://pqrs.org/osx/karabiner/xml.html.en

To edit this file, just type:

This repository contains some shared libraries and extensions I use in my latex projects.

They can be symlinked or hardlinked into existing projects:

cd /path/to/my/latex/project
ln -s ~/.zsh/oh-my-zsh-customization/plugins/latex/lib lib
hln ~/.zsh/oh-my-zsh-customization/plugins/latex/lib lib

Or, with this extension, short:

cd /path/to/my/latex/project
latex-link-lib
latex-unlink-lib

When hardlinked, the lib directory is included in git's source control.

The hln command is defined in https://github.com/selkhateeb/hardlink and can be installed on mac os using brew install hardlink-osx.

Then the shread libraries can be included into the tex document:

% /path/to/my/latex/project/main.tex
% ...
% \input{lib/todo}

Prefix any command with lcars if you like.

Play random lcars sound from ~/Music/lcars. This requires brew install mplayer coreutils.

lcars-sound

Display terminal head with system info in lcars style.

lcars-new

This is executed when the plugin is included, i.e. don't use it together with the welcoem plugin. POWERLEVEL9K_MULTILINE_FIRST_PROMPT_PREFIX="▇▇▇▇▇▇▇▇▇▇▇\n▇▇▇▇▇▇▇▇▇▇▇ " POWERLEVEL9K_MULTILINE_SECOND_PROMPT_PREFIX="▇▇▇▇▇▇▇▇▇▇▇ ➜ " ◖ button ◗ export POWERLEVEL9K_LEFT_SEGMENT_SEPARATOR='◗ ◖' export POWERLEVEL9K_RIGHT_SEGMENT_SEPARATOR='◗ ◖' export POWERLEVEL9K_LEFT_SEGMENT_END_SEPARATOR='◗ ◖' export POWERLEVEL9K_LEFT_SUBSEGMENT_SEPARATOR='◗ ◖' export POWERLEVEL9K_RIGHT_SUBSEGMENT_SEPARATOR='◗ ◖'

I have taken this excellent zsh configuration from mooOS, the gnu/linux distro of shape shifting, time travelling alien space penguins, https://mooos.org.

These are some helpers for Rails and YourPlatform.

Here are some aliases to jump to directories. On the development machine, the projects are expected to be in ~/rails, on the production machine, in /var.

cdw  # wingolfsplattform
cdy  # your_platform
cdo  # your_platform_ops
cdp  # platforms_ops
cdm  # your_platform/demo_app/my_platform
cdv  # vademecum app

On our production machine, console logs in to the platform user and runs the rails console.

Some shortcuts for bundler:

be    # bundle exec, with lcars sound ;)
bi    # bundle install
bu    # bundle update

Shortcut for bin/rake:

r

Shortcut for bin/rails server:

s

When starting pry within a rails project, the config/environment is used automatically. No need to call pry -r ./config/environment explicitly.

pry

Ship it! To merge the master branch into production just call production.

production

To generate the platform documentation for cdw and open it locally, call:

doc

Run bin/rspec in an orange-colored tab with lcars sounds.

rspec
rspec spec/models

Run specs with selenium rather than phantomjs.

SELENIUM=true rspec spec/features
selenium spec/features
selen spec/features

Run parallel tests

para spec/models

The node js binary path /usr/local/nodejs-binary/bin is added to the PATH by this script.

This plugin is for working with the powerlevel9k zsh theme. https://github.com/bhilburn/powerlevel9k

If the directory $ZSH_CUSTOM/themes/powerlevel9k is missing, it is fetched from https://github.com/bhilburn/powerlevel9k.

If you want to use the theme, please specify it in your ~/.zshrc.

# ~/.zshrc
# ...
ZSH_THEME="powerlevel9k/powerlevel9k"

See also: https://github.com/bhilburn/powerlevel9k/wiki/Install-Instructions

You may configure powerlevel9k in ~/.zshenv using environment variables. But this plugin sets some nice defaults.

See also: https://github.com/bhilburn/powerlevel9k/wiki/Stylizing-Your-Prompt And: https://gist.github.com/athityakumar/1bd5e9e24cd2a1891565573a893993eb

This plugins prints some useful information about the current machine when opening a new terminal.

This is done using screenfetch. Install with brew install screenfetch.

Next to the starfleet sign, of course :)

I've taken this from mooos: https://github.com/idk/moo-skel
