My personal configurations for various tools.

Color Scheme

I use a bleeding-edge terminal with an 18 color palette. The colors are inspired by Solarized and are designed to be readable in a light or dark theme that can be switched simply by swapping the shades of grey. The palette is generated with colors.py using parameters from colors.yml; there's more details about the algorithm inside the Python script.

Tooling

Most of the interesting configuration here is for vim, tmux, and zsh. openbox has a fair amount of custom keybindings to place windows on my screen, but it's hardcoded to a 3440x1440 resolution monitor.

Docker workspaces

I describe my dev environment in a Dockerfile and use this image to spin up clean instances to isolate my various projects and workstreams. This image contains an up-to-date copy of my ideal dev environment. There is a zsh function d() for creating and entering these workspaces. Executing d foo will create a new Docker workspace named foo if it doesn't exist, or enter an existing foo workspace. Likewise, d foo ls will execute ls inside the workspace. The ~/dev container directory is persisted as a bind mount to ~/.workspaces/foo on the host.

Using this method allows me to focus on a "stateless" development methodology: my development environment is completely documented as code and can be deleted / re-created completely automatically. This reduces investment and allows me to have a consistent and reproducible environment on any box with Docker installed.

tmux

Because I use tmux so heavily in my workflow, there is a zsh function t() that simplifies the process of creating new sessions and attaching to them. Simply typing t foo will create a new tmux session named foo if it doesn't exist, or attach to an existing foo session, while t foo:bar will ssh into foo and create/attach to bar and t foo/bar will enter the foo Docker workspace and create/attach to bar.

I have several custom tmux bindings that use alt chords instead of a prefix chain. Briefly:

• alt+\ splits the pane vertically
• alt+- splits the pane horizontally
• alt+hjkl switch between panes
• alt+mn switch between windows
• alt+, creates a new window
• alt+d detaches from the session
• alt+s switches sessions
• alt+backspace switches pane layouts
• alt+z toggles zoom on the current pane
• alt+w toggles pane synchronization
• alt+; enters the tmux command prompt
• alt+c enters copy-mode; y will copy selection
• alt+p pastes a copied selection

vim

I use vim for editing all text. I have a relatively minimal plugin setup that mostly consists of syntax files. I do use skim.vim, ALE, and YouCompleteMe fairly heavily.

I have several custom vim bindings that are explained in my vimrc, but the ones that I seem to miss the most when working on non-configured systems are ctrl+hjkl to switch between splits, ctrl+mn to move between buffers, and ctrl+d to suspend. These mirror the corresponding alt bindings for tmux.
