"dotfiles" and system configuration

Target platforms: macOS and Red Hat-like Linuxes (eg. CentOS).
Set-up method: ~~Beautiful and intricate snowflake~~ an incredibly over-engineered custom configuration framework called Fig.
Visible in the screenshot:
- default-dark Base16 color scheme (see screenshots of other colorschemes).
- Adobe Source Code Pro (Light) font.
- Vim, running inside tmux, inside iTerm2, on macOS "High Sierra".

Features

Dotfiles

A set of dotfiles that I've been tweaking and twiddling since the early 2000s (under version control since 2009). Characteristics include:

Sane Vim pasting via bracketed paste mode.
Write access to local clipboard from local and remote hosts, inside and outside of tmux (via Clipper).
Full mouse support (pane/split resizing, scrolling, text selection) in Vim and tmux.
Focus/lost events for Vim inside tmux.
Cursor shape toggles on entering Vim.
Italics in the terminal.
Bundles a (not-excessive) number of useful Vim plug-ins.
Conservative Vim configuration (very few overrides of core functionality; most changes are unobtrusive enhancements; some additional functionality exposed via <Leader> and <LocalLeader> mappings.
Relatively restrained Zsh config, Bash-like but with a few Zsh perks, such as right-side prompt, auto-cd hooks, command elapsed time printing and such.
Unified color-handling (across iTerm2 and Vim) via Base16 Shell.
Encrypted versioning of files with sensitive content (via git-cipher).
Comprehensive Hammerspoon config.

Homebrew

On macOS, the "homebrew" aspect installs a bunch of useful software.

Keyboard customization

On macOS, Karabiner-Elements is used for the following:

Make Caps Lock serve as Backspace (when tapped) and Left Control (when chorded with another key). When held down alone, Caps Lock fires repeated Backspace events.
Make Return serve as Return (when tapped) and Right Control (when chorded with another key). When held down alone, Return fires repeated Return events.
Maps Control-I to F6 (only in MacVim and the terminal) so that it can be mapped independently from Tab in Vim.
Toggle Caps Lock on by tapping both Shift keys simultaneously.
Makes the function keys on my external Realforce keyboard behave like the "media" keys on Apple's keyboards.
Swap Option and Command keys on my external Realforce keyboard.
Make the "application" key (extra modifier key on right-hand side) behave as "fn" on Realforce keyboard.
Make "pause" (at far-right of function key row) behave as "power" (effectively, sleep) on Realforce keyboard.
Adds a "SpaceFN" layer that can be activated by holding down Space while hitting other keys; I use this to make the cursor keys available on or near the home row in any app.

Zsh

Functions

ag: Transparently wraps the ag executable so as to provide a centralized place to set defaults for that command (seeing as it has no "rc" file).
bounce: bounce the macOS Dock icon if the terminal is not in the foreground.
color: change terminal and Vim color scheme.
fd: "find directory" using fast bfs and sk; automatically cds into the selected directory.
fh: "find [in] history"; selecting a history item inserts it into the command line but does not execute it.
history: overrides the (tiny) default history count.
jump (aliased to j): to jump to hashed directories.
regmv: bulk-rename files (eg. regmv '/\.tif$/.tiff/' *).
scratch: create a random temporary scratch directory and cd into it.
tick: moves an existing time warp (eg. tick +1h); see tw below for a description of time warp.
tmux: wrapper that reattches to pre-existing sessions, or creates new ones based on the current directory name; additionally, looks for a .tmux file to set up windows and panes (note that the first time a given .tmux file is encountered the wrapper asks the user whether to trust or skip it).
tw ("time warp"): overrides GIT_AUTHOR_DATE and GIT_COMMITTER_DATE (eg. tw -1d).

Prompt

Zsh is configured with the following prompt:

Visible here are:

Concise left-hand prompt consisting of:
- Last component of current directory (abbreviates $HOME to ~ if possible).
- Prompt marker, ❯, the "HEAVY RIGHT-POINTING ANGLE QUOTATION MARK ORNAMENT" (that's \u276f, or e2 9d af in UTF-8).
Extended right-hand size prompt which auto-hides when necessary to make room for long commands and contains:
- Duration of previous command in adaptive units (seconds, minutes, hours, days, depending on duration).
- Current version control branch name.
- Current version control worktree status using colors that match those used in git status:
  - Green dot indicates staged changes.
  - Red dot indicates unstaged changes.
  - Blue dot indicates untracked files.
- Full version of current working directory (again, abbreviating $HOME to ~).

Nested shells are indicated with additional prompt characters. For example, one nested shell:

Two nested shells:

Root shells are indicated with a different color prompt character and the word "root":

Nesting within a root shell is indicated like this:

Two nested shells:

If the last command exited with a non-zero status (usually indicative of an error), a yellow exclamation is shown:

If there are background processes, a yellow asterisk is shown:

Dependencies

tmux 2.3 or later.
Neovim or Vim 8.0 or later with Ruby and Python support (although there's a reasonable amount of feature detection in order to degrade gracefully).
Relatively recent Zsh.
Relatively recent Git.
Clipper for transparent access to the local system clipboard.
On macOS, iTerm2. Additionally, only the latest version of macOS (although at the time of writing, I'm still on High Sierra) gets actively tested.
Ruby.
Adobe Source Code Pro or any other fixed-width font that includes the Powerline glyphs.

Installation

Clone

git clone --recursive https://github.com/wincent/wincent.git

Install

⚠️ WARNING: There are lots of different things that can be installed or configured (see the "aspects" directory). Unless you want your machine to be exactly like mine — which is unlikely — you probably don't want to install everything. Maybe you don't even want everything in the "dotfiles" and "vim" aspects. Please inspect the contents of each aspect before proceeding to install it; you may even be better off just looking at the configuration files and stealing the bits that you find interesting or useful (everything is in the public domain, unless otherwise indicated).

At the time of writing, these are the aspects, which you can expect to change over time:

automator: Scripts for use with Automator
automount: Sets up macOS's automount facility
backup: Backup scripts
cron: Sets up cron files
defaults: Sets up defaults (ie. preferences) on macOS
dotfiles: Creates symlinks in $HOME to the dotfiles in this repo
fonts: Installs Source Code Pro font files
homebrew: Installs and updates Homebrew
iterm: Dynamic profiles for iTerm
karabiner: Configures Karabiner-Elements
launchd: Configures launchd
meta: Tests the configuration framework
node: Installs Node.js
ruby: Installs Ruby gems
shell: Sets the use shell to zsh
ssh: Manages local SSH config
tampermonkey: Sets up UserScripts
terminfo: Sets up terminfo database entries for italics and 256-color support
vim: Configures Vim

Examples

./install dotfiles vim      # Just install "dotfiles" and "vim" stuff.
./install dotfiles          # Just install "dotfiles".
./install dotfiles --step   # Prompt for confirmation at each step.
./install dotfiles --check  # Do a dry-run, showing what would be changed.
./install                   # Install everything.
./install --help            # Info on installing specific rol

This sets up a local Node environment using n, and then uses Fig to copy the dotfiles and configure the machine.

Note: Given that ~/.gitconfig is included with these dotfiles, any local modifications or overrides that you apply should be added to ~/.gitconfig.local instead; for example:

git config --file ~/.gitconfig.local user.name "John Doe"
git config --file ~/.gitconfig.local user.email johndoe@example.com

Troubleshooting

General troubleshooting

There are a few useful ./install options:

# Run in "check" (dry-run) mode.
./install --check

# Show debugging information during the run.
./install --debug

# Confirm each task before running it (--step), and begin
# execution from a specific task (--start-at-task) in a
# specific aspect ("dotfiles").
./install --step --start='make directories' dotfiles

Broken Unicode in Vim (Linux)

If Unicode symbols appear missing or corrupted in Vim, first ensure that your terminal emulator supports UTF-8. Then, check to see if you've properly configured your system-wide UTF-8 support.

Issue this test command:

export LC_ALL=en_US.UTF-8

Then run vim. Unicode in the statusline should be working.

To persist this LC_* variable binding, edit your locale accordingly:

/etc/locale.conf

LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8
