dotfiles

I'm documenting this primarily for personal use. This repository contains shell configs, vim configs, emacs configs, a list of commonly used applications, and other items.

Configuration is everything.

Setting up new computer

1. Install Dropbox

$ cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -
$ crontab -e # add the following line...
@reboot ~/.dropbox-dist/dropboxd 2>&1 >/tmp/dropbox.log
$ reboot            # 1/3 verify installation
$ pgrep dropbox     # 2/3 verify installation
$ dropbox.py status # 3/3 verify installation

1. Authorize computer to access dotfiles

$ ssh-keygen -t rsa -b 4096 -C 'wpcarro@gmail.com'
$ eval $(ssh-agent -s)
$ ssh-add ~/.ssh/id_rsa
$ xclip -sel clip <~/.ssh/id_rsa.pub
$ browse github.com # paste ssh public key in settings
$ mkdir ~/programming
$ git clone git@github.com:wpcarro/dotfiles ~/Dropbox/dotfiles

1. Install Antigen, Vundle, nix-env for package management

$ # antigen
$ curl -L git.io/antigen >~/antigen.zsh
$ # vundle
$ g clone VundleVim/Vundle.vim ~/.config/nvim/bundle/Vundle.vim
$ # nix-env
$ curl https://nixos.org/nix/install | sh
$ for p in $(cat nix-env.txt); do
>   nix-env -i "$p"
> done

1. Install shared executables

Some files should be kept out of this repository. Things that come to mind include secrets (e.g. monzo_creds.json.gpg) and binaries.

Secrets should be kept out of this repository in case. It might be okay to include them herein since they should be encrypted. But just to add an additional layer of security, I avoid adding them.

Executables are kept out of version control since they can be quite large. For example, my /usr/bin is 8.9G at the time of this writing. Also it can be noisy to see diffs of binaries after upgrading programs.

While sharing binaries across systems feels brittle, everything should function as long as the machines across which the binaries are shared run Linux and have i386 architectures.

$ ln -s ~/Dropbox/bin ~/bin

1. Install i3

$ sudo apt-get install i3

1. Install dotfiles

TODO: include steps 2-4 in the make install command.

$ cd ~/Dropbox/dotfiles
$ DOTFILES="$(pwd)" make install

TODOS

• support dependencies like terminal themes

SSHFS

TODO: add explanation about unison, rsync, etc.

SSHFS enables seamless file transfers from your local machine to a remote machine.

Usage

Assuming your remote machine is configured in your ~/.ssh/config (see above), you can mount your remote machine's home directory on your local machine like so:

$ mkdir ~/ec2
$ sshfs ec2:/home/ubuntu ~/ec2 -o reconnect,follow_symlinks

Now your remote machine's home directory can be accessed using the ~/ec2 directory. This directory can be treated as if it were an ordinary local directory. To illustrate how easy it is to use, let's install Vundle onto our remote machine.

$ git clone https://github.com/VundleVim/Vundle.vim.git ~/ec2/.vim/bundle/Vundle.vim

Voila! We now have Vundle installed on our ec2 instance without needing to manually SSH into that machine.

GnuPG

Entering a new system?

$ ./configs/shared/gpg/.gnupg/import.sh path/to/directory

Leaving an old system? TODO: create a job that runs this periodically.

$ ./configs/shared/gpg/.gnupg/export.sh [directory]

Reference

- sec: secret key
- pub: public key
- ssb: secret sub-key
- sub: public sub-key

GnuPG + Git

1. Register newly created [S] signing subkey as signingkey
2. Enforce commit-signing
3. Opt into gpg2 usage

$ git config --global user.signingkey <SIGNING_KEY>
$ git config --global commit.gpgsign true
$ git config --global gpg.program gpg2

GnuPG + GPG-Agent

Setup gpg-agent to use password caching by adding the following entries to ~/.gnupg/gpg-agent.conf (already done in this repository):

default-cache-ttl 300 max-cache-ttl 3600

True Color and Italics

At the time of this writing, Suckless's st terminal provides True Color and italics support. It's also important to test that this support remains when inside of Vim or inside of a Tmux session or both.

TrueColor

To test for your terminal's True Color support, run:

$ test_true_color

Enable TrueColor in your init.vim (already done in this repository):

set termguicolors

Italics

To test if your terminal supports italics and other text treatments, run:

$ test_text_formatting

Ligatures

At the time of this writing, Suckless's st does not appear to support ligatures.

Miscellaneous notes

• Executables are shared at ~/Dropbox/bin and not kept within this repository to avoid the bloat.
• Map <CAPS_LOCK> key to <ESC>
• Increase key-repeat rate
• Decrease key-repeat-delay
• Increase mouse speed
