My dotfiles. https://github.com/davidosomething/dotfiles

• I use macOS, Arch Linux, and Debian. Limited Fedora support.
• XDG compliance wherever possible to keep $HOME clean
  • See Arch Linux wiki for XDG Base Directory Support
  • See Debian DotFilesList
  • See grawity's notes and environ notes
• Wezterm as preferred cross-platform terminal
• ZSH (preferred) and BASH configs
• Neovim (preferred) and VIM configs
• RC files for Lua, markdownlint, node, PHP, python, R, and others

Installation

See macOS specific notes in mac/README.md

Generally:

git clone https://github.com/davidosomething/dotfiles ~/.dotfiles

Then, run the bootstrap/symlink script for linux or bootstrap/mac for macOS.

After symlinking, bootstrap/cleanup can detect and move pre-existing dotfiles that conflict with these (mac does this).

Dev environment setup

After symlinking and restarting shell, aliases will be available. The sshkeygen alias will help in generating a new SSH key.

node, python, and ruby

Use rtx or asdf

Provisioning scripts

These will assist in installing packages and dotfiles. Best to have the environment set up first.

• bootstrap/cleanup moves some dotfiles into their XDG Base Directory supported directories and deletes unnecessary things (with confirmation).
• bootstrap/mac provision macOS. Runs other bootstrappers.
• bootstrap/symlink symlinks rc files for bash, ZSH, ack, (Neo)vim, etc.

Updating

u is an alias to dot. Use u without arguments for usage.

Notes

• bin/
  • There's a readme in bin/ describing each script/binary. This directory is in the $PATH.
• git/
  • The comment character is # instead of ; so I can use Markdown in my commit messages without trimming the headers as comments. This is also reflected in a custom Vim highlighting syntax in vim/after/syntax/gitcommit.vim.
• local/
  • Unversioned folder, put zshrc, bashrc, npmrc, and gitconfig here and they will be automatically sourced, LAST, by the default scripts. No dots on the filenames.
• nvim/
  • nvim/README.md for more information.
• python/
  • Never sudo pip. Set up a python virtual environment.
• vim/
  • Not really maintained, I use neovim on all my systems now
  • See vim/README.md for more information.

rc script source order

If you have node installed, the dkosourced command will show you (not exhaustively) the order scripts get sourced. Without node echo $DKO_SOURCE works.

For X apps (no terminal) the value may be:

/etc/profile
.xprofile
  shell/vars
    shell/xdg

Shell script code style

• Script architecture
  • Use the #!/usr/bin/env bash shebang and write with bash compatibility
  • Create a private main function with the same name as the shell script. E.g. for a script called fun, there should be a __fun() that gets called with the original arguments __fun $@
  • Two space indents
  • Prefer . over source
• Function names
  • For private functions in a script, use two underscores __private_func() These function names are safe to reuse after running the script once. When namespaced, they are in the form of __dko_function_name().
• Variable interpolation
  • Always use curly braces around the variable name when interpolating in double quotes.
• Variable names
  • Stick to nouns, lower camel case
• Variable scope
  • Use local and readonly variables as much as possible over global/shell-scoped variables.
• Comparison
  • Not strict on POSIX, but portability
  • Do NOT use BASH arrays, use ZSH or Python if need something complicated
  • Use BASH == for string comparison
  • Use BASH (( A == 2 )) for integer comparison (note not $A, $ not needed)
