dotfiles

Personal dotfiles including various rc files in $HOME.

Topics

bashrc-setups/

.bashrc patterns that have stood the test of time across 5+ machines:

• Githome — versioning dotfiles via git init --bare $HOME/.githome
• Function composition — codex-* wrappers built from cdx-e-* argument generators
• export_append / export_prepend — idempotent colon-separated path manipulation
• Echo/debug patterns — local -; set -x, argument arrays with inline comments, log capture

git-private-public/

Dual .git directories for clean separation of local (private) and GitHub (public) configs:

• .git → .git-private by default (machine-specific email, local remotes)
• .git → .git-public when pushing to GitHub (public email, GitHub remotes)
• Private notes with keys/tokens live in .git-private commits, never reach GitHub
• This very dotfiles/ repo uses this pattern

git-bare-repo-worktrees/

Nested git repos for contributing to OSS while keeping private notes versioned:

• Private parent repo for notes (README.LJ, LEARNINGS.md, CLAUDE.md)
• Bare public child repo for code (github/.git — bare clone of fork)
• Worktrees for branch isolation (worktrees/feature-a, worktrees/upstream-main)
• See also: ~/.claude/skills/git-bare-repo-worktrees.md for reusable skill template

.hammerspoon/

Chrome window manager via Hammerspoon:

• Cmd-1…9 — focus Nth Chrome window (9 = last); scoped to Chrome only
• Cmd-0 — interactive chooser with reordering, save/reset, ⌥↑/⌥↓ to move
• Cmd-Alt-Ctrl-H — reload config
• Window title cleanup, AXTitle support, persistent custom ordering
• Installed via githome + symlink pattern (~/.hammerspoon → .hammerspoon-macbook2)
