core/00-path.sh: PATH modifications for common tools - core/10-history.sh: History configuration - core/20-options.sh: Shell options, editor, locale - tools/git.sh: Git aliases (gs, ga, gc, gp, etc.) - tools/fzf.sh: Fuzzy finder with fd integration - tools/starship.sh: Starship prompt init - misc/aliases.sh: Navigation, ls variants, safety nets - misc/functions.sh: mkcd, extract, ff, fd, backup - os/linux.sh: Package manager aliases, systemd - os/macos.sh: Homebrew, macOS utilities - ui/colours.sh: Terminal and man page colours - ui/prompt.sh: Custom prompt with git branch Tests (tests/): - smoke_test.sh: Shell-based smoke test verifying: - Source files exist - Examples structure correct - SPDX headers present - Binary runs and creates directories - Idempotency works - test_shell_manager.adb: Ada unit tests for Shell_Manager - tests.gpr: GPRBuild project for tests README updates: -
