Personal dotfiles for Bash, Zsh, tmux, and Ghostty — designed to work across macOS, Arch Linux, Ubuntu, Fedora, and NixOS. Uses GNU Stow to symlink files into $HOME and a modular installer that can set up or revert everything in one command.

Quick Start

git clone <repo-url> ~/Projects/my-shell
cd ~/Projects/my-shell
./setup            # install everything
./setup -r         # revert to backups

The setup script runs each module in install.d/ in order: create directories, configure Bash, configure Zsh, then stow dotfiles.

Libraries (lib/)

Library	Description
require.sh	Module loader for Bash — sources scripts by name with dedup guards
logger.sh	Colored, leveled logging (debug/info/warn/error/fatal) with style helpers

Using bin/ and lib/ Scripts

Sourcing the Libraries

Libraries live in .local/share/my/lib/bash/. Source them directly or use require.sh for dedup-safe loading:

PROJECT_ROOT=$(git rev-parse --show-toplevel)

# Direct source
source "$PROJECT_ROOT/.local/share/my/lib/bash/logger.sh"

# Via require.sh (safe to call multiple times — loads each module at most once)
source "$PROJECT_ROOT/.local/share/my/lib/bash/require.sh" logger

require.sh resolves modules by name from $MY_LIB_DIR/bash/, or by explicit path if the argument starts with / or ./.

Logging

logger.sh provides leveled logging controlled by LOG_LEVEL (default: 1 = ERROR and above):

LOG_LEVEL=8  # enable all levels
export LOG_LEVEL

debug "low-level detail"   # level 8
info  "status message"     # level 4
warn  "something is off"   # level 2
error "something failed"   # level 1
fatal "unrecoverable"      # level 0 — also calls exit 1

Style helpers are available for ad-hoc output:

bold_green "Done!"
dim "skipping..."
red "uh oh"

Colors are auto-disabled when stdout is not a terminal (e.g. when output is captured or piped).

Pattern: UI-Aware Top-Level Scripts

Child scripts (workers, installers, helpers) should write freely to stdout/stderr and exit with meaningful codes. Top-level scripts that interact with the desktop or a user-facing UI own the notification layer — they capture child output and handle it in an EXIT trap.

#!/usr/bin/env bash

on_exit() {
  if (( $? > 0 )); then
    notify-send "ERROR $(basename "$0")" "An error occurred:\n\n$msg"
    error "$msg"
  else
    notify-send "Success!" "$msg"
  fi
}

set -euEo pipefail

trap on_exit EXIT

PROJECT_ROOT=$(git rev-parse --show-toplevel)
source "$PROJECT_ROOT/.local/share/my/lib/bash/logger.sh"

msg=""  # initialize before any early exit so the trap is always safe

msg=$("$PROJECT_ROOT/.local/share/my/bin/some-child-script" "$@" 2>&1)

Key points:

• set -euEo pipefail — exit on any error, unset variable, or pipe failure
• trap on_exit EXIT — the handler always runs, success or failure
• msg="" — must be initialized before the first command that can fail; otherwise set -u will crash the trap if it fires early
• 2>&1 — merges stderr into stdout so the full child output (logs + errors) becomes the notification body

bin/ Scripts

The bin/ scripts are standalone and callable from any script once $MY_BIN_DIR is on $PATH (set up by the shell config after install):

# Detect OS
os=$(sys-get-os)           # → "arch", "ubuntu", "macos", etc.

# Install packages (skips already-installed)
sys-pkg-install git curl ripgrep

# Check if a package is present
sys-pkg-check fzf && echo "fzf is installed"

AI Tools (ai-call-ollama, ai-git-commit-msg)

These scripts talk to an Ollama API endpoint. The target host is controlled by the OLLAMA_HOST environment variable, which defaults to http://localhost:11434.

shared.envs.sh sets OLLAMA_HOST to a remote instance. To override it for a session, or to point at a local Ollama instance instead:

export OLLAMA_HOST="http://localhost:11434"

To make the override permanent, add the export to ~/ollama.env.sh (this file is sourced automatically by shared.envs.sh when it exists, and is gitignored):

echo 'export OLLAMA_HOST="http://localhost:11434"' >> ~/ollama.env.sh

ai-call-ollama

Send a prompt to any Ollama model and print the response:

# Basic usage
ai-call-ollama -m llama3.2 -s "You are a terse assistant." -p "What is a VLAN?"

# Pipe the user prompt from stdin
echo "Explain BGP in one sentence." | ai-call-ollama -m qwen2.5-coder:14b -s "Be concise."

# Stream the raw response as it generates
ai-call-ollama -m mistral -s "You are helpful." -p "Summarize TCP/IP." --stream

Flag	Description
-m, --model	Model name (e.g. llama3.1, qwen2.5-coder:14b)
-s, --system	System prompt
-p, --prompt	User prompt (or pipe via stdin)
--stream	Stream raw JSON lines as the model generates

Requires curl and jq.

ai-git-commit-msg

Generate a Conventional Commit message from the currently staged diff, open it in $EDITOR for review, then commit:

git add -p          # stage your changes
ai-git-commit-msg   # generate, edit, and commit

The script uses qwen2.5-coder:14b by default and respects OLLAMA_HOST.

Shell Integrations

The Zsh config auto-detects and initializes these tools when available:

• Starship — prompt
• fzf — fuzzy finder
• zoxide — smarter cd
• mise — runtime/tool version manager
• ngrok — tunneling
