🚀 Quick Start

Install on Linux/macOS

sh -c "$(curl -fsLS https://get.chezmoi.io)" -- init --apply DevSecNinja

Or clone and install locally:

git clone https://github.com/DevSecNinja/dotfiles.git
cd dotfiles
./install.sh

Install on Windows (PowerShell)

Option 1: Direct from GitHub (PowerShell 5.1+ or PowerShell 7+)

# Using the official chezmoi installer (recommended)
(irm -useb https://get.chezmoi.io/ps1) | powershell -c -; chezmoi init --apply DevSecNinja

Option 2: Clone and install locally

git clone https://github.com/DevSecNinja/dotfiles.git
cd dotfiles
.\install.ps1

Install on WSL (Windows Subsystem for Linux)

Use the Linux installation method inside your WSL distribution:

sh -c "$(curl -fsLS https://get.chezmoi.io)" -- init --apply DevSecNinja

The dotfiles will automatically detect WSL and apply appropriate configurations.

Install in Coder Workspaces

This repository supports Coder workspaces out of the box. The install.sh and install.ps1 scripts in the repository root will be automatically discovered and executed by Coder when setting up a new workspace with dotfiles enabled.

To use this dotfiles repository in Coder:

1. Navigate to your Coder workspace settings
2. Enable dotfiles support
3. Set the dotfiles repository URL to: https://github.com/DevSecNinja/dotfiles
4. Coder will automatically run install.sh (Linux/macOS) or install.ps1 (Windows) during workspace setup

For more information, see the Coder Dotfiles Documentation.

Development Container (DevContainer)

This repository includes a complete DevContainer configuration for Visual Studio Code and GitHub Codespaces. The devcontainer provides a fully configured development environment with:

Pre-installed Features:

• 🍺 Homebrew package manager
• 📦 Git LFS (Large File Storage)
• 💻 PowerShell with Pester testing framework
• 🐍 Python (latest version)
• 🐙 GitHub CLI

Automatic Setup:

• ✅ Dotfiles automatically installed via postCreateCommand
• ✅ Fish shell configured as default terminal
• ✅ All configurations applied and verified
• ✅ VSCode extensions pre-installed (GitHub Copilot, Pester)

Prebuilt Images:

• 🚀 Prebuilt devcontainer images are automatically built and published to GitHub Container Registry
• 🏗️ Images are rebuilt weekly and on every devcontainer configuration change
• ⚡ CI workflows use prebuilt images for faster test execution
• 📦 Available at: ghcr.io/devsecninja/dotfiles-devcontainer:latest

Using the DevContainer:

1. In VSCode:

   • Open this repository in VSCode
   • Install the "Dev Containers" extension
   • Click "Reopen in Container" when prompted
   • Or use Command Palette: Dev Containers: Reopen in Container

2. In GitHub Codespaces:

   • Navigate to this repository on GitHub
   • Click "Code" → "Codespaces" → "Create codespace on main"
   • The devcontainer will automatically build and configure
   • Optional: Enable Codespaces prebuilds in repository settings for even faster startup

3. Testing the DevContainer:

   # Run the devcontainer test script
   .github/scripts/test-devcontainer.sh

The CI pipeline automatically tests the complete devcontainer deployment, including feature installation, dotfiles setup, and postCreateCommand execution.

🔧 Customization

Personal Information

On first run, Chezmoi will prompt for:

• Name: Used in Git commits
• Email: Used in Git commits

To re-enter this information:

chezmoi init --data=false

📝 Common Commands

# Check what changes would be applied
chezmoi diff

# Apply changes
chezmoi apply

# Edit a file
chezmoi edit ~/.vimrc

# Add a new file
chezmoi add ~/.config/myapp/config.yaml

# Update from repository
chezmoi update

# View Chezmoi data (name, email, OS info)
chezmoi data

# Verify all managed files

Pre-commit Hooks

This repository uses pre-commit for code quality checks:

# Install dependencies
pip3 install -r requirements.txt

# Setup pre-commit hooks (from repository root)
home/.chezmoiscripts/linux/run_once_setup-precommit.sh

# Run manually on all files
pre-commit run --all-files

Hooks will automatically run on git commit. The checks include:

• ✂️ Trailing whitespace removal
• 📄 End-of-file fixes
• 🔍 YAML validation
• 🎨 Shell script formatting (shfmt)

These scripts and hooks are also used in the GitHub Actions CI pipeline to ensure quality.

🛠️ Development Tools

This repository includes Task and mise for streamlined development:

Task Runner

Task provides convenient commands for common operations:

# List all available tasks
task --list

# Install all dependencies (mise, go-task, Python packages)
task install:all

# Run all validation checks (required before commit)
task validate:all

# Run specific validations
task validate:chezmoi      # Validate Chezmoi config
task validate:shell        # Validate shell scripts
task validate:fish         # Validate Fish config

# Run tests
task test:all              # All tests
task test:chezmoi-apply    # Test Chezmoi apply

# Chezmoi operations
task chezmoi:init          # Preview changes (dry-run)
task chezmoi:diff          # Show differences
task chezmoi:verify        # Verify applied files

# Development setup
task dev:setup             # Complete dev environment setup

# CI tasks
task ci:validate           # Run CI validation pipeline

Mise (Tool Version Manager)

Mise manages tool versions defined in .mise.toml:

# Install mise-managed tools
mise install

# Show installed tools
mise list

# Upgrade all tools
mise upgrade

# Check mise configuration
mise doctor

Full mode installations automatically install both Task and mise. Light mode installs only mise.

Installation Modes

The repository supports two installation modes:

• Light mode (servers, CI, codespaces): Essential tools only
• Full mode (dev servers, workstations): Full development tooling including Task and mise

The mode is auto-detected based on:

• Hostname patterns (SVLDEV* = full, SVL* = light)
• Environment (codespaces, devcontainer, CI = light)
• Default = full mode

To change modes:

chezmoi init --data=false
