**The issmirnov/dotfiles repository combines Dotbot, shell scripts, and an Ansible role to provide one-command automation for bootstrapping complete development environments on any machine.**

Setting up a new development machine manually is error-prone and time-consuming. The issmirnov/dotfiles repository demonstrates how to automate dotfiles setup using a lightweight, modular toolchain that handles symlinking, OS-specific configuration, and environment reloading automatically.

## Core Automation with Dotbot and Shell Wrappers

The foundation of the automation pipeline is **Dotbot**, a lightweight YAML-driven installer included as a Git submodule declared in `.gitmodules`. Dotbot creates symlinks, executes shell commands, and cleans obsolete files based on declarative configuration files.

The repository provides two shell wrappers that invoke Dotbot with different configurations:

**`install`** – The primary Bash script located at [`install`](https://github.com/issmirnov/dotfiles/blob/master/install) executes the full setup. It initializes the Dotbot submodule, then runs Dotbot against [`default.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/default.conf.yaml) followed by OS-specific configurations ([`ubuntu.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/ubuntu.conf.yaml) or [`osx.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/osx.conf.yaml)).

**`minstall`** – A minimal Bash script at [`minstall`](https://github.com/issmirnov/dotfiles/blob/master/minstall) designed for headless servers or CI environments. It runs Dotbot with [`minimal.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/minimal.conf.yaml) only, linking essential files like `zshrc` and Git hooks while skipping UI-heavy configurations.

### Configuration Files That Drive Automation

Dotbot reads its instructions from YAML configuration files stored in the repository root:

- **[`default.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/default.conf.yaml)** – Defines the core symlink mappings (e.g., `~/.zshrc` → `zsh/zshrc`), shell commands for installing dependencies, and default settings.
- **[`ubuntu.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/ubuntu.conf.yaml)** and **[`osx.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/osx.conf.yaml)** – OS-specific extensions that add platform-dependent packages and settings.
- **[`minimal.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/minimal.conf.yaml)** – A stripped-down configuration for lightweight environments.

## Ansible Integration for Team Provisioning

For organizations already using Ansible, the repository publishes a ready-to-use role on Ansible Galaxy. The `issmirnov.dotfiles` role, documented in [[`README.md`](https://github.com/issmirnov/dotfiles/blob/main/README.md)](https://github.com/issmirnov/dotfiles/blob/master/README.md#ansible), reproduces the entire Dotbot-driven setup within an Ansible playbook.

Add the role to your [`requirements.yml`](https://github.com/issmirnov/dotfiles/blob/main/requirements.yml):

```yaml

# requirements.yml

- src: issmirnov.dotfiles
  version: master

```

Then include it in your playbook:

```yaml
- hosts: all
  roles:
    - issmirnov.dotfiles   # executes the same automation under the hood

```

This allows infrastructure teams to automate dotfiles setup across fleets of developer machines using their existing configuration management workflows.

## Live Environment Reloading

Automation does not stop at installation. The repository includes mechanisms to keep the environment synchronized when dotfiles change.

**Zsh Setup Script** – Located at [`zsh/setup`](https://github.com/issmirnov/dotfiles/blob/master/zsh/setup), this script is invoked by Dotbot immediately after symlinks are created. It sources the newly linked `~/.zshrc` to ensure the configuration is active in the current shell without requiring a manual restart.

**Git Hook Templates** – The [`default.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/default.conf.yaml) configures post-checkout, post-commit, and post-merge hooks (e.g., at `~/.dotfiles/.git/hooks/post-checkout`) that automatically reload the environment whenever you pull changes or switch branches. This provides a "live-reload" experience for developers actively modifying their dotfiles.

## Quick Start: Automating Your Setup

New developers can bootstrap a complete environment using the following patterns.

Full desktop or laptop installation:

```bash

# Clone the repository

git clone https://github.com/issmirnov/dotfiles.git ~/.dotfiles
cd ~/.dotfiles

# Execute the main installer

./install

```

The `install` script handles submodule initialization, symlinking, OS detection, and plugin installation automatically.

Minimal server installation:

```bash
cd ~/.dotfiles
./minstall   # Runs Dotbot with minimal.conf.yaml only

```

Ansible-driven provisioning:

```yaml

# In your playbook

- hosts: developers
  roles:
    - issmirnov.dotfiles

```

## Summary

- **Dotbot** serves as the core automation engine, driven by YAML configurations like [`default.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/default.conf.yaml) and [`minimal.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/minimal.conf.yaml).
- The **`install`** and **`minstall`** scripts provide one-command wrappers that handle OS detection and environment-specific setups.
- **Ansible Galaxy integration** enables teams to automate dotfiles setup at scale using the `issmirnov.dotfiles` role.
- **`zsh/setup`** and Git hook templates ensure the environment reloads automatically when configurations change.
- All automation logic is tracked in the repository root files: `install`, `minstall`, [`default.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/default.conf.yaml), and `.gitmodules`.

## Frequently Asked Questions

### What is Dotbot and why is it used for dotfiles automation?

Dotbot is a lightweight, Python-based installation tool that reads YAML configuration files to create symlinks, run shell commands, and clean up old files. According to the issmirnov/dotfiles source code, it is included as a Git submodule and driven by [`default.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/default.conf.yaml) to automate the entire linking process without manual file copying.

### How does the install script detect the operating system?

The `install` script detects the host OS by checking `uname -s` and then appends the appropriate configuration file—either [`ubuntu.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/ubuntu.conf.yaml) for Linux or [`osx.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/osx.conf.yaml) for macOS—to the Dotbot execution list. This ensures platform-specific packages and settings are applied automatically during setup.

### Can I use these dotfiles in a headless server or CI environment?

Yes. The `minstall` script is specifically designed for lightweight environments. It runs Dotbot with [`minimal.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/minimal.conf.yaml) only, which links essential files like `zshrc` and Git hooks while excluding UI-related configurations, making it ideal for servers and continuous integration pipelines.

### How do the dotfiles automatically reload after I pull updates?

The repository uses Git hook templates configured in [`default.conf.yaml`](https://github.com/issmirnov/dotfiles/blob/main/default.conf.yaml) to install post-checkout, post-commit, and post-merge hooks. These hooks trigger environment reloads automatically when you pull changes or modify the repository, ensuring your active shell always reflects the latest configuration without manual intervention.
