Dotbot ====== Dotbot makes installing your dotfiles as easy as `git clone $url && cd dotfiles && ./install`, even on a freshly installed system! --- [![Build Status](https://travis-ci.org/anishathalye/dotbot.svg?branch=master)](https://travis-ci.org/anishathalye/dotbot) Dotbot is a tool that bootstraps your dotfiles (it's a [Dot]files [bo]o[t]strapper, get it?). It does *less* than you think, because version control systems do more than you think. Dotbot is designed to be lightweight and self-contained, with no external dependencies and no installation required. Dotbot can also be a drop-in replacement for any other tool you were using to manage your dotfiles, and Dotbot is VCS-agnostic -- it doesn't make any attempt to manage your dotfiles. If you want an in-depth tutorial about organizing your dotfiles, see this [blog post][managing-dotfiles-post]. Get Running in 5 Minutes ------------------------ ### Starting Fresh? Great! You can automate the creation of your dotfiles by using the user-contributed [init-dotfiles][init-dotfiles] script. If you'd rather use a template repository, check out [dotfiles_template][dotfiles-template]. Or, if you're just looking for [some inspiration][inspiration], we've got you covered. ### Integrate with Existing Dotfiles The following will help you get set up using Dotbot in just a few steps. If you're using **Git**, you can add Dotbot as a submodule: ```bash cd ~/.dotfiles # replace with the path to your dotfiles git init # initialize repository if needed git submodule add https://github.com/anishathalye/dotbot cp dotbot/tools/git-submodule/install . touch install.conf.yaml ``` If you're using **Mercurial**, you can add Dotbot as a subrepo: ```bash cd ~/.dotfiles # replace with the path to your dotfiles hg init # initialize repository if needed echo "dotbot = [git]https://github.com/anishathalye/dotbot" > .hgsub hg add .hgsub git clone https://github.com/anishathalye/dotbot cp dotbot/tools/hg-subrepo/install . touch install.conf.yaml ``` To get started, you just need to fill in the `install.conf.yaml` and Dotbot will take care of the rest. To help you get started we have [an example](#full-example) config file as well as [configuration documentation](#configuration) for the accepted parameters. Note: The `install` script is merely a shim that checks out the appropriate version of Dotbot and calls the full Dotbot installer. By default, the script assumes that the configuration is located in `install.conf.yaml` the Dotbot submodule is located in `dotbot`. You can change either of these parameters by editing the variables in the `install` script appropriately. Setting up Dotbot as a submodule or subrepo locks it on the current version. You can upgrade Dotbot at any point. If using a submodule, run `git submodule update --remote dotbot`, substituting `dotbot` with the path to the Dotbot submodule; be sure to commit your changes before running `./install`, otherwise the old version of Dotbot will be checked out by the install script. If using a subrepo, run `git fetch && git checkout origin/master` in the Dotbot directory. If you prefer, you can install Dotbot from [PyPI] and call it as a command-line program: ```bash pip install dotbot touch install.conf.yaml ``` In this case, rather than running `./install`, you can invoke Dotbot with `dotbot -c `. ### Full Example Here's an example of a complete configuration. The conventional name for the configuration file is `install.conf.yaml`. ```yaml - defaults: link: relink: true - clean: ['~'] - link: ~/.dotfiles: '' ~/.tmux.conf: tmux.conf ~/.vim: vim ~/.vimrc: vimrc - shell: - [git submodule update --init --recursive, Installing submodules] ``` The configuration file is typically written in YAML, but it can also be written in JSON (which is a subset of YAML). [Here][json-equivalent] is the JSON [equivalent][json2yaml] of the YAML configuration given above. JSON configuration files are conventionally named `install.conf.json`. Configuration ------------- Dotbot uses YAML or JSON-formatted configuration files to let you specify how to set up your dotfiles. Currently, Dotbot knows how to [link](#link) files and folders, execute [shell](#shell) commands, and [clean](#clean) directories of broken symbolic links. Dotbot also supports user [plugins](#plugins) for custom commands. **Ideally, bootstrap configurations should be idempotent. That is, the installer should be able to be run multiple times without causing any problems.** This makes a lot of things easier to do (in particular, syncing updates between machines becomes really easy). Dotbot configuration files are arrays of tasks, where each task is a dictionary that contains a command name mapping to data for that command. Tasks are run in the order in which they are specified. Commands within a task do not have a defined ordering. When writing nested constructs, keep in mind that YAML is whitespace-sensitive. Following the formatting used in the examples is a good idea. If a YAML configuration file is not behaving as you expect, try inspecting the [equivalent JSON][json2yaml] and check that it is correct. Also, note that `~` in YAML is the same as `null` in JSON. If you want a single character string containing a tilde, make sure to enclose it in quotes: `'~'` ### Link Link commands specify how files and directories should be symbolically linked. If desired, items can be specified to be forcibly linked, overwriting existing files if necessary. Environment variables in paths are automatically expanded. #### Format Link commands are specified as a dictionary mapping targets to source locations. Source locations are specified relative to the base directory (that is specified when running the installer). If linking directories, *do not* include a trailing slash. Link commands support an (optional) extended configuration. In this type of configuration, instead of specifying source locations directly, targets are mapped to extended configuration dictionaries. Available extended configuration parameters: | Link Option | Explanation | | -- | -- | | `path` | The target for the symlink, the same as in the shortcut syntax (default:null, automatic (see below)) | | `create` | When true, create parent directories to the link as needed. (default:false) | | `relink` | Removes the old target if it's a symlink (default:false) | | `force` | Force removes the old target, file or folder, and forces a new link (default:false) | | `relative` | Use a relative path when creating the symlink (default:false, absolute links) | | `glob` | Treat a `*` character as a wildcard, and perform link operations on all of those matches (default:false) | | `if` | Execute this in your `$SHELL` and only link if it is successful. | #### Example ```yaml - link: ~/.config/terminator: create: true path: config/terminator ~/.vim: vim ~/.vimrc: relink: true path: vimrc ~/.zshrc: force: true path: zshrc ``` If the source location is omitted or set to `null`, Dotbot will use the basename of the destination, with a leading `.` stripped if present. This makes the following config files equivalent: ```yaml - link: ~/bin/ack: ack ~/.vim: vim ~/.vimrc: relink: true path: vimrc ~/.zshrc: force: true path: zshrc ~/.config/: glob: true path: config/* relink: true ``` ```yaml - link: ~/bin/ack: ~/.vim: ~/.vimrc: relink: true ~/.zshrc: force: true ~/.config/: glob: true path: config/* relink: true ``` ### Shell Shell commands specify shell commands to be run. Shell commands are run in the base directory (that is specified when running the installer). #### Format Shell commands can be specified in several different ways. The simplest way is just to specify a command as a string containing the command to be run. Another way is to specify a two element array where the first element is the shell command and the second is an optional human-readable description. Shell commands support an extended syntax as well, which provides more fine-grained control. A command can be specified as a dictionary that contains the command to be run, a description, whether to suppress outputting the command in the display via `quiet`, and whether `stdin`, `stdout`, and `stderr` are enabled. In this syntax, all keys are optional except for the command itself. #### Example ```yaml - shell: - mkdir -p ~/src - [mkdir -p ~/downloads, Creating downloads directory] - command: read var && echo Your variable is $var stdin: true stdout: true description: Reading and printing variable quiet: true - command: read fail stderr: true ``` ### Clean Clean commands specify directories that should be checked for dead symbolic links. These dead links are removed automatically. Only dead links that point to the dotfiles directory are removed unless the `force` option is set to `true`. #### Format Clean commands are specified as an array of directories to be cleaned. Clean commands support an extended configuration syntax. In this type of configuration, commands are specified as directory paths mapping to options. If the `force` option is set to `true`, dead links are removed even if they don't point to a file inside the dotfiles directory. #### Example ```yaml - clean: ['~'] - clean: ~/.config: force: true ``` ### Defaults Default options for plugins can be specified so that options don't have to be repeated many times. This can be very useful to use with the link command, for example. Defaults apply to all commands that follow setting the defaults. Defaults can be set multiple times; each change replaces the defaults with a new set of options. #### Format Defaults are specified as a dictionary mapping action names to settings, which are dictionaries from option names to values. #### Example ```yaml - defaults: link: create: true relink: true ``` ### Plugins Dotbot also supports custom directives implemented by plugins. Plugins are implemented as subclasses of `dotbot.Plugin`, so they must implement `can_handle()` and `handle()`. The `can_handle()` method should return `True` if the plugin can handle an action with the given name. The `handle()` method should do something and return whether or not it completed successfully. All built-in Dotbot directives are written as plugins that are loaded by default, so those can be used as a reference when writing custom plugins. Plugins are loaded using the `--plugin` and `--plugin-dir` options, using either absolute paths or paths relative to the base directory. It is recommended that these options are added directly to the `install` script. Wiki ---- Check out the [Dotbot wiki][wiki] for more information, tips and tricks, user-contributed plugins, and more.
