DOTDROP

Save your dotfiles once, deploy them everywhere

Dotdrop makes the management of dotfiles between different hosts easy. It allows to store your dotfiles on git and automagically deploy different versions on different setups.

For example you can have a set of dotfiles for your home laptop and a different set for your office desktop. Those sets may overlap and different versions of the same dotfile can be deployed on different predefined profiles. Another use case is when you have a main set of dotfiles for your everyday's host and a sub-set you only need to deploy to temporary hosts (cloud VM, etc) that may be using a slightly different version of some of the dotfiles.

Features:

Sync once every dotfile on git for different usages
Allow dotfiles templating by leveraging jinja2
Comparison between local and stored dotfiles
Handling multiple profiles with different sets of dotfiles
Easy import dotfiles
Handle files and directories
Associate an action to the deployment of specific dotfiles
Associate transformations that allow to store encrypted dotfiles

Check also the blog post, the example or how people are using dotdrop for more.

Quick start:

mkdir dotfiles && cd dotfiles
git init
git submodule add https://github.com/deadc0de6/dotdrop.git
./dotdrop/bootstrap.sh
./dotdrop.sh --help

Why dotdrop ?

There exist many tools to manage dotfiles however not many allow to deploy different versions of the same dotfile on different hosts. Moreover dotdrop allows to specify the set of dotfiles that need to be deployed on a specific profile.

See the example for a concrete example on why dotdrop rocks.

Installation

There's two ways of installing and using dotdrop, either as a submodule to your dotfiles git tree or system-wide with pypi.

Having dotdrop as a submodule guarantees that anywhere your are cloning your dotfiles git tree from you'll have dotdrop shipped with it. It is the recommended way.

Dotdrop is also available on aur:

stable: https://aur.archlinux.org/packages/dotdrop/
git version: https://aur.archlinux.org/packages/dotdrop-git/

As a submodule

The following will create a repository for your dotfiles and keep dotdrop as a submodules:

$ mkdir dotfiles; cd dotfiles
$ git init
$ git submodule add https://github.com/deadc0de6/dotdrop.git
$ sudo pip3 install -r dotdrop/requirements.txt
$ ./dotdrop/bootstrap.sh
$ ./dotdrop.sh --help

Install the requirements with:

$ sudo pip3 install -r dotdrop/requirements.txt

For MacOS users, make sure to install realpath through homebrew (part of coreutils).

Using this solution will need you to work with dotdrop by using the generated script dotdrop.sh at the root of your dotfiles repository.

Finally import your dotfiles as described below.

With pypi

Start by installing dotdrop

$ sudo pip3 install dotdrop

And then create a repository for your dotfiles

$ mkdir dotfiles; cd dotfiles
$ git init

To avoid the need to provide the config file path to dotdrop each time it is called, you can create an alias:

alias dotdrop='dotdrop --cfg=<path-to-your-config.yaml>'

Replace any call to dotdrop.sh in the documentation below by dotdrop if using the pypi solution.

Finally import your dotfiles as described below.

Usage

If starting fresh, the import command of dotdrop allows to easily and quickly get a running setup.

Install dotdrop on one of your host and then import any dotfiles you want dotdrop to manage (be it a file or a directory):

$ dotdrop.sh import ~/.vimrc ~/.xinitrc

Dotdrop does two things:

Copy the dotfiles in the dotfiles directory
Create the entries in the config.yaml file

Commit and push your changes.

Then go to another host where your dotfiles need to be managed as well, clone the previously setup git tree and compare local dotfiles with the ones stored by dotdrop:

$ dotdrop.sh list
$ dotdrop.sh compare --profile=<other-host-profile>

Then adapt any dotfile using the template feature and set a new profile for the current host by simply adding lines in the config files, for example:

...
profiles:
  host1:
    dotfiles:
    - f_vimrc
    - f_xinitrc
  host2:
    dotfiles:
    - f_vimrc
...

When done, you can install your dotfiles using

$ dotdrop.sh install

That's it, a single repository with all your dotfiles for your different hosts.

For additional usage see the help:

$ dotdrop.sh --help

Usage:
  dotdrop install   [-fndV] [-c <path>] [-p <profile>]
  dotdrop import    [-ldV]  [-c <path>] [-p <profile>] <paths>...
  dotdrop compare   [-V]    [-c <path>] [-p <profile>]

  dotdrop update    [-fdV]  [-c <path>] <path>
  dotdrop listfiles [-V]    [-c <path>] [-p <profile>]
  dotdrop list      [-V]    [-c <path>]
  dotdrop --help
  dotdrop --version

Options:
  -p --profile=<profile>  Specify the profile to use [default: carbon].
  -c --cfg=<path>         Path to the config [default: config.yaml].
  --files=<files>         Comma separated list of files to compare.
  -o --dopts=<opts>       Diff options [default: ].
  -n --nodiff             Do not diff when installing.
  -l --link               Import and link.
  -f --force              Do not warn if exists.
  -V --verbose            Be verbose.
  -d --dry                Dry run.
  -v --version            Show version.
  -h --help               Show this screen.

For easy deployment the default profile used by dotdrop reflects the hostname of the host on which it runs.

Install dotfiles

Simply run

$ dotdrop.sh install

Use the --profile switch to specify a profile if not using the host's hostname.

Compare dotfiles

Compare local dotfiles with dotdrop's defined ones:

$ dotdrop.sh compare

The diffing is done by diff in the backend, one can provide specific options to diff using the -o switch.

Import dotfiles

Dotdrop allows to import dotfiles directly from the filesystem. It will copy the dotfile and update the config file automatically.

For example to import ~/.xinitrc

$ dotdrop.sh import ~/.xinitrc

List profiles

$ dotdrop.sh list

Dotdrop allows to choose which profile to use with the --profile switch if you use something else than the default (the hostname).

List dotfiles

The following command lists the different dotfiles configured for a specific profile:

$ dotdrop.sh listfiles --profile=<some-profile>

For example:

Dotfile(s) for profile "some-profile":

f_vimrc (file: "vimrc", link: False)
	-> ~/.vimrc
f_dunstrc (file: "config/dunst/dunstrc", link: False)
	-> ~/.config/dunst/dunstrc

Use actions

It is sometimes useful to execute some kind of action when deploying a dotfile. For example let's consider Vundle is used to manage vim's plugins, the following action could be set to update and install the plugins when vimrc is deployed:

actions:
  vundle: vim +VundleClean! +VundleInstall +VundleInstall! +qall
config:
  backup: true
  create: true
  dotpath: dotfiles
dotfiles:
  f_vimrc:
    dst: ~/.vimrc
    src: vimrc
    actions:
      - vundle
profiles:
  home:
    dotfiles:
    - f_vimrc

Thus when f_vimrc is installed, the command vim +VundleClean! +VundleInstall +VundleInstall! +qall will be executed.

Use transformations

Transformation actions are used to transform a dotfile before it is installed. They work like actions but are executed before the dotfile is installed to transform the source.

Transformation commands have two arguments:

{0} will be replaced with the dotfile to process
{1} will be replaced with a temporary file to store the result of the transformation

A typical use-case for transformations is when the dotfile needs to be stored encrypted.

Here's an example of part of a config file to use gpg encrypted dotfiles:

dotfiles:
  f_secret:
    dst: ~/.secret
    src: secret
    trans:
      - gpg
trans:
  gpg: gpg2 -q --for-your-eyes-only --no-tty -d {0} > {1}

The above config allows to store the dotfile ~/.secret encrypted in the dotfiles directory and uses gpg to decrypt it when install is run.

Here's how to deploy the above solution:

import the clear dotfile (creates the correct entries in the config file)

./dotdrop.sh import ~/.secret

encrypt the original dotfile

<some-gpg-command> ~/.secret

overwrite the dotfile with the encrypted version

cp <encrypted-version-of-secret> dotfiles/secret

edit the config file and add the transformation to the dotfile
commit and push the changes

Note that transformations cannot be used if the dotfiles is to be linked (link: true) and compare won't work on dotfiles using transformations.

Update dotdrop

If used as a submodule, update it with

$ git submodule foreach git pull origin master
$ git add dotdrop
$ git commit -m 'update dotdrop'
$ git push

Through pypi:

$ sudo pip3 install dotdrop --upgrade

Update dotfiles

Dotfiles managed by dotdrop can be updated using the update command. There are two cases:

the dotfile doesn't use templating: the new version of the dotfile is copied to the dotfiles directory and overwrites the old version. If git is used to version the dotfiles stored by dotdrop, the git command diff can be used to view the changes.
the dotfile uses templating: the dotfile must be manually updated, the use of the dotdrop command compare can be helpful to identify the changes to apply to the template.

$ dotdrop.sh update ~/.vimrc

Store sensitive dotfiles

Two solutions exist, the first one using an unversioned file (see Environment variables) and the second using transformations (see Transformations).

Config

The config file (defaults to config.yaml) is a yaml file containing the following entries:

config entry: contains settings for the deployment
- backup: create a backup of the dotfile in case it differs from the one that will be installed by dotdrop
- create: create directory hierarchy when installing dotfiles if it doesn't exist
- dotpath: path to the directory containing the dotfiles to be managed by dotdrop (absolute path or relative to the config file location)
dotfiles entry: a list of dotfiles
- When link is true, dotdrop will create a symlink instead of copying. Template generation (as in template) is not supported when link is true.
- actions contains a list of action keys that need to be defined in the actions entry below.
- trans contains a list of transformation keys that need to be defined in the trans entry below.

  <dotfile-key-name>:
    dst: <where-this-file-is-deployed>
    src: <filename-within-the-dotpath>
    # Optional
    link: <true|false>
    actions:
      - <action-key>
    trans:
      - <transformation-key>

profiles entry: a list of profiles with the different dotfiles that need to be managed
- dotfiles: the dotfiles associated to this profile
- include: include all dotfiles from another profile (optional)

  <some-name-usually-the-hostname>:
    dotfiles:
    - <some-dotfile-key-name-defined-above>
    - <some-other-dotfile-key-name>
    - ...
    # Optional
    include:
    - <some-other-profile>
    - ...

actions entry: a list of action

  <action-key>: <command-to-execute>

trans entry: a list of transformations

  <trans-key>: <command-to-execute>

All dotfiles for a profile

To use all defined dotfiles for a profile, simply use the keyword ALL.

For example:

dotfiles:
  f_xinitrc:
    dst: ~/.xinitrc
    src: xinitrc
  f_vimrc:
    dst: ~/.vimrc
    src: vimrc
profiles:
  host1:
    dotfiles:
    - ALL
  host2:
    dotfiles:
    - f_vimrc

Include dotfiles from another profile

If one profile is using the entire set of another profile, one can use the include entry to avoid redundancy.

For example:

profiles:
  host1:
      dotfiles:
        - f_xinitrc
      include:
        - host2
  host2:
      dotfiles:
        - f_vimrc

Here profile host1 contains all the dotfiles defined for host2 plus f_xinitrc.

Template

Dotdrop leverage the power of jinja2 to handle the templating of dotfiles. See jinja2 template doc or the example section for more information on how to template your dotfiles.

Note that dotdrop uses different delimiters than jinja2's defaults:

block start = {%@@
block end = @@%}
variable start = {{@@
variable end = @@}}
comment start = {#@@
comment end = @@#}

Available variables

{{@@ profile @@}} contains the profile provided to dotdrop.
{{@@ env['MY_VAR'] @@}} contains environment variables (see Environment variables)

Environment variables

It's possible to access environment variables inside the templates. This feature can be used like this:

{{@@ env['MY_VAR'] @@}}

This allows for storing host-specific properties and/or secrets in environment variables.

You can have an .env file in the directory where your config.yaml lies:

## My variables for this host
var1="some value"
var2="some other value"

## Some secrets
pass="verysecurepassword"

Of course, this file should not be tracked by git (put it in your .gitignore).

Then you can invoke dotdrop with the help of an alias when using dotdrop as a submodule:

alias dotdrop='eval $(grep -v "^#" ~/dotfiles/.env) ~/dotfiles/dotdrop.sh'

When using dotdrop from pypi or aur, the absolute path to the binary should be used in the alias to avoid recursion issues

alias dotdrop='eval $(grep -v "^#" ~/dotfiles/.env) /usr/bin/dotdrop --cfg=~/dotfiles/config.yaml'

The above aliases load all the variables from ~/dotfiles/.env (while omitting lines starting with #) before calling dotdrop.

Example

Let's consider two hosts:

home: home computer with hostname home
office: office computer with hostname office

The home computer is running awesomeWM and the office computer bspwm. The .xinitrc file will therefore be different while still sharing some lines. Dotdrop allows to store only one single .xinitrc but to deploy different versions depending on where it is run from.

The following file is the dotfile stored in dotdrop containing jinja2 directives for the deployment based on the profile used.

Dotfile <dotpath>/xinitrc:

#!/bin/bash

# load Xresources
userresources=$HOME/.Xresources
if [ -f "$userresources" ]; then
      xrdb -merge "$userresources" &
fi

# launch the wm
{%@@ if profile == "home" @@%}
exec awesome
{%@@ elif profile == "office" @@%}
exec bspwm
{%@@ endif @@%}

The if branch will define which part is deployed based on the hostname of the host on which dotdrop is run from.

And here's how the config file looks like with this setup. Of course any combination of the dotfiles (different sets) can be done if more dotfiles have to be deployed.

config.yaml file:

config:
  backup: true
  create: true
  dotpath: dotfiles
dotfiles:
  f_xinitrc:
    dst: ~/.xinitrc
    src: xinitrc
profiles:
  home:
    dotfiles:
    - f_xinitrc
  office:
    dotfiles:
    - f_xinitrc

Installing the dotfiles (the --profile switch is not needed if the hostname matches the profile entry in the config file):

# on home computer
$ dotdrop.sh install --profile=home

# on office computer
$ dotdrop.sh install --profile=office

Comparing the dotfiles:

# on home computer
$ dotdrop.sh compare

# on office computer
$ dotdrop.sh compare

Migrate from submodule

Initially dotdrop was used as a submodule directly in the dotfiles git tree. That solution allows your dotfiles to be shipped along with the tool able to handle them. Dotdrop is however also directly available on pypi.

If you want to keep it as a submodule (recommended), simply do the following

$ cd <dotfiles-directory>

## get latest version of the submodule
$ git submodule foreach git pull origin master

## and stage the changes
$ git add dotdrop
$ git commit -m 'update dotdrop'

## update the bash script wrapper
$ ./dotdrop/bootstrap.sh

## and stage the change to the dotdrop.sh script
$ git add dotdrop.sh
$ git commit -m 'update dotdrop.sh'

## and finally push the changes upstream
$ git push

Otherwise, simply install it from pypi as explained above and get rid of the submodule as shown below:

move to the dotfiles directory where dotdrop is used as a submodule

$ cd <dotfiles-repository>

remove the entire submodule "dotdrop" section in .gitmodules
stage the changes

$ git add .gitmodules

remove the entire submodule "dotdrop" section in .git/config
remove the submodule

$ git rm --cached dotdrop

remove the submodule from .git

$ rm -rf .git/modules/dotdrop

commit the changes

$ git commit -m 'removing dotdrop submodule'

remove any remaining files from the dotdrop submodule

$ rm -rf dotdrop

remove dotdrop.sh

$ git rm dotdrop.sh
$ git commit -m 'remove dotdrop.sh script'

push upstream

$ git push
