Automate deployment of dotfiles to local paths or remote hosts
dotlink is a simple script to automate deploying an arbitrary set of “dotfiles” from a repository to either a local path or even a remote host using ssh/scp.
dotlink does not manage the dotfiles themselves, but uses a simple text file mapping dotfile names in the repository to their ultimate location relative to the target path. This allows you to have files without the dot prefix, for instance, or avoid replicating deep directory structures to track a single file.
dotlink requires Python, either version 2.7 or versions 3.2 and newer. No external libraries are required.
To install dotlink system-wide or in a virtualenv:
# pip install dotlink
Or if you want to hack on dotlink a bit, clone the repo and run:
# python setup.py develop
You’ll first need to create a mapping file in the root of your dotfile
.dotfiles (or just
dotfiles), following this format:
- Each line contains the local repository filename, optionally followed by a colon and the target filename if different than the local filename.
- External dotfile mappings can be included using
#include "path/to/mapping", and the requested map will be loaded as well. The requested path can either be an explicit filename, or a directory containing a mapping named
- Comments are denoted by lines beginning with the
#symbol, and are ignored.
An example mapping might look like:
# the dotfiles to care about aliases: .alias .bashrc .profile: .profile htop: .config/htop/htoprc vim: .vim vimrc: .vimrc
# some external dotfile paths to include #include “repo2/dotfiles” #include “/full/patt/to/repo3/”
Once the mapping is in place, run dotlink, and tell it where your source repository is, as well as where you want it to deploy to:
$ dotlink [path/to/repository] [[[user@]host:]path/to/target]
The source path is optional; dotlink will assume it’s your current directory if
it finds a
.dotfiles mapping file unless you specify otherwise. The target
path is also optional, and assumed to be your local home directory.
Sources can include local paths or remote git repository URLs. Targets can also include local paths, or remote paths accessible via ssh by providing a hostname as well as username if different than your current login.
If you’d like to embed dotlink within your dotfile repository,
dotlink/dotlink.py is a self-contained script, specifically to allow for this
use case. Simply copy dotfile.py into your repository; it has no external
### remote sources
Sources can also point at remote locations, such as git repositories, and
dotlink will clone the remote data into a temporary path and then copy the
contents into the appropriate paths. dotlink will guess this if your source
path begins with “git://” or “git@”, but you can also use
--git to force this
for non-standard URLs. The following command will clone my public dotfile repo,
and install it to your home directory:
$ dotlink git://github.com/jreese/dotfiles
This is essentially equivalent to the following sequence of commands:
$ git clone git://github.com/jreese/dotfiles $ dotlink dotfiles $ rm -rf dotfiles
You can even combine remote sources with remote targets, to clone the dotfile repository locally, and then copy the dotfiles to the remote host via scp:
$ dotlink git://github.com/jreese/dotfiles jreese@devserver:
Some planned features and changes are:
- Add support for remote sources, like ssh/scp, as well as git repos or tarballs
- Generate mapping file from repository contents ?
