# Dotfile Management Made Easy

`dotfiles` is a tool to make managing your dotfile symlinks in `$HOME`
easy, allowing you to keep all your dotfiles in a single directory.

Hosting is up to you. You can use a VCS like git, Dropbox, or even rsync
to distribute your dotfiles repository across multiple hosts.

One or more repositories can be specified at runtime or with an
environment variable, so you can manage multiple repositories without
hassle.

You can choose to have your dotfiles linked with symbolic links or
copied into place, either way `dotfiles` will keep track of what's
missing and what's different.

`dotfiles` is unique in the way it manages links and copies.  The entire
directory structure leading to a file is preserved and only the file
itself is considered managed.  This allows managed and unmanaged files
to live next to each other without needing to specify complicated ignore
rules.  If you want to be less selective, you can specify a directory
that contains several files, and `dotfiles` will grab all of them in
whatever hierarchy they exist.

## Upgrading From An Old Version

Much has changed in the most recent version.  If you're considering
upgrading it's probably best to unlink everything and start with an
empty repository.  This can be done with the following command:

    $ dotfiles --unsync

## Installation

There are a few ways to install this thing.  The easiest way is using
whatever package manager is available on your OS if there is an official
package available.

If not, you can install globally with pip:

    $ pip install dotfiles

If you don't want to or don't have permission to install it globally,
you can install it just for your user:

    $ pip install --user dotfiles

If you just want to run it directly from the source tree, you can do
that too:

    $ git clone https://github.com/jbernard/dotfiles
    $ cd dotfiles
    $ git submodule update --init
    $ ./bin/dotfiles --help

Note: the source tree example above will run whatever code has been
committed to your current checkout, whereas pip will fetch the latest
official version from pypi.  This might be what you want, but you should
be aware.

## Getting Help And Discovering Commands

`dotfiles` uses click for its CLI interface, so every subcommand accepts
the `--help` flag to offer additional information on what is available.
The aim is for this information to be sufficient for use.  At some point
I'll write a manpage, but do file a bug if any of the usage information
is inaccurate or misleading.

## Interface

`-a, --add <file...>`
    Add dotfile(s) to the repository.

`-c, --check`
    Check for missing or unsynced dotfiles.

`-l, --list`
    List currently managed dotfiles, one per line.

`-r, --remove <file...>`
    Remove dotfile(s) from the repository.

`-s, --sync [file...]`
    Update dotfile symlinks. You can overwrite colliding files with `-f` or
    `--force`.  All dotfiles are assumed if you do not specify any files to
    this command.

`-m, --move <path>`
    Move dotfiles repository to another location, updating all symlinks in the
    process.

For all commands you can use the `--dry-run` option, which will print actions
and won't modify anything on your drive.

## Installation

To install dotfiles, simply:

    $ pip install dotfiles

Or, if you absolutely must:

    $ easy_install dotfiles

But, you really shouldn't do that.

If you want to work with the latest version, you can install it from `the
repository`_:

    $ git clone https://github.com/jbernard/dotfiles
    $ cd dotfiles
    $ ./bin/dotfiles --help

## Examples

To install your dotfiles on a new machine, you might do this:

    $ git clone https://github.com/me/my-dotfiles Dotfiles
    $ dotfiles --sync

To add '~/.vimrc' to your repository:

    $ dotfiles --add ~/.vimrc     (relative paths work also)

To make it available to all your hosts:

    $ cd ~/Dotfiles
    $ git add vimrc
    $ git commit -m "Added vimrc, welcome aboard!"
    $ git push

You get the idea. Type `dotfiles --help` to see the available options.

## Configuration

You can choose to create a configuration file to store personal customizations.
By default, `dotfiles` will look for `~/.dotfilesrc`. You can change this
with the `-C` flag. An example configuration file might look like:

    [dotfiles]
    repository = ~/Dotfiles
    ignore = [
        '.git',
        '.gitignore',
        '*.swp']
    externals = {
        '.bzr.log':     '/dev/null',
        '.uml':         '/tmp'}

You can also store your configuration file inside your repository. Put your
settings in `.dotfilesrc` at the root of your repository and `dotfiles` will
find it. Note that `ignore` and `externals` are appended to any values
previously discovered.

Prefixes
--------

Dotfiles are stored in the repository with no prefix by default. So,
`~/.bashrc` will link to `~/Dotfiles/bashrc`. If your files already have a
prefix, `.` is common, but I've also seen `_`, then you can specify this
in the configuration file and `dotfiles` will do the right thing. An example
configuration in `~/.dotfilesrc` might look like:

    [dotfiles]
    prefix = .

Externals
---------

You may want to link some dotfiles to external locations. For example, `bzr`
writes debug information to `~/.bzr.log` and there is no easy way to disable
it. For that, I link `~/.bzr.log` to `/dev/null`. Since `/dev/null` is
not within the repository, this is called an external. You can have as many of
these as you like. The list of externals is specified in the configuration
file:

    [dotfiles]
    externals = {
        '.bzr.log':     '/dev/null',
        '.adobe':       '/tmp',
        '.macromedia':  '/tmp'}

Ignores
-------

If you're using a VCS to manage your repository of dotfiles, you'll want to
tell `dotfiles` to ignore VCS-related files. For example, I use `git`, so
I have the following in my `~/.dotfilesrc`:

    [dotfiles]
    ignore = [
         '.git',
         '.gitignore',
         '*.swp']

Any file you list in `ignore` will be skipped. The `ignore` option supports
glob file patterns.

Packages
--------

Many programs store their configuration in `~/.config`. It's quite cluttered
and you probably don't want to keep all its content in your repository. For this
situation you can use the `packages` setting:

    [dotfiles]
    packages = ['config']

This tells `dotfiles` that the contents of the `config` subdirectory of
your repository must be symlinked to `~/.config`. If for example you have a
directory `config/awesome` in your repository, it will be symlinked to
`~/.config/awesome`.

This feature allows one additional level of nesting, but further subdirectories
are not eligible for being a package.  For example, `config` is valid, but
`config/transmission` is not valid.  Arbitrary nesting is a feature under
current consideration.

At the moment, packages can not be added or removed through the command line
interface.  They must be constructed and configured manually.  Once this is
done, `sync`, `list`, `check`, and `move` will do the right thing.
Support for `add` and `remove` is a current TODO item.

Contribute
----------

If you'd like to contribute, simply fork [the
repository](https://github.com/jbernard/dotfiles), commit your changes, make
sure tests pass, and send a pull request. Go ahead and add yourself to
[AUTHORS](AUTHORS.md) or I'll do it when I merge your changes.
