+
+While it may appear that there's an overwhelming amount of documentation and
+while the explanation of the concepts behind `vcsh` needs to touch a few gory
+details of `git` internals, getting started with `vcsh` is extremely simple.
+
+Let's say you want to version control your `vim` configuration:
+
+ vcsh init vim
+ vcsh vim add ~/.vimrc ~/.vim
+ vcsh vim commit -m 'Initial commit of my Vim configuration'
+ # optionally push your files to a remote
+ vcsh vim remote add origin <remote>
+ vcsh vim push -u origin master
+ # from now on you can push additional commits like this
+ vcsh vim push
+
+If all that looks a _lot_ like standard `git`, that's no coincidence; it's
+a design feature.
+
+
+# Introduction
+
+[vcsh][vcsh] allows you to maintain several Git repositories in one single
+directory. They all maintain their working trees without clobbering each other
+or interfering otherwise. By default, all Git repositories maintained via
+`vcsh` store the actual files in `$HOME` but you can override this setting if
+you want to.
+
+All this means that you can have one repository per application or application
+family, i.e. `zsh`, `vim`, `ssh`, etc. This, in turn, allows you to clone
+custom sets of configurations onto different machines or even for different
+users; picking and mixing which configurations you want to use where.
+For example, you may not need to have your `mplayer` configuration on a server
+or available to root and you may want to maintain different configuration for
+`ssh` on your personal and your work machines.
-* Mailing list: http://lists.madduck.net/listinfo/vcs-home
+A lot of modern UNIX-based systems offer packages for `vcsh`. In case yours
+does not read `INSTALL.md` for install instructions or `PACKAGING.md` to create
+a package, yourself. If you do end up packaging `vcsh` please let us know so we
+can give you your own packaging branch in the upstream repository.

-vcsh allows you to have several git repositories, all maintaining their working
-trees in $HOME without clobbering each other. That, in turn, means you can have
-one repository per config set (zsh, vim, ssh, etc), picking and choosing which
-configs you want to use on which machine.
-vcsh was designed with [mr] [1] in mind so you might want to install that, as
-well.
+# Usage Examples
-Read INSTALL.md for detailed setup instructions.
+There are three different ways to interact with `vcsh` repositories; this
+section will only show the simplest and easiest way.
-The following overview will try to give you an idea of the use cases and
-advantages of vcsh. See sections 3 and 4 for detailed instructions and
-examples.
+Certain more advanced use cases require the other two ways, but don't worry
+about this for now. If you never even bother playing with the other two
+modes you will still be fine.
-## 2.1 Talks ##
+`vcsh enter` and `vcsh run` will be covered in later sections.
-Some people found it useful to look at slides and videos explaining how vcsh works.

-## 3.1 Comparison to Other Solutions ##
+
+# Overview
+
+## From zero to vcsh
+
+You put a lot of effort into your configuration and want to both protect and
+distribute this configuration.
Most people who decide to put their dotfiles under version control start with a
-**single repository in $HOME**, adding all their dotfiles (and possibly more)
+single repository in `$HOME`, adding all their dotfiles (and possibly more)
to it. This works, of course, but can become a nuisance as soon as you try to
manage more than one host.
The next logical step is to create single-purpose repositories in, for example,
-~/.dotfiles and to create **symbolic links in $HOME**. This gives you the
+`~/.dotfiles` and to create symbolic links into `$HOME`. This gives you the
flexibility to check out only certain repositories on different hosts. The
downsides of this approach are the necessary manual steps of cloning and
-symlinking the individual repositories. It will probably become a nuisance when
-you try to manage more than two hosts.
+symlinking the individual repositories.
+
+`vcsh` takes this approach one step further. It enables single-purpose
+repositories and stores them in a hidden directory. However, it does not create
+symbolic links in `$HOME`; it puts the actual files right into `$HOME`.
+
+As `vcsh` allows you to put an arbitrary number of distinct repositories into
+your `$HOME`, you will end up with a lot of repositories very quickly.
-**vcsh** takes this second approach one step further. It expects
-**single-purpose repositories** and stores them in a hidden directory (similar
-to ~/.dotfiles). However, it does not create symbolic links in $HOME; it puts
-the **actual files right into $HOME**.
+`vcsh` was designed with [myrepos][myrepos], a tool to manage Multiple
+Repositories, in mind and the two integrate very nicely. The myrepos tool
+(`mr`) has native support for `vcsh` repositories and the configuration for
+myrepos is just another set of files that you cat track with `vcsh` like any
+other. This makes setting up any new machine a breeze. It can take literally
+less than five minutes to go from standard installation to fully set up system.
-Furthermore, by making use of [mr] [1], it makes it very easy to enable/disable
-and clone a large number of repositories. The use of mr is technically optional
-(see 4.3), but it will be an integral part of the proposed system that follows.
+We suggest using [myrepos][myrepos] to manage both `vcsh` and other repositories. The
+`mr` utility takes care of pulling in and pushing out new data for a variety of
+version control systems. While the use of myrepos is technically optional, it will
+be an integral part of the proposed system that follows.
-## 3.2 Default Directory Layout ##
+## Default Directory Layout
To illustrate, this is what a possible directory structure looks like.
|-- .mrconfig
`-- .mrtrust
-### available.d ###
+### available.d
-The files you see in $XDG\_CONFIG\_HOME/mr/available.d are mr configuration files
-that contain the commands to manage (checkout, update etc.) a single
-repository. vcsh repo configs end in .vcsh, git configs end in .git, etc. This
-is optional and your preference. For example, this is what a zsh.vcsh
-with read-only access to my zshrc repo looks likes. I.e. in this specific
-example, push can not work as you will be using the author's repository. This
-is for demonstration, only. Of course, you are more than welcome to clone from
-this repository and fork your own.

checkout = vcsh clone 'git://github.com/RichiH/zshrc.git' zsh

- push = vcsh run zsh git push
- status = vcsh run zsh git status
- gc = vcsh run zsh git gc
+ update = vcsh zsh pull
+ push = vcsh zsh push
+ status = vcsh zsh status
+ gc = vcsh zsh gc
-### config.d ###
+### config.d
$XDG\_CONFIG\_HOME/mr/available.d contains *all available* repositories. Only
-files/links present in mr/config.d, however, will be used by mr. That means
+files/links present in mr/config.d, however, will be used by myrepos. That means
that in this example, only the zsh, gitconfigs, tmux and vim repositories will
be checked out. A simple `mr update` run in $HOME will clone or update those
four repositories listed in config.d.
-### ~/.mrconfig ###
+### ~/.mrconfig
Finally, ~/.mrconfig will tie together all those single files which will allow
you to conveniently run `mr up` etc. to manage all repositories. It looks like
this:
[DEFAULT]
- jobs = 5
- # Use if your mr does not have vcsh support in mainline, yet
- include = cat /usr/share/mr/vcsh
include = cat ${XDG_CONFIG_HOME:-$HOME/.config}/mr/config.d/*
-### repo.d ###
+### repo.d
$XDG\_CONFIG\_HOME/vcsh/repo.d is the directory where all git repositories which
are under vcsh's control are located. Since their working trees are configured
to be in $HOME, the files contained in those repositories will be put in $HOME
directly.
-Of course, [mr] [1] will work with this layout if configured according to this
-document (see above).
+
+Of course, [myrepos][myrepos] will work with this layout if configured according to
+this document (see above).
vcsh will check if any file it would want to create exists. If it exists, vcsh
will throw a warning and exit. Move away your old config and try again.
Optionally, merge your local and your global configs afterwards and push with
-`vcsh run foo git push`.
+`vcsh foo push`.

+## Moving into a New Host
To illustrate further, the following steps could move your desired
configuration to a new host.

+1. Clone the myrepos repository (containing available.d, config.d etc.); for
example: `vcsh clone git://github.com/RichiH/vcsh_mr_template.git mr`
2. Choose your repositories by linking them in config.d (or go with the default
you may have already configured by adding symlinks to git).
-3. Make sure the line 'include = cat /usr/share/mr/vcsh' in .mrconfig points
- to an existing file
-4. Run mr to clone the repositories: `cd; mr update`.
-5. Done.

+4. Done.
Hopefully the above could help explain how this approach saves time by
1. making it easy to manage, clone and update a large number of repositories
- (thanks to mr) and
+ (thanks to myrepos) and
2. making it unnecessary to create symbolic links in $HOME (thanks to vcsh).

Make sure none of the following files and directories exist for your test
(user). If they do, move them away for now:
All of the files are part of the template repository, the directory is where
the template will be stored.
- apt-get install mr
+### Install vcsh
-#### 4.1.2 Install vcsh ####
+#### Debian
-#### 4.1.2.1 Debian ####
+If you are using Debian Squeeze, you will need to enable backports and the
+package name for myrepos will be 'mr'.
-If you are using Debian Squeeze, you will need to enable backports
+From Wheezy onwards, you can install both directly:
- apt-get install vcsh
+ apt-get install myrepos vcsh
-#### 4.1.2.2 Arch Linux ####
+#### Gentoo
-vcsh is availabe via [AUR](https://aur.archlinux.org/packages.php?ID=54164)
-and further documentation about the use of AUR is available
-[on Arch's wiki](https://wiki.archlinux.org/index.php/Arch_User_Repository).
+To install vcsh in Gentoo Linux just give the following command as root:
- cd /var/abs/local/
- wget https://aur.archlinux.org/packages/vc/vcsh-git/vcsh-git.tar.gz
- tar xfz vcsh-git.tar.gz
- cd vcsh-git
- makepkg -s
- pacman -U vcsh*.pkg.tar.xz
+ emerge dev-vcs/vcsh
-#### 4.1.2.3 From source ####
+Note the portage package for myrepos still has the old project name:
-If your version of mr is older than version 1.07, make sure to put
+ emerge dev-vcs/mr
- include = cat /usr/share/mr/vcsh
+#### Arch Linux
+
+vcsh is available via this [AUR](https://aur.archlinux.org/packages/vcsh/)
+package. Likewise myrepos is available [here](https://aur.archlinux.org/packages/myrepos/).
+You may install both useing your favorite AUR helper. e.g. with yaourt:
-into your .mrconfig .
+ yaourt -Sya myrepos vcsh
+
+Or you can do it yourself manually using the documentation on installing AUR packages
+[on Arch's wiki](https://wiki.archlinux.org/index.php/Arch_User_Repository#Installing_packages).
+
+If you prefer to use the devel package that installs the git HEAD version it
+is available [here](https://aur.archlinux.org/packages/vcsh-git/).
+
+#### Mac OSX
+
+Formulas are available for vcsh as well as git and myrepos through [homebrew](http://brew.sh). The
+vcsh formula is set to depend on myrepos, so you only need one install command:
+
+ brew install vcsh
+
+#### From source
+
+To install the latest version from git:
# choose a location for your checkout
- cd $HOME
mkdir -p ~/work/git
+ cd ~/work/git
git clone git://github.com/RichiH/vcsh.git
cd vcsh
- ln -s vcsh /usr/local/bin # or add it to your PATH
- cd
+ sudo ln -s vcsh /usr/local/bin # or add it to your PATH
+
+For myrepos:
+
+ # use checkout location from above
+ cd ~/work/git
+ git clone git://myrepos.branchable.com/ myrepos
+ cd myrepos
+ make install

Now, it's time to edit the template config and fill it with your own remotes:
And then create your own stuff:
vcsh init foo
- vcsh run foo git add -f bar baz quux
- vcsh run foo git remote add origin git://quuux
- vcsh run foo git commit
- vcsh run foo git push
+ vcsh foo add bar baz quux

cp $XDG_CONFIG_HOME/mr/available.d/mr.vcsh $XDG_CONFIG_HOME/mr/available.d/foo.vcsh
vim $XDG_CONFIG_HOME/mr/available.d/foo.vcsh # add your own repo
Done!
