-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.

+
+
+# 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.
+
+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.
+
+## Talks
+
+Some people found it useful to look at slides and videos explaining how `vcsh`
+works instead of working through the docs.
+All slides, videos, and further information can be found
+[on the author's talk page][talks].
+
+
+# Usage Examples
+
+There are three different ways to interact with `vcsh` repositories; this
+section will only show the simplest and easiest way.
+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.
+`vcsh enter` and `vcsh run` will be covered in later sections.
+
+

+
+# 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`.
-**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 $HOME**.
+As `vcsh` allows you to put an arbitrary number of distinct repositories into
+your `$HOME`, you will end up with a lot of repositories very quickly.
-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 3.4), but it will be an integral part of the proposed system that follows.
+To manage both `vcsh` and other repositories, we suggest using [mr](mr). `mr`
+takes care of pulling in and pushing out new data for a variety of version
+control systems.
-## 2.2 Default Directory Layout ##
+`vcsh` was designed with [mr][mr], a tool to manage Multiple Repositories, in
+mind and the two integrate very nicely. `mr` has native support for `vcsh`
+repositories and to `vcsh`, `mr` is just another configuration to track.
+This make setting up any new machine a breeze. It takes literally less than
+five minutes to go from standard installation to fully set up system
+
+This is where `mr` comes in. While the use of `mr` is technically
+optional, but it will be an integral part of the proposed system that follows.
+
+## Default Directory Layout
To illustrate, this is what a possible directory structure looks like.
$HOME
- |-- .config
+ |-- $XDG_CONFIG_HOME (defaults to $HOME/.config)
| |-- mr
| | |-- available.d
| | | |-- zsh.vcsh
| | |-- tmux.vcsh -> ../available.d/tmux.vcsh
| | `-- vim.vcsh -> ../available.d/vim.vcsh
| `-- vcsh
+ | |-- config
| `-- repo.d
| |-- zsh.git -----------+
| |-- gitconfigs.git |
| `-- vim.git |
|-- [...] |
|-- .zshrc <----------------------+
- |-- .gitignore
+ |-- .gitignore.d
+ | `-- zsh
|-- .mrconfig
`-- .mrtrust
-### available.d ###
+### available.d
-The files you see in ~/.config/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.mrconfig with read-only
-access to my zshrc repo looks likes. I.e. in this specific example, push can
-not work.
+The files you see in $XDG\_CONFIG\_HOME/mr/available.d are mr configuration files
+that contain the commands to manage (checkout, update etc.) a single
+repository. vcsh repo configs end in .vcsh, git configs end in .git, etc. This
+is optional and your preference. For example, this is what a zsh.vcsh
+with read-only access to my zshrc repo looks likes. I.e. in this specific
+example, push can not work as you will be using the author's repository. This
+is for demonstration, only. Of course, you are more than welcome to clone from
+this repository and fork your own.
- [$HOME/.config/vcsh/repo.d/zsh.git]
+ [$XDG_CONFIG_HOME/vcsh/repo.d/zsh.git]
checkout = vcsh clone 'git://github.com/RichiH/zshrc.git' zsh
- update = vcsh run zsh git pull
- push = vcsh run zsh git push
- status = vcsh run zsh git status
- gc = vcsh run zsh git gc
+ update = vcsh zsh pull
+ push = vcsh zsh push
+ status = vcsh zsh status
+ gc = vcsh zsh gc
-### config.d ###
+### config.d
-~/.config/mr/available.d contains *all available* repositories. Only
+$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
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
- include = cat ~/.config/mr/config.d/*
-
-### repo.d ###
+ include = cat ${XDG_CONFIG_HOME:-$HOME/.config}/mr/config.d/*
-~/.config/vcsh/repo.d is the directory into which vcsh clones the git
-repositories. Since their working trees are configured to be in $HOME, the
-files contained in those repositories will be put in $HOME directly (see .zshrc
-above).
+### repo.d
+$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] [mr] 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`.
-## 2.3 Moving into a New Host ##
+## Moving into a New Host
To illustrate further, the following steps could move your desired
configuration to a new host.
1. Clone the mr repository (containing available.d, config.d etc.); for
- example: `vcsh clone git://github.com/RichiH/vcsh_mr_template.git`
+ 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. Run mr to clone the repositories: `cd; mr update`.
If you want to give vcsh a try, follow the instructions below.

apt-get install mr
-#### 3.1.2 Clone the Template ####
+### Install vcsh
+
+#### Debian
+If you are using Debian Squeeze, you will need to enable backports.
+From Wheezy onwards, you can install it directly:
+
+ apt-get install vcsh
+
+#### Gentoo
+
+To install vcsh in Gentoo Linux just give the following command as root:
+
+ emerge dev-vcs/vcsh
+
+#### Arch Linux
+
+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).
+
+ 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
+
+#### From source
+
+ # choose a location for your checkout
mkdir -p ~/work/git
- cd !$
- git clone git://github.com/RichiH/vcsh.git vcsh
+ 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
+ sudo ln -s vcsh /usr/local/bin # or add it to your PATH
cd
- vcsh clone git://github.com/RichiH/vcsh_mr_template.git mr.vcsh
-#### 3.1.3 Enable Your Test Repository ####

mv ~/.zsh ~/zsh.bak
mv ~/.zshrc ~/zshrc.bak
- cd ~/.config/mr/config.d/
+ cd $XDG_CONFIG_HOME/mr/config.d/
ln -s ../available.d/zsh.vcsh . # link, and thereby enable, the zsh repository
cd
mr up
-#### 3.1.4 Set Up Your Own Repositories ####
+#### Set Up Your Own Repositories
Now, it's time to edit the template config and fill it with your own remotes:
- vim .config/mr/available.d/mr.vcsh
- vim .config/mr/available.d/zsh.vcsh
+ vim $XDG_CONFIG_HOME/mr/available.d/mr.vcsh
+ vim $XDG_CONFIG_HOME/mr/available.d/zsh.vcsh
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
+ vcsh foo remote add origin git://quuux
+ vcsh foo commit
+ vcsh foo push
- cp .config/mr/available.d/mr.vcsh .config/mr/available.d/foo.vcsh
- vim .config/mr/available.d/foo.vcsh # add your own repo
+ 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!
-### 3.2 The Steal-from-Template Way ###
+### The Steal-from-Template Way
You're welcome to clone the example repository:
- git clone git://github.com/RichiH/vcsh_mr_template.git
+ vcsh clone git://github.com/RichiH/vcsh_mr_template.git mr
+ # make sure 'include = cat /usr/share/mr/vcsh' points to an exiting file
+ vim .mrconfig
Look around in the clone. It should be reasonably simple to understand. If not,
poke me, RichiH, on Freenode (query) or OFTC (#vcs-home).
-### 3.3 The Manual Way ###
+### The Manual Way
This is how my old setup procedure looked like. Adapt it to your own style or
copy mine verbatim, either is fine.
Grab my mr config. see below for details on how I set this up
vcsh clone ssh://<remote>/mr.git
- cd ~/.config/mr/config.d/
+ cd $XDG_CONFIG_HOME/mr/config.d/
ln -s ../available.d/* .
~ % cat ~/.mrconfig

After you have made some changes, for which you would normally use `git add`

-
-By the way, you'll have to use -f/--force flag with git-add because all files

repositories by running the necessary vcsh commands for you. You may choose not
to use mr, in which case you will have to run those commands manually or by
other means.
-#### A Few Examples ####
To initialize a new repository: `vcsh init zsh`
To interact with a repository, use the regular Git commands, but prepend them
with `vcsh run $repository_name`. For example:
- vcsh run zsh git status
- vcsh run zsh git add -f .zshrc
- vcsh run zsh git commit
+ vcsh zsh status
+ vcsh zsh add .zshrc
+ vcsh zsh commit
Obviously, without mr keeping repositories up-to-date, it will have to be done
manually. Alternatively, you could try something like this:
vcsh run $repo git pull;
done
