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. - -Read INSTALL.md for detailed setup instructions. - -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. - -## 2.1 Talks ## - -People found it useful to look at slides and videos explaining how vcsh works. -They can all be found at [here](http://richardhartmann.de/talks/). - -# 3 Overview - -## 3.1 Comparison to Other Solutions ## - -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) -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 -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. - -**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**. - -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. - -## 3.2 Default Directory Layout ## - -To illustrate, this is what a possible directory structure looks like. - - $HOME - |-- $XDG_CONFIG_HOME (defaults to $HOME/.config) - | |-- mr - | | |-- available.d - | | | |-- zsh.vcsh - | | | |-- gitconfigs.vcsh - | | | |-- lftp.vcsh - | | | |-- offlineimap.vcsh - | | | |-- s3cmd.vcsh - | | | |-- tmux.vcsh - | | | |-- vim.vcsh - | | | |-- vimperator.vcsh - | | | `-- snippets.git - | | `-- config.d - | | |-- zsh.vcsh -> ../available.d/zsh.vcsh - | | |-- gitconfigs.vcsh -> ../available.d/gitconfigs.vcsh - | | |-- tmux.vcsh -> ../available.d/tmux.vcsh - | | `-- vim.vcsh -> ../available.d/vim.vcsh - | `-- vcsh - | |-- config - | `-- repo.d - | |-- zsh.git -----------+ - | |-- gitconfigs.git | - | |-- tmux.git | - | `-- vim.git | - |-- [...] | - |-- .zshrc <----------------------+ - |-- .gitignore.d - | `-- zsh - |-- .mrconfig - `-- .mrtrust - -### available.d ### - -The files you see in $XDG\_CONFIG\_HOME/mr/available.d are mr configuration files -that contain the commands to manage (checkout, update etc.) a single -repository. vcsh repo configs end in .vcsh, git configs end in .git, etc. This -is optional and your preference. For example, this is what a zsh.vcsh -with read-only access to my zshrc repo looks likes. I.e. in this specific -example, push can not work as you will be using the author's repository. This -is for demonstration, only. Of course, you are more than welcome to clone from -this repository and fork your own. - - [$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 - -### 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 -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 ### - -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 ### - -$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). - -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`. - -## 3.3 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 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. - -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 -2. making it unnecessary to create symbolic links in $HOME (thanks to vcsh). - -If you want to give vcsh a try, follow the instructions below. -# 4 Getting Started # +# 30 Second How-to -Below, you will find a few different methods for setting up vcsh: +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. -1. The Template Way -2. The Steal-from-Template Way -3.

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. - apt-get install mr +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. -#### 4.1.2 Clone the Template #### +A lot of modern UNIX-based systems offer packages for `vcsh`. In case yours +does not, read [INSTALL.md](doc/INSTALL.md) for install instructions or +[PACKAGING.md](doc/PACKAGING.md) to create a package yourself.

Once you are set up, just run: - - mr up - mr push - -Neat. - -### 5.1 Making Changes ### - -After you have made some changes, for which you would normally use `git add` -and `git commit`, use the vcsh wrapper (like above): - - vcsh run foo git add -f bar baz quux - vcsh run foo git commit - vcsh run foo git push - -By the way, you'll have to use -f/--force flag with git-add because all files -will be ignored by default. This is to show you only useful output when running -git-status. A fix for this problem is being worked on. - -### 5.3 Using vcsh without mr ### - -vcsh encourages you to use [mr] [1]. It helps you manage a large number of -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 clone a repository: `vcsh clone ssh:///zsh.git` - -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 +There are several ways to get in touch with the author and a small but committed +community around the general idea of version controlling your (digital) life. -Obviously, without mr keeping repositories up-to-date, it will have to be done -manually.
