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 into `$HOME`. This gives you the -flexibility to check out only certain repositories on different hosts. The -downsides of this approach are the necessary manual steps of cloning and -symlinking the individual repositories. - -`vcsh` takes this approach one step further. It enables single-purpose -repositories and stores them in a hidden directory. However, it does not create -symbolic links in `$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` 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. - -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. - -## 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 $XDG\_CONFIG\_HOME/mr/available.d are myrepos -configuration files that contain the commands to manage (checkout, update -etc.) a single repository. vcsh repo configs end in .vcsh, git configs end -in .git, etc. This is optional and your preference. For example, this is -what a zsh.vcsh with read-only access to my zshrc repo looks likes. I.e. in -this specific example, push can not work as you will be using the author's -repository. This is for demonstration, only. Of course, you are more than -welcome to clone from this repository and fork your own. - - [$XDG_CONFIG_HOME/vcsh/repo.d/zsh.git] - checkout = vcsh clone 'git://github.com/RichiH/zshrc.git' zsh - update = vcsh zsh pull - push = vcsh zsh push - status = vcsh zsh status - gc = vcsh zsh 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 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 - -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] - 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, [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 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.
