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.

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.
