1 vcsh - manage and sync config files via git
12 vcsh allows you to have several git repositories, all maintaining their working
13 trees in $HOME without clobbering each other. That, in turn, means you can have
14 one repository per config set (zsh, vim, ssh, etc), picking and choosing which
15 configs you want to use on which machine.
17 vcsh was designed with [mr] [1] in mind so you might want to install that, as
20 Read INSTALL.md for detailed setup instructions.
22 The following overview will try to give you an idea of the use cases and
23 advantages of vcsh. See sections 3 and 4 for detailed instructions and
28 ## 2.1 Comparison to Other Solutions ##
30 Most people who decide to put their dotfiles under version control start with a
31 **single repository in $HOME**, adding all their dotfiles (and possibly more)
32 to it. This works, of course, but can become a nuisance as soon as you try to
33 manage more than one host.
35 The next logical step is to create single-purpose repositories in, for example,
36 ~/.dotfiles and to create **symbolic links in $HOME**. This gives you the
37 flexibility to check out only certain repositories on different hosts. The
38 downsides of this approach are the necessary manual steps of cloning and
39 symlinking the individual repositories. It will probably become a nuisance when
40 you try to manage more than two hosts.
42 **vcsh** takes this second approach one step further. It expects
43 **single-purpose repositories** and stores them in a hidden directory (similar
44 to ~/.dotfiles). However, it does not create symbolic links in $HOME; it puts
45 the **actual files right into $HOME**.
47 Furthermore, by making use of [mr] [1], it makes it very easy to enable/disable
48 and clone a large number of repositories. The use of mr is technically optional
49 (see 4.3), but it will be an integral part of the proposed system that follows.
51 ## 2.2 Default Directory Layout ##
53 To illustrate, this is what a possible directory structure looks like.
60 | | | |-- gitconfigs.vcsh
62 | | | |-- offlineimap.vcsh
66 | | | |-- vimperator.vcsh
67 | | | `-- snippets.git
69 | | |-- zsh.vcsh -> ../available.d/zsh.vcsh
70 | | |-- gitconfigs.vcsh -> ../available.d/gitconfigs.vcsh
71 | | |-- tmux.vcsh -> ../available.d/tmux.vcsh
72 | | `-- vim.vcsh -> ../available.d/vim.vcsh
75 | |-- zsh.git -----------+
76 | |-- gitconfigs.git |
80 |-- .zshrc <----------------------+
87 The files you see in ~/.config/mr/available.d are mr configuration files that
88 contain the commands to manage (checkout, update etc.) a single repository.
89 vcsh repo configs end in .vcsh, git configs end in .git, etc. This is optional
90 and your preference. For example, this is what a zsh.mrconfig with read-only
91 access to my zshrc repo looks likes. I.e. in this specific example, push can
94 [$HOME/.config/vcsh/repo.d/zsh.git]
95 checkout = vcsh clone 'git://github.com/RichiH/zshrc.git' zsh
96 update = vcsh run zsh git pull
97 push = vcsh run zsh git push
98 status = vcsh run zsh git status
99 gc = vcsh run zsh git gc
103 ~/.config/mr/available.d contains *all available* repositories. Only
104 files/links present in mr/config.d, however, will be used by mr. That means
105 that in this example, only the zsh, gitconfigs, tmux and vim repositories will
106 be checked out. A simple `mr update` run in $HOME will clone or update those
107 four repositories listed in config.d.
111 Finally, ~/.mrconfig will tie together all those single files which will allow
112 you to conveniently run `mr up` etc. to manage all repositories. It looks like
117 include = cat ~/.config/mr/config.d/*
121 ~/.config/vcsh/repo.d is the directory into which vcsh clones the git
122 repositories. Since their working trees are configured to be in $HOME, the
123 files contained in those repositories will be put in $HOME directly (see .zshrc
127 vcsh will check if any file it would want to create exists. If it exists, vcsh
128 will throw a warning and exit. Move away your old config and try again.
129 Optionally, merge your local and your global configs afterwards and push with
130 `vcsh run foo git push`.
132 ## 2.3 Moving into a New Host ##
134 To illustrate further, the following steps could move your desired
135 configuration to a new host.
137 1. Clone the mr repository (containing available.d, config.d etc.); for
138 example: `vcsh clone git://github.com/RichiH/vcsh_mr_template.git`
139 2. Choose your repositories by linking them in config.d (or go with the default
140 you may have already configured by adding symlinks to git).
141 3. Run mr to clone the repositories: `cd; mr update`.
144 Hopefully the above could help explain how this approach saves time by
146 1. making it easy to manage, clone and update a large number of repositories
148 2. making it unnecessary to create symbolic links in $HOME (thanks to vcsh).
150 If you want to give vcsh a try, follow the instructions below.
152 # 3 Getting Started #
154 Below, you will find a few different methods for setting up vcsh:
157 2. The Steal-from-Template Way
160 ### 3.1 The Template Way ###
162 #### 3.1.1 Prerequisites ####
164 Make sure none of the following files and directories exist for your test
165 (user). If they do, move them away for now:
169 * ~/.config/mr/available.d/mr.vcsh
170 * ~/.config/mr/available.d/zsh.vcsh
171 * ~/.config/mr/config.d/mr.vcsh
172 * ~/.config/vcsh/repo.d/mr.git/
174 All of the files are part of the template repository, the directory is where
175 the template will be stored.
179 #### 3.1.2 Clone the Template ####
183 git clone git://github.com/RichiH/vcsh.git vcsh
185 ln -s vcsh /usr/local/bin # or add it to your PATH
187 vcsh clone git://github.com/RichiH/vcsh_mr_template.git mr.vcsh
189 #### 3.1.3 Enable Your Test Repository ####
192 mv ~/.zshrc ~/zshrc.bak
193 cd ~/.config/mr/config.d/
194 ln -s ../available.d/zsh.vcsh . # link, and thereby enable, the zsh repository
198 #### 3.1.4 Set Up Your Own Repositories ####
200 Now, it's time to edit the template config and fill it with your own remotes:
202 vim .config/mr/available.d/mr.vcsh
203 vim .config/mr/available.d/zsh.vcsh
205 And then create your own stuff:
208 vcsh run foo git add -f bar baz quux
209 vcsh run foo git remote add origin git://quuux
210 vcsh run foo git commit
211 vcsh run foo git push
213 cp .config/mr/available.d/mr.vcsh .config/mr/available.d/foo.vcsh
214 vim .config/mr/available.d/foo.vcsh # add your own repo
218 ### 3.2 The Steal-from-Template Way ###
220 You're welcome to clone the example repository:
222 git clone git://github.com/RichiH/vcsh_mr_template.git
224 Look around in the clone. It should be reasonably simple to understand. If not,
225 poke me, RichiH, on Freenode (query) or OFTC (#vcs-home).
228 ### 3.3 The Manual Way ###
230 This is how my old setup procedure looked like. Adapt it to your own style or
231 copy mine verbatim, either is fine.
237 # Clone vcsh and make it available
238 git clone git://github.com/RichiH/vcsh.git vcsh
239 sudo ln -s ~/work/git/vcsh/vcsh /usr/bin/local
242 Grab my mr config. see below for details on how I set this up
244 vcsh clone ssh://<remote>/mr.git
245 cd ~/.config/mr/config.d/
246 ln -s ../available.d/* .
249 mr is used to actually retrieve configs, etc
253 include = cat ~/.config/mr/config.d/*
254 ~ % echo $XDG_CONFIG_HOME
256 ~ % ls $XDG_CONFIG_HOME/mr/available.d # random selection of my repos
257 git-annex gitk.vcsh git.vcsh ikiwiki mr.vcsh reportbug.vcsh snippets.git wget.vcsh zsh.vcsh
259 # then simply ln -s whatever you want on your local machine from
260 # $XDG_CONFIG_HOME/mr/available.d to $XDG_CONFIG_HOME/mr/config.d
266 ### 4.1 Keeping repositories Up-to-Date ###
268 This is the beauty of it all. Once you are set up, just run:
275 ### 4.1 Making Changes ###
277 After you have made some changes, for which you would normally use `git add`
278 and `git commit`, use the vcsh wrapper (like above):
280 vcsh run foo git add -f bar baz quux
281 vcsh run foo git commit
282 vcsh run foo git push
284 By the way, you'll have to use -f/--force flag with git-add because all files
285 will be ignored by default. This is to show you only useful output when running
286 git-status. A fix for this problem is being worked on.
288 ### 4.3 Using vcsh without mr ###
290 vcsh encourages you to use [mr] [1]. It helps you manage a large number of
291 repositories by running the necessary vcsh commands for you. You may choose not
292 to use mr, in which case you will have to run those commands manually or by
295 #### A Few Examples ####
297 To initialize a new repository: `vcsh init zsh`
299 To clone a repository: `vcsh clone ssh://<remote>/zsh.git`
301 To interact with a repository, use the regular Git commands, but prepend them
302 with `vcsh run $repository_name`. For example:
304 vcsh run zsh git status
305 vcsh run zsh git add -f .zshrc
306 vcsh run zsh git commit
308 Obviously, without mr keeping repositories up-to-date, it will have to be done
309 manually. Alternatively, you could try something like this:
311 for repo in `vcsh list`; do
312 vcsh run $repo git pull;
