Manage Your Configs with vcsh
Now that you've got your mr repo cloned, you'll want to go in and edit the files to point to your setup. The control files for mr live in ~/.config/mr/available.d, so go to that directory:
bill@test2:~/.config/mr/available.d$ ls mr.vcsh zsh.vcsh
Rename the zsh.vcsh file to vim.vcsh, because you're working with vim, and change the repository path to point to your server:
bill@test2:~/.config/mr/available.d$ mv zsh.vcsh vim.vcsh bill@test2:~/.config/mr/available.d$ vi vim.vcsh [$HOME/.config/vcsh/repo.d/vim.git] checkout = vcsh clone git@gitserver:vim.git vim
Also, edit the mr.vcsh file to point to your server as well:
bill@test2:~/.config/mr/available.d$ vi mr.vcsh [$HOME/.config/vcsh/repo.d/mr.git] checkout = vcsh clone git@gitserver:mr.git mr
The mr tool relies on symlinks from the available.d directory to the config.d directory (much like Ubuntu's Apache configuration, if you're familiar with that). This is how mr determines which repositories to sync. Since you've created a vim repo, make a symlink to tell mr to sync the vim repo:
bill@test2:~/.config/mr/available.d$ cd ../config.d bill@test2:~/.config/mr/config.d$ ls -l total 0 lrwxrwxrwx 1 bill bill 22 Jun 11 18:14 mr.vcsh -> ↪../available.d/mr.vcsh bill@test2:~/.config/mr/config.d$ ln -s ↪../available.d/vim.vcsh vim.vcsh bill@test2:~/.config/mr/config.d$ ls -l total 0 lrwxrwxrwx 1 bill bill 22 Jun 11 18:14 mr.vcsh -> ↪../available.d/mr.vcsh lrwxrwxrwx 1 bill bill 23 Jun 11 20:51 vim.vcsh -> ↪../available.d/vim.vcsh
Now, set up mr to be able to sync to your git server:
bill@test2:~/.config/mr/config.d$ cd ../.. bill@test2:~/.config$ vcsh enter mr bill@test2:~/.config$ ls mr vcsh bill@test2:~/.config$ git add mr bill@test2:\~/.config$ git commit -m 'Initial Commit' [master fa4eb18] Initial Commit Committer: Bill Childers [firstname.lastname@example.org] 3 files changed, 4 insertions(+), 1 deletion(-) create mode 100644 .config/mr/available.d/vim.vcsh create mode 120000 .config/mr/config.d/vim.vcsh bill@test2:\~/.config$ git remote add origin git@gitserver:mr.git fatal: remote origin already exists.
Oh no! Why does the remote origin exist already? It's because you cloned the repo from the author's repository. Remove it, then create your own:
bill@test2:~/.config$ git remote show origin bill@test2:~/.config$ git remote rm origin bill@test2:~/.config$ git remote add origin git@gitserver:mr.git bill@test2:~/.config$ git push -u origin master Counting objects: 28, done. Compressing objects: 100% (21/21), done. Writing objects: 100% (28/28), 2.16 KiB, done. Total 28 (delta 2), reused 0 (delta 0) To git@gitserver:mr.git * [new branch] master -> master Branch master set up to track remote branch master from origin. bill@test2:~/.config$ exit
That's it! However, now that mr is in the mix, all you need to do to set up a
new machine is do a
vcsh clone git@gitserver:mr.git mr to clone your mr
repository, then do an
mr up, and that machine will have all your repos
vcsh is a very powerful shell tool, and one that takes some time to adapt your thought processes to. However, once you do it, it makes setting up a new machine (or account on a machine) a snap, and it also gives you a way to keep things in sync easily. It's saved me a lot of time in the past few months, and it's allowed me to recover quickly from a bad configuration change I've made. Check it out for yourself!
Setting up a Remote Git Repo
A quick note on setting up a remote git repo: you'll need to set up passwordless authentication using SSH keys (see Resources for more information). Once you have that going using a "git" user, you simply need to create a git repo as the git user. That's done easily enough, just run the command:
git@gitserver:~$ git init --bare vim.git Initialized empty Git repository in /home/git/vim.git/
Your bare repo will be ready for your vcsh client to check in stuff!
