Usage

I just cloned my repository, but yadm status shows conflicts. Why?

Prior to cloning your repository, files managed by yadm already existed. For example, imagine you are logged into a system and $HOME/.bash_profile already exists. If you then clone your yadm repository—which also contains .bash_profile—then you will likely get a conflict. You must decide how to resolve that conflict. Perhaps you don't want to overwrite the current version. You might want merge the content together in some way. This can be resolved the same way you resolve any Git conflict.

If you merely want to forcefully overwrite all the managed files using the HEAD revision of your repository, you probably want to run

yadm reset --hard HEAD

While committing I got the message, "Please tell me who you are". Why?

Whenever a Git commit is generated, Git requires information about the author of the commit. This can be configured via the git config command. Usually the best approach is to configure this information globally, and then manage your global Git configuration via yadm. This allows the configuration to follow you wherever your dotfiles live.

git config --global "user.email" "your-email@domain"
git config --global "user.name"  "Your Name"

yadm add ~/.gitconfig

However, if you want commits to your yadm repo to use a different author, you can configure these settings in the yadm repo itself.

yadm gitconfig "user.email" "alternate-email@domain"
yadm gitconfig "user.name"  "Alternate Name"

Note: Configuring these settings directly in the yadm repo will require you to configure it each time you clone the repo.

How can I display untracked files with a yadm status command?

By default, yadm is configured to ignore untracked files when displaying a status. You can use the -u paramter on the status command to alter how untracked files are treated. -unormal will show untracked files and directories.

yadm status -unormal

If you want to change the default treatment, you can change this configuration on the yadm repository itself.

yadm gitconfig --unset status.showUntrackedFiles

How can I stage all modified files at once?

Just as with Git, you can use the add command.

yadm add -u :/

(Starting with Git 2.0, the :/ is not necessary)

How can I change the URL of my remote yadm repository?

This is done the same way you change the URL of any Git repository.

yadm remote set-url origin <NEW-URL>

This could be useful if you manage your ssh keys in the yadm repository. That could make it difficult to initially clone the repository using the ssh protocol. You can start by cloning the repository using the https protocol (and providing a password), and then change the repository's URL after you've decrypted your ssh keys.

I've customized yadm configurations (stored in ~/.yadm/config). Should I add that to my repository?

Certainly. That is a good way to carry your yadm configurations around (just like the rest of your dotfiles).

Can you point to any example yadm managed repositories?

This page contains some examples.

Encryption

Can I use yadm without gpg?

Of course. You only need gpg installed if you plan on using the encrypt/decrypt features. yadm will tell you if it is missing a dependency for any command.

Should I yadm add my .yadm/encrypt file?

Yes! This way your configuration for what files should be encrypted will follow you when you clone your repository.

Should I yadm add encrypted files to repository?

No, you should not. Files you want encrypted should be added to the file .yadm/files.gpg using the yadm encrypt command. Then .yadm/files.gpg should be added to the yadm repository. This way, only an encrypted collection of those files are put into the repository. After cloning or updating your repository, you can use yadm decrypt to extract those files from .yadm/files.gpg. See the encryption help for more details.

I modified an encrypted file, but yadm doesn't show any modifications. Why?

If you changed files which are matched by .yadm/encrypt, you must re-run yadm encrypt to generate a new version of .yadm/files.gpg. Then .yadm/files.gpg can be added to a new commit.

Can I use yadm and git-crypt?

There is an experimental version of yadm which can use git-crypt. You can find it in the git-crypt-support branch. See the notes in the commit messages of that branch for details.

Comparisons

How does yadm differ from homeshick?

yadm and homeshick are both written in Bash, with very limited dependencies. However, homeshick works by symlinking data from a repository working directory into your $HOME directory. yadm instead uses your $HOME directory as its working directory. homeshick allows for multiple "castles" to be linked into $HOME, while yadm is designed to work with a single repository. homeshick requires you to change into the "castle" directory before performing any Git based commands. yadm allows you to perform operations regardless of your location. yadm also includes unique features to encrypt private data, and symlink alternate versions of files based on OS type or hostname.

How does yadm differ from vcsh?

yadm and vcsh both work as a filters for standard Git commands. Both also use your $HOME directory as the repository's working directory. However, vcsh is designed to work with multiple repositories, yadm instead uses a single repository. vcsh requires you to specify which repository you want to operate on, while yadm only operates on one. If you want to use Git submodules, you may have trouble using vcsh. This is because only one repository can be the owner of the .gitmodules file. yadm also includes unique features to encrypt private data, and symlink alternate versions of files based on OS type or hostname.
