deezconfigs

Manage deez config files.

deezconfigs will mirror your config files to your $HOME directory (sync) and synchronize them back (rsync). Additionally, you can choose to symlink the files instead (link).

Same idea as GNU Stow or chezmoi, but simpler, requiring less neuron activation to operate.

What does deezconfigs do?

The core of deezconfigs is to replicate the file structure of a given directory (i.e., the config root), inside the Home. The main purpose of this is to keep all the config files in one place, making it easy to version them.

deezconfigs is very un-opinionated by default. It tries to do its job well (syncing config files), while avoiding to do what other tools do better. For instance, there is no automatic versioning, no embedded text editor, and no templating. You absolutely can do all of the above, but it's not something that's forced on you. It's your processes, your tools. All the extensibility power lies in hooks (read further below).

Copying vs. Linking

deezconfigs supports two configuration models: copying and linking. Both models come with different trade-offs. For instance, linking ensures files are always up-to-date, but on the flip-side, you can't really have machine specific configuration. On the other hand, copying files need to be kept up-to-date manually by syncing or rsyncing all changes. But, having separate copies makes it easier to keep configuration generic in the root, and specific in the Home.

The Config Root

As mentioned before, the config root is any directory whose structure you want to replicate in the Home directory.

That said, you should, but are not required to, create a .deez file in the root. This lets deezconfigs know it is safe to use. If deezconfigs doesn't find a .deez file, it will ask you confirmation before modifying you file system. This is a security feature to prevent you from accidentally messing up your Home if you run deez from the wrong directory.

Another advantage of creating a proper root is that that it lets you run deez inside sub-directories as well. Just like you can run Git commands from anywhere in the repo, deezconfigs is smart enough to search for a root in parent directories before warning you that the current directory is not a root.

Home

This is the directory where config files are copied or symlinked to. On Unix, this is read from the HOME environment variable, and on Windows from USERPROFILE.

Using a different Home is not natively supported by an argumment, but you can override the environment variable to achieve what you want.

$ HOME=/home/other deez sync

Sync

Syncing in deezconfigs replicates the file structure from the config root inside the Home directory (minus ignored files).

# Sync current config root.
$ deez sync

# Sync given config root, verbosely.
$ deez --verbose sync ~/configs

# Sync from remote.
$ deez sync git:https://github.com/qrichert/configs

rSync

Reverse-syncing is the complimentary opposite of syncing: it updates your config files in the root with the current content from Home.

# 1. Sync your config file to your Home.
$ deez sync

# 2. Make some changes.
$ vim ~/.gitconfig

# 3. rSync the changes back into your root.
$ deez rsync

Link

Linking is the same as syncing, but it creates symbolic links in the Home instead of copying files. Linking has no rsync equivalent because linked files are always up-to-date.

# Symlink current config root.
$ deez link

Status

Status prints the list of configuration files with their respective state of 'syncness', and also prints your hooks.

Configuration files can be:

S  In Sync
M  Modified
!  Missing

Diff

Diffing prints the line-diff between your config root and your Home. This shows you exactly what has changed and where. There is not merge feature however, as merging is best done by your VCS.

Clean

Cleaning is removing all the files and symlinks from the Home.

# 1. Link your files to your Home.
$ deez link

# 2. Now remove all the links you've just created.
$ deez clean

Ignore some files

By default, deezconfigs ignores all the hook files (at the root) the .git directory at the root (if any), all .ignore and .gitignore files, and all .deez files, wherever they are (enabling multi-root repos).

You can extend this list by adding entries to your .ignore and/or .gitignore files, they are both respected by deezconfigs.

If you want to both version a file in Git and have it ignored by deezconfigs, you can either add it to a .gitignore and git add -f it, or you can use a generic .ignore file instead.

Hooks

deezconfigs let you run hooks before and after commands. Hooks are scripts or executables located at the root and whose names match the following pattern:

(pre|post)-<command>[.extension]

A common example would be...

post-sync.sh

...a shell script that gets run after every deez sync command.

You can have multiple hooks for the same action; they will be run in name order (post-sync.001.sh, then post-sync.002.sh, etc.).

Hooks are executed through sh. It is roughly equivalent to:

$ cd <root>
$ export DEEZ_...  # deez envionrment variables.
$ sh -c "<root>/<hook>"

Note that you'll likely want the scripts to start with a shebang (e.g., #!/usr/bin/env python3).

As an example, here are two complimentary scripts that respectively set and unset Git's email address in the .gitconfig file when you sync and rsync it:

$ cat post-sync.sh
#!/usr/bin/env bash
[[ -n $DEEZ_VERBOSE ]] && echo "Set global Git email address."
git config --global user.email your.email@example.com

$ cat post-rsync.sh
#!/usr/bin/env bash
[[ -n $DEEZ_VERBOSE ]] && echo "Unset Git email address."
git config --file ./.gitconfig user.email '<>'

They both make use of the DEEZ_VERBOSE environment variable to enrich the output of deez in verbose mode.

deezconfigs passes a few envionrment variables to hooks to make your life easier:

• DEEZ_ROOT Absolute path to the config Root. This is equal to pwd on Unix systems, since hooks are run in the root.
• DEEZ_HOME Absolute path to the Home directory. This is equal to $HOME on Unix systems.
• DEEZ_VERBOSE Will be true if run in verbose mode, otherwise it will be unset (hint: use [[ -n $DEEZ_VERBOSE ]] to test for existance).
• DEEZ_OS Contains the name of the current operating system (e.g, linux, macos, windows, etc.). The name is a re-export of Rust's std::consts::OS.

Templating

There is no built-in templating in deezconfigs, but you can implement simple to very tailored templating with hooks. From simple sed commands, to something way more advanced like Jinja2 in Python.

Copy some files, and link others

Use mutliple roots. You can have multiple roots (subdirectories) in one repo. Use sync in one, and link in the other.

If you need anything more advanced than that, deezconfigs is likely not the right tool for you.

Roadmap

• Command sync.
• Command rsync.
• Command link.
• Command status.
• Command diff.
• Command clean.
• Think about allowing ignore files everywhere (i.e., never sync ignore files).
• Refactor tests, there is too much duplication (everything ignore and walk can be tested once for all commands).
• Refactor argument parsing? Maybe?
• Add hooks examples.
• Increase test coverage (features are mostly covered, what's missing are tests for the error cases).
• Perf refactorings for bottlenecks (or for fun).
