I just use a git repo and GNU Stow similar to the approach in this post (I'm not the author of the post):

https://tamerlan.dev/how-i-manage-my-dotfiles-using-gnu-stow...

Stow is usually trivially installable using the package manager while I'm installing git. Not nearly as full featured as chezmoi but gets the job done for me.

I've seen projects like this for years and I still have the genuinely honest question: what are people doing that managing their dotfiles is significant problem for them?

I've managed my dotfiles (12 different configuration files all compatible with cygwin, wsl, linux, macOS) for the past decade in a git repo with a 50 LOC shell script that creates symlinks for me in an intelligent way. What am I missing?

You're missing Windows, GUI apps, and the other dozens of cli apps above 12? Also cases where symlinks break because apps delete configs before saving and the ability to differentiate between systems easier. Also the final output config is cleaner/more readable if cross-OS compatibility is offloaded to a config manager. Then templates/vars can make configs cleaner /easier to update (e.g. moved some portable apps from C to D to save ssd space, can update one var). Also can limit config diff noise by ignoring unimportant changes like latest app window position

If that works for you, great. I split files up into multiple repos and manage them with VCSH. The modular approach lets me configure multiple machines differently. I have config on my work laptop that shouldn’t end up on my personal devices, vice versa. I don’t really need my i3 config on my MacBook Pro. Ditto for XDG paths, just as I have macOS config that doesn’t have a natural fit on a Linux desktop.

I could use one repo for work and one for personal and live with the mess of useless files, but I like the cleanliness and having simple git histories. I also don’t have to have conditional statements all over the place.

I use chezmoi, and I didn’t have to write a 50-line script - just install chezmoi on a new machine, run a command pointing it to a git repo, and up pop all the dot files and configs I need to have a consistent environment everywhere.

Chezmoi also handles variations in config files for personal vs. Work machines, or even differences between machines themselves.

I agree it’s not a tremendous lift to write a bespoke solution for this (and I did so in the past) but at some point it becomes lower-effort to use something off the shelf.

In addition to that, chezmoi templating can be used to fill in environment variables like secret keys, you just need to unlock rbw or whatever other password manager it is that you use. I have some that I export in my shell config, and this setup allows me to have the repo in a public place and not worry about who finds it.

I use home-manager for my dotfiles, and they manage quite a few things.

For example:

1. My editor config (neovim) including downloading and installing all my plugins, including the dependencies of the plugins (including deno, rust-analyzer, clippy, etc)

2. All the other tools I use, like ripgrep, python, and so on, including installing the same version on every machine I've got.

3. A bunch of misc programs and scripts I've written for myself, including all their dependencies

4. All the xdg configuration to open http links in the right browser profile, pdfs in evince, etc, as well as all the programs needed for that

5. systemd user units to run various daemons, like syncthing to sync some documents between computers, gpg-agent, etc etc.

And this works on all machines running any linux distro, from arch linux to nixos to ubuntu.

home-manager is just another dotfile manager, but since nix makes packages isolated, such that my user version of $pkg doesn't conflict or depend on the host version, home-manaer can also safely manage applications I run, like my editor, browser, developer tools, systemd units, etc etc etc.

I agree that most dotfile managers are weird overengineered projects that could have been a short shell script.

I think nix+home-manager is a weird overengineered project that could not have been a shell script.

Why is "written in Rust" as important as what the software is about? I noticed this tendency of specifying when something is written in Rust.

Should it be an indicator of better stability? Or performance? And if so, am I interested in the performance of a dotfile tool?

Genuinely curious.

It means I can install it easily and it's probably going to work well on the first try, and it'll likely start up and run fast.

It also uses clap for argument parsing so I know I can run it with `--help` to discover its options, and that the parsing of flags is likely not buggy, and consistent with other Rust tools I use.

None of this is _guaranteed_ with Rust, but the tooling and libraries make it so much easier for you to succeed at making a fast and robust piece of software. So for me "written in Rust" is usually a quality indicator of sorts. It's not 100% though, there will always be misses because it's still very possible to write bad software in any language.

Easy to deploy, usually single static binaries. Same goes with Golang projects. Polar opposite of java (which I'll totally ignore).
serbuvlad 3 hours ago [-]
Very funny to me that Java's initial appeal: it's easy to deploy "everywhere"; is now it's disadvantage (you need a whole Java setup with JAVA_HOME and God knows what else).

Now the bar for GUI apps is cross-compilation to deployable web, Windows, Linux (Electron), Android, iOS (? I don't know I don't use/develop for Apple products) versions from running a simple command.

And for the CLI world, well, almost everyone is on Linux x86-64, or maybe arm, so a few static binaries (or "virtually" static -- depending only on glibc) are king for deployment.

I don’t find installing a JVM a massive amount of work (no more so than any other interpreted language), but nowadays you can AOT compile Java to a native binary if that’s your hang-up:

There’s a new LTS release with improvements coming out next week.

I've never really had any of the issues that is mentioned in the bullet points. I use the Atlassian post on storing dotfiles [1] for several years now.

* It's easy to setup on a new machine, no creating symlinks on every setup

* I create separate branches for different machines/environments. Like, currently, I have a branch for macos and my master branch is for devcontainer, but I have had a linux branch too.

I copied the post to a markdown as a README in the repository in the off chance Atlassian deletes the post for some reason.

Most recently, I started moving any config files I could into the .config to keep the home directory clean. i.e. .config/git .config/fish and .config/zsh

git bare repo handles dotfiles better than any bespoke platform

1. git is already there and familiar

2. sync dotfiles over ssh . no internet access or separate credentials needed (for github, s3 etc)

3. handles merge conflicts

4. easily push & pull subdirectories into /etc , /usr/local or wherever else you need configuration using git subtree.

git bare repo works for tracking files anywhere on the FS as well. (check debian etckeeper for automating that)

Now that 20225 has become “The Year of the Terminal”(R), I have been looking at how managing my dot files in a more coherent way. I was thinking straight up git vs stow, but I should would be very interested in comparisons from those who have used this tool.

Chezmoi is what you want.

I haven't looked at this one yet, but until someone compares it to Chezmoi and points out where it's better I'm not even looking attention I fear. Chezmoi is just that good.

announcer4614 4 hours ago [-]
For the sake of answering the parent question with regard to Chezmoi specifically: Chezmoi is a very comprehensive dotfiles manager. It can do a lot of things. More than any other I'm aware of.

More does not necessarily equal better, though. I think that's a matter of personal preference. I tried Chezmoi for a while and ultimately decided it was just a lot more levers at my disposal than I really wanted to even think about.

Dotter, by contrast, is a lot more minimal. Dotter is little more than a symlink manager plus templating engine plus config files to declare what machines need what config.

Chezmoi is all that, and does a lot more: encryption/decryption (even has password manager integrations), automatic push/pull. It's also designed so that you can add or manage files regardless of what your current working directory is (via commands like `chezmoi edit/add`).

In my case, after deciding I wanted to go for the minimal end of things, I almost went for GNU Stow however, I wanted templating functionality and I liked dotter's "packages" system for defining what files a given computer needs.

And very much a personal bias here: I found the learning curve of Chezmoi templates not great. I'm also not a big fan of the fact that Chezmoi relies on you naming your source files in particular ways in order to determine what the target file permissions should be.

Wait until you get a load of nix's home manager!

How do you manage system wide settings? I've been using ansible, but it seems a bit overkill. I feel it's over complicating things.

I use my dotfiles repo for this.

For example in my dotfiles repo I'll have `etc/pacman.d/01-options.conf` and the dotfiles install script will symlink that to `/etc/pacman.d/01-options.conf`. This way the source of truth is always in a single dotfiles repo.

This strategy has worked well for dotfiles I use on Arch, Debian, Ubuntu and macOS. It includes support for WSL 2 too. The install script has been working with this set up for years to run 1 single command and have everything work where work in this case is installing and configuring a bunch of tools I use. An example is here https://github.com/nickjj/dotfiles.

Not GP.

I tarball /etc. On a new system, I restore config quite carefully.

I made a post recently on HN about this. All you need is git. It does everything. I didn't know why people want symlinks and everything else.

I've been using "homegit" for years and never felt the need for a replacement.

great tip! also for /etc

I found it quite useful. My main use case for it is managing the same dotfiles for Windows and Linux. Specifically that neovim uses different folders and I can set that per OS in dotter.

It also allows for including our not including a config based on an executable being available which can be useful. It requires some configuration, depending on how many of its features you use but I think it's worth it.

Thanks. I’m between Omarchy and MacOS mostly, but sometimes Windows, too. Seems worth putting some time into it.

If all you want is GNU Stow with a bit nicer UX, I wrote and have been using https://github.com/bbkane/fling for a few years now. See the demo gif in the README for the UX

I've been using dotter for 5+ years and it's been an amazing tool. Doesn't go all in like NixOS, but lets you get close to that functionality by allowing templating to reuse a single dotfile repo across different systems. I also like how you can easily conditionally select configurations and scripts to load depending on environment.

I have a backup/restore set of scripts that copies my dot files over as well as a few directories as a whole via rsync.

My only big issue is how big ~/.config/ gets as a directory compared to how much I really want to keep/need in terms of a fresh setup. Similar for my ~/src/ directory, with all the ./.git/ files. I kind of wish there were a "smarter" backup/restore tool that could handle a few of these things better than ham-fisting and rsyncing all the things.. I was more selective in my restore when configuring my new computer earlier in the year.

Try Stow. You can create packages for your stuff and symlink the files as needed. I have packages like git, shell, mail,…

I wish it had more examples or some basic documentation website, it looks interesting cuz i have a lot of context switching through all my tools.
