dotfiles

• Originally forked from Mathias Bynens's great dotfiles repo, now detached.
• OSX only, setup for >M1 Macs (where homebrew install location changed).
• Primary shell is fish.
• Use chezmoi for management.

Setup

1. Install homebrew
2. Install chezmoi (brew install chezmoi works)
3. (optional) Create a ~/.config/chezmoi/chezmoi.toml file:

# Your chezmoi settings

[data]
    # Set these to start with a default Git identity
    git_email = "<your git email>"
    git_name = "<your git name>"
    git_signingkey = "<the git ssh signing key id>"

    hostname = "<hostname>"  # Remove to leave hostname alone

    run_osx_setup = "false"  # Set to `false` to automatically run the osx setup script, defaults enabled

    # Set to `true` or remove to enable application installation through mas, defaults enabled
    brew_skip_mas = "<true | false>"
    brew_skip_casks = "<true | false>"

    onepassword_agent_keys = [
      {vault = "<vault name>", item = "<key name>"},
      ...
    ]

3. Run chezmoi init lirsacc and chezmoi apply

Notes

Split homebrew bundle files

I couldn't find a way to easily disable all mas or all casks. The $HOMEBREW_BUNDLE_*_SKIP variables seem to want a list of specific entries and setting the to 1 doesn't do anything. There are also a --mas or --casks option but --no-mas / --no-casks aren't a thing.

The workaround is to split the brewfiles and not use a global one. This makes it a bit more cumbersome to do things like brew bundle cleanup or simply install all the things but brew bundle --file - does work with stdin so this works:

cat ~/.config/homebrew/Brewfile* | brew bundle --file -

This is abstracted out under the fish function brew-bundle-all.

This works for my setup where I don't constantly add / remove things from the Brew bundle.

Mise vs homebrew

It's a bit fuzzy where I use mise vs. brew to install something, and sometimes there's both but generally mise is used when it's likely I'll need different versions across different projects.

On individual machines I can create a ~/.mise.toml to record machine specific tools & overrides to be used.

Git config

• A default identity can be configured through the chezmoi data.
• This uses 1Password for loading SSH keys by default.
• You can also create a ~/.config/git/overrides.gitconfig file locally which won't be managed and is loaded last.

Git config & identity per directory

A pattern I use often is to have a git identity per directory (e.g. one per GitHub organisation, GitHub instance, etc.). You can achieve this by adding blocks like this in the gitconfig:

[includeIf "gitdir:~/projects/my-organisation/"]
  path = ~/projects/my-organisation/.gitconfig

I haven't found a way to automatically detect those, although something could probably be hacked around through the same prompt-hacks tools mise use to detect the closest config file.
