macOS

Use brew bundle to manage your brews and casks

Homebrew's brew bundle subcommand allows you to specify a list of brews and casks to be installed. You can integrate this with chezmoi by creating a run_onchange_ script. For example, create a file in your source directory called run_onchange_before_install-packages-darwin.sh.tmpl containing:

{{- if eq .chezmoi.os "darwin" -}}
#!/bin/bash

brew bundle --file=/dev/stdin <<EOF
brew "git"
cask "google-chrome"
EOF
{{ end -}}

!!! note

The `Brewfile` is embedded directly in the script with a bash here
document. chezmoi will run this script whenever its contents change, i.e.
when you add or remove brews or casks.

Determine the hostname

The result of the hostname command on macOS depends on the network that the machine is connected to. For a stable result, use the scutil command:

{{ $computerName := output "scutil" "--get" "ComputerName" | trim }}

Run script after every macOS update

You can automate a script to run after each macOS update by creating a run_onchange_ script and using the output template function to run sw_vers:

# MacOS build version: {{ output "sw_vers" "--buildVersion" }}
