Target file

home/.chezmoiscripts/packages/run_before_darwin_homebrew.sh.tmpl

Process

1. •Get package name from arguments: $ARGUMENTS
2. •Check if package exists: brew info $ARGUMENTS
3. •Determine package type:
   • •Formula (brew): brew info --json=v2 $ARGUMENTS | jq '.formulae'
   • •Cask: brew info --json=v2 --cask $ARGUMENTS | jq '.casks'
4. •Read the Homebrew script
5. •Find the appropriate list:
   • •$brews for formulae
   • •$casks for casks
6. •Check if already present
7. •Add in alphabetical order within the list
8. •If package is tool-specific (e.g., Go tool), add in conditional block:
   go

   {{- if .with_golang -}}
   {{-   $brews = concat $brews (list "new-go-tool") -}}
   {{- end -}}
   

Output

• •If already present: inform user
• •If added: show the edit made
• •If package not found: error with suggestion

Example usage

/brew-add htop        # Adds to $brews
/brew-add slack       # Adds to $casks
/brew-add golangci-lint  # Adds to conditional Go block

Notes

• •Maintain alphabetical order in lists
• •Use existing conditional patterns for tool-specific packages
• •Run chezmoi diff after to verify change
