Machine Profiles

This dotfiles setup supports two machine profiles: work and personal. The profile determines which packages are installed, which configurations are applied, and which environment variables are set.

Profile Detection

Automatic Detection

The profile is auto-detected from your machine's hostname during chezmoi init:

// In .chezmoi.toml.tmpl
{{- $machineType := "personal" -}}
{{- if or (contains "work" .chezmoi.hostname) (contains "corp" .chezmoi.hostname) (contains "talview" .chezmoi.hostname) -}}
{{-   $machineType = "work" -}}
{{- end -}}

Hostnames that trigger "work" profile:

  • Contains work (e.g., macbook-work)
  • Contains corp (e.g., corp-laptop)
  • Contains talview (e.g., talview-dev)

Manual Override

During first run, you're prompted to confirm or change:

Machine type (work/personal) [personal]:

To change later, edit ~/.config/chezmoi/chezmoi.toml:

[data.machine]
    type = "work"  # Change to "personal" or "work"

Then re-apply:

chezmoi apply

Profile Differences

Work Profile

When .machine.type == "work":

Category Behavior
npm packages Installs @openai/codex CLI
Environment Sets CODEX_BASE_URL for LiteLLM proxy
Paths Adds work-specific tool paths
Aliases Work-related shortcuts

Personal Profile

When .machine.type == "personal":

Category Behavior
npm packages Skips work-specific tools
Environment No work proxy configuration
Config files Excludes .codex.work/ directory

Configuration Examples

Shell Configuration

In dot_zshrc.tmpl:

{{ if .machine.isWork }}
# Work-specific settings
export JIRA_PROJECT="TEAM"
alias standup='open "https://meet.google.com/xxx-xxxx-xxx"'
{{ end }}

Path Configuration

In dot_config/zsh/conf.d/00-path.zsh.tmpl:

{{ if .machine.isWork }}
# Work tools path
typeset -U path
path=(
    "$HOME/.work-tools/bin"
    $path
)
{{ end }}

Package Installation

In run_onchange_before_install-packages-darwin.sh.tmpl:

# npm globals - work only
{{ if .machine.isWork }}
npm install -g @openai/codex
{{ end }}

Codex Configuration

In dot_codex.work/private_config.toml.tmpl (only applied on work machines):

[api]
base_url = "{{ .codex.baseUrl }}"

File Exclusion

The .chezmoiignore file excludes work-specific files on personal machines:

{{ if not .machine.isWork }}
.codex.work/
{{ end }}

This means:

  • Work machines: .codex.work/ directory is applied
  • Personal machines: .codex.work/ directory is completely ignored

Available Profile Variables

Variable Type Description
.machine.type string "work" or "personal"
.machine.isWork bool true if work machine
.machine.isPersonal bool true if personal machine

Combining with OS Detection

Profiles work alongside OS detection:

{{ if and .machine.isWork .machine.isDarwin }}
# Work Mac specific
{{ end }}

{{ if and .machine.isPersonal .machine.isLinux }}
# Personal Linux specific
{{ end }}

Adding New Profile-Specific Configuration

1. Add to Template File

{{ if .machine.isWork }}
# Your work-specific config here
{{ end }}

2. Add Conditional File Inclusion

In .chezmoiignore:

{{ if not .machine.isWork }}
path/to/work-only-file
{{ end }}

3. Add New Variable (Optional)

In .chezmoi.toml.tmpl:

{{- $workTool := "" -}}
{{- if eq $machineType "work" -}}
{{-   $workTool = promptStringOnce . "work.tool" "Work tool URL" "https://default.url" -}}
{{- end -}}

[data.work]
    tool = {{ $workTool | quote }}

Checking Your Current Profile

# View all template data including profile
chezmoi data | grep -A5 '"machine"'

# Or just the type
chezmoi execute-template '{{ .machine.type }}'

Example output:

"machine": {
    "type": "work",
    "isWork": true,
    "isPersonal": false,
    ...
}

Switching Profiles

To switch a machine's profile:

  1. Edit the config:

    $EDITOR ~/.config/chezmoi/chezmoi.toml

  2. Change the type:

    [data.machine]
    type = "personal"  # or "work"

  3. Re-apply:

    chezmoi apply

  4. Reload shell:

    exec zsh
