Conditional variable export in chezmoi.<format>.tmpl throwing undefined error on chezmoi init

[robellegate]

I've been making the switch to chezmoi for my dotfiles, starting with my work configs, but I'm running into the same problem as #2414 where certain variables conditionally set are not available in later parts of the template.

Here's a slightly redacted snippet of my .chezmoi.yaml.tmpl file:

{{/* The following variables are only available within this template file */}}

{{/* boolean feature tags */}}
{{- $docker := false -}}{{/* true if this machine should have Docker installed */}}
{{- $ephemeral := false -}}{{/* true if this machine is ephemeral, e.g. a cloud or VM instance */}}
{{- $headless := false -}}{{/* true if this machine does not have a screen and keyboard */}}
{{- $remote := false -}}{{/* true if this machine is connected to via SSH */}}
{{- $work := true -}}{{/* true if this machine is used for work, changed from default of false for testing */}}
{{- "" -}}

# ... jumping down to a later part of the template

{{/* variables to set if the machine is used for work */}}
{{- if $work -}}
{{-   $artifactory_host := "artifactory.some-domain.name" -}}
{{-   $artifactory_base := printf "https://%s:443/artifactory" $artifactory_host -}}
{{-   $docker_base := "docker.some-domain.name:443" -}}
{{- end -}}

sourceDir: {{ .chezmoi.sourceDir | quote }}

data:
  # Here we "export" the variables, so we can access them outside this file
  name: {{ $name | quote }}
  email: {{ $email | quote }}

  {{- if $work -}}
  artifactory_host: {{ $artifactory_host | quote }}
  artifactory_base: {{ $artifactory_base | quote }}
  docker_base: {{ $docker_base | quote }}
  {{- end -}}

  docker: {{ $docker }}
  ephemeral: {{ $ephemeral }}
  headless: {{ $headless }}
  remote: {{ $remote }}
  work: {{ $work }}

When I run chezmoi init --source ~/src/git.some-domain.name/robellegate/dotfiles/home, I encounter the following error message:

chezmoi: template: chezmoi.yaml:61: undefined variable "$artifactory_host"

If I remove only the first {{- if $work -}} conditional, the chezmoi init command successfully evaluates the promptString init template functions not pictured but then throws this error:

chezmoi: /Users/robellegate/src/git.some-domain.name/robellegate/dotfiles/home/.chezmoi.yaml.tmpl: yaml: line 21: mapping values are not allowed in this context

The template works only after removing both {{- if $work -}} conditionals, but obviously this isn't desired when I'm trying to support using the same config for personal and work.

Maybe I can get the outcome I'm looking for by using .chezmoidata.<format> or a combination of .chezmoiignore and .chezmoitemplates, but I'm trying to keep it simple.

I'm using .chezmoi.toml.tmpl from twpayne/dotfiles and .chezmoi.yaml.tmpl from gametaro/dotfiles as reference in case there's some discrepancy between the TOML and YAML formats for .chezmoi.<format>.tmpl.

You must initialize these variables outside if statement, using :=. Then inside if you update the values with =.
