Ruby regex in Yaml

I'm new to YAML and I'm experimenting with writing some tests for language translation. The idea being that I have a YAML file that has the English and Welsh versions of the same text. I was wondering how I might do the following use a regex within the string in the YAML?

Example:

I have this basic test:

#Gherkin
And I expect to see payment confirmation for "Dave"

#Step Def
    And /^I expect to see payment confirmation for "(.*?)"$/ do |user|
      expect(page).to have_text "Payment successful for #{user} - Reference: 000000"
end

YAML Entry:

"Payment successful for Dave reference: 000000"
 - welsh: "Taliad llwyddiannus ar gyfer Dave Cyfeirnod: 000000"

Could I parameterize Dave in that YAML entry as the test suite covers hundreds of users.

Thanks

If you want to interpolate text into YAML you will need to replace the words that you want to be interpolated with %{keyword} where the keyword is a key that will be used to indicate which data to interpolate there.

If you use Rails, you would use the t helper method as outlined in this section of the I18n guide.

# The YAML file
en:
  payment_succeeded: "Payment successful for %{first_name} reference: %{reference_number}"
wh: 
  payment_succeeded: "Taliad llwyddiannus ar gyfer %{first_name} Cyfeirnod: %{reference_number}"

# Rails Controller / View / Model
t(:payment_succeeded, first_name: 'Dave', reference_number: '000000')

If you want a pure ruby implementation you can use the Kernel::format method.

# The YAML file
# NOTE: This can be in any format, as long as you use %{keyword} in places where you want the data to be interpolated
translations:
  english: "Payment successful for %{first_name} reference: %{reference_number}"
  welsh: "Taliad llwyddiannus ar gyfer %{first_name} Cyfeirnod: %{reference_number}"

# Ruby
translations = YAML.load(File.read('translations.yaml'))
string = format(translations[:translations][:welsh], first_name: 'Dave', reference_number: '000000')

Hope this helps.
