Instance Method Details

#collect_search_terms ⇒ Object

Prompts for search terms via a multiline write block. Returns an empty array if the user declines.

def collect_search_terms
  return [] unless confirm!('Add search terms?')

  raw = prompt!(Gum.write(header: 'Put one search term per line', prompt_style: UI::PROMPT_STYLE, header_style: UI::PROMPT_STYLE))
  raw.to_s.lines.map(&:chomp).reject(&:empty?)
end

#confirm!(text) ⇒ Object

Wraps Gum.confirm and checks $?.exitstatus for 130 (Ctrl+C). Gum.confirm uses system() which swallows SIGINT and returns false, making it indistinguishable from the user answering “no” — except that $? records the child’s exit code 130. SIGINT can also raise Interrupt in Ruby before $? is read.

def confirm!(text)
  result = Gum.confirm(text, prompt_style: UI::PROMPT_STYLE)
  raise WizardInterrupted if result.nil?
  raise WizardInterrupted if $CHILD_STATUS.respond_to?(:exitstatus) && $CHILD_STATUS.exitstatus == 130

  result
rescue Interrupt
  raise WizardInterrupted
end

#list_confirm!(label, rows, headers, question) ⇒ Object

Renders a table of collected items and asks a follow-up question, without a border.

def list_confirm!(label, rows, headers, question)
  table = TableFormatter.render(rows, headers: headers)
  confirm!("Current #{label}s:\n\n#{table}\n\n#{question}")
end

#optional_prompt(question) ⇒ Object

Confirms a question then collects a value via the block, or returns nil if declined.

def optional_prompt(question)
  yield if confirm!(question)
end

#prompt!(value) ⇒ Object

Returns the value if non-nil; raises WizardInterrupted otherwise. Gum.choose / .input / .filter / .write return nil on Ctrl+C.
