📝 Walkthrough

Walkthrough

The dump command now supports a text format. Screen elements render as an indented hierarchy with references, descriptions, identifiers, and state annotations. The CLI prints non-empty text responses directly.

Changes

Text UI dump

Layer / File(s)	Summary
Screen element text formatter types/screen_text.go, types/screen_text_test.go	FormatText recursively renders screen elements with descriptions, references, identifiers, and state annotations. Tests cover nesting and text precedence.
Dump response selection commands/dump.go	The dump request documents json, text, and raw. Text dumps populate DumpUIResponse.Text; other non-raw dumps retain structured elements.
CLI text output cli/dump.go	The CLI prints non-empty text responses directly. Help text lists the text format.

Merge Risk: 🔵 Low · up to d7954

The new text dump format works for populated screens, but empty screens are returned as JSON rather than text. This is a bounded output-contract inconsistency that should be corrected before relying on text output in scripts.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Print empty text dumps as text output.

When --format text returns an empty UI tree, FormatText returns "". Line 32 then falls back to printJson, so the command returns JSON instead of the requested text format. Select the direct-output path from the requested format, not from whether the formatted text is non-empty.

Proposed fix

-		if dumpResponse, ok := response.Data.(commands.DumpUIResponse); ok && dumpResponse.Text != "" {
+		if dumpResponse, ok := response.Data.(commands.DumpUIResponse); ok && dumpUIFormat == "text" {
 			fmt.Print(dumpResponse.Text)
 			return nil
 		}

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	if dumpResponse, ok := response.Data.(commands.DumpUIResponse); ok && dumpResponse.Text != "" {
	if dumpResponse, ok := response.Data.(commands.DumpUIResponse); ok && dumpUIFormat == "text" {
	fmt.Print(dumpResponse.Text)
	return nil
