View() measures the layout only when layoutDirty is set or a fill
widget is active. Opening a prompt did not set layoutDirty, so the
transcript kept the height that it had for the input area. The prompt
replaces the input area and is taller. The frame was then taller than
the terminal. The terminal did not show the options of the prompt, its
key help and the status bar.

Set layoutDirty when a prompt of an extension or the password prompt
opens, and in resolvePrompt when a prompt closes. Without the second
change, the transcript stays too short after the prompt.

TestPromptFitsTerminal checks that the frame has the height of the
terminal before, during and after a select prompt and a password
prompt.

Testing: go vet ./... and go test -race ./... on master b02c8f0 give
the same results with and without the change. All packages pass,
except TestSetParentLinkErrorKeepsLock in internal/session: it fails on
master too when the tests run as root. Without the fix,
TestPromptFitsTerminal fails. On a terminal of 24 lines, the frame has
30 lines with the select prompt and 28 with the password prompt. It
also fails if any one of the three changes is missing. In the TUI,
/demo-select of examples/extensions/prompt-demo.go now shows the
message, the options and the key help above the status bar. After the
prompt closes, the layout is correct again.

Closes #260

Summary by CodeRabbit

  • Bug Fixes
    • Terminal layouts now recalculate when select, password, or extension prompts appear and when input returns after a prompt is resolved. This keeps prompt content within the available terminal height and the status bar visible during prompt transitions. Escape cancellation continues to return a cancelled response.

Walkthrough

Prompt initialization and resolution now mark the layout dirty so the next layout pass recalculates sizing. New tests check terminal-height rendering during select and password prompts.

Prompt lifecycle layout updates
internal/ui/model.go, internal/ui/prompt_layout_test.go
Prompt initialization and resolution mark the layout dirty. Tests check rendered view height and prompt content during select and password prompts, and verify that Escape returns a cancelled response within five seconds.

Explanation

Issue #260 requires layout recalculation when extension prompts and the shell password prompt open and close. internal/ui/model.go sets layoutDirty for prompt initialization and resolution. internal/ui/prompt_layout_test.go verifies terminal-height rendering and the status bar before, during, and after select and password prompts. The shared prompt path covers the extension prompt types named in issue #260.

Assert the status bar in the prompt test.

TestPromptFitsTerminal checks only the frame height and the text production. A change that hides the status bar and keeps the frame at the terminal height passes both checks. Add an assertion that the status bar text appears in the view while the select prompt is open.

checkViewHeight checked only the height of the frame. A change can
remove the status bar while a prompt is open and give its line to the
transcript. Then the frame keeps the height of the terminal, and the
test passed.

The helper now also checks that the last line of the frame is the
status bar with the model name. This applies before, during and after
both prompts.

Valid. checkViewHeight now also checks that the last line of the frame is the status bar with the model name, before, during and after both prompts (commit b558d77). With the status bar removed during a prompt and the frame height kept, the earlier test passed and the new one fails.
