hermes - 💡(How to fix) Fix [Bug][Regression]: Shift+Enter / Option+Enter submit prompt instead of inserting newline on Hermes CLI (not --tui) since 0.13.0 [2 comments, 2 participants]

Description

Shift+Enter and Option+Enter in Hermes CLI no longer insert newlines as of Hermes 0.13.0 onwards. This worked correctly in 0.12.0 but is broken on latest main.

Reproduction Steps

1. Run hermes in Warp terminal (no tmux/screen)
2. Type "hello"
3. Press Shift+Enter
4. The prompt "hello" is submitted immediately instead of cursor moving to a new line

Expected Behavior

Shift+Enter inserts a newline so that multi-line input can be composed directly in the CLI.

Actual Behavior

Shift+Enter submits the prompt (same behavior as plain Enter). Option+Enter behaves the same way.

Additional Info

• Option+Enter has the same broken behavior (submits instead of inserting newline)
• Esc then Enter still works as a workaround for inserting newlines
• Pasting multi-line text works fine (not a bracketed-paste issue)
• This is a regression: Shift+Enter worked correctly in 0.12.0

Environment

• Terminal: Warp (latest)
• Hermes version: latest main (0.13.0+)
• OS: macOS
• No tmux / screen
