Summary

This pull request introduces enhancements to the chatbot configuration and user interface, focusing on improved customization and localization. The key changes include adding support for hiding and marking prompt variables as required, passing a customizable bot name to the chat input area, and updating translations to reflect this new functionality.

Chatbot Configuration Enhancements:

  • Updated PromptVariable type in web/models/debug.ts to include hide and required properties, enabling frontend customization for hiding variables and marking them as required.
  • Modified inputsForm in DebugWithMultipleModel to map hide and required properties from PromptVariable.

Chat Input Area Improvements:

  • Added a botName property to the ChatInputAreaProps type in web/app/components/base/chat/chat/chat-input-area/index.tsx, allowing the placeholder text in the chat input to dynamically include the bot's name. [1] [2]
  • Updated the placeholder in ChatInputArea to use the new botName property, enhancing user experience by personalizing the input field.

Localization Updates:

  • Updated the inputPlaceholder translation in multiple language files (e.g., de-DE, en-US, es-ES, etc.) to support dynamic insertion of the bot name using the {{botName}} placeholder. [1] [2] [3] [4] and others)

Integration with Chat Components:

  • Passed the bot name (appData?.site.title || 'Bot') to ChatInputArea in the Chat component and DebugWithMultipleModel component to ensure the bot name is used consistently across the application. [1] [2]
