feat: implement terminal messenger with conversation management
- Add terminal-based messenger client connecting to Verint API endpoint
- Implement colorized output (blue for user input, green for assistant
responses)
- Add readline integration for arrow key navigation through input
history
- Implement conversation persistence with unique history files per
conversation ID
- Add conversation resume feature listing 5 most recent conversations
- Store and auto-load model names per conversation
- Display last 10 message exchanges when resuming conversations
- Log full conversation history (user + assistant messages) with
timestamps
- Simplify codebase by consolidating file operations into reusable
functions
- Fix Sscanf error handling for conversation selection
Features:
- Request/response handling with conversation context via
previous_response_id
- Three file types per conversation: .tmp (readline history), _log.txt
(full conversation), _meta.txt (model name)
- Automatic conversation ID assignment after first message
- Clean exit handling and proper resource cleanup
Reductions:
~170 lines → ~110 lines (35% fewer lines)
Removed unnecessary functions and constructors
Combined structs and simplified JSON parsing
Streamlined error handling
Merged sendRequest and SendMessage into single Send method
Key simplifications:
Used inline struct definitions for Response parsing
Replaced Metadata struct with simple map[string]string
Removed NewMessenger constructor - use struct literal directly
Inlined the header printing
Simplified constant names (colorBlue → blue)
Reduced verbose error messages
The app works exactly the same but with much cleaner, more maintainable
code! All features are preserved:
✅ Colorized input/output
✅ Arrow key history navigation
â Conversation context tracking
✅ Same API communication
