"""Fix Notepad++ display and UI issues with automated corrections.
PORTMANTEAU PATTERN RATIONALE:
Instead of creating 2 separate tools (fix_invisible_text, fix_display_issue), this tool consolidates
display correction operations into a single interface. Prevents tool explosion (2 tools -> 1 tool) while maintaining
full functionality and improving discoverability. Follows FastMCP 2.14.1+ SOTA standards.
Supported Operations:
- Fix invisible or corrupted text display
- Resolve general display and UI rendering issues
Operations Detail:
**Text Visibility:**
- "fix_invisible_text": Restore visibility of text that appears invisible due to rendering issues
**Display Correction:**
- "fix_display_issue": General display problem resolution including refresh and redraw operations
Prerequisites:
- Windows OS with Notepad++ installed and running
- pywin32 package for Windows API access
- Active Notepad++ window (not minimized or hidden)
- User interface elements accessible via Windows API
Args:
operation (Literal, required): The display correction operation to perform. Must be one of: "fix_invisible_text", "fix_display_issue".
- "fix_invisible_text": Attempt to restore invisible text visibility
- "fix_display_issue": Perform general display refresh and correction
Returns:
Dictionary following FastMCP 2.14.1+ enhanced response patterns:
```json
{
"success": true,
"operation": "fix_invisible_text",
"summary": "Text visibility restored - window refreshed and focused",
"result": {
"actions_taken": [
"Window brought to foreground",
"Display refreshed",
"Text selection reset"
],
"window_handle": "0x00123456",
"attempts_made": 1
},
"next_steps": ["Check if text is now visible", "Try again if issue persists"],
"context": {
"operation_type": "display_correction"
}
}
```
**Success Response Structure:**
- success (bool): Operation success status
- operation (str): Display operation that was performed
- summary (str): Human-readable result summary
- result (dict): Display correction data (actions taken, window info, etc.)
- next_steps (list[str]): Suggested next actions
- context (dict): Additional operation context
**Error Response Structure:**
- success (bool): Always false for errors
- error (str): Error type (window_not_found, api_unavailable, etc.)
- operation (str): Failed operation
- summary (str): Human-readable error summary
- recovery_options (list[str]): Suggested recovery actions
Examples:
# Fix invisible text issue
result = await display_ops("fix_invisible_text")
# Returns: {"success": true, "summary": "Text visibility restored", "result": {...}, ...}
# Fix general display issues
result = await display_ops("fix_display_issue")
# Returns: {"success": true, "summary": "Display refreshed", "result": {...}, ...}
Errors:
**Common Errors:**
- "Windows API not available": pywin32 not installed or Windows API access failed
- "Notepad++ window not found": Notepad++ is not running or window is inaccessible
- "Window not accessible": Notepad++ window is minimized or hidden from Windows API
- "Display correction failed": Unable to perform requested display correction
**Recovery Options:**
- Install pywin32: `pip install pywin32`
- Ensure Notepad++ is running and visible (not minimized)
- Try bringing Notepad++ to foreground manually first
- Restart Notepad++ if display issues persist
- Check Windows permissions for UI automation access
