Description

Summary

This PR adds support for Printerhive.com as a new print host option in OrcaSlicer. Users can now upload G-code files directly to Printerhive.com using their host URL and API key.

What this PR addresses

Adds Printerhive.com as a new print host type
Implements connection testing via GET request to user-provided host URL
Implements file upload via POST request to user-provided host URL
Supports automatic Device tab navigation after successful upload with custom URL display

New features

Printerhive Print Host: New print host option available in printer settings
Simple Configuration: Only requires host URL and API key (X-Api-Key header)
Dynamic URL Generation: After upload, automatically generates display URL by:
- Replacing /orcaslicer/ with /orcaslicer-print/ in the host URL
- Appending /file_uuid from upload response
- Adding API key as query parameter (?api_key=...)
Device Tab Integration: When "Switch to Device tab after upload" is enabled, automatically:
- Switches Device tab from MonitorPanel to PrinterWebView
- Loads the generated Printerhive URL with API key

Technical details

Test endpoint: GET request to user-provided host URL (success if HTTP 200)
Upload endpoint: POST request to user-provided host URL with multipart form data
Authentication: Uses X-Api-Key header (same as OctoPrint)
Response parsing: Extracts file_uuid from JSON response after upload
Thread safety: Uses CallAfter() for GUI operations from HTTP callback thread

Files changed

src/libslic3r/PrintConfig.hpp - Added htPrinterhive enum value
src/libslic3r/PrintConfig.cpp - Registered printerhive in enum mapping and labels
src/slic3r/Utils/Printerhive.hpp - New header file with Printerhive class declaration
src/slic3r/Utils/Printerhive.cpp - New implementation file with test() and upload() methods
src/slic3r/Utils/PrintHost.cpp - Added Printerhive to print host factory
src/slic3r/CMakeLists.txt - Added Printerhive.cpp to build configuration

Breaking changes

None. This is a purely additive change that does not affect existing functionality.

Dependencies

Uses existing HTTP infrastructure (Http.hpp)
Uses existing GUI components (MainFrame, PrinterWebView)
Uses nlohmann/json for response parsing

Screenshots

Tests

Manual testing performed:

✅ Added Printerhive as print host with host URL and API key
✅ Tested connection using "Test" button - verified GET request returns HTTP 200
✅ Uploaded G-code file - verified POST request succeeds and receives file_uuid in response
✅ Verified URL generation: /orcaslicer/ → /orcaslicer-print/ + /file_uuid + ?api_key=...
✅ Verified Device tab switch after upload when "Switch to Device tab after upload" is enabled
✅ Verified PrinterWebView loads with correct URL and API key in query parameter
✅ Tested with various host URL formats (with/without trailing spaces)
✅ Tested error handling for invalid JSON responses

Test cases:

Connection test: GET request to host URL, expects HTTP 200
File upload: POST request with multipart form data, expects JSON response with file_uuid
URL generation: Correctly transforms host URL and appends file_uuid and API key
Device tab navigation: Correctly switches to PrinterWebView and loads URL
Thread safety: GUI operations properly executed in main thread via CallAfter()

Edge cases handled:

Empty or missing file_uuid in response (URL generated without file_uuid)
Empty API key (URL generated without query parameter)
Host URL with trailing spaces (automatically trimmed)
Invalid JSON response (graceful error handling with warning log)
