Gwf to scs improve

[RivaKing]

---

Important

Improves GWF-to-SCs translation with new command-line options and enhanced SCs file output handling in sc_builder_runner.cpp and sc_scs_writer.cpp.

• Behavior:
  • Added --gwf-to-scs and --gwf-output options in sc_builder_runner.cpp for translating GWF files to SCs.
  • Enhanced SCs file output in SCsWriter::Write() in sc_scs_writer.cpp to handle nodes, arcs, and contours more effectively.
• Functions:
  • PrintHelpMessage() in sc_builder_runner.cpp updated with new options for GWF-to-SCs translation.
  • SCsWriter::Write() refactored to improve node and arc processing, including handling of SCgLinks and image content.
  • Added SCsWriter::CollectNodes() to recursively gather nodes, including those in contours.
• Misc:
  • Included sc_scg_to_scs_types_converter.hpp in sc_scs_writer.cpp for type conversion.
  • Updated SCsWriter::SCgIdentifierCorrector methods for identifier correction.

1. sc-tools/sc-builder/src/sc_scs_writer.cpp:242

• Draft comment:
  The nested loop for attribute arc lookup could be optimized for performance if the element set is large.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 0% vs. threshold = 50% While the loop could potentially be optimized by using a different data structure, there's no evidence in the code that this is a performance bottleneck. The code already has an early break and the operation only happens for complex arcs. Without profiling data or clear evidence of performance issues, this seems like premature optimization. The comment could be valid if this code processes very large graphs where performance is critical. The current implementation is O(n) for each complex arc. However, the code appears to be part of a file writer/serializer which is likely not in a performance-critical path. The current implementation prioritizes readability and maintainability. The comment should be deleted as it suggests optimization without clear evidence of need, making it speculative rather than actionable.

Consider using std::cerr for error messages instead of std::cout.

Suggested change

	std::cout << "Error: Cannot open output file `" << outputFile << "`.\n";
	std::cerr << "Error: Cannot open output file `" << outputFile << "`.\n";

[ellipsis-dev]

Validate contentTypeStr before converting with std::stoi to avoid exceptions from malformed data.

[ellipsis-dev]

Sanitize fileName to prevent potential directory traversal issues when constructing file paths.

Suggested change

	std::string fileName = link->GetFileName();
	std::string fileName = std::filesystem::path(link->GetFileName()).filename().string();

[ellipsis-dev]

Consider refactoring the connector printing logic into a helper function to reduce code duplication.

[ellipsis-dev]

Consider splitting the lengthy Write() function into smaller helper functions to improve readability and maintainability.
