Jul 1, 2025Monthly summary for 2025-07 for GreenBankObservatory/dysh focusing on delivering stable, user-friendly data summaries and solidifying build stability. Key work includes a refactor of the summary subsystem into distinct data processing (get_summary) and display (summary) paths, with safeguards to render summaries even if not the last operation in a cell. Added configurability for maximum rows and whether to display the index, enabling tailored views for different workflows. Implemented a dependency compatibility fix by pinning numpy to < 2 in pyproject.toml to maintain compatibility with upstream libraries. Updated documentation to clarify data generation workflow: README.md now specifies that GBTIDL is used to generate the input file (not both input and output files) and testdata README was aligned accordingly. All changes include targeted commits to support traceability and collaboration.
