- EvioFile: keep scanning past a record with the last-record bit while another record header (magic word) follows. - Record.scan_events: when a record has no event index array, walk events by the length word of each event bank. - EvioFile.__del__: ignore BufferError when numpy views of the mmap are still alive. Before, these files showed 1 record and 0 events. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A local web page that decodes EVIO v6 files in the browser: file checks, occupancy, rate, charge and timing plots (file, ROC and channel level), and a structure tree down to single hit words. `pyevio web [DIR]` serves it with a folder browser on localhost. Also adds examples/fadc250_stream_to_parquet.py and docs/web_viewer.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- pyevio web -> pyevio gui (module pyevio/web -> pyevio/gui); the old
textual-based 'pyevio ui' command is kept as-is.
- Add --mode {stream,file} to 'pyevio gui'. Default 'stream' decodes CODA
streaming fADC250 time frames (0xFF60), the only tested format. 'file'
skips that decode in the browser and shows the structure tree only,
since file-based/triggered EVIO uses a different layout that isn't
validated yet. No changes to pyevio's core parsing code.
- Update README/docs/examples/pyproject.toml references accordingly.

Summary
Two commits:
1. Read CODA streaming files that set the last-record bit on every record
Some CODA streaming fADC250 files (e.g.
EC5_EC6_cosmics_may19_short.evio) set the last-record bit on every record and carry no event index array. pyevio previously reported 1 record and 0 events for them.EvioFile: keep scanning past a record with the last-record bit while another record header (magic word) follows.Record.scan_events: when a record has no event index array, walk events by the length word of each event bank.EvioFile.__del__: ignoreBufferErrorwhen numpy views of the mmap are still alive.tests/test_record_scanning.py.2.
