Detailed Description

The CSV dialect DiFfRG reads and writes.

The same rules are implemented by the analysis-side readers in julia/src/io/csv.jl and python/DiFfRG/file_io/csv.py, so a file written by CsvOutput loads identically in all three.

Data cells hold numbers only and are parsed with std::from_chars, which is locale-independent. A cell that is empty or does not parse becomes NaN rather than raising, so a run that wrote an inf or left a gap still loads and the gap stays visible in the data. Header names may be quoted in the RFC-4180 sense, which is the only way a name can contain the separator. Rows whose field count differs from the header are skipped. Comment lines, blank lines, a UTF-8 BOM and CRLF line endings are all tolerated.
