0.1.0

August 2012

Defines the fixed-width FIFFLIB primitives (fiff_int_t, fiff_float_t, fiff_byte_t, fiff_double_t, the DAU packed half-precision integer aliases, the Julian-day type, etc.) so that on-disk records preserve the exact byte layout documented by the FIFF specification regardless of host platform. It also publishes a handful of Eigen typedefs (MatrixDau16, MatrixShort) used by the matrix tag readers in FIFFLIB::FiffStream and a small set of empty-default sentinel objects (defaultMatrixXd, defaultQStringList, ...) that let callers express "no value provided" on optional arguments without relying on std::optional, matching the historical MATLAB-style signatures inherited from the MNE matlab toolbox.

Note: the leftover "Old fiff_type declarations - replace them" heading on the previous header line reflects an in-progress cleanup toward strongly typed C++ replacements; new code should prefer the class wrappers (FIFFLIB::FiffId, FIFFLIB::FiffChInfo, ...) over the legacy "Rec" struct aliases re-exported for backwards compatibility.
