Dear PDL folks, PDL 2.037 has just been uploaded to CPAN. Key features since the last announcement:
* New type qualifiers for pp_def Pars: “real” and “complex”, motivated by PDL::FFTW3 so it can return the real or complex version of the input floating-point data type (so “real” = cfloat->float, “complex” = float->cfloat, etc) as necessary * Bad value support is now always on, and no longer configurable to off, which simplified a fair bit of code * To help with maximum reproducibility, support for ~/.perldl.conf has been removed (and the whole perldl.conf will go away in due course) * pthread detection now works better, and works on MacOS and Windows * GenericTypes in pp_def functions defaults if not specified to only the real datatypes, for backwards-compatibility; functions have to “opt in” by specifying complex datatypes * The Proj4 modules work again, by using the CPAN Alien::Proj4 module – needed because general Linux distributions now package versions of proj that are not compatible with v4 anymore * Makefile.PL only prints when things don’t work/aren’t available, which makes developing nicer As usual, please give it a try and let me/us know of any problems. Next steps: * I intend to permanently enable the “badval per pdl” feature, and also incorporate the ability to use NaN as the badvalue, so those two configuration options will also disappear * I intend to stop calling PDL objects “piddles”, because that’s terribly unclear what it actually means, and update all the docs to call them “ndarrays” * Similarly, I intend to rename “threading” to “broadcasting” to eliminate unnecessary confusion * oodler577 on the #pdl channel is helping towards PDL supporting OpenMP * Better integration of native complex numbers Thoughts welcome on any and all of the above! Best regards, Ed
