PDL 2.064 released

PDL 2.064 has just been released. Notable changes since 2.062:

pthreads should now be available on BSD systems
Support for signed and unsigned versions of all integers up to 64-bit, and real and complex long double
qsortvec* now work with badvalues as documented
wfits now handles RICE compression
NiceSlice now works correctly with comments and strings
rmpeg added, rpic and wpic work with multi-image PNM files
xvals etc return at least a double, avoiding problems with e.g. byte ndarrays
Improvements to $MACRONAME() handling including that arguments can now contain (balanced) brackets
The PROJ.4 interface has been updated to use the PROJ v6+ interface, finally
A zeroes() regression from 2.057_01 where it ignored the type of an input PDL has been fixed

The last dev-release showed FreeBSD 13 (the latest) failing to find “csinl” (complex long double sin). That is mandated by C99, so we won’t be doing configure probes for it. Please update your libm if this causes a problem, and your compiler (including clang <12.0.5) if it crashes on pdlcore.c.

Future plans, in something like intended order:

“loop fusion” techniques to maximise locality of computation, minimising data’s trips through the “straw” between CPU and main RAM
finish the independent C interface for making PDL usable from e.g. Python
use OpenCL or other means to also utilise GPUs if available

The IRC channel (#pdl on irc.perl.org) is a great virtual place to come and ask questions, or just watch the GitHub messages flow by.

As usual, please give the new PDL a try and report problems.

PDL 2.075 has just been released. Notable changes since 2.064: threading now called broadcasting (compat aliases created) fix when readdata functions return error (#356) RedoDimsCode can now use $SIZE(other_index) (#386) can now unify Code and BadCode into Code, and use PDL_IF_BAD() or #ifdef PDL_BAD_CODE add macros PDL_IF_GENTYPE_{REAL,INTEGER,UNSIGNED}(iftrue,iffalse) in Code fixes to PDL::NiceSlice including performance bug by monkey-patching Text::Balanced::extract_multiple Minuit and Slatec 64-bit safe bifuncs like Ops::plus no longer need explicit swap parameter As usual, please give the new PDL a try and report problems.

The last dev-release showed FreeBSD 13 (the latest) failing to find “csinl” (complex long double sin). That is mandated by C99, so we won’t be doing configure probes for it. In fact, the latest dev-release (2.068_05) does probe for the complex-long-double version of functions, and only uses the complex version if that is found, and also the tests check for complex versions of both `exp` and `log` before testing their behaviour. It seems the latest FreeBSD (14) has some different problem that is breaking its use of PROJ, but hopefully this is an improvement.	[reply] [d/l] [select]
