* Finilize version 1.0.4 (version numbers, copyrights and such rubbish).
- replaced the Derivative() function by a more resonable fderivative class; to see it in action, try "series(abs(x),x==0,3)" and "series(abs(x),x==y,3)" in ginsh with previous GiNaC releases and with this one - add::eval() throws an exception when the first term is non-commutative and the overall_coeff is non-zero - small fixes to print_tree output of indexed objects - ncmul::expand() now actually does expand something like "(dirac_gamma(mu)+1) *dirac_gamma(nu)" correctly (but the change to add::eval() should make this a "can't happen" case) - moved ToString() to tostring.h (fewer header dependencies) - ALL YOUR "BASES CLASSES" ARE BELONG TO US
* color.cpp: remove duplicated default args. * numeric.cpp: insert some missing cln:: namespace decls. Why did this ever work? * structure.cpp, structure.h: adjust to the new print scheme.
- added skeleton implementation of color and clifford classes (don't bother trying it, it doesn't work yet) - some macros in utils.h (DEFAULT_*) provide shorthands for implementing many required class member functions
* ginac/registrar.h: dtor is inlined now. * ginac/basic.h, ginac/ex.h: removed INLINE_FOO_CONSTRUCTORS and hand-inlined stuff instead, since the macros turned out to get in the way while fine-tuning the inlining. * ginac/utils.h: if 'long long' works, use that one for computing the hash value instead of floating point tricks. 2 Reasons: on Intel the assembler is terrible and slow otherwise, 'long long' will appear in C++ anyways when they adapt to the C99 standard. * Several other small performance tweaks. * ginac/constant.cpp: (constant::calchash()) implement, caring for serial. * ginac/function.pl (function::calchash()): implement, caring for serial. * ginac/expairseq.cpp: honor coeff's hash value. * ginac/pseries.cpp: (pseries::power_const()) fix problems with zero pseries. * Added several pounds of in-source documentation in doxygen style.
GINAC_DECLARE_REGISTERED_CLASS declares duplicate() and compare_same_type(), GINAC_IMPLEMENT_REGISTERED_CLASS implements duplicate()
the destructor, copy constructor, and assignment operator (which were the same for all subclasses of basic, with very few exceptions) are now included in the GINAC_IMPLEMENT_REGISTERED_CLASS macro; the GINAC_DECLARE_REGISTERED_CLASS macro also defines these (and other common) member functions
removed the "some_*" and "typeid_*" definitions since we are using our own RTTI for quite some time now
- See if __GNUC__ < 2.97 before using std::vector<..,malloc_alloc>. Sorry, there is no way having this depend on whether we are setting up Cint or not because the malloc_alloc goes into the mangled signature and the result won't link if one tries to be more clever. It really sucks. Let's all just pray Masaharu throws away that old STL implementation really soon now. (Jeez, he still calls this old junk 'reference'!) - Bumped up a few dates. :-)
- Inserted some more std:: to make it compile under GCC2.96.
- indentation is now done with tabs - printtree() prints the class names as known to the registrar, not the (mangled) class names from typeid().name()
- Derivatives are now assembled in a slightly different manner (i.e. they 'look' different on first sight). Under certain circumstances this can result in a dramatic speedup because it gives hashing a better chance, especially when computing higher derivatives. - Series expansion accepts an additional bool argument now, telling it whether branch cuts are to be honored (as Maple does it) or not (as Mathematica does it). It defaults to true (i.e. the Maple way). - Many series expansions of built-in functions have been reengineered. - The Dilogarithm (Li2) now has floating point evaluation, derivative and a proper series expansion. - Namespace 'std' cleanly disentangled, as demanded by ISO/EIC 14882-1998(E). - Some helpers updated from upstream.
- Renamed flag NO_GINAC_NAMESPACE to NO_NAMESPACE_GINAC because of m4. - Made configure check for cint and makecint and call makecint to dump out cint/Makefile.cint, which will later be called by cint/Makefile. See configure option --with-cint. - Added some documentation about GiNaC-cint (e.g. a manpage). - All dummies in subdir cint/ are created by cint/dummies.pl now, removed older stuff.
- building GiNaC in a separate directory now works
- changed all instances of "foo const &/*" to "const foo &/*" - changed function arguments like "int const" to a simple "int"
- made nops() return unsigned instead of int - changed dates in copyright notices
#ifndef around namespace GiNaC { }
- put everything in "GiNaC" namespace - converted some macros into inline functions - split debugmsg.h into assertion.h (public) and debugmsg.h (private)
- modified the comment blocks so the copyright message no longer appears in the reference manual (made by Doxygen)
- modified GiNaC headers to Alexander's liking
- enforced GiNaC coding standards :-)
- switched to automake build environment
