This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "GiNaC -- a C++ library for symbolic computations". The branch, c++11 has been updated via ff4d880932862000fce73efc3fb6da49c8d63ed6 (commit) via dfaa3383381a37f871cdd8ae7b19db579dddd83d (commit) via 85f46b3d72dbafb6fe1fbb9bca32ec612cf8b480 (commit) from 9cd8ed658fbc4b8c50b40e1db770462526dfb806 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit ff4d880932862000fce73efc3fb6da49c8d63ed6 Author: Richard Kreckel <kreckel(a)ginac.de> Date: Sat Nov 7 22:24:29 2015 +0100 Use C++11 'nullptr' where applicable. commit dfaa3383381a37f871cdd8ae7b19db579dddd83d Author: Richard Kreckel <kreckel(a)ginac.de> Date: Sat Nov 7 13:23:26 2015 +0100 Remove C++89 workaround for closing angle brackets in nested templates. commit 85f46b3d72dbafb6fe1fbb9bca32ec612cf8b480 Author: Richard Kreckel <kreckel(a)ginac.de> Date: Sat Nov 7 13:03:05 2015 +0100 Remove 'discardable' option from ctors of container and derived classes. The whole idea of this was to allow the ctor to pilfer the data from the constructed-from object, which is precisely the move semantics which C++11 supports with rvalue references. ----------------------------------------------------------------------- Summary of changes: check/time_hashmap.cpp | 4 +-- doc/CodingStyle | 6 ++--- doc/examples/lanczos.cpp | 8 +++--- ginac/basic.h | 2 +- ginac/clifford.cpp | 14 +++++----- ginac/clifford.h | 2 +- ginac/color.cpp | 2 +- ginac/color.h | 2 +- ginac/constant.cpp | 6 ++--- ginac/constant.h | 2 +- ginac/container.h | 58 +++++++++++++++++++--------------------- ginac/ex.h | 4 +-- ginac/factor.cpp | 4 +-- ginac/function.cppy | 8 +++--- ginac/function.hppy | 4 +-- ginac/indexed.cpp | 6 ++--- ginac/indexed.h | 2 +- ginac/inifcns_nstdsums.cpp | 14 +++++----- ginac/ncmul.cpp | 14 +++++----- ginac/ncmul.h | 2 +- ginac/operators.cpp | 12 ++++----- ginac/polynomial/collect_vargs.h | 2 +- ginac/polynomial/normalize.h | 4 +-- ginac/power.cpp | 2 +- ginac/print.h | 4 +-- ginac/ptr.h | 4 +-- ginac/registrar.h | 2 +- 27 files changed, 94 insertions(+), 100 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
