Jau Support Library (C++, Java,
...)
Git Repository
This project's canonical repositories is hosted on Gothel Software.
Goals
This project aims to provide general C++ collections, algorithms and
utilizies inclusive utilizities for a Java JNI binding.
This project was extracted from Direct-BT to
enable general use and enforce better encapsulation.
API Documentation
Up to date API documentation can be found:

C++
API Doc.

Examples
See Direct-BT C++
API Doc.
Supported Platforms
C++17 and better.
Building Binaries
It is advised to include this library into your main project, e.g. as
a git-submodule.
Then add jaulib/include/ to your include-path and also add
the source files under jaulib/src/ into your build recipe.
This library's build recipe are functional though, but currently only
intended to support unit testing and to produce a Doxygen API doc.
The project requires CMake 3.13+ for building and a Java JDK >=
11.
Installing build dependencies on Debian (10 or 11):
apt install git
apt install build-essential g++ gcc libc-dev libpthread-stubs0-dev 
apt install libunwind8 libunwind-dev
apt install openjdk-11-jdk openjdk-11-jre
apt install cmake cmake-extras extra-cmake-modules
apt install doxygen graphviz
For a generic build use:
CPU_COUNT=`getconf _NPROCESSORS_ONLN`
git clone https://jausoft.com/cgit/jaulib.git
cd jaulib
mkdir build
cd build
cmake -DBUILDJAVA=ON -DBUILDEXAMPLES=ON -DBUILD_TESTING=ON ..
make -j $CPU_COUNT install test doc
The install target of the last command will create the include/ and
lib/ directories with a copy of the headers and library objects
respectively in your build location. Note that doing an out-of-source
build may cause issues when rebuilding later on.
Our cmake configure has a number of options, cmake-gui or
ccmake can show you all the options. The interesting ones are
detailed below:
Changing install path from /usr/local to /usr
-DCMAKE_INSTALL_PREFIX=/usr
Building debug build:
-DDEBUG=ON
Building debug and instrumentation (sanitizer) build:
-DDEBUG=ON -DINSTRUMENTATION=ON
Using clang instead of gcc:
-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++
Cross-compiling on a different system:
-DCMAKE_CXX_FLAGS:STRING=-m32 -march=i586
-DCMAKE_C_FLAGS:STRING=-m32 -march=i586
To build Java bindings:
-DBUILDJAVA=ON
To build documentation run:
make doc
Changes
1.0.0

First stable release (TODO)

0.3.0

TODO
Finalized jau::cow_darray and its iterator API. All write API
entries were added to the mutable iterator.
Introduce jau::callocator for jau::darray to support realloc instead
of alloc, copy and dtor
Passed gcc-10, gcc-11, clang-9 and clang-11
Passed detailed cow_iterator test.
jau::cow_vector is marked deprecated, as only jau::cow_darray can
give certain guarantees using jau::darray
jau::cow_vector is aligned to jau::cow_darray and also uses
jau::cow_ro_iterator and jau::cow_rw_iterator
Added jau::darray and jau::cow_darray (using jau::cow_ro_iterator
and jau::cow_rw_iterator)
Test: Using imported Catch2 (v3-devel) for C++ unit testing
Reduced ringbuffer to single implementation, adding
move-operations
Added basic_types.hpp: 'to_decimal_string(..)' implementing
DecString() inlines.
Use nsize_t and snsize_t where appropriate for smaller
footprint
Have ringbuffer's Size_type parameterized
Bugfixes and added cow_array

0.2.1

Added cow_vector and sc_atomic_critical
Passed GCC all warnings, compile clean
Passed GCC sanitizer runtime checks
Passed valgrind's memcheck, helgrind and drd validating no memory
leak nor data race or deadlock using dbt_scanner10
Added native de-mangled backtrace support using libunwind
and and abi::__cxa_demangle

0.1.0

Extraction from Direct-BT
