- code reduction, documentation, code stubs for spheroid (#1901)
- make searchableSurfaceCollection available as 'collection'
for consistency with other objects
ENH: add some scalar constants for .org compatibility (#1881)
Although it can very much be a moving target, it can prove partly
useful to have some compatibility constants/methods.
- The wholesale change of 'GREAT' -> 'great' etc (JAN-2018), makes
user coding for multiple versions problematic. When
COMPAT_OPENFOAM_ORG is defined, now define constants (aliases) named
as per the openfoam.org version. Values, however, remain identical.
- For type-safe dictionary value retrieval, we have the templated
get<> methods added around NOV-2018 and deprecated the lookupType
method.
The .org version followed suit in NOV-2019, but opted for renaming
the templated lookupType method as a templated 'lookup' method.
Using this is discouraged, but allowed when COMPAT_OPENFOAM_ORG is
defined.
- flips state while preserving the textual representation.
Eg, OFF <-> ON, YES <-> NO etc.
- fix test case to avoid triggering abort(), which we cannot try/catch
- provides a more direct means of generating a compound token without
an Istream
- add transferCompoundToken() without Istream reference
- mark more token methods as noexcept
- provides consistency with identity(label, label) and looks more
familiar than using labelRange::labels()
- relocates labelRange IO operators to IntRange
ENH: make sliceRange interators random access
STYLE: scalarRanges::match() instead of predicate operator
- returns a range of `int` values that can be iterated across.
For example,
for (const int proci : Pstream::subProcs()) { ... }
instead of
for
(
int proci = Pstream::firstSlave();
proci <= Pstream::lastSlave();
++proci
)
{
...
}
- returns a range of `int` values that can be iterated across.
For example,
for (const int proci : Pstream::allProcs()) { ... }
instead of
for (label proci = 0; proci < Pstream::nProcs(); ++proci) { ... }
- add reverse iterators and replace std::iterator
(deprecated in C++17) with full definitions
- simplify construction of iterators
- construct labelRange from a single single parameter.
This creates a (0,len) range.
- make basic constructors forms constexpr.
Remove unused size checks.
- Derive labelRange from new IntRange template class.
Allows reuse of base functionality with different integral sizes.
Deprecations:
- deprecate labelRange::valid() in favour of using
labelRange::empty() or the bool operator.
For example,
if (range) ... vs older if (range.valid()) ...
DEFEATURE: drop labelRange::null, scalarRange::null static variables
- turned out to be not particularly useful.
Can simply use constexpr contructor forms
DEFEATURE: drop labelRange::identity static method
- simply use the single-parameter constructor
- introduce WM_COMPILE_CONTROL variable to convey control information
into the build rules.
The convention (as per spack):
- '+' to select a feature
- '~' to deselect a feature
Eg, to select the gold linker, and disable openmp
(spaces are not required):
WM_COMPILE_CONTROL="+gold ~openmp"
CONFIG: accept FOAM_EXTRA_LDFLAGS for AMD, gold, Mingw linkers
CONFIG: generalize PROJECT_LIBS (-ldl used almost universally)
- makes it easier to use in combination with various 'New' selectors,
which mostly return an autoPtr.
ENH: add very simple FFT test
- basic sanity test that the library links properly
- previously hidden as Detail::[IO]FstreamAllocator, now exposed
directly as [io]fstreamPointer, which allows reuse for
std::ifstream, std::ofstream wrapping, without the additional
ISstream, OSstream layers.
These stream pointers have some characteristics similar to a
unique_ptr.
- restrict direct gzstream usage to two files (fstreamPointers.C,
gzstream.C) which improves localization and makes it simpler to
enable/disable with the `HAVE_LIBZ` define.
The HAVE_LIBZ define is currently simply hard-coded in the
Make/options.
If compiled WITHOUT libz support:
- reading gz files : FatalError
- writing gz files : emit warning and downgrade to uncompressed
- warn if compression is specified in the case controlDict
and downgrade to uncompressed
ENH: minor updates to gzstream interface for C++11
- support construct/open with std::string for the file names.
CONFIG: provisioning for have_libz detection as wmake/script
- naming similarity with autoPtr, unique_ptr and other containers.
For UPtrList derivatives, this is equivalent to the existing
operator(). The read-only variant is also equivalent to the
single-parameter 'set(label)' method.
With PtrList<T> list(...) :
const T* ptr = list.get(10);
if (ptr)
{
ptr->method();
}
vs.
if (list.set(10))
{
list[10].method();
}
For HashPtrTable there is only a read-only variant which is equivalent
to testing for existence and for value.
With HashPtrTable<T> hash(...) :
const T* ptr = list.get("key");
if (ptr)
{
ptr->method();
}
vs.
if (list.found("key"))
{
// Fails on null pointer!!
list["key"].method();
}
Use of get() is largely a matter of taste or local coding requirements
- forwarding like the emplace() method, but overwriting existing
entries as required
- propagate similar changes to HashPtrTable
For example, with HashPtrTable<labelList> table(...) :
With 'insert' semantics
table.emplace("list1", 1000);
vs
if (!table.found("list1"))
{
table.set("list1", new labelList(1000));
}
or
table.insert("list1", autoPtr<labelList>::New(1000));
Note that the last example invokes an unnecessary allocation/deletion
if the insertion is unsuccessful.
With 'set' semantics:
table.emplace_set("list1", 15);
vs
table.set("list1", new labelList(15));
The fakeError function object emits FatalError at different stages (or
does nothing), which is useful for testing purposes (issue #1779).
Can request errors from constructor, execute and write methods.
- with '&&' conditions, often better to check for non-null autoPtr
first (it is cheap)
- check as bool instead of valid() method for cleaner code, especially
when the wrapped item itself has a valid/empty or good.
Also when handling multiple checks.
Now
if (ptr && ptr->valid())
if (ptr1 || ptr2)
instead
if (ptr.valid() && ptr->valid())
if (ptr1.valid() || ptr2.valid())
- libs() singleton method for global library handling
- explicit handling of empty filename for dlLibraryTable open/close.
Largely worked before, but now be more explicit about its behaviour.
- add (key, dict) constructor and open() methods.
More similarity to dimensionedType, Enum etc, and there is no
ambiguity with the templated open().
- construct or open from initializer_list of names
- optional verbosity when opening with auxiliary table,
avoid duplicate messages or spurious messages for these.
- basename and fullname methods (migrated from dynamicCode).
- centralise low-level load/unload hooks
- adjust close to also dlclose() aliased library names.
- use simpler decomposeParDict in tutorials, several had old
'boilerplate' decomposeParDict
- use simpler libs () format
- update surface sampling to use dictionary format

ENH: add Test-EigenMatrix application
The new iterative eigen decomposition functionality is
derived from:
Passalacqua et al.'s OpenQBMM (openqbmm.org/),
which is mostly derived from JAMA (math.nist.gov/javanumerics/jama/).
- bundled of boolean values as a vector of 3 components with
element access using x(), y() and z() member functions.
It also has some methods similar to bitSet.
- Not derived from Vector or VectorSpace since it does not share very
many vector-like characteristics.
- support construct from initializer_list, which can help simplify
code with constant coefficients.
- add default constructor for polynomialFunction and Istream reading
to support resizable lists of polynomialFunction.
A default constructed polynomialFunction is simply equivalent to
a constant zero.
- no special IO handling for Polynomial required,
it is the same as VectorSpace anyhow.
- previously introduced `getOrDefault` as a dictionary _get_ method,
now complete the transition and use it everywhere instead of
`lookupOrDefault`. This avoids mixed usage of the two methods that
are identical in behaviour, makes for shorter names, and promotes
the distinction between "lookup" access (ie, return a token stream,
locate and return an entry) and "get" access (ie, the above with
conversion to concrete types such as scalar, label etc).
- Favour use of argList methods that are more similar to dictionary
method names with the aim of reducing the cognitive load.
* Silently deprecate two-parameter get() method in favour of the
more familiar getOrDefault.
* Silently deprecate opt() method in favour of get()
These may be verbosely deprecated in future versions.
- similar to the behaviour of std::ignore and consistent with the
no input / no output nature of nullObject. Similarly accept a
const reference for its Istream operator.
- make most nullObject methods constexpr
- mostly wraps std::chrono so can inline much of it, which is potentially
helpful when used for inner timings.
- add elapsedTime() method for direct cast to double and for
naming similarity with wall-clock method.
Potential breaking change (minor):
- clockValue construct with a bool parameter is now simply tagged
dispatch (value is ignored) and always queries the current clock
value. This avoids needless branching.
Since this constructor form has primarily been used internally (eg,
clockTime), breakages in user code are not expected.
- have printBuildInfo output to std::ostream
- removed extraneous include "stdFoam.H"
ENH: revert to pre-processor defines for hard-coded paths (#1712)
- redundant information, but more robust at run-time without relying
on initialization order
- less frequently used, but the information was previously inaccessible
under etcFiles.C.
Now exposed within the foamVersion namespace and defined under
<global.Cver> to improve configuration possibilities.
- simplified templating, which cleans up code and does not appear to
break any normal user coding.
ENH: unique_ptr instead of homegrown demand-driven handling.
