- simplify structure.
- protect against nullptr when resetting memory streams
- make UIListStream swappable
- add uiliststream as an example of using a plain std::istream
- define regExp::results_type using SubStrings container for handling
groups. This makes a later shift to std::smatch easier, but changes
the regExp API for matching with groups. Previously had list element
0 for regex group 1, now list element 0 is the entire match and list
element 1 is regex group 1.
Old:
List<std::string> mat;
if (re.match(text, mat)) Info<< "group 1: " << mat[0] << nl;
New:
regExp::results_type mat;
if (re.match(text, mat)) Info<< "group 1: " << mat.str(1) << nl;
- can be used to handle when options become redundant, but it is
undesirable to treat its presence as an error. Can now tag it as
being ignored.
argList::ignoreOptionCompat({"oldOption", 1706}, true);
argList::ignoreOptionCompat({"oldBoolOpttion", 1706}, false);
command -oldOption xyz -oldBoolOpttion
- use succincter method names that more closely resemble dictionary
and HashTable method names. This improves method name consistency
between classes and also requires less typing effort:
args.found(optName) vs. args.optionFound(optName)
args.readIfPresent(..) vs. args.optionReadIfPresent(..)
...
args.opt<scalar>(optName) vs. args.optionRead<scalar>(optName)
args.read<scalar>(index) vs. args.argRead<scalar>(index)
- the older method names forms have been retained for code compatibility,
but are now deprecated
- now avoid Istream and token mechanism in favour of a simpler string
parser. This makes the code clearer, smaller, robuster.
- provide convenience ge/gt/le/lt static constructors for scalarRange
for using bounds directly with specifying via a string parameter.
- scalarRange, scalarRanges now follow the unary predicate pattern
(using an operator() for testing). This allows their reuse in
other contexts. Eg, for filtering operations:
myHash.filterValues(scalarRange::ge(100));
- remove unused scalarRanges methods that were specific to handling
lists of time values. These were superseded by timeSelector methods
several versions ago.
- required if there is no system openmp and libomp or libgomp are
only found in the clang hierarchy
STYLE: add some notes in the openmp rules.
- the _OPENMP macro is now used in low-level testing files
- The -rotate-angle option allows convenient specification of a
rotation about an arbitrary axis. Eg, -rotate-angle '((1 1 1) 45)'
- The -origin option can be used to temporarily shift the origin
for the rotation operations. For example,
-origin '(0 0 1)' -rotate-angle '((1 0 0) 180)'
for mirroring.
- include amount of free system memory in profiling, which can give an
indication of when swapping is about to start
- profilingSummary utility to collect profiling from parallel
calculations. Collects profiling information from processor
directories and summarize the time spent and number of calls as (max
avg min) values.
- split now optionally retains empty substrings.
Added split on fixed field width.
- Foam::name() now formats directly into string buffer, which a
removes one layer of copying and also avoids using a non-constexpr
in the temporary.
STYLE: explicit type narrowing on zero-padded output for ensight
- this makes them applicable to Foam::string, Foam::word etc
ENH: improvements to CStringList
- add strings() sublist variant which can be useful when handling
command arguments separately
- add construct from SubStrings.
- this provides a better typesafe means of locating predefined cell
models than relying on strings. The lookup is now ptr() or ref()
directly. The lookup functions behave like on-demand singletons when
loading "etc/cellModels".
Functionality is now located entirely in cellModel but a forwarding
version of cellModeller is provided for API (but not ABI) compatibility
with older existing user code.
STYLE: use constexpr for cellMatcher constants
- when dictionary keywords change between versions, the programmer
can use these compatibility methods to help with migration.
* csearchCompat, foundCompat, lookupEntryPtrCompat, lookupEntryCompat,
lookupCompat, lookupOrDefaultCompat, readIfPresentCompat, ...
They behave like their similarly named base versions, but accept an
additional list of older keyword names augmented by a version number.
For example,
dict.readIfPresentCompat
(
"key", {{"olderName", 1612}, {"veryOld", 240}},
myscalar
);
where 1612=OpenFOAM-v1612, 240=OpenFOAM-v2.4.x, etc.
- If the entry could be directly inserted: a pointer to the inserted entry.
- If a dictionary merge was required: a pointer to the dictionary that
received the entry.
- Return nullptr on any type of insertion failure.
This change is code compatible with existing code since it only alters
a bool return value to be a pointer return value.
- improved memory alignment reduces overhead for Int32 compilation
- added move/swap semantics
- made the type() readonly in favour of setVariant() to allow change
of variant within a particular storage representation.
Eg, STRING -> VERBATIMSTRING.
- the zero::null and one::null sub-classes add an additional null
output adapter.
The function of the nil class (special-purpose class only used for
HashSet) is now taken by zero::null.
- consistent with C++ STL conventions, the reverse iterators should
use operator++ to transit the list from rbegin() to rend().
The previous implementation used raw pointers, which meant that they
had the opposite behaviour: operator-- to transit from rbegin() to
rend().
The updated version only has operator++ defined, thus the compiler
should catch any possible instances where people were using the old
(incorrect) versions.
- updated forAllReverseIters() and forAllConstReverseIters() macros to
be consistent with new implementation and with C++ STL conventions.
- Instead of relying on #inputMode to effect a global change it is now
possible (and recommended) to a temporary change in the inputMode
for the following entry.
#default : provide default value if entry is not already defined
#overwrite : silently remove a previously existing entry
#warn : warn about duplicate entries
#error : error if any duplicate entries occur
#merge : merge sub-dictionaries when possible (the default mode)
This is generally less cumbersome than the switching the global
inputMode. For example to provide a set of fallback values.
#includeIfPresent "user-files"
...
#default value uniform 10;
vs.
#includeIfPresent "user-files"
#inputMode protect
...
value uniform 10;
#inputMode merge // _Assuming_ we actually had this before
These directives can also be used to suppress the normal dictionary
merge semantics:
#overwrite dict { entry val; ... }
- patterns only supported for the final element.
To create an element as a pattern instead of a word, an embedded
string quote (single or double) is used for that element.
Any of the following examples:
"/top/sub/dict/'(p|U).*" 100;
"/top/sub/dict/'(p|U).*'" 100;
"/top/sub/dict/\"(p|U).*" 100;
"/top/sub/dict/\"(p|U).*\"" 100;
are equivalent to the longer form:
top
{
sub
{
dict
{
"(p|U).*" 100;
}
}
}
It is not currently possible to auto-vivify intermediate
dictionaries with patterns.
NOK "/nonexistent.*/value" 100;
OK "/existing.*/value" 100;
- full scoping also works for the #remove directive
#remove "/dict1/subdict2/entry1"
- this increases the flexibility of the interface
- Add stringOps 'natural' string sorting comparison.
Digits are sorted in their natural order, which means that
(file10.txt file05.txt file2.txt)
are sorted as
(file2.txt file05.txt file10.txt)
STYLE: consistent naming of template parameters for comparators
- Compare for normal binary predicates
- ListComparePredicate for list compare binary predicates
- similar to word::validate to allow stripping of invalid characters
without triggering a FatalError.
- use this validated fileName in Foam::readDir to avoid problems when
a directory contains files with invalid characters in their names
- adjust rmDir to handle filenames with invalid characters
- fileName::equals() static method to compare strings while ignoring
any differences that are solely due to duplicate slashes
- more consistent naming:
* Versions that hold and manage their own memory:
IListStream, OListStream
* Versions that reference a fixed size external memory:
UIListStream, UOListStream
- use List storage instead of DynamicList within OListStream.
Avoids duplicate bookkeeping, more direct handling of resizing.
- The problem occurs when using atof to parse values such as "1e-39"
since this is out of range for a float and _can_ set errno to
ERANGE.
Similar to parsing of integers, now parse with the longest floating
point representation "long double" via strtold (guaranteed to be
part of C++11) and verify against the respective VGREAT values for
overflow. Treat anything smaller than VSMALL to be zero.
- these provide a similar functionality to string-streams, but operate
on a externally provided memory buffer which can be used to reduce
the amount of copying.
- classes were previously staged as part of the ADIOS community
repository.
- for convenience and symmetry with OStringStream
STYLE: void return value for stream rewind() methods
- this makes it easier to design bidirectional streams
- low-level beginRaw(), writeRaw(), endRaw() methods.
These can be used to directly add '()' decorators for serial output
or prepare/cleanup parallel buffers.
Used, for example, when outputting indirect lists in binary to avoid.
- used in various places to test if the input can be parsed as a
label/scalar, so warnings tend to flood the output.
- be more explicit when encountering range errors
