- for example,
string buffer = ...;
SubStrings<string> split;
{
auto colon = buffer.find(':');
if (colon != std::string::npos)
{
split = stringOps::splitSpace(buffer, colon+1);
}
}
Not really possible with a substr() since that would create a new
temporary which then disappears. Similarly awkward to split and
then scan for the ':' to decide how many to discard.
ENH: add pop_front() and pop_back() methods to SubStrings
- the content is trivial enough (a pair of iterators) and the total
number of elements is usually reasonable short so that removal of
elements is inexpensive
For example,
string buffer = ...;
auto split = stringOps::splitSpace(buffer);
if (!split.empty() && split[0].str() == "face")
{
split.pop_front();
}
- simplify compile/uncompile, reading, assignment
- implicit construct wordRe from keyType (was explicit) to simplify
future API changes.
- make Foam::isspace consistent with std::isspace (C-locale)
by including vertical tab and form feed
ENH: improve #ifeq float/label comparisons
- 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
- 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
