BDE 3.88.0: Production Release¶

Schedule¶

The BDE team announces that the BDE 3.88.0 production release was completed on Monday, Aug 23, 2021.

BDE 3.88.0 Highlights¶

Updates to Log Attribute Formatting¶

ball:RecordStringFormatter changes the behavior of the “%a” format specifier (added in BDE 3.71.0) , and introduces a “%av” format specifier (“av” for “Attribute Value”). Both affected attributes control the rendering of ball::ScopedAttribute(s).

The table below summarizes the changes:

For a log record having 2 scoped attributes:

name = “Smith”

number = 1

Format specifier	Old behavior	New behavior
%a	name=”Smith” number=1	name=”Smith” number=1
%a[name]	“Smith”	name=”Smith”
%a[bad]	bad=N/A	(empty)
%av[name]	unsupported	“Smith”
%av[bad]	unsupported	(empty)
%a[name] %a	“Smith” number=1	name=”Smith” number=1
%a[bad] %a	bad=N/A name=”Smith” number=1	name=”Smith” number=1

Note: the new format specifier %av[name] prints only the value of the scoped attribute if the attribute is present in the log record and prints nothing otherwise.

`balcl_commandline` Updates¶

This release features several small updates, mostly documentation, to balcl_commandline. No existing behavior has been changed.

The documented behavior of linked variables has been clarified.

Preconditions on the use of several accessors are now stated more explicitly.

To facilitate the testing of preconditions, new accessors have been added to balcl::CommandLine:

bool             hasOption(const bsl::string& name) const;
bool             hasValue (const bsl::string& name) const;
OptionType::Enum type     (const bsl::string& name) const;

and to balcl::CommandLineOptionsHandle:

int                index(const char *name) const;
OptionType::Enum   type (const char *name) const;
const OptionValue& value(const char *name) const;

template <class TYPE>
const TYPE& the(bsl::size_t index) const;
