Rblpapi 0.3.15 on CRAN: Several Refinements

Version 0.3.16 of the Rblpapi package arrived on CRAN today. Rblpapi provides a direct interface between R and the Bloomberg Terminal via the C++ API provided by Bloomberg (but note that a valid Bloomberg license and installation is required).

This is the sixteenth release since the package first appeared on CRAN in 2016. It contains several enhancements. Two contributed PRs improve an error message, and extended connection options. We cleaned up a bit of internal code. And this release also makes the build conditional on having a valid build environment. This has been driven by the fact CRAN continues to builder under macOS 13 for x86_64, but Bloomberg no longer supplies a library and headers. And our repeated requests to be able to opt out of the build were, well, roundly ignored. So now the builds will succeed, but on unviable platforms such as that one we will only offer ‘empty’ functions. But no more build ERRORS yelling at us for three configurations.

The detailed list of changes follow below.

Changes in Rblpapi version 0.3.16 (2025-03-31)

• A quota error message is now improved (Rodolphe Duge in #400)

• Convert remaining throw into Rcpp::stop (Dirk in #402 fixing #401)

• Add optional appIdentityKey argument to blpConnect (Kai Lin in #404)

• Rework build as function of Blp library availability (Dirk and John in #406, #409, #410 fixing #407, #408)

Courtesy of my CRANberries, there is also a diffstat report for the this release. As always, more detailed information is at the Rblpapi repo or the Rblpapi page. Questions, comments etc should go to the issue tickets system at the GitHub repo.

RProtoBuf 0.4.24 on CRAN: Minor Polish

A new maintenance release 0.4.24 of RProtoBuf arrived on CRAN today. RProtoBuf provides R with bindings for the Google Protocol Buffers (“ProtoBuf”) data encoding and serialization library used and released by Google, and deployed very widely in numerous projects as a language and operating-system agnostic protocol.

This release brings an both an upstream API update affecting one function, and an update to our use of the C API of R, also in one function. Nothing user-facing, and no surprises expected.

The following section from the NEWS.Rd file has full details.

Changes in RProtoBuf version 0.4.24 (2025-03-31)

• Add bindings to EnumValueDescriptor::name (Mike Kruskal in #108)

• Replace EXTPTR_PTR with R_ExternalPtrAddr (Dirk)

Thanks to my CRANberries, there is a diff to the previous release. The RProtoBuf page has copies of the (older) package vignette, the ‘quick’ overview vignette, and the pre-print of our JSS paper. Questions, comments etc should go to the GitHub issue tracker off the GitHub repo.
