An new minor revision of the AsioHeaders package arrived at CRAN earlier today. Asio provides a cross-platform C++ library for network and low-level I/O programming. It is also included in Boost – but requires linking when used as part of Boost. This standalone version of Asio is a header-only C++ library which can be used without linking (just like our BH package with parts of Boost).
This minor update avoid use of (v)sprintf which CRAN now flags in r-devel (for all R builds), following the decision by Apple to deprecated it for macOS. Winston had notified me about email he had gotten for for his websocket package – also highlighting the issue for both iptools and ipaddress. As the issue ticket dialog shows I was initially a little hamfisted about replicating, falsely thinking I would need an updated compiler. But this really is ‘just’ a change in r-devel once again scanning shared libraries for symbols now warned about. Upstream has newer minor releases but they did not yet cover this; however I found a commit mentioning Xcode and snprint from three days ago which I essentially ported. We needed one more change, and that addressed the issue in websocket. But as it is good to increase the number of random acts of kindness, I also looked into iptools and ipaddress as CRAN has its eyes on them too for this. Turned out they needed simple and limited changes from sprint to snprintf so made those and sent them PRs: iptools PR #42 and ipaddress PR #79.
The short NEWS entry for AsioHeaders follows.
Changes in version 1.22.1-2 (2022-12-07)
- Switch a handful of upstream
(v)sprintuses to(v)snprintf.
Thanks to my CRANberries, there is also a diffstat report relative to the previous release.

An updated version of the AsioHeaders package arrived at CRAN yesterday (in one of those pleasant fully-automated uploads and transitions). Asio provides a cross-platform C++ library for network and low-level I/O programming. It is also included in Boost – but requires linking when used as part of Boost. This standalone version of Asio is a header-only C++ library which can be used without linking (just like our BH package with parts of Boost).
This release brings a new upstream version, following a two-year period without updated. This was tickled by OpenSSL 3.0 header changes as seen in a package using both AsioHeaders and OpenSSL.
Changes in version 1.22.1-1 (2022-06-14)

An updated version of the AsioHeaders package arrived on CRAN today (after a we days of “rest” in the incoming directory of CRAN). Asio provides a cross-platform C++ library for network and low-level I/O programming. It is also included in Boost – but requires linking when used as part of Boost. This standalone version of Asio is a header-only C++ library which can be used without linking (just like our BH package with parts of Boost).
This release brings a new upstream version. Its changes required a corresponding change in one of (only) three reverse depends which delayed the CRAN admisstion by a few days.
Changes in version 1.16.1-1 (2020-06-28)
Upgraded to Asio 1.16.1 (Dirk in #5).
Updated README.md with standard set of badges
Via CRANberries, there is a diffstat report relative to the previous release.

This release corresponds to a minor upstream update, and is only the second update ever. It may help overcome one santizer warning which David Hall brought to my attention. We tested this version against all reverse depends (which was easy enough as there are only three).The NEWS entry follows.
Changes in version 1.12.2-1 (2020-03-11)

A first update to the AsioHeaders package arrived on CRAN today. Asio provides a cross-platform C++ library for network and low-level I/O programming. It is also included in Boost – but requires linking when used as part of Boost. This standalone version of Asio is a header-only C++ library which can be used without linking (just like our BH package with parts of Boost).
This release is the first following the initial upload of version 1.11.0-1 in 2015. I had noticed the updated 1.12.1 version a few days ago, and then Joe Cheng surprised me with a squeaky clean PR as he needed it to get RStudio’s websocket package working with OpenSSL 1.1.0.
I actually bumbled up the release a little bit this morning, uploading 1.12.1 first and then 1.12.1-1 as we like having a packaging revision. Old habits die hard. So technically CRAN, but we may clean that up and remove the 1.12.1 release from the archive as 1.12.1-1 is identical but for two bytes in DESCRIPTION.
The NEWS entry follow, it really is just the header update done by Joe plus some Travis maintenance.
Changes in version 1.12.1-1 (2018-09-10)
Upgraded to Asio 1.12.1 (Joe Cheng in #2)
Updated Travis CI support via newer run.sh
Via CRANberries, there is a diffstat report relative to the previous release, as well as this time also one between the version-corrected upload and the main one.

Making it easier to use C++ in R has been a really nice and rewarding side effect of the work on Rcpp. One really good idea came from something Jay Emerson, Michael Kane and had I kicked about for way too long: shipping Boost headers for easier use by R and CRAN packages (such as their family of packages around bigmemory). The key idea here is headers: Experienced C++ authors such as library writers can organise C++ code in such a way that one can (almost always) get by without any linking. Which makes deployment so much easier in most use cases, and surely also with R which knows how to set an include path.
So after years of "yes we really should", Jay deserves the credit for actually sitting down almost three years ago and creating the first version. So at the end of January 2013, we released BH version 1.51.0-0. By now the package is used fifty-four other CRAN packages --- clearly a much stronger uptake then we ever expected. I took over maintenance at some point, and we are currently in-line with the most recent Boost release 1.60.0.
But some people were always lusting after (some) parts of Boost which also require linking. For some libraries (such as Boost.Date_Time in my RcppBDT package) you can set a #define to not require linking (and forego some string formatting or parsing we get from R anyway). Some others are trickier; Boost Regex is one example. I do not think you can use it without linking (but then C++11 helps and finally brings regular expression in the default library).
Another library which the systems / network programmers at work would frequently rely upon is Boost.Asio, a cross-platform C++ library for network and low-level I/O programming. It was already used on CRAN by the iptools package by Bob Rudis and Oliver Keyes which shied away from building on Windoze (while 'doze and Boost do get along, but the CRAN system makes it a little more involved).
A couple of days ago, I somehow learned that the Asio library actually comes in two flavours: the well-known Boost.Asio (requiring linking), and also as a header-only standalone library! Well, well, well -- so I ran that by Bob and Oliver asking if that would be useful. And the response was a resounding and pretty much immediate Hell, Yes!.
So I wrapped it in a package, told Bob about it, who tested it and gave the thumbs up. And after a slightly longer-than-usual on-boarding, the package is now on CRAN. As network (and systems) programming is not entirely uncommon even at CRAN, I hope that this package may find a few more use cases. A new version of iptools should be forthcoming "shortly", including for the first time a Windows build thanks to this package. The indefatigable Martin Morgan already spotted our GitHub repo and scored the first fork.
