<p>Big news: RcppTOML now works on Windows too!</p>
<p>This package had an uneventful 2016 without a single update. Release 0.0.5 had come out <a href="http://dirk.eddelbuettel.com/blog/2015/12/19#rcpptoml_0.0.5">in late 2015</a> and we had no bugs or issues to fix. We use the package daily in production: a key part of our parameterisation is in <a href="https://github.com/toml-lang/toml">TOML</a> files</p>
<p>In the summer, I took one brief stab at building on Windows now that R sports itself a proper C++11 compiler on Windows too. I got stuck over the not-uncommon problem of incomplete POSIX and/or C++11 support with MinGW and g++-4.9. And sadly ... I appears I wasn't quite awake enough to realize that the missing functionality was right there exposed by <a href="http://dirk.eddelbuettel.com/code/rcpp.html">Rcpp</a>! Having updated that date / datetime functionality <a href="https://github.com/RcppCore/Rcpp/commit/e0d480715008a6b4d3ad10eea2fb7cc9d1827871">very recently</a>, I was in a better position to realize this when <a href="https://github.com/dpastoor">Devin Pastoor</a> asked <a href="https://github.com/eddelbuettel/rcpptoml/issues/5">two days ago</a>. I was able to make a quick suggestion which he tested, which I then refined ... here we are: <a href="http://dirk.eddelbuettel.com/code/rcpp.toml.html">RcppTOML</a> on Windows too! (For the impatient: CRAN has reported that it has built the Windows binaries, they should hit mirrors such as <a href="https://cloud.r-project.org/web/packages/RcppTOML/index.html">this CRAN package for RcppTOML</a> shortly.)</p>
<p>So what is this <a href="https://github.com/toml-lang/toml">TOML</a> thing, you ask? A file format, very suitable for configurations, meant to be edited by humans but read by computers. It emphasizes strong readability for humans while at the same time supporting strong typing as well as immediate and clear error reports. On small typos you get parse errors, rather than silently corrupted garbage. Much preferable to any and all of XML, JSON or YAML -- though sadly these may be too ubiquitous now. But <a href="https://github.com/toml-lang/toml">TOML</a> is making good inroads with newer and more flexible projects. The <a href="https://gohugo.io/">Hugo</a> static blog compiler is one example; the <a href="https://crates.io/">Cargo</a> system of Crates (aka &quot;packages&quot;) for the <a href="https://www.rust-lang.org/en-US/">Rust language</a> is another example.</p>
<p>The new release updates the included <a href="https://github.com/skystrife/cpptoml">cpptoml</a> template header by <a href="https://chara.cs.illinois.edu/sites/cgeigle/">Chase Geigle</a>, brings the aforementioned Windows support and updates the Travis configuration. We also added a NEWS file for the first time so here are all changes so far:</p>
