The NEWS file entry follows below:
0.2.3 2011-04-12
o Protect UINT64 and INT64 with '#ifdef RCPP_HAS_LONG_LONG' which
itself is valid with either g++ <= 4.4, or newer versions if the
-std=c++0x is used

RProtoBuf 0.2.2
Thanks to two patches by Murray Stokely, we
have a nice new minor release 0.2.2 of
RProtoBuf
out on
CRAN.
RProtoBuf
provides
GNU R
bindings for
the
Google Protobuf data encoding
library used and released by Google.
The NEWS file entry follows below:
0.2.2 2011-01-11
o Applied two patches by Murray Stokely which
- correct a typo preventing some functions from being called,
- add bounds checking in call to google protobuf library,
- add a new name method
- add a tiny unit test for the above
- add more graceful error handling
- add support for import patterns other than .proto$,
- add simple reading file that does not exist (exception) test
- add simple repeated field unit test
And courtesy of
CRANberries, here is

RProtoBuf 0.2.1
A fresh minor release of
RProtoBuf,
now at version 0.2.1, has appeared earlier today on
CRAN.
RProtoBuf
provides
GNU R
bindings for
the
Google Protobuf data encoding
library used and released by Google.
This releases extends the recent 0.2.0 release of RProtoBuf with a patch for raw bytes serialization which Koert Kuipers kindly contributed. This helps RProtoBuf for RPC communication where raw bytes are often a preferred form.
As always, there is more information at the RProtoBuf page which has a draft package vignette, a 'quick' overview vignette and a unit test summary vignette. Questions, comments etc should go to the rprotobuf mailing list off the RProtoBuf page at R-Forge.

RProtoBuf 0.2,0
A brand new and shiny release of
RProtoBuf,
now at version 0.2.0, arrived on
CRAN earlier today.
RProtoBuf
provides
GNU R
bindings for
the
Google Protobuf data encoding
library used and release by Google and others.
This is only the second release after 0.1-0 more than six months ago. Given that Rcpp is such a key ingedrient for RProtoBuf, and that Rcpp underwent so many exciting changes itself, Romain and I never got around to releasing new versions of RProtoBuf. This version is now much closer to the actual C++ API and fairly feature rich. We summarised a few of these new things in the presentation at useR! 2010.
There is more information at the RProtoBuf page; there is a draft package vignette, a 'quick' overview vignette and a unit test summary vignette. Questions, comments etc should go to the rprotobuf mailing list off the RProtoBuf page at R-Forge.

RProtoBuf 0.1-0
Romain uploaded our first release of
RProtoBuf
to CRAN yesterday.
RProtoBuf
provides bindings for
GNU R to the
Google Protobuf implementation.
Google Protobuf is (and I
quote) a way of encoding structured data in an efficient yet extensible
format that is used for almost all internal RPC protocols and file
formats at Google.
RProtoBuf had a funny start. I had blogged about the 12 hour passage from proof of concept to R-Forge project following the ORD session hackfest in October. What happened next was as good. Romain emailed within hours of the blog post and reminded me of a similar project that is part of Saptarshi Guha's RHIPE R/Hadoop implementation. So the three of us--Romain, Saptarshi and I---started emailing and before long it becomes clear that Romain is both rather intrigued by this (whereas Saptarshi has slightly different needs for the inner workings of his Hadoop bindings) and was able to devote some time to it. So the code kept growing and growing at a fairly rapid clip. Til that stopped as we switched to working feverishly on Rcpp to both support the needs of this project, and to implement ideas we had while working on this. That now lead to the point where Rcpp is maturing in terms of features, so we will probably have time come back to more work on RProtoBuf to take advantage of the nice templated autoconversions we now have in Rcpp. Oddly enough, the initial blog post seemed to anticipate changes in Rcpp.
Anyway --
RProtoBuf
is finally here and it already does a fair amount of magic based of code reflection
using the proto files. The Google documentation has a simple
example of a 'person' entry in an 'addressbook' which, when translated to R,
goes like this:
R> library( RProtoBuf ) ## load the package R> readProtoFiles( "addressbook.proto" ) ## acquire protobuf information R> bob <- new( tutorial.Person, ## create new object + email = "bob@example.com", + name = "Bob", + id = 123 ) R> writeLines( bob$toString() ) ## serialize to stdout name: "Bob" id: 123 email: "bob@example.com" R> bob$email ## access and/or override [1] "bob@example.com" R> bob$id <- 5 R> bob$id [1] 5 R> serialize( bob, "person.pb" ) ## serialize to compact binary format
There is more information at the RProtoBuf page, and we already have a draft package vignette, a 'quick' overview vignette and a unit test summary vignette.
More changes should be forthcoming as Romain and I find time to code them up. Feedback is as always welcome.
