./lang/R-cpp11, C++11 Interface for Rs C Interface

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.4.7, Package name: R-cpp11-0.4.7, Maintainer: pkgsrc-users

Provides a header only, C++11 interface to R's C interface. Compared
to other approaches 'cpp11' strives to be safe against long jumps from
the C API as well as C++ exceptions, conform to normal R function
semantics and supports interaction with 'ALTREP' vectors.

Log message:
(lang/R-cpp11) Updated 0.4.3 to 0.4.7

# cpp11 0.4.7

* Internal changes requested by CRAN to fix invalid format string tokens
  (@paleolimbot, #345).

# cpp11 0.4.6

* R >=3.5.0 is now required to use cpp11. This is in line with (and even goes
  beyond) the tidyverse standard of supporting the previous 5 minor releases of
  R. It also ensures that `R_UnwindProtect()` is available to avoid C++ memory
  leaks (#332).

* `cpp11::preserved.release_all()` has been removed. This was intended to
  support expert developers on R <3.5.0 when cpp11 used a global protection
  list. Since cpp11 no longer uses a global protection list and requires R
  >=3.5.0, it is no longer needed. As far as we can tell, no package was
  actively using this (#332).

* cpp11 now creates one protection list per compilation unit, rather than one
  global protection list shared across compilation units and across packages.
  This greatly reduces the complexity of managing the protection list state and
  should make it easier to make changes to the protection list structure in the
  future without breaking packages compiled with older versions of cpp11 (#330).

* Nested calls to `cpp11::unwind_protect()` are no longer supported or
  encouraged. Previously, this was something that could be done for performance
  improvements, but ultimately this feature has proven to cause more problems
  than it is worth and is very hard to use safely. For more information, see the
  new `vignette("FAQ")` section titled "Should I call \ 
  manually?" (#327).

* The features and bug fixes from cpp11 0.4.4 have been added back in.

# cpp11 0.4.5

* On 2023-07-20, cpp11 was temporarily rolled back to 0.4.3 manually by CRAN due
  to a bug in 0.4.4 which we could not immediately fix due to the cpp11
  maintainer being on vacation.

# cpp11 0.4.4

* Davis Vaughan is now the maintainer.

* `as_doubles()` and `as_integers()` now propagate missing values correctly
   (#265, #319).

* Fixed a performance issue related to nested `unwind_protect()` calls (#298).

* Minor performance improvements to the cpp11 protect code. (@kevinushey)

* `cpp_register()` gains an argument `extension=` governing the file extension of
  the `src/cpp11` file. By default it's `.cpp`, but `.cc` is now supported
  as well (#292, @MichaelChirico)

Log message:
(lang/R-cpp11) Updated 0.4.2 to 0.4.3

# cpp11 0.4.3

* Modernized the GitHub Actions workflows and updated some internal tests to
  better align with changes in those workflows and the latest version of R

* `cpp_source()` errors on non-existent file (#261).

* `cpp_register()` is quiet by default when R is non interactive (#289).

* updated test to adapt to changes in R 4.2.1 (#290).

Log message:
(lang/R-cpp11)  Updated 0.3.1 to 0.4.2

# cpp11 0.4.2

* Romain Fran├žois is now the maintainer.

# cpp11 0.4.1

* Fix crash related to unwind protect optimization (#244)

# cpp11 0.4.0

## New Features

* New  opt-in  message  formatting  with the  {fmt}  C++  library  for
  `cpp11::messages()` `cpp11::stop()` and `cpp11::warning()`.  Set the
  `CPP11_USE_FMT`    macro   to    use    this    feature   in    your
  package. (@sbearrows, #169, #208)

* New `as_double()` and `as_integer()` methods to coerce integers to
  doubles and doubles to integers to doubles (@sbearrows, #46)

* `cpp11::matrix` iterators can now be used either row-wise or
  column-wise (the default) depending on the user's choice (@alyst,

## Improvements and fixes

* Read-only matrix accessors are now marked const (#234)

* `writable::r_vector` default constructors now return a 0 length
  vector when converted to `SEXP` (#166)

* Read-only `r_vector` constructors now disallow implicit construction
  with named arguments (#237)

* Read-only `r_vector.attr()` methods now return const objects, so it
  is a compile time error to try to assign to them (#237)

* Fixed `+` and `+=` operators of `r_vector::[const_]iterator` to
  conform the *iterators* concept: `+=` updates the iterator, and `+`
  returns the updated copy, while keeping the original unchanged
  (@alyst, #231)

* Remove undefined behavior when constructing global `cpp11::sexp`s (#224)

* Removed redundant `.Call calls` in cpp11.cpp file (@sbearrows, #170)

* Error messages now output original file name rather than the
  temporary file name (@sbearrows, #194)

* `cpp_register()` now includes `attribute_visible` in the init
  function, so packages compiled with `C_VISIBILITY` will find the
  init function.

* Fixed bug when running `cpp_source()` on the same file more than
  once (@sbearrows, #202)

* Allow cpp11 decorators of the form `cpp11::linking_to` (@sbearrows,

* Removed internal instances of `cpp11::stop()` and replaced with C++
  exceptions (@sbearrows, #203)

* Names of named lists are now resized along with the list elements
  (@sbearrows, #206)

Log message:
(lang/R-cpp) Updated 0.2.4 to 0.2.7

# cpp11 0.2.7

* Fix a transient memory leak for functions that return values from
  `cpp11::unwind_protect()` and `cpp11::safe` (#154)

# cpp11 0.2.6

* `cpp_register()` now uses symbols exclusively in the `.Call()`
  interface. This allows it to be more robust in interactive use with
  the pkgload package.

# cpp11 0.2.5

* `cpp_source()` gains a `cxx_std` argument to control which C++
  standard is used.  This allows you to use code from `C++14` and
  later standards with cpp_source(). (#100)

* The cpp11 knitr engine now allows you to set the `cxx_std` chunk
  option to control the C++ standard used.

* `cpp_source()` now has much more informative error messages when
  compilation fails (#125, #139)

* `cpp_source()` now uses a unique name for the DLL, so works when run
  multiple times on the same source file on Windows (#143)

* `writable::list_of<T>` now supports modification of vectors as
  intended (#131).

* Errors when running
  `tools::package_native_routine_registration_skeleton()` are no
  longer swallowed (#134)

* `cpp_source()` can now accept a source file called `cpp11.cpp`

* `named_arg` now explicitly protect their values, avoiding protection
  issues when using large
  inputs. [tidyverse/readr#1145](https://github.com/tidyverse/readr/issues/1145)

* `r_string(std::string)` now uses `Rf_mkCharLenCE()` instead of
  `Rf_mkChar()`, which avoids the performance cost of checking the
  string length.

* Writable vector classes now properly set their lengths as intended
  when being copied to a read only class (#128).
