./devel/R-withr, Run code with temporarily modified global state

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


Branch: CURRENT, Version: 3.0.1, Package name: R-withr-3.0.1, Maintainer: pkgsrc-users

A set of functions to run code 'with' safely and temporarily modified
global state. Many of these functions were originally a part of the
'devtools' package, this provides a simple package with limited
dependencies to provide access to these functions.


Required to run:
[math/R]

Required to build:

(devel/R-withr) Update 2.5.0 to 3.0.0

# withr 3.0.0

## Performance of withr

* `defer()` is now a thin wrapper around `base::on.exit()`. This is
  possible thanks to two contributions that we made to R 3.5:

  - We added an argument for FIFO cleanup: `on.exit(after = FALSE)`.
  - Calling `sys.on.exit()` elsewhere than top-level didn't work. This
    is needed for manual invokation with `deferred_run()`.

  Following this change, `defer()` is now much faster (although still
  slower than `on.exit()` which is a primitive function and about as
  fast as it gets). This also increases the compatibility of `defer()`
  with `on.exit()` (all handlers are now run in the expected order
  even if they are registered with `on.exit()`) and standalone
  versions of `defer()`.

## Breaking change

* When `source()` is used with a local environment, as opposed to
  `globalenv()` (the default), you now need to set
  `options(withr.hook_source = TRUE)` to get proper withr support
  (running `defer()` or `local_` functions at top-level of a script).
  THis support is disabled by default in local environments to avoid a
  performance penalty in normal usage of withr features.

## Other features and bugfixes

* `deferred_run()` now reports the number of executed expressions with
  a message.

* `deferred_run()` can now be run at any point in a knitr file (#235).

,* `local_tempfile()` now writes `lines` in UTF-8 (#210) and always uses
  `\n` for newlines (#216).

* `local_pdf()` and friends now correctly restore to the previously
  active device (#138).

* `local_()` now works even if withr isn't attached (#207).

* `local_par()` and `with_par()` now work if you don't set any parameters
  (#238).

* `with_language()` now properly resets the translation cache (#213).

* Fixes for Debian packaging.

# withr 2.5.2

* Fixes for CRAN checks.

# withr 2.5.1

* Fixes for CRAN checks.

(devel/R-withr) Updated  2.4.3 to 2.5.0

# withr 2.5.0

* `defer()` and all `local_*()` functions now work when run inside of
  a `.Rmd`. The deferred expressions are executed when knitr exits.

* `defer()` and `local_` functions now work within `source()`.
  The deferred expressions are executed when `source()` exits.

* `with_()` and `local_()` gain a `get` argument. Supply a getter
  function to create `with` and `local` functions that are robust to
  early exits.

  When supplied, this restoration pattern is used:

  ```
  old <- get()
  on.exit(set(old))
  set(new)
  action()
  ```

  Instead of:

  ```
  old <- set(new)
  on.exit(set(old))
  action()
  ```

  This ensures proper restoration of the old state when an early exit
  occurs during `set()` (for instance when a deprecation warning is
  caught, see #191).

* These `with_` and `local_` functions are now robust to early exits (see next \ 
bullet):

  - `_locale()`
  - `_envvar()`
  - `_libpaths()`
  - `_options()`
  - `_par()`
  - `_path()`
  - `_seed()`

* `with_namespace()` and `local_namespace()` now pass `warn.conflicts`
  to `attach()` (@kyleam, #185).

* `local_rng_version()` and `local_seed()` no longer warn when
  restoring `sample.kind` to `"Rounding"` (#167).

* `with_seed()` now preserves the current values of `RNGkind()` (#167).

* `with_collate()` is no longer affected by the `LC_COLLATE`
  environment variable set to "C" (#179).

* Local evaluations in the `globalenv()` (as opposed to top-level
  ones) are now unwound in the same way as regular environments.

* `local_tempfile()` gains a lines argument so, if desired, you can pre-fill
  the temporary file with some data.

R-withr: update to 2.4.3 (and un-break bulk builds)

# withr 2.4.3

* Lionel Henry is the new maintainer.

* Handlers registered with the global environment (as happens when `local_()`
  is run at the top-level, outside a function) are now automatically run
  when the R session ends (#173).

* New `with_language()` and `local_language()` to temporarily control the
  language used for translations (#180).

* `with_seed()` now caches the check for R version, so is now faster (#170)

* `with_makevars()` and `local_makevars()` now eagerly evaluate the `path` \ 
argument (#169)

Log message:
(devel/R-withr) Update 2.4.1 to 2.4.2

# withr 2.4.2
- `local_options()` now lets you set an option to `NULL` as intended (#156)

- `local_tempfile()` argument `envir` is deprecated, in favor of
  `.local_envir`.  All withr functions except `local_tempfile()` used
  `.local_envir` to specify environments, so this makes this function
  consistent with the rest. (#157)

- `with_environment()` now passing `pos` and `warn.conflicts` to
  `attach()`, as intended (#161).

- `with_seed()` now also sets the RNG via new arguments `.rng_kind`,
  `.rng_normal_kind` and `.rng_sample_kind` (#162, @AshesITR).

- `with_timezone()` now works after recent changes to `Sys.timezone()`
  in R-devel (#165)

(devel/R-withr) Updated 2.3.0 to 2.4.1  (make test fails at UTF-8 coding)

# withr 2.4.1

- Tests which require `capabilities("cairo")` are now skipped.

# withr 2.4.0

- withr is now licensed as MIT (#154).

- Tests For `with_cairo_pdf()` and `with_cairo_ps()` have been
  removed, as they fail if Cairo is not available, such as with M1
  macOS systems (#158)

- `local_seed()` is now exported (#153)
