(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.
