(devel/R-xfun) Updated 0.2.0 to 0.23
# CHANGES IN xfun VERSION 0.23 ## NEW FEATURES - Added a `tinify()` function to compress PNG/JPEG images via [the Tinify API](https://tinypng.com/developers). - Added a `news2md()` function to convert package news to the Markdown format. This is mainly for converting the plain-text `NEWS` file and the `NEWS.Rd` file to `NEWS.md`. - Added a `format_bytes()` function to format numbers of bytes using a specified unit, e.g., `1024` can be formatted as `1 Kb`. - When using `pkg_load2()` in an **renv** project, it will use `renv::install()` to install missing packages by default to take advantage of **renv**'s caching feature (thanks, @chunyunma @cderv, #52). - `upload_win_builder()` no longer requires the system command `curl` to be available; if `curl` is not available, the R package **curl** will be used instead, which means this R package must be installed. In addition to uploading to the `ftp` server of win-builder, it's also possible to upload to <https://win-builder.r-project.org/upload.aspx>: call `upload_win_builder(..., server = 'https')`. This change was made so that it would be possible to continue to upload to win-builder in case it should stop supporting `ftp` (CRAN has discouraged package authors from using `ftp://`). ## BUG FIXES - Backticks are added to math environments by mistake when `\begin{}` and `\end{}` do not match (thanks, @oliviergimenez, #51). ## MINOR CHANGES - The argument `src` was renamed to `pkg` in `install_dir()`. - The argument `file` of `upload_win_builder()` defaults to `pkg_build()` now, i.e., by default, it will build a source package and upload it, so you do not need to build the package separately. # CHANGES IN xfun VERSION 0.22 ## NEW FEATURES - `relative_path()` is vectorized now. - Added a new function `retry()` to retry calling a function for a number of times in case of errors. - Added a new function `sort_file()`, which is a shorthand for `process_file(fun = sort)` to sort the lines in a text file. ## MAJOR CHANGES - The argument `FUN` was renamed to `fun` in `process_file()`. ## MINOR CHANGES - Inside `download_file()`, the `timeout` option in `options()` is set to 3600 seconds when it takes the default value of 60 seconds, which may not be enough for downloading large files (thanks, @matthewgson, rstudio/tinytex#286). # CHANGES IN xfun VERSION 0.21 ## NEW FEATURES - Added a new function `pkg_available()` to test if a package with a minimal version is available (thanks, @cderv, #45). - Added a new function `set_envvar()` to set environment variables and return their old values, so they could be restored later. - Added a new function `exit_call()` to call a function when a parent function exits. - Exported the internal function `read_bin()`. - Added an argument `verbose` to `bg_process()`. - `Rscript_call()` gains an `options` argument to pass command-line options to `Rscript` (thanks, @cderv, #48).
