xfun 0.40

• number_to_words() supports decimal numbers now (thanks, @harshvardhaniimi, #80).

• is_ascii() is more robust now (thanks, @bastistician, #81).

xfun 0.39

• Fixed a bug that protect_math() fails to protect the starting $$ that has leading white spaces.

• Added a function strip_html() to remove HTML tags and comments from text.

• The function alnum_id() will remove HTML tags and comments from text (using strip_html()) before converting it to an ID string.

• Added a function env_option() to retrieve an option value from options(). If the option does not exist there, check the environment variables. This provides a way for users to set an option via either options() or an environment variable.

xfun 0.38

• Added an object download_cache, which is a list of methods to download a URL, cache the result, retrieve the result from the cache, and clear the cache.

• Added an argument default to url_filename() to provide a default filename when it cannot be determined from the URL.

• Added a function yaml_load() to read YAML data when the yaml package is not available. It only supports a limited number of data types and is supposed to be used as a fallback method. See the help page ?xfun::yaml_load for details.

• Added a function yaml_body() to split a document into YAML metadata and the body.

• is_arm64() also supports Linux now (thanks, @eitsupi, #74).

• is_blank() returns a logical vector of the same length as the input vector now, indicating if each element of the input is blank. Previously it returns a logical scalar indicating whether all elements are blank. If you want the old behavior, you can use all(is_blank()).

xfun 0.37

• Added a function is_arm64() to test the CPU type (thanks, @AlbanSagouis, #72).

• Started deprecating xfun::isFALSE() in favor of base::isFALSE() for R >= 3.5.0 (thanks, @mmaechler, #66); isFALSE() will eventually be removed from xfun when we do not need to support R < 3.5.0.

xfun 0.36

• Added a new argument resolve_symlink to normalize_path() to get the absolute paths of symlinks without resolving them (with resolve_symlink = FALSE).

xfun 0.35

• Added a new argument token to protect_math() to optionally include a token around math expressions.

• base64_uri() relies less on the mime package now. For some common file extensions (e.g., .jpg/.png), this function knows their MIME types.

• stringsAsStrings() has been removed from this package.

xfun 0.34

• Added a new function alnum_id() to generate ID strings from a character vector.

• The function stringsAsStrings() has been deprecated.

xfun 0.33

• Reverted the change for #68: the characters -+!_# are no longer accepted by default in filename extensions, since they are relatively rare and caused a breakage in rstudio/bookdown#1369. If you wish to allow for these characters, you may use the new extra argument in file_ext() and related functions, e.g., xfun::file_ext(x, extra = '-+!_#').

• The function stringsAsStrings() will be deprecated in a future release of xfun, because the global option stringsAsFactors = FALSE has become the default in base R since 4.0.0.

xfun 0.32

• Added a function shrink_images() to shrink images to a maximum width using the magick package (thanks, @apreshill, rstudio/blogdown#614).

• Added a function tinify_dir() as a wrapper of tinify() to compress images under a directory.

• file_ext() supports more file extensions now, such as .c++, .FB2K-COMPONENT, and so on (thanks, @tentacles-from-outer-space, #68).

• Fixed the issue that xfun::base_pkgs() could hang R (thanks, @mmaechler, #66).

• The ... argument in dir_create() was not passed to dir.create().

xfun 0.31

• github_releases(use_jsonlite = FALSE) supports R versions below 4.1.0 now.

• session_info() silently drops empty package names now (thanks, @phargarten2, #65).
