xfun 0.50

• The function isFALSE() has been removed from this package. The deprecation notice was given two years ago: https://yihui.org/en/2023/02/xfun-isfalse/

• Added a new function tabset() to represent a list with a tabset. The representation is similar to str(), but uses a visual form.

• Factored out the function taml_load() and exported it (TAML is a tiny subset of YAML). Also added a new function taml_save() to convert simple lists to YAML.

• The print argument of record() can accept non-function values now, in which case print() (or show() for S4 objects) will be used as the print function.

• The record() results can also be formatted to Markdown via format(record(), to = 'markdown').

• Moved knitr::combine_words() into this package as xfun::join_words(). The former has become a simple wrapper of the latter.

• Similarly, moved knitr::write_bib() into this package as xfun::pkg_bib().

• Moved the internal function str_wrap() from knitr and exported it as xfun::str_wrap().

• Exported the internal find_globals() and find_locals() functions.

• md_table() escapes | in the table to \| instead of | now.

• yaml_load(use_yaml = FALSE) allows for indenting sub-fields by any number of spaces now (thanks, @J-Moravec, #95). Previously, one level of indentation must use exactly 2 spaces.

• divide_chunk() no longer requires every line of chunk options to be commented out when the engine uses a pair of comment delimiters (such as /* and */ for CSS) instead of a single comment character. It suffices to use the opening delimiter at the beginning and closing delimiter at the end, e.g.,

  ```{css}
  /*| echo=FALSE,
      label='foo' */
  ```

  Previously, every line must be commented out like:

  ```{css}
  /*| echo=FALSE, */
  /*| label='foo' */
  ```

• The package has a website now: https://git.yihui.org/xfun/
