# CHANGES IN xfun VERSION 0.16 - Added a new function `base64_decode()` to decode data from the base64 encoding (thanks, @wush978, #31). # CHANGES IN xfun VERSION 0.15 ## NEW FEATURES - Added a new function `tree()`, which is based on `str()` in base R, but changes the output of `str()` into a tree diagram to make it easier to understand nested data structures. - Added a new function `base64_encode()` to encode data into the base64 encoding (thanks, @wush978, #27). - Added a new function `base64_uri()` to generate the Data URI (or Data URL) for a file. ## BUG FIXES - Fenced code blocks commented out in `<!-- -->` are not longer recognized as code blocks but prose (thanks, @jarauh, #25). # CHANGES IN xfun VERSION 0.14 ## NEW FEATURES - The `cache_rds()` function can invalidate the cache automatically when the code passed to its `expr` argument has changed. Two new arguments, `hash` and `clean` were added to this function to make it more useful and powerful. See the help page `?xfun::cache_rds()` for more information. # CHANGES IN xfun VERSION 0.13 ## NEW FEATURES - Added a new function `cache_rds()` to cache an R expression to a `*.rds` file. - Added a new function `Rscript_call()` to call a function (with arguments) in a new R session via the command `Rscript`. - The `recheck` argument of `rev_check()` can take a vector of package names, and only these packages will be checked. See `?xfun::rev_check` for more details. # CHANGES IN xfun VERSION 0.12 ## NEW FEATURES - Added a new function `split_lines()`. # CHANGES IN xfun VERSION 0.11 ## BUG FIXES - `read_utf8()` will read the file with `options(encoding = 'native.enc')` and ignore user's setting such as `options(encoding = 'UTF-8')` (#21). # CHANGES IN xfun VERSION 0.10 ## NEW FEATURES - Added the function `as_strict_list()` to convert an existing object to a strict list without wrapping it in another list if the object already is of type list (in contrast to how `strict_list()` behaves) (thanks, @salim-b, #20). # CHANGES IN xfun VERSION 0.9 ## NEW FEATURES - Added a function `rename_seq()` to rename files to add an incremental numeric prefix to the filenames, e.g., rename `a.txt`, `b.txt`, `c.txt` to `1-a.txt`, `2-b.txt`, `3-c.txt`. # CHANGES IN xfun VERSION 0.8 ## MINOR CHANGES - `xfun::write_utf8(NULL)` is equivalent to `xfun::write_utf8(character(0))` now (thanks, @schloerke, yihui/knitr#1714). # CHANGES IN xfun VERSION 0.7 ## MINOR CHANGES - `loadable()` is quiet with R 3.6.0 (https://stat.ethz.ch/pipermail/r-devel/2019-May/077774.html). # CHANGES IN xfun VERSION 0.6 ## NEW FEATURES - Added the `...` argument to `same_path()` to pass additional arguments to `normalize_path()`. ## BUG FIXES - The `warn` argument in `prose_index()` failed to suppress warnings. # CHANGES IN xfun VERSION 0.5 ## NEW FEATURES - Added functions `upload_ftp()` and `upload_win_builder()` to upload files to FTP servers. - Added a function `stringsAsStrings()` (see its help page for details). - Added an argument `warn` to `prose_index()` to suppress the warning when code fences are not balanced. ## BUG FIXES - Fixed the bug that `prose_index()` recognizes double backticks as code fences (thanks, @shrektan, #14 #15). # CHANGES IN xfun VERSION 0.4 ## NEW FEATURES - Added functions `embed_file()`, `embed_dir()`, and `embed_files()` to embed files in an HTML output file (e.g., from R Markdown), so that the files can be directly downloaded from the web browser. One use case is to call one of these functions in an R code chunk of an Rmd document to embed the Rmd source document or data files in the HTML output, so readers can download them. - Added a new argument `message` to `pkg_attach()`, so you can suppress package startup messages via `xfun::pkg_attach(..., message = FALSE)` or set the global option `options(xfun.pkg_attach.message = FALSE)` (thanks, @wch, yihui/knitr#1583). ## MINOR CHANGES - The argument `rw_error` was moved from `gsub_dir()` to `gsub_file()` (`gsub_dir(rw_error = ...)` will still work). - `is_ascii()` now returns `NA` for `NA_character_` (thanks, @shrektan, #8 #9). # CHANGES IN xfun VERSION 0.3 ## NEW FEATURES - Added a new functions `download_file()` to try various methods to download a file. - Added a new function `is_ascii()` to test if a character vector only consists of ASCII characters. - Added a new function `numbers_to_words()` to convert numbers to English words (thanks, @daijiang, #3). # CHANGES IN xfun VERSION 0.2 ## NEW FEATURES - Added a `new_session` argument to `loadable()`. - Added new functions `gsub_file()`, `gsub_files()`, `gsub_dir()`, and `gsub_ext()` to replace strings in files. - Added new functions `Rscript` and `Rcmd` as wrappers of `system2('Rscript')` and `system2('R', 'CMD')`, respectively. - Added a new function `install_dir()` to install a source package from a directory. - Added a new function `file_string()` to read a text file (encoded in UTF-8) and return its content a single character string (lines concatenated by `\n`). - Added a new function `raw_string()` to print a character vector in its "raw" form using `cat(..., sep = '\n')` instead of `print()`, because the latter may introduce `[1]`, "extra" double quotes, and escape sequences, which are not very human-readable. - Added a new function `session_info()` as an alternative to `sessionInfo()`. - Added a new function `rev_check()` to run `R CMD check` on the reverse dependencies of a package, and a corresponding helper function `compare_Rcheck()` for showing the differences in logs with the CRAN version and the current version of the package, respectively. - Added new functions for dealing with Markdown text: `prose_index()` returns the line indices of text that is prose (not code blocks), and `protect_math()` protects math expressions in Markdown in backticks. - Added an `error` argument to `read_utf8()` to signal an error if the file is not encoded in UTF-8. # CHANGES IN xfun VERSION 0.1 ## NEW FEATURES - `attr()` as an abbreviation of `base::attr(exact = TRUE)`. - `file_ext()`, `sans_ext()`, and `with_ext()` to manipulate extensions in filenames. - `in_dir()` to evaluate an R expression in a directory. - `isFALSE()` as an abbreviation of `identical(x, FALSE)`. - `is_windows()`, `is_macos()`, `is_linux()`, and `is_unix()` to test operating systems. - `native_encode()` to try to encode a character vector in the native encoding. - `normalize_path()` as an abbreviation of `normalizePath(winslash = '/', mustWork = FALSE)`. - `optipng()` to run the command `optipng` to optimize all PNG files under a directory. - `parse_only()` parses R code without keeping the source references. - `pkg_attach()` and `pkg_load()` to attach and load a vector of packages, respectively (and optionally, install the missing packages). - `read_utf8()` and `write_utf8()` to read and write UTF-8 files, respectively. - `same_path()` to test if two paths are the same. - `strict_list()` is a version of `list()` that disables partial matching of the `$` operator. - `tojson()` is a simple JSON serializer. - `try_silent()` is an abbreviation of `try(silent = TRUE)`.
