(textproc/R-stringr) Updated 1.4.0 to 1.5.0
# stringr 1.5.0 ## Breaking changes * stringr functions now consistently implement the tidyverse recycling rules (#372). There are two main changes: * Only vectors of length 1 are recycled. Previously, (e.g.) `str_detect(letters, c("x", "y"))` worked, but it now errors. * `str_c()` ignores `NULLs`, rather than treating them as length 0 vectors. Additionally, many more arguments now throw errors, rather than warnings, if supplied the wrong type of input. * `regex()` and friends now generate class names with `stringr_` prefix (#384). * `str_detect()`, `str_starts()`, `str_ends()` and `str_subset()` now error when used with either an empty string (`""`) or a `boundary()`. These operations didn't really make sense (`str_detect(x, "")` returned `TRUE` for all non-empty strings) and made it easy to make mistakes when programming. ## New features * Many tweaks to the documentation to make it more useful and consistent. * New `vignette("from-base")` by @sastoudt provides a comprehensive comparison between base R functions and their stringr equivalents. It's designed to help you move to stringr if you're already familiar with base R string functions (#266). * New `str_escape()` escapes regular expression metacharacters, providing an alternative to `fixed()` if you want to compose a pattern from user supplied strings (#408). * New `str_equal()` compares two character vectors using unicode rules, optionally ignoring case (#381). * `str_extract()` can now optionally extract a capturing group instead of the complete match (#420). * New `str_flatten_comma()` is a special case of `str_flatten()` designed for comma separated flattening and can correctly apply the Oxford commas when there are only two elements (#444). * New `str_split_1()` is tailored for the special case of splitting up a single string (#409). * New `str_split_i()` extract a single piece from a string (#278, @bfgray3). * New `str_like()` allows the use of SQL wildcards (#280, @rjpat). * New `str_rank()` to complete the set of order/rank/sort functions (#353). * New `str_sub_all()` to extract multiple substrings from each string. * New `str_unique()` is a wrapper around `stri_unique()` and returns unique string values in a character vector (#249, @seasmith). * `str_view()` uses ANSI colouring rather than an HTML widget (#370). This works in more places and requires fewer dependencies. It includes a number of other small improvements: * It no longer requires a pattern so you can use it to display strings with special characters. * It highlights unusual whitespace characters. * It's vectorised over both string` and `pattern` (#407). * It defaults to displaying all matches, making `str_view_all()` redundant (and hence deprecated) (#455). * New `str_width()` returns the display width of a string (#380). * stringr is now licensed as MIT (#351). ## Minor improvements and bug fixes * Better error message if you supply a non-string pattern (#378). * A new data source for `sentences` has fixed many small errors. * `str_extract()` and `str_exctract_all()` now work correctly when `pattern` is a `boundary()`. * `str_flatten()` gains a `last` argument that optionally override the final separator (#377). It gains a `na.rm` argument to remove missing values (since it's a summary function) (#439). * `str_pad()` gains `use_width` argument to control whether to use the total code point width or the number of code points as "width" of a string (#190). * `str_replace()` and `str_replace_all()` can use standard tidyverse formula shorthand for `replacement` function (#331). * `str_starts()` and `str_ends()` now correctly respect regex operator precedence (@carlganz). * `str_wrap()` breaks only at whitespace by default; set `whitespace_only = FALSE` to return to the previous behaviour (#335, @rjpat). * `word()` now returns all the sentence when using a negative `start` parameter that is greater or equal than the number of words.
