• code_highlight() supports long strings and symbols
  (#727@moodymudskipper).

Contributors

• Pluralization now handles edge cases (NA,NaN,Inf and-Inf)
  better (@rundel,#716).

• The URI generated for.file,.run,.help and.vignette hyperlinks
  can now be configured via options and env vars (@jennybc,#739,#744).

• cli_progress_bar() now acceptstotal = Inf or -Inf which mimics the
  behavior of whentotal is NA (@LouisMPenrod,#630).

• num_ansi_colors() now does not warn in Emacs if theINSIDE_EMACS
  environment variable is not a proper version number (@rundel,#689).

• ansi_collapse() and inline collapsing now useslast as the separator
  (without the serial comma) for two-element vectors ifsep2 is not
  given (@rundel,#681).

• ansi_collapse() is now correct for length-1 vectors with style "head"
  if width is specified (@rundel,#590).

• Newhash_xxhash() etc. functions to calculate the xxHash of strings,
  raw vectors, objects, files.

Contributors

• cli now builds on ARM Windows.

• "Solarized Dark" is now the default syntax highlighting theme in
  terminals.

• The{.obj_type_friendly} inline style now only shows the first class
  name (#669@olivroy).

• Syntax highlighting now does not fail in RStudio if the rstudioapi
  package is not installed (#697).

Contributors

• ansi_collapse(x, trunc = 1, style = "head") now indeed shows one
  element iflength(x) == 2, as documented (@salim-b,#572).

• ansi_collapse() gains asep2 argument to specify a seperate separator
  for length-two inputs. It defaults to" and " which, in conjunction with
  the other defaults, produces a collapsed string that fully adheres to the
  serial comma rules.
  (@salim-b,#569)

• ansi_string() is now an exported function (@multimeric,#573).

Contributors

• ANSI hyperlinks are now turned off on the RStudio render plane (#581).

• The progressr progress handler now reports progress correctly
  (@HenrikBengtsson,#558).

• Newhash_*sha1() functions to calculate the SHA-1 hash of strings,
  objects, files.

• cli now shows progress bars after one second by default, if they
  are less than half way at the point. (Or after two seconds,
  unconditionally, as before.) See the thecli.progress_show_after
  option in?cli-config for details (#542).

• format_inline() now has a new argumentkeep_whitespace, and it keeps
  whitespace, including newline and form feed characters by default.

Contributors

• Newkeypress() function to read a single key press from a terminal.

• New functionpretty_print_code() to print function objects with syntax
  highlighting at the R console.

• col_* andbg_* functions how handle zero-length input correctly (#532).

• New functionansi_collapse() to collapse character vectors into a single
  string.

• ansi_strtrim() now handles some edge cases better, whenellipsis has
  length zero, and when it is wider thanwidth.

• Newhash_file_md5() function to calculate the MD5 hash of one or more
  files.

• cli has better error messages now.

• Newformat_inline() argument:collapse, to collapse multi-line output,
  potentially because of\f characters.

• New experimental styles to create ANSI hyperlinks in RStudio and
  terminals that support them. See?cli::links for details (#513).

• Expressions that start and end with a{} substitution are now styled
  correctly. E.g.{.code {var1} + {var2}} (#517).

• New{.obj_type_friendly} inline style to format the type of an R object
  in a user friendly way (#463).

• Improved vector collapsing behavior. cli now shows both the beginning
  and end of the collapsed vector, by default (#419).

• Nestedcli() calls work now (#497).

• Return values now work as they should withincli() calls (#496).

• Style attributes with underscores have new names with dashes instead:
  vec_sep,vec_last,vec_trunc,string-quote. The old names still
  work, but the new ones take precedence (#483).

• cli now does not crash at the end of the R session on Arm Windows
  (#494;@kevinushey)

• Vectors are truncated at 20 elements now by default, instead of 100 (#430).

• 20 new spinners from the awesome
  cli-spinners package,
  and from@HenrikBengtsson in#469.
  Run this to demo them, some need UTF-8 and emoji support:

  new<- c("dots13","dots8Bit","sand","material","weather","christmas","grenade","point","layer","betaWave","fingerDance","fistBump","soccerHeader","mindblown","speaker","orangePulse","bluePulse","orangeBluePulse","timeTravel","aesthetic","growVeriticalDotsLR","growVeriticalDotsRL","growVeriticalDotsLL","growVeriticalDotsRR")demo_spinners(new)

• cli exit handlers are now compatible again with the withr package (#437).

• cli functions now keep trailing\f characters as newlines.
  They also keep multiple consecutive\f as multiple newlinees (#491).

• {} substitutions within inline styles are now formatted correctly.
  E.g.{.code download({url})} will not add backticks tourl, and
  {.val pre-{x}-post} will format the whole value instead ofx.
  (#422,#474).

• cli now replaces newline characters within{.class ... } inline styles
  with spaces. If thecli.warn_inline_newlines option is set to TRUE, then
  it also throws a warning. (#417).

• code_highlight now falls back to the default theme (instead of no theme)
  for unknown RStudio themes (#482,@rossellhayes).

• cli_abort() now supplies.frame toabort(). This fixes an
  issue with the.internal = TRUE argument (r-lib/rlang#1386).

• cli now does a better job at detecting the RStudio build pane, job pane
  and render pane, and their capabilities w.r.t. ANSI colors and hyperlinks.
  Note that this requires a daily build of RStudio (#465).

• New functions for ANSI strings:ansi_grep(),ansi_grepl(),
  ansi_nzchar(). They work like the corresponding base R functions, but
  handle ANSI markup.

• style_hyperlink() (really) no longer breaks if the env variableVTE_VERSION
  is of the form\d{4}, i.e., 4 consecutive numbers (#441,@MichaelChirico)

• cli_dl() and its correspondingcli_li() can now style the labels.

• The behavior cli's inline styling expressions is now more predictable.
  cli does not try to evaluate a styled string as an R expression any more.
  E.g. the meaning of"{.emph +1}" is now always the "+1", with style
  .emph, even if an.emph variable is available and the.emph + 1
  expression can be evaluated.

• Functions that apply bright background colors (e.g.bg_br_yellow()) now
  close themselves. They no longer format text after the end of the function
  (#484,@rossellhayes).

  is of the form\d{4}, i.e., 4 consecutive numbers (#441,@MichaelChirico)

• ansi_*() functions support ANSI hyperlinks again (#444).

• Turning off ANSI colors via thecli.num_colors option or the
  R_CLI_NUM_COLORS or theNO_COLOR environment variable now also turns off
  ANSI hyperlinks (#447).

• symbol now only has two variants: UTF-8 and ASCII. There are no special
  variants for RStudio and Windows RGui any more (#424).
