cli 3.6.3

• 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).

cli 3.6.2

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

• ansi_collapse() gains a sep2 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).

cli 3.6.1

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

cli 3.6.0

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

• New hash_*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 the cli.progress_show_after
  option in ?cli-config for details (#542).

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

cli 3.5.0

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

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

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

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

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

• New hash_file_md5() function to calculate the MD5 hash of one or more
  files.

cli 3.4.1

• cli has better error messages now.

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

cli 3.4.0

• 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).

• Nested cli() calls work now (#497).

• Return values now work as they should within cli() 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 to url, and
  {.val pre-{x}-post} will format the whole value instead of x.
  (#422, #474).

• cli now replaces newline characters within {.class ... } inline styles
  with spaces. If the cli.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 to abort(). 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 variable VTE_VERSION
  is of the form \d{4}, i.e., 4 consecutive numbers (#441, @MichaelChirico)

• cli_dl() and its corresponding cli_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).

cli 3.3.0

• style_hyperlink() no longer breaks if the env varible VTE_VERSION
  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 the cli.num_colors option or the
  R_CLI_NUM_COLORS or the NO_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).

v3.2.0

Breaking change

• The cli_theme_dark option is know known as cli.theme_dark, to be
  consistent with all other cli option names (#380).

Other changes

• The preferred names of the S3 clases ansi_string, ansi_style, boxx,
  rule and tree now have cli_ prefix: cli_ansi_string, etc. This will
  help avoiding name conflicts with other packages eventually, but for now
  the old names are kept as well, for compatibility.

• cli_abort() has been updated to work nicely with rlang 1.0. The
  default call and backtrace soft-truncation are set to .envir
  (which itself is set to the immediate caller of cli_abort() by
  default).

  Line formatting now happens lazily at display time via
  rlang::cnd_message() (which is called by the conditionMessage()
  method for rlang errors).

• New hash_sha256() function to calculate SHA-256 hashes. New
  hash_raw_*(), hash_obj_*() and hash_file_*() functions to calculate
  various hashes of raw vectors, R objects and files.

• You can use the new cli.default_num_colors option to set the default
  number of ANSI colors, only if ANSI support is otherwise detected.
  See the details in the manual of num_ansi_colors().

• You can set the new ESS_BACKGROUND_MODE environment variable to
  dark to indicate dark mode.

• cli now handles quotes and comment characters better in the semantion
  cli_*() functions that perform glue string interpolation (#370).

v3.1.1

• style_hyperlink() gains a params= argument (#384).
