v2.1.0

• New cli_vec() function to allow easier formatting of collapsed
  vectors. It is now also possible to use styling to set the collapsing
  parameters (#129).

• New pluralize() function to perform pluralization without generating
  cli output (#155).

• console_width() works better now in RStudio, and also in terminals.

• Styling of verbatim text work properly now (#147, @tzakharko).

• Messages (ie. message conditions) coming from cli now have the
  cliMessage class, so you can easily suppress them without suppressing
  other messages (#156).

• cli prints the output to stderr() now, if there is an output or
  message sink. This is to make interactive and non-interactive sessions
  consistent (#153).

• Pluralization works corrently now if the last alternative is the
  empty string (#158).

• cli now caches the result of the dark background detection in iTerm on
  macOS. Reload cli to delete the cache (#131).

• The is_dynamic_tty(), is_ansi_tty() and ansi_hide_cursor() and
  releted functions now default to the "auto" stream, which is
  automatically selected to be either stdout() or stderr().
  See the manual for details (#144).

• The default theme now quotes file names, paths, email addresses if they
  don't start or end with an alphanumeric character or a slash. This is
  to make it easier to spot names that start or end with a space (#167).

• make_spinner() clears the line properly now (@tzakharko, #164).

• Semantic cli functions now automatically replace Unicode non-breaking
  space characters (\u00a0) with regular space characters, right before
  output. They are still used to calculate the line breaks, but not
  outputted (#161).

v2.0.2

• The status bar now does not simplify multiple spaces by a single space.

• cli now does not crash if it fails to detect whether the RStudio theme
  is a dark theme (#138).

• cli now works better with wide Unicode characters, for example emojis.
  In particular, a status bar containing emojis is cleared properly (#133).

• The status bar now does not flicker when updated, in terminals (#135).

v2.0.1

• Symbols (symbol$*) are now correctly printed in RStudio on Windows (#124).

• The default theme for cli_code() output looks better now, especially
  in RStudio (#123).

• Remove spurious newline after a cli_process_start() was cleared
  manually, and also at the end of the function.

v2.0.0

Semantic command line interface tools

cli 2.0.0 has a new set of functions that help creating a CLI using a set
of higher level elements: headings, paragraphs, lists, alerts, code blocks,
etc. The formatting of all elements can be customized via themes.
See the "Building a semantic CLI" article on the package web site:
https://cli.r-lib.org

Bug fixes:

• Fix a bug in is_dynamic_tty(), setting R_CLI_DYNAMIC="FALSE" now
  properly turns dynamic tty off (#70).

v1.1.0

• cli has now functions to add ANSI styles to text. These use the crayon
  package internally, and provide a simpler interface. See the col_*,
  bg_*, style_* and also the make_ansi_style() and
  combine_ansi_styles() functions (#51).

• New is_dynamic_tty() function detects if \r should be used for a
  stream (#62).

• New is_ansi_tty() function detects if ANSI control sequences can be
  used for a stream.

• New ansi_hide_cursor(), ansi_show_cursor() and
  ansi_with_hidden_cursor() functions to hide and show the cursor in
  terminals.

• New make_spinner() function helps integrating spinners into your
  functions.

• Now symbol always uses ASCII symbols when the cli.unicode option is
  set to FALSE.

Bug fix release

Release Notes

• New cli_sitrep() function, situation report about UTF-8 and ANSI
  color support (#53).

• Fall back to ASCII only characters on non-Windows platforms without
  UTF-8 support, and also in LaTeX when running knitr (#34).
