New functions for progress bars, please see the new articles at https://cli.r-lib.org/articles/ for details.
New cli_abort(), cli_warn() and cli_inform() functions, to throw errors with cli pluralization and styling.
New format_inline() function to format a cli string without emitting it (#278).
New style_no_*() functions to locally undo styling. New col_none() and bg_none() functions to locally undo text color and background color.
It is now possible to undo text and background color in a theme, by setting them to NULL or "none".
cli_memo() was renamed to cli_bullets(), as it is by default formatted as a bullet list (#250).
New ansi_toupper(), ansi_tolower and ansi_chartr() functions, the ANSI styling aware variants of toupper(), tolower() and chartr() (#248).
New test_that_cli() helper function to write testthat tests for cli output.
New inline style: .cls to format class names, e.g. "{.var fit} must be an {.cls lm} object".
New cli_memo() function to create a list of items or tasks.
New cli::cli() function to create a single cli message from multiple cli calls (#170).
cli now highlights weird names, e.g. path names with leading or trailing space (#227).
Styling is fixed at several places. In particular, nested lists should be now formatted better (#221).
New spark_bar() and spark_line() funcions to draw small bar or line charts.
boxx() now correctly calculates the width of the box for non-ASCII characters.
New ansi_trimws() and ansi_strwrap() functions, they are similar to trimws() and strwrap() but work on ANSI strings.
New ansi_columns() function to format ANSI strings in multiple columns.
ansi_substr(), ansi_substring(), ansi_strsplit(), ansi_align() now always return ansi_string objects.
ansi_nchar(), ansi_align(), ansi_strtrim() and the new ansi_strwrap() as well handle wide Unicode correctly, according to their display width.
boxx() can now add headers and footers to boxes.
New style_hyperlink() function to add hyperlinks, on terminals that support them.
cli_format_method() now works properly in knitr, and other environments that catch message conditions (#159).
ANSI strings created by col_*, bg_* and style_* now also add the character class to the result. This fixes issues with code that expect character objects.
New functions to manipulate ANSI strings: ansi_aling(), ansi_has_any(), ansi_nchar(), ansi_regex(), ansi_strip(), ansi_strsplit(), ansi_substr(), ansi_substring().
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).
Progress bars now respect is_dynamic_tty() and do not output \r when this is false (@jimhester, #177)
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).
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.
Use Oxford comma when listing 3 or more items (@jonocarroll, #128).
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
is_dynamic_tty(), setting R_CLI_DYNAMIC="FALSE" now properly turns dynamic tty off (#70).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.
