crayon (development version)

crayon 1.5.3

  • The semantics of the cli.default_num_colors options is now different. It is now used as the default number of colors if the number of colors is not already set by the cli.num_colors option, the R_CLI_NUM_COLORS environment variable, the crayon.enabled and crayon.colors options, the NO_COLOR environment variable, the knitr.in.progress option, or a sink() call for the stream. This matches the behavior of the cli package.

crayon 1.5.2

  • crayon functions now mark their output with the right encoding, if their input was marked (#136, #138).

1.5.1

  • crayon now does not fail to install from source if the utils package is not loaded (#133).

1.5.0

  • 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(). (From cli.)

  • crayon now install cleanly on R 3.4.x and R 3.5.x on Windows (#131).

1.4.2

  • Better ANSI support detection if there is an active sink().

  • Support ANSI markup in RStudio jobs.

1.4.1

  • ANSI color support detection works correctly now in older RStudio (#112).

  • ANSI color support detection works correctly now on older R versions (#109).

1.4.0

  • Overhauled and much improved detection of ANSI color support and number of ANSI colors.

  • NO_COLOR environment variable disables color (#64)

  • Now colors are turned on if ANSICON (https://github.com/adoxa/ansicon) is active.

  • New hyperlink() function to add hyperlinks to terminal output. The new has_hyperlink() function tests if the current stdout() supports this.

  • reset style now restores previous style for text following it (@brodieG, #35).

  • Warnings are no longer generated when the INSIDE_EMACS environment variable is set but does not include a version number.

1.3.4

  • Style functions convert arguments to character now

  • Autodetect RStudio ANSI support

  • col_align() gains type argument, default "width" (#54).

1.3.2

  • Removed dependency to memoise (@brodieG, #25)

  • Fixed a test case that changed the crayon.enabled setting, potentially (@brodieG)

  • Added crayon.colors option, to specify the number of colors explicitly

  • TERM=xterm and tput colors=8 will use 256 colors, as 256 colors are usually supported in this case (#17)

  • Support colors in ConEmu and cmder, on Windows

  • Fix color detection in Emacs tramp

  • col_strsplit and col_substr corner cases:

    • handle empty chunks at beginning or end of strings like base::strsplit (@brodieG, #26)

    • explicitly deal with 'split' values that are not length 1 as that is not currently supported

    • handle zero length x argument in col_substr, and add more explicit error messages for corner cases

  • Some performance improvements to col_substr (@brodieG)

  • Change rgb to ANSI code mapping, based on the "paint" ruby gem (@richfitz, #33, #34)

1.3.1

  • Fixed some R CMD check problems.

1.3.0

  • Colors are turned on by default in Emacs ESS 23.x and above.

  • Functions to turn on and off a style: start, finish.

  • Really fix tput corner cases (@jimhester, #21)

1.2.1

  • Fix detecting number of colors when tput exists, but fails with an error and/or does not return anything useful. (@jimhester, #18, #19)

1.2.0

  • Fix detection of number of colors, it was cached from installation time (#17).

  • Color aware string operations. They are slow and experimental currently.

1.1.0

  • show_ansi_colors() prints all supported colors on the screen.

  • 256 colors, on terminals that support it.

  • Disable colors on Windows, they are not supported in the default setup.

1.0.0

  • First released version.
