# 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 () 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.
