split.nl option to set_knit_hooks to mitigate white space issues when using blackfriday for the markdown->html conversion (@krlmlr).ctl parameter to most functions. Some functions such as strip_ctl had existing parameters that did the same thing (e.g. strip, or which), and those have been deprecated in favor of ctl. While technically this is a change in the API, it is backwards compatible (addresses #56 among and other things).*_sgr version of most *_ctl functions.nzchar_ctl gains the ctl parameter.strsplit_ctl can now work with ctl parameters containing escape sequences provided those sequences are excluded from by the ctl parameter.sgr_to_html so that it can handle vector elements with un-terminated SGR sequences (@krlmlr).strwrap_ctl when indent/exdent/prefix/initial widths vary from first to second line.strwrap2_*(..., strip.spaces=FALSE), including a bug when wrap.always=TRUE and a line started in a word-whitespace boundary.term.cap parameter to unhandled_ctl.fansi::set_knit_hooks makes it easy to automatically convert ANSI CSI SGR sequences to HTML in Rmarkdown documents. We also add a vignette that demonstrates how to do this.strsplit.substr behavior starting with R-3.6.strsplit_ctl.Initial release.
