CRAN release: 2026-03-06

CRAN release: 2022-12-22

CRAN release: 2018-06-09

Added an internal data frame highr:::cmd_pandoc_latex (mainly for https://stackoverflow.com/q/40252885/559676).

CRAN release: 2016-05-09

hilight() can deal with multibyte characters that cannot represented in the system native encoding now (on Windows)
blank lines before/after code are preserved in the hilight() output now (thanks, Terry Therneau)

CRAN release: 2015-04-21

CRAN release: 2014-10-23

hi_andre() may fail to find highlight under OS X (thanks, Christopher Gandrud, #2)
:: and ::: are recognized as operators, and they will be syntax highlighted in the same way as other operators like +, -, *, and /, etc (thanks, Qiang Li, #3)

CRAN release: 2013-10-26

blank lines were not preserved in previous versions; now they can be correctly preserved
hilight() works when the code is only a comment; fixed the bug reported at http://stackoverflow.com/q/18548020/559676 which was actually due to the bug of utils::getParseData() in R 3.0.1
Linux Mint has a built-in version of highlight under /usr/local/bin/ which is not Andre Simon’s highlight, and this can hang highr (https://groups.google.com/forum/#!topic/knitr/nicYgzqhwX8)
the package vignettes were built with the knitr::docco_classic engine; see vignette(package = ‘highr’)

CRAN release: 2013-07-30

fixed a test that failed under R 2.15.x due to the keep.source argument in parse(), which was not available in R until R 3.0.0

CRAN release: 2013-07-29

added a new argument ‘fallback’ in hilight(); for R < 3.0.0, we can use hilight(…, fallback = TRUE), which is a rough syntax highlighting method based on regular expressions (hence less accurate and comphrehensive than the getParseData() approach); as a result, highr no longer has to depend on R 3.0.0, although it is recommended to use R 3.0.0

CRAN release: 2013-07-09

the first version of highr: a hilight() function based on utils::getParseData() to do syntax highlighting for R code; hi_andrew() as a wrapper for Andre Simon’s Highlight package
