What is downlit?

downlit's HTML contract was set in 0.4.0; every release since tracks R itself.

downlit does syntax highlighting and automatic linking of R code to documentation, and is the engine behind pkgdown's code blocks. Version 0.4.0 restructured its output into the class taxonomy themes style against, and 0.4.1 completed it with base pipe support and per-line spans. The three releases since are compatibility fixes for R and R-devel.

What is highr?

highr is finished software: one-line releases every year or two

highr does syntax highlighting for knitr output, and every release in this window is a single line of change. The most recent wraps hilight() output in xfun::raw_string() for nicer printing; before that, a rename of two LaTeX command macros and two bumps to the minimum R version. There is no feature work here at all.

0.0

downlit's HTML contract was set in 0.4.0; every release since tracks R itself.

◆ Current state

downlit does syntax highlighting and automatic linking of R code to documentation, and is the engine behind pkgdown's code blocks. Version 0.4.0 restructured its output into the class taxonomy themes style against, and 0.4.1 completed it with base pipe support and per-line spans. The three releases since are compatibility fixes for R and R-devel.

◆ Where it's heading

The package reached its intended shape in the 0.4.x pair and has been static since. Its work now is reacting to the language and toolchain: a new pipe operator to highlight, an R-devel change to survive, a UTF-8 parsing crash routed around by simplifying the algorithm. Autolinking coverage, which drew steady contributions through 0.4.1, has not been extended since 2022.

◆ Prediction

Expect the next release to track another R or pandoc change rather than extend highlighting or linking.

highr is finished software: one-line releases every year or two

◆ Current state

highr does syntax highlighting for knitr output, and every release in this window is a single line of change. The most recent wraps hilight() output in xfun::raw_string() for nicer printing; before that, a rename of two LaTeX command macros and two bumps to the minimum R version. There is no feature work here at all.

◆ Where it's heading

This is a completed micro-package in the knitr ecosystem, maintained only to stay installable and consistent with its parent packages. Changes are triggered by knitr's needs or CRAN's requirements rather than by any plan of its own, and the gaps between releases run to years.

◆ Prediction

Expect the next release whenever knitr or CRAN requires one, with a similarly single-line changelog.
