This package provides a trimmed-down and reimagined implementation of R Markdown. It is much more lightweight, at the price of dropping some features. It does not depend on the R package knitr or the system package Pandoc.

Please consider this package experimental for now. The documentation is also very incomplete and still under development.

At the moment, you are recommended to install the development version from r-universe:

install.packages('litedown', repos = c('https://yihui.r-universe.dev', 'https://cloud.r-project.org'))

The function litedown::mark() is based on the R package commonmark, and renders Markdown to various output formats supported by commonmark, which are primarily HTML and LaTeX. MS Office formats are not supported.

R Markdown documents need to be knitted to Markdown before being rendered to a target output format. The function litedown::fuse() plays a role similar to knitr::knit() and rmarkdown::render(). It fuses program code with narratives, i.e., it executes code in the source document and interweaves results with narratives in the output document.

Try litedown::roam().

We want to limit the scope of this package. Most planned features have been implemented so far. Please feel free to file feature requests anyway, but we may be a little conservative when considering them (we will take votes into consideration, so please upvote features you like).
