Overview

About

Maintained by Colin RundelCRAN page ↗GitHub ↗Website ↗Issues ↗

An implementation of a formal grammar and parser for R Markdown documents using the Boost Spirit X3 library. It also includes a collection of high level functions for working with the resulting abstract syntax tree.

Changes in 0.2.0

**Breaking Change**: Migrated from S3/S4 classes to S7 classes for all AST node types (rmd_ast, rmd_chunk, rmd_heading, etc.)
**Breaking Change**: Removed deprecated rmd_subset() and related helper functions (rmd_get_node(), rmd_get_chunk(), rmd_get_markdown(), rmd_has_node(), rmd_has_chunk(), rmd_has_markdown()). Use rmd_select() with tidyselect syntax instead.
Added support for yaml chunk options - e.g. (#| echo: false)
Added support for fenced divs - e.g. (::: {.class} ... :::)
Added support for markdown code blocks
Added support for yaml expressions - e.g. (!expr)
Added support for parsing collections of Rmd and qmd files - see parse_qmd_collection() and parse_rmd_collection()
Removed option to not parse yaml - this is now always parsed. Based on this yaml node classes were simplified to just include rmd_yaml.
Added support for Pandoc-style ordered fenced attributes for code blocks, fenced divs, and spans
Added rmd_fenced_div_wrap() function to wrap selected nodes with fenced divs
Added rmd_insert() function to insert nodes relative to selected nodes
Added support for code block literals - e.g. ```{{r}}

Added support for 2ndary parsing to handle inline elements:
quarto shortcodes, inline code, and spans
Enhanced rmd_select() functionality and node manipulation
Added has_heading() helper function for selecting heading nodes using glob patterns
Added by_fenced_div() helper function for selecting fenced div sections using attribute patterns
Added keep_yaml argument to rmd_select() (defaults to TRUE) to automatically include YAML nodes in selections

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("parsermd", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("rundel/parsermd")

Development version from rundel/parsermd. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-parsermd

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-parsermd

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-parsermd

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
