parsermd 0.2.0.9000

• Fixed a bug in parsing indented chunks with blank lines (#33)

• Revised the algorithm for determining node depth in the AST to better work with fenced divs

  • As a consequnce of these changes by_section() may yield slighly different results in some cases.

  • The rmd_node_depth() function was added to expose these depth calculations.

• Add support for pandoc fenced attributes for headings

• Added wrap_children argument to rmd_fenced_div_wrap() to control whether the selected nodes or their children are wrapped.

• Fixed a several bugs around handling of rmd_tibble methods (@ateucher)

parsermd 0.2.0 (2025-08-19)

• 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

parsermd 0.1.3 (2024-01-16)

• Minor fixes and updates to resolve CRAN warnings.

parsermd 0.1.2 (2021-05-20)

• Added new parser error reporting system

• Adopt testthat 3.0.0 for testing

• Added new render function to support rendering rmd_ast related objects

• Added support for raw attribute chunks (#13)

• Added rmd_source to support sourcing chunks directly into an environment.

• Added rmd_select which uses tidyselect based syntax as a replacement for rmd_subset.

• Soft deprecated rmd_subset, rmd_get_node, rmd_get_markdwon, and rmd_get_chunk.

parsermd 0.0.1
