parsermd 0.2.0 (development version)

• 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
