Rmarkdown Versions Save

rmarkdown now requires knitr >= 1.43.

Get rid of the superfluous warning in find_pandoc() (thanks, @jszhao, #2527).

Removed the stringr dependency since it is used only once in the package and the equivalent base R code is simple enough (thanks, @etiennebacher, #2530).

For the output format option fig_crop: auto, it will now use the same logic as in knitr to decide if cropping is possible (yihui/knitr#2246).

Avoid corrupting input files by accident (thanks, @J-Moravec, #2534).

Fixed a bug that filenames beginning with - cause incorrect invocation of Pandoc (thanks, @mbaynton, #2503).

Documented how to merge output_format_dependency() to the output format (thanks, @atusy, #2508).

ioslides_presentation() now correctly works with new shiny 1.7.5 (thanks, @nicolasgaraycoa, #2514, @gadenbuie, #2516).

Added a new argument metadata to the pre_knit function in output_format() so that users will have access to the YAML metadata of the input document before knitting it (#2485). Please note that if you define pre_knit for a custom output format, you are strongly recommended to leave a ... argument in pre_knit, so we (rmarkdown package authors) are free to add more arguments to pre_knit without breaking your code. If your pre_knit function does not have the ... argument, you will get a warning.

Fixed file_scope being lost when extending output formats that considers the file_scope using output_format(). Merge behavior is to apply overlay file_scope function onto the result of base_format's file_scope function. This implies that file_scope gains second argument which receives the returned values of the base file_scope (thanks, @atusy, #2488).

Added output_format_dependency() which allows extending output format from within chunks (thanks, @atusy, #2462)

Fix an issue with shiny prerendered document where dependencies context were written twice leasing to parsing error (thanks, @gadenbuie, rstudio/learn#597, #2500).

find_external_resources() works with formats defining there own theme argument, like cleanrmd::html_document_clean(), not related to bslib supports (thanks, @gadenbuie, #2493, r-lib/pkgdown#2319).

Fixed version number comparison problems as requested by CRAN.

Using css with .scss and .sass file, or with a bslib theme, now works as expected with a shiny runtime (thanks, @cpsievert, #2443, #2447).

Add a pandoc_metadata_file_arg() function to match Pandoc's CLI flag --metadata-file.

Mentions that webshot or webshot2 is required to take screenshot of HTML widget. When not installed, an error message mentionning always_allow_html: true solution will be shown, but setting this is not the solution (quarto-dev/quarto-cli#4225).

html_dependency_jqueryui() updated to 1.13.2 from version bundled in shiny (thanks, @daschnerm, #2477).

Fix an issue with YAML header ending with a commented line containing incomplete yaml (thanks, @keithnewman, #2483).

When code folding is enabled in html_document(), the text on the button to show the content has been changed from "Code" to "Show", because the content to show is not necessarily code, e.g., yihui/knitr#2227.

Now HTML output formats use the Font Awesome HTML dependency from the fontawesome package instead of shipping an outdated version of Font Awesome in rmarkdown (thanks, @rich-iannone, #2451).

Fixed a bug caused by a change in the is_blank() function in xfun 0.38 (thanks, @andreahgsin, #2469).

The defunct tufte_handout() has been removed from rmarkdown. Please use tufte::tufte_handout() instead.

If an input path to rmarkdown::render() is a symbolic link, it is no longer resolved to its real path (thanks, @SamDM @jmw86069, #1508).

Make sure to avoid creating invalid paths when copying resources (thanks, @mnazarov, #2429).

Make sure logo is properly embedded in ioslides_presentation() when self_contained = TRUE (thanks, @mnazarov, #2428).

rmarkdown::render() argument output_file is now used for all output formats, if there is only one name for multiple output formats (thanks, @MaelAstruc, #2421).

Custom output formats can provide a custom function to convert Markdown input to the desired output format now. To do so, define the output format via output_format(pandoc = pandoc_options(convert_fun = function(...) {})). The default converting function is pandoc_convert() in this package. See the help page ?pandoc_options for more details.

rmarkdown::render_site() will now also look for index.rmd in addition to index.Rmd for custom site generator in YAML with site: (thanks, @kamalsacranie, #2409).

Icons in tabset dropdown are now correctly shown, including when self_contained: false (thanks, @cpsievert, #1697).
