quarto (development version)

  • quarto_preview() now explicitly returns the preview server URL (invisibly) and documents this behavior. This enables programmatic workflows such as taking screenshots with webshot2 or passing the URL to other automation tools (thanks, @cwickham, #233).

  • Added NA value detection in YAML processing to prevent silent failures when passing R’s NA values to Quarto CLI. Functions as_yaml() and write_yaml() now validate for NA values and provide clear error messages with actionable suggestions. This addresses issues where R’s NA values get converted to YAML strings (like .na.real) that Quarto doesn’t recognize as missing values, because they are not supported in YAML 1.2 spec. This is to help users handle missing data appropriately before passing to Quarto (#168).

  • Added add_spin_preamble() function to add YAML preambles to R scripts for use with Quarto Script rendering support. The function automatically detects existing preambles and provides flexible customization options through title and preamble parameters (#164).

  • quarto_create_project() gains a title argument to set the project title independently from the directory name. This allows creating projects with custom titles, including when using name = "." to create a project in the current directory (thanks, @davidkane9, #148). This matches with --title addition for quarto create project in Quarto CLI v1.5.15.

  • quarto_use_template() now supports using templates in another empty directory via the dir argument. However, the function will fail with a clear error message when used in non-empty directories, as interactive prompting is required and handled by Quarto CLI directly (requires Quarto 1.5.15+). Follow for quarto-dev/quarto-cli#11127 for change with --no-prompt behavior in future Quarto versions.

  • quarto_render(output_file = ) now sets the output-file Quarto metadata instead of the --output CLI flag. This allows the output file information to correctly be processed by Quarto, as if passed in a YAML header. e.g. it allows to support multiple output formats in the same render call. quarto_render(quarto_args = c('--output', 'dummy.html')) can still be used to set the --output CLI flag to enforce using the CLI flag and not the metadata processed by Quarto (#251, #43).

  • Added check_newer_version() function to check if a newer version of Quarto is available. The function compares the current Quarto version against the latest stable and prerelease versions. It is aimed for verbosity by default (verbose = TRUE), but verbose = FALSE can also be set for just checking update availability with TRUE or FALSE return values. Version information is cached per session for up to 24 hours to minimize network requests.

  • Added write_yaml_metadata_block() function to dynamically set YAML metadata in Quarto documents from R code chunks. This addresses the limitation where Quarto metadata must be static and defined in the document header. The function enables conditional content and metadata-driven document behavior based on R computations (thanks, @kmasiello, #137, #160).

  • Added debugging logic for quarto vignette engine to help diagnose issues with Quarto vignettes in pkgdown and other context (thanks, @hadley, #185). Set quarto.log.debug = TRUE to enable debugging messages (or R_QUARTO_LOG_DEBUG = TRUE environment variable). Set quarto.log.file to change the file path to write to (or R_QUARTO_LOG_FILE environment variable). Default will be ./quarto-r-debug.log Debug mode will be on automatically when debugging Github Actions workflows, or when Quarto CLI’s environment variable QUARTO_LOG_LEVEL is set to DEBUG.

  • Added a new_blog_post() function (thanks, @topeto, #22).

  • Make quarto_render(as_job = TRUE) wrapable (thanks, @salim-b, #105).

  • Quarto CLI will now correctly use the same R version than the one used to run functions in this package (#204).

  • Add quarto_available() function to check if Quarto CLI is found (thanks, @hadley, #187).

  • quarto_render() now correctly set as_job when not inside RStudio IDE and required rstudioapi functions are not available (#203).

  • Add several new wrapper function (thanks, @parmsam, #192):

  • quarto_create_project() offers better user experience now (thanks, @jennybc, #206, #153).

  • quarto_preview() gains a quiet argument to suppress any output from R or Quarto CLI (thanks, @cwickham, #232.)

  • Add some helpers function theme_brand_* and theme_colors_* to help theme with dark and light brand using some common graph and table packages (thanks, @gordonwoodhull, #234).

  • Add quarto.quiet options to allow more verbose error message when quarto_* function are used inside other package. For example, inside pkgdown for building Quarto vignettes. pkgdown sets quiet = TRUE internally for its call to quarto_render(), and setting options(quarto.quiet = TRUE) allows to overwrite this.

  • quarto_path() now returns a normalized path with potential symlink resolved, for less confusion with quarto_binary_sitrep() (thanks, @jennybc).

  • Fix an error with interactive prompt for extension approval (thanks, @wjschne, #212).

  • quarto_path() now correctly return NULL when no quarto is found in the PATH (thanks, @jeroen, #220, #221).

  • R_QUARTO_QUIET environment variable can be used to set quarto.quiet option, which overrides any quiet = TRUE argument passed to quarto_* functions. This can be useful to debug Quarto rendering inside other packages, like pkgdown. Overrides will also now happens for GHA debug logging.

  • Correctly report Quarto CLI error when background process call to quarto fails (thanks, @salim-b, #235)

quarto 1.4.4

CRAN release: 2024-07-20

quarto 1.4

CRAN release: 2024-03-06

  • This version is now adapted to Quarto 1.4 latest stable release.

  • Add registration of vignette engine to use quarto as a vignette builder, and use .qmd file as vignette. See vignette("hello", package = "quarto"). (thanks, @dcnorris, #57).

  • New quarto_binary_sitrep() checks possible difference in Quarto binary used by this package, and the one used by RStudio IDE (thanks, @jthomasmock, #12).

  • New is_using_quarto() to check if a directory requires using Quarto (i.e. it has a _quarto.yml or at least one *.qmd file) (thanks, @hadley, #103).

  • New quarto_create_project() calls quarto create project <type> <name> (thanks, @maelle, #87).

  • New quarto_add_extension() and quarto_use_template() to deal with Quarto extensions for a Quarto project. (thanks, @mcanouil, #45, @remlapmot, #42).

  • quarto_render() and quarto_inspect() gains a profile argument (thanks, @andrewheiss, #95, @salim-b, #123).

  • quarto_render() gains metadata and metadata_file arguments. They can be used to pass modified Quarto metadata at render time. If both are set, metadata will be merged over metadata_file content. Internally, metadata will be passed as a --metadata-file to quarto render (thanks, @mcanouil, #52, @maelle, #49).

  • quarto_render() and all other relevant functions gain a quarto_args argument. It allows to pass additional options flag to quarto CLI. This is for advanced usage e.g. when new options are added to Quarto CLI that would not be user-facing in this package’s functions (thanks, @gadenbuie, #125).

  • Add quiet argument in most functions to remove warnings and messages. It default to FALSE in most function to match with quarto CLI default.

  • In quarto_render(), execute_params now converts boolean value to true/false correctly as expected by quarto render (thanks, @marianklose, #124).

  • Error message now advises to re-run with quiet = FALSE because quarto_render(quiet = TRUE) will run quarto render in quiet mode (thanks to @gadenbuie, #126, @wlandau, #16).

  • rsconnect R package dependency has been moved to Suggest to reduce this package’s overall number of dependencies. rsconnect package is only required for publishing using quarto_publish_*() functions. Users will be prompted to install (when in interactive mode) if not installed.

  • Added a NEWS.md file to track changes to the package.
