pkgdown now uses the new downlit package for all syntax highlighting and autolinking (in both reference topics and vignettes). There should be very little change in behaviour because the code in downlit was extracted from pkgdown, but this makes it easier to use pkgdown’s nice linking/highlighting in more places (#1234).
pkgdown now uses the ragg::agg_png() device to generate example figures. This should be a little faster and produce higher quality output. Learn more at https://ragg.r-lib.org (#1320).
\special{} support inside \usage{} added to allow non-standard R usage syntax (@klmr, #1345).
#ifdef and #ifndef are now supported; the “current” OS is hard coded to “unix” to ensure reproducible output regardless of where you build the website (#1384).
Nested \subsection{}s now generate appropriate heading levels (h3, h4, h5 etc) (#1377), and get anchor links (#1389).
\preformatted{} no longer double escapes its contents (#1311).
build_articles() no longer sets the theme argument of the document format to NULL when as_is: true. This should allow it to work with a wider range of output formats including bookdown::html_vignette2() and friends (@GegznaV, #955, #1352).
When build_article() fails, it gives the complete failure message (#1379).
Markdown header attributes are now processed in all markdown files (@jonkeane, #1343)
The branch used for source linking can be configured by setting repo: branch: branch_name in _pkgdown.yml (@jonkeane, #1355):
autolink_html() is (soft) deprecated. Please use downlit::downlit_html_path() instead.
Highlighting of empty expressions works once more (#1310).
New deploy$install_metadata option in _pkgdown.yml. Setting it to true will store site metadata in the package itself, allowing offline access for packages that to autolink to the package’s website (@mstr3336, #1336).
You can now control the background colour of plots with the figures.bg option (it is transparent by default, and given a white background by css). See ?build_reference for an example.
HTML is automatically stripped from the page title (#1318).
Suppressing CRAN dates in news file now actually works.
All HTTP requests are now retried upon failure (@jameslamb, #1305).
Setting clean = TRUE in deploy_site_github() removes old files from the deployed site before building a new one (#1297).
Syntax highlighting works on Windows once more (#1282).
pkgdown no longer fails if your .Rd files have duplicated \aliases as were produced by an older version of roxygen2 (#1290).
Rendering empty .md file now returns empty string (#1285).
build_articles_index() is now exported to rapidly rebuild the index (#1281)
deploy_site_github() now accepts a host argument to specify alternate hosts (e.g., Github enterprise) (@dimagor, #1165) and once again works as intended on Travis-CI (@jimhester, #1276).
The articles index page and navbar have been overhauled. There are two major new features in this release:
The articles index page now displays article descriptions, taken from YAML metadata belonging to each article. This lets you provide more context about each article and describe why one might want to read it (#1227).
The articles navbar is now also controlled by the articles section in _pkgdown.yml. The ordering of the sections, and articles within them, control the order of the articles in the navbar, and you can use the new navbar field to control whether or not each section appears in the navbar (#1101, #1146).
The reference index now has two levels of heading hierarchy: title and subtitle (#327).
Tables of contents in sidebars now use bootstrap-toc; this considerably improves navigation for long articles and reference pages.
You can now control the links to source files (in reference pages and articles) and issues and users (in the NEWS) with new repo$url config option (#1238). This makes it easier to use pkgdown with GitHub enterprise, packages in subdirectories, and other source hosts (like bitbucket).
repo:
url:
home: https://github.com/r-lib/pkgdown/
source: https://github.com/r-lib/pkgdown/blob/master/
issue: https://github.com/r-lib/pkgdown/issues/
user: https://github.com/The individual components (e.g. path, issue number, username) are pasted on the end of these urls so they should have trailing /s.
You don’t need to set these links for GitLab, as pkgdown now detects GitLab urls automatically (since they use the same structure as GitHub) (#1045).
There’s much richer control over Open Graph and Twitter metadata for the whote site and for individual articles. See new vignette("metadata") for details (@gadenbuie, #936).
New deploy_to_branch() function to build and deploy a site to a branch, defaulting to gh-pages for use with GitHub Pages. This is used in our recommended GitHub action workflow for automatically building and deploying pkgdown sites for packages on GitHub (@jimhester, #1221).
Updated JS libraries: jquery 3.3.1 -> 3.4.1; bootswatch 3.3.7 -> 3.4.0; bootstrap 3.3.7 -> bootstrap 3.4.1; docsearch 2.6.1 -> 2.6.3; fontawesome 5.11.1 -> 5.12.1; headroom.js 0.9.44 -> 0.11.0; clipboard.js 2.0.4 -> 2.0.6 (@jayhesselberth).
Examples and Rmd now use exactly the same syntax highlighting strategy.
In examples and Rmd, calls of the form current_package::foo now get a local link (#1262).
\preformatted{} blocks are now highlighted and linked if they parse as R code (#1180).
library(pkgdown) is now automatically linked to the reference index for “pkgdown” not the documentation for library() (#1161).
help("topic") is now automatically linked to the documentation for “topic”, not to the documentation for help() (#1210)
build_home() no longer uses (unrendered) README.Rmd or index.Rmd if corresponding .md files are not found.
build_article() failures now print more information to help you debug the problem (#952).
The name of the vignette mapped to the “Get started” entry in the navbar is now more flexible. You can use an article (e.g articles/{pkgname}) and if your package has a . in its name you can replace it with - to generate a valid article name (e.g. the get started vignette for pack.down would be pack-down) (#1166).
deploy_to_branch() now correctly captures the commit SHA on GitHub Actions (@coatless, #1252).
deploy_to_branch(github_pages = TRUE) generates a .nojekyll to prevent jekyll ever executing (#1242).
CNAME is no longer generated by init_site(), but is instead conditionally by deploy_to_branch() when github_pages = TRUE. This is a better a fit because the CNAME file is only needed by GitHub pages (#969).
deploy_site_github() argument repo_slug has been deprecated and is no longer needed or used. (@jimhester, #1221)
See additional details in ?build_news:
You can optionally suppress the CRAN release dates added to the news page (#1118).
Multi-page news style gets a better yaml specification (the old style will continue to work so no need to change existing YAML).
A topic named index will not longer clobber the reference index (#1110).
Topic names/aliases on reference index are now escaped (#1216).
build_reference() gives better warnings if your _pkgdown.yml is constructed incorrectly (#1025).
New has_keyword() topic selector for reference. has_keyword("datasets") is particularly useful for selecting all data documentation (#760).
New lacks_concepts() can select topics that do not contain any of a number of specified concepts. (@mikldk, #1232)
Updated JS libraries: jquery 3.3.1 -> 3.4.1; bootswatch 3.3.7 -> 3.4.0; bootstrap 3.3.7 -> bootstrap 3.4.1; docsearch 2.6.1 -> 2.6.3 (@jayhesselberth).
Markdown conversion now explicitly allows markdown inside of HTML blocks; this was previously accidentally disabled (#1220).
A timestamp for the last site build is reported in pkgdown.yml (#1122).
build citation as specified by the textVersion argument of citEntry in the CITATION file (#1096, @yiluheihei)
build_site(), build_reference() and build_home() gain a parameter devel which controls whether you’re in deployment or development mode. It generalises and replaces (with deprecation) the existing document argument.
Development mode is optimised for rapid iteration and is the default for build_reference(). It uses pkgload::load_all() to load code directly from disk in order.
Deployment mode is slower, but guarantees correct results, and is the default for build_site(). It installs the package into a temporary library, and runs examples/articles in a new process.
build_reference() no longer runs devtools::document() (#1079) and build_home() no longer re-builds README.Rmd or index.Rmd. This makes the scope of responsibility of pkgdown more clear: it now only creates/modifies files in doc/.
build_home() now strips quotes from Title and Description fields when generating page metadata. Additionally, you can now override the defaults via the title and description fields in the home section of _pkgdown.yml (#957, @maelle).
vignette("linking") describes how pkgdown’s automatic linking works, and how to ensure that cross-package links point to the right place.
\examples{} rendering has been completely overhauled so it now first converts the entire mixed Rd-R block to R prior, and then evaluates the whole thing. This considerably improves the fidelity of the translation at a small cost of no longer being able to remove \donttest{} and friends (#1087).
\item{}s in \describe{} containing whitespace are translated correctly (#1117).
\dots and \ldots are translated to ... instead of the ellipsis, since they’re often found in code (#1114).
\tabular{} translation handles code better (@mitchelloharawild, #978).
\subsection{} contents are now treated as paragraphs, not inline text (#991).
\preformatted{} blocks preserve important whitespace (#951).
Links to online documentation for functions in code chunks are no longer displayed when printing (#1135, @bisaloo).
Updated fontawesome to v5.7.1. fontawesome 5 deprecated the fa prefix. If you have used custom icons in your navbar, you’ll should update them from (e.g.) fa fa-home to fas fa-home. Brands now have a separate prefix so fa fa-github becomes fab fa-github (#953).
The navbar is now automatically hidden with headroom.js.
The sticky behaviour of the navbar is now implemented in pure CSS instead of relying a the 3rd party javascript library (#1016, @bisaloo)
Favicons are now automatically built from a package logo (#949).
News page recognises more version specifications (including the
“(development version)” now used by usethis) (#980).
A default 404 page (404.html) is built, unless a custom .github/404.md is provided (#947).
build_article() now uses the raw vignette title as page <title> and og:title (@maelle, #1037).
build_home() now looks for license files spelled either as LICENSE or LICENCE (#972).
build_home() can find badges in paragraph coming after the comment <!-- badges: start --> (#670, @gaborcsardi, @maelle).
build_home() will add a community section to the sidebar if there is either a code of conduct (.github/CODE_OF_CONDUCT.md) or a contributing guide (.github/CONTRIBUTING.md) (#1044, @maelle).
build_reference() gains a topics argument which allows you to re-build only specified topics.
build_site(new_process = TRUE) gains a timeout, options(pkgdown.timeout = 10), that can be used to prevent stalled builds.
deploy_site_github(install = FALSE) makes it possible to opt out of installation.
dev_mode() now recognises 0.1.9000 as a development version of a package (this is an emerging standard we use for packages with backward incompatible changes) (#1101).
Restore accidentally deleted build_logo() function so that logos are once more copied to the website.
Fix to pkgdown.css so page header has correct amount of top margin.
content-home.html template is no longer used when the homepage is an .Rmd (Reverts #834. Fixes #927, #929)
deploy_site_github() now passes parameters to build_site() (@noamross, #922), and the documentation gives slightly better advice.
Correct off-by-one error in navbar highlighting javascript; now no navbar is highlighted if none match the current path (#911).
Restore accidentally removed docsearch.css file.
deploy_site_github() can be used from continuous integration systems (like travis) to automatically deploy your package website to GitHub Pages. See documentation for how to set up details (@jimhester).
build_favicon() creates high resolution favicons from the package logo, and saves them in pkgdown/. They are created using the https://realfavicongenerator.net/ API, and are better suited for modern web usage (e.g. retina display screens, desktop shortcuts, etc.). This also removes the dependency on the magick package, making automated deployment a little easier (@bisaloo, #883).
Users with limited internet connectivity can explicitly disable internet usage by pkgdown by setting options(pkgdown.internet = FALSE) (#774, #877).
rd2html() is now exported to facilitate creation of translation reprexes.
\Sexpr{} conversion supports multiple arguments, eliminating x must be a string or a R connection errors when using \doi{} (#738).
\tabular{} conversion better handles empty cells (#780).
\usage{} now supports qualified functions eliminatingError in fun_info(x) : Unknown call: :: errors (#795).
Invalid tags now generate more informative errors (@BarkleyBG, #771, #891)
The default footer now displays the version of pkgdown used to build the site (#876).
All third party resources are now fetched from a single CDN and are give a SRI hash (@bisaloo, #893).
The navbar version now has class “version” so you can more easily control its display (#680).
The default css has been tweaked to ensure that icons are visible on all browsers (#852).
Can now build sites for older packages that don’t have a Authors@R field (#727).
Remote urls ending in .md are no longer tweaked to end in .html (#763).
Bug report link is only shown if there’s a “BugReports” field (#855).
content-home.html template is now used when the homepage is an .Rmd (@goldingn, #787).
A link to the source inst/CITATION was added to the authors page (#714).
The display depth of vignette tables of contents can be configured by setting toc: depth in _pkgdown.yml (#821):
init_site() now creates a CNAME file if one doesn’t already exist and the site’s metadata includes a url field.
build_site() loses vestigal mathjax parameter. This didn’t appear to do anything and no one could remember why it existed (#785).
build_site() now uses colours even if new_process = TRUE (@jimhester).
build_reference() and build_site() get new document argument. When TRUE, the default, will automatically run devtools::document() to ensure that your documentation is up to date.
build_site() gains a new_process argument, which defaults to TRUE. This will run pkgdown in a separate process, and is recommended practice because it improves reproducibility (#647).
Improved display for icons: icons must be 30px and stored in top-level icons/ directory. They are embedded in a separate column of reference index table, instead of being inside a comment (!) (#607).
Added a keyboard shortcut for searching. Press shift + / (?) to move focus to the search bar (#642).
The Algolia logo is correctly shown in the search results (#673).
@jcheng5) which should mean that the active page is correctly highlighted in all scenarios (#660).
pkgdown.js is better isolated so it should still work even if you load html widgets that import a different version of jquery (#655).
vignette() calls that don’t link to existing vignettes silently fail to link instead of generating an uninformative error messages (#652). Automatic linking works for re-exported objects that are not functions (@gaborcsardi, #666).
Empty \section{}s are ignored (#656). Previously, empty sections caused error Error in rep(TRUE, length(x) - 1).
\Sexpr{} supports results=text, results=Rd and results=hide (#651).
Add inst/pkgdown.yml as a possible site configuration file so that packages on CRAN can be built without needing the development version (#662).
Default navbar template now uses site title, not package name (the package name is the default title, so this will not affect most sites) (#654).
You can suppress indexing by search engines by setting noindex: true pkgdown.yml (#686)
build_article() sets IN_PKGDOWN env var so in_pkgdown() works (#650).
build_home(): CITATION files with non-UTF-8 encodings (latin1) work correctly, instead of generating an error. For non-UTF-8 locales, ensure you have e.g. Encoding: latin1 in your DESCRIPTION; but best practice is to re-enode your CITATION file to UTF-8 (#689).
build_home(): Markdown files (e.g., CODE_OF_CONDUCT.md) stored in .github/ are copied and linked correctly (#682).
build_news(): Multi-page changelogs (generated from NEWS.md with news: one_page: false in _pkgdown.yml) are rendered correctly.
build_reference(): reference index shows infix functions (like %+%) as `%+%`, not `%+%`() on (#659).
Major refactoring of path handling. build_ functions no longer take path or depth arguments. Instead, set the destination directory at the top level of pkgdown.yml.
Similarly, build_news() no longer takes a one_page argument; this should now be specified in the _pkgdown.yml instead. See the documentation for an example.
