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. 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).
Infix operators (e.g., %in% and %*%) are now linked to their documentation (#1082).
Function names can now be included in headers without spurious auto-linking (#948).
Links to external documentation now point to rdrr.io (#998).
News page recognises more version specfications (including the
“(development version)” now used by usethis) (#980).
Subdirectories are supported for assets (#939, @ijlyttle).
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).
Tweaking of HTML table classes was fixed (@yonicd, #912)
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 http://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 eliminating
Error 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).
Unexported functions and test helpers are no longer loaded (#789).
Selectors that do not match topics now generate a warning. If none of the specified selectors have a match, no topics are selected (#728).
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).
Navbar active tab highlighting uses a superior approach (suggested by
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).
\tabular{} no longer requires a terminal \cr (#664, #645).
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.
