highlight() no longer errors if a package imputed to
have been attached isn’t installed.
Correctly link requireNamespace(MASS)
(#151).
Supports new base pipe |> syntax (#126).
Every line get its own <span> to match pandoc
(#122).
Multi-line tokens (e.g. strings) now get a
<span> per line (#139).
Very long strings or other tokens are no longer truncated (@dmurdoch, #128).
Function calls (in inline and code blocks) will no longer to non-function topics (#135).
Re-exports detection no longer relies on name of .Rd
file (#134).
Link to correct topic with ::() and
utils::help() (@IndrajeetPatil, #131).
Generate correct link for Bioconductor vignettes (@zeehio, #145)
Messages, warnings, and errors now get a much more minimal style. Messages are styled the same way as output; and warnings and errors only style the “Warning” or “Error” text. This makes these types of output easier to read, and easier for package developers to style themselves.
Messages, warnings, and errors now retrieve their text using
conditionMessage(), which supports more advanced types of
conditions (@davidchall, #100).
The overall structure of the syntax highlighting has been
overhauled. Now each line is wrapped in a <span> with
class r-in (input code), r-out (output printed
to console), r-plot (plots), r-msg (messages),
r-wrn (warnings), and r-err (errors).
Additionally, the prompt (#>) is wrapped in a
<span class="r-pr">. Altogether, these changes should
give much more flexibility for styling with CSS (#90).
ANSI escapes no longer generate invalid HTML (#79).
Changes to better support for HTML widgets and rgl in pkgdown
(@dmurdoch, #78). In
particular, evaluate_and_highlight() now returns an
additional attribute containing all extra dependencies needed to render
the returned HTML.
Packages attached when you call library(package)
(including by the tidyverse), are now taken into account when
autolinking (#87).
In code blocks, custom infix operators are now autolinked (#89).
In inline code, infix operators are no longer autolinked; this lead to
too many false positives. You can still link with (e.g.)
?"-" (#86).
Inline calls with arguments (e.g. foo(1, 2)) are no
longer auto-linked, as intended and documented (#82).
Autolinking vignette(foo, package = "pkg") no longer
errors if pkg is not installed (#85).
Unusual help calls (e.g. help(a$b)), no longer
generate errors (#77).
Rare warning about incomplete final line in
autolink_url("pkgname::foo") is now suppressed (@dmurdoch,
pkgdown#1419).
href_package() is now exported (#103).
Auto-linking is more likely to succeed when the remote package is
not installed as downlit now looks for the URL using
tools::CRAN_package_db() for CRAN packages, and and
available.packages() for packages installed from non-CRAN
repos (@ARawles,
#108).
Functions in HTML <summary> elements are no
longer autolinked (@gadenbuie, #105).
When auto-linking vignette(foo), downlit now looks
for a vignette named foo in the packages it knows to be attached
(#61).
Can now force highlighting of any <pre> by
wrapping it inside a <div> with
class = "downlit". This is useful in cases where it may
otherwise be hard to set the class of the
<pre>.
In comments, \u2029 is converted to
\033 to make it possible to preserve ANSI escapes when
passed through xml2.
No longer errors on library calls with named but empty arguments.
Autolinking can use metadata stored in package itself with
pkgdown setting deploy.install_metadata; this is useful for
packages that only have private websites (@matthewstrasiotto, #29)
Autolinking guesses reference and article urls for pkgdown sites that haven’t set url (@krlmlr, #44).
R6 classes are autolinked when a new object is created i.e. in
r6_object$new(), r6_object will link to its
docs (#59, @maelle).
R6 methods are no longer autolinked as if they were functions of the same name (#54, @maelle).
classes_pandoc() and classes_chroma()
have been thoroughly revieweed to produce syntax highlighting as similar
as possible to RStudio.
downlit_html_path() has a more flexible XPath
identifying R code blocks, and a classes argument (#53,
@maelle, @cderv)
Trailing / are no longer stripped from URLs (#45,
@krlmlr).
Removed extra newline in <pre> output (#42,
@krlmlr).
