Now blogdown::install_theme() downloads Hugo themes (from Github by default) as tarballs instead of zip archives, because unzip() is unable to extract files for certain themes (thanks, @jimvine, #433).
Disallow running blogdown::serve_site() multiple times in the same R session due to an RStudio IDE issue (thanks, @jennybc @daczarne @denizCvrl @lopierra, #404).
The “Filename” field in the “New Post” addin in RStudio will use the “Slug” value (if provided) to create the base filename (thanks, @maelle, #448).
For blogdown::build_site(method = 'html', run_hugo =TRUE), if the R script R/build2.R exists, it will be executed after Hugo has built the site. This can be useful if you want to post-process the site (thanks, @chrisjake, #458).
Added functions shortcode_open() and shortcode_close() so users can write the opening and closing shortcodes separately from the inner content, and the inner content can be processed by Pandoc (thanks, @tcwilkinson, #449).
blogdown no longer renders .Rmd documents within a packrat / renv library folder, for blog posts whose associated R libraries are managed by these packages (thanks, @kevinushey, #451).
The “Language” field in the “New Post” addin in RStudio now shows up regardless of the capitalization of the defaultContentLanguage parameter in config.toml (thanks @mpaulacaldas, #442).
Correctly identifies “Windows X.Y x64” as a 64bit operating system, so the extended version of Hugo can be installed (thanks, @anna-doizy, #461).
getOption('blogdown.author'). The “Subdirectory” field is now a select input instead of a text input, so you can choose one item from a full list of subdirectories instead of manually typing the directory path (thanks, @maelle @gadenbuie, #432).new_site() and install_theme() will check the minimal Hugo version specified by the theme, and automatically update Hugo if the current installed version of Hugo is not sufficient (thanks, @apreshill, #391).blogdown.hugo.args, which should be a character vector with additional flags to be passed to the hugo system command via hugo_build(). For example, options(blogdown.hugo.args = '--minify') will use minification on the final rendered output. More available flags in the hugo documentation (thanks, @jozefhajnala, #382).options(blogdown.warn.future = FALSE) (thanks, @Chucheria on Twitter, #377).blogdown.filename.pre_processor, which can be a function with a single argument (the post title) that returns a pre-processed string to be used to generate the post filename. For example, if you set options(blogdown.filename.pre_processor = function(x) stringi::stri_trans_general(x, "any-latin; nfd; [:nonspacing mark:] remove; nfc")), Cyrillic characters in a post title can be converted to ASCII, and the result string will be used for generating the post filename (thanks, @novica, #349).relativeURLs will be set to true automatically (thanks, @nwstephens, #124).install_hugo(..., extended = TRUE) (thanks, @rgaiacs, #363).The slug field in the “New Post” RStudio addin will no longer be automatically changed if the user has manually changed it once (thanks, @eliocamp, #347).
Added multilingual support in the “New post” RStudio addin (thanks, @novica #344, @Guilz #323).
You can create a new post as the index file of a Hugo page bundle via blogdown::new_post() or the RStudio addin “New Post” if you set options(blogdown.new_bundle = TRUE). One benefit of using a page bundle instead of a normal page is that you can put resource files associated with the post (such as images) under the same directory of the post itself. This means you no longer have to put them under the static/ directory, which has been quite confusing to Hugo beginners (thanks, @DavisVaughan @romainfrancois @apreshill, #351).
Added an argument empty_dirs to new_site() so that you can preserve the empty directories via blogdown::new_site(empty_dirs = TRUE). By default, empty directories will be deleted when a new site is created (thanks, @apreshill, rstudio-education/arm-workshop-rsc2019#8).
Added a global option blogdown.files_filter to allow users to decide which Rmd files to be rebuilt (this option can be set in .Rprofile). The default filter is blogdown:::timestamp_filter, i.e., only Rmd files which are older than their output files will be recompiled when rebuilding a site. You can set options(blogdown.files_filter = blogdown:::md5sum_filter) to use a different filter based on MD5 checksums, i.e., only rebuild an Rmd file if its MD5 checksum has changed. The checksums of Rmd files are saved in the file blogdown/md5sum.txt under the website root directory (thanks, @jonathan-g, #341).
kind of new_post() has been changed from 'default' to '', which means this function will respect Hugo’s default order of looking for the archetype. The Archetype dropdown menu of the RStudio addin “New Post” was changed accordingly, and this menu will also list archetypes in themes (thanks, David Daza, https://stackoverflow.com/questions/53309582/53341795#comment93989876_53341795).2018-07-23 to 2018-07-28, the post file 2018-07-23-hello-world.md can be renamed to 2018-07-28-hello-world.md.draft: yes to YAML only when options(blogdown.draft.output = TRUE) is set (thanks, @ConorIA, #312).Added a new RStudio addin “Touch File” to update the modification time of a file, which can be useful when you want to force rebuilding a certain Rmd post after running serve_site() (#294).
Added an RStudio addin “Quote Poem” to quote a poem using the Markdown syntax (https://yihui.org/en/2018/06/quote-poem-blogdown/).
Added a new function shortcodes(), which is a vectorized version of shortcode(). For example, you can embed multiple tweets (thanks, @maelle, #307).
Added an argument ignore to build_dir() to ignore output filenames when testing if the Rmd file is newer than its possible output files. By default, *.Rproj files are ignored (thanks, @chepec, #308).
Added a global option blogdown.draft.output. If options(blogdown.draft.output = TRUE) is set, a field draft: yes will be appended to the YAML metadata of the HTML output file from an Rmd post, unless the Rmd post has already set the draft option. This means the output files are always drafts unless you explicitly set draft: no in the YAML metadata of Rmd posts (thanks, @mwaldstein, #305).
Applied a workaround for the bug in the Rscript command: https://stat.ethz.ch/pipermail/r-devel/2018-April/075897.html (reported from https://stackoverflow.com/q/50077412).
The TOML metadata in new posts may fail to be converted to YAML (thanks, @apreshill, #301).
When editing the config.toml file on Windows, serve_site() could fail with an error message '---did you forget a '#'? at line 1>seImpl(path.expand(input), verbose, fromFile): Unidentified trailing character' (thanks, @rhobis, #302).
Added a title_case argument to the new_post() function; if TRUE, the post title will be converted to title case. See ?blogdown::new_post for details.
Added a hostname argument to install_theme() and new_site(), as a complement to the theme argument. The default hostname is 'github.com'; if you have access to GitHub Enterprise, you can use this to specify it instead (thanks, @ijlyttle, #264).
The new_post addin now lets you choose an archetype. See https://gohugo.io/content-management/archetypes/ for more details (thanks, @lcolladotor, #173).
Added a new RStudio addin (insert_image) for inserting external images into blog posts (thanks, @lcolladotor, #269). If you use options(blogdown.insertimage.usebaseurl = TRUE), it adds the baseurl so that RSS feeds will include the images and be properly displayed in websites such as RBloggers (#275). You will need to publish the images so that they are displayed in a local preview and will need to keep in mind some drawbacks discussed in https://github.com/rstudio/blogdown/pull/275.
The theme argument of install_theme() and new_site() now accepts a full URL to a theme’s repository zip file. This can be used to install themes from other web-based git hosts, like GitLab and Bitbucket (thanks, @gadenbuie, #271).
You may download the zip archive or tarball of the Hugo installer from Github by yourself, and pass the path to install_hugo() to install it, e.g., blogdown::install_hugo('hugo_0.38_Windows-64bit.zip') (thanks, @shrektan, #288).
kind argument (i.e., the archetype) of new_content() now works with files that end in .Rmd and .Rmarkdown. The archetype still has to end in .md for Hugo to work with it (thanks, @lcolladotor, #261).yihui/hugo-lithium-theme was renamed to yihui/hugo-lithium, and the default theme argument value was changed accordingly (thanks, @rorynolan, #291).install_theme() may signal the error “The theme already exists” by mistake (thanks, @YizhouZheng, #230).
A warning will be issued if two versions of Hugo are found (thanks, @mingsnu, #235).
Plots are missing if a post filename contains multibyte characters (thanks, @dongzhuoer, #233).
blogdown::serve_site() now (#169).serve_site() failed to parse baseurl in config.toml when it contains comments (thanks, @ummel, https://github.com/rbind/support/issues/62).
Three dashes in the beginning and/or end of config.yaml are ignored (thanks, @andrewheiss, #194).
The R startup profile .Rprofile under the website project root directory should be respected when building R Markdown posts (thanks, @eisioriginal, #222).
