CHANGES IN blogdown VERSION 1.20

CHANGES IN blogdown VERSION 1.19

CRAN release: 2024-02-01

  • Fixed the bug that shortcodes were mangled when there are raw HTML blocks in the Markdown output from R Markdown (thanks, @Redcozmo, #759).

CHANGES IN blogdown VERSION 1.18

CRAN release: 2023-06-19

CHANGES IN blogdown VERSION 1.17

CRAN release: 2023-05-16

  • The RStudio addin “Quote Poem” adds > to every line instead of only the beginning of every paragraph now.

  • The “New Post” addin will verify if Hugo has been installed before launching (thanks, @LukasWallrich, #750).

CHANGES IN blogdown VERSION 1.16

CRAN release: 2022-12-13

  • Added the command-line option --preserve-tabs to the pandoc_args argument of blogdown::html_page(), so that tabs are preserved by default in code blocks (thanks, @amarakon, #740).

  • Fixed a bug that caused config.toml.bak.toml to be recognized as the config file mistakenly, which led to an obscure error (thanks, @CerebralMastication, #742).

  • This package requires R >= 3.5.0 now.

CHANGES IN blogdown VERSION 1.15

CRAN release: 2022-11-07

  • Restored the old default options(blogdown.method = "html") (thanks, @pachadotdev, #739).

CHANGES IN blogdown VERSION 1.14

CRAN release: 2022-11-04

  • For R Markdown posts, the default rendering method has been changed from html to markdown. If options('blogdown.method') is not set, it will be set to 'markdown'. This option will also be set in .Rprofile for newly created sites via blogdown::new_site(). Users who have already set this blogdown.method option will not be affected. The motivation for this change is that markdown output often works better with Hugo themes and is less surprising, even though the html method allows for richer Markdown features because of Pandoc (thanks, @SebPouliot #737, @austinwpearce #591).

  • When rendering Rmd posts that involve time-consuming and intensive computing while serving the site, the hugo process can die (for unknown reasons). Now the hugo process will be suspended before rendering Rmd posts, and resumed after the rendering is done. Hopefully this will keep the server process alive (thanks, @XiangyunHuang, https://d.cosx.org/d/423509).

CHANGES IN blogdown VERSION 1.13

CRAN release: 2022-09-24

CHANGES IN blogdown VERSION 1.12

CRAN release: 2022-09-15

CHANGES IN blogdown VERSION 1.11

CRAN release: 2022-08-09

  • blogdown::check_site() also checks index.Rmd in the website root directory now (thanks, @maelle, #719).

  • The build_rmd argument of blogdown::build_site() also accepts absolute paths under the content directory now (thanks, @maelle, #717).

  • Fixed a bug that blogdown::serve_site() fails with the ignoreErrors option is configured as an array in config.yaml (thanks, @CongLiu-CN, #714).

  • Fixed a bug for multilingual sites that have separate contentDir settings for each language, in which case blogdown::new_post() and the “New Post” addin in RStudio may create new post files in wrong locations (thanks, @pensivedog, #712).

  • Fixed an issue with the wowchemy/starter-hugo-online-course theme (thanks, @bayeslearner, #722).

  • Archetypes in modules were not found previously in the “New Post” addin (thanks, @atakanekiz, #670).

  • blogdown::install_theme() works with themes that contain git submodules now (thanks, @pensivedog, #712).

  • The global option blogdown.warn.future has been removed. It was originally introduced in blogdown 0.12 to warn against posts that have dates in the future, which can cause posts to be ignored by Hugo. This option was removed because blogdown::check_site() can identify this problem.

  • Fixed a problem with the “New Post” addin in RStudio (thanks, @pingao777, #394). It did not work for sites that are not based on Hugo (e.g., Jekyll or Hexo).

CHANGES IN blogdown VERSION 1.10

CRAN release: 2022-05-10

  • For Jekyll sites, a new global option can be used to determine whether to run jekyll directly or use the bundler gem to run jekyll (i.e., bundle exec jekyll). If you prefer the latter way, you may set options(blogdown.jekyll.bundler = TRUE) before running blogdown::serve_site() (thanks, @pat-s, #695).

  • Adapted to some breaking changes in the wowchemy academic theme again (thanks, @bjsmith, #704). As mentioned in blogdown v1.4, we recommend blogdown users to consider using the hugo-apero theme when creating new sites. This theme is maintained by blogdown authors and much more stable.

  • Updated documentation to mention that the tweet shortcode (or the R wrapper function blogdown::shortcode('tweet')) will require the Twitter username for Hugo >= v0.89.0. Previously only the tweet ID is required, e.g., {{< tweet 852205086956818432 >}}, but now it also requires the user, e.g., {{< tweet user="jtleek", id="852205086956818432" >}} (thanks, @lcolladotor, #701).

CHANGES IN blogdown VERSION 1.9

CRAN release: 2022-03-28

NEW FEATURES

  • The RStudio addin “Insert Image” also works when the current document in RStudio does not belong to any site projects. Previously, it would throw an error if it is not used inside a site project. Now it works in any document in RStudio (thanks, @yufree, rstudio/rmarkdown#2280).

BUG FIXES

CHANGES IN blogdown VERSION 1.8

CRAN release: 2022-02-16

NEW FEATURES

  • The bookdown config file _bookdown.yml under the site root directory is recognized now. For example, you can customize the figure label in _bookdown.yml (thanks, @luofeicq, rbind/yihui#167).

  • The internal function scan_yaml() uses cache in the current R session now. Other functions (e.g., find_yaml(), count_yaml(), and the “New Post” addin in RStudio) based on this function should be much faster when there are a lot of files to scan for more than once.

BUG FIXES

  • For Hugo versions from 0.89.0 to 0.89.2, new_content() failed to identify new content files if they were created with archetypes (thanks, @maelle, #685).

  • When creating new posts, YAML metadata inherited from Hugo archetypes could be mangled (thanks, @llrs, #684).

CHANGES IN blogdown VERSION 1.7

CRAN release: 2021-12-19

MINOR CHANGES

  • The version argument of find_hugo() allows for the prefix v in the version number now, e.g., find_hugo('v0.89.2') is equivalent to find_hugo('0.89.2'). This is also true to other functions that use find_hugo(), such as remove_hugo().

  • Clarified write_toml()’s error message that Hugo >= 0.37 is required to run this function (thanks, @pssguy, #665).

BUG FIXES

  • install_hugo() did not work for Hugo v0.20.3.

  • new_post() failed to correctly detect the path of the new post with Hugo >= 0.89.3 (thanks, @rcarboni, #667).

  • Deal with the new security policy in Hugo 0.91.0 by renaming the internal environment variable BLOGDOWN_POST_RELREF (in the shortcode layouts/shortcodes/blogdown/postref.html) to HUGO_BLOGDOWN_POST_RELREF (thanks, @Nitheshnirmal #672, @gergiu #673).

CHANGES IN blogdown VERSION 1.6

CRAN release: 2021-11-09

NEW FEATURES

  • The config file config/_default/config.yaml (or .toml) is supported now; blogdown no longer requires that config.yaml (or .toml) is under the root directory of the website project. Note that if config.yaml is present under both the root directory and the config/_default/ directory, blogdown will only recognize the former, and you may want to delete the former if you actually intend to use the latter (thanks, @Athanasiamo @maelle #611, @diegouriarte #598).

  • install_hugo() can automatically correct the version number X.Y to X.Y.0 when X.Y does not exist but X.Y.0 does. For example, install_hugo('0.87') will actually install the version 0.87.0.

  • Added a global option blogdown.server.first, which can be specified as a function to run before serving the site. For example, you can sync a JS file to the static/ directory with options(blogdown.server.first = function() { file.copy('../foo/bar.js', './static/js/', overwrite = TRUE) }) each time before you serve the site.

  • Added arguments arch and os to install_hugo() so that users can choose the architecture and operating system names manually. For example, blogdown::install_hugo(extended = FALSE, arch = '64bit', os = 'FreeBSD') would install hugo_*_FreeBSD-64bit.tar.gz (* denotes a version number) from https://github.com/gohugoio/hugo/releases.

  • Added a new function hugo_installers() to print out the information about available Hugo installers of a certain version. This can be helpful when install_hugo() fails, e.g., the installer for a certain os or arch is not available.

MAJOR CHANGES

  • When creating new posts (either with new_post() or the RStudio addin “New Post”), the default post filename will be generated from the post title but it will exclude all non-alphanumeric characters. Previously the exclusion of these characters failed under certain locales (e.g., UTF-8 or a locale that has native support for multibyte characters). Now the default filename will no longer contain non-alphanumeric characters except dashes (thanks, yingjie, https://d.cosx.org/d/422702).

MINOR CHANGES

  • The intermediate files .knit.md$ and .utf8.md$ no longer need to be ignored in ignoreFiles in the Hugo config file now. There is no harm to ignore them anyway. If you have ignored them, you do not need to update your config (#609).

BUG FIXES

  • The global option blogdown.subdir_fun can be a function that takes the post title as the input and returns a path of subdirectory under which the new post is to be created via the “New Post” addin in RStudio. The “New Post” addin failed to add the subdirectory defined by this function to the choices of the “Subdirectory” select input if the subdirectory does not exist in the choices, therefore it could not really be used. Now the subdirectory is corrected added, and can be used (thanks, @datawookie, #656).

  • install_hugo() stopped working with Hugo v0.89.0 (thanks, @martinolmos, #664).

  • On Windows, new_post() may fail to open the new post if the filename contains multibyte characters (thanks, yingjie, https://d.cosx.org/d/422702).

CHANGES IN blogdown VERSION 1.5

CRAN release: 2021-09-02

NEW FEATURES

  • Added a new function check_vercel() to check the Vercel config vercel.json, and a new function config_vercel() to create vercel.json that contains the Hugo version (thanks, @chuxinyuan, #648). Vercel (https://vercel.com) is service similar to Netlify.

  • Added an argument time to new_post() to optionally include the local time in the date field of the new post with new_post(time = TRUE). The value of this argument can also be set via the global option in .Rprofile, e.g., options(blogdown.time = TRUE) (it is FALSE by default). See the help page ?blogdown::new_post for more information (thanks, @earfanfan, #625).

BUG FIXES

CHANGES IN blogdown VERSION 1.4

CRAN release: 2021-07-23

NEW FEATURES

  • check_config() now checks for baseURL that only provides a domain name but lacks the https (or http) protocol, e.g., baseURL: example.com/ is typically not a valid URL, but should be https://example.com/ instead (thanks, @apreshill, #616).

BUG FIXES

  • Fixed a new issue with blogdown::new_site(theme = "wowchemy/starter-hugo-academic") (#638). To avoid similar issues with the academic theme in the future, we recommend that you consider using the hugo-apero/hugo-apero theme instead.

  • install_hugo() can install the correct version of Hugo on a machine with an ARM processor now (thanks, @r-saikat, #636).

  • clean_duplicates() now correctly deletes duplicated .html file instead of .md when blogdown.method option is set to markdown (thanks, @apreshill, #628).

  • clean_duplicates() also correctly deletes unused directories like *_files/header-attrs associated with .html output files (thanks, @apreshill, #632).

CHANGES IN blogdown VERSION 1.3

CRAN release: 2021-04-14

NEW FEATURES

MAJOR CHANGES

  • The method argument of build_site() has been removed (it was defunct in blogdown v1.2). Please set the build method in the global option options(blogdown.method = ) instead.

  • The use_brew argument of install_hugo() has been removed.

BUG FIXES

CHANGES IN blogdown VERSION 1.2

CRAN release: 2021-03-04

NEW FEATURES

  • Added the argument force back to install_hugo(). If the specified version of Hugo has been installed, install_hugo() will not reinstall it unless force = TRUE (thanks, @cderv, #575).

  • The new option options(blogdown.knit.serve_site = FALSE) can be used to prevent blogdown from starting the web server automatically when the Knit button is clicked in RStudio and the site has not been served yet (thanks, @Athanasiamo, #572). By default, the web server will be started (if not already started) so the page being knitted can be previewed.

  • Added a new global option blogdown.site_root, which can be used to specify the root directory of the website. This can be useful when the website source directory is not the root directory of a project but a subdirectory (thanks, @wjakethompson, #581).

  • Added a new global option blogdown.markdown.format to allow users to customize Pandoc’s Markdown output format. When using the file extension .Rmarkdown or options(blogdown.method = 'markdown'), an R Markdown file is first compiled to Markdown. This Markdown file needs to go through another conversion when it contains Markdown features that are only available to Pandoc but not other Markdown renderers such as Hugo/Goldmark, such as citations or fenced Divs. The new global option controls the Pandoc output format. By default, its value is c('gfm', '+footnotes', '+tex_math_dollars') for Pandoc 2.10.1 and later when the Markdown document contains bibliography or fenced Divs, otherwise it is NULL. With earlier versions of Pandoc, it will be c('gfm') only. If you want the conversion to be always performed, you may set this global option to a value that is not NULL, e.g., options(blogdown.markdown.format = c('gfm', '+footnotes', '+tex_math_dollars', '+smart')).

MAJOR CHANGES

  • The method argument of build_site() is now defunct (it was deprecated in blogdown v1.0), and will be removed in a future version. Please set the build method in the global option options(blogdown.method = ) instead.

  • The use_brew argument of install_hugo() is defunct now, and will be removed in a future version.

  • The update_hugo() function is defunct. Please use install_hugo() instead.

  • The scripts R/build.R and R/build2.R are no longer executed when a document is compiled via the Knit button in RStudio. They will be executed only when building the whole site via build_site() (e.g., Ctrl/Cmd + Shift + B in RStudio).

BUG FIXES

  • check_config() will now correctly check for both missing and unneeded values in the ignoreFiles field in the config file.

  • When serving the site with blogdown::serve_site() with 'blogdown.knit.on_save' option being TRUE, Rmd files in renv/ or packrat/ folder are now correctly ignored and not rebuilt (#593).

  • For .Rmarkdown posts, the Markdown extension tex_math_dollars should not be used when post-processing the .markdown output file with Pandoc < v2.10.1 (thanks, @lz100, #578).

  • The new_post() function does not work with bundle archetypes (thanks, @maelle, #577).

  • install_theme() will now remove the .github/ folder if one exists in the theme repo as it is only useful to the theme developer (#584).

  • Plots generated from R code chunks in posts cannot be previewed on RStudio Server (thanks, @cderv @datawookie #587).

  • The error “RStudio is not running” should be suppressed when building the site in a non-interactive R session (thanks, @kcarnold, #596).

  • The theme gcushen/hugo-academic is now correctly automatically redirected to wowchemy/starter-academic with correct default git branch when installing with new_site() or install_theme().

  • Also try to move config/_default/config.yaml to the root dir when installing a theme. Previously, only config.toml was moved (thanks, @andreashandel, #546).

  • When installing a theme, delete figure shortcodes that uses http resources because the figure paths could be mangled on Windows (thanks, @andreashandel, #546).

MINOR CHANGES

  • When clicking the Knit button in RStudio to knit a post, the normal knitting process is shown (such as the progress bar) instead of being suppressed (thanks, @Athanasiamo, #572).

  • The command blogdown:::preview_site() is no longer called or displayed in the R console when users click the Knit button after the server has been started (thanks, @apreshill, #543).

  • The config option ignoreErrors will be set to "error-remote-getjson" when running blogdown::serve_site(). This is to prevent Hugo errors in fetching remote resources such as Tweets (thanks, Fan Yuan https://d.cosx.org/d/422065 and dhonda https://stackoverflow.com/q/64601786/559676).

CHANGES IN blogdown VERSION 1.1

CRAN release: 2021-01-19

NEW FEATURES

  • Added new arguments args, baseURL, and relativeURLs to the hugo_build() function to allow users to pass more command-line arguments to Hugo and adjust the configurations baseURL and relativeURLs temporarily when building a site.

  • Added the ... argument to build_site(), to pass more arguments to the hugo_build() function, e.g., blogdown::build_site(relativeURLs = TRUE).

  • Added a global option blogdown.server.verbose to print the web server messages in real time when the server is running. Once enabled (via options(blogdown.server.verbose = TRUE)), you will see messages in the R console like “Change detected, rebuilding site” whenever you make changes to any files (thanks, @apreshill @cderv, #555).

  • Added a new global option blogdown.protect.math (defaults to TRUE) to control whether to protect LaTeX math expressions in a pair of backticks when the post output format is Markdown instead of HTML. The reason to protect math expressions is to avoid the Markdown renderer’s treatment of the math content as normal Markdown content, which may mangle the math expressions. If the math expression is protected, it needs to be unprotected later. See https://yihui.org/en/2018/07/latex-math-markdown/ for more information. Note that this option is only relevant to those who use the source format .Rmarkdown or the build method options(blogdown.method = 'markdown') (thanks, @bensoltoff #466, @mrkaye97 #567).

BUG FIXES

  • bundle_site() also moves the .html output files and the *_files//*_cache/ directories associated with .Rmd source posts to page bundles. Previously, only .Rmd files are moved (thanks, @llrs, #568).

  • Fixed a bug of install_theme() when the theme archive contains theme files directly instead of a theme folder (thanks, Stefan Musch, https://stackoverflow.com/q/65702805/559676).

  • Fixed a bug that causes HTML widgets to fail to render in the Markdown output files with htmltools >= 0.5.1.

  • Fixed a bug on Windows that causes check_gitignore() to error when it shouldn’t (#571).

MAJOR CHANGES

  • When the site is rendered via a call to rsconnect::deploySite() (e.g., when you call rmarkdown::publish_site(render = TRUE)), blogdown::build_site() will use the argument relativeURLs = TRUE, to make Hugo generate relative URLs that work with any base URL (note that this depends on how well a specific Hugo theme supports relative URLs).

MINOR CHANGES

  • check_netlify() and check_config() do not open files anymore in the IDE if no TODO items were found in them (#569).

  • The internal functions md5sum_filter() and timestamp_filter() have been removed. They were renamed to filter_md5sum() and filter_timestamp(), respectively, and exported in blogdown 1.0. Please use these exported functions instead if you relied on the internal functions previously.

CHANGES IN blogdown VERSION 1.0

CRAN release: 2021-01-09

NEW FEATURES

  • Added a function check_site() to provide diagnostics for a website project, which may help reveal potential problems in various places. It runs a series of checks on the config file (config.yaml or config.toml), the .gitignore file, the Hugo installation and version, the netlify.toml file, and content files. See the help page ?blogdown::check_site for more info.

  • Documented and exported the internal function find_hugo() to find the Hugo executable. If multiple versions of Hugo are installed, find_hugo() can also find a specific version of Hugo, e.g., blogdown::find_hugo('0.25.1'). You may use blogdown::find_hugo('all') to find all possible versions of Hugo currently installed.

  • Added a function remove_hugo() to remove Hugo (thanks, @cderv, #504).

  • The file format .Rmarkdown supports HTML widgets and citations now, just like the .Rmd format. If you are not familiar with the .Rmarkdown format, you may see https://bookdown.org/yihui/blogdown/output-format.html.

  • Added a function config_netlify() to help users create the config file netlify.toml for Netlify. It sets the build commands properly for different deploy contexts, and writes the local Hugo version to the config file, so make sure Netlify uses the same version of Hugo as your local environment. See the help page ?blogdown::config_netlify for details.

  • Added a function config_Rprofile() to help create or modify the .Rprofile file. In particular, it will try to set the option blogdown.hugo.version in it, if the option has not been set. See the help page ?blogdown::config_Rprofile for details.

  • Added an argument netlify = TRUE to new_site() to create netlify.toml by default.

  • Added an argument .Rprofile = TRUE to new_site() to create the .Rprofile file by default. This file contains a few sample global options that could affect blogdown’s behavior, e.g., the option blogdown.hugo.version is set to the current Hugo version, so that a site will not be affected by future Hugo updates and will always use the fixed version of Hugo. This file is provided so that users are better aware of some of these options, and can change them if they want.

  • Exported the function filter_newfile(), which returns paths of source files that have not been knitted (i.e., their output files do not exist).

  • The build_rmd argument of build_site() can take a function as its value now (thanks, Tyler Smith). The function is expected to take a vector of paths of all R Markdown files under the content/ directory, and returns a vector of paths of R Markdown files to be built. This argument can also take one of the aliases "timestamp", which is equivalent to blogdown::filter_timestamp, newfile (equivalent to blogdown::filter_newfile), and "md5sum" (equivalent to blogdown::filter_md5sum). For example, blogdown::build_site(build_rmd = "timestamp") means to build all R Markdown files if they are older than their output files (by comparing modification times).

  • When opening a blogdown website project in RStudio, you can specify a number of files to be automatically opened every time via the global option blogdown.initial_files in your .Rprofile. This option can take a vector of file paths, e.g., options(blogdown.initial_files = c('config.yaml', '.Rprofile', 'content/post/my-first-post/index.Rmd')) (files that do not exist will be ignored). Alternatively, this option can take a function that returns a vector of file paths, e.g., options(blogdown.initial_files = blogdown:::initial_files).

  • Added a new argument .site_dir to serve_site(), so users will be able to specify the site root directory (thanks, @Bijaelo, #527).

  • Added a new argument force to new_site() to allow users to create a new site under a nonempty directory with force = TRUE if they are sure the site can be safely created under the directory (i.e., Hugo will not possibly override existing files). In an interactive R session, it will ask users if they want force = TRUE when the directory is not empty.

MAJOR CHANGES

  • install_hugo() no longer installs Hugo via Homebrew by default on macOS, but just downloads binaries from Hugo’s Github releases, which gives you a stable version of Hugo. The use_brew argument of install_hugo() has been deprecated. Installing Hugo via Homebrew often leads to accidental updates of Hugo, which may break your existing sites. If you must install Hugo via Homebrew and want to fix its version, you can run brew pin hugo, so it will not be updated by accident in the future (e.g., via brew upgrade).

  • By default, install_hugo() installs Hugo to ~/.local/share/Hugo on Linux now, instead of ~/bin.

  • install_hugo() installs the hugo executable to a directory with the directory name being the Hugo version number, e.g., ~/Library/Application Support/Hugo/0.76.5, or ~/.local/share/Hugo/0.25.1. This makes it possible to install multiple versions of Hugo on the same computer.

  • When starting to serve the site, serve_site() will compile Rmd files that do not have output files initially (thanks, Hannah Wang, https://stackoverflow.com/q/64420476/559676).

  • The default value of the global option blogdown.serve_site.startup was changed from TRUE to FALSE, meaning that the site will not by served by default when the RStudio project is first opened. If you want the previous behavior, you may set options(blogdown.serve_site.startup = TRUE) in your .Rprofile.

  • The method argument of build_site() was deprecated. The build method can only be specified via the global option blogdown.method now, e.g., you may set options(blogdown.method = 'custom') in .Rprofile. A new possible build method named markdown was added. When you set options(blogdown.method = 'markdown'), .Rmd posts will be compiled to .md (by default, they are compiled to .html since the default option is blogdown.method = 'html'). This provides another way to render R Markdown to Markdown instead of HTML. Previously, the only way to achieve this was to use the file extension .Rmarkdown (this way still works).

  • The function update_hugo() and the argument force of install_hugo() have been deprecated. If you want to update Hugo to a newer version, you can call install_hugo() and specify a desired version.

  • The functions md5sum_filter and timestamp_filter have been renamed to filter_md5sum and filter_timestamp, respectively.

BUG FIXES

  • serve_site() fails to start the server when the config file contains a baseURL value that includes a subpath in it (thanks, @giabaio #254, @ShixiangWang #494).

  • serve_site() and hugo_build() fail to resolve URLs when relativeURLs is configured to true (thanks, @TianyiShi2001, #506).

  • The “Insert Image” addin works with posts that are index pages of leaf bundles now. The images are added to the images/ folder under the post directory by default instead of the top-level static/ directory (thanks, @amssljc, #499).

  • For a post that is the index page of a bundle, its images could not be displayed when the post content is displayed on other pages such as the home page (thanks, @andremrsantos #501, Fabio A. Cruz Sanchez https://stackoverflow.com/q/65097597/559676).

  • The _files/ and _cache/ folders are not correctly moved for index pages of leaf bundles when the filename of an index page contains a language code such as index.en.Rmd (thanks, @cderv, #500).

  • install_hugo() could not install the extended version of Hugo that was downloaded manually, e.g., blogdown::install_hugo('~/Downloads/hugo_extended_0.78.2_Linux-64bit.tar.gz') would fail (thanks, Stuart, https://stackoverflow.com/q/64962659/559676).

  • new_post(date = "") or new_post(date = NULL) failed to work. In both cases, it should create a post without the date field in the YAML metadata (thanks, Caleb Stevens, https://stackoverflow.com/q/65067164/559676).

  • new_site() no longer shows Hugo messages on Windows (#532).

  • new_site() can figure out the default branch name of a theme repo now, instead of assuming the master branch is the default (thanks, @c1au6i0, #541).

MINOR CHANGES

  • For new_site(to_yaml = TRUE), it will also convert config.toml to config.yaml.

  • The default value of the serve argument in new_site() was changed from TRUE to "ask" in an interactive R session, which means it will ask if users want to serve the site after creating it.

  • The default value for the format argument of new_site() was changed from toml to yaml, which means it will generate config.yaml instead of config.toml by default.

  • new_site() will create two sample scripts R/build.R and R/build2.R (they can be deleted if you don’t need them). See the help page ?blogdown::build_site for their meanings.

  • Autocomplete is supported for the names of important global options when typing inside options() in RStudio, e.g., when typing options(blogdown.au), RStudio will show the candidate blogdown.author.

  • read_toml() and toml2yaml() will try to preserve the original order of fields in the TOML data, instead of using the alphabetical order.

  • When clicking the “Build Website” button in RStudio, it will no longer open the index.html file in the generated site folder, but emit a message telling users that this folder needs to be served before the web pages can be correctly previewed (#522).

  • For Jekyll sites, the arguments --watch, --incremental, and --livereload are passed to jekyll serve by default. These arguments can be set via the global R option blogdown.jekyll.server.

  • The meta variable link-citations is set to true for the pandoc_args argument of blogdown::html_page(), so that links can be generated on citation items by default.

  • The internal function Rscript() was removed and it is publicly available in the xfun package now. If you need this function, please use xfun::Rscript() instead.

  • Removed internal functions is_windows(), is_osx(), and is_linux(). They are available in the xfun package now (note that is_osx() has become xfun::is_macos()).

CHANGES IN blogdown VERSION 0.21

CRAN release: 2020-10-11

NEW FEATURES

  • The Knit button in RStudio finally works with blogdown now. My apologies to those who have desperately clicked the Knit button or pressed Ctrl + Shift + K in vain over the years. I completely underestimated the power of your muscle memory.

  • Added a global R option blogdown.knit.on_save to control whether to knit R Markdown documents on save. By default, it is TRUE. If you do not want to knit a document as you save it, you may set options(blogdown.knit.on_save = FALSE) in your .Rprofile. If this option is not set initially, it will be set to FALSE after you click the Knit button in RStudio.

  • blogdown::build_site() no longer recompiles R Markdown files by default, because it may be expensive and often undesirable to compile Rmd files that have been compiled before. If you do want to recompile Rmd files, you may use blogdown::build_site(build_rmd = TRUE). See the help page ?blogdown::build_site for more information.

  • Added a helper function blogdown::bundle_site() to move post files into leaf bundles in a website, e.g., from content/foo/bar/hello-world.Rmd to content/foo/bar/hello-world/index.Rmd.

  • Exported the (previously internal) function blogdown::filter_md5sum function (#341). See its potential application on the help page ?blogdown::build_site.

  • Similarly, the function blogdown::filter_timestamp() has been exported and documented.

  • If a theme contains Hugo modules (e.g., the former hugo-academic theme), the modules will be resolved at the time when a theme is installed, which means users will not need to install Go or GIT to work with themes that contain Hugo modules.

  • Added a new function hugo_available() to check if Hugo with a minimal version is available.

  • Added functions read_toml() and write_toml() to read/write TOML data, and functions toml2yaml() and yaml2toml() to convert data between TOML and YAML. See their help pages for details.

  • Added the keep_md argument to blogdown::html_page() (thanks, @lazappi, #445).

MAJOR CHANGES

  • When creating a new site with blogdown::new_site(), the theme gcushen/hugo-academic is automatically redirected to wowchemy/starter-academic, because the original Github repo has moved and become a repo of Hugo modules.

  • The default value of the global option blogdown.new_bundle was changed from FALSE to TRUE if the site is built through Hugo >= v0.32. This means new posts will be created as leaf bundles, i.e., of the form path/post-filename/index.md instead of path/post-filename.md (the extension .md may also be .Rmd or .Rmarkdown). If you are not familiar with Hugo’s page bundles, please see the documentation at: https://gohugo.io/content-management/page-bundles/. Using page bundles makes it much easier to manage resources like images. Without page bundles, these resources have to be placed under the static/ directory, and cannot live together with posts under the content/ directory. If you do not like this change, you may still set options(blogdown.new_bundle = FALSE) in your .Rprofile. If you do like page bundles and want to convert old posts into bundles, the function blogdown::bundle_site() may be helpful.

  • For page bundles, the index_files/ and index_cache/ folders are no longer moved to the static/ directory (for other types of posts, these folders are still moved). Consequently, you should not ignore "_files$" in the ignoreFiles field in your config.toml or config.yaml any more.

  • When opening a blogdown project in RStudio, blogdown::serve_site() will be automatically called, so you will get the preview of the site immediately. If you do not like this behavior, you may set options(blogdown.serve_site.startup = FALSE) in your .Rprofile.

  • The global option blogdown.generator.server has been deprecated. Now blogdown::serve_site() always use the Hugo server (which corresponds to options(blogdown.generator.server = TRUE) in previous version of blogdown), instead of the server created via the servr package (which corresponds to the default options(blogdown.generator.server = FALSE) before). The Hugo server is much faster, and also supports navigating to the output web page of which you are currently editing the source document. Note that the option blogdown.hugo.server is still supported (for setting command-line arguments for hugo server), and its default value is c('-D', '-F', '--navigateToChanged'). Also note that using Hugo’s server means the website is not rendered to disk (i.e., it will not generate the public/ folder) by default but served directly from memory. If you need the public/ folder, you have to build the site explicitly via blogdown::build_site(), or if you use RStudio, press Ctrl + Shift + B or Cmd + Shift + B to build the website project (#495).

MINOR CHANGES

  • The command-line argument --navigateToChanged is passed to hugo server by default now if the Hugo version is not older than 0.25. If you start a Hugo server to serve and watch the site, it will automatically navigate to the page corresponding to the changed file.

  • Images tn.png and screenshot.png under the images/ directory of a theme will be deleted in blogdown::install_theme() because these are screenshots of a theme and don’t affect the theme’s function.

CHANGES IN blogdown VERSION 0.20

CRAN release: 2020-06-23

BUG FIXES

CHANGES IN blogdown VERSION 0.19

CRAN release: 2020-05-22

NEW FEATURES

  • 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).

BUG FIXES

  • 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).

CHANGES IN blogdown VERSION 0.18

CRAN release: 2020-03-04

NEW FEATURES

  • The “New Post” addin in RStudio uses the whoami package (if installed) to figure out the author name, in addition to using the global option 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).

CHANGES IN blogdown VERSION 0.17

CRAN release: 2019-11-13

CHANGES IN blogdown VERSION 0.16

CRAN release: 2019-10-01

MINOR CHANGES

  • Added tests for some utility functions (thanks, @novica, #405).

CHANGES IN blogdown VERSION 0.15

CRAN release: 2019-08-21

BUG FIXES

CHANGES IN blogdown VERSION 0.14

CRAN release: 2019-07-13

NEW FEATURES

  • 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).

CHANGES IN blogdown VERSION 0.13

CRAN release: 2019-06-11

NEW FEATURES

  • Added a global option 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).

CHANGES IN blogdown VERSION 0.12

CRAN release: 2019-05-01

MINOR CHANGES

  • When creating a post with a date in the future, a warning will be issued by default. To turn off this warning (if you are aware of the consequences of future dates), set options(blogdown.warn.future = FALSE) (thanks, @Chucheria on Twitter, #377).

CHANGES IN blogdown VERSION 0.11

CRAN release: 2019-03-11

NEW FEATURES

  • Added a global option 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).

MAJOR CHANGES

  • When previewing a blogdown website with Hugo on the RStudio Server, the Hugo configuration relativeURLs will be set to true automatically (thanks, @nwstephens, #124).

MINOR CHANGES

  • Added support to install the extended version of Hugo and enabled it as default via install_hugo(..., extended = TRUE) (thanks, @rgaiacs, #363).

CHANGES IN blogdown VERSION 0.10

CRAN release: 2019-01-09

NEW FEATURES

  • 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:::filter_timestamp, 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:::filter_md5sum) 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).

MINOR CHANGES

CHANGES IN blogdown VERSION 0.9

CRAN release: 2018-10-23

NEW FEATURES

  • Added an option in the “Update Metadata” addin to rename the post filename accordingly when the date is updated, e.g., when the date is changed from 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.

CHANGES IN blogdown VERSION 0.8

CRAN release: 2018-07-15

BUG FIXES

  • A bug was introduced when implementing #305: should append draft: yes to YAML only when options(blogdown.draft.output = TRUE) is set (thanks, @ConorIA, #312).

CHANGES IN blogdown VERSION 0.7

CRAN release: 2018-07-07

NEW FEATURES

  • 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).

BUG FIXES

CHANGES IN blogdown VERSION 0.6

CRAN release: 2018-04-18

NEW FEATURES

  • 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).

BUG FIXES

  • The 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).

MINOR CHANGES

  • The Github repo yihui/hugo-lithium-theme was renamed to yihui/hugo-lithium, and the default theme argument value was changed accordingly (thanks, @rorynolan, #291).

CHANGES IN blogdown VERSION 0.5

CRAN release: 2018-01-24

BUG FIXES

  • The bug #233 still exists on Windows (thanks, Sheng Luan).

CHANGES IN blogdown VERSION 0.4

CRAN release: 2017-12-12

BUG FIXES

  • 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).
