Arguments

...	Arguments to be passed to system2('hugo', ...), e.g. new_content(path) is basically hugo_cmd(c('new', path)) (i.e. run the command hugo new path).
version	A version number.
exact	If FALSE, check if the current Hugo version is equal to or higher than the specified version. If TRUE, check if the exact version is available.
local	Whether to build the site for local preview (if TRUE, all drafts and future posts will also be built).
args	A character vector of command-line arguments to be passed to hugo, e.g., c("--minify", "--quiet").
baseURL, relativeURLs	Custom values of baseURL and relativeURLs to override Hugo's default and the settings in the site's config file.
dir	The directory of the new site.
force	Whether to create the site in a directory even if it is not empty. By default, force = TRUE when the directory only contains hidden, RStudio project (‘*.Rproj’), ‘LICENSE’, and/or ‘README’ files.
install_hugo	Whether to install Hugo automatically if it is not found.
format	The format of the configuration file, e.g., 'yaml' or 'toml' (the value TRUE will be treated as 'yaml', and FALSE means 'toml'). Note that the frontmatter of the new (R) Markdown file created by new_content() always uses YAML instead of TOML or JSON.
sample	Whether to add sample content. Hugo creates an empty site by default, but this function adds sample content by default.
theme	A Hugo theme on Github (a character string of the form user/repo, and you can optionally specify a GIT branch or tag name after @, i.e. theme can be of the form user/repo@branch). You can also specify a full URL to the zip file or tarball of the theme. If theme = NA, no themes will be installed, and you have to manually install a theme.
hostname	Where to find the theme. Defaults to github.com; specify if you wish to use an instance of GitHub Enterprise. You can also specify the full URL of the zip file or tarball in theme, in which case this argument is ignored.
theme_example	Whether to copy the example in the ‘exampleSite’ directory if it exists in the theme. Not all themes provide example sites.
empty_dirs	Whether to keep the empty directories generated by Hugo.
to_yaml	Whether to convert the metadata of all posts to YAML.
netlify	Whether to create a Netlify config file ‘netlify.toml’.
.Rprofile	Whether to create a ‘.Rprofile’ file. If TRUE, a sample ‘.Rprofile’ will be created. It contains some global options, such as options(blogdown.hugo.version), which makes sure you will use a specific version of Hugo for this site in the future.
serve	Whether to start a local server to serve the site. By default, this function will ask you in an interactive R session if you want to serve the site.
path	The path to the new file under the ‘content’ directory.
kind	The content type to create, i.e., the Hugo archetype. If the archetype is a page bundle archetype, it should end with a slash, e.g., post/.
open	Whether to open the new file after creating it. By default, it is opened in an interactive R session.
title	The title of the post.
author	The author of the post.
categories	A character vector of category names.
tags	A character vector of tag names.
date	The date of the post.
time	Whether to include the time of the day in the date field of the post. If TRUE, the date will be of the format ‘⁠%Y-%m-%dT%H:%M:%S%z⁠’ (e.g., ‘⁠2001-02-03T04:05:06-0700⁠’). Alternatively, it can take a character string to be appended to the date. It can be important and helpful to include the time in the date of a post. For example, if your website is built on a server (such as Netlify or Vercel) and your local timezone is ahead of UTC, your local date may be a future date on the server, and Hugo will not build future posts by default (unless you use the -F flag).
file	The filename of the post. By default, the filename will be automatically generated from the title by replacing non-alphanumeric characters with dashes, e.g. title = 'Hello World' may create a file ‘content/post/2016-12-28-hello-world.md’. The date of the form YYYY-mm-dd will be prepended if the filename does not start with a date.
slug	The slug of the post. By default (NULL), the slug is generated from the filename by removing the date and filename extension, e.g., if file = 'post/2020-07-23-hi-there.md', slug will be hi-there. Set slug = '' if you do not want it.
title_case	A function to convert the title to title case. If TRUE, the function is tools::toTitleCase()). This argument is not limited to title case conversion. You can provide an arbitrary R function to convert the title.
subdir	If specified (not NULL), the post will be generated under a subdirectory under ‘content/’. It can be a nested subdirectory like ‘post/joe/’.
ext	The filename extension (e.g., ‘.md’, ‘.Rmd’, or ‘.Rmarkdown’). Ignored if file has been specified.
to	A format to convert to.
unsafe	Whether to enable unsafe operations, such as overwriting Markdown source documents. If you have backed up the website, or the website is under version control, you may try unsafe = TRUE.
host, port	The host IP address and port; see servr::server_config().

Functions

• hugo_cmd(): Run an arbitrary Hugo command.

• hugo_version(): Return the version number of Hugo if possible, which is extracted from the output of hugo_cmd('version').

• hugo_available(): Check if Hugo of a certain version (or above if exact = FALSE) is available.

• hugo_build(): Build a plain Hugo website. Note that the function build_site() first compiles Rmd files, and then calls Hugo via hugo_build() to build the site.

• new_site(): Create a new site (skeleton) via hugo new site. The directory of the new site should be empty,

• new_content(): Create a new (R) Markdown file via hugo new (e.g. a post or a page).

• new_post(): A wrapper function to create a new post under the ‘content/post/’ directory via new_content(). If your post will use R code chunks, you can set ext = '.Rmd' or the global option options(blogdown.ext = '.Rmd') in your ‘~/.Rprofile’. Similarly, you can set options(blogdown.author = 'Your Name') so that the author field is automatically filled out when creating a new post.

• hugo_convert(): A wrapper function to convert source content to different formats via hugo convert.

• hugo_server(): Start a Hugo server.
