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().
