hugodown is an experimental package that aims to facilitate the use of [RMarkdown](http://rmarkdown.rstudio.com/) and [hugo](http://gohugo.io/) together. It's similar to [blogdown](https://bookdown.org/yihui/blogdown/), but is focussed purely on Hugo websites, and enforces a stricter partitioning of roles: hugodown is responsible for transforming `.Rmd` to `.md`, and hugo is responsible for transforming `.md` to `.html`.



## Compared to blogdown



* It only re-runs your R code when you explicitly ask for it (by knitting the 

  post). This makes hugodown considerably easier to use for long-running blogs 

  and blogs with multiple contributors. 

  

* Local previews are pinned to a specific version of hugo. This makes it easier

  to work with multiple blogs, and protects your from hugo <-> theme 

  version incompatibilities.

  

* It provides support for getting started with a limited number of themes,

  automatically making needed tweaks to ensure that html widgets, syntax 

  highlighting, and math display work out of the box.



* It does not currently support within page cross-references for figures, 

  tables, and equations.



* It is more opinionated about hugo configuration; see `vignette("config")` 

  for details.

  

* It is designed around a single Rmarkdown format, `.Rmd`.



## Installation



hugodown isn't available from CRAN yet (and might never be), but you can install the development version from GitHub with:



``` r

devtools::install_github("r-lib/hugodown")

```



## Usage



The key to using hugodown is to put `output: hugodown::md_document()` in the YAML metadata of your `.Rmd` files. Then knitting the file will generate a `.md` file designed to work well with hugo. The rest of hugodown just makes your life a little easier:



* `hugo_start()` will automatically start a hugo server in the background,

  automatically previewing your site as you update it.



* `use_post()` will create a new post (filling in default content from

  the hugo [archetype](https://gohugo.io/content-management/archetypes/)).

  

* To knit an `.Rmd` post, you can use the Knit button to knit to the correct output format. You can also use the keyboard shortcut `Cmd+Shift+K` (Mac) or `Ctrl+Shift+K` (Windows/Linux).

  

* `site_outdated()` lists all `.Rmd` files that need to be re-rendered 

  (i.e. they have changed since the last time their `.md` was rendered).

  

With hugodown, knitting an individual post and building the site are two separate processes. A good workflow when working with an existing Hugo site in RStudio is to open the site's `.Rproj` file, use `hugo_start()`, then add or edit your posts. Because the hugo server will only add `.Rmd` content to your site preview after knitting, you'll need to use the keyboard shortcut to knit first.



### Citations



To use citations in a blog post, just provide a `bibliography` in the YAML metadata. If you want to use footnotes for citations (a style that generally works well in blogs), you'll need to find a footnote style CSL file (e.g. [`chicago-fullnote-bibliography.csl`][footnote-csl], and use the following YAML header.



```yaml

bibliography: refs.bib

suppress-bibliography: true

csl: chicago-fullnote-bibliography.csl

```



## Converting from blogdown



* Make sure your post archetype has extension `.Rmd` and includes

  `output: hugodown::md_document` in the YAML. The post archetype

  should typically be `archetypes/blog/index.Rmd`.

  

* Delete `index.Rmd` from the root of your site.



* Ensure that hugo is configured as described in `vignette("config")`.
