tidymodels.org

This repo is the source of https://www.tidymodels.org, and this readme tells you how it all works.

• If you spot any small problems with the website, please feel empowered to fix them directly with a PR.

• If you see any larger problems, an issue is probably better: that way we can discuss the problem before you commit any time to it.

Requirements to preview the site locally

R packages

When updating the site, the goal is to use the most recent CRAN versions of the modeling/data analysis packages.

1. Get a local copy of the website source.

   • Users of devtools/usethis can do:

     usethis::create_from_github(“tidymodels/tidymodels.org”)

     Note that usethis::create_from_github() works best when it can find a GitHub personal access token and usethis (git2r, really) is configured correctly for your preferred transport protocol (SSH vs HTTPS). Setup advice.
   • Otherwise, use your favorite method to fork and clone or download the repo as a ZIP file and unpack.

2. Start R in your new tidymodels.org/ directory.

3. To install the required packages, run the code within

   static/code/installs.R
   

   This file will also install the keras python libraries and environments.

4. Restart R.

5. You should now be able to render the site in all the usual ways for blogdown, such as blogdown::serve_site() or Addins > Serve Site.

Hugo

In addition to R packages, you'll need to make sure that you are using the same version of Hugo that we use to build the site. If you are not familiar with Hugo, it is the static site generator that we are using via the R blogdown package. To check your local version of Hugo, you can do:

# install.packages("blogdown") # if not using renv
blogdown::hugo_version()

Then check that against the version of Hugo we use to build our site.

If you have an older version of Hugo than what we use, you can update with:

blogdown::update_hugo()

Once you are up-to-date, you can build the site locally using:

blogdown::serve_site()

or Addins > Serve Site in the RStudio IDE.

This will open a preview of the site in your web browser, and it will automatically update whenever you modify one of the input files. For .Rmarkdown and .Rmd files, this will generate either a .markdown or an .html file. These rendered files need to be commited and pushed to GitHub to be published on the site.

Structure

The source of the website is a collection of .md, .Rmarkdown, and .Rmd files stored in content/, which are rendered for the site with blogdown.

• content/packages/index.md: this is a top-level page on the site rendered from a single .md file. If you only edit this page, you do not have to use blogdown::serve_site() locally to render.

• content/start/: these files make up a 5-part tutorial series to help users get started with tidymodels. Each article is an .Rmarkdown file as a page bundle, meaning that each article is in its own folder along with accompanying images, data, and rendered figures. If you edit a tutorial, please run blogdown::serve_site() locally to render the .markdown file, and be sure to commit the rendered file to the repo. No *.Rmd or *.html files should be committed in this directory. If you generate an *.html file locally during development, delete it once it's no longer useful to you. Keep it out of this repo. Also please make sure if you edit a file in this section that nothing is added to the static/ folder- all accompanying files should be in the article page bundle.

• content/learn/: these files make up the articles presented in the learn section. This section is nested, meaning that inside this section, there are actually 4 subsections: models, statistics, work, develop. Each article is an .Rmarkdown file. If you edit or add an article, please run blogdown::serve_site() locally to render the .markdown file, and be sure to commit the rendered file to the repo.

  When you do that, any new articles added will show up on the main learn/ listing page automatically. By default, a maximum of 5 articles per subsection will show up in this list; use weights in the individual article YAML files to decide which 5 and their order. All articles with weights > 5 will show up when you click “See all” for that subsection. No *.Rmd or *.html files should be committed to this directory. If you generate an *.html file locally during development, delete it once it's no longer useful to you. Keep it out of this repo. Also please make sure if you edit a file in this section that nothing is added to the static/ folder- all accompanying files should be in the article page bundle.

• content/help/index.md: this is a top-level page on the site rendered from a single .md file. If you only edit this page, you do not have to use blogdown::serve_site() locally to render.

• content/contribute/index.md: this is a top-level page on the site rendered from a single .md file. If you only edit this page, you do not have to use blogdown::serve_site() locally to render.

• content/books/: these files make up the books page, linked from resource stickies. To add a new book, create a new folder with a new .markdown file inside named index.md. An image file of the cover should be added in the same folder, named cover.*.

• content/find/: these files make up the find page, linked from the top navbar and resource stickies. Each of these pages is an .Rmd file. If you edit a page, please run blogdown::serve_site() locally to render the .html file, and be sure to commit the rendered file to the repo. Also please make sure if you edit a file in this section that nothing is added to the static/ folder- all accompanying files should be in the article page bundle.

Troubleshooting

If blogdown attempts to re-render posts (potentially on a massive scale), you need to make all the derived files look more recently modified than their respective source files. This affects (.Rmarkdown, .markdown) and (.Rmd, .html) file pairs. Do something like this:

library(fs)

md <- dir_ls("content", recurse = TRUE, glob = "*.markdown")
file_touch(md)

html <- dir_ls("content", recurse = TRUE, glob = "*.html")
file_touch(html)

For other problems, consider that you need to update blogdown or to run blogdown::update_hugo() (perhaps in an R session launched with sudo).

Also, if you accidentally or intentionally knit or preview the content using another method than blogdown::serve_site() (e.g. click the Preview button in RStudio for .[R]md), make sure you don't commit an .html file from an .md file.
