This repo contains a collection of reusable workflows found helpful for R packages. In addition, {ghactions4r} contains helper functions for setting up the workflows in a separate R package GitHub repository.

Rather than having to maintain your own GitHub actions files (as you would need to with actions set up with usethis::use_github_action()), using a {ghactions4r} use_* function sets up a github actions file to directly call actions that exist and are maintained in the {ghactions4r} repository (in the workflows folder). This means all maintenance happens within the {ghactions4r} repository rather than in your repository!

First, install the {ghactions4r} R package.

Using R universe:

install.packages("ghactions4r", 
repos = c("https://noaa-fisheries-integrated-toolbox.r-universe.dev", 
          "https://cran.r-project.org"))

or remotes::install_github():

install.packages("remotes")
remotes::install_github("nmfs-ost/ghactions4r")

Users who are part of the NOAA Fisheries GitHub Enterprise may run into an error installing the package. You may need to authorize your token or use a development version of remotes::install_github(). Still need help? Open an issue on this repository.

use_*() functions in the {ghactions4r} package work like use_*() functions in the usethis package.

Open the cloned repository of an R package and run the function of choice. These functions set up the files needed to use the reproducible workflows in {ghactions4r}. Below are a list of the basic functions, for complete options, see the pkgdown reference documentation.

• To run R CMD check using Linux (R release and R development), Mac (R release), and Windows (R release):

ghactions4r::use_r_cmd_check()

• To calculate code coverage using covr and octocov (so that all code coverage calculations data remains in your GitHub repository) and create summaries on pull request and on pushes to main:

ghactions4r::use_calc_cov_summaries()

• Note that a previous workflow to calculate code coverage and push it to codecov.io is deprecated

• To create a badge (stored on a branch in the repo called badges) for coverage that can be added to your R package's readme:

ghactions4r::use_create_cov_badge()

• To update documentation, DESCRIPTION file, and code styling for an R package (with the option of running ghactions4r::rm_dollar_sign()):

ghactions4r::use_doc_and_style_r(use_rm_dollar_sign = FALSE)

• To automatically update pkgdown that has already been set up:

ghactions4r::use_update_pkgdown()

• To check that a pkgdown site builds:

ghactions4r::use_build_pkgdown()

• To spell check an R package:

ghactions4r::use_spell_check()

Commit and push the files generated up to github, making the github actions available for the repository of the R package.

The templates these functions generate can also be viewed for reference.

Check that GitHub Actions has been given the right GITHUB_TOKEN permissions. GitHub Actions will have read-only permissions by default, rather than read and write permissions. For many workflows in this repository, read and write permissions are necessary. To modify the permissions, follow these GitHub Documentation instructions.

If still running into failing actions, please submit an issue or email kathryn.doering@noaa.gov. Bugs are always possible, as this repository is still experimental. Reporting issues will make {ghactions4r} better for all users!

r-lib/actions Includes basic actions for R as well as example workflows. In fact, many of the reusable workflows in {ghactions4r} are based on these examples. Many of these can be set up through usethis' GitHub Actions functions.

{ghactions4r} uses the NOAA FIT Code of Conduct.

Contributions are welcome! Contributions can be code, but are not just code, but also includes things like:

• Reporting errors or bugs
• Suggesting enhancements
• Correcting or adding documentation (including editing the readme)
• Answering questions on the discussions page

Additional details are available in the NOAA FIT Contributing Guide.

• Make sure the workflow is in scope by opening an issue to ask.
• Create a feature branch or fork to do your work.
• Create the reusable workflow in .github/workflows. For consistency with other workflows, uses dashes (-) between words in the file name and use the extension .yml (not .yaml). Do NOT start the file name with call-.
• Create the template workflow for users to use in inst/templates. Name it the same as the reusable workflow, but with call- in front.
• Add a usethis style function to help the user add the workflow by adding the new function to R/use_r_workflows.R. Follow the style of the workflows already there.
• Add a test (or tests) in tests/testthat/test-use_r_workflow.R. Add a new test to the end of the file and follow the style of the existing tests in the script.
• Add to the "How do I use these workflows in my R package?" section of the readme, showing how to use the usethis style r function.
• Open a pull request to main when work is ready for review!
