Share on a GitHub website
In fusen: Build a Package from Rmarkdown Files

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)

library(fusen)

You write R scripts and you would like to share them with other users, in a sustainable and maintainable way. You already know how to write a notebook (Rmarkdown or Quarto) and share its HTML output, but you do not like to present the outputs along with how to use the functions in the same web page.

If you plan on sharing your package on GitHub, fusen::init_share_on_github() creates all necessary files in your project and send them on your GitHub account to create the website of the package documentation. Then, you can focus on the content.
Follow the steps below and you'll see your public website documentation in no time!

Initiate your package and share it on GitHub

Create a new project with {fusen} using git

#| echo: false
#| eval: false
path_project <- "your/path/where/to/start/your/project/project_name"
fusen::create_fusen(path = path_project, template = "minimal", with_git = TRUE, open = TRUE)

Follow the "dev/0-dev_history.Rmd" to describe your project
At least, you will have to fill the fusen::fill_description() function with your identity as below

#| eval: false
# Describe your project
fusen::fill_description(
  pkg = here::here(),
  fields = list(
    Title = "Share Your Project Following Good Development Practices From a Rmarkdown File",
    Description = "Use Rmarkdown First method. Strengthen your work with documentation and tests. Everything can be set from a Rmarkdown file in your project.",
    `Authors@R` = c(
      person("John", "Doe", email = "john@email.me", role = c("aut", "cre"), comment = c(ORCID = "0000-0000-0000-0000"))
    )
  )
)
# Define License with use_*_license()
usethis::use_mit_license("John Doe")

Open the "dev/flat_full.Rmd"
This is the skeleton to follow if you want a properly documented and tested work
- Write what the code is supposed to do in plain markdown
- Separate the function from the example and test chunks
- Create new sections below in your flat template with the Addin > add {fusen} chunk
Then inflate() the flat template to build the proper structure of the project
- Sections will be transferred in the correct places to get a proper package
- A set of checks will be run to verify that your work is properly documented and tested

#| eval: false
fusen::inflate(flat_file = "dev/flat_full.Rmd", vignette_name = "Get started")

Share your work on a website using GitHub
You may need to run usethis::create_github_token(), then gitcreds::gitcreds_set() before, if you do not have a registered GitHub token yet.
You will be asked multiple times if you want to commit, you can say "yes" each time.

#' \dontrun{
#' # This modifies the current directory and send it on GitHub
init_share_on_github()
#' }

In a few minutes, you'll be able to see and share your project website.
You won't have to run this command line again. Each time you push new commits to the main branch on GitHub, your website will be updated thanks to GitHub Actions.

What happens behind the scene ?

init_share_on_github() runs multiple steps to be able to share a proper package on GitHub:

Start versionning with git if not already
Connect to your GitHub account
Create a minimal DESCRIPTION file if missing
You will have to update its content with your information after deployment
Add NEWS file to present modifications of your releases
Add README.Rmd and knit it to README.md to quickly present the aim and the use of your package
Init continuous integration (CI)
Check the package on Linux, Windows and MacOS
Calculate code coverage
Init continuous deployment (CD) of the {pkgdown} website documentation
Commit and push to GitHub
List remaining manual steps to make the website public
