Package 'altdoc'

Description

Preview the documentation in a webpage or in viewer

Usage

preview_docs(path = ".")

Arguments

Value

No value returned. If RStudio is used, it shows a site preview in Viewer. To preview the site in a browser or in another text editor (ex: VS Code), see the vignette on the altdoc website.

Examples

if (interactive()) {

  preview_docs()

}

# This is an example to illustrate that code-generated images are properly
# displayed. See the `altdoc` website for a rendered version.

Description

Render and update the function reference manual, vignettes, README, NEWS, CHANGELOG, LICENSE, and CODE_OF_CONDUCT sections, if they exist. This function overwrites the content of the 'docs/' folder. See details below.

Usage

render_docs(path = ".", verbose = FALSE, parallel = FALSE, freeze = FALSE, ...)

Arguments

Details

This function searches the root directory and the ⁠inst/⁠ directory for specific filenames, renders/converts/copies them to the ⁠docs/⁠ directory. The order of priority for each file is established as follows:

• docs/README.md

  • README.md, README.qmd, README.Rmd

• docs/NEWS.md

  • NEWS.md, NEWS.txt, NEWS, NEWS.Rd

  • Note: Where possible, Github contributors and issues are linked automatically.

• docs/CHANGELOG.md

  • CHANGELOG.md, CHANGELOG.txt, CHANGELOG

• docs/CODE_OF_CONDUCT.md

  • CODE_OF_CONDUCT.md, CODE_OF_CONDUCT.txt, CODE_OF_CONDUCT

• docs/LICENSE.md

  • LICENSE.md, LICENSE.txt, LICENSE

Altdoc variables

The settings files in the ⁠altdoc/⁠ directory can include ⁠$ALTDOC⁠ variables which are replaced automatically by altdoc when calling render_docs():

• ⁠$ALTDOC_PACKAGE_NAME⁠: Name of the package from DESCRIPTION.

• ⁠$ALTDOC_PACKAGE_VERSION⁠: Version number of the package from DESCRIPTION

• ⁠$ALTDOC_PACKAGE_URL⁠: First URL listed in the DESCRIPTION file of the package.

• ⁠$ALTDOC_PACKAGE_URL_GITHUB⁠: First URL that contains "github.com" from the URLs listed in the DESCRIPTION file of the package. If no such URL is found, lines containing this variable are removed from the settings file.

• ⁠$ALTDOC_MAN_BLOCK⁠: Nested list of links to the individual help pages for each exported function of the package. The format of this block depends on the documentation generator.

• ⁠$ALTDOC_VIGNETTE_BLOCK⁠: Nested list of links to the vignettes. The format of this block depends on the documentation generator.

• ⁠$ALTDOC_VERSION⁠: Version number of the altdoc package.

Also note that you can store images and static files in the ⁠altdoc/⁠ directory. All the files in this folder are copied to ⁠docs/⁠ and made available in the root of the website, so you can link to them easily.

Altdoc preambles

When you call render_docs(), altdoc will automatically paste the content of one of these three files to the top of a document:

• altdoc/preamble_vignettes_qmd.yml

• altdoc/preamble_vignettes_rmd.yml

• altdoc/preamble_man_qmd.yml

The README file uses the vignette preamble.

To preempt this behavior, add your own preamble to the README file or to a vignette.

Freeze

When working on a package, running render_docs() to preview changes can be a time-consuming road block. The argument freeze = TRUE tries to improve the experience by preventing rerendering of files that have not changed since the last time render_docs() was ran. Note that changes to package internals will not cause a rerender, so rerendering the entire docs can still be necessary.

For non-Quarto formats, this is done by creating a freeze.rds file in ⁠altdoc/⁠ that is able to determine which documentation files have changed.

For the Quarto format, we rely on the Quarto freeze feature. Freezing a document needs to be set either at a project or per-file level. Freezing a document needs to be set either at a project or per-file level. To do so, add to either quarto_website.yml or the frontmatter of a file:

execute:
  freeze: auto

Auto-link for Quarto websites

When the code-link format setting is true in altdoc/quarto_website.yml and the downlit package is installed, altdoc will use the downlit package to replace the function names on the package website by links to web-based package documentation. This works for base R libraries and any package published on CRAN.

To allow internal links to functions documented by altdoc, we need to include links to correct URLs in the altdoc/pkgdown.yml file. By default, this file is populated with links to the first URL in the DESCRIPTION.

Importantly, downlit requires the pkgdown.yml file to be live on the website to create links. This means that links will generally not be updated when making purely local changes. Also, links may not be updated the first time an altdoc website is published to the web.

Examples

if (interactive()) {

  render_docs()

  # parallel rendering
  library(future)
  plan(multicore)
  render_docs(parallel = TRUE)

}

Description

Creates a subdirectory called ⁠altdoc/⁠ in the package root directory to store the settings files used to by one of the documentation generator utilities (docsify, docute, mkdocs, or quarto_website). The files in this folder are never altered automatically by altdoc unless the user explicitly calls overwrite=TRUE. They can thus be edited manually to customize the sidebar and website.

Usage

setup_docs(tool, path = ".", overwrite = FALSE)

Arguments

Package structure

altdoc makes assumptions about your package structure:

• The homepage of the website is stored in README.qmd, README.Rmd, or README.md.

• ⁠vignettes/⁠ stores the vignettes in .md, .Rmd or .qmd format.

• ⁠docs/⁠ stores the rendered website. This folder is overwritten every time a user calls render_docs(), so you should not edit it manually.

• ⁠altdoc/⁠ stores the settings files created by setup_docs(). These files are never modified automatically after initialization, so you can edit them manually to customize the settings of your documentation and website. All the files stored in ⁠altdoc/⁠ are copied to ⁠docs/⁠ and made available as static files in the root of the website.

• These files are imported automatically: NEWS.md, CHANGELOG.md, CODE_OF_CONDUCT.md, LICENSE.md, LICENCE.md.

Altdoc variables

The settings files in the ⁠altdoc/⁠ directory can include ⁠$ALTDOC⁠ variables which are replaced automatically by altdoc when calling render_docs():

• ⁠$ALTDOC_PACKAGE_NAME⁠: Name of the package from DESCRIPTION.

• ⁠$ALTDOC_PACKAGE_VERSION⁠: Version number of the package from DESCRIPTION

• ⁠$ALTDOC_PACKAGE_URL⁠: First URL listed in the DESCRIPTION file of the package.

• ⁠$ALTDOC_PACKAGE_URL_GITHUB⁠: First URL that contains "github.com" from the URLs listed in the DESCRIPTION file of the package. If no such URL is found, lines containing this variable are removed from the settings file.

• ⁠$ALTDOC_MAN_BLOCK⁠: Nested list of links to the individual help pages for each exported function of the package. The format of this block depends on the documentation generator.

• ⁠$ALTDOC_VIGNETTE_BLOCK⁠: Nested list of links to the vignettes. The format of this block depends on the documentation generator.

• ⁠$ALTDOC_VERSION⁠: Version number of the altdoc package.

Also note that you can store images and static files in the ⁠altdoc/⁠ directory. All the files in this folder are copied to ⁠docs/⁠ and made available in the root of the website, so you can link to them easily.

Altdoc preambles

When you call render_docs(), altdoc will automatically paste the content of one of these three files to the top of a document:

• altdoc/preamble_vignettes_qmd.yml

• altdoc/preamble_vignettes_rmd.yml

• altdoc/preamble_man_qmd.yml

The README file uses the vignette preamble.

To preempt this behavior, add your own preamble to the README file or to a vignette.

Examples

if (interactive()) {

  # Create docute documentation
  setup_docs(tool = "docute")

  # Create docsify documentation
  setup_docs(tool = "docsify")

  # Create mkdocs documentation
  setup_docs(tool = "mkdocs")

  # Create quarto website documentation
  setup_docs(tool = "quarto_website")
}

Description

This function creates a Github Actions workflow in ".github/workflows/altdoc.yaml". This workflow will automatically render the website using the setup specified in the folder "altdoc" and will push the output to the branch "gh-pages".

Usage

setup_github_actions(path = ".")

Arguments

Value

No value returned. Creates the file ".github/workflows/altdoc.yaml"

Examples

if (interactive()) {
  setup_github_actions()
}
