RcppSMCdocs

Documentation for RcppSMC.

Types of documentation

Two types of documentation are available:

1. Good old doxygen:

   • create ./build and cmake .. followed by make docs
   • produces html files in the directory ./build/docs_doxygen/html
   • view the documentation via ./build/docs_doxygen/html/index.html

2. Using Sphinx (modern look, facilitates readability, but less detailed API documentation)

   • use make html inside ./docs_sphinx
   • output is stored in ./docs_sphinx/html
   • view the documentation via ./docs_sphinx/html/index.html

Workflow to update, alter or re-generate documentation

Making additions if underlying code changes

1. Copy new code into ./include or ./src
2. git add ., git commit and git push, which triggers automatic deployment
3. Github actions automatically deploys the page

Switching between doxygen and Sphinx-read-the-docs-styles

The directory ./.github/workflows/docs.yml contains the config for this. The following part is relevant to change from Sphinx-style to doxygen-style web documentation:

...
- name: Build docs
run: cd docs_sphinx # cd build
&& make html # && cmake ..
&& cd _build/html # && make docs
&& touch .nojekyll # delete this statement if doxygen is used
...
FOLDER: docs_sphinx/_build/html # build/docs_doxygen/html- name: Deploy
uses: JamesIves/github-pages-deploy-action@v4.3.3
with:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
BRANCH: gh-pages # The branch the action should deploy to.
FOLDER: docs_sphinx/_build/html # FOLDER: build/docs_doxygen/html

1. In the above snippet, the Sphinx style is run. To change to doxygen, switch statements to:

   • run: cd build (run: cd docs_sphinx before)
   • && cmake .. (&& make html before)
   • && make docs (&& cd _build/html before)
   • delete && touch .nojekyll
   • FOLDER: build/docs_doxygen/html (FOLDER: docs_sphinx/_build/html before)

2. git add ., git commit and git push which triggers automatic deployment
