Rendering quarto-web locally

This section discusses how to contribute to the documentation by rendering a document locally.

Quarto-web uses a frozen state of computation

This Quarto project uses freeze: true, meaning it will never run computation engines during a project render. No Knitr or Jupyter configuration is needed to build the whole website. The _freeze folder is tracked on the git repo for this purpose. (See about freeze for a reminder of how this works).

What is the impact if you modify (or add) a document:

Rendering the whole website

When you render quarto-web, you should use the current Pre-release of Quarto.

To render the whole website locally, you can use the following command:

# Update freeze state if needed
quarto render /docs/path/to/modified-or-added-document.qmd
# Render the whole website using freeze state for all the other docs
quarto render

Installing and managing computation environment

To manage computational dependencies this project uses

R environment for Knitr engine

This project uses R 4.3.2 and renv to manage its R dependencies. To install the R environment, you can use the following command at the project root:

Rscript -e "renv::restore()"

The project library will be located under the renv folder.

You don't need to worry about the R environment when you are working on this project. renv sets up .Rprofile to activate the project library when R is ran from the project's root. Just run your R code as usual, and renv will be activated automatically, meaning R will correctly use the project's library.

If you are adding a new document that may use a new package, follow these steps:

Note: Python dependencies are not tracked through renv but are tracked with pipenv. See below

Python environment for Jupyter engine and Knitr through reticulate

This project uses pipenv (https://pipenv.pypa.io/zh-cn/stable/index.html) to handle the Python dependencies. pipenv takes care of managing dependencies and virtual environments for you.

To install the Python environment, you can use the following command at the project root:

pipenv sync

If you are using pyenv to manage your python installation, pipenv will ask you to install a newer version of python if the one currently used does not match the one from Pipfile.lock. Though, the exact match of version isn't required and this should not be a problem to not upgrade your python installation.

The virtual environment will be located in the project directory under .venv (following the configuration of pipenv set in the .env file).

When in the root of the project, you can run pipenv shell to activate the virtual environment associated with the project. Any quarto command should then use the correct python environment. You can also run pipenv run quarto ... to run the quarto command in the virtual environment without activating it.

Inside VSCODE, The Python extension should find the same Python version (e.g. Python > Select Interpreter) which Quarto Preview uses. As this extension integrates also in the terminal, it should use the same Python version in the terminal as well without needing to use pipenv shell or pipenv run.

If you are adding a new document that may use a new package, follow these steps:

Documents running python with the Knitr engine will go through reticulate. reticulate will use the python version defined with pipenv when a PipFile is present. So, it will use the Python version from .venv --- no specific configuration is needed as reticulate's python discovery mechanism will find it.

Reference pages are automatically generated

The tablular data on options listed in the Reference section are generated automatically by running:

quarto run tools/reference.ts

This builds the .json files in docs/references based on the Quarto CLI schema. The script assumes you have quarto-cli/ at the same level in your directory structure as quarto-web/.
