Lua Env Extension For Quarto

lua-env is an extension for Quarto to provide access to LUA objects as metadata.

Installing

quarto add mcanouil/quarto-lua-env

This will install the extension under the _extensions subdirectory. If you're using version control, you will want to check in this directory.

Using

Add the following to your YAML header:

filters:
  - lua-env

This will give you access to the quarto and several Pandoc LUA internal objects using any of the below shortcodes:

{{< lua-env quarto.doc.input_file >}}

{{< meta lua-env.quarto.doc.input_file >}}

LUA objects currently available as metadata:

lua-env:
  quarto: "quarto"
  pandoc:
    PANDOC_STATE: "PANDOC_STATE"
    FORMAT: "FORMAT"
    PANDOC_READER_OPTIONS: "PANDOC_READER_OPTIONS"

    PANDOC_VERSION: "PANDOC_VERSION"
