Path to include code file differs depending on output format e.g. HTML or PDF

[MichelDSchmid]

I figures out some more details and according to your request from here quarto-dev/quarto-cli#4340 (comment) I will open this issue:

To get code highlighting in HTML AND PDF I have to include the code file with different path:
`
::: {.content-visible when-format="html"}
```{.c include="../code/test.c"}
```
:::

::: {.content-visible when-format="pdf"}
```{.c include="./code/test.c"}
```
:::
`
On this way I get the code highlighting in html and pdf.
I attached the complete test project.

Quarto Version: 1.2.334 with installed include-code-files extension.

Thank you very much for your help
regards

I found the same issue when rendering HTML and MS.
I have to hard code the absolute path in include-code-filters.lua in order to make it work in both formats:

local function transclude (cb)
  if cb.attributes.include then
    local path = "C:/Users/dr/Desktop/mybook/code"..cb.attributes.include
    local fh, err = io.open(path)

Can we get the project root path? I did not find any kind of api or environment variables.

Can we get the project root path? I did not find any kind of api or environment variables.

I just searched for that myself, and as far as I can tell, this is not exposed by Quarto.

There is quarto.project.directory

This is still something we need to document

• Document all public functions from quarto Lua API quarto-dev/quarto-cli#4499

It was only mentioned in Changelog for 1.2
https://github.com/quarto-dev/quarto-cli/blob/4b0bbb9709044ff26deb3833a06aa99dc69836f2/news/changelog-1.2.md?plain=1#L31-L38

You could use that to tweak the lua extension code

    local fh = io.open(pandoc.path.join({quarto.project.directory, cb.attributes.include}))

This will work only in Project. We need to probably go to the root issue here in Quarto CLI:

Lua code working directory (pandoc.system.get_working_directory()) is not the same for HTML and PDF rendering...
This is unexpected to me. 🤔
