Custom format not found in ignored subdir

[andrewpbray]

Description

I use custom formats widely in a website and in general they render just fine with all of the extensions installed via quarto add at the root of the project. Today I tried ignoring one of the subdirectories and suddenly the enclosed qmds were not able to find the extension on render.

I've created a minimal reprex repo that demonstrates the issue:

https://github.com/andrewpbray/ignored-extension

which is just the boilerplate website with quarto add mcanouil/quarto-letter added as as well as _ignored/custom-doc.qmd, which uses format: letter-pdf. It renders fine if the file is named ignored/custom-doc.qmd but as is it throws:

ERROR: Unable to read the extension 'letter'.
Please ensure that you provided the correct id and that the extension is installed.

If you move the file to the root of the project it also renders fine.

Any idea what's up?

How exactly did you get the error? quarto render _ignorable/custom-doc.qmd?

[mcanouil]

I just cloned the repository. It appears that ignored documents can no longer access any extensions (formats, filters, shortcodes, etc.).

"ignored" either using _ prefix or with:

project:
  render: 
    - "*.qmd"
    - "!ignorable/**.qmd"

Tested using 1.9.2 (dev)

Now being track in:

• Custom format not found in ignored subdir #13436

Yep, both document and project renders there the error. And indeed I bumped into this issue not using _ but using render targets. My default profile ignores a directory that a secondary profile unignores (the directory contains quizzes and the profiles are student and staff sites respectively). The build fails because it can’t find the custom format.
