Here's the file structure of a project:
$ pwd
~/my/project
$ ls
src/ Cargo.toml style.css default.nix
$ cat style.css
@import "tailwindcss";
The index.html file is generated with nix, and is located outside the project at /nix/store/9naz5isizpi8xyj55ba328pk3nxrfiaz-index.html. Currently it looks like this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

My build fails because my index.css file is in another folder. A workaround is to wrap the build in a script to copy the html file prior to the build, and gitignore it:
cp /nix/store/9naz5isizpi8xyj55ba328pk3nxrfiaz-index.html index.html
trunk build index.html
That works, but it pollutes the directory in my opinion, I would like the project directory to only contain source files.
I was thinking of introducing a configuration flag to override the pre_target in

let target_parent = target |
to have it work something like this:
$ pwd
~/my/project
trunk build /nix/store/9naz5isizpi8xyj55ba328pk3nxrfiaz-index.html --pre_target $PWD
It could also be in the TOML file and as an env variable, of course.
