This fixes#8823 by setting the current working directory we use when
launching our own `prettier` process via `node` to the project path.
Why does this fix it?
We already *did* read the correct configuration options for `prettier`
from any configuration files, we also correctly inferred which
`prettier` plugins to use, but somehow when running
./node_modules/.bin/prettier my-file.tsx
produced different results compared to `prettier` in Zed.
But we *do* pass the right options to `prettier.format` when calling it
here:
996f1036fc/crates/prettier/src/prettier_server.js (L177-L190)
I checked those against the `prettier --loglevel=debug` output: they're
the same.
Turns out that the difference is we launch our `prettier_server.js` (a
JavaScript shim that wraps `prettier`-the-library in a language server
interface) not in the project path.
So somewhere inside `prettier.format` something is `require`d and fails
because we're not in that project directory. But when you run
`./node_modules/.bin/prettier` you are.
With the fix here, `prettier` now correctly picks up the tailwind plugin
that didn't seem to work in #8823. It probably fixes a bunch of other
oddities that folks reported with `prettier` too.
Release Notes:
- Fixed `prettier` integration not correctly picking up `prettier`
plugins, because it didn't run in the project's root path when invoked.
