## Purpose
While developing a theme for Zed I remarked that the schema available
doesn't mark colors in a way that Zed recognize to display the color
annotations:
```json
{
"$schema": "https://zed.dev/schema/themes/v0.2.0.json"
}
```
<img width="119" height="190" alt="Screenshot 2026-02-25 at 23 15 10"
src="https://github.com/user-attachments/assets/3f1bb703-cb26-4630-9598-3a7cb8873c20"
/>
But Zed has support for it when colors are marked with `"format":
"color"` in the schema:
<img width="127" height="186" alt="Screenshot 2026-02-25 at 23 14 58"
src="https://github.com/user-attachments/assets/1a9387a4-613a-4cf8-a3af-f6ac201bdf54"
/>
So I searched if the schema file was Open Source somewhere, discovered
it was generated from the codebase and attempted the change.
## Implementation
This is essentially done using a `ThemeColor` wrapper for the color
strings that implements `JsonSchema` with a dedicated regex for
validation and the color format specified. This ends up with a new
`$defs` of `Color` being specified and used:
```json
{
"$defs": {
"Color": {
"type": "string",
"format": "color",
"pattern": "^#([0-9a-fA-F]{3}|[0-9a-fA-F]{4}|[0-9a-fA-F]{6}|[0-9a-fA-F]{8})$"
}
}
}
```
## Other
- There is a small change I made for testing to the schema_generator
that adds an `--output` / `-o` flag. When provided it writes the
generated schema JSON to the specified file path instead of printing to
stdout. This was done to made testing easier but I can remove it or
split it to a separate PR (It's already a separate commit)
- For this PR to do anything a new schema version will need to be
published at something like `https://zed.dev/schema/themes/v0.3.0.json`
and documentation needs to be updated to point to it.

Release Notes:
- Added project settings schema to the schema_generator CLI. This allows
for exporting the project settings schema as JSON for use in other
tools.
We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

This adds a "workspace-hack" crate, see
[mozilla's](https://hg.mozilla.org/mozilla-central/file/3a265fdc9f33e5946f0ca0a04af73acd7e6d1a39/build/workspace-hack/Cargo.toml#l7)
for a concise explanation of why this is useful. For us in practice this
means that if I were to run all the tests (`cargo nextest r
--workspace`) and then `cargo r`, all the deps from the previous cargo
command will be reused. Before this PR it would rebuild many deps due to
resolving different sets of features for them. For me this frequently
caused long rebuilds when things "should" already be cached.
To avoid manually maintaining our workspace-hack crate, we will use
[cargo hakari](https://docs.rs/cargo-hakari) to update the build files
when there's a necessary change. I've added a step to CI that checks
whether the workspace-hack crate is up to date, and instructs you to
re-run `script/update-workspace-hack` when it fails.
Finally, to make sure that people can still depend on crates in our
workspace without pulling in all the workspace deps, we use a `[patch]`
section following [hakari's
instructions](https://docs.rs/cargo-hakari/0.9.36/cargo_hakari/patch_directive/index.html)
One possible followup task would be making guppy use our
`rust-toolchain.toml` instead of having to duplicate that list in its
config, I opened an issue for that upstream: guppy-rs/guppy#481.
TODO:
- [x] Fix the extension test failure
- [x] Ensure the dev dependencies aren't being unified by Hakari into
the main dependencies
- [x] Ensure that the remote-server binary continues to not depend on
LibSSL

This PR adds a `schema_generator` crate that can be used to generate our
various JSON schemas for publishing elsewhere.
Currently it does the simplest thing possible and just prints the JSON
schema to stdout. We can make this a but more robust later.
I also removed the schema-printing facilities from the `theme_importer`,
as they don't really make sense there.
