`Workspace` is responsible for creating the `BuildSystemManager` and responds to most of the delegate calls. It should thus also be the delegate of `BuildSystemManager`.
This way we create the `BuiltInBuildSystem` at the same time that we create the `BuildSystemManager`, which gets us one step closer to creating the `BuiltInBuildSystem` from the `BuiltInBuildSystemAdapter`.
This allows us to create the build system from a `BuiltInBuildSystemAdapter` when it receives an `InitializeRequest`, which will be done in a follow-up commit.
We were making the initial `generateBuildGraph` call in `SourceKitLSPServer` from a `Task`. This means that `generateBuildGraph` could be executed after `waitForUpToDateBuildGraph` was called by `SemanticIndexManager`. Thus `waitForUpToDateBuildGraph` returned immediately and no files were background indexed.
Make `generateBuildGraph` immediately schedule a package reload for SwiftPM build systems instead of doing the hop through a `Task`, fixing the race condition.

We currently load the entire package before generating a `SwiftPMBuildSystem`. That means that the initialize request to SourceKit-LSP is blocked until the package has been loaded, preventing us from offering any sort of functionality, including syntactic functionality like formatting.
Decouple build system creation and build graph generation (aka. package loading for SwiftPM). We can operate with fallback build settings until the build graph has been loaded and reopen the document once the proper build settings are available.

We forgot to decode the following keys in the custom decode function, which meant that you couldn’t set them using SourceKit-LSP’s `config.json` file.
- `backgroundPreparationMode`
- `sourcekitdRequestTimeout`
- `cancelTextDocumentRequestsOnEditAndClose`
We had the custom decoder function so that the keys weren’t required in the JSON but we could access eg. `SwiftPMOptions` without needing to deal with optionals in the codebase.
Make the accesses to these nested options structs a little more verbose but eliminate the source of the above bug, which seems like a good tradeoff.
The basic idea is that a `sourcekit-lsp://swift-macro-expansion` URL should have sufficient information to reconstruct the contents of that macro buffer without relying on any state in SourceKit-LSP. The benefit of not having any cross-request state in SourceKit-LSP is that an editor might can send the `workspace/getReferenceDocument` request at any time and it will succeed independent of the previous requests. Furthermore, we can always get the contents of the macro expansion to form a `DocumentSnapshot`, which can be used to provide semantic functionality inside macro expansion buffers.
To do that, the `sourcekit-lsp:` URL scheme was changed to have a parent instead of a `primary`, which is the URI of the document that the buffer was expanded from. For nested macro expansions, this will be a `sourcekit-lsp://swift-macro-expansion` URL itself.
With that parent, we can reconstruct the macro expansion chain all the way from the primary source file. To avoid sending the same expand macro request to sourcekitd all the time, we introduce `MacroExpansionManager`, which caches the last 10 macro expansions.
`SwiftLanguageService` now has a `latestSnapshot` method that returns the contents of the reference document when asked for a reference document URL and only consults the document manager for other URIs. To support semantic functionality in macro expansion buffers, we need to call that `latestSnapshot` method so we have a document snapshot of the macro expansion buffer for position conversions and pass the following to the sourcekitd requests.
```
keys.sourceFile: snapshot.uri.sourcekitdSourceFile,
keys.primaryFile: snapshot.uri.primaryFile?.pseudoPath,
```
We should consider if there’s a way to make the `latestSnapshot` method on `documentManager` less accessible so that the method which also returns snapshots for reference documents is the one being used by default.

As a user makes an edit to a file, these requests are most likely no longer relevant. It also makes sure that a long-running sourcekitd request can't block the entire language server if the client does not cancel all requests. For example, consider the following sequence of requests:
- `textDocument/semanticTokens/full` for document A
- `textDocument/didChange` for document A
- `textDocument/formatting` for document A
If the editor is not cancelling the semantic tokens request on edit (like VS Code does), then the `didChange` notification is blocked on the semantic tokens request finishing. Hence, we also can't run the `textDocument/formatting` request. Cancelling the semantic tokens on the edit fixes the issue.

Do one of the following for every `FIXME` or `TODO` comment
- Add an issue that tracks the task
- Remove the comment if we are not planning to address it
An accessor is a child of the corresponding variable, which is why we failed to compute the correct container for them. Look one `childOf` relation further for accessors to fix this.

This will log

instead of
```

```
```
The SwiftPM build system integration was the only one in its own modules. Merge it into the `BuildSystemIntegration` modules next to eg. the compilation database build system.
As part of its initialization options the client can pass a
textDocument/codeLens object that lists the supported commands the
client can handle.
It is in the form of a dictionary where the key is the lens name
recognized by SourceKit-LSP and the value is the command as recognized
by the client.
```
initializationOptions: {
"textDocument/codeLens": {
supportedCommands: {
"swift.run": "clientCommandName_Run",
"swift.debug": "clientCommandName_Debug",
}
}
}
```
Adds a response to the textDocument/codeLens request that returns two
code lenses on the `@main` attribute of an application.
The LSP documentation breaks out the code lens requests into a
[`Code Lens Request`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_codeLens)
and a
[`Code Lens Resolve Request`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#codeLens_resolve),
stating this is for performance reasons. However, there is no intensive
work we need to do in order to resolve the commands for a CodeLens;
we know them based on context at the time of discovery. For this reason
we return resolved lenses with Commands for code lens requests.
A missing piece is only returning code lenses if the file resides in an
executable product. To my knoledge Libraries and Plugins can't have an
`@main` entrypoint and so it doesn't make sense to provide these code
lenses in those contexts.
Some guidance is required on how to best determine if the textDocument
in the request is within an executable product.
`testCodeLensRequestWithInvalidProduct` asserts that no lenses are
returned with the `@main` attribute is on a file in a `.executable`, and
is currently failing until this is addressed.
Change a l public declarations to the `package` access level, accept for:
- The `LanguageServerProtocol` module
- The `BuildServerProtocol` module
- `InProcessClient.InProcessSourceKitLSPClient`
- `LanguageServerProtocolJSONRPC` (I would like to create a more ergonomic API for this like `InProcessSourceKitLSPClient` in the future, but for now, we’ll leave it public)
Unfortunately, our pattern of marking functions as `@_spi(Testing) public` no longer works with the `package` access level because declarations at the `package` access level cannot be marked as SPI. I have decided to just mark these functions as `package`. Alternatives would be:
- Add an underscore to these functions, like we did for functions exposed for testing before the introduction of `SPI`
- Use `@testable` import in the test targets and mark the methods as `internal`

This implements an LSP Extension `PeekDocumentsRequest` to let `ExpandMacroCommand` to open the macro expansions in a "peeked" editor window.
For this to work, the client has to pass "workspace/peekDocuments" enabled to `ClientCapabilities.experimental` and the client should handle the `PeekDocumentsRequest` and show the expansions in a "peeked" editor window.
PR to support the above capability in the "Swift for VS Code" Extension: https://github.com/swiftlang/vscode-swift/pull/945
The "Swift for VS Code" extension cannot send the client capability, so it instead passes the same through `initializationOptions` in the `InitializeRequest`.
For editors which doesn't support this capability, `sourcekit-lsp` sends a `ShowDocumentRequest`.
The `ShowDocumentRequest` is updated to show all the macro expansions in a single generated file. Moreover, its folder structure is updated to use hex string of MD5 hash of concatenation of buffer names of expansions.

This allows us to flip the default in the future more easily. It also allows users to disable background indexing when it’s enabled by default.

The idea here is to unify the different ways in which we can currently set options on SourceKit-LSP in a scalable way: Environment variables, command line arguments to `sourcekit-lsp` and initialization options.
The idea is that a user can define a `~/.sourcekit-lsp/.sourcekit-lsp` file (we store logs in `~/.sourcekit-lsp/logs` on non-Darwin platforms), which will be used as the default configuration for all SourceKit-LSP instances. They can also place a `.sourcekit-lsp` file in the root of a workspace to configure SourceKit-LSP for that project specifically, eg. setting arguments that need to be passed to `swift build` for that project and which thus also need to be set on SourceKit-LSP.
For compatibility reasons, I’m mapping the existing command line options into the new options structure for now. I hope to delete the command line arguments in the future and solely rely on `.sourcekit-lsp` configuration files.
Environment variable will be migrated to `.sourcekit-lsp` in a follow-up commit.
