    While all these values can be set here, they are here only for compatibility with clients that were setting them this way.

  27. final class Compilations extends AnyRef
  28. class CompilerPlugins extends AnyRef

    Responsible for disabling unsupported compiler plugins.

    Responsible for disabling unsupported compiler plugins.

    Metals only uses the presentation compiler for limited features - completions - hover - parameter hints Compiler plugins that don't affect those features can be disabled, for example WartRemover that only reports diagnostics. Diagnostics are already published from the build, where all compiler plugins are enabled by default.

    Some compiler plugins change the semantics of the Scala language. Metals officially only supports a hardcoded list of such compiler plugins: - kind-projector, introduces new syntax for anonymous type lambdas - better-monadic-for, changes for comprehension desugaring The IntelliJ Scala plugin has custom support for these plugins.

    Notably, macro-paradise-plugin id disabled because it does not work with the -Ymacro-expand:discard setting making completions always fail when inside an expanded tree.

    The process for adding support for other compiler plugins is the following, send a PR to Metals adding integration tests to demonstrate thee compiler plugin - needs to be enabled in order for completions/hover to function. Many plugins like WartRemover that only use the compiler report don't need to be enabled. - enabling the plugin does not break the presentation compiler in unexpected ways.

    Implements goto definition that works even in code that doesn't parse.

    Uses token edit-distance to align identifiers in the current open buffer with symbol occurrences from the latest SemanticDB snapshot.

    The implementation logic for converting positions between the latest SemanticDB snapshot and current open buffer is quite hairy. We need to convert positions in both the "source" (where definition request is made) and the "destination" (location of the symbol definition). This requires using token edit distance twice:

    - source: dirty buffer -> snapshot - destination: snapshot -> dirty buffer

  43. final class Diagnostics extends AnyRef

    Converts diagnostics from the build server and Scalameta parser into LSP diagnostics.

    Converts diagnostics from the build server and Scalameta parser into LSP diagnostics.

    BSP diagnostics have different semantics from LSP diagnostics with regards to how they are published. BSP diagnostics can be accumulated when reset=false, meaning the client (Metals) is responsible for aggregating multiple build/publishDiagnostics notifications into a single textDocument/publishDiagnostics notification.

    Another challenge is to consolidate syntax errors on every keystroke with type errors on batch compile because positions get stale in batch compile errors as you type new syntax errors. To solve this problem we use token edit distance the same way we support goto definition in stale buffers.

  82. final class MetalsHttpClient extends DelegatingLanguageClient

    Editor client that implement dialogue UIs like window/showMessageRequest.

    Editor client that implement dialogue UIs like window/showMessageRequest.

    Goals:

    - enable editor plugin authors access all functionality within Metals even if the editor plugin only supports a limited set of LSP endpoints.

    Non-goals:

    - Pretty UI, the interface only needs to be functional, not look nice. - Become permanent/primary interface for ordinary users. The end goal is to enable users to interact with Metals from their editor, not via a browser.

    The most popular LSP clients in editors like Vim currently have limited support so that endpoints like window/showMessageRequest are ignored, with no workaround for users to interact with the Metals language server. This http client allows users in those editors to trigger server commands and respond to UI dialogues through their browser instead.

    Manages sending metals/status notifications to the editor client.

    Some design constraints and design decisions: - we should publish no more than status update per second so the user has time to read the notification. - there is only one active status bar notification at each time, in case there are multiple candidates we pick the item with higher priority. - it's acceptable that a low priority notification may never appear in the status bar. - long-running jobs like compilation or "import workspace" are active as long as the attached Future[_] is not completed.

  11. object CancelTokens

    Constructs an async CancelToken.

    Constructs an async CancelToken.

    The CancelChecker API in lsp4j is un-sufficient for our needs because we want to get a Future[Boolean] that completes to true when the user cancels a request, allowing us to abort expensive computation like typechecking as soon as possible. With CancelChecker, we need to explicitly call token.checkCancelled(), which is not possible inside the compiler.

    One stop shop for all extension methods that are used in the metals build.

    Usage:

    import scala.meta.internal.metals.MetalsEnrichments._
    List(1).asJava
    Future(1).asJava
    // ...

    Includes the following converters from the standard library:

    import scala.compat.java8.FutureConverters._
    import scala.meta.internal.jdk.CollectionConverters._

    If this doesn't scale because we have too many unrelated extension methods then we can split this up, but for now it's really convenient to have to remember only one import.
