    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

    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.

     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.
