What This Plugin Does

Provides Neovim diagnostics and quickfix code actions for Scala effect libraries:

// ZIO examples
ZIO.succeed(())          →  ZIO.unit
.map(_ => ())            →  .unit
.catchAll(_ => ZIO.unit) →  .ignore

// Cats-Effect examples
IO(println(x))           →  IO.println(x)
io.map(_ => ())          →  io.void
