Notes

  • in ghci, do let main = Main.main > :main -m etc to disambiguate between different mains that may be in scope (this happens in HIE)

  • in HIE, running the tests a second time results in this: ** Exception: ./test-main.log: openFile: resource busy (file is locked) for HIE, we'd need let main = hspec Spec.spec. this may different on a per-project basis, so put it in configuration? dhall config file? workspace settings?

  • Discovered tests are organized by module name, minus "Spec". I.e., ApplyRefactPluginSpec -> ApplyRefactPlugin

    • But NOT non-discovered tests (see stack ghci --with-ghc intero haskell-ide-engine:test:haskell-ide-func-test haskell-ide-engine:lib)

  • maybe defer type errors, so we can show code lenses for partially type checked programs

  • when a target fails to load, keep a record of it in "failed" state.

    • when a file changes, we:
      • try to find the target it belongs to; if we find it, reload it
      • otherwise, see if there's any target in the failed state, :r it
      • if :r still fails, move onto the next failed target
      • if there are no failed targets, do nothing

  • when a file is added

    • :r a target
    • ???? we can't use all-types, because the file may have no expressions in it yet

  • Do expressions of type [Char] become of type IsString s => s when -XOverloadedStrings is enabled?

  • Try replacing utils/map/Map with es2015's native Map (needs map and filter functions)

  • Have a look at TextDocuments.syncKind

  • what if changes are made while intero is loading??

  • when the "run all tests [in file/in project]" vscode option is triggered, forcefully save file and then run tests
