5059 :: Roadmap Document?

• aiguy (orginal) [2019-07-30T22:08:51+02:00] view original

  Is there a roadmap document for Nim yet.

  I realize it is quickly approaching 1.0 but the future of the language and it's planned enhancements are as important for me as it's current feature set.

  There is no roadmap document but what it could become beyond V1 is debated in the RFCs repo: https://github.com/nim-lang/RFCs.

  The big items for V1 are:

  • tagged in https://github.com/nim-lang/Nim/milestone/2, especially make async and threads compatible (due to conflicting proc name and signature)
  • destructors: https://github.com/nim-lang/Nim/wiki/Destructors
  • Incremental compilation: https://github.com/nim-lang/RFCs/issues/46

  For future Nim version 2, the big things I see are:

  • borrow checking with owned refs (i.e. the --newruntime) https://github.com/nim-lang/RFCs/issues/144

  • GC-free standard library thanks to GC-free base types

    GC will still be available for user types.

  • Standard library much more multithreading friendly
  • Standard library much more embedded device friendly
  • concepts with dynamic dispatch via VTable see
    • https://nim-lang.org/docs/manual_experimental.html#concepts
    • Commented out VTable section

    This probably will imply a refactoring of methods, which started with putting multimethods behind a pragma.

  • better hot-code reloading see https://github.com/nim-lang/Nim/pull/11742. This will allow to build REPL, jupyter kernel and plugins
  • compiler plugins

  @mratsim On my to-do list for August is to take an initial look at Nim REPL options - so is the hot-loading work that was done recently still needing work to get a REPL going?

  Hot-reloading works but is still rough as it's not even 6 months old.

  You can probably already try building a REPL on top, but just make sure to not stay alone if you hit a bug, join the IRC/Gitter/Discord/Matrix.

  Alternatively for REPL you have

  • nim secret, unsupported secret command line option to get a limited REPL (it doesn't support anything that requires a C library)
  • INim - https://github.com/AndreiRegiani/INim, which works with plain raw Nim.

  Excellent - thanks - I'll take a look at it later this month.
