Please drop any though about scripting! #109

Hi First of all: I am amazed by your project! In my opinion there is huge need for true C++ cross platform library (desktop, mobile and embeded). I like every you do, but one thing I hate: Scripting language. Please drop this mad idea entirely! This kill Qt in my eyes an in my heart. There are at least few reasons to not implement this:

  1. It consumes a lot of time. You have more important things to do: multiplatform and first release.
  2. It require from C++ programmer write mad code - please do not force us to this night mare like in Qt.
  3. It works slow - we are C++ programmers because of unbeatable speed (among others advantages).

keep working and best regards Szyk Cech

Hi Szyk,

Thanks for you interest in neogfx!

Originally neogfx was just going to be a C++ GUI library for which, I agree with you, has little need for a scripting engine however the scope of neogfx has changed. neogfx is now a C++ app/game engine for which a scripting language is more appropriate but you should not be concerned for three reasons:

  1. Using a scripting language is entirely optional: there is nothing you can do with a scripting language that you cannot do easily using native C++; a scripting language is just a convenience for those who want a more dynamic approach.
  2. The scripting engine neogfx will use, "neos", will support multiple "standard" scripting/programming languages in addition to the neogfx scripting language "neoscript". neos will also have a JIT which should alleviate concerns about it being slow.
  3. I will resume mainline neogfx development once neos and neoscript are in a usable state; work on support for other languages in neos will be done in slow time.

Regards, Leigh Johnston.

cling based C++ as scripting language / hot code reload Why? Able to run C++ script in runtime or compile it for max speed ( as in example https://github.com/derofim/cling-cmake ) Also: May be used to improve modules compile time

HOT code reload possible approaches:

store app state fix cling undo for files https://root-forum.cern.ch/t/loading-unloading-class-as-interpreted-macro-in-cling-multiple-times/32976/2

execute cling code to change callbacks & variables nested cling::Interpreter with multiple cling::MetaProcessor IDK how to do it, but you can create child cling::Interpreter

Hi blockspacer,

neoGFX will be using neos (https://neos.dev) for its scripting.

Regards, Leigh Johnston.

neos seems very cool.

Note that Cling may be used to improve development workflow, not only as scripting engine.

Develop much faster with Cling help (dev/debug build of existing code), release same code compiled without Cling at all (release build).
