on HN thread What's wrong with the default build tool for Scala

[link] may be too low-level for what you envision, but captures a lot of your ideas, I think. [link] has a presentation. It focuses on compiling with clang, but the system is more flexible. Slides at [link] , matching video is at [this video] .

Presentation on llbuild's flexible build system design.

on HN thread Announcing Remacs: Porting Emacs to Rust

If you are on Windows, VS 2015 and the upcoming VS 2016 have lots of improvements regarding compile times. [link] [link] [link] Apple is also doing a similar work regarding incremental C and C++ builds, based on the work they did for Swift [this video] C++ builds can be made bearable if you don't go crazy with template meta-programming, do forward declarations, only expose actually public data on the headers, instantiate most use templates. But specially do use binary libraries, even across application modules. Don't spend endless time recompiling code that doesn't change.

on HN thread The Little Things: Speeding up C++ compilation

Is this like llbuild? [this video] [link] I remember watching the talk awhile ago, but haven't kept up with its progress. It's about using LLVM as a library to eliminate duplicate work, as far as I remember. I think it was for C++ as well as Swift.
