 | once again dconf contains people who talk about compile speed as if it can be slow What are they doing? Even my worse compile time abstraction was O(n^2) or maybe some awful string concatenation of an entire file; still effectively instant Wheres a 1000 line file that does something meta programmingly useful that takes 5 minutes? Do they lose track of what the compiler is even doing? Do they turn off the template recursion depth limit? | |||

Do they lose track of what the compiler is even doing? Do they turn off the template recursion depth limit? No idea. Maybe they should use shell + awk + sed more. This is how chads generate code blazingly fast. | |||

Thats the runtime and std self importing everything and if your being wrong dub taking an entire 1/2 second to consider how to to call one of the easiest to work with compilers Th dub thing is straight stupid, the std should have a dag of acceptable imports, and the runtime is unfortunate fixed cost. But even if dub is in play with its unacceptable half sec to read a 10 line json, it isnt the "90 minutes" weka compile they talk about. | |||

C with tcc is faster than D an GO. | |||

Do they lose track of what the compiler is even doing? Do they turn off the template recursion depth limit? I have godot-dlang builds (with dub/LDC) compiling for about 3 minutes on top hardware. But this is more of a config issues and how LDC handles all that code symbols(functions, etc...), having to build a spaghetti templates for over 1k classes is no joke. This is something i am planning to look into, having a tiny WASM game scripts for 30 Mb shared library is no fun. This is mainly because it uses dub import-paths AND source-paths together for usability simplicity reasons. Would be much faster to remove source-paths and properly configure D's -i include pattern, that requires figuring dub configuration that properly uses predefined env variables. | |||
