Hello,

I noticed that importing some std libraries causes the build time to jump to around 1 - 3 secs.

I started creating my own helper functions to avoid importing std for scripting and prototyping in order to keep the compile time at around 0.5 secs.

I was wondering if anyone knows of any libraries that are geared towards something like this?

Thanks

What part of std? Have you tried selective imports?

Don't know specifically, but I tried doing this and it always eventually creeps over 2secs. Even with gold linker or rdmd.

Having a library with bare minimum meta programming would help with this I think. I'm willing to pay the cost of safety.

Strange, usual D programs builds fast.

As a alternative to Phobos, you can see to D1 standard library - Tango, ported to D2.
https://github.com/SiegeLord/Tango-D2

Without mass template magic, its easier.

There is also print book "Learn to Tango with D".

Thanks! I'll take a look.

What build times do you get?

Seems like some other people have similar issues:

All you mentioned are template issues. Some was fixed.

I test full rebuild of dlang-IDE (20k loc) now for dmd under Windows:
(Result is 5.5Mb .exe file)

-full rebuild with all libs take ~21s  >dub build --build=debug --arch=x86_mscoff --force

-change one file and rebuild <7s  >dub build --build=debug --arch=x86_mscoff

Update, 20k loc without  counting libraries.

Thanks for the info.

Yeah the times I'm trying to reach are around 0.5secs so as to have the same feel as a scripting language.

I'm having some success pulling out small bits of code from other libraries and keeping things minimal and c-style-ish.

If you're really ok with minimalism, I'm writing such a library https://filebin.net/7gtyh5j01gk1ofly
I didn't publish it anywhere yet, feel free to do so. Not everything is finished there yet.

I was too looking for something like this, thanks! you should definitely host it somewhere, maybe on github, i'd love to contribute!
