thanks anyway
microservice story needed
just need the libraries you use in microservice, and the reason you use them, and of course the URL link.

D can serve up web stuff by itself too. did you mean vibe.d? but i want to use in a shared hosting environment where my options are : ruby, python, nodejs and as usual php vibe.d as standalone app will not work. i know kotlin with js support, but maybe there is another option .. thanks for your answer and insight.

Re: Old but interesting link as to the low adoption reason for D
When god (walter) create eden (dlang) the man (bo the biz developer) is very happy. Man thinks he is in heaven. Until man eat the forbidden apple(the ecosystem library, editor, tools). Now man understand he is in hell. Walter has created great language. But this language is not first class( first choice) on those platform. 1. Windows : .net , java etc 2. Ios : swift etc 3. Android : java kotlin, no d 4. Linux : c java, may be d , etc From what i understand( i am very sorry if i am wrong). D almost get customer, well almost. Bo was happy with the language but not ecosystem. For biz developer they expect very few bumps. This is normal. So what can d-community do : create subforum so that they know the bumps so they can avoid them. Ask what they are building (the general only), on what platform, what db, their background. Tell them what library you use, workaround, platform compiler odds tell them how you succeed. Provide them short cut : general build files, code management, idioms, etc. In short words : may be subforum for mentorship(can be free or paid). Separate from learn forum. It lowers heart attack , hipertension, anger, and disappointment. Today big companies like microsoft, apple create great languages for their platform AND partial supported language on other platform. Eg : swift for ios is official, swift on win is community. These language serve as honey because they give away for free to attracts us (the bee) so their product ecosystem (software or hardware) survive. D will never be rival for these language on that platform. For D to survive it must be the only champion on a platform or at least one of champion. My best guess is resource limited platform or /and linux. On those resource limited hardware platform, now, only 6 or 8 language but no clear champion ( for me, c and cpp not a champion, but i will use them if no alternative. ). I think betterc and nogc feature will make that happen. Lets hope so. But for now all d-community can do is serve that specific company need for success, for their thirst of money. And hope their feedback to the community when they want to leverage their requirement such as library used, running platform etc. Again i am sorry if i offend someone. Or i give you wrong info.

Your code is correct, it's your terminal or whatever you use to
see your program's output that doesn't flush stdout. You can
force it though:
string str;
writeln("Enter a string: ");
stdout.flush;
str = readln;
write(str);
Thank you, again.

simple newbie question
How to generate temporary files so compilation time speeds up. Normal compilation only produce obj, exe. If what i mean is that if we compile the files that unchanged, dmd will look for that temporary files instead of .d files.
simple newbie question
Hi. Dll or shared library is important feature of software development. So why most d library still static link. I am sorry for my stupid question. Thanks.
