August 28 Is D painted into a corner? | ||||
|---|---|---|---|---|
| ||||
 | It seems like 'templates' are the 'Achilles heel' of D. Without starting a flame war, has D gotten to the point where ordinary mortals have difficulty coding in D with 'templates' such as 'cycle' requiring rewrites into 'myCycle'? Does D now require 'deep' memory into layers of history and workarounds? Is D a general purpose language, suitable for Application Programming, or does it have a more limited scope? | |||

Can you elaborate? So what’s the point? | |||

No, d is often forward toward this issue. Many PL dont even handle forward references. >Does D now require 'deep' memory into layers of history and workarounds?

Great work btw. >It seems like 'templates' are the 'Achilles heel' of D. has D gotten to the point where ordinary mortals have difficulty coding in D with 'templates' such as 'cycle' requiring rewrites into 'myCycle'? Phoboes isnt all of d; templates are the feature on offer. You can leave safetyism at any time, it doesn't matter that the cia wants you to use rust, or that society's whats to "prevent every nuclear death" while still mining coal. You can take a walk during a thunder storm or mimik my style of code, or let a child play outside at any time. You will be called stupid or insane all the time, but when its implied that safety is the highest moral standard without any justification you can just say "nah". >Is D a general purpose language, suitable for Application Programming, or does it have a more limited scope? Safetyism is also over in c++ to some degree and its a founding principal of rust; the fact I could give you 10 lines to define cycle of simple code is a virtue. | |||

I'm not sure what you mean by this, or where you're getting this information from, but this is completely wrong. D's templates, which are part of its metaprogramming capabilities, are the primary reason I even use D at all. Take away templates, and I would lose 80% of the reason I use D. Now I'm not saying there isn't room for improvement. There's always room for improvement when it comes to reducing template bloat, increasing compile speed when dealing with template-heavy code, etc., but getting rid of templates is totally not the solution. And they are hardly the "Achilles heel of D", whatever that means. They are a very big part of why D is so awesome. Pre-template D (I believe that's 1.0 or maybe even before that) was pretty lackluster IMNSHO; it wouldn't have registered on my radar back when I got fed up with C++ and was looking for a better language. T -- Elegant or ugly code as well as fine or rude sentences have something in common: they don't depend on the language. -- Luca De Vitis | |||

Everyone, thanks for your comments. What would you recommend to learn the current version of D language, for a professional developer familiar with IBM 1620 machine language with punch cards, C, C++, Rust, PL/I, Fortran, C# and APL, among others. The 'old book' pdf seems to be the most current approach, and it should only be about 3 years old. | |||

The 'old book' pdf seems to be the most current approach, and it should only be about 3 years old. my stuff: https://github.com/crazymonkyyy/dingbats //you probaly dont need this after reading the book, but my style cough is better and far more terse https://crazymonkyyy.github.io/blackmagic-in-d/ both obviously in incomplete states. If you couldnt read https://www.youtube.com/watch?v=U6I-Kwj-AvY&list=PLVFrD1dmDdvf8REa4SkI-IppFGvkRq83O Syntax test, syntax test, syntax test; just try 30 lines of code at a time, every time you go to write 100 lines of program, verify what you think is possible in a syntax test; and every once in a while try something you think is impossible theres stuff in there that no one talks about. | |||

The fact that it uses D is helpful on many levels. There are some old concepts in there like OOP and strong exception guarantees but I claim the content is still usable today. I find the book extremely useful myself and use it almost daily to look up features of the language. Ali | |||
