   Wow, #dpp, the D preprocessor.
   
   https://code.dlang.org/packages/dpp
   
   It takes an almost-D file that contains C-#includes, inserts those, translates any prototypes into the right D prototype in an extern(C) block, runs the result through the real cpp to expand any macros, and that becomes a D file that the normal compiler can compile.
   
   Sounds crazy, but apparently it's been tested to work for calling libcurl, openssl, nanomsg and a few others, and that's still early days. Kindasorta works with C++ if it's basically a C-compatible subset.

   Is the !dlang GC an issue for you as you're interfacing with your C and other non-D code?
   
   There is the -betterC mode, which is still pretty limiting (but no more than writing in C?), but it's being worked on. More and more of the standard library is being made available.
   
   https://dlang.org/blog/2017/08/23/d-as-a-better-c/
   
   There are methods for separating your GC code and your non-GC code in different threads, and you can make sure certain code parts (and everything they call) are free of GC with the @nogc attribute.
   
   There's also always the nuclear option of GC.disable. If you have safe points where you're not under scheduling pressure you can run GC.collect explicitly. I don't think there's a way to make the collection time bounded though, which would have been useful.
   
   https://wiki.dlang.org/Memory_Management#Real_Time
   
   Here's the start of a whole series on what to do about all this:
   
   https://dlang.org/blog/2017/06/16/life-in-the-fast-lane/
   
   > It can’t be repeated enough given how often it’s misunderstood: D’s GC will only have a chance to run when the programmer allocates GC memory and it will only run if it needs to. Use that knowledge to your advantage by keeping the allocations small, infrequent, and isolated outside your inner loops.

   Alright, so I did it. I revised my #d #programming blog post slightly.

   Now to wait for the next opportunity to sic it on unsuspecting readers, mwhahaha!

   > A not-so-well-written article about the fuzzing capability recently added to LDC, using LLVM’s libFuzzer. Compiling code with -fsanitize=fuzzer adds control-flow instrumentation used to guide the fuzzing and links-in the libFuzzer library that drives the fuzz testing (same as Clang). -fsanitize=fuzzer is available from LDC 1.4.0, not on Windows. LDC 1.6.0 was used for the examples in this article.

   Tried out subbing to the "BSD Now" podcast. Interesting, but the two episodes I've listened to are about four times too long and filled with babbling. Within 5-10 minutes, I've tuned out. #BSDNow
   
   I think I'm going to unsubscribe, which will leave me with two:
   * Hacker Public Radio -- I've resubbed for the past couple of weeks and I have not burned out yet. Maybe I'm just a fan of @klaatu ;-) #HPR
   * Smalltalk Reflections -- This one is on another unannounced hiatus. I should probably take a look around and see whether there are any other !Smalltalk podcasts in currently active production.
   
   I haven't really looked for them yet, but I'd be interested in trying out podcasts that focus mostly on !TclTk or !DLang.

    You can tell C++ is broken because it's been over 30 years now and it still hasn't fully incremented into D.

    esr continues to talk about a replacement for the #C-language
    http://esr.ibiblio.org/?p=7724&cpage=1
    
    He favors #Go, with #Rust as a second. Believes that !DLang's future was harmed by the Phobos vs Tango standard lib shootout a few years ago. Dismisses #Nim, #Ocaml for their lack of real-world usage. Believes that #CPlusPlus was a mistake that only got worse as it become more complex.

      Harmed? Delayed, maybe. D is growing faster than ever.
      
      OCaml and F# are used in the financial industry. But they probably won't replace C because people are scared of no-parens almost as much as they are scared of parens. A nice mix of parens of various shapes keeps people calm. :-)

      @clacke @lnxw48a1 I'm using #OCaml for #robotics and #controlsystems. I think it's very underestimated, because of shallow evaluations based on where it's currently used.

    > Main part of this feature is a new UDA `@dynamicCompile`.
    
    > You can mark with this attribute any function (including class methods and lambdas) and compilation and optimization of this function will be deferred to runtime.
    Dynamic compiler will use instruction set available on host, so application can utilize the best available instructions without sacrificing users with old hardware.
    
    You can also calculate or otherwise dynamically figure things out in runtime, and then compile with these values considered constant, so that the optimizer can remove dead code based on your values etc.
    
    This is really remarkable.

    Reading about changes in C++17 I notice the biggest impact are with the changes that move C++ closer to D. D is a hell of a lot better with regard to understandability though (as in no SFINAE, way less weird edge cases).

    tbh rust totally verifies me waiting so long to pick up go despite me having an interest in it. I waited almost 10 years after go was released and I love it. Rust is a language where I've poked my head in every few months since the alphas and gone "nope, not for my use case" every time.

      Back when I used it in the 1.x days there were 2 competing compilers, 1 proprietary (dmd) and 1 not iffily supported but free (gdc). There were also 2 standard libraries: phobos (came with the lang) or tango (much better). Apparently phobos has gotten better and DMD got relicensed under the boost license.

      By competing compilers I did mean competing compilers, not like go or (presumably) D now: I recall running into libraries which were specifically dmd only or gdc only, plus gdc tended to lag behind in the specs. It wasn't a good time but I could see the potential.

      @awg Sent this to a friend who complained that his two equivalent implementations in !dlang and Rust took 0.1 s and 7.5 s respectively to compile. He likes to run the real compile and unit tests through flycheck, because when you're using D you can actually do that.

    Possible in !dlang :
    
    static assert(!__traits(compiles,{ ... }))
    
    Assert that { ... } does not compile. In this case, that a scope is enforced properly.
