I frequently find it useful for a text data file parser to call a diagnostic callback instead of assuming some default behavior (whether that's forgiving, printing warnings, throwing or something else). With template callback parameters the parser can throw if the user wants it or stay pure nothrow if no action is required.

`temp = input.save` is exactly what you want here, which means
forward range is required. Your example won't work for range
objects with reference semantics.

Still, I would first try to submit a PR to syscall-d, and only go for a new package if syscall-d owners refuse to extend the list of platforms. Now we have two different packages that are supposed to do the same but have different arbitrary limitations.

While I can say that D can perform technically the same feat via pragma(msg, ...) and importing a file directly (would leave a comment on the blog, but there isn't a spot for it), the fact that you can execute arbitrary code in a block at compile time that can use the *actual* i/o routines you would use at runtime is pretty impressive. Stefan would have a field day with this power :) Yeah, it feels C++'y when you need to leave CTFE if you want to print some value computed in CTFE or use it as a name of file to load. :/

The font is much thinner than on dlang.org main site (font-weight set to 300 for no good reason), and thus much harder to read. Using #333 for text color instead of pure black makes it even harder. Come on, perhaps most of us already have some sort of vision defects, please do not make it worse. 2. Project READMEs now render with different font which looks weird. (OTOH, the README alone looks nicer and easier on eyes, because plain Helvetica or Arial are just better suited for on-screen reading than clumsy serif fonts like roboto slab). 3. Clicking the top-left dub logo directs to "http://code.dlang.org/packages/; which is 404. 4. List of available versions for a package is broken: the most recent version is repeated multiple times and is not a hyperlink. Also, some parts of READMEs are not rendered the way they are on github, like: nested lists, [ ]/[x] progress ticks, syntax highlighting in code snippets.

Take a look: http://dconf.org The "Register" link is now missing, but when I click "Venue", I can see "Register" and the old logo. Btw, how about making the entire top bar purple to match the logo (maybe the menu bar could be turned D-red instead)?

Re: Hash Tables in D
On Sunday, 3 January 2016 at 19:29:05 UTC, Martin Nowak wrote: There is a bug. You should never do this b/c of iterator/range invalidation. foreach (key; aa.keys) aa.remove(key); I've recently hit this when trying to remove some of the elements from an AA while iterating over it. It's easy to forget that it is not allowed, especially when working on more complex algorithms. Accidentally, it worked all fine even with large data sets with DMD 2.069, but with GDC mysterious segfaults appeared - the first thought in such case was obviously a bug in GDC or in the older front-end. However, this is a very convenient, natural and intuitive syntax for something that is needed quite frequently, yet this code breaks silently in non-predictable ways. There are already registered issues concerning this (or similar with insertion) problem, including: https://issues.dlang.org/show_bug.cgi?id=4179 https://issues.dlang.org/show_bug.cgi?id=2255 https://issues.dlang.org/show_bug.cgi?id=10821 https://issues.dlang.org/show_bug.cgi?id=10876 https://issues.dlang.org/show_bug.cgi?id=13903 I've personally encountered segfaults, infinite loops, programs producing incorrect results. Some solutions to this were proposed in the bug reports - either: a) explicitly allow removing during iteration, and make sure it always works, or b) explicitly disallow removing during iteration, and always throw an Error whenever it is attempted. In some cases it could even be detectable in compile time. And I don't mean including a single sentence about this somewhere in the docs. I mean an error reported by the compiler and/or runtime. The runtime checks could be disabled for -release, but there should be at least an option to detect such errors. Probably the worst part of it is that you're free to wrap it in @safe, while it's not safe at all.
