The type returned from Test1() is a `RangeT!(Array!string)`.
This is due to the `[]` on the end of `Fs[]`.

Realtime monitoring of GC
In the Java world, the JVM offers hooks to allow tools to monitor in real time what is happening under the hood of your application. I think this sort of tooling would be very useful in D. Especially in my current Game Dev project (it'd be really nice to see in real time where you're allocating). I've had a quick look, and the current -profile=gc code should be pretty adaptable. We'd just have to make available a public 'getter' of the current accumulated stats in profilegc.d [1]. I'm no compiler programmer, so: 1) I'm here looking for advice on whether this is even the correct way to go about it? 2) What would be the best way to make it available to the end user? Through a function call in core.runtime? Or maybe a compiler switch that prints to a file every X seconds? My current (hacky) attempt is here [2]: It copy/paste from other code, and would need cleaning up. But, it's a proof of concept at least. I provide access to user code through a function in core.runtime; It's in use in sample code here: [3] Thanks!

I notice the ST3 plugin was a bit... flaky the last time I tried it (admittedly about 6 months ago). I ended up settling on vim with a few plugins (and live without auto-complete, it's not that important for me), but when I was using GUI text editors, I settled on VS Code with the code-d plugin. Its autocomplete etc worked pretty much out of the box for me. https://code.visualstudio.com/ https://marketplace.visualstudio.com/items?itemName=webfreak.code-d Make sure you follow the 'dependencies' section of code-d through though to get your env set up.

There are venues such as Coventry, the Techno Park has a great venue for up to about 200 people and fairly cheap and very local accommodation.

PyConIE is in the Radisson, which is very central and handy for everyone. Theres many many other venues around the city too - including the RDS which has oceans of event space.

Thanks. Also it has spawnInPty Cool. Any questions on using it let me know. I'm all for a bit of feedback also! I tried dexpect, now it works for the bash emulation! Good - glad it works! But there are still some issues: Bad - but to be expected :) 1. Spawn's data is a string, so it stores ALL data, but Expect class does not have a clear() method, so the data piles up and takes memory. Yeah, this was something I came across too but didn't have the time to fix it. My plan is to have the Expect class take an OutputRange, and all output is then sent to that Range. The only data that it keeps track of then is the data just before and since the latest 'expect' call. 2. There seems to be a visible lag for each send->read cycle. I haven't look in the details to find where, but it feels not as smooth as ssh does. I have added a good few Thread.sleep function calls in the send / read calls. This is because it seemed to crash out when there was nothing there and I needed something quick to get it working at the time. There must be a better way of handling this though. Also, I suspect I've added way too many sleep calls so I should do a bit of work on this! 3. when hiting 'vim a.file' on the command, things go messy. Have you got these interactive commands work in dexpect? Yeah, dexpect won't be handling something like vim. As Adam said, it sends lots of signals / commands to the terminal to tell it how to draw the window. Dexpect just cares about reading the data sent to/from the process, not what any of that data means. My wish list for the Expect class ( or design a separate class, like BashProxy ): 1. Fully proxy for a bash shell. 2. Result data are separated for each command. So I can easily search for hitorical sent commands or results. This would be cool. I'll have a think about how to go about it! But for now it works fine for my needs. I'll try to improve it when I get major parts of my repl lib done. Also, pull requests are welcome :)

I know how to parse the string line by line and create new

to do this with a lazy result range and new allocations.
This isn't tested, but this is my first thought:

foreach(str; testString.multiSlice([":","-",";"]))
writefln("Got: %s", str);

So we're at 1:1 now, I guess? :hover is pretty much mandatory. Website need to work without JS. What was Adams gripe with :hover? I can't see a problem with it, as long as clicking still works as it does now (for mobile).

I can't see a problem with it, as long as clicking still works as it does now (for mobile). I click on my URL bar and punch in "interesting-site.com". It loads and I move my mouse down to a link or text field that I actually want on the page and click... But as the mouse went down from the address bar to the site, I happened to pass over a hover menu. My click is now intercepted and I'm sent to some entirely different page. Really annoying. (My bank's website had a login right below a hover menu, they have fixed it recently, but for the longest time, I'd want to log in but accidentally be sent to the bank officers list instead!) Or, I'm trying to copy something from a hover element and the page size suddenly changes with it being there... which now puts my mouse pointer outside the hover, which causes it to disappear, which changes the page size again, and now I'm just lost. (A lot of web sites assume the page will be pixel-identical on all screens, but I disable web fonts, so your menus are often not exactly the same size on my screen...) Similarly, something near the edge of a hover can be really hard to click with shaky hands, or sometimes errant margins on hovers (you'd think debugging would catch this, but I see it on live sites too, including big ones like Facebook) mean mousing over the gap to get to a link causes the link to disappear! Really frustrating. I'd imagine it is even worse if you have poor dexterity in general, so there's the accessibility aspect too. There's also no such thing as hover on devices without a mouse, which used to be just fossils like me using our lynx browser, but now includes a large number of people on the touch screens (though I question how many of them are actually doing programming so I don't think we should optimize specifically for them, but sometimes new users will check out a language mentioned to them on such a device so we don't want to leave them completely out either.) Of course, a click fallback handles those people. But even when - especially when - I have a device that supports hover, I dislike it. Yeah, I can see why that is an annoyance. But there is ways around it, like using transition-delay:0.200s [1] (or some other time that's quite small, so it doesn't impact the user actually trying to look at the drop down menu). That will prevent any annoying issues arising from moving the mouse across the web page. I think the drop down list is completely worthless on dlang.org anyway. Things moving around are harder to locate than a static thing, your spacial memory leads you to the wrong place then. I'd rather have a single click bring you to an info page with the other links. The above solution doesn't solve this of course, as you just think having a drop-down is a bad design decision :) How else would you lay it out? I dont think you could put all the content in that top bar pre-expanded - so you'd have all the menus on the left as it is on the current site? [1] http://dabblet.com/gist/1498446

I think the left menu on the current site is of limited value too. It is really hard to find what I'm actually looking for. (The organization is weird. To me, "D reference" and "standard library" ought to be the same, for example, and why is bug tracker under community?) I'd prefer to simplify it to like 5 menu items, each of which leads to a new page that can further break it down, using the whole screen to lay it out. Really, one of my biggest worries with dlang.org isn't the color scheme, but rather I feel like everything is cramped and content takes a back seat to cramming it all in. That's not to say we need infinite whitespace like so many new sites, I just don't think everything needs to be on every page. Yeah, I really dislike the over use of whitespace in current trendy sites. And the constant scrolling down to view more info is annoying too (I know CSS z-layer animations are cool, but they dont need to be everywhere!!). Well, while the website is going under such tumultuous changes, is now not the time to fix all the above? Clean everything up and put everything under sane headings/sections etc?

There should be a public benchmark standard. No special functions. No special linker flags. Just the plain code and compilation process. That'll never work though. 'Just the plain code' to me isn't 'just the plain code' to you. Ideally, a Git repo somewhere with a lot of benchmarks that the community can edit and make better. Over time (assuming the repo becomes somewhat popular) all benchmarking programs will use each language to it's fullest - thus giving accurate, comparable results across the board.

In some circumstances, I can see something like that reminding the author of the function about some details, but it can only confuse anyone else. There is nothing I can do about this. Who makes these decisions? Can we change it to something useful? Also, I think the documentation for functions involving ranges needs more "for dummies" examples. Too many of those functions leave the reader not having a clue what to do after calling the function. I know how that can be fixed. I think that most of the problem is simply down to how the documentation looks. It's too dense. I think some whitespace and some color-coding will go a long way to making the function signatures better. bool isSameLength (Range1, Range2) // a grey color (Range1 r1, Range2 r2) // a blue if (isInputRange!Range1 && isInputRange!Range2 && !isInfinite!Range1 && !isInfinite!Range2); // same grey color as template args, to point out they're working on the template I think that would make all documentation much easier to glance over, and yet easy to read if you need to.
