Code::Blocks - Symbol View
I've installed the last version (12.11) but I see nothing inside the symbol view. What wrong? If I press "Ctrl + Alt + G" I get often the message that no functions could be parsed, or in some other files I see only a few of them. Can I improve this?

I am also working on D and did not find it as a supported language. I'm not particularly interested in one written in D as much as for D. I would think lobbying/helping the drone.io team or one of the others include D as a supported language would be doable. Or if there is another system that D users are using? Further, IMHO having many of the dub packages set up to run tests and display a *passing* badge would give a positive signal.
Re: drone.io for D
That is weird. I have used some common CI platforms like Jenkins for D projects with no issues. Those are simply irrelevant to actual language used. There must be something I am missing. Can you give quick summary what drone.io is actually about? It is not clear from their web site and I don't like to watch promo videos.
core/sys/windows/windows.d is executable
Hello all, While updating my DMD/druntime/phobos install from git HEAD, I noticed that the druntime file core/sys/windows/windows.d has executable permissions. Am I right to assume this is a mistake which probably stems from someone editing it _on Windows_, from whence all files seem to arrive on POSIX with executable permissions? I'll file a bug report & patch, but first thought I'd check I wasn't mistaken about this being a mistake. Thanks & best wishes, -- Joe

But for Dart I have a github repository containing a package with a bunch of tests that succeed. I go to drone and create a project.

A small script drives the *test* which is usually just something that runs calls out to your test scripts. The language you select allows the build to know what to do after cloning your repository before calling your test. So for the case of dart, it shows the version of dart being used (which they keep as the latest version), then it does a *pub install* which installs all your Dart package requirements, then it runs your tests. If they pass your badge, which is a link to the status of the latest build is green. Here is a sample badge for a json schema validator: https://drone.io/github.com/patefacio/json_schema/latest The nice thing is, any time you commit to github a build is automatically kicked off and you get notification of success/failure. I think the setup would work well with the right prereqs on the box and with dub replacing pub for installing dependencies. Maybe others are using something else - like Jenkins? It looks like julia has a fair amount of this done with Travis. So what does/should D users reach for?

For example, I am hosting Jenkins-based suite for Volt developers: https://jenkins.dicebot.lv Regarding CI as a public service, it still should be possible to use it with D if it supports job dependencies and has basic C/C++ tools available. You can always define build dmd/phobos job and make your project depend on it, with tiny bit of include path tweaking. That may be much more cumbersome than you want though. There are also some plans for doing automated CI for all projects located in dub registry. I have recently discussed this with Sonke (dub author) and going to try that at least with Linux build slave. Prototype may be available by the end of the autumn (rough terms). This is still not exactly dart.io though Easiest way here may be to simply convience https://travis-ci.org/ guys to add native D support - but I don't know how to approach them :)
Re: drone.io for D
P.S. all the github integration you are speaking about is pretty common among all CI software I am aware of, so it should be mostly hosting/environment issue for you.

Re: Regex matching cause lots of _d_arrayliteralTX calls
27-Sep-2013 02:00, JR пишет: I'm working on a toy IRC bot. Much of the logic involved is translating the incoming raw IRC string into something that makes sense (so now I have two problems, etc). But I managed to cook up a regex that so far seems to work well. Time for callgrind! Grouped by source file, most time is spent in regex.d (as would seem natural) but more time is spent in gc.d than I would have expected. Looking at the callgraph I see that there's a curious amount of calls to _d_arrayliteralTX from (around) where the regex matching is done. (There's some inlining going on.)

It does do that, yes. But the semantics aren't *quite* what one might
expect (I was a victim of this misconception too :-P). What it does is
to, in effect, "copy-n-paste" the value of the enum into whatever code
uses it, every time. That means that if you write:
enum x = "abc";
void fun() { auto y = x; }
void gun() { auto z = x; }
It will *copy* "abc" into y and z (rather than just aliasing the same
underlying string), *each time* you call fun() and gun().
TL;DR: use immutable instead of enum for array-based constants:
immutable x = "abc";
void fun() { auto y = x; } // now y is just an alias of x
void gun() { auto z = x; } // now z is just an alias of x

I've recently investigated similar problem w.r.t. performance of std.regex on particular use-case/pattern. In fact it dig up an interesting bug with inlining in the compiler along the way. It took about 5 minutes to test that enum used instead of static devastates performance but quite some time to figure out the actual "infection chain".

No, it should not be executable. The only time that it makes sense for a .d file to be executable is when it's a script with something like #!/bin/rdmd at the top, which certainly isn't the case for windows.d. - Jonathan M Davis

(I was of the notion that that enum merely translate to

It does do that, yes. But the semantics aren't *quite* what one
might
expect (I was a victim of this misconception too :-P). What it
does is
to, in effect, "copy-n-paste" the value of the enum into
whatever code
uses it, every time. That means that if you write:
enum x = "abc";
void fun() { auto y = x; }
void gun() { auto z = x; }
It will *copy* "abc" into y and z (rather than just aliasing
the same
underlying string), *each time* you call fun() and gun().
I think strings are an actual exception to this rule, what with
being immutable and all (provided you place the info in a string
of course "char[] ss = s" will allocate of course).
All other types, even immutable (AFAIK) will allocate though, yes.
ieeeFlags are not getting set.
Hi everyone,
I am new to the D programming language and decided to use it for
simple assignment. The idea is to compute the product of an
arbitrary number of numbers and print the result in a specific
way. The program needs to handle underflow/overflow, thus I
decided to use ieeeFlags. The program is found below.
Basically, the flags are not getting set. Changing the the
if-statements to check whether the resulting value is infinity or
0 (to test respectively for overflow/underflow) and it works. So
I am starting to think either I don't understand how this work,
or there is a bug.

Is there any particular reason to use "0.0.0.0" creating your
InternetAddress? I think it should be the ip of your server
or just send port and ADDR_ANY will be used.

I thought ADDR_ANY is the same as "0.0.0.0",so I used it.
