Re: Using attributes inside template instantiation
But if I write
@("hello") struct Hello {}
so all of the variables that have type Hello will have attribute
@("hello") like come type qualifier because attribute is a part
of declaration of Hello. Do I understand correctly?

Hi, I'm using scriptlike, which imports everything from std.process for convienience, but I also need to import another module, which contains a class `Config`, it conflicts with std.process.Config. I don't actually need std.process.Config, but I need many other symbols in scriptlike and std.process. What I want to achieve is to import ALL symbols from scriptlike EXCEPT std.process.Config, something like: ```d import scriptlike: !Config; ``` or rename it AND import all other symbols, to resolve the confliction. ```d import scriptlike: *, Cfg = Config; ``` I don't know how to achieve these effects, selective import and rename seems to only import the one I specified.

Let me preface this by admitting that I'm not sure I'm using
the DDoc functionality properly at all, so let me know if my
questions are bogus.
Is it possible to:
- Add private members to documentation?
- Have DDoc do its thing after mixins have been handled?
- Access UDAs?
To expand on the last point: in my code I currently use UDAs
to annotate variables that can be set in an input file; at
compile time I use __traits to find all of them and create a
parser etc. for them. I would really like to be able to create
a minimal documentation, which only includes all such
UDA-annotated variables from all modules, so it can be used as
a short manual for the end user, rather than being developer
documentation. I was thinking of using a LaTeX template and
using the absence or presence of the UDA to somehow insert a
macro that is either just blank or actually adds the
documentation.
Any tips to achieve this in a different fashion are also
appreciated.
Kind regards,
Stefan Frijters
1) You might be interested by ddox [1] which provides more
functionality and a nicer output than DDoc (actually, the
phobos docs are being replacd by it).
As you can see in the example, you can filter what goes in and
what doesn't, as well as the minimum protection level (so you
can chose to put private in it).
Note that if you have a dub-based project, you can just run
"dub --build=ddox" to get it working.
2) Yes for regular mixin, no for template mixins. Example:
mixin strToSym!(moduleName!moduleName); // Template mixin
mixin("int a = 42;"); // regular mixin
Will output (using dmd -Xfdocs.json module.d):
{
"name" : "strToSym!(\"std.traits\")",
"kind" : "mixin",
"line" : 62
},
{
"name" : "a",
"kind" : "variable",
"protection" : "private",
"file" : "CppWrapper.d-mixin-63",
"line" : 63,
"deco" : "i",
"init" : "42"
},
3) Nope. Again, example:
@("ThisIsAFunction")
void foo() {}
Ouputs in the docs.json:
{
"name" : "foo",
"kind" : "function",
"protection" : "private",
"file" : "CppWrapper.d",
"line" : 66,
"deco" : "FZv",
"endline" : 66
},
Hope this helps !

I've done the same for my own programs:
class ExitException : Exception
{
int status;
this(int _status, string file=__FILE__,
size_t line=__LINE__)
{
super(file,line);
status = _status;
}
}
void exit(int status=0) {
throw new ExitException(status);
}
int main(string[] args) {
try {
...
return 0;
} catch(ExitException e) {
return e.status;
} catch(Exception e) {
... // real exception here
return 1;
}
}
It works reasonably well for single-threaded program, but as the
following bug states, there's no nice way to terminate a multithreaded
program:

Only the command shell can change it's own environment. When you execute
commands that set an environment variable, those are shell builtins, not
external programs.
You can run a batch file (which is not run in a separate process) which
sets environment variables. This may be the only way to affect the
environment. Basically, have a program run that dictates what to set,
builds a batch file, then run that batch file from the command line. This
could be done in another batch file.

Getting libcurl for 64 bit Windows
I am attempting to make use of std.net.curl and having trouble acquiring libcurl for 64 bit Windows. I need to be able to link with the MSVC linker (which happens to be the default when compiling using dmd with -m64). I've looked on the libcurl website and not found any downloads that look promising. I've tried following the instructions at: http://wiki.dlang.org/Curl_on_Windows#Building_libcurl_64_bit But when I compile the dll with: "dmd main.d -m64 -Llibcurl.dll" I get the linker error: libcurl.dll : fatal error LNK1107: invalid or corrupt file: cannot read at 0x330 Might anyone have an idea as to how to resolve this?
Re: Getting libcurl for 64 bit Windows
Managed to build it successfully I think, but have actually
returned to the problem that initially caused me to want to try
and build the library in the first place:
If I try to build a simple program:
import std.stdio;
import std.net.curl;
void main() {
writeln("Hello world");
}
The program compiles, but does not print Hello World at
runtime... it just stops, and seemingly does nothing.
Trying to determine the root cause of that now.

Does anyone have good instructions for building libcurl on Win64, or

Re: SList: How do I use linearRemove?
First case is a bug. I'll make pull request. Not sure about second.
Re: Getting libcurl for 64 bit Windows
Resolved the issue.
Re: Getting libcurl for 64 bit Windows
The one that the win64 auto-tester uses is here:
http://downloads.dlang.org/other/
curl-7.28.1-devel-rainer.win64.zip
There's a newer one available there, but I can't vouch for it.

Managed to build it successfully I think, but have actually
returned to the problem that initially caused me to want to try
and build the library in the first place:
If I try to build a simple program:
import std.stdio;
import std.net.curl;
void main() {
writeln("Hello world");
}
The program compiles, but does not print Hello World at
runtime... it just stops, and seemingly does nothing.
Trying to determine the root cause of that now.
Mark is my intern, and we're currently blocked by this in creating an important
demo for tomorrow.
Does anyone have good instructions for building libcurl on Win64, or prebuild
.lib and .dll files?
Thanks very much,

I'm currenly renaming my own symbol: ```d import scriptlike; import config : Cfg = Config; ``` Your solution works for me :-) Thanks

I don't actually need std.process.Config, but I need many other symbols in scriptlike and std.process. What I want to achieve is to import ALL symbols from scriptlike EXCEPT std.process.Config, something like: ```d import scriptlike: !Config; A similar idea is present in Haskell, but it was refused by Walter. Thanks :-) I wander what was the rationale behind Walter's rejection. IMHO if we have a selective filter mechanism for imports, the complement exclude mechinism works as well. But of cause we are not that far yet, final, nothrow, pure and others don't have their complements either. The use of scriptlike is going to cause you similar problems, it's not for a fine tuning of imports. The problem is that we don't have a complete mechanism to fine tuning the imports. Selective filtering is only half of the cake. Bye, bearophile

Enum type deduction inside templates is not working
Compiler can't deduce type for template struct Pair when using it
with enum argument. There is an example
import std.stdio;
enum Category { first, second, third };
struct Pair(F, S)
{
F first;
S second;
this(F f, S s)
{
first = f;
second = s;
}
}
void main()
{
auto p = Pair(Category.first, "first"); //It fails
writeln(p);
}
Is it not working for some reason or I'm doing something wrong or
is it just lack of implementation? How I could make this working
without explicit specifying of types?

is this a solution for your problem?
enum Category { first, second, third };
struct Pair
{
Category cat;
string second;
this(Category cat, string second){
this.cat = cat, this.second = second;
}
}
void main(){
auto p = Pair(Category.first, "first");

Maybe it was discussed already somewhere, but I am not god in searching in English. Is there any directions about it? How could I work around it? Should I mail some proposal or bug report for it?

It can be used in two ways:
1) When used as a unary operator, it means bitwise complement:
assert(~0xaa55aa55 == 0x55aa55aa);
2) When used as a binary operator, it means concatenation:
assert("hello" ~ " world" == "hello world");
auto arr = [ 1, 2 ];
assert(arr ~ 3 == [ 1, 2, 3 ]);
When used with assignment, it means appending:
auto arr = [ 1, 2 ];
arr ~= 3;
assert(arr == [ 1, 2, 3 ]);
It can also be used in the special function name ~this(), which is the
destructor of a struct or a class. (Related functions: 'static ~this()'
and 'shared static ~this()')

I think, D is a typesafe language, therefore you can't use
variables with no type declaration.
One thing you can search for, are templates but even there you
have to define a type:
import std.stdio;
enum Category : string { first = "first"}
template Pair(T)
{
T t;
T cat;
}
void main()
{
alias Pair!(string) a;
a.cat = Category.first;
a.t = "first";
writeln(a.cat, " . ", a.t);
}
