auto seismodownload = new seismoDownload(emsc_csem, this);
then:
auto mysql = new MySQL(parseconfig,eqs);
So could anybody show me better way? As I said I did not fully
understand how use global class instance...
I looked at my code and it's seems that I can create instance of
MySQL in main.
void main()
{
auto parseconfig = new parseConfig();
auto mysql = new MySQL(parseconfig, seismodownload);
}
In parseConfig I am creation instance of seismoDownload:

Well, there's no `parseconfig` there. Do you expect the

170?

If I right understand scope is not good for checking if one of
function is fail.
For example:
string dbpass = config.getKey(dbpass);
string dbpass = config.getKey(dbpass);
string dbhost = config.getKey(dbhost);
string dbport = config.getKey(dbport);
if I will try to add scope(failure)
I reread docs and understood that scope not for such case.
Next code is do what I need:
try
{
string dbname = config.getKey(dbname);
string dbpass = config.getKey(dbpass);
string dbhost = config.getKey(dbhost);
string dbport = config.getKey(dbport);

connect() sends a CONNECT request to the server, as defined
by HTTP [1]. This method is only used when you're working with
proxies and the like. What you most likely want, however, is a
GET request. Use get() for that.
So what is the best way to check status server response (400, 404
etc)
Big thanks Ali!
Only the small last question:
why:
string link = dlang.org;
writeln(connect(link));
cause crash:

.d(779): HTTP request returned status code 400
0x00404263
My guess is that you have to use HTTPS for CONNECT and that you
have to have credentials for it. (?)
Ali
dlang.org should work on HTTP, but not HTTPS.
Also I do not think that when I connect to HTTPS I should have
any credentials. It's mostly like issue with curl...
Could anybody explain why there is opinion that stack is fast and
the heap is slow. All of them are located in the same memory. So

I can't understand why I am getting exception on next code:

Am I right understand all exception are derived from
assertThrown
http://dlang.org/phobos/std_exception.html
So msg in catch(Exception msg) is from function
assertThrown?
Could you show me example of how to handle type of exception?

ah, that's it! as spec says, D determines function return value

so function return type is determined to be `void`.

It's look like collision was with method name.
Sometimes it's path string may do not have tail slash of the path
Compare:

in case if I need to append file name to path to get full path I
can get error like:

see std.path, it contains alot of useful things.
I looked there, but found only buildNormalizedPath, but it's not

take a second look then. ;-) you'll find `buildPath()` here too.
Not better:

writeln(foo);
foo = foo.buildPath;
foo ~= config.txt;

Ali Çehreli, could you add this mention and possible the example

I know that a lot of people are using for programming tools like
Sublime. I am one of them. But if for very simple code it's ok,
how to write hard code?
Do you often need debugger when you are writing code? For which
tasks debugger are more needed for you?
We have to look at the documentation of the function. In this
case the possibilities are FileException and UTFException.
http://dlang.org/phobos/std_file.html#.readText
However, judging by their names, they are both descendants of
Exception, so what you are doing will catch either of them.
void openFile(string fname, string current_folder)
{
auto file = readText(current_folder ~ fname);
scope(failure)
{
writeln(failure);
}
// writeln(file);
}
if file name do not exists, I want to rise scope exception. But
it's do not rise,
I can't understand what I am missing. Try-catch block also do not
handle exception:
void main()
{
string fname = app.d1; //file name with error
string current_folder = (getcwd() ~\\);
writeln(current_folder);
openFile(fname, current_folder);
}

Am I right understand that keyword Exception is handle
universal type of exceptions?
catch (Exception)
{
writeln(inner);
}
But in my example with try block can I change it's to something
more informative?
Replace that with something like writeln(caught) and you will
see that it is indeed caught. :) Printing the exception mimicks
the default behavior and you (and I) think that the exception
is not caught. :)
that's work, but I can not understand where I can to look at
exception level. If I

Thanks! In which cases tuples can be helpful?

2. How ti expend tuple? I tried to do:

imglist.expand[sss];
Is it's possible to create single language that cover desktop and
web? Like D+Dart?
I ask becouse I can't understand why it's need 2 language if they
are very simmiler and it's can be 1 language instead 2.
I know that there is way to write all on JS. But I can't
understand what the reason that there are no single language that
can work on web and as native language.
It is possible, but you need to design the language within the
constraints of javascript:
1. single threaded (or worker threads)
2. 53 bits integers, 26 bits for multiplies.
4. weird fixed size heaps (ArrayView)
5. if garbage collection then it has to be javascript style
6. no tricks:
No! I mean not translation to js. I mean theoretical ability of
creation new programming language that can work every where!
