Re: Explicitly Freeing Memory
Unfortunately I don't have any good suggestions... I have been avoiding depending on dtors in D because of the aforementioned issues (and more), so I haven't had much experience in debugging dtor-related problems in D. I decided to just free everything explicitly: https://github.com/maximecb/Higgs/blob/03931178deb5794bf27b1020542d102a08286c07/source/runtime/vm.d#L784 It seems to address my memory leak issue for the moment: `make test` uses about 1/3 the memory and runs more than twice as fast.
Dub / Derelict confusion
I would like to create a simple program using SDL. I've read this
page http://dblog.aldacron.net/derelict-help/using-derelict/ and
this one http://code.dlang.org/about and decided that using 'dub'
would be the sensible option for a beginner so I downloaded the
dub executable and put it in the same directory as my source file
'test.d'.
As per the example at the above url, I created a dub.json file in
the same directory with contents as so:
dependencies: {
derelict-sdl2:~1.0.0,
derelict-gl3:~master,
}
If I have the relevant import statements in test.d, am I right in
thinking I can use dub to build my program (not just download and
build the derelict libraries)? The command dub build test.d gives
me a 'failed to load package' error.
I'm using 32 bit Linux.
Any help appreciated :D

Dub will download and build the D packages from code.dlang.org.
However, some D packages require you to download compiled
libraries they link to for your syste. (or build them yourself
from source)
For sdl2 on linux, you need to go to:
https://www.libsdl.org/download-2.0.php and download the source.
Compile those libs using ($ ./configure; make; make install;)
Put them into a place your linker can find (usually /usr/lib/
iirc).
I believe that should work for you!
Re: Explicitly Freeing Memory
You can control it by creating a global flag and checking it before freeing.

could you give some more details? Full package.json, the
file-structure of your project and the full output from dub would
help.

You shouldn't be depending on ~master for anything anymore. The newest
version of dub will complain about dependencies on git branches. For
derelict-gl3, you can use =1.0.0.

Yes, assuming that your dub.json is properly configured.
The command dub build test.d gives me a 'failed
to load package' error.
That's the right command, but the wrong parameters. If you are going to
pass a parameter to the build command, it should be the name of a dub
package, not the name of a file. Typically, you don't need to pass it a
package name if all is properly configured.
Try this:
1 -- make sure dub is on the global path.
2 --
mkdir dubtest
cd dubtest
dub init
You should see the following output in side the dubtest dir
-dub.json
---source
-app.d
3 --
Edit dub.json and add the following dependencies:
derelict-sdl2:~1.0.0,
derelict-gl3:=1.0.0
4 --
Edit app.d to look like this:
import derelict.opengl3.gl3,
derelict.sdl2.sdl;
void main()
{
DerelictGL3.load();
DerelictSDL2.load();
import std.stdio : writeln;
writeln( Success!);
}
5--
Execute the following command:
dub
You'll see some messages about fetching and building the Derelict
packages and then, assuming you have SDL2 and OpenGL on your system
library search path, you should see it print Success!. Otherwise,
you'll get a DerelictException of one kind or another.
Note that I didn't give dub a command option. Executing 'dub' with no
options will cause it to build and run whatever package is in the
current directory. By default, dub will look for source/app.d if you
don't configure something differently in dub.json.
Executing 'dub build' will build the executable, but will not run it.
Re: Dub / Derelict confusion
Put them into a place your linker can find (usually /usr/lib/ iirc). I forgot, I'm pretty sure make install does that step for you.
Re: Dub / Derelict confusion
@wobbles:
Sorry, should have said, I built SDL and the libraries are

@John Colvin
The entire contents of dub.json are as above. My program is a
single file just to check that I can init SDL:
import std.stdio;
import derelict.sdl2.sdl;
void main(){
// Load the SDL 2 library.
DerelictSDL2.load();
//init SDL
.
}
The error is:
Error executing command build: Failed to load package at
/home/paul/D-programs/: Expected end of string after JSON value,
not ': {
derelict-sdl2:~1.0.0,
derelict-gl3:~master,
}'.

your dub.json is invalid. Please see
http://code.dlang.org/package-format
I'm not sure what the exact requirements are for a minimal
dub.json, but you should at very least have a name. Also, watch
out for where your source files are: dub expects them in a
source/ or src/ folder by default, you can change this by setting
sourcePaths in your dub.json

Thank you Mike, that works perfectly and pretty easy when you
know how - something else that is making D feel very comfortable!
For anyone else reading this... app.d is in the /source directory
created after executing 'dub init' and 'dub' or 'dub build' needs
to be run from the project file (the directory containing the
dub.json file and /source subdirectory). Both pretty obvious but
just in case ;)
Thanks John, your tip about dub.json noted!

Re: help
You need to check if remote file exist of server and only after it download шею Also add scope or try catch block to your code.
