how do I prevent null errors when using __traits(derivedMembers
Hello, I've been poking around with "__traits", and I came across a problem: whenever I run a code like this "__traits(derivedMembers,members[i]);" I inevitably find a member that has no derived members, and inevitably the compiler tells me that I have an error: "Error: argument has no members", how do I check if a member has derived elements or if it has other elements contained within it? the "members[i]" is an array of members retrieved from "__traits(allMembers, someModule);" I'm trying to map all elements of an unspecified module for auto-completion and suggestion purposes, and I was wondering if there was a simpler/better ways to do that. Thank you.

Glad to see someone is reporting issues with this binding so I can iron out the kinks. I want to give it more attention and add support for 5.2, it's just always been low on my priority list. Please post any further issues you find at the github issue tracker [1], if you don't mind. [1] https://github.com/DerelictOrg/DerelictAllegro5/issues Thank you, if I find any new bugs I will report them to the github issues, So far I haven't found any new bugs. I will be testing other libraries (sdl, allegro, sfml, etc) because I'm reviewing several libraries to decide which I like best.

I forgot to 'git push --tags'. Once the dub registry picks it up, 0.0.5 should work. Thank you, initially It compiled, but then another error showed up, don't worry, Is not difficult to solve, and probably this has nothing to do with allegro. First it compiled (because I had not loaded any allegro library nor added any allegro code to my allegrotest project), whenever I tried to load the library "DerelictAllegro5.load();" the error showed up. But I know exactly what th problem is. The first library that dub looks for is called: "liballegro_image-5.0.11.so", but in my system (Arch repository allegro package) allegro's library is called:"liballegro_image.so.5.0.11" the difference lies in the extension ".so" that comes first, the version comes latter in arch. here is the error: «Linking...

Never mind, I used version 0.0.3, now works. Thank you.

Dub and derelict-allegro5 "Could not find a valid dependency tree configuration"
Hello, Every time I try to run a project with derelict-allegro5 package as a dependency, dub says: "Could not find a valid dependency tree configuration" I already cleaned the dub cache, that does not solve it, allegro package is installed (from alleg.sourceforge.net). dub works with derelict-SDL, etc. Thank you.
Re: SDL Error: identifier expected following '.', not 'version'
Thanks!
SDL Error: identifier expected following '.', not 'version'
Hello,
whenever I try to compile this chunk of code:
[code]
SDL_SysWMinfo info;
SDL_VERSION();
if(SDL_GetWindowWMInfo(win,)) {
writeln(info.subsystem);
}
[/code]
this error shows up:
Error: identifier expected following '.', not 'version'
BTW, i'm following the SDL official documentation (written for
C): https://wiki.libsdl.org/SDL_GetWindowWMInfo
Derelict SDL is fine, I have compiled SDL code before.
I Know that the word "version" is reserved for D, but how do I
circumvent this issue?
