thanks! just what I needed, with some stumbling I managed to get
everything working as intended: using a pointer variable to save
an adres of a function, then dereferencing to use it.
Now I am wondering when to use the ** ?
for example I found this function over at

Are you going to add popups of the types as in the F# page I

Bye,
I should have read your post more carefully, the 'tagging' in the
code is not really what I am after, I want the file including the
documentation to just be a valid d file, does'nt mean however
that there aren't ways of solving the issue without such precise
tagging I guess

If possible, even in C, I would recommend using a 'function
pointer' for that. However, there are cases
so I am still very new to structs and and * adress and pointer
stuff, I have this basic code :
struct S {
int value = 0;
}
void func(S thing){
writeln(thing); //BFC52B44
thing.value = 100;
}
S guy = {value:200};
writeln(guy); //BFC52CCC
sorry could have quicker just googled it thanks!
ah so much cleaner then the mess I was almost into ;)
thanks
I would like to use json/or any other format for defining
behavior trees.
in that file format I can only use strings
currently I just use the symbol directly but I was wondering how
to 'find' them otherwise.
float EAT_FOOD_DECISION(Agent agent){
return 1.0 - agent.hunger;
}
bool

Is that possible somehow?
If all your functions had the same signature, you could use an
associative array
I wasn't too happy about it and I wrote my own little parse
thingie and have a literate version nice and meta and small and
sloppy ;)

I am trying top port this code :
float interpolate( float from, float to, float amount, float
(*easing)(float) )
{
return from + ( to-from )*( easing( amount ) );
}
float linear_interpolation( float p )
{
return p;
}
the float (*easing)(float) part needs to be rewritten as
float
thanks, that worked, I need to grow a feeling for those * and
I've been googling without luck, is there a way to do literate
programming in D?, similar to how it's done in Coffeescript ?
http://www.coffeescriptlove.com/2013/02/literate-coffeescript.html
basically me writing comments around code and some parser that
creates styled documents from that
Aha, then It's quite safe to assume it won't be coming back I
guess, then I might need to cook up some homebrew alternative.
thanks for the info
That would work very fine, thanks sir!
I come from languages that don't offer structs, I have this json
load function that has to keep some data and intuitively I've
written a struct, I've read about the differences, heap vs stack,
value vs reference, but know I think i am overthinking it.
Is this decent:
bool loadFromFile
I am learning SDL by following the lazyfoo SDL2 tuorials, I am
alos new to D so I have a question:
I the lazyfoo tutorials there are many functions that have a bool
success whiich gets set at various places when something goes
wrong to be returned afterwards.
Oops well writing the above post made me realise what to look for

I want to learn SDL2 and learn D at the same time, for the SDL2
part autocompletion would be very nice.
I've found DCD but can't get it working (not finding symbols or
declarations) at the moment but I was wondering if there are any
alternatives, it's hard to google for d things and emacs,
edit : btw, I understand how to build an app that conscists out
of a few source files, I'd just do 'dmd file1.d file2.d' I
amtalking here about the situation where that's unpractical
because of the amount and folder structure.
Hello, I am completely new to D and have been paying around with
the tutorials, some docs and little test programs.
Now I want to try and use https://github.com/elvisxzhou/artemisd
for little gamedev experiment but I am running into build issues.
That project doesn't have a Makefile in the repo,
What issues have you had with rdmd?
The library seems to have a package.json file, so you could
also try dub:

what did the -Isource do? it's not in the 'rdmd --help'

You'll find it in dmd's
The switch itself is -I, not -Ipath. 'path' indicates a
parameter for which you need to substitute something, in this
case a directory path. It should be the root folder for the
source modules you want to add to the search path. In this
case, for artemisd, the source files are in the
29 matches
