digitalmars.D.learn - Looking for instructions on how to make a Derelict library

Hey everyone,

I wanted to make a version of SQlite3 that uses Derelict to load 
the sqlite3 DLL when I'm ready. I can't find any instructions for 
how to make a basic Derelict style library. I looked around at 
http://derelictorg.github.io/, but could not find anything. Does 
anyone have any?

Thanks.

Just look at the existing Derelict packages. For a normal C 
library like sqlite3, it's pretty straightforward -- declare 
function pointers to ever public function in the API, translate 
all the types, convert any macros to D functions, and create a 
loader that extends derelict.util.SharedLibLoader and overrides 
loadSymbols. Examples: DerelictLua, DerelictODE, DerelictFT.

You can also add support for static bindings by versioning out 
the function declarations and the loader in favor or normal 
function declarations. Examples: DerelictSDL2, DerelictGLFW3, 
DerelictAL.

See the D wiki for links to articles that show how to translate C 
headers.

I've been reading the DerelictSDL2 source code. I think I have a 
handle on it. I'll have to look more at the wiki too.

Thanks.

Might be interesting to write up your experience with doing it as 
either blog post or part of the Derelict documentation (which is 
already quite good, IMO).

I used to have a guide to creating "Derelictified" bindings for 
an older version. I should write one up for the current version.

I was thinking of doing that. I'll have to figure out the best 
way to do that, once I get a better understanding of how Derelict 
works.
