reloaded 0.1.0

ReloadeD

ReloadeD is a simple library for live code reloading based on dynamic libraries.

ReloadeD is on experimental stage and have been tested only on windows.

Show And Tell

ReloadeD works with a simple Host application, and a Client Library.

//HOST APPLICATION

struct Data
{
    int value;
}

void main()
{
    import reloaded : Reloaded;
    import std.stdio : writeln;

    Reloaded script;
    Data userdata;
    /*
    Load the library, and pass the data that will be shared between HOST and CLIENT.
    */
    script.load("path/lib.dll", userdata );

    /*
    update() will call the method with same name at the client side and will reload the library when it changes automatically(and will call load()/unload() when necessary).
    */

    while(true)
    {
        script.update();
        //see the data changed by the client here
        writeln(data);
    }
}

The client can be used with 5 functions:

void init(void*) and void uninit(void*)

Will be called on the first lib load and when the host is destroyed(or you change the lib path). It receive the userdata;

void load(void*) and void unload(void*)

Will be called once every time the client changes. It receive the userdata;

void update()

Can be called at will on the host side (normally inside a loop).

ReloadeD will continue to work even if you don´t declare all possible functions.

Note that you don´t need Reloaded module on the client side so you can reload dynamic libraries from any language :)

//CLIENT LIBRARY

import core.sys.windows.dll;
import core.stdc.stdio : printf;
mixin SimpleDllMain;

extern(C):
nothrow:

//Same struct declared on Host
struct Data
{
    int x;
    int y;
}

Data* userdata;

void load( void* _userdata )
{
    printf("load\n");
    //capture data coming from Host.
    userdata = cast(Data*) _userdata;
}
void unload(void* userdata){
    printf("unload\n");
}
void init(void* userdata){
    printf("init\n");
}
void uninit(void* userdata){
    printf("uninit\n");
}
void update()
{
    //change value here, recompile and see the changes on the host side :)
    userdata.value = 10;
}

Reloaded was inspired by cr.h.
