[Scilab-users] ipcv vs scicv

[Chin Luh Tan]

Hi all,

Stephane, Thanks for the quick  examples to illustrate this.

Claus, as shown by Stephane, this could be now by ourselves now from our
own modules. Stephane has illustrated a quick demo on this, while the one I
was testing with is the copy of toolbox skeleton inside the Scilab contrib,
modified to 2 modules, installed with atoms and let it load at start,
results are the same.

There are 2 potential issues which we should take notes:
1. The module which is loaded last, will have the "dominant" in the base
function. for e.g.: the example that Stephane showed, we could call
"lib1.foo" and "lib2.foo", and calling just "foo" will be the same as
"lib2.foo".
2. Only macros function could be called this way, if a module has a scilab
gateway that called direct from Scilab, (such as scicv), you could not call
scicvlib.imread as the imread is directly expose from the C lib to Scilab.
So during the design of the module, you could have a macros wrapper to call
the gateway functions so that they could be listed in the library's macros
list.

Thanks.

rgds,
CL
