Dear All,
I need to fill a lua table with data, and some values may be tables.
How to supply that data from ConTeXt?
The most straightforward way is to make user fill a string with lua code
of table initiaiser and then use "loadstring".
In this case the syntax is laconic, but resilence in case of errors is zero.
The other way is to have the user to call series of functions, building
the complex structure from ground up by making basic stuctures and adding
them to final structure one by one. In this case the passed parameters can
be scrutinized for correctness, but multiple calls like "addsmthtosmth",
"setsmthinsmth" will make the result uneasy to read, to say nothing of
writing.
What is considered kosher in ConTeXt?
Where can I found examples?
Sincerely, Michail
PS. data that has to be passed to function will look like (example is not lua):
--------------
name = "3D surface";
toolbar = TRUE; // display 3D toolbar
tree = TRUE; // display model tree
views = (
{
name = "DefaultView"; // first view (default)
projection = {
perspective = TRUE; // Perspective projection
aac = 2.5; // View angle
};
camera = { // Camera position, see movie15 manual
for explaination
coo = [ 0, 0, 0 ]; // Center of orbit - where the camera
are pointed to
c2c = [ 0, 0, 1 ]; // vector from coo directed to camera
rot = [40, 0,60 ]; // rotatations of vector from coo
directed to camera around Ox, Oy, Oz
roo = 50; // distance from coo to camera
roll = 0; // camera rotation angle
};
bg = [ 1.0, 1.0, 1.0 ]; // Background color
lights = "CAD"; // Lighting scheme
nodes = ( ( "xlabel", 1.0, TRUE ), ( "ylabel", 1.0, TRUE ), ("Small
box", 1.0, TRUE) );
},
{
name = "CrossView"; // view with a crossection
projection = {
perspective = TRUE; // Perspective projection
aac = 2.5; // View angle
};
camera = { // Camera position, see movie15 manual
for explaination
coo = [ 0, 0, 0 ]; // Center of orbit - where the camera
are pointed to
c2c = [-1,-1, 0 ]; // vector from coo directed to camera
roo = 50; // distance from coo to camera
roll = 0; // camera rotation angle
crossection = {
point = [ 0, 0, 0 ];
normal = [ -1, -1, -1 ];
intersection = TRUE;
transparent = FALSE;
};
bg = [ 1.0, 1.0, 1.0 ]; // Background color
lights = "CAD"; // Lighting scheme
nodes = ( ( "xlabel", 1.0, TRUE ), ( "ylabel", 1.0, TRUE ), ("Small
box", 1.0, TRUE) );
}
}
