Hi

in the example #3 (A.3) from http://www.omg.org/spec/MOFM2T/1.0/ document, there´s a snippet like this

[module class_header_gen /]
[template public class_header(c : Class) { int count = -1; } ]
[file (c.name +'.cpp', false)]
[trace(c.id() +'_header')]
// Bit vector #definies
[for(a : Attribute) | c.attribute) { count = count + 1; }]
#define [a.name/]_BIT [count/]
[/for]
(...)

Acceleo has support for such a construct?

I´ve tried something similar but it did not work. Is there any way to do something like this using acceleo?

TIA

Kenji

Hi Kenji,

Long story short, this example is syntactically wrong, as are a number of the 'examples' shown in the specification; see my full answer on http://www.eclipse.org/forums/index.php/m/65064/?srch=counter#msg_65064 .

If what you need is the iteration count, you can use the implicit variable "[i/]" within a for loop :

[for(a : Attribute | c.attribute)]
#define [a.name/]_BIT [i/]
[/for]

Hi Laurent

the implicit variable will work

Thanks a lot
