I want template this code
if ( state & INIT && diraction = IN )
{
Label
text = "text"
}
if ( state & OPEN && diraction = OUT )
{
delete AppsWindow
state &= !OPEN
}
to
TPL( INIT, IN,
{
Label
text = "text"
}
)
TPL( OPEN, OUT,
{
delete AppsWindow
state &= !OPEN
}
)
Desctiption:
condition: "if ( state & OPEN && diraction = OUT )"
replace to template: "TPL( M, D )"
pass code block as argument.
Analog C-code with macros:
#define TPL(M,D,CODE) if ( state & OPEN && diraction = OUT )
CODE;
example code
TPL( OPEN, OUT,
{
delete AppsWindow
state &= !OPEN
}
)
It possible in D ?
How pass code block to template ?
How to solve this problem ?
