Suppress Function Evaluation

["O'Riain, Colm" <CORiain@...>]

My apologies if this has been covered recently on this list but I couldn’t find it in the archive.

 

I’m trying to pass a table containing functions as a parameter as follows:

 

local myTable =

{

            {‘hello’, nil, myFunc (3,4) },

            {‘not now’', nil, print(‘the end is nigh’) },

            {‘maybe later’, nil, anotherFunc(5,6) }

}

bigFunc(myTable);

 

where myFunc and anotherFunc are pre-declared functions and bigFunc is a function which _might_ call the 3^rd entry in each subTable in myTable. The problem is that on calling bigFunc, the 3^rd parameter of each subTable is always evaluated and the function is always called immediately, which is not desirable. Is there a way to suppress evaluation at call time or am I looking at this assways?

 

I’ve got around it by passing the function and its parameters in as a table

 

local myTable =

{

            {‘hello', nil, {myFunc,3,4 },

            {‘not now’', nil, {print,‘the end is nigh’} },

            …

}

bigFunc(myTable);

 

and then putting the function call together inside bigFunc but this feels like cheating given how flexible Lua is.

 

Thanks for any light you can throw on this
