Quote: Slammer,
I have a couple suggestions for features:
1. Allow the ability to access variables from user-defined structures by index.
That way we can pass in a List or HashTable containing UDS's to a function and apply an action based on the variable's index rather than the name, which could be different for each UDS.
Great for library building.
2. Call an external JAVA program, passing in Strings, Floats, Integers, Lists & HashTables with UDS's and return the same back into KickAssembler variables.
I could get the functionality by having my JAVA code generate KickAssembler script but this could get quite large for Collections.
Would be nice to have this inline.

1. Yep, I guess it's easily done. Im not sure i understand how to benefit from this in libraries. (Looking forward too see en example of use!)
2. Yep, can be done. Is in fact on the todo list, but it's will take a bit of work so i have postphoned it a bit. One of the reasons for restructuring the assemble mekanism so it could handle a flexible number of passes and to cache script results, was to be able to call external programs - Both with script parameters and assembled code (if you want to do crunching or encrypting etc.) |

Say I had a multi-field sorting routine this time for point{x,y} I could pass in a List of points.
Another time the names could be different or sort by even more fields.
I recently did a 2 field sort with a Hashtable and Lists. The Keys been the Y values which I called sort on, then called sort on Lists (Hashtable values).
That got me the result I wanted but I'd rather have a more generic solution.
But if suggestion #2 comes soon this will be irrelevant as I will just use full blown JAVA Collections and its interfaces (hmm still indexed fields would still be useful there saves
calling invoke on named methods).
And great to hear that it is on your list. That will make any other 'missing' functionality just go away. Cant wait! |

I don't think #2 will come that soon. Im pretty busy at the moment so there is not much time for coding for fun. However #1 is a small task. I guess it will be in the next release. |

Thanks Slammer that will help heaps.
So tempted to work the other way around and make JAVA spit out Kick Assembler script and ASM, but then I live in JAVA world all day.

Ive asked this once before, and found some workaround at the time that Ive forgotten, but I lost my kickass libs and had to revert to ca65 again - and now, once again, Im converting to kickass ;)
So... the question once again - if I have a macro, how do I tell if the parameters were passed or not? ie, can I implement nonmandatory parameters?
thanks

Hi Style
Normal macros have to have the right number of arguments.
Pseudocommands can have empty parameters |

any chance you can overload macros? :)

No, not at the moment.
Supplying too few parameters for a macros (like you can on pseudocommands) and setting the parameter to null when left out is possible. I left it out to avoid too much confusion when users supply to few arguments by mistake (Clearer errror messages vs flexibility) - If flexibility is in great demand, i'll open up that feature.
Since its a weakly typed script language something like the following is kind of against that nature of the language:
.macro myMacro(NumberValue x) {
//do something
}
.macro myMacro(String x) {
//do something else
}
If people miss this(?), it can be made possible by a type() function on objects:
.macro myMacro(x) {
if (x.type()==NUMBERVALUE) :myMacro_value()
else (x.type()==STRING) :myMacro_string()
else .error("Unkown Type")
.macro myMacro_value(x) {
//do something
}
.macro myMacro_string(x) {
//do something else
}
Btw. Can you give an example of where you will use this feature. |

yeh, on ca65 I had a macro, next_irq, which accepted conditional parameters of the address and raster position. If you didnt provide them, it merely dec $d019 (ie, there is only 1 IRQ)....
small point I know, but like I said Im trying to convert sources over the kickass.
