I've been using cmdLineVars in order to inject global constants, e.g. "debug", and some macros / functions to support this:
.function isDebug() {
.return cmdLineVars.get("debug") != null && cmdLineVars.get("debug").asBoolean()
}
.pseudocommand debugD020 {
.if (isDebug()){
inc $d020
}
}
.pseudocommand rebugD020 {
.if(isDebug()){
dec $d020
}
}
Works like intended, and I can surround debug code with isDebug() or use debugD020 without worrying where the debug-symbol is defined.
But it is a little quirky having to declare ":debug=true" on the commandline. I would rather see something similar to Java's "final static" in addition to the cmdlineVars hash.
Also, vars, consts and friends should respect the namespace they are declared in.
@Cruzer:
What about
block: {
label:
.if (true) {
nop
}
}
jmp block.label

"Can I see the code contructs you are using? Is it labels or options you are setting up this way?"
both. i use conditional assembling with labels inside if/then a lot, and also headers with defines that are switched for different configurations. and i honestly dont feel like showing more code just to see another proposed super ugly workaround as a response =)
"So send me an example of 'ugly code' and preparsing will be taken into consideration."
if whats shown in this thread doesnt already convince you, then all hope is lost - forget it. maybe kickass is for tables and not for code =P
"vars, consts and friends should respect the namespace they are declared in."
yes. and it should be possible to explicitly export them into the parent namespace. thats how any other sane assembler does it anyways =P |

So Mads, I've got one question:
Question: Before I go ahead and make too many pseudocommands, is there any plans for implementing the 65816 OPC set? |

TWW: The short answer is no. I'm considering doing a hand made lexer/parser which allows people to insert their own instruction sets (from whatever processor you wish) while reusing the script language. This will take some time, so earliest release date (if any) will be about a year from now. So if I were you I would just go ahead with the pseudo-commands. |

Fair enough. You've done very well to suply the sceene with this tool never the less. And hey, it's not that long to christmas ;-)
I have a question regarding pseudo-cmds (again):
.pseudocommand STZ val {
.if (val.getType()==AT_ABSOLUTE) {
// .if (val.getValue()<256) {
// .byte $64, <val.getValue() // Stupid ZP fix
// } else {
.byte $9c, <val.getValue(), >val.getValue()
// }
}
.if (val.getType()==AT_ABSOLUTEX) {
.byte $9e, <val.getValue(), >val.getValue()
}
.if (val.getType()==AT_ZEROPAGE) { // The pseudo don't recognize ZP adressing...
.byte $64, <val.getValue()
}
}
When I call the routine with a :STZ $00 the result produced is absolute and not ZP. AbsoluteX works fine though. Am I doing something wrong? |

When getting an argument like $80, and yet not know in which command its used, you don't know what address mode going to be used. It could be absolute, relative or zeropage.
jmp $80 // Absolute
lda $80 // Zeropage
bne $80 // Relative So the most basic form, absolute, is passed around and its up to the commands to decide if a specialised form is going to be used instead.
You can see the addressmodes pseudocommands recieve in table 7.2 here:
