Then i suggest you use pseudo commands. Here is an example of how to do:
// Use it like this
:irqEnd #$60 ; #irq2
// The macro
.pseudocommand irqEnd nextIrqYpos ; nextIrq ; extraArg {
.if (nextIrqYpos.getType()!=AT_NONE) {
:mov nextIrqYpos ; $d012
}
.if (nextIrq.getType()!=AT_NONE) {
:mov16 nextIrq ; $fffe
}
.if (SAVE01==extraArg.getValue()) {
:mov _ds_irq01 ; $01
}
lda _ds_irqa
ldx _ds_irqx
ldy _ds_irqy
rti
}
The above have optional parameters for next ypos, next irq address, and an option to save $01. (The mov commands are 'pc style' pseudo commands that moves data) |

Conjuror: Finally found some time to make a new release. Made the following functions on user defined structs:
getStructName() - returns the structure name
getNoOfFields() - returns the number of defined fields
getFieldNames() - returns a list of field names
get(fieldName) - returns a field value by field name.
get(index) - returns a field value by field index
set(index, value) - sets a field by field name
set(fieldName, value) - sets a fields by field index

Slammer,
Great work! thanks. This will really help with more flexible code creation.
Nice to see the ternary operator in there too.

Hey ppl! I have a newbie question: is there a way to use constants inside a macro?
For instance, I need to be able to do something like this:
.const MyConst = $d012
.macro myMacro(val)
{
ldy #val
sty MyConst
}
But I get an error when compiling.
Thanks in advance! :) |

Constants are visible after you have defined them. So the example you give, will work if you declare your const before you use the macro:
:MyMacro($32) // This won't work
.const MyConst = $d012
:MyMacro($32) // This will work
.macro myMacro(val)
{
ldy #val
sty MyConst
}
However, labels can be seen in the whole scope so they can be used before they are declared:
:MyMacro($32) // This will work
.label MyLabel = $d012
.macro myMacro(val)
{
ldy #val
sty MyLabel
} |

Thanks for your help!
I think i'm declaring the constant before using the macro but i'm still getting the compiler error.
I have two separate files. One called system.asm and the other test.asm.
// System.asm
.const MyConst = $d012
.macro myMacro(val)
{
ldy #val
sty MyConst
}
Then in the test.asm:
// test.asm
.import source "system.asm"
// some code
:myMacro(0)

I Just tried it and it works fine here. My guess is that you define the macro+constant inside one scope and execute your macro outside the scope. Eg. if you start you system.asm file with a .filenamespace directive.

How would I go about doing a:
.fill 256,invert(data.get(i))
i.e. invert the data filled into memory on the fly? |

Suppose by invert you mean exclusive or you can:
.fill 256,data.get(i)^$ff |
| Previous - 1 | ... | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | ... | 61 - Next |
