Pretty6502

Pretty6502 v0.8 by Oscar Toledo G. http://nanochess.org/

Usage: pretty6502 [args] input.asm output.asm

It's recommended to not use same output file as input, even if possible because there is a chance (0.0000001%) that you can DAMAGE YOUR SOURCE if Pretty6502 has undiscovered bugs.

Arguments: -s0 Code in four columns (default) label: mnemonic operand comment -s1 Code in three columns label: mnemonic+operand comment

-p0       Processor unknown.
-p1       Processor 6502 + DASM syntax (default)
-p2       Processor Z80 + tniASM syntax
-p3       Processor CP1610 + as1600 syntax (Intellivision)
-p4       Processor TMS9900 + xas99 syntax (TI-99/4A)
-p5       Processor 8086 + nasm syntax
-p6       Processor 65c02 + ca65 syntax
-p7       Processor 6502 + gasm80 syntax 
-p8       Processor Z80 + gasm80 syntax

-n4       Nesting spacing (can be any number
          of spaces or multiple of tab size)

-m8       Start of mnemonic column (default)
-o16      Start of operand column (default)
-c32      Start of comment column (default)

-t0       Use spaces to align (default)
-t8       Use tabs to reach column (size 8)
          Options -m, -o, -c, and -n must be multiples of this value.

-a0       Align comments to nearest column
-a1       Comments at line start are aligned
          to mnemonic (default)

-l        Put labels in its own line

-dl       Change directives to lowercase
-du       Change directives to uppercase
