[radare]

what about making varsum an int instead of bool and show different format depending on value?

also, there are conflicts in disasm.c can you rebase?

[giuscri]

Rebased.

@radare, you mean something like asm.varsum=0 for no summary, asm.varsum=1 for current variables summary and asm.varsum=2 for the view proposed in #9239?

Doesn't that have the disadvantage of breaking current radare2rc's?

[giuscri]

Added colored output.

Removed asm.varsum.altern, changed varsum into an integer (0, 1, 2).

Also this should not break .radare2rc's that use a boolean for asm.varsum, as asm.varsum=false|true will be interpreted respectively as 0 and 1.

Thanks!
