The e?? command to get help on all the evaluable configuration variables of radare2. As long as the output of this command is pretty large you can combine it with the internal grep ~ to filter for what you are looking for:
The Visual mode has an eval browser that is accessible through the Vbe command.
Defines the target CPU architecture used for disassembling (pd, pD commands) and code analysis (a command). You can find the list of possible values by looking at the result of e asm.arch=? or rasm2 -L. It is quite simple to add new architectures for disassembling and analyzing code. There is an interface for that. For x86, it is used to attach a number of third-party disassembler engines, including GNU binutils, Udis86 and a few handmade ones.
Determines width in bits of registers for the current architecture. Supported values: 8, 16, 32, 64. Note that not all target architectures support all combinations for asm.bits.
Changes syntax flavor for disassembler between Intel and AT&T. At the moment, this setting affects Udis86 disassembler for Intel 32/Intel 64 targets only. Supported values are intel and att.
A boolean value to set the psuedo syntax in the disassembly. "False" indicates a native one, defined by the current architecture, "true" activates a pseudocode strings format. For example, it'll transform :
│ 0x080483ff e832000000 call 0x8048436
│ 0x08048404 31c0 xor eax, eax
│ 0x08048406 0205849a0408 add al, byte [0x8049a84]
│ 0x0804840c 83f800 cmp eax, 0
│ 0x0804840f 7405 je 0x8048416
to
│ 0x080483ff e832000000 0x8048436 ()
│ 0x08048404 31c0 eax = 0
│ 0x08048406 0205849a0408 al += byte [0x8049a84]
│ 0x0804840c 83f800 var = eax - 0
│ 0x0804840f 7405 if (!var) goto 0x8048416
It can be useful while disassembling obscure architectures.
Selects a target operating system of currently loaded binary. Usually, OS is automatically detected by rabin -rI. Yet, asm.os can be used to switch to a different syscall table employed by another OS.
If defined to "true", disassembler view will have flags column.
If set to "true", draw lines at the left of the disassemble output (pd, pD commands) to graphically represent control flow changes (jumps and calls) that are targeted inside current block. Also, see asm.lines.out.
