Currently it's possible to list possible variable values in the CLI with e search.in=?.
But in Ve visual configuration options navigator the feature is missing:

$ r2 -
[0x0000000]> Ve
[EvalSpace < Variables: search.align]
                                                                                                                                                                    

Is your feature request related to a problem? Please describe.

It'll be nice to have a hotkey (like H in IDA) to toggle the integer base between HEX and DEC. Since it may not work in Decompiler without backend support, having it in Disassembly/Graph will still be nice.

Describe the solution you'd like

So when I press the hotkey (maybe H if it's available), it should work like

Print the following workflow:

r2 -e io.va=false /bin/ls
[0x000068d0]> pfo elf64
[0x000068d0]> pf.elf_
pf.elf_ident    pf.elf_phdr     pf.elf_header   pf.elf_shdr     
[0x000068d0]> pf.elf_ident @ 0
   magic : 0x00000000 = "\x7fELF"
   class : 0x00000004 = class (enum elf_class) = 0x2 ; ELFCLASS64
    data : 0x00000005 = data (enum elf_data) = 0x1 ; ELFDATA2LSB
 version : 0x00000006 =

Currently, accessing Bindings in RadecoFunction is not elegant. We should improve support for this. This should also be extended to improve accessing of type and other node information related to these bindings.

• Python 2 support (ends in one year) - an probably all versions less than 3.4
• PHP5 (support just ended this year) - maybe porting to PHP7?
• Luvit support - 7 years no updates
• Newlisp - 7 years no updates
• Guile - 7 years no updates
• Awk - 6 years no updates (is anyone using them at all?)
