radare2 is implemented on top of a bunch of libraries, almost every of those libraries support plugins to extend the capabilities of the library or add support for different targets.

This section aims to explain what are the plugins, how to write them and use them

Types of plugins

$ ls libr/*/p | grep : | awk -F / '{ print $2 }'
anal      # analysis plugins
asm       # assembler/disassembler plugins
bin       # binary format parsing plugins
bp        # breakpoint plugins
core      # core plugins (implement new commands)
crypto    # encrypt/decrypt/hash/...
debug     # debugger backends
egg       # shellcode encoders, etc
fs        # filesystems and partition tables
io        # io plugins
lang      # embedded scripting languages
parse     # disassembler parsing plugins
reg       # arch register logic

Listing plugins

Some r2 tools have the -L flag to list all the plugins associated to the functionality.

rasm2 -L    # list asm plugins
r2 -L       # list io plugins
rabin2 -L   # list bin plugins
rahash2 -L  # list hash/crypto/encoding plugins

There are more plugins in r2land, we can list them from inside r2, and this is done by using the L suffix.

Those are some of the commands:

L          # list core plugins
iL         # list bin plugins
dL         # list debug plugins
mL         # list fs plugins
ph         # print support hash algoriths

But also using the ? value in the associated eval vars.

e asm.arch=?   # list assembler/disassembler plugins
e anal.arch=?  # list analysis plugins


Note there are some inconsistencies that most likely will be fixed in the future radare2 versions.
