* Initial support for visual cursor with invert cons in 'pd' bytes - Some changes in '*' and '/' keys in visual modes (+-16) - '+/-' in visual cursor works as in r1 (inc/dec cursor byte) * Rename 'zf' into 'zh' for header, not function - 'zf' stands now for function signatures (args, types, ret, ...)
r_sign: signature api for radare2
=================================
Plugins are used to implement data collectors for r_sign.
A data collector is a piece of code that feeds the r_sign
database with information about symbols.
r_sign is configured to weight each attribute with some properties
to be able to determine the semblance between a collector source
information and the playground where r_sign tries to find valid
duplicates of the information stored previously following the
configured attributes and then we have output plugins to
Plugin types:
=============
collectors - collects initial signatures (libc, libm, ...) [ INPUT ]
playground - find collected info using the configured attributes [ INPUT ]
dumpers - dump the resulting information in ascii [ OUTPUT ]
- dump signature
- dump results of the signature analysis
Items in stored database
========================
Should contain something like:
// raw byte search //
typedef struct {
char *name;
ut8 *bytes;
int len;
RList hits;
} RSignItem;
We need some way to store other kind of properties for signature types..
r_sign_item_new ();
r_sign_item_add (sign, s_item);
Matchers should allow some ranges.. for example. we can accept two matching sequences with a distance of X
