hexer (hex editor with vi-like UI)
|
||||
|
||||
Hexer is a multi-buffer editor for binary files for Unix-like systems
|
||||
that displays its buffer(s) as a hex dump. The user interface is kept
|
||||
similar to vi/ex.
|
||||
|
||||
If you don't like the default color scheme, copy one of the
|
||||
/usr/doc/$VERSION/rc/hexerrc.* files to ~/.hexerrc.
|
||||
|
||||
The package also includes myc, a simple textmode calculator that's
|
||||
useful for hex <=> decimal conversions and bitwise operations.
