heme - console hex editor

heme [ -d, --disable-colors ] [ -c, --config-file CONFIGFILE ] [ -n, --no-backup-files ] [ -h, --help ] [ -v, --version ] file

heme is intended to be fast and portable console hex editor for unix systems. It has undo support (number of undo operations is only limited by available memory), ability to fill a range of addresses with the specified byte, ability to search for a single byte or character string. Offsets can be given in hexadecimal, octal or decimal. There are two editing modes: hex and ascii. In hex mode you type hexadecimal digits and in ascii mode you type characters. In the ascii mode cursor is automatically moved to the next byte after typing a character (this behaviour is configurable for hex mode). heme uses curses library for screen and input handling. Colors are supported and they may be configured in the configuration file (see below). If the configuration file isn't present, heme will use defaults. You may also specify which configuration file to use with the -c command line option.

-n, --no-backup-files
Don't make backup files.
-c, --config-file CONFIGFILE
Read configuration from CONFIGFILE. If not given, heme will try to read ~/.hemerc. If that fails, defaults will be used.
-d, --disable-colors
Don't use colors.
-h, --help
Show all available command line options.
-v, --version
Show heme version.

Keys (all are case-insensitive, except in the ascii mode):
left (right)
Move to previous (next) byte
up (down)
Move to previous (next) line
<
Move to beginning of line
>
Move to end of line
page up
Move 1 page up
page down
Move 1 page down
home
Move to beginning of file
end
Move to end of file
h
Display help screen
j
Jump to offset
n (w)
Search for byte (string)
r
Repeat last search
l
Fill range with byte
tab
Toggle between hex and ascii editing modes
u
Undo
s
Save file
q
Quit

Configuration file is expected to reside in ~/.hemerc. The syntax is very simple:

# this is a comment
option_1 = value
option_2 = "value 2"
Everything beyond the '#' is considered a comment and is ignored to the end of that line. Supported options are:
use_colors
Set this to 1 if you want colors, 0 otherwise (default: 1)
advance_after_edit
Set this to 1 if you want to advance to the next byte after editing byte at the current offset (default: 1)
make_backup_files
Set this to 1 if you want heme to make backup files, 0 otherwise (default: 1)
bg_color
Background color (default: "blue")
fg_color
Foreground color (default: "white")
bg_color_selected
Background color of selected byte (default: "black")
fg_color_selected
Foreground color of selected byte (default: "green")
bg_color_status
Background color of status lines (default: "cyan")
fg_color_status
Foreground color of status lines (default: "black")
Color names are "black", "red", "green", "yellow", "blue", "magenta", "cyan" and "white".

# This is sample configuration file.
 
advance_after_edit = 0
 
make_backup_files = 1
 
use_colors = 1
 
bg_color = black
 
fg_color = white
 
bg_color_selected = green
 
fg_color_selected = yellow
 
bg_color_status = blue
 
fg_color_status = white

~/.hemerc
