28 ;; This package implements a major mode for editing binary files. It uses
29 ;; a program called hexl, supplied with the GNU Emacs distribution, that
30 ;; can filter a binary into an editable format or from the format back into
31 ;; binary. For full instructions, invoke `hexl-mode' on an empty buffer and
32 ;; do `M-x describe-mode'.
34 ;; This may be useful in your .emacs:
36 ;; (autoload 'hexl-find-file "hexl"
37 ;; "Edit file FILENAME in hexl-mode." t)
39 ;; (define-key global-map "\C-c\C-h" 'hexl-find-file)
41 ;; NOTE: Remember to change HEXL-PROGRAM or HEXL-OPTIONS if needed.
43 ;; Currently hexl only supports big endian hex output with 16 bit
46 ;; -iso in `hexl-options' will allow iso characters to display in the
47 ;; ASCII region of the screen (if your emacs supports this) instead of
48 ;; changing them to dots.

93 A major mode for editing binary files in hex dump format.
95 This function automatically converts a buffer into the hexl format
96 using the function `hexlify-buffer'.
98 Each line in the buffer has an \"address\" (displayed in hexadecimal)
99 representing the offset into the file that the characters on this line
100 are at and 16 characters from the file (displayed as hexadecimal
101 values grouped every 16 bits) and as their ASCII values.
103 If any of the characters (displayed as ASCII characters) are
104 unprintable (control or meta characters) they will be replaced as
107 If `hexl-mode' is invoked with an argument the buffer is assumed to be

128 Movement is as simple as movement in a normal emacs text buffer. Most
129 cursor movement bindings are the same (ie. Use \\[hexl-backward-char], \\[hexl-forward-char], \\[hexl-next-line], and \\[hexl-previous-line]
130 to move the cursor left, right, down, and up).
132 Advanced cursor movement commands (ala \\[hexl-beginning-of-line], \\[hexl-end-of-line], \\[hexl-beginning-of-buffer], and \\[hexl-end-of-buffer]) are
135 There are several ways to change text in hexl mode:
137 ASCII characters (character between space (0x20) and tilde (0x7E)) are
138 bound to self-insert so you can simply type the character and it will
139 insert itself (actually overstrike) into the buffer.
141 \\[hexl-quoted-insert] followed by another keystroke allows you to insert the key even if
142 it isn't bound to self-insert. An octal number can be supplied in place
143 of another key to insert the octal number's ASCII representation.
145 \\[hexl-insert-hex-char] will insert a given hexadecimal value (if it is between 0 and 0xFF)
146 into the buffer at the current point.
148 \\[hexl-insert-octal-char] will insert a given octal value (if it is between 0 and 0377)
149 into the buffer at the current point.
151 \\[hexl-insert-decimal-char] will insert a given decimal value (if it is between 0 and 255)
152 into the buffer at the current point.
154 \\[hexl-mode-exit] will exit hexl-mode.
156 Note: saving the file with any of the usual Emacs commands
157 will actually convert it back to binary format while saving.
159 You can use \\[hexl-find-file] to visit a file in hexl-mode.
161 \\[describe-bindings] for advanced commands."
