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 | |
a0164df5 | 32 | ;; do M-x `describe-mode'. |
e41b2db1 | 33 | ;; |
a0164df5 | 34 | ;; NOTE: Remember to change `hexl-program' or `hexl-options' if needed. |
a2535589 JA |
35 | ;; |
36 | ;; Currently hexl only supports big endian hex output with 16 bit | |
37 | ;; grouping. | |
38 | ;; | |
39 | ;; -iso in `hexl-options' will allow iso characters to display in the | |
40 | ;; ASCII region of the screen (if your emacs supports this) instead of | |
41 | ;; changing them to dots. | |

101 | "\\<hexl-mode-map>A mode for editing binary files in hex dump format. |
102 | This is not an ordinary major mode; it alters some aspects | |
fe0a77c6 | 103 | of the current mode's behavior, but not all; also, you can exit |
330bd7c3 | 104 | Hexl mode and return to the previous mode using `hexl-mode-exit'. |
a2535589 JA |
105 | |
106 | This function automatically converts a buffer into the hexl format | |
107 | using the function `hexlify-buffer'. | |
108 | ||
8a1281b5 | 109 | Each line in the buffer has an \"address\" (displayed in hexadecimal) |
a2535589 JA |
110 | representing the offset into the file that the characters on this line |
111 | are at and 16 characters from the file (displayed as hexadecimal | |
112 | values grouped every 16 bits) and as their ASCII values. | |
113 | ||
114 | If any of the characters (displayed as ASCII characters) are | |
115 | unprintable (control or meta characters) they will be replaced as | |
116 | periods. | |
117 | ||
8a1281b5 RS |
118 | If `hexl-mode' is invoked with an argument the buffer is assumed to be |
119 | in hexl format. | |

139 | Movement is as simple as movement in a normal emacs text buffer. Most | |
140 | cursor movement bindings are the same (ie. Use \\[hexl-backward-char], \\[hexl-forward-char], \\[hexl-next-line], and \\[hexl-previous-line] | |
141 | to move the cursor left, right, down, and up). | |
142 | ||
143 | Advanced cursor movement commands (ala \\[hexl-beginning-of-line], \\[hexl-end-of-line], \\[hexl-beginning-of-buffer], and \\[hexl-end-of-buffer]) are | |
144 | also supported. | |
145 | ||
146 | There are several ways to change text in hexl mode: | |
147 | ||
148 | ASCII characters (character between space (0x20) and tilde (0x7E)) are | |
149 | bound to self-insert so you can simply type the character and it will | |
150 | insert itself (actually overstrike) into the buffer. | |
151 | ||
152 | \\[hexl-quoted-insert] followed by another keystroke allows you to insert the key even if | |
153 | it isn't bound to self-insert. An octal number can be supplied in place | |
154 | of another key to insert the octal number's ASCII representation. | |
155 | ||
156 | \\[hexl-insert-hex-char] will insert a given hexadecimal value (if it is between 0 and 0xFF) | |
157 | into the buffer at the current point. | |
158 | ||
159 | \\[hexl-insert-octal-char] will insert a given octal value (if it is between 0 and 0377) | |
160 | into the buffer at the current point. | |
161 | ||
162 | \\[hexl-insert-decimal-char] will insert a given decimal value (if it is between 0 and 255) | |
163 | into the buffer at the current point. | |
164 | ||
a2535589 JA |
165 | \\[hexl-mode-exit] will exit hexl-mode. |
166 | ||
31c75fa7 RS |
167 | Note: saving the file with any of the usual Emacs commands |
168 | will actually convert it back to binary format while saving. | |
a2535589 | 169 | |
330bd7c3 | 170 | You can use \\[hexl-find-file] to visit a file in Hexl mode. |
