| 7 | 1 /* xxd: my hexdump facility. jw |
| 2 * | |
| 3 * 2.10.90 changed to word output | |
| 4 * 3.03.93 new indent style, dumb bug inserted and fixed. | |
| 5 * -c option, mls | |
| 6 * 26.04.94 better option parser, -ps, -l, -s added. | |
| 7 * 1.07.94 -r badly needs - as input file. Per default autoskip over | |
| 1197 | 8 * consecutive lines of zeroes, as unix od does. |
| 7 | 9 * -a shows them too. |
| 10 * -i dump as c-style #include "file.h" | |
| 11 * 1.11.95 if "xxd -i" knows the filename, an 'unsigned char filename_bits[]' | |
| 12 * array is written in correct c-syntax. | |
| 13 * -s improved, now defaults to absolute seek, relative requires a '+'. | |
| 14 * -r improved, now -r -s -0x... is supported. | |
| 15 * change/suppress leading '\0' bytes. | |
| 16 * -l n improved: stops exactly after n bytes. | |
| 17 * -r improved, better handling of partial lines with trailing garbage. | |
| 18 * -r improved, now -r -p works again! | |
| 19 * -r improved, less flushing, much faster now! (that was silly) | |
| 20 * 3.04.96 Per repeated request of a single person: autoskip defaults to off. | |
| 21 * 15.05.96 -v added. They want to know the version. | |
| 22 * -a fixed, to show last line inf file ends in all zeros. | |
| 23 * -u added: Print upper case hex-letters, as preferred by unix bc. | |
| 24 * -h added to usage message. Usage message extended. | |
| 25 * Now using outfile if specified even in normal mode, aehem. | |
| 26 * No longer mixing of ints and longs. May help doze people. | |
| 27 * Added binify ioctl for same reason. (Enough Doze stress for 1996!) | |
| 28 * 16.05.96 -p improved, removed occasional superfluous linefeed. | |
| 29 * 20.05.96 -l 0 fixed. tried to read anyway. | |
| 30 * 21.05.96 -i fixed. now honours -u, and prepends __ to numeric filenames. | |
| 31 * compile -DWIN32 for NT or W95. George V. Reilly, * -v improved :-) | |
| 32 * support --gnuish-longhorn-options | |
| 33 * 25.05.96 MAC support added: CodeWarrior already uses ``outline'' in Types.h | |
| 34 * which is included by MacHeaders (Axel Kielhorn). Renamed to | |
| 35 * xxdline(). | |
| 36 * 7.06.96 -i printed 'int' instead of 'char'. *blush* | |
| 37 * added Bram's OS2 ifdefs... | |

|
38 * 18.07.96 gcc -Wall @ SunOS4 is now silent. |
| 7 | 39 * Added osver for MSDOS/DJGPP/WIN32. |
| 40 * 29.08.96 Added size_t to strncmp() for Amiga. | |
| 41 * 24.03.97 Windows NT support (Phil Hanna). Clean exit for Amiga WB (Bram) | |
| 42 * 02.04.97 Added -E option, to have EBCDIC translation instead of ASCII | |
| 216 | 43 * (azc10@yahoo.com) |
| 7 | 44 * 22.05.97 added -g (group octets) option (jcook@namerica.kla.com). |
| 45 * 23.09.98 nasty -p -r misfeature fixed: slightly wrong output, when -c was | |
| 46 * missing or wrong. | |
| 47 * 26.09.98 Fixed: 'xxd -i infile outfile' did not truncate outfile. | |
| 48 * 27.10.98 Fixed: -g option parser required blank. | |
| 49 * option -b added: 01000101 binary output in normal format. | |
| 50 * 16.05.00 Added VAXC changes by Stephen P. Wall | |
| 1197 | 51 * 16.05.00 Improved MMS file and merge for VMS by Zoltan Arpadffy |
