By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19yy name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/Changes b/Changes new file mode 100644 index 0000000..b487596 --- /dev/null +++ b/Changes @@ -0,0 +1,172 @@ +september 2005: + - version 1.2.12 + - colored (fruit salad) display built by default (if use_default_colors available), + available through option --color (based on a patch from Yuri D'Elia) + +september 2005: + - version 1.2.11 + - add --enable-colors to build and have a colored (fruit salad) display + - allow entering goto "position" and "sector" in hexadecimal or not + - when prompting, propose previously entered value, and give ability to modify it + - fix setting mark after scrolling + - some cleanup + +may 2004: + - version 1.2.10 + - handle getnstr() not defined (needed for SGI IRIX 6.5.22) + +april 2004: + - version 1.2.9 (brown paper bag version) + - fix searching larger than 3 characters long strings + +january 2004: + - version 1.2.8 + - replace the unsafe getstr() with getnstr() (thanks to Richard Chadderton) + +august 2003: + - version 1.2.7 + - check the presence of before including it + - fix build on Digital UNIX 4.0f (remove -Wall) + - use the full width of the terminal (the trick is to stop relying on + printing "\n", but using move() instead) + - fix displaying the offsets at beginning of each line on big endian + boxes (thanks to Martin Schaffner) + +june 2003: + - version 1.2.6 + - fix core dump when searching backward (thanks to Jean Delvare) + (the culprit is memrmem, but also fixing provided memrchr) + +june 2003: + - version 1.2.5 + - fix build on Solaris (which doesn't have BLKGETSIZE and all compilers don't have -W) + +march 2003: + - version 1.2.4 + - use BLKGETSIZE to try to get the size of a device + - do not die horribly when accessing after the end + - fix provided memrchr() (thanks to Yue Luo) + - fix displaying after searching >32bit files (thanks to Paul Mattal) + +june 2002: + - version 1.2.3 + - add some KEY_HOME KEY_END (^[[7~ and ^[[8~) + - fix for HAVE_MEMMEM + - fix my memrchr not behaving the same as libc's + - fix the use of memrchr to behave as libc's + - use "(void)" in prototype of functions having no parameters + - call "raw()" when help() is over + +october 2001: + - version 1.2.2 + - yet again some s/int/INT/ (mainly in the "edited" list manipulation) + +june 2001: + - version 1.2.1 + - replace llseek with lseek + use of _FILE_OFFSET_BITS=64 + - memrchr&memmem now exists in some glibc's, so define it only if not provided + - cleanup basename declaration + - various cleanup in configure.in, now using autoheader + - a few bug fixes + +april 99: + - version 1.1.1 + - replaced lots of int by INT which 64bits + - replaced lseek by llseek (!! portability=linux :( !!) + +11 january 99: (:-<>, it's been a long time) + + - added many shortcuts so that F1..F12 and some others works on more + terms (xterm, rxvt, sgi's winterm...) + - removed the scanw that's badly handled on sgi (replaced by getstr + + sscanf) + +24 septembre 98: now displays the reached offset while searching + +10 september 98: hexedit 1.0.0 release + +08 september 98: Oliver Kiddle's changes: + - changed code where a function that returns a void was returning the + result of another function.

Funny things here (especially for froggies :) egrave = Alt+H , +ccedilla = Alt+G, Alt+Y = ugrave. +.br +.SS Modeline +At the bottom of the display you have the modeline (copied from emacs). As in +emacs, you have the indications --, ** and %% meaning unmodified, modified and +read-only. Then you have the name of the file you're currently editing. Next to +it is the current position of the cursor in the file followed by the total file +size. The total file size isn't quite correct for devices. +.br +While in --sector mode, it shows the sector the cursor is in. +.SS Editing +You can edit in ASCII or in hexadecimal. You can switch between the two with +\fITab\fR. When the file is read-only, you can't edit it. When trying to edit a +read-only file, a message (``File is read-only'') tells you it is non-writable. +.br +The modifications are shown in bold until they are saved. +The modeline indicates whether you have modified the file or not. +.br +When editing in hexadecimal, only \fI0\fR,\fI1\fR,...,\fI9\fR, +\fIa\fR,\fIb\fR,...,\fIf\fR, \fIA\fR,\fIB\fR,...\fIF\fR are legal. +Other keys are unbound. The first time you hit an unbound key, the help pops up. +It won't pop again unless you call the help directly (with \fIF1\fR). +.br +When editing in ascii, you can find it difficult to enter characters like +\fI/\fR which are bound to a function. The solution is to use the quoted insert +function \fICtrl+Q\fR, the key after the quoted insert function is not processed +by \fIhexedit\fR (like emacs' quoted-insert, or like the \\ character in C). +.SS Searching +You can search for a string in ASCII or in hexadecimal. You can switch +between the two with \fITab\fR. If the string is found, the cursor is moved to +the beginning of the matching location. If the search failed, a message (``not +found'') tells you so. You can cancel the search by pressing a key. +.br +The search in hexadecimal is a bit confusing. You must give a hexadecimal string +with an even number of characters. The search can then be done byte by byte. If +you want to search a long number (eg: a 32 bit number), you must know the +internal representation of that number (little/big endian problem) and give it +the way it is in memory. For example, on an Intel processor (little endian), you +must swap every bytes: 0x12345678 is written 0x78563412 in memory and that's the +string you must give to the search engine. +.br +Before searching you are asked if you want to save the changes, if the file is +edited. +.SS Selecting, copying, pasting, filling +First, select the part of the buffer you want to copy: start setting the mark +where you want. Then go to the end of the area you want to copy (you can use the +go to function and the search functions). Then copy it. You can then paste the +copied area in the current file or in another file. +.PP +You can also fill the selected area with a string or a character: start choosing +the block you want to fill in (set mark then move to the end of the block), and +call the fill function (\fIF12\fR). \fIhexedit\fR ask you the string you want to +fill the block with. +.br +The code is not tuned for huge filling as it keeps the modifications in memory +until you save them. That's why \fIhexedit\fR will warn you if you try to fill +in a big block. +.PP +When the mark is set, the selection is shown in reverse mode. +.br +Be aware that the copied area contains the modifications done at the time of the +copy. But if you undo the modifications, it does not change the content of the +copy buffer. It seems obvious but it's worth saying. +.SS Scrolling +The scrolling is different whether you are in \fI\-\-sector\fR mode or not. In +normal mode, the scrolling is line by line. In sector mode, the scrolling is +sector by sector. In both modes, you can force the display to start at a given +position using \fIEsc+L\fR. +.SH SEE ALSO +od(1), hdump(1), hexdump(1), bpe(1), hexed(1), beav(1). +.SH AUTHOR +Pixel (Pascal Rigaux) , +.br +Home page is . +.SH UNRESTRICTIONS +.I hexedit +is Open Source; anyone may redistribute copies of +.I hexedit +to +anyone under the terms stated in the GNU General Public License. +.PP +You can find +.I hexedit +at +.br + and +.br +. +.SH TODO +Anything you think could be nice... +.SH LIMITATIONS +There are problems with the curses library given with Redhat 5.0 that make +\fIhexedit\fR think the terminal is huge. The result is that hexedit is +not usable. +.PP +The shortcuts work on some machines, and not on others. That's why there are +many shortcuts for each function. The Ctrl+Arrows and the Alt+. do not work +work as they should most of the time. On SUNs, you must do Ctrl+V-Ctrl+V instead +of Ctrl+V (!); and the Alt key is the diamond one. +.PP +While searching, it could be interesting to know which position the search has +reached. It's always nice to see something moving to help waiting. +.PP +The hexadecimal search could be able to search modulo 4 bits instead of 8 bits. +Another feature could be to complete padd odd length hexadecimal searches with +zeros. +.SH BUGS +I have an example where the display is completly screwed up. It seems to be a +bug in ncurses (or maybe in xterm and rxvt)?? Don't know if it's me using +ncurses badly or not...
