UUD/UUE (was Re: uuencode.c request)

Archive-name: uux/part01
I have been enjoying the manual uudecoding of these files ;-(
So herewith I post a better version. UUE can automatically encode and
split a file into n parts. It also provides for better error-checking
and it includes an ASCII table in case the message might traverse
certain BITNET sites. UUD can automatically decode multipart files
created by UUE.
UUD/UUE compile on Unix, VAX, MSDOS, and GEMDOS. Updates and comments
are appreciated.

X================================================================================

XThis is the v3.3 19-Apr-88 version of uud.ttp (and v3.1 of uue.ttp too)
XIt is named uud instead of uudecode, to avoid confusion between different
Ximplementations of the uudecoding functionnality.
XIdem for uue.
X
XThese versions have the following capabilities:
X1- Missing trailing blanks are still OK. (I am on EARN/BITNET ...)
X Absolutely no need for any procedure to restore 61 chars a line...
X2- **Some** common internetwork transpositions are OK (e.g.
X tilde instead of circonflex...but not coma instead of circonflex!)
X (I am still on EARN/BITNET)
X No need to edit the file to change chars...
X Note: I have been told that the substitution of blanks by grave
X accent is not a gateway/network bug, but a feature of some recent
X UN*X uuencode, to avoid the blank compression by some protocols.
X Note: It is *NOT* BITNET/EARN that damage the files, we transfert non
X encoded binaries on this network, but put the blame on some brain damaged
X gateways. (One of them, between Usenet and Bitnet, is really ruining
X files... Totally wrong ASCII -> EBCDIC table)
X3- Multi-file decoding is OK, by the 'include xxx' and 'begin part n' lines.
X To allow for identififation of the original file in the parts, the file
X name is now provided in the 'begin part n' line.
X4- If the included files do not exist, uud.ttp will attempt to go on with the
X same file, in case the multiple files have just been concatenated upon
X reception.
X5- There is a line sequence checking possible, allowing the detection of
X missing, duplicate, corrupted lines or files. (I have sloppy fingers when
X editing ...)
X This feature is enabled if the first line of the 1st uuencoded file
X is postfixed with a 'z', this is done automatically by the uue.ttp
X companion program.
X Note: a bug of the previous version is fixed.
X6- A complete check of the uudecoding process is possible, by use of the
X -d flag. This will tell you about all whats going on in there, plus
X this is enabling a complete character by character check of the file
X while decoding. This should make some subtle file corruptions pop up,
X as all the uudecode do not check whats in a line before doing their job.
X If this option detect an error, then the file produced will not be
X correct (uud stops at the first error detected, and close the file).
X7- If there is a character table present before each file, it will be used,
X this table is produced by the companion uue.
X The use of this table allows for some incredible recovery of files that
X went through some really brain damage gateway. No sweat.
X8- You can decode a single file contaning several uuencoded files, at once;
X You give a complete month of INFO-ATARI16 digest, and voila all the
X nice PD .prg's, no editing, no sweat. (To be true, it's been a long time
X without *.prg in the digests..., but you should try it.)
X9- The files are completely compatible with true UN*X uudecode/uuencode.
X As long as you do not use the multiple part option of uue.ttp.
X10- Compile on the ST, using MWC, on UN*X System V and on TOPS20 using cc.
X
X
XEn resume: get the mail file containing what you want to decode, on the
XAtari ST, and apply uud.ttp on it, without any editing of any sort, including
Xremoving mail header. (except for multiple parts, where the file names must be
Xcorrect, but no need to edit individual files).
X
X
Xuud v3.3 is the result of:
X1. fixing a bug (nobody, but me, complained about it)
X2. Having a source that compile and run successfully on
X Atari ST, MS-DOS and UNIX. (Nobody got an Amiga around here)
X I did the coding/compiling/testing for all 3 systems;
X For UNIX, it is done using cc on a real/certified SystemVr2
X For Atari, it is done using MWC 2.x.
X For the PC, it is done with MSC 4.0. (An attempt with
X Turbo C did not give me any thing that run correctly)
X (I discovered a slight bug in MSC 4.0 too, but no big deal.)
X3. Adding some requested features:
X A. The -t option to allow for a full disk/directory target
X specification, on which the uuencoded filename is appended.
X The resulting pathname is where the result of the decoding
X will be written.
X B. The -s option: idem -t, but for the source file.
X C. the -n option to disable the line sequence checking, in case
X of uue'ed files, for any good/bad reason.
X
X
X The maximum command line can thus be like:
X uud -d -n -t c:^binaries^ -s d:^encoded^ file.uue
X -d : enable the verbose/debugging option, telling you what
X uud is doing, and sometimes even why...
X -n : suppress the line sequence checking. (Totally useless option)
X (The line checking is turned off automagically for files
X that where not uuencoded by uue, even now for the files with
X lines terminated by the 'z' char... no more fuzz about them...)
X -t directory : where the output file(s) will be written, in this case
X must be terminated by the directory separator character;
X -s directory : where uud is going to find the file(s) to
X decode.
X4. This uud can decode line with 80 uuencoded char, instead of the
X usual 60, the next generation of uue will take advantage of that.
X5. If the file name on the command line,
X is replaced by the character '-' then
X standard input will be read, instead of a named file.
X (For the heavy UNIX news reader...)
X6. typing uud alone on a line, or invoking it without arguments
X from the desktop, will give you the usage with a reminder
X about the options.
X
XBig news for Atari/PC users with only restricted disks,
Xyou can decode now much larger files, as the uud.ttp, source
Xand destination files can all be on separate disks.
X
XIf given no args, uud will tells you what version is this, and the usage.
XWith the -d option, a whole lot of checking is done, and it is telling
Xyou all that it is doing.
XIn all case if there is anything else that a perfect decoding, you will
Xhave some message and you'll need to press any key to exit. (I anybody
Xtell me how to tell if we are working from the desktop, or from a shell,
XI will make the pause valid only if run from the desktop. Some kind soul
Xwith an exemple ? I suppose I have to look into the base page...)
XIn case of any error, the produced file is not valid.
