JOVE is * X * provided to you without charge, and with no warranty. You may give * X * away copies of JOVE, including sources, provided that this notice is * X * included in all the files. * X ************************************************************************/ X XTo make JOVE edit Makefile to set the right directories for the binaries, Xonline documentation, the man pages, and the TMP files. (IMPORTANT! read Xthe Makefile carefully.) "tune.c" will be created from "tune.template" by XMAKE automatically, and it will use the directories you specified in the XMakefile. (NOTE: You should never edit tune.c directly because your Xchanges will be undone by the next make. If you want to make a change to a Xpart of tune.c that isn't a directory name, you should edit tune.template.) XNext you must edit "tune.h" selecting the compile time options you care Xabout. See below for a description of all the compile time options. You Xcan type "make" to compile XJOVE, PORTSRV (this is compiled but not used on X4.2+ systems), JOVE_RECOVER and TEACHJOVE. Test them out to see if they Xwork. If they do, type "make install" to install everything where it Xbelongs. X XHere are some things to consider for deciding where to put the tmp files. XTMPDIR is where the tmp files get stored, usually /tmp or /tmp/jove. If Xyour system does not remove subdirectories of /tmp on reboot (lots do Xremove them these days) then it makes sense to make TMPDIR be /tmp/jove. XBut if you want to recover buffers on system crashes, you should create a Xdirectory that doesn't get clearned upon reboot, and use that instead. XYou would probably want to clean out that directory periodically with X/etc/cron. X XFor the pdp11 version there is the Ovmakefile. This has only been tested Xon 2.9bsd. It works pretty well, actually, and it is possible to turn on Xall the compile time options with this version. X XBug reports: If you find bugs in JOVE I would appreciate hearing about Xthem. (My net address is at end of this message.) So, send me the bug Xreports. If the bug isn't already fixed, I will ask you to send me the Xfix. If you haven't found the bug, I may be able to, so don't wait until Xyou have found it. If you make improvements to JOVE and want them Xincorporated into the official version, send me a message explaining what Xthe change is, and I will decide whether I want to include it. If it is Xpossible for your change to be #ifdef'd in, that would be best, since I Xwant to avoid making JOVE huge. For instance, if it's a new package type Xthing (say, like word abbrev. mode, or something) then it would be best Xif that were a compile-time option. I will send out periodic updates to Xmod.sources. I will report all significant bug fixes there, and to Xnet.emacs as well. X XHere's a list of the compile time options and what they mean: X XABBREV - Enables word-abbrev-mode which again is nice for paper writers. X XBACKUPFILES - This enables backing up files on write. I guess lots of X people like this feature. It enables the feature but you X can still control whether files are backed up with the X make-backup-files variable. X XBIFF - This enables turning on and off BIFF so your screen doesn't X get messed up with messages from BIFF. X XBSD4_2 - Obviously, if you're a Berkeley 4.2 system. X XBSD4_3 - If you're running a Berkeley 4.3 (or very late 4.2) system. X This will automatically define BSD4_2, also. X XCHDIR - This enables the directory commands; PUSHD, POPD, DIRS and X CD. These simulate the csh commands I think exactly. As X a side-effect, absolute pathnames are enabled, which means X JOVE parses filenames for "." and ".." and all that to get X at what you REALLY mean. It's nicer when this is enabled, X but not essential. X XCMT_FMT - This enables code to format and indent C comments. X XID_CHAR - Enables support for Insert/Delete character on terminals X that have those capabilites. Couple of problems with this code: X it's large, takes up lots of I space which is a problem for the X smaller computers (pdp11). Also, it isn't particularly smart X and sometimes does really stupid things. It sometimes uses X insert/delete character when simply redrawing would have been X faster. And if you look at code you'll understand why I don't X like it all that much. X XIPROCS - Nice feature which lets you run interactive UNIX commands in X windows. In particular, there is a an i-shell command built X in which starts up an interactive shell in a window. This works X only on systems with JOB_CONTROL since it relies on the fancy X signal mechanism. X XJOB_CONTROL - Versions of UNIX that have the job control facility. X Berkeley 2.9 system, and the 4.1-3 systems I know have X job stopping, so if you're one of those, define X this. The reason MENLO_JCL is defined when JOB_CONTROL X is that the 2.9 signal.h file only defines all of the job X stopping signals only when MENLO_JCL is defined. X XLISP - Enables Lisp Mode. This includes code to indent "properly" X for Lisp code and new routines to move over s-expressions. X You probably won't want (or need) this on PDP-11's. X XLSRHS - This is for the Lincoln-Sudbury Regional High School version X of jove, which is where JOVE originated. X XMY_MALLOC - Use the older version of malloc that is more memory efficient X for the VAX. This is MUCH more efficient than the VAX one. X The VAX version seems to place more importance on the speed X of the allocation than the amount of memory it uses. Make your X choice ... JOVE hardly ever calls malloc, anyway, relatively X speaking, since it allocates lines in big chunks. NOTE: This X seems not to work on suns. X XPIPEPROCS - If NOT defined, JOVE will use the Berkeley pseudo-ttys when X doing interactive processes. This is infinitely better, X since you get job control and all that stuff on i-shells. X If defined, the portsrv program will have to be made, and X everything will be done using pipes. X XRESHAPING - This is for BRL or Berkeley 4.3 systems. It's not something I X dealt with so I can't really describe it. Got something to do X with reshaping the windows that UNIX knows about. When you try X to reshape one of those windows, it sends some signal which JOVE X catches and uses to resize its windows. X XSPELL - Enables the spell-buffer and parse-spelling-errors commands. X They are nice especially if you have lots of paper writers. X XWIRED_TERMS - Include compiled-in hard-wired code for certain terminals, X like the Concept 100. If you don't have these terminals, X you probably don't need this (but no point in taking it X out unless you're low on space). X XTo make macro files compatible between machines with different byte order I Xuse the ntohl() and htonl() calls that are supplied with (as far as I know) X4.2 systems. If you're not running 4.2 a bunch of macros will be defined Xautomatically in macros.c. From Dave Curry: X The "#if" gets all the identifiers of backwards (left-endian) X machines, the "#else" handles normal (right-endian) X machines.... Just add some remark in the READ_ME for people X porting to machines other than the Vax or PDP-11 which are X left-endian. X X"doc/system.rc" and "doc/example.rc" are jove initialization files. X"system.rc" is the "system" rc file here at UoR, and it gets ready every Xtime JOVE starts up FOR EVERYONE. ("make install" should copy the Xsystem-wide .joverc to the right place automatically.) After that JOVE Xreads an initialization file in the user's home directory, and "example.rc" Xis mine. X XThe files "jove.[12345]" in DOC are the official JOVE manual. I got Xpermission from Richard Stallman to use his manual for the original EMACS, Xmodifying it where necessary for JOVE. Lots of work was done by Brian XHarvey on this manual. X XThere are man pages for jove, recover and teachjove. Teachjove is for Xpeople who have never used EMACS style editors. It is an interactive Xtutorial, THE tutorial written by Stallman for the original EMACS, only Xslightly modified for JOVE in the appropriate places. The man pages are Xcompletely up to date, thanks to me. X XThanks to Jay Fenlason at Berkeley for writing the original pty code. X XThanks to Dave Curry at Purdue for putting in tons of time and effort Xinto getting JOVE ready. It just wouldn't be working without his help. X XThanks to Jeff Mc Carrell at Berkeley for finding bugs and adding features. X X(Thanks to Brian Harvey for teaching me about linked lists ...) X XGood luck, have fun.
