Subject: v06i078: MicroEmacs, Version 3.7 (uEmacs3.7), Part08/12 Newsgroups: mod.sources Approved: rs@mirror.UUCP Submitted by: ihnp4!pur-ee!pur-phy!duncan!lawrence Mod.sources: Volume 6, Issue 78 Archive-name: uEmacs3.7/Part08 [ This is the latest revision of one of two programs named "MicroEmacs"; when discussing these on the net, or in contacting the authors, make sure to mention the version number -- in this case 3.7 -- as that is the easiest way to distinguish between them. Daniel will be posting uuencoded executables in net.micro.pc and net.micro.amiga; the file 'readme' contains information on how to also get these from him directly. --r$ ] echo extracting - main1.c sed 's/^X//' > main1.c << 'FRIDAY_NIGHT' X/* X * This program is in public domain; written by Dave G. Conroy. X * This file contains the main driving routine, and some keyboard processing X * code, for the MicroEMACS screen editor. X * X * REVISION HISTORY: X * X * 1.0 Steve Wilhite, 30-Nov-85 X * - Removed the old LK201 and VT100 logic. Added code to support the X * DEC Rainbow keyboard (which is a LK201 layout) using the the Level X * 1 Console In ROM INT.

X * 6-may-86 X * - re-orginized and wrote the update() function in display.c X * now my color hacks are in the right places and the code can be X * understood. X * [Released version 3.6f for BETA test sites] X * 8-may-86 X * - fixed bug in new display routine to wrap cursor on extended X * lines at the right time X * - modified the buffer-position command to give reasonable info X * 9-may-86 X * - improved the word wrap algorithm as not to discard non-space X * delimiters. The backscan now looks for white space rather than X * !inword(). X * [Released version 3.6g to Krannert] X * 10-may-86 X * - Added IBMPC.C an IBM-PC specific display driver. This makes paging X * 4-6 times faster. Also made some conditional changes to DISPLAY.C X * to eliminate the pscreen[] if using the PC driver. X * [changed version number to 3.6i] X * 12-may-86 X * - added delete-window (^X 0) command to dispose of a single window X * - fixed problem with multiple prefixes from a command line which X * was reported by John Gamble X * 14-may-86 X * - Added AZTEC support for the IBMPC display driver. Had to X * readjust some includes and defines for this. X * - fixed bug in delete-window. X * - fixed some bizarre behavior with the cursor after coming back X * from spawn calls. X * [changed version number to 3.7 Freezing development for net release] X * 15-may-86 X * - (that didn't last long...) Added execute-macro-(1 thru 20) commands X * to execute macro buffers (named "[Macro nn]") X * - changed BFTEMP to BFINVS and cleaned up treatment of invisable X * buffers. X * 16-may-86 X * - added store-macro (unbound) to store any executed command lines to X * macro buffer. X * - added clear-message-line (unbound) command to do just that X * - added resize-window command to change a window's size to the X * specified argument X * - improved help's logic not to re-read the file if it was already X * in a buffer X * - added MAGIC mode to all structures and command tables, but the X * regular expression code that John Gamble is writting is not ready. X * 18-may-86 X * - added interactive prompt requests in command line execution. IE X * while executing a macro, a parameter starting with an at sign (@) X * causes emacs to prompt with the rest of the parameter and return X * the resulting input as the value of the parameter. X * - added arguments to split-current-window to force the cursor into X * the upper or lower window. X * 20-may-86 X * - added support for the Microsoft C compiler as per the changes X * send in by Oliver Sharp X * - made some upgrades and fixes for VMS sent in by Guy Streeter X * 21-may-86 X * - fixed an AZTEC bug in ttgetc by clearing the upper byte X * - fixed buf in CMODE with #preprocesser input (bug fix submitted by X * Willis of unknown path) X * - added support of alternative startup file ( @<filename> ) in X * the command line X * - added ^Q quoting in interactive input (mlreplyt()). X * - added re-binding of meta-prefix and ctlx-prefix X * 22-may-86 X * - reorginize getkey routines to make more sense and let prefix X * binding work properly. X * 23-may-86 X * - checked new code on BSD4.2 made a few fixes X * - added optional fence matching while in CMODE X * - added goto and search command line arguments by Mike Spitzer X * 26-may-86 X * - added parameter fetching from buffers X * 27-may-86 X * - fixed some HP150 bugs...... X * 31-may-86 X * - Added Wang PC keyboard support from modifications by X * Sid Shapiro @ Wang Institute X * - Fixed some reverse video bugs with code submitted by Peter Chubb X * - Fixed bug in nextbuffer reported by Dave Forslund X * - added system V support (USG) from Linwood Varney X * 2-jun-86 X * - changed defines to just define one unix define (for example, X * just define BSD for Unix BSD 4.2) X * - Added Incremental search functions written by D. R. Banks X * in file ISEARCH.C X * - added insert-string (unbound) command to help the macro X * language out. X * - added unmark-buffer (M-~) command to turn off the current buffers X * change flag X * - fixed nxtarg to truncate strings longer than asked for max length X * 4-jun-86 X * - added special characters in command line tokens. Tidle (~) is X * the special leadin character for "nrtb". X * - Fixed bad ifdef in aztec code so it could look at HOME dir X * for startup, help, and emacs.rc files X * 6-jun-86 X * - make delete word commands clear the kill buffer if not after another X * kill command X * 11-jun-86 X * - made ~@ in string arguments pass as char(192) to nxtarg() so one can X * quote @ at the begining of string arguments X * - changed buffer size vars in listbuffers() to long (for big files) X * - re-wrote buffer-position command to be much faster X * 12-jun-86 X * - added count-words (M-^C) command to count the words/chars and X * lines in a region X * - changed regions so they could be larger than 65535 (short -> X * long in the REGION structure) X * - changed ldelete() and all callers to use a long size. The kill X * buffer will still have a problem >65535 that can not be solved X * until I restructure it. X * - grouped paragraph commands and word count together under symbol X * WORDPRO to allow them to be conditionally made (or not) X * 13-jun-86 X * - re-wrote kill buffer routines again. Now they support an unlimited X * size kill buffer, and are (in theory) faster. X * - changed delete-next-word (M-D) to not eat the newline after a word, X * instead it checks and eats a newline at the cursor. X * 17-jun-85 X * - added numeric argument to next/previous-window to access the nth X * window from the top/bottom X * - added support for the data General 10 MSDOS machine X * - added save-window (unbound) and restore-window (unbound) commands X * for the use of the menu script. Save-window remembers which window X * is current, and restore-window returns the cursor to that window. X * 20-jun-86 X * - fixed a bug with the fence matching locking up near the begining X * of a buffer X * - added argument to update to selectivaly force a complete update X * - added update-screen (unbound) command so macros can force a X * screen update X * 21-jun-86 X * - rearranged token() and nxtarg() calls so that command names and X * repeat counts could also be prompted and fetched from buffers X * - added write-message (unbound) command to write out a message X * on the message line (for macros) X * - changed ifdef's so that color modes are reconized as legal in X * b/w version, and simply do nothing (allowing us to use the same X * script files) X */ X X#include <stdio.h> X X/* make global definitions not external */ X#define maindef X X#include "estruct.h" /* global structures and defines */ X#include "efunc.h" /* function declarations and name table */ X#include "edef.h" /* global definitions */ X#include "ebind.h" /* default key bindings */ X X#if VMS X#include <ssdef.h> X#define GOOD (SS$_NORMAL) X#endif X X#ifndef GOOD X#define GOOD 0 X#endif X X#if APROF /* Declarations needed for AZTEC C profiling */ Xint _Corg(); /* first address of program */ Xint _Cend(); /* last address of program */ X Xshort monbuf[NBUCK]; /* buffer for gather info */ X#endif X Xmain(argc, argv) Xchar *argv[]; X{ X register int c; X register int f; X register int n; X register int mflag; X register BUFFER *bp; X register int ffile; /* first file flag */ X register int carg; /* current arg to scan */ X register int startf; /* startup executed flag */ X int basec; /* c stripped of meta character */ X int viewflag; /* are we starting in view mode?
