* Contains the declaration of the global version number variable.
*
* $Log: version.c,v $
*
* Revision 3.69grr 91/10/08 Greg Roelofs
* - Fixed several errors (typos) in os2.c.
* - Created new OS/2 makefile for use with MSC's NMAKE; fixed
* some errors (notably, lack of regexp and regsub).
* - Added a module definition file and made use of Kai Uwe Rommel's
* IsFileSystemFAT() code in os2.c to allow for HPFS long filenames.
* - ifdef'd out the vbeep code, since it doesn't seem to do anything
* under OS/2's ANSI driver (OS/2 1.30.1 XR05015).
*
* Revision 3.69b 90/04/24 David Kirschbaum
* Had to do minor tweaks to reduce/remove Turbo C v2.0 error and
* warning messages. Also enabled BIOS (instead of NANSI) screen
* I/O and HELP (for ":help" inline help .. nice!). [Executable
* uploaded to Simtel & wuarchive as {...}msdos/editor/stevi69x.zip]
*
* Revision 3.69a 90/02/04 dave
* A couple of minor bugfixes, and a whole load of enhancements:
* - Added tag-stacking.
* - Added searches for sentences and paragraphs.
* - Enhancements to "help" command:
* . Navigation of help screens, not just next-screen.
* . Index of help screens.
* . Screen for MSDOS-specific features.
* . Screen for :set commands.
* . A little context-sensitivity.
* - File mode is preserved (it wasn't in previous versions).
* - UNIX-like specifications of environments variables are expanded
* in file names. (E.g.- you can say :e $HOME/autoexec.bat)
* - PC keys for Insert & Delete now work.
* - Ported to Turbo C for the PC.
* - Integrated Larry Shurr's BIOS option for the PC.
* - Added color and multi-line options for the PC, and hooks for them
* in other systems.
* - Made "ctags" a little more general.
*
* Revision 3.69 89/08/13 11:41:58 tony
* Fixed a bug that caused messages from fileinfo() (in misccmds.c) to get
* screwed up. The routine smsg() which uses the kludge approach to varargs
* didn't have enough parameters for some of the calls made to it.
*
* Revision 3.68 89/08/06 09:51:20 tony
* Misc. minor changes to make lint happier before posting to USENET.
*
* Revision 3.67 89/08/03 13:08:52 tony
* There was some code in ops.c that was duplicating the function of the
* getcmdln() routine in cmdline.c. I modified getcmdln() to be slightly
* more general, and changed dofilter() in ops.c to use it.
*
* Revision 3.66 89/08/02 20:00:12 tony
* Fixed some problems with mode lines. There were still extra screen
* redraws that needed to be avoided. There was also a problem involving
* nested calls to docmdln() that can occur when mode lines are used.
*
* Revision 3.65 89/08/02 15:50:03 tony
* Finally got around to providing full support for the "change" operator.
* Multi-line changes (like "cL" or "3cc") now work correctly. Also fixed
* a small problem with multi-line character-oriented deletes leaving the
* cursor in the wrong location (off by one character). This is mainly
* useful for multi-line changes (such as "c%") so the insert starts in
* the right place.
*
* Revision 3.64 89/08/02 12:47:04 tony
* This message intentionally left blank.
*
* Revision 3.63 89/08/02 12:43:44 tony
* I just noticed that I had used the RCS cookie for log messages in one
* of my prior version messages. This caused these version update messages
* to be duplicated in this file. I just removed that string, and the
* extra message copies that had been generated.
*
* Revision 3.62 89/08/02 12:26:20 tony
* The ^G command now shows where you are in the file list, if more than one
* file is being edited. Also, the commands ":e#" and ":e!#" (note the lack
* of a space between the command and file name) will now work.
*
* Revision 3.61 89/08/02 11:03:16 tony
* Misc. cleanups regarding tags. Also added support for the "terse" option.
* This is ignored, but improves compatibility with vi, since we no longer
* complain about an unknown option if "terse" is used.
*
* Revision 3.60 89/08/02 09:26:39 tony
* Added code to avoid screen redraws when input is being read from the
* "stuffin" buffer. This avoids extra redraws when switching to the
* alternate file, or when invoking the editor with one of the "+" options,
* or when using tags.
*
* Revision 3.59 89/08/01 16:28:31 tony
* Added better support for counts on several cursor motion commands. These
* include ^F, ^B, f, F, t, T, as well as the repeated character search
* commands (command and semi-colon).
*
* Revision 3.58 89/07/19 08:08:23 tony
* Added the ability for '~' to be an operator. If enabled (by defined TILDEOP
* in env.h), the parameter "tildeop" (or "to") may be set to turn tilde into
* an operator.
*
* Revision 3.57 89/07/13 22:47:05 tony
* Made some generic speed improvements in screen.c and some TOS-specific
* improvements in tos.c. The TOS version is now much faster at screen
* updates than before.
*
* Revision 3.56 89/07/13 14:52:03 tony
* Minor cleanups in normal.c
*
* Revision 3.55 89/07/13 14:19:12 tony
* Cleaned up the logic in getcmdln() A LOT. The routine docmdln() needs a
* similar overhaul.
*
* Revision 3.54 89/07/12 21:40:01 tony
* Lots of misc. cleanup in normal.c and cmdline.c, but nothing much in the
* way of functional improvements. One change is that things like d/foo<CR>
* will now work since searches are less of a special case now.
*
* Revision 3.53 89/07/11 16:16:08 tony
* Added general support for interrupt-handling for those environments that
* can actually generate them. Basically, long-running operations are now
* able to terminate early if an error occurs. These operations are: string
* searches, the global command (":g/.../"), and file reads. File writes
* should probably be done as well, but this is more dangerous. In all cases,
* the user is given an indication on the status line that the operation
* terminated due to an interrupt.
*
* Revision 3.52 89/07/11 12:35:09 tony
* Improved the code in dosub() and doglob() that detects quoted characters
* and delimiters in search strings and replacement patterns. The current
* code didn't allow certain valid strings to be used. The delimiter is still
* required to be '/', but it can be quoted reliably now with backslash.
*
* Revision 3.51 89/07/10 14:01:58 tony
* Removed the function addtobuff() since it was rarely used and could be
* replaced by calls to other library functions. Also removed some other
* obsolete code that was already ifdef'd out anyway.
*
* Revision 3.50 89/07/10 13:10:32 tony
* Added a workaround in normal.c to avoid problems with broken versions of
* strncpy() that don't properly deal with a count of zero.
*
* Revision 3.49 89/07/07 16:28:37 tony
* Fixed a long-standing bug with 'cw' when the cursor is positioned on a
* word with only one character. Also fixed a problems with zero-length files
* and reverse searches.
*
* Revision 3.48 89/03/22 10:26:58 tony
* Fixed some outdated uses of the ":p" command (which has been changed to
* ":N" in os2.c and dos.c. Also added macros (F7 and F8) for dos and os/2
* to use the "cdecl" program to convert lines to and from a pseudo-english
* form. Use F7 to "explain" the declaration on the current line, and F8 to
* convert an english-style declaration to the C form. In both cases, the
* new form is placed on the next line, leaving the original line intact.
*
* Revision 3.47 89/03/11 22:44:14 tony
* General cleanup. Removed the static "rcsid" variables and the log
* strings (except in version.c). Fixed some coding style inconsistencies
* and added a few register declarations.
*
* Revision 3.46 89/02/14 09:52:07 tony
* Made a first pass at adding Robert Regn's changes, starting with the
* more portable ones. Added better support for '#' and '%' in colon
* commands, support for a configurable temp directory, and made the
* termcap code less picky about capabilities.
*
* Revision 3.45 88/11/10 09:00:06 tony
* Added support for mode lines. Strings like "vi:stuff:" or "ex:stuff:"
* occurring in the first or last 5 lines of a file cause the editor to
* pretend that "stuff" was types as a colon command. This examination
* is done only if the parameter "modelines" (or "ml") is set. This is
* not enabled, by default, because of the security implications involved.
*
* Revision 3.44 88/11/01 21:34:11 tony
* Fixed a couple of minor points for Minix, and improved the speed of
* the 'put' command dramatically.
*
* Revision 3.43 88/10/31 13:11:33 tony
* Added optional support for termcap. Initialization is done in term.c
* and also affects the system-dependent files. To enable termcap in those
* environments that support it, define the symbol "TERMCAP" in env.h
*
* Revision 3.42 88/10/27 18:30:19 tony
* Removed support for Megamax. Added '%' as an alias for '1,$'. Made the
* 'r' command more robust. Now prints the string on repeated searches.
* The ':=" command now works. Some pointer operations are now safer.
* The ":!" and ":sh" now work correctly. Re-organized the help screens
* a little.
*
* Revision 3.41 88/10/06 10:15:00 tony
* Fixed a bug involving ^Y that occurs when the cursor is on the last
* line, and the line above the screen is long. Also hacked up fileio.c
* to pass pathnames off to fixname() for system-dependent processing.
* Used under DOS & OS/2 to trim parts of the name appropriately.
*
* Revision 3.40 88/09/16 08:37:36 tony
* No longer beeps when repeated searches fail.
*
* Revision 3.39 88/09/06 06:51:07 tony
* Fixed a bug with shifts that was introduced when replace mode was added.
*
* Revision 3.38 88/08/31 20:48:28 tony
* Made another fix in search.c related to repeated searches.
*
* Revision 3.37 88/08/30 20:37:16 tony
* After much prodding from Mark, I finally added support for replace mode.
*
* Revision 3.36 88/08/26 13:46:34 tony
* Added support for the '!' (filter) operator.
*
* Revision 3.35 88/08/26 08:46:01 tony
* Misc. changes to make lint happy.
*
* Revision 3.34 88/08/25 15:13:36 tony
* Fixed a bug where the cursor didn't land on the right place after
* "beginning-of-word" searches if the word was preceded by the start
* of the line and a single character.
*
* Revision 3.33 88/08/23 12:53:08 tony
* Fixed a bug in ssearch() where repeated searches ('n' or 'N') resulted
* in dynamic memory being referenced after it was freed.
*
* Revision 3.32 88/08/17 07:37:07 tony
* Fixed a general problem in u_save() by checking both parameters for
* null values. The specific symptom was that a join on the last line of
* the file would crash the editor.
*
* Revision 3.31 88/07/09 20:39:38 tony
* Implemented the "line undo" command (i.e. 'U').
*
* Revision 3.30 88/06/28 07:54:22 tony
* Fixed a bug involving redo's of the '~' command. The redo would just
* repeat the replacement last performed instead of switching the case of
* the current character.
*
* Revision 3.29 88/06/26 14:53:19 tony
* Added support for a simple form of the "global" command. It supports
* commands of the form "g/pat/d" or "g/pat/p", to delete or print lines
* that match the given pattern. A range spec may be used to limit the
* lines to be searched.
*
* Revision 3.28 88/06/25 21:44:22 tony
* Fixed a problem in the processing of colon commands that caused
* substitutions of patterns containing white space to fail.
*
* Revision 3.27 88/06/20 14:52:21 tony
* Merged in changes for BSD Unix sent in by Michael Lichter.
*
* Revision 3.26 88/06/10 13:44:06 tony
* Fixed a bug involving writing out files with long pathnames. A small
* fixed size buffer was being used. The space for the backup file name
* is now allocated dynamically.
*
* Revision 3.25 88/05/04 08:29:02 tony
* Fixed a minor incompatibility with vi involving the 'G' command. Also
* changed the RCS version number of version.c to match the actual version
* of the editor.
*
* Revision 1.12 88/05/03 14:39:52 tony
* Changed the screen representation of the ascii character DELETE to be
* compatible with vi. Also merged in support for DOS.
*
* Revision 1.11 88/05/02 21:38:21 tony
* The code that reads files now handles boundary/error conditions much
* better, and generates status/error messages that are compatible with
* the real vi. Also fixed a bug in repeated reverse searches that got
* inserted in the recent changes to search.c.
*
* Revision 1.10 88/05/02 07:35:41 tony
* Fixed a bug in the routine plines() that was introduced during changes
* made for the last version.
*
* Revision 1.9 88/05/01 20:10:19 tony
* Fixed some problems with auto-indent, and added support for the "number"
* parameter.
*
* Revision 1.8 88/04/30 20:00:49 tony
* Added support for the auto-indent feature.
*
* Revision 1.7 88/04/29 14:50:11 tony
* Fixed a class of bugs involving commands like "ct)" where the cursor
* motion part of the operator can fail. If the motion failed, the operator
* was continued, with the cursor position unchanged. Cases like this were
* modified to abort the operation if the motion fails.
*
* Revision 1.6 88/04/28 08:19:35 tony
* Modified Henry Spencer's regular expression library to support new
* features that couldn't be done easily with the existing interface.
* This code is now a direct part of the editor source code. The editor
* now supports the "ignorecase" parameter, and multiple substitutions
* per line, as in "1,$s/foo/bar/g".
*
* Revision 1.5 88/04/24 21:38:00 tony
* Added preliminary support for the substitute command. Full range specs.
* are supported, but only a single substitution is allowed on each line.
*
* Revision 1.4 88/04/23 20:41:01 tony
* Worked around a problem with adding lines to the end of the buffer when
* the cursor is at the bottom of the screen (in misccmds.c). Also fixed a
* bug that caused reverse searches from the start of the file to bomb.
*
* Revision 1.3 88/03/24 08:57:00 tony
* Fixed a bug in cmdline() that had to do with backspacing out of colon
* commands or searches. Searches were okay, but colon commands backed out
* one backspace too early.
*
* Revision 1.2 88/03/21 16:47:55 tony
* Fixed a bug in renum() causing problems with large files (>6400 lines).
* Also moved system-specific defines out of stevie.h and into a new file
* named env.h. This keeps volatile information outside the scope of RCS.
*
* Revision 1.1 88/03/20 21:00:39 tony
* Initial revision
