* CMDINPUT.C - handles command input (tab completion, history, etc.).
|
|
*
|
|
*
|
|
* History:
|
|
*
|
|
* 01/14/95 (Tim Norman)
|
|
* started.
|
|
*
|
|
* 08/08/95 (Matt Rains)
|
|
* i have cleaned up the source code. changes now bring this source
|
|
* into guidelines for recommended programming practice.
|
|
* i have added some constants to help making changes easier.
|
|
*
|
|
* 12/12/95 (Tim Norman)
|
|
* added findxy() function to get max x/y coordinates to display
|
|
* correctly on larger screens
|
|
*
|
|
* 12/14/95 (Tim Norman)
|
|
* fixed the Tab completion code that Matt Rains broke by moving local
|
|
* variables to a more global scope and forgetting to initialize them
|
|
* when needed
|
|
*
|
|
* 8/1/96 (Tim Norman)
|
|
* fixed a bug in tab completion that caused filenames at the beginning
|
|
* of the command-line to have their first letter truncated
|
|
*
|
|
* 9/1/96 (Tim Norman)
|
|
* fixed a silly bug using printf instead of fputs, where typing "%i"
|
|
* confused printf :)
|
|
*
|
|
* 6/14/97 (Steffan Kaiser)
|
|
* ctrl-break checking
|
|
*
|
|
* 6/7/97 (Marc Desrochers)
|
|
* recoded everything! now properly adjusts when text font is changed.
|
|
* removed findxy(), reposition(), and reprint(), as these functions
|
|
* were inefficient. added goxy() function as gotoxy() was buggy when
|
|
* the screen font was changed. the printf() problem with %i on the
|
|
* command line was fixed by doing printf("%s",str) instead of
|
|
* printf(str). Don't ask how I find em just be glad I do :)
|
|
*
|
|
* 7/12/97 (Tim Norman)
|
|
* Note: above changes preempted Steffan's ctrl-break checking.
|
|
*
|
|
* 7/7/97 (Marc Desrochers)
|
|
* rewrote a new findxy() because the new dir() used it. This
|
|
* findxy() simply returns the values of *maxx *maxy. In the
|
|
* future, please use the pointers, they will always be correct
|
|
* since they point to BIOS values.
|
|
*
|
|
* 7/8/97 (Marc Desrochers)
|
|
* once again removed findxy(), moved the *maxx, *maxy pointers
|
|
* global and included them as externs in command.h. Also added
|
|
* insert/overstrike capability
|
|
*
|
|
* 7/13/97 (Tim Norman)
|
|
* added different cursor appearance for insert/overstrike mode
|
|
*
|
|
* 7/13/97 (Tim Norman)
|
|
* changed my code to use _setcursortype until I can figure out why
|
|
* my code is crashing on some machines. It doesn't crash on mine :)
|
|
*
|
|
* 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* added config.h include
|
|
*
|
|
* 28-Jul-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* put ifdef's around filename completion code.
|
|
*
|
|
* 30-Jul-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* moved filename completion code to filecomp.c
|
|
* made second TAB display list of filename matches
|
|
*
|
|
* 31-Jul-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* Fixed bug where if you typed something, then hit HOME, then tried
|
|
* to type something else in insert mode, it crashed.
|
|
*
|
|
* 07-Aug-1998 (John P Price <linux-guru@gcfl.net>)
|
|
* Fixed carriage return output to better match MSDOS with echo
|
|
* on or off.(marked with "JPP 19980708")
|
|
*
|
|
* 13-Dec-1998 (Eric Kohl)
|
|
* Added insert/overwrite cursor.
|
|
*
|
|
* 25-Jan-1998 (Eric Kohl)
|
|
* Replaced CRT io functions by Win32 console io functions.
|
|
* This can handle <Shift>-<Tab> for 4NT filename completion.
|
|
* Unicode and redirection safe!
|
|
*
|
|
* 04-Feb-1999 (Eric Kohl)
|
|
* Fixed input bug. A "line feed" character remained in the keyboard
|
|
* input queue when you pressed <RETURN>. This sometimes caused
|
|
* some very strange effects.
|
|
* Fixed some command line editing annoyances.
|
|
*
|
|
* 30-Apr-2004 (Filip Navara <xnavara@volny.cz>)
|
|
* Fixed problems when the screen was scrolled away.
|
|
*
|
|
* 28-September-2007 (Hervé Poussineau)
|
|
* Added history possibilities to right key.
