The editor has two display areas, one for displaying the -entry currently being manipulated, and one for displaying the complete -DRCS. Commands to the editor take the form of function keys. -.PP -.I Fontedit -takes one command line parameter, a file name. This file is -used to save the character set. If the file exists when \fIfontedit\fP -is invoked, it is read in to initialize the DRCS. The file is written -to when \fIfontedit\fP exits. -.PP -Commands to fontedit take the form of function keys. The current -definitions are: -.IP \fBHELP\fP -Display a help screen. -.IP \fBF6\fP -Turn the pixel under the cursor on. -.IP \fBF7\fP -Turn the pixel under the cursor off. -.IP \fBF13\fP -Clear the display area. -.IP \fBFind\fP -Save the current font in the font table. Update the DRCS display. -.IP \fBSelect\fP -Extract the entry selected by the cursor in the DRCS display. -.IP \fBPrev\fP -Move the cursor to the previous entry in the DRCS display. -.IP \fBNext\fP -Move the cursor to the next entry in the DRCS display. -.IP \fBInsert\fP -Insert a blank line at the current cursor position. The bottom row is lost. -.IP \fBRemove\fP -Remove the row at the current cursor position. All rows below the -current one are shifted up. -.IP \fBCursors\fP -Move the cursor in the main display area. -.PP -If the screen gets garbled, press <control-L>. -.PP -To exit \fIfontedit\fP, press <control-D>. The DRCS will be saved in -\fIfile\fP. To exit without saving the DRCS, hit interrupt (usually -DEL). -.SH DIAGNOSTICS -.I Fontedit -will issue a warning when the entry being worked on is not saved, and -some potentially destructive command, like \fBSelect\fP is used. To -override the warning message, immediately reissue the command. -.SH AUTHOR -Greg Franks. - - diff --git a/usr.sbin/pcvt/fontedit/fontedit.c b/usr.sbin/pcvt/fontedit/fontedit.c deleted file mode 100644 index d9ed357c..0000000 --- a/usr.sbin/pcvt/fontedit/fontedit.c +++ /dev/null @@ -1,925 +0,0 @@ -/* - * fontedit - * Fonteditor for VT220 - * - * BUGS: - * o Cursor motion is less than optimal (but who cares at 9600), - * - * COMPILE: - * cc -O fontedit.c -o fontedit - * (use Makefile) - * - * Copyright (c) 1987 by Greg Franks. - * - * Permission is granted to do anything you want with this program - * except claim that you wrote it. - * - * - * REVISION HISTORY: - * - * Nov 21, 1987 - Fixed man page to say "Fontedit" instead of "Top" - * Nov 22, 1987 - Added BSD Compatible ioctl, turned cursor on/off - * - eap@bucsf.bu.edu - */ - -void clear_screen();
