PLASMA comes with a text editor targeting code development. The command line options are:
+ED [FILENAME [LINE #]]
The filename can be a new file or an existing file. If it's an existing file, it will be loaded into the editor. Additionally, a line number can be entered and the cursor will jump right to the line. This is useful when compiling a PLASMA module and an error is returned, indicated by a line number.
From the EDITOR.README file:
WELCOME TO THE PLASMA EDITOR!
FIRST THINGS FIRST: TO NAVIGATE, USE THE ARROW KEYS. ON THE APPLE ][:
CTRL-K = UP
CTRL-J = DOWN.
TO JUMP AROUND THE TEXT FILE USE:
CTRL-W = JUMP UP
CTRL-Z = JUMP DOWN
CTRL-A = JUMP LEFT
CTRL-S = JUMP RIGHT
CTRL-Q = JUMP BEGINNING
CTRL-E = JUMP END
THE 'ESCAPE' KEY WILL PUT YOU IN COMMAND MODE. FROM THERE YOU CAN EXIT BY ENTERING 'Q' AND 'RETURN'. YOU CAN ALSO RETURN TO THE EDITOR BY JUST PRESSING 'RETURN'.
THE PLASMA EDITOR IS A SIMPLE TEXT EDITOR FOR ENTERING AND MANIPULATING TEXT AND SOURCE CODE FILES. THE EDITOR ONLY SUPPORTS 40 COLUMN TEXT ALTHOUGH LINES CAN BE UP TO 79 CHARACTERS LONG. THE SCREEN WILL SCROLL HORIZONTALLY AS THE CURSOR MOVES. THERE IS 16K OF MEMORY FOR THE TEXT BUFFER.
IT HAS TWO MODES, COMMAND AND EDIT.
EDIT COMMANDS:
LEFT ARROW = MOVE CHAR LEFT
RIGHT ARROW = MOVE CHAR RIGHT
UP ARROW = MOVE LINE UP
DOWN ARROW = MOVE LINE DOWN
CTRL-K = MOVE LINE UP
CTRL-J = MOVE LINE DOWN
CTRL-A = JUMP LEFT
CTRL-S = JUMP RIGHT
CTRL-W = JUMP UP
CTRL-Z = JUMP DOWN
CTRL-Q = JUMP BEGIN
CTRL-E = JUMP END
CTRL-D = DELETE CHAR
CTRL-B = BEGIN SELECTION
CTRL-C = COPY SELECTION INTO CLIPBOARD
CTRL-X = CUT SELECTION INTO CLIPBOARD
CTRL-V = PASTE CLIPBOARD
CTRL-O = OPEN NEW LINE
CTRL-F = OPEN A FOLLOWING NEW LINE
CTRL-T = JOIN LINES
CTRL-Y = TOGGLE INSERT/OVERWRITE
TAB/CTRL-I = INSERT SPACES TO NEXT TAB
= INDENT SELECTION IF INSERT MODE
= UNDENT SELECTION IF OVERWITE MODE
ESCAPE = SWITCH TO COMMAND MODE
DELETE = DELETE CHAR LEFT
APPLE ][ FEATURES:
SHIFT-M = ]
CTRL-N = [
SHIFT-CTRL-N = ~
CTRL-P = \
SHIFT-CTRL-P = |
CTRL-G = _
CTRL-L = SHIFT LOCK
SHIFT-LEFT ARROW = DELETE (SHIFT-MOD)
WITH THE SHIFT-KEY MOD ON AN APPLE ][, UPPER AND LOWER CASE ENTRY WORKS AS EXPECTED.
ESC T C = FORCE LOWER-CASE CHARS
If you have a lower-case character generator installed, you can force lower-case display. Otherwise, upper case will be displayed normally but lower-case will be displayed in inverse. This is the default.
Apple //e AND //c FEATURES:
The 'SOLID-APPLE' key will modify theese keys:
SA-RETURN = OPEN FOLLOWING LINE
SA-LEFT ARROW = JUMP LEFT
SA-RIGHT ARROW = JUMP RIGHT
SA-UP ARROR = JUMP UP
SA-DOWN ARROW = JUMP DOWN
SA-TAB = DETAB
Apple /// FEATURES:
The 'OPEN-APPLE' key will modify these keys:
OA-\ = DELETE CHAR LEFT
OA-RETURN = OPEN FOLLOWING LINE
OA-LEFT ARROW = JUMP LEFT
OA-RIGHT ARROW = JUMP RIGHT
OA-UP ARROR = JUMP UP
OA-DOWN ARROW = JUMP DOWN
OA-TAB = DETAB
On the keypad, 'OPEN-APPLE' allows the keys for navigation and misc:
OA-4 = MOVE CHAR LEFT
OA-6 = MOVE CHAR RIGHT
OA-8 = MOVE LINE UP
OA-2 = MOVE LINE DOWN
OA-9 = JUMP UP
OA-3 = JUMP DOWN
OA-7 = JUMP BEGIN
OA-1 = JUMP END
OA-5 = DELETE CHAR
OA-- = CUT SELECTION INTO CLIPBOARD
OA-0 = PASTE CLIPBOARD
OA-ENTER = OPEN FOLLOWING LINE
OA-. = TOGGLE INSERT/OVERWRITE
