INSTALLATION
The NULL: device must be mounted to be able to use the EXECUTE command.
This is so EXECUTE works even if the console window goes away. Otherwise,
simply put DME in an accessable location (usually C:). Put the dme.icon
file in the same directory as DME if you want to access the application
from the workbench (dme.icon is not needed if accessed from a CLI or shell).
People appear to have problems using the EXECUTE command when DME is run
from the workbench. I have no solution yet.
The CONFIG program may be used to configure the default window placement,
size, and color. This program modifies the executble:
config c:dme (or wherever you have the executable)

OVERVIEW
See REVISIONS section for revisions. DME is an editor designed mainly for
programmers. Although it is not a word processor, it does include many
word processing features such as Word-Wrap and automatic paragraph
formatting. Here is a quick 'features' list:
-control language based on a rich command set accessed manually
or via arbitrary mapping of keys. (Every key may be mapped to 128
different things via qualifier and mouse keys)
-General variables, reference macros as variables, ENV: enviroment
variables (1.30C and beyond).
-fast visual response (it scrolls quickly)... even faster when
BlitzFonts or similar text speedup utilities are installed.
-title-line statistics showing your current position in the file,
file name, whether the file has been modified or not, etc...
-Multiple Windows, ability to iconify windows
-Word Wrap and automatic paragraph formatting.
-ability to map any KEY or MOUSE BUTTON combination.
DME has been designed to allow easy expansion, and I intend to make many
future improvments. It has not been designed for user friendliness, but is
straight forward if you read this document [care]fully.
DME can take any number of arguments. Any argument without a '-' in front
of it is considered to be a file. Normally, DME will automatically SOURCE
two script files, S:.EDRC, and the .EDRC in your current directory. These
files do not have to exist. These script files usually contain mappings
and do things (for example, turn on savetabs).
FLAGS:
-ffilename -source this script file instead of .EDRC
-b -normally when multiple files are specified,
DME opens them with small windows. This opens
them with normal sized windows.
-tN -Open the window on scan line N
-lN -Open the window offset N scan columns
-wN -Make the window N pixels wide
-hN -Make the window N pixels high
II
KEYMAPPING
MOUSE BUTTONS:
The mouse buttons and combinations thereof may now be mapped. The
default mappings for the mouse buttons are as follows:
Left-button: Move cursor to current mouse position
Right-button: Iconify window
Left-button held down while moving mouse tracks the cursor
The iconification features:
-Remembers original window size and placement
-Remembers placement of iconified window when you re-iconify later.
Currently, you will crash the machine if you run out of memory and DME
is unable to open the icon window or original window, so be careful.
see below for mapping the mouse buttons and mouse movement.
KEYBOARD:
The rest of the Functional interface for DME is based on key/mouse mappings
and a rich command set. Unlike other text editors, any non-qualifier key
in DME may have any meaning whatsoever. It just so happens that the
default keymappings assign such things as the (return) key to the RETURN
function, the (up) key to the UP function, etc... Keys are named by their
keycap labels with the following exceptions:
the name for Back-Space is BS
the name for numeric keypad keys are prepended with an NK, except for
the Enter key which is named 'ENTER'.
The four cursor control keys are labeled UP, DOWN, LEFT, and RIGHT
The three mouse buttons are labeled RMB, MMB, and LMB.
NOTES:
The normal Amiga mouse has only two buttons, the Left and the Right
mouse buttons (LMB, RMB). A properly installed three-button mouse
is also supported.
You must type commands in lower-case, except for text, which can be
either lower or upper case, and for upper-case alpha keys when
specifying keymaps (i.e. A and s-a are the same key). The
exception is the AMIGA qualifier key, which uses 'A' instead of
'a'(Alt).
Each key may be qualified with any combination of CTRL, ALT, SHIFT,
AMIGA, or any of the MOUSE buttons. With 6 qualifiers (7 if your
mouse has a middle button), you can assign up to 64 (128) different
maps to each physical key on the keyboard.
The CAPS-LOCK, when lit, is equivalent to SHIFT only for Alpha keys.
The AMIGA-ALT (aA) combination isn't very usable since Intuition
uses the sequence to duplicate a Mouse SELECT. Other AMIGA
sequences are used by intuition for mouse movement and other things.
Some other qualifier combinations may not be usable due to other
special sequences.
Some keys must be mapped by their lower-case keycap. That is, to
map the '>' key (USA keyboard), you specify shift dot (s-.)
***EXAMPLES:***
tab tab
a-a ALT a
A-a AMIGA a
sA-a SHIFT AMIGA a
s-tab SHIFT tab
c-tab CTRL tab
ac-? ALT-CTRL ?
s-f5 SHIFT F5
nk0 Numeric Keypad 0
cs-nk0 CTRL SHIFT Numeric Keypad 0
L-lmb Left Mouse button pressed
L-mmove Mouse moved while left mouse button held down
LR-lmb left mouse button hit while right mouse button held down
s-. shift . ('>' for USA keyboards)
***************
MAPPING MOUSE BUTTONS
Mouse buttons serve both as QUALIFIERS and as KEYS. Thus, you can map
both normal keystrokes which require a mouse button to be held down:
map L-a ((left button and an a))
as well as the mouse keys themselves:
map L-lmb ((left mouse key))
note that you had to specify the left mouse button down qualifier L as
well as the left mouse button LMB.
If you map the left mouse button, and also map a sequence such as left
mouse button + a:
map L-lmb tomouse
map L-a ((hello))
Note that the first mapping will always get executed even if you
intended L-a (that is, BOTH mappings would get executed). In order
to avoid confusion you might want to UNMAP the system default mapping
for the right mouse button (mapped to ICONIFY) if you wish to apply
combinations to the right mouse button.
MOUSE MOVEMENT is mapped with one or more mouse qualifiers (L, R, M),
plus 'MMOVE' for the key. That is:
map LR-mmove ((moving the mouse with both buttons held down))
Or how bout capping the characters under the mouse while moving the
mouse?
map LR-mmove (tomouse if cl (tlate -32))
DEFAULT KEYMAPPINGS:
All Printable Ascii keys mapped to their ascii equivalent. BS, DEL, UP,
DOWN, LEFT, RIGHT, TAB, S-TAB, and ENTER are mapped properly. These are
the default system keymappings.

COMMAND SEQUENCES
DME has a rich command set which allows you to embed commands within
commands, or specify multiple commands in a row. A command consists of a
KEYWORD followed by a FIXED number of arguments (0, 1, 2...). The argument
delimeter in DME is a SPACE. Therefore, to embed strings containing spaces
as a single argument, you must surround the string with (string)
(backsinglequote-string-singlequote). TEXT to be written as if typed is
also specified via a string in backquote-quotes. For example:
right right (hello) right right (hello) enter down
map f4 (right right) map f5 (left left)
map f4 ((hello))
Reiterating (because this is important!)... If a command expects ONE
argument, then it really does expect a single argument, and any remaining
arguments are thought to be the next command... so:
map f4 right
-right is only one word, so no need
for ().
map f4 (right right)
-we want to map f4 to two rights... we
need the () or the second right will
not be part of the map.
map c-del (repeat cright del)
-this is already implimented as REMEOL,
but shown here for clarity.
Some arguments will eventually be fed through the command interpreter more
than once. The MAP command is a good example. When you execute a MAP
command, the first run through the command interpreter installs the map
string minus a set of quotes. So, if you want to specify text, you must
enclose the text in two sets of ((text)) because the map string gets passed
through the command interpreter again when you hit the mapped key. Here
are some more complex examples:
map f4 (right right (hello) left left) *RIGHT*
map f4 right right hello left left *WRONG*
map f4 (map f4 ((hello)))
-the first time you hit F4, it's command
is to re-map itself to the TEXT (hello).
(gads!).
map c-i (repeat tr (( )))
-example of how to embed a space in a
map and repeat (goes through command
interpreter three times!).
An easy way to fool around executing commands or making maps is either to
use the ESC key (which enters command mode), or a-S (alt-shift-s), which
EXECUTES the current DME line that the cursor is on.... so you can use DME
to edit and test your new keymappings.
STRING VARIABLES
String variables are replaced with their contents. Three specification
forms are allowed:
$varname - varname can only consist of a-z,A-Z,0-9,-,_
$(varname) - anything not containing a '(' or ')'
$`varname' - anything not containing a '`' or '''
Two special variables exist:
filename - the current filename
scanf - the current scanf'd string (see SCANF below)
lineno - the current cursor line number (1 .. N)
column - the current cursor column number (1 .. N)
Other variables cause a search of three variable domains to find the
contents. For example, if you give $DMEFONT:
(1) An Internal variable named DMEFONT is searched for. Internal
variables are case sensitive. (see SET, UNSET)
(2) An Enviroment variable name DMEFONT is searched for. Enviroment
variables are NOT case sensitive. (see SETENV, UNSETENV). The
1.3 ENV: is used.
(3) A DME keymap or menu definition named DMEFONT is searched for.
This allows you to say something like $sa-tab to insert the
contents of the shift-alt-tab keymap. (see MAP, UNMAP, and
MENU oriented commands).
The reason for the other two forms of variable specifiction is to allow
one to access strangely named variables (with puncuation and other crap).
SPECIAL NOTE: What is wrong with this command?
repeat 100 (first ($myvar))
What is wrong is that $myvar is evaluated BEFORE the repeat is
executed. myvar might contain characters that would confuse the
command specification when. That is, if myvar contained a '(' you
could get something like: repeat 100 (fist ((()) which is obviously
incorrect. By using \ you can cause $myvar to be evaluated at
loop-execution time rather than before:
repeat 100 (first (\$myvar))
These kinds of problems can also occur when you do keymaps... you
probably do not want to evaluate the variable at keymap-entry time,
but rather would want the variable evaluated at keymap-execution time.
On the otherhand, this is perfectly allowable:
set x (tlate +1)
repeat 100 ($x)
Which executes the command (tlate +1) 100 times... By NOT surrounding
the variable with parens (depends on the situation), the variable is
executed rather than inserted as text.
SPECIAL CHARACTERS
^ is used to introduce a control character. For example, ^c would
embed a control-c. You cannot embed c-@ (ascii code 0).
backslash \ is used to override special meanings. The next character
is overriden.
map c-a ((^l)) -map control a to produce a control l
map c-a ((\\\^l)) -map control a to produce a "^l". The first
\ overides the second, and the third overides
the ^.

-------------------------------------------------------------
------------- More Info on Complicated Commands -----------------
-------------------------------------------------------------
MENUOFF/ON -This command will enable/disable menus. Users
who have a whole bunch of MENUADD commands in
their .EDRC should note that disabling menus at
the beginning will speed up the MENUADD commands.
Then reenable menus at the end. These calls are
stackable in that if you call MENUOFF, say, twice,
it will take two MENUON commands to restore
menus. The reverse is not true.
CTAGS (c-[) -(1.30B and beyond) Compatible with Aztec's CTAGS
program. This command searches for the subroutine
name under the cursor in the associated tags file
("tags" in the directory holding the file currently
being edited). Also, the file "tags" in directories
specified by the special DME path (see ADDPATH and
REMPATH) will be searched.
If the tag is found, it loads the file the subroutine
resides in if neccesary, then WindowToFront()'s the
window, ActivateWindow()s it, and GOTO's the line
where the subroutine starts. The search within the
source file is anchored to the left column. If the
file is already loaded, it is not reloaded.
This enables a programmer to quickly trace subroutines
over an arbitrary number of files.
The tags file contains one or more lines of the following
format:
subroutine-name file-name /^search-pattern
(that's a slash and a carrot, then the pattern)
-- EXAMPLE of 'TAGS' file:
setpen cmd1.c /^setpen(
do_up cmd1.c /^do_up(
--
SPECIAL NOTE: CTAGS will work even if you are not in
the directory containing the file. You can thus place
a tags file in the directory containing the files it
references, and the filenames WITHIN the tags file need
not be a full path.
REF (c-]) -(1.28d and beyond). This is a very powerful new
command that allows you to bring up a reference to
a keyword with a single keystroke. This is useful for
programmers who have on-line documentation or fully
commented include files. DME opens a window just big
enough to fit the reference.
NOTE: The new CTAGS command may be more suited to
your application.
The reference keyword is the alpha-numeric string
currently under the cursor. REF will search the
file DME.REFS in the directories listed by the
special DME path (see ADDPATH and REMPATH). The
file must be built by the user and each line has the
following format:
(keyword) (nolines/endstring) (file) (searchstr/##seekpos)
Surrounding the keywords with `' or () is optional if
the keyword does not contain spaces.
keyword -keyword under cursor
nolines/ends-either a number (the number of lines
in the reference) or a string denoting
the end of the reference when found.
file -the file containing the reference
material
searchstr/##-search string in file that indicates
the beginning of the reference, or
two hashes (##) and the seek position
in decimal (like ##2343). The latter
method is used mainly for reference-
generator programs.
Upon finding a successful keyword match the specified
file is openned and the seach string searched for. If
a seek position was specified no search is made and a
seek is made to the beginning of the reference. If
found, the indicated number of lines (if a number
is specified for <nolines/ends>) or until a match with
the endstring (if a string was specified) will be
placed in a temporary file and a new DME window
brought up. The temporary file is then deleted.
When looking for matches, the compare is anchored at
the beginning of each line in the file. Thus, any
spaces in front of the string in the file must be
duplicated.
T: must be assigned to a temporary directory, usually
RAM: See the included example DME.REFS file. The
most common things referenced are the autodocs and
commented include files.
Some modification of the included DME.REFS.* files may
be required due to differences in include file and
autodoc format.
SCANF ctlstr -This is equivalent to the C scanf() function with the
restriction that only one conversion is allowed, that
conversion being a string. Thus:
scanf %s will place the string under the
cursor in the variable $scanf
scanf %4s The first four chars of the string.
scanf %[0123456789]
will scan the string while it contains
specified chars (e.g. scan a number)
scanf %[~,] will scan the string until it finds
a ','.
The variable $scanf may be used as an argument in any
command. Example: (insfile $scanf).
NOTE: If using $scanf in a macro, you probably want
to precede it with a \ to prevent it from being
evaluated at macro-creation time.
REPEAT N arg -Repeat (arg) N times. Apart from being a number, N
can also be one of:
line Current line # (lines begin at 1)
lbot #lines to the bottom, including current line
cleft column # (cols begin at 0)
cright #chars to eol, including current char under cursor
tr #char positions to next tab
tl #char positions to next back tab
Certain commands can abort a REPEAT loop.
Specifically, any FIND[R], NEXT[R], or PREV[R] in which
the search string is NOT found will abort a REPEAT.
Most operations which can go out of bounds, such as
UP, LEFT, RIGHT, DOWN, also abort a repeat.
Specifying -1 as N causes REPEAT to go on forever
(well, actually, 0xFFFFFFFF times) or until an abort.
IF [!]condition arg
WHILE [!]condition arg
IFELSE [!]condition arg else arg
If the specified condition is true, execute the argument. For
WHILE, the argument is executed until the condition is false
(be careful!).
the optional '!' inverts the logic.
Conditions:
# if toggle entry # is SET. there are 256 toggles (0..255)
t if On line 1
b if On last line
l if At column 0
r if At end of line (spaces below and beyond)
m if Text has been modified
i if in insert mode
x[<=>]# if column position (starts at 1) is (any OR combo of
<, =, or >) than some number. Example: x<=20
y[<=>]# if Line number (starts at 1) is (same as for x)
cl character under cursor is lower case alpha
cu character under cursor is upper case alpha
ca character under cursor is alpha-numeric
cn character under cursor is numeric
c[<=>]# character under cursor is ascii code # (# in decimal)
optional conditionals as in 'x' and 'y'.
cb cursor within a block
Example: simulating an insert mode toggle: ALT-i (not CTL-i)
map a-i (ifelse 0 (toggle 0 insertmode OFF) (toggle 0 insertmode ON))
Example: while lower case, map to upper case and move right.
map c-U (while cl (tlate -32 right))
Example: Search/Replace all of text.
map c-R (escimm (findstr ) escimm (repstr ) repeat -1 nextr)
if c<32 ((char under cursor is smaller than 32))
if c<>32 ((char under cursor is not equal to 32))
while !b down
IV
FILE PARTICULARS
No Matter what you set internal tabs to, tabs in disk files will be 8.
This allows you to use your favorite tabs stops (mine are 4) and still
have your disk files compatible with TYPE, a printer, etc... DME by
default doesn't bother to optimize when writing out files and simply uses
spaces. If you (SAVETABS on) before saving (or in your S:.EDRC, etc...),
DME will attempt to optimize the file by placing TABS in appropriate
places. DME will not place any TABS after the first single, back, or
double quote is encountered in a line. If this does not cover every
situation in your particular application that you want to be *sure* no tabs
will occur in sensitive sections, then you should not use (SAVETABS on).
It should be noted that since DME removes spaces at the end of the line,
editing UUENCODED ascii files will not work for uuencoded lines which end
with a space. The nominal fix is to add an extra character after each
uuencoded line (anything) in the proper column, which is ignored by the
UUDECODE program.
The command to save the current document under the default name is SAVEOLD,
*not* SAVE. SAVE is not a valid command. This is to prevent people who
have not read the documentation from assuming 'save' takes an argument (and
screwing up their work). SAVEOLD does NOT take an argument, SAVEAS does.
SAVEOLD/SAVEAS do not automatically backup the destination file. If you
are working in an enviroment where you are worried about ensuring a viable
copy can be recovered if your Amiga crashes in the middle of the save, you
can write a macro to save the file into two places. Usually, people backup
their working disks so this is not neccesary.
Workbench Support: If DME is run from the workbench, it will automatically
construct an icon file when you save a document. If run from a CLI, no
icon file is generated.
V
WORKBENCH SUPPORT
DME V1.26 and beyond support the workbench in the following way: (1) you
can click on the DME icon to bring up DME with the file "unnamed". (2) you
can select one or more standard ascii documents which have DME as the
default tool. If DME has no knowlege of a text icon, it uses its own.
Command line arguments are passed to DME via the tooltypes entries for
DME's application icon or via individual document icons. The following
format is used: (This is a hack, no?)
ARG=flag
See the OVERVIEW section for allowed flags. Only one argument per line
is allowed (sorry). The tooltypes for the application icon are
processed first, then the tooltypes for each document icon are
processed before each file is loaded.
ARG= -t10
ARG= -l10

REVISION SUMMARY
V1.38
- Removed fix in 1.37, use '1.4libpatch' if running under 1.4A16.
- FIXED AREXX BUG... DMe would crash if ARexx was installed for
V's 1.37 and 1.36
V1.37
- 1.4a16 crashes on OpenLibrary() where the library does not
exist. Doesn't try to open arex if running under 1.4
(for now, this is a temporary stopgap)
V1.36
-Removed dres.library IPC. Removed dres.library requirement. (ARexx IPC
still in of course). Source now compilable under Lattice C and Manx C.
V1.35a
-can change block pen now and DME updates the title using the correct
color.
V1.35
-Bug in 1.34 fixed, would only work if dres.library was installed
OOOPPS.
V1.34
-New variables $fpath and $fname have been added. $fpath is the path
part of the current filename, including trailing / or : (if any).
$fname is anything after that. For example:
FILE fpath fname
s:.edrc s: .edrc
blah blah (path = "")
/poof / poof
V1.33 RELEASE
-You can now run <nil: >nil: DME and close the console window that
you ran it from. The execute command now requires the NULL: device
to be mounted or an error will occur.
-space -> tab conversion does not take place after the first control
character (<32), as well as the first quote ("), open paren ((), or
single quote (') that it didn't before.
V1.32 (small fixes)
-Fixed workbench bugs, DME would exit if it could not find the
executables disk object. No longer does so.
V1.31 RELEASE
-Added new variables $lineno and $colno
-Added CD command, ARPLOAD automatically CD's to DIR part of
requester.
-Added IPC support (my own ipc)
-Fixed bug in BMOVE (when the source block is an entire file)
V1.30C LIMITED
-MAJOR! Macros, Internal variables, and ENV: enviroment variables
may be specified with $varname, $(varname), or $`varname'.
-New commands: SET, SETENV, UNSET, UNSETENV (variable support)
-REFS window bug fixed I hope (made window slightly too small).
-SAVE[S]MAP bug fixed for space mappings
-CTAGS doesn't modify the window title if the window is iconified
(allows you to make the following map: map <somemap> (iconify ctags)
V1.30B Limited release
-Kim fixed a bug in splitpath
-added CTAGS command... support for Aztec's CTAGS program
-added ADDPATH command... special directory paths for DME
-added REMPATH
REFS no longer searches fixed directories, but looks at the
ADDPATH directories. CTAGS also looks at the ADDPATH
directories. CTAGS supports arbitrary directory specifications
and is intelligent about where to look for the TAGS file.
V1.30 RELEASE
-a couple small bugs fixed
-fixed text bug that sometimes overwrites the right border
-added new commands
SETFONT (for all of text, static fonts only)
IGNORECASE (for searches)
-added new commands (AREXX support, Kim DeVaughn)
RX, RX1, RX2
-added new commands (by Kevin Speghetti)
PUSHMARK, POPMARK, SWAPMARK, PURGEMARK block marker stack
PING, PONG text markers (0-9)
note: block marks on the stack, ping and pong, do not track text
changes (bug).
-Many commands will now work while the text window is iconified
without having to uniconify it.
V1.29E
-Fixed low memory bug in do_bomve() again.
-Fixed arp file requestor problems.
-added ARPINSFILE command.
V1.29D
-Fixed low memory bug in do_bmove()...
V1.29C
-highlighted icon window if file modified
V1.29B
-INLINE FILENAME:
added $filename variable. $scanf and $filename can now be embedded
anywhere on the command line.
- ^x added (control-character), so you do not have to embed actual
control characters in your macros.
- \ overide added (\^x) produces "^x" instead of control-x, etc...
V1.29 RELEASE
-Foreign keyboards supported better.
-Iconify window is activated rather than not activated.
-can keymap keys which normally produce nothing.
-blocks are displayed in a different color
-can now move/copy across windows
-can now resize window while file loading
-new commands ARPLOAD ARPSAVE (uses ARP filerequestor if arp.library)
MENUADD MENUDEL MENUDELHDR MENUCLEAR MENUOFF MENUON
minor bugs fixed, major remodeling of the source (this is what I
use my vacation for!)
menus: the right mouse button may be mapped only if there is no
menu, Else is used as the menu selector. NOTE! It is much faster
to surround a set of MENUADD commands in a source file with
MENUOFF at the beginning and MENUON at the end. You can also specify
menu items as macros in other commands (example: project-save)
V1.28h SMALL RELEASE references work better
V1.28g SMALL RELEASE Fixed NK0 bug in 1.28f plus keymap problems in 1.28f
V1.28f RELEASE
Fixed macro bug created in 1.28e... could not specify macros on the
command line.
V1.28e INTERNAL/BETA
New Commands: REF (c-]) -cross reference the word under the
cursor and bring up a new window
containing a description for that
word. See docs above.
-The keymapping has been fixed and should now work on any foreign
keyboard.
-MAJOR ADDITION: () may be used instead of `' to enclose commands.
One can enclose the other ... that is, to get the "'" character you
can say (this is a charlie's day).
V1.28c RELEASE
New Commands: CHFILENAME -change default filename for a window
RECALL (c-esc) -recall command line (e.g. you make a
mistake). Must be used from a keymap,
default is c-esc.
SCANF -C scanf (single string only). Extract
strings from the text for use in any
arbitrary command.
Command Parser: $scanf -as an argument by itself is recognized
to be the extracted string from scanf.
Currently, the variable name (after
the dollar) can be anything since only
one variable exists, but use '$scanf'
for future compatibility.
-Many Bug fixes (mainly benign bugs)
-^C (CONTROL C) now recognized when typed in a window. c-c is mapped
to () = no action.
-Please look at the revised default keymappings listed in these docs.
