\fIELLE\fR (ELLE Looks Like Emacs) is an Emacs clone for
|
|
.MX .
|
|
ELLE is not full Emacs but it has about 80 commands and is quite fast.
|
|
.SP 0.5
|
|
.SS "Key bindings"
|
|
.SP 0.5
|
|
.PP
|
|
\fIMined\fR only has a small number of commands. All of them are either of
|
|
the form CTRL-x or are on the numeric keypad. Emacs, in contrast, has so
|
|
many commands, that not only are all the CTRL-x commands used up, but so
|
|
are all the ESC x (escape followed by x; escape is not a shift character,
|
|
like CTRL). Even this is not enough, so CTRL-X is used as a prefix for
|
|
additional commands. Thus CTRL-X CTRL-L is a command, and so is CTRL-X K.
|
|
Note that what is conventionally written as CTRL-X K really means CTRL-X k.
|
|
In some contexts it is traditional to write CTRL-X as ^X.
|
|
Please note that they mean the same thing.
|
|
.PP
|
|
As a result, many Emacs commands need three or four key strokes to
|
|
execute. Some people think 3-4 key strokes is too many.
|
|
For this reason, Emacs and ELLE allow users to assign their own key bindings.
|
|
In ELLE this is done with \*(OQuser profiles.\*(CQ A user profile is a file listing
|
|
which function is invoked by which key stroke. The user profile is then
|
|
compiled by a program called ellec into binary form. When ELLE starts up
|
|
it checks to see if a file .ellepro.b1 exists in $HOME. If it does, this
|
|
file is read in and overrides the default bindings.
|
|
.PP
|
|
A user profile that simulates the \fImined\fR commands fairly
|
|
well is provided.
|
|
Its installation is described later. If you have never used Emacs,
|
|
it is suggested that you use the \fImined\fR profile.
|
|
If you normally use Emacs, then
|
|
do not install the \fImined\fR profile. You can also make your own using
|
|
\fIellec\fR.
|
|
There is no Mock Lisp.
|
|
.PP
|
|
ELLE has a character-oriented view of the world, not a line oriented
|
|
view, like \fIed\fR.
|
|
It does not have magic characters for searching.
|
|
However, you can use line feed in search patterns.
|
|
For example, to find a line consisting of the three characters
|
|
\*(OQfoo\*(CQ all by themselves on a line, using the mined
|
|
bindings (see below), use the pattern: CTRL-\\ CTRL-J f o o CTRL-\\ CTRL-J.
|
|
The CTRL-\ means to interpret the next character literally, in this case it
|
|
is CTRL-J, which is line feed. You can also search for patterns involving
|
|
multiple lines. For example, to find a line ending in an \*(OQx\*(CQ followed by a
|
|
line beginning with a \*(OQy\*(CQ, use as pattern: x CTRL-\ CTRL-J y.
|
|
.SS "Mined Key Bindings"
|
|
.PP
|
|
These are the key bindings if the binary user profile, \fI.ellepro.b1\fR,
|
|
is installed in $HOME. The ESCAPE key followed by a number followed by a
|
|
command causes that command to be executed \*(OQnumber\*(CQ times. This applies
|
|
both to control characters and insertable characters. CTRL-X refers to a
|
|
\*(OQcontrol character.\*(CQ ESC x refers to an escape character
|
|
followed by x.
|
|
In other words, ^X is a synonym for CTRL-X.
|
|
^X Y refers to CTRL-X followed by y. To abort the current command and go
|
|
back to the main loop of the editor, type CTRL-G, rather than CTRL-\\.
|
|
.PP
|
|
Only a few commands are of the form CTRL-X Y. All of these are also
|
|
bound to CTRL-X CTRL-Y, so you can hold down CTRL and then hit X Y, or
|
|
release control after the X, as you prefer.
|
|
.PP
|
|
The key bindings that are not listed should not be used.
|
|
Some of them actually do things.
|
|
For example, the ANSI escape codes ESC [ x are bound
|
|
to ^X Y for a variety of y.
|
|
.PP
|
|
Some commands work on regions.
|
|
A region is defined as the text between the most recently set mark
|
|
and the cursor.
