Generate some EMACS libraries with IVORY.

Browse Source 
Except IVORY, there's also WORDAB and TMACS.  IVORY needs go be
generated with itself, so include the :EJ for bootstrapping.

!* -*-TECO-*- *!
!* This is the EMACS library TMACS. Note that it requires the purifier in
* EMACS;IVORY -- not the one in EMACS;PURIFY.
* Note too that when making EMACS;TMACS :EJ, you need to compress this
* source and also TMUCS >. You can use M-X Compile, since this file
* has a local Compile Command, which leaves the object in ECC;XTMACS :EJ.
* The documentation strings starting with "I" indicate internal subroutines
* not intended to be called from outside TMACS.
* In general, for easy abstracting (Abstract File), the most generally
* useful stuff should be at the top. And, documentation should be filled
* with a Fill Column of 70. You can use (local to this file) M-X Edit TMACS
* Documentation.

TMACS
!Type Mailing List:! !C Prints an entry in ITS mailing list file.
This works on any ITS machine. (.MAIL.;NAMES > has the ITS mailing
lists.)
For instance, M-X Type Mailing Listbug-random-program<cr> will show
you who is on the bug-random-program mailing list on your machine.
If string argument is of form <name>@<site>, <site>:.MAIL.;NAMES is
used. Only final @ indicates site, so you can do something like:
M-X Type Mailing List$BUG-@@AI$
A numeric argument limits depth of recursion on EQV-LIST members.
(Default depth is 3.)
<name>@<site> entries in EQV-LIST are not followed.
Prints "Done." when done, since it sometimes is slow. Giving a
pre-comma numeric argument inhibits done-printing, for use as a
subroutine.!

!^R Select Buffer:!!Buffer Menu:! !^R Display information about all buffers.
A recursive edit level is entered on a list of all buffers.
On exit the buffer on the current line is selected.
Point is initially on line of current buffer and space will exit (like
^R Exit), so this is very much like List Buffers but
combines listing with selecting in a way that does not involve
much typing or redisplay. * means modified, - means modified and not
auto-saved, and . means current buffer.

!^R Draw Vertical Line:! !^R Draws from current hpos, not inserting.
Line drawn only in current window, and column printed at base of line.
This only works on ITS machines.
If any ARG given, is displacement from current hpos. E.g. -1 means
draw line through position one column left.
If C-U is specified, together with an ARG then ARG is an absolute
column. E.g. M-3 C-U as argument makes line in column 3. But
M-3 as argument makes line in column 3+current_column.!

!^R Auto Fill Comments:! !^R Refill the comment and its continuations.
To handle comment starts (or parts of them) that are repeated, e.g.
";;; " in Lisp, or perhaps "/*** " in Pl1, it will treat a duplicated
last character of the comment start or begin as part of the comment
beginning when merging comment lines.!

!^^ TMACS Error Handler:! !S Q..P: handles TECO errors.
If first character typed is "?" then Backtrace is called.
A space makes us exit, with no action.
If option variable TMACS Error Dispatch is non-0, some other
characters may be typed, in any order, ending with a space (no
further action) or "?" (enter Backtrace):
B Display the offending buffer.
D Directory Lister is run.
W Who caused this? -- type function's name.
Typing HELP character describes the error handler.
Quits are not handled at all unless the variable Debug is nonzero.
That is so a quit will cause the buffer and modeline to be
restored and redisplayed immediately.
A QRP error (q-register PDL overflow) will cause automatic partial
unwinding of the q-register PDL if you type anything but Space.
You can thus enter Backtrace etc.!
m(m.m& Declare Load-Time Defaults)
TMACS Error Dispatch,

MARK is set before inserted name.
Handles bit and char prefixes, e.g. Meta-, ^X, unless:
Given a numeric argument, gets the name of a prefixer (e.g. metizer).
Impure-strings that are uncompressed macros are handled if their names
are present at the beginning of the macro.
Some characters run standard builtin functions whose names are found
in the BARE library. These work fine. Others which are not found
just insert their key names, e.g. Meta-O.!

!Lock File:! !C Lock current buffer's file.
"Lock" the file in the current buffer by creating FN1 *LOCKED*.
Will complain if FN1 *LOCKED* already exists, and will tell who has it
locked (since FN1 *LOCKED* contains that person's xuname).

!Flush Variables:! !C Kill some variables specified by search string.
Kill variables whose name contains the string argument.
String argument actually is a TECO search string, and so you can flush
variables containing "foo" OR "bar" by using the string argument
"foobar".
The list to be flushed is typed, asking Y, N, or ^R?
N means abort, ^R allows editing of the list.!

!* Now have to figure enough of variable name to be unambiguous:

* mistakes -- having to do with variables whose names are prefixes of others.
* But anyhow...:
* The buffer has a list made by List Variables which includes a description
* of the value, and we cant really tell where a long variable name ends and
* the value description begins. We will find out by trying the first 25
* letters, which is definitely part of the name, and checking if that is
* ambiguous. If so, we append the next word of the line, which must be
* another part of the variable name, and again check for ambiguity. The
* variable name will eventually be unambiguous.

!& Kill Prefixed Variable Names:! !S Kill variables if names STRARG-prefixed.
STRINGARG is prefix for variable name. E.g. doing:

!* that range of buffer!

!& Insert Prefixed Variable Names:! !S Insert some variable names.
String argument is prefix for variable name. One variable name to a
line.
E.g. m(m.m& Insert Prefixed Variable Names)MM  will insert the names
of all variables whose names start with "MM ".

!Abort Recursive Edit:! !C Abnormal exit from recursive editing command.
The recursive edit is exited and the command that invoked it is
aborted.
For a normal exit, you should use ^R Exit, NOT this command.
The command can put a string in Abort Resumption Message
to tell the user how to resume the command after aborting it.
If the option variable Less Asking is non-0, no message will be
printed, and you will not be asked for confirmation.!
