!* EMACS "Purifier" and "Compressor". -*-TECO-*-
[toed.xkl.com]DXX:<EMACS>IVORY.EMACS.192, 5-Apr-96 17:43:37, Edit by ALDERSON
Modification history:
9/02/81 188 ECC Added Change PURIFY Format to IVORY Format.
4/05/96 192 RMA Changed naming convention for libraries from :EJ to
ELIB for Tops-20.
The Compressor takes a file of macros such as this one and deletes
comments and whitespace around these comments. It also creates the
documentation strings and the ~DIRECTORY~. Nothing else is changed
(unlike PURIFY). It is intended that macros written for IVORY be
executable without being compressed; i.e. that the compression will
effect no semantic changes on the code.
The Purifier turns a compressed file in the buffer into a file that
can be :EJ'ed, creating the loader macro and other cruft that is
required for proper operation.
A special hack has been implemented to allow PURIFY format libraries
to be compressed in with IVORY libraries. For a library FOO, if
variable PURIFY Library FOO exists and is non-zero, the library will
be treated as a PURIFY library. IVORY knows about a number of common
PURIFY libraries already -- see MM Generate Library.!

!& Compress Buffer:! !S Compress a file of macros, in the buffer.
Removes comments, and makes the documentation and directory strings.
Documentation will be added to the buffer passed in Q8.
Function names will be added to the buffer passed in Q9.!
!*
If > 0, then we are working on the first library
in a sequence of libraries. If it is = 0, we are after the first
library in a sequence.
This first one's ~FILENAME~ is used for the whole object file.
1st ~FILENAME~ Name is set to that filename, for use by the caller.
All other's ~FILENAME~ are turned into "& Compressed foo Library:",
where foo is the filename. (Thus Apropos etc. can show how a file
breaks up into source files.)
& SetUp Compressed Libraries will accumulate code to call the
&Setups that are in the various compressed files, as well as code
to set default variables. It will be prepended to the &Setup
macro in the first library (such a &Setup will be created if one
doesn't already exist).
& Kill Compressed Libraries behaves analogously.
Some syntax notes:
- A macro may have multiple names. These must precede the macro
documentation string. They may be on separate lines if desired.
- FF-CRLFs start macros. If you need one inside a macro, you can
quote the FF with Control-Q (if in a search) or Control-] Control-Q in
general. I.e. ^]^Q^L^M^J.
- Blank macros are ok, e.g. for formatting/commenting source files.
These macros must ONLY contain comments. No macro names, no code...
- We remove all comments and surrounding whitespace BEFORE checking
the major syntax, and thus you may have comments, e.g. before a macro
name.
Special Hack: if we are given a non-zero arg, then the buffer is assumed to
be in PURIFY format, and we will autoload the PURIFY library to perform
the compression.!

Each variable declaration is of the form:
<w> <variable name> "," <w> <comment> ":" <w> <value>
<w> is any horizontal or vertical whitespace.
<value> may be either a number or string surrounded by delimiters.
Sample specification:
Test Foo, * foo fah: 123
Test Oof, * fah foo: |hello there|
Test Num, Random string variable: |123|
String values may be more than one line long.
Quote a colon with Control-] Control-Q.
Quote an Altmode or Control-] with Control-].
Returns a constructed macro that will call .C for each of
these variables specified. The macro will not contain any redundant
setups, i.e. if a variable has been previously recorded and its setup
macro returned, it won't be included in the macro returned.!

!Generate Library:! !C Make one ELIB file from several source files.
Takes desired name for ELIB file as first string argument, followed by
the names of the input files. A null string argument
(altmode-altmode) ends the argument list.
The input files are all compressed and purified together. You are
told as each is compressed etc. However, if $Silent Running$ is
non-0 nothing is printed. (Good for ^Z ^Ping.)
Filename defaulting is sticky; input FN2's default to >; the output
FN2 to ELIB.
The defaults are restored after the macro is finished.
~FILENAME~ is taken from first file's ~FILENAME~. It must have one.
Other ~FILENAME~s are turned into "& Compressed foo Library:"s.
All "hidden" & SetUps (i.e. not of same name as object ~FILENAME~)
will be accumulated, and code to call them will be inserted at the
beginning of the first file's &Setup. If that file has no &Setup,
one will be created.
Also, the &Setup documentation will have a record (as part of its
documentation string) telling who generated the object, when, and
from what source files.
All "hidden" & Kills (i.e. not of same name as object ~FILENAME~) will
be accumulated and called from the main &Kill in a similar manner.
Note that all source libraries are always compressed, no COMPRS files
are created, and the destination library is always created.
For a given FN1, if variable PURIFY Library FN1 is non-zero, then
the file is assumed to be a PURIFY library.!

If Test Load Sets Keys is non-0 (the default) and if the macro is an

put it on any key. (any better?)
If a positive NUMARG is given, compressed macros are put into
MM-variables when differences are found. Negative NUMARG means
make uncompressed, without checking difference.

!Compress File:! !C Generate a PURIFY style COMPRS file from a source file.
STRARG1 is the COMPRS file.
STRARG2 is the source file. Filename defaulting is sticky left to
right.
(The second filename of the COMPRS file MUST be COMPRS.)
This command is useful for creating COMPRS files so people using the
standard EMACS purify package can GEN them into their libraries.
One tricky thing: it always leaves ^Ls on their own lines, even if
not there to begin with, since PURIFY will change CRLF ^L to ^L,
and CRLF CRLF ^L to CRLF ^L.!

!Change PURIFY Format to IVORY Format:! !C Changes Buffer to IVORY Format.
This function is a good starting place -- but you will need to finish the
conversion by carefully checking the code yourself. A warning message to
this effect, and some hints, will be printed.
The conversion warning message is suppressed if you supply a numeric argument.!
!* This function was written by P.J.Gergely of the Canadian Defense Research!
!* Establishment Atlantic. ECC@MIT-AI added the warning message!

ftNote that this is approximate -- you should check the result carefully,
especially for conversions that can only be done by understanding the
semantics:
1. PURIFY files sometimes have comments in the middle of string args.
Those will be ok in IVORY if compressed, but not if run uncompressed.
2. Similarly, " or ' in comments should be avoided if you want to run the
code uncompressed.
3. Line indentation within string args will be wrongly retained. You
will have to remove it by hand.
4. PURIFY compresses n successive CRLFs into just one, which again will
require you to correct any within string args.
Also, things like 1u1 2u2 will become the uglier 1u12u2, which you may want
to correct.
We suggest that you write the new IVORY source to a file different from the
PURIFY source, then compress both files -- using the PURIFY function
& Compress File and the IVORY function Compress File -- and then compare the
resulting COMPRS files.
