The asq (ask) function is a command line utility for extracting information
from the OpenAxiom databases. It understands how the data is stored and can
retrieve all data associated with Categories, Domains, and Packages.

It used to look for the databases in [[$AXIOM/../../share/algebra]]
which was a NAG modification of the original location
but has been changed to search [[$AXIOM/algebra]] as originally designed.

\section{Database structure}
In order to understand this program you need to understand some details
of the structure of the databases it reads. OpenAxiom has 5 databases,
the interp.daase, operation.daase, category.daase, compress.daase, and
browse.daase. The compress.daase is special and does not follow the
normal database format.

\subsection{KAF File Format}
This documentation refers to KAF files which are random access files.
NRLIB files are KAF files (look for NRLIB/index.KAF)
The format of a random access file is
\begin{verbatim}
byte-offset-of-key-table
first-entry
second-entry
...
last-entry
((key1 . first-entry-byte-address)
 (key2 . second-entry-byte-address)
 ...
 (keyN . last-entry-byte-address))
\end{verbatim}
The key table is a standard lisp alist.

To open a database you fetch the first number, seek to that location,
and (read) which returns the key-data alist. To look up data you
index into the key-data alist, find the ith-entry-byte-address,
seek to that address, and (read).

For instance, see src/share/algebra/USERS.DAASE/index.KAF

One existing optimization is that if the data is a simple thing like a
symbol then the nth-entry-byte-address is replaced by immediate data.

Another existing one is a compression algorithm applied to the
data so that the very long names don't take up so much space.
We could probably remove the compression algorithm as 64k is no
longer considered 'huge'. The database-abbreviation routine
handles this on read and write-compress handles this on write.
The squeeze routine is used to compress the keys, the unsqueeze
routine uncompresses them. Making these two routines disappear
should remove all of the compression.

Indeed, a faster optimization is to simply read the whole database
into the image before it is saved. The system would be easier to
understand and the interpreter would be faster.

The fastest optimization is to fix the time stamp mechanism
which is currently broken. Making this work requires a small
bit of coordination at 'make' time which I forgot to implement.

\subsection{Database Files}

Database files are very similar to KAF files except that there
is an optimization (currently broken) which makes the first
item a pair of two numbers. The first number in the pair is
the offset of the key-value table, the second is a time stamp.
If the time stamp in the database matches the time stamp in
the image the database is not needed (since the internal hash
tables already contain all of the information). When the database
is built the time stamp is saved in both the gcl image and the
database.

\subsection{compress.daase}
The compress database is special. It contains a list of symbols.
The character string name of a symbol in the other databases is
represented by a negative number. To get the real symbol back you
take the absolute value of the number and use it as a byte index
into the compress database. In this way long symbol names become
short negative numbers.

\subsubsection{interp.daase} 
\begin{verbatim}
 format of an entry in interp.daase:
  (constructor-name
    operationalist
    constructormodemap
    modemaps		 -- this should not be needed. eliminate it.
    object		 -- the name of the object file to load for this con.
    constructorcategory -- note that this info is the cadar of the
	  constructormodemap for domains and packages so it is stored
	  as NIL for them. it is valid for categories.
    niladic		 -- t or nil directly
    unused
    cosig		 -- kept directly
    constructorkind	 -- kept directly
    defaultdomain	 -- a short list, for %i
    ancestors		 -- used to compute new category updates
  )
\end{verbatim}

Here I'll try to outline the interp database write procedure

\begin{verbatim}
(defun write-interpdb ()
 "build interp.daase from hash tables"
 (declare (special $spadroot) (special *ancestors-hash*))
 (let (opalistpos modemapspos cmodemappos master masterpos obj *print-pretty*
	concategory categorypos kind niladic cosig abbrev defaultdomain
	ancestors ancestorspos out)
  (declare (special *print-pretty*))
  (print "building interp.daase")

; 1. We open the file we're going to create

  (setq out (open "interp.build" :direction :output))

; 2. We reserve some space at the top of the file for the key-time pair
;    We will overwrite these spaces just before we close the file.

  (princ "                              " out)

; 3. Make sure we write it out
  (finish-output out)

; 4. For every constructor in the system we write the parts:

  (dolist (constructor (|allConstructors|))
   (let (struct)

; 4a. Each constructor has a property list. A property list is a list
;     of (key . value) pairs. The property we want is called 'database
;     so there is a ('database . something) in the property list

    (setq struct (get constructor 'database))

; 5 We write the "operationsalist"
; 5a. We remember the current file position before we write
;     We need this information so we can seek to this position on read

    (setq opalistpos (file-position out))

; 5b. We get the "operationalist", compress it, and write it out

    (print (squeeze (database-operationalist struct)) out)

; 5c. We make sure it was written

    (finish-output out)

; 6 We write the "constructormodemap"
; 6a. We remember the current file position before we write

    (setq cmodemappos (file-position out))

; 6b. We get the "constructormodemap", compress it, and write it out

    (print (squeeze (database-constructormodemap struct)) out)

; 6c. We make sure it was written

    (finish-output out)

; 7. We write the "modemaps"
; 7a. We remember the current file position before we write

    (setq modemapspos (file-position out))

; 7b. We get the "modemaps", compress it, and write it out

    (print (squeeze (database-modemaps struct)) out)

; 7c. We make sure it was written

    (finish-output out)

; 8. We remember source file pathnames in the obj variable

    (if (consp (database-object struct)) ; if asharp code ...
     (setq obj
      (cons (pathname-name (car (database-object struct)))
            (cdr (database-object struct))))
     (setq obj
      (pathname-name
        (first (last (pathname-directory (database-object struct)))))))

; 9. We write the "constructorcategory", if it is a category, else nil
; 9a. Get the constructorcategory and compress it

    (setq concategory (squeeze (database-constructorcategory struct)))

; 9b. If we have any data we write it out, else we don't write it
;     Note that if there is no data then the byte index for the
;     constructorcatagory will not be a number but will be nil.

    (if concategory  ; if category then write data else write nil
     (progn
      (setq categorypos (file-position out))
      (print concategory out)
      (finish-output out))
     (setq categorypos nil))

; 10. We get a set of properties which are kept as "immediate" data
;     This means that the key table will hold this data directly
;     rather than as a byte index into the file.
; 10a. niladic data

    (setq niladic (database-niladic struct))

; 10b. abbreviation data (e.g. POLY for polynomial)

    (setq abbrev (database-abbreviation struct))

; 10c. cosig data

    (setq cosig (database-cosig struct))

; 10d. kind data

    (setq kind (database-constructorkind struct))

; 10e. defaultdomain data

    (setq defaultdomain (database-defaultdomain struct))

; 11. The ancestor data might exist. If it does we fetch it, 
;     compress it, and write it out. If it does not we place
;     and immediate value of nil in the key-value table

    (setq ancestors (squeeze (gethash constructor *ancestors-hash*))) ;cattable.boot
    (if ancestors
     (progn
      (setq ancestorspos (file-position out))
      (print ancestors out)
      (finish-output out))
     (setq ancestorspos nil))

; 12. "master" is an alist. Each element of the alist has the name of
;     the constructor and all of the above attributes. When the loop
;     finishes we will have constructed all of the data for the key-value
;     table

    (push (list constructor opalistpos cmodemappos modemapspos
      obj categorypos niladic abbrev cosig kind defaultdomain
      ancestorspos) master)))

; 13. The loop is done, we make sure all of the data is written

  (finish-output out)

; 14. We remember where the key-value table will be written in the file

  (setq masterpos (file-position out))

; 15. We compress and print the key-value table

  (print (mapcar #'squeeze master) out)

; 16. We make sure we write the table

  (finish-output out)

; 17. We go to the top of the file

  (file-position out 0)

; 18. We write out the (master-byte-position . universal-time) pair
;     Note that if the universal-time value matches the value of
;     *interp-stream-stamp* then there is no reason to read the
;     interp database because all of the data is already cached in
;     the image. This happens if you build a database and immediatly
;     save the image. The saved image already has the data since we
;     just wrote it out. If the *interp-stream-stamp* and the database
;     time stamp differ we "reread" the database on startup. Actually
;     we just open the database and fetch as needed. You can see fetches
;     by setting the *miss* variable non-nil.

  (print (cons masterpos (get-universal-time)) out)

; 19. We make sure we write it.

  (finish-output out)

; 20 And we are done

  (close out)))
\end{verbatim}

\subsubsection{browse.daase}
\begin{verbatim}
 format of an entry in browse.daase:
 ( constructorname
     sourcefile
     constructorform
     documentation
     attributes
     predicates
 )
\end{verbatim}
This is essentially the same overall process as above.

We reserve some space for the (key-table-byte-position . timestamp)

We loop across the list of constructors dumping the data and
remembering the byte positions in a key-value pair table.

We dump the final key-value pair table, write the byte position and
time stamp at the top of the file and close the file.
\begin{verbatim}
(defun write-browsedb ()
 "make browse.daase from hash tables"
 (declare (special $spadroot))
 (let (master masterpos src formpos docpos attpos predpos *print-pretty* out)
  (declare (special *print-pretty*))
  (print "building browse.daase")
  (setq out (open "browse.build" :direction :output))
  (princ "                              " out)
  (finish-output out)
  (dolist (constructor (|allConstructors|))
   (let (struct)
    (setq struct (get constructor 'database))
     ; sourcefile is small. store the string directly
    (setq src (database-sourcefile struct))
    (setq formpos (file-position out))
    (print (squeeze (database-constructorform struct)) out)
    (finish-output out)
    (setq docpos (file-position out))
    (print (database-documentation struct) out)
    (finish-output out)
    (setq attpos (file-position out))
    (print (squeeze (database-attributes struct)) out)
    (finish-output out)
    (setq predpos (file-position out))
    (print (squeeze (database-predicates struct)) out)
    (finish-output out)
    (push (list constructor src formpos docpos attpos predpos) master)))
  (finish-output out)
  (setq masterpos (file-position out))
  (print (mapcar #'squeeze master) out)
  (finish-output out)
  (file-position out 0)
  (print (cons masterpos (get-universal-time)) out)
  (finish-output out)
  (close out)))
\end{verbatim}

\subsubsection{category.daase}
This is a single table of category hash table information, dumped in the 
database format.
\begin{verbatim}
(defun write-categorydb ()
 "make category.daase from scratch. contains the *hasCategory-hash* table"
 (let (out master pos *print-pretty*)
  (declare (special *print-pretty*))
  (print "building category.daase")
  (|genCategoryTable|)
  (setq out (open "category.build" :direction :output))
  (princ "                              " out)
  (finish-output out)
  (maphash #'(lambda (key value)
    (if (or (null value) (eq value t))
     (setq pos value)
     (progn
      (setq pos (file-position out))
      (print (squeeze value) out)
      (finish-output out)))
     (push (list key pos) master))
     *hasCategory-hash*)
  (setq pos (file-position out))
  (print (mapcar #'squeeze master) out)
  (finish-output out)
  (file-position out 0)
  (print (cons pos (get-universal-time)) out)
  (finish-output out)
  (close out)))
\end{verbatim}

\subsection{operations.daase}
This is a single table of operations hash table information, dumped in the 
database format.
\begin{verbatim}
(defun write-operationdb ()
 (let (pos master out)
  (declare (special leaves))
  (setq out (open "operation.build" :direction :output))
  (princ "                              " out)
  (finish-output out)
  (maphash #'(lambda (key value)
   (setq pos (file-position out))
   (print (squeeze value) out)
   (finish-output out)
   (push (cons key pos) master))
   *operation-hash*)
  (finish-output out)
  (setq pos (file-position out))
  (print (mapcar #'squeeze master) out)
  (file-position out 0)
  (print (cons pos (get-universal-time)) out)
  (finish-output out)
  (close out)))
