;;; List Callers: A Static Analysis Cross Referencing Tool for Lisp 
;;; ****************************************************************
;;; 
;;; The List Callers system is a portable Common Lisp cross referencing
;;; utility. It grovels over a set of files and compiles a database of the
;;; locations of all references for each symbol used in the files.
;;; List Callers is similar to the Symbolics Who-Calls and the
;;; Xerox Masterscope facilities.
;;;
;;; When you change a function or variable definition, it can be useful
;;; to know its callers, in order to update each of them to the new
;;; definition. Similarly, having a graphic display of the structure 
;;; (e.g., call graph) of a program can help make undocumented code more
;;; understandable. This static code analyzer facilitates both capabilities.
;;; The database compiled by xref is suitable for viewing by a graphical 
;;; browser. (Note: the reference graph is not necessarily a DAG. Since many
;;; graphical browsers assume a DAG, this will lead to infinite loops.
;;; Some code which is useful in working around this problem is included,
;;; as well as a sample text-indenting outliner and an interface to Bates'
;;; PSGraph Postscript Graphing facility.)

;;; Change Log *********************
;;; ********************************
;;;
;;; 27-FEB-91 mk   Added insert arg to psgraph-xref to allow the postscript
;;;                graphs to be inserted in Scribe documents.
;;; 21-FEB-91 mk   Added warning if not compiled.
;;; 07-FEB-91 mk   Fixed bug in record-callers with regard to forms at 
;;;                toplevel.
;;; 21-JAN-91 mk   Added file xref-test.lisp to test xref.
;;; 16-JAN-91 mk   Added definition WHO-CALLS to parallel the Symbolics syntax.
;;; 16-JAN-91 mk   Added macroexpansion capability to record-callers. Also
;;;                added parameter *handle-macro-forms*, defaulting to T.
;;; 16-JAN-91 mk   Modified print-caller-tree and related functions
;;;                to allow the user to specify root nodes. If the user
;;;                doesn't specify them, it will default to all root
;;;                nodes, as before. 
;;; 16-JAN-91 mk   Added parameter *default-graphing-mode* to specify
;;;                the direction of the graphing. Either :call-graph,
;;;                where the children of a node are those functions called
;;;                by the node, or :caller-graph where the children of a
;;;                node are the callers of the node. :call-graph is the
;;;                default.
;;; 16-JAN-91 mk   Added parameter *indent-amount* to control the indentation
;;;                in print-indented-tree.
;;; 16-JUL-90 mk   Functions with argument lists of () were being ignored
;;;                because of a (when form) wrapped around the body of
;;;                record-callers. Then intent of (when form) was as an extra
;;;                safeguard against infinite looping. This wasn't really
;;;                necessary, so it has been removed.
;;; 16-JUL-90 mk   PSGraph-XREF now has keyword arguments, instead of
;;;                optionals.
;;; 16-JUL-90 mk   Added PRINT-CLASS-HIERARCHY to use psgraph to graph the
;;;                CLOS class hierarchy. This really doesn't belong here,
;;;                and should be moved to psgraph.lisp as an example of how
;;;                to use psgraph.
;;; 16-JUL-90 mk   Fixed several caller patterns. The pattern for member
;;;                had an error which caused many references to be missed.
;;; 16-JUL-90 mk   Added ability to save/load processed databases.
;;;  5-JUL-91 mk    Fixed warning of needing compilation to occur only when the
;;;                 source is loaded.
;;; 20-SEP-93 mk    Added fix from Peter Norvig to allow Xref to xref itself.
;;;                 The arg to macro-function must be a symbol.
;;;  7-APR-12 heller  Break lines at 80 columns.

;;; ********************************
;;; To Do **************************
;;; ********************************
;;;
;;; Verify that:
;;;    o  null forms don't cause it to infinite loop.
;;;    o  nil matches against null argument lists.
;;;    o  declarations and doc are being ignored.
;;;
;;; Would be nice if in addition to showing callers of a function, it
;;; displayed the context of the calls to the function (e.g., the
;;; immediately surrounding form). This entails storing entries of
;;; the form (symbol context*) in the database and augmenting
;;; record-callers to keep the context around. The only drawbacks is
;;; that it would cons a fair bit. If we do this, we should store
;;; additional information as well in the database, such as the caller
;;; pattern type (e.g., variable vs. function).
;;;
;;; Write a translator from BNF (at least as much of BNF as is used
;;; in CLtL2), to the format used here.
;;;
;;; Should automatically add new patterns for new functions and macros
;;; based on their arglists. Probably requires much more than this
;;; simple code walker, so there isn't much we can do.
;;;
;;; Defmacro is a problem, because it often hides internal function
;;; calls within backquote and quote, which we normally ignore. If
;;; we redefine QUOTE's pattern so that it treats the arg like a FORM,
;;; we'll probably get them (though maybe the syntax will be mangled),
;;; but most likely a lot of spurious things as well. 
;;;
;;; Define an operation for Defsystem which will run XREF-FILE on the
;;; files of the system. Or yet simpler, when XREF sees a LOAD form
;;; for which the argument is a string, tries to recursively call
;;; XREF-FILE on the specified file. Then one could just XREF-FILE
;;; the file which loads the system. (This should be a program
;;; parameter.)
;;;
;;; Have special keywords which the user may place in a file to have
;;; XREF-FILE ignore a region.
;;;
;;; Should we distinguish flet and labels from defun? I.e., note that
;;; flet's definitions are locally defined, instead of just lumping
;;; them in with regular definitions.
;;;
;;; Add patterns for series, loop macro.
;;;
;;; Need to integrate the variable reference database with the other
;;; databases, yet maintain separation. So we can distinguish all
;;; the different types of variable and function references, without
;;; multiplying databases.
;;;
;;; Would pay to comment record-callers and record-callers* in more
;;; depth.

;;; ****************************************************************
;;;
;;; XREF analyzes a user's program, determining which functions call a
;;; given function, and the location of where variables are bound/assigned
;;; and used. The user may retrieve this information for either a single
;;; symbol, or display the call graph of portions of the program
;;; (including the entire program). This allows the programmer to debug
;;; and document the program's structure.
;;; 
;;; XREF is primarily intended for analyzing large programs, where it is
;;; difficult, if not impossible, for the programmer to grasp the structure
;;; of the whole program. Nothing precludes using XREF for smaller programs,
;;; where it can be useful for inspecting the relationships between pieces
;;; of the program and for documenting the program.
;;; 
;;; Two aspects of the Lisp programming language greatly simplify the
;;; analysis of Lisp programs:
;;; 	o  Lisp programs are naturally represented as data.
;;; 	   Successive definitions from a file are easily read in
;;; 	   as list structure.
;;; 	o  The basic syntax of Lisp is uniform. A list program
;;; 	   consists of a set of nested forms, where each form is
;;; 	   a list whose car is a tag (e.g., function name) that
;;; 	   specifies the structure of the rest of the form.
;;; Thus Lisp programs, when represented as data, can be considered to be
;;; parse trees. Given a grammar of syntax patterns for the language, XREF
;;; recursively descends the parse tree for a given definition, computing
;;; a set of relations that hold for the definition at each node in the
;;; tree. For example, one kind of relation is that the function defined
;;; by the definition calls the functions in its body. The relations are
;;; stored in a database for later examination by the user.
;;; 
;;; While XREF currently only works for programs written in Lisp, it could
;;; be extended to other programming languages by writing a function to
;;; generate parse trees for definitions in that language, and a core
;;; set of patterns for the language's syntax.
;;; 
;;; Since XREF normally does a static syntactic analysis of the program, 
;;; it does not detect references due to the expansion of a macro definition. 
;;; To do this in full generality XREF would have to have knowledge about the
;;; semantics of the program (e.g., macros which call other functions to
;;; do the expansion). This entails either modifying the compiler to
;;; record the relationships (e.g., Symbolics Who-Calls Database) or doing
;;; a walk of loaded code and macroexpanding as needed (PCL code walker).
;;; The former is not portable, while the latter requires that the code
;;; used by macros be loaded and in working order. On the other hand, then
;;; we would need no special knowledge about macros (excluding the 24 special
;;; forms of Lisp).
;;;
;;; Parameters may be set to enable macro expansion in XREF. Then XREF
;;; will expand any macros for which it does not have predefined patterns.
;;; (For example, most Lisps will implement dolist as a macro. Since XREF
;;; has a pattern defined for dolist, it will not call macroexpand-1 on
;;; a form whose car is dolist.) For this to work properly, the code must
;;; be loaded before being processed by XREF, and XREF's parameters should
;;; be set so that it processes forms in their proper packages. 
;;;
;;; If macro expansion is disabled, the default rules for handling macro
;;; references may not be sufficient for some user-defined macros, because
;;; macros allow a variety of non-standard syntactic extensions to the
;;; language. In this case, the user may specify additional templates in
;;; a manner similar to that in which the core Lisp grammar was specified.

;;; The following functions are called to cross reference the source files.
;;;
;;; XREF-FILES (&rest files)                                      [FUNCTION]
;;;    Grovels over the lisp code located in source file FILES, using
;;;    xref-file.
;;;
;;; XREF-FILE (filename &optional clear-tables verbose)       [Function]
;;;    Cross references the function and variable calls in FILENAME by
;;;    walking over the source code located in the file. Defaults type of
;;;    filename to ".lisp". Chomps on the code using record-callers and
;;;    record-callers*. If CLEAR-TABLES is T (the default), it clears the
;;;    callers database before processing the file. Specify CLEAR-TABLES as
;;;    nil to append to the database. If VERBOSE is T (the default), prints
;;;    out the name of the file, one progress dot for each form processed,

;;;
;;; -----
;;; The following functions display information about the uses of the

;;;
;;; LIST-READERS (symbol)                                         [FUNCTION]

;;;
;;; WHO-CALLS (symbol &optional how)                              [FUNCTION]
;;;    Lists callers of symbol. HOW may be :function, :reader, :setter,
;;;    or :variable."
;;;
;;; WHAT-FILES-CALL (symbol)                                      [FUNCTION]

;;;
;;; -----
;;; The following functions may be useful for viewing the database and
;;; debugging the calling patterns.
;;;
;;; *LAST-FORM* ()                                                [VARIABLE]
;;;    The last form read from the file. Useful for figuring out what went
;;;    wrong when xref-file drops into the debugger.
;;;
;;; *XREF-VERBOSE* t                                              [VARIABLE]
;;;    When T, xref-file(s) prints out the names of the files it looks at,
;;;    progress dots, and the number of forms read.
;;;
;;; *TYPES-TO-IGNORE* (quote (:lisp :lisp2))                      [VARIABLE]
;;;    Default set of caller types (as specified in the patterns) to ignore
;;;    in the database handling functions. :lisp is CLtL 1st edition,
;;;    :lisp2 is additional patterns from CLtL 2nd edition.
;;;
;;; *HANDLE-PACKAGE-FORMS* ()                                     [VARIABLE]
;;;    When non-NIL, and XREF-FILE sees a package-setting form like
;;;    IN-PACKAGE, sets the current package to the specified package by
;;;    evaluating the form. When done with the file, xref-file resets the
;;;    package to its original value. In some of the displaying functions,
;;;    when this variable is non-NIL one may specify that all symbols from a
;;;    particular set of packages be ignored. This is only useful if the
;;;    files use different packages with conflicting names.
;;;
;;; *HANDLE-FUNCTION-FORMS* t                                     [VARIABLE]
;;;    When T, XREF-FILE tries to be smart about forms which occur in
;;;    a function position, such as lambdas and arbitrary Lisp forms.
;;;    If so, it recursively calls record-callers with pattern 'FORM.
;;;    If the form is a lambda, makes the caller a caller of
;;;    :unnamed-lambda.
;;;
;;; *HANDLE-MACRO-FORMS* t                                        [VARIABLE]
;;;    When T, if the file was loaded before being processed by XREF, and
;;;    the car of a form is a macro, it notes that the parent calls the
;;;    macro, and then calls macroexpand-1 on the form.
;;;
;;; *DEFAULT-GRAPHING-MODE* :call-graph                           [VARIABLE]
;;;    Specifies whether we graph up or down. If :call-graph, the children
;;;    of a node are the functions it calls. If :caller-graph, the
;;;    children of a node are the functions that call it.
;;;
;;; *INDENT-AMOUNT* 3                                             [VARIABLE]
;;;    Number of spaces to indent successive levels in PRINT-INDENTED-TREE.
;;;
;;; DISPLAY-DATABASE (&optional database types-to-ignore)         [FUNCTION]
;;;    Prints out the name of each symbol and all its callers. Specify
;;;    database :callers (the default) to get function call references,
;;;    :file to the get files in which the symbol is called, :readers to get
;;;    variable references, and :setters to get variable binding and
;;;    assignments. Ignores functions of types listed in types-to-ignore.
;;;
;;; PRINT-CALLER-TREES (&key (mode *default-graphing-mode*)       [FUNCTION]
;;;                     (types-to-ignore *types-to-ignore*)
;;;                     compact root-nodes)
;;;    Prints the calling trees (which may actually be a full graph and not
;;;    necessarily a DAG) as indented text trees using
;;;    PRINT-INDENTED-TREE. MODE is :call-graph for trees where the children
;;;    of a node are the functions called by the node, or :caller-graph for
;;;    trees where the children of a node are the functions the node calls.
;;;    TYPES-TO-IGNORE is a list of funcall types (as specified in the
;;;    patterns) to ignore in printing out the database. For example,
;;;    '(:lisp) would ignore all calls to common lisp functions. COMPACT is
;;;    a flag to tell the program to try to compact the trees a bit by not
;;;    printing trees if they have already been seen. ROOT-NODES is a list
;;;    of root nodes of trees to display. If ROOT-NODES is nil, tries to
;;;    find all root nodes in the database.
;;;
;;; MAKE-CALLER-TREE (&optional (mode *default-graphing-mode*)    [FUNCTION]
;;;                   (types-to-ignore *types-to-ignore*)
;;;                   compact)
;;;    Outputs list structure of a tree which roughly represents the
;;;    possibly cyclical structure of the caller database.
;;;    If mode is :call-graph, the children of a node are the functions
;;;    it calls. If mode is :caller-graph, the children of a node are the
;;;    functions that call it.
;;;    If compact is T, tries to eliminate the already-seen nodes, so
;;;    that the graph for a node is printed at most once. Otherwise it will
;;;    duplicate the node's tree (except for cycles). This is usefull
;;;    because the call tree is actually a directed graph, so we can either
;;;    duplicate references or display only the first one.
;;;
;;; DETERMINE-FILE-DEPENDENCIES (&optional database)          [FUNCTION]
;;;    Makes a hash table of file dependencies for the references listed in
;;;    DATABASE. This function may be useful for automatically resolving
;;;    file references for automatic creation of a system definition
;;;    (defsystem).
;;;
;;; PRINT-FILE-DEPENDENCIES (&optional database)              [FUNCTION]
;;;    Prints a list of file dependencies for the references listed in
;;;    DATABASE. This function may be useful for automatically computing
;;;    file loading constraints for a system definition tool.
;;;
;;; WRITE-CALLERS-DATABASE-TO-FILE (filename)                     [FUNCTION]
;;;    Saves the contents of the current callers database to a file. This
;;;    file can be loaded to restore the previous contents of the
;;;    database. (For large systems it can take a long time to crunch
;;;    through the code, so this can save some time.)
;;;
;;; -----
;;; The following macros define new function and macro call patterns.
;;; They may be used to extend the static analysis tool to handle
;;; new def forms, extensions to Common Lisp, and program defs.
;;;
;;; DEFINE-PATTERN-SUBSTITUTION (name pattern)                    [MACRO]
;;;    Defines NAME to be equivalent to the specified pattern. Useful for
;;;    making patterns more readable. For example, the LAMBDA-LIST is
;;;    defined as a pattern substitution, making the definition of the
;;;    DEFUN caller-pattern simpler.
;;;
;;; DEFINE-CALLER-PATTERN (name pattern &optional caller-type)    [MACRO]
;;;    Defines NAME as a function/macro call with argument structure
;;;    described by PATTERN. CALLER-TYPE, if specified, assigns a type to
;;;    the pattern, which may be used to exclude references to NAME while
;;;    viewing the database. For example, all the Common Lisp definitions
;;;    have a caller-type of :lisp or :lisp2, so that you can exclude
;;;    references to common lisp functions from the calling tree.
;;;
;;; DEFINE-VARIABLE-PATTERN (name &optional caller-type)          [MACRO]
;;;    Defines NAME as a variable reference of type CALLER-TYPE. This is
;;;    mainly used to establish the caller-type of the variable.
;;;
;;; DEFINE-CALLER-PATTERN-SYNONYMS (source destinations)          [MACRO]
;;;    For defining function caller pattern syntax synonyms. For each name
;;;    in DESTINATIONS, defines its pattern as a copy of the definition
;;;    of SOURCE. Allows a large number of identical patterns to be defined
;;;    simultaneously. Must occur after the SOURCE has been defined.
;;;
;;; -----
;;; This system includes pattern definitions for the latest
;;; common lisp specification, as published in Guy Steele,
;;; Common Lisp: The Language, 2nd Edition.
;;;
;;; Patterns may be either structures to match, or a predicate
;;; like symbolp/numberp/stringp. The pattern specification language
;;; is similar to the notation used in CLtL2, but in a more lisp-like 
;;; form:
;;;    (:eq name)           The form element must be eq to the symbol NAME.
;;;    (:test test)         TEST must be true when applied to the form element.
;;;    (:typep type)        The form element must be of type TYPE.
;;;    (:or pat1 pat2 ...)  Tries each of the patterns in left-to-right order,
;;;                         until one succeeds.
;;;                         Equivalent to { pat1 | pat2 | ... }
;;;    (:rest pattern)      The remaining form elements are grouped into a
;;;                         list which is matched against PATTERN.
;;;    (:optional pat1 ...) The patterns may optionally match against the
;;;                         form element.
;;;                         Equivalent to [ pat1 ... ].
;;;    (:star pat1 ...)     The patterns may match against the patterns
;;;                         any number of times, including 0.
;;;                         Equivalent to { pat1 ... }*.
;;;    (:plus pat1 ...)     The patterns may match against the patterns
;;;                         any number of times, but at least once.
;;;                         Equivalent to { pat1 ... }+.
;;;    &optional, &key,     Similar in behavior to the corresponding
;;;    &rest                lambda-list keywords.
;;;    FORM                 A random lisp form. If a cons, assumes the
;;;                         car is a function or macro and tries to
;;;                         match the args against that symbol's pattern.
;;;                         If a symbol, assumes it's a variable reference.
;;;    :ignore              Ignores the corresponding form element.
;;;    NAME                 The corresponding form element should be
;;;                         the name of a new definition (e.g., the
;;;                         first arg in a defun pattern is NAME.
;;;    FUNCTION, MACRO      The corresponding form element should be
;;;                         a function reference not handled by FORM.
;;;                         Used in the definition of apply and funcall.
;;;    VAR                  The corresponding form element should be
;;;                         a variable definition or mutation. Used
;;;                         in the definition of let, let*, etc.
;;;    VARIABLE             The corresponding form element should be
;;;                         a variable reference. 
;;;
;;; In all other pattern symbols, it looks up the symbols pattern substitution
;;; and recursively matches against the pattern. Automatically destructures
;;; list structure that does not include consing dots.
;;;
;;; Among the pattern substitution names defined are:
;;;    STRING, SYMBOL, NUMBER    Appropriate :test patterns.
;;;    LAMBDA-LIST               Matches against a lambda list.
;;;    BODY                      Matches against a function body definition.
;;;    FN                        Matches against #'function, 'function,
;;;                              and lambdas. This is used in the definition
;;;                              of apply, funcall, and the mapping patterns.
;;;    and others...
;;;
;;; Here's some sample pattern definitions:
;;; (define-caller-pattern defun 
;;;   (name lambda-list
;;;	(:star (:or documentation-string declaration))
;;;	(:star form))
;;;  :lisp)
;;; (define-caller-pattern funcall (fn (:star form)) :lisp)
;;;
;;; In general, the system is intelligent enough to handle any sort of
;;; simple funcall. One only need specify the syntax for functions and
;;; macros which use optional arguments, keyword arguments, or some
;;; argument positions are special, such as in apply and funcall, or
;;; to indicate that the function is of the specified caller type.
;;;
;;;
;;; NOTES:
;;;
;;;    XRef assumes syntactically correct lisp code.
;;;
;;;    This is by no means perfect. For example, let and let* are treated
;;;    identically, instead of differentiating between serial and parallel
;;;    binding. But it's still a useful tool. It can be helpful in 
;;;    maintaining code, debugging problems with patch files, determining
;;;    whether functions are multiply defined, and help you remember where
;;;    a function is defined or called.
;;;
;;;    XREF runs best when compiled.
