;; CCL commit r11373 | gz | 2008-11-16 16:35:28 +0100 (Sun, 16 Nov 2008)
|
|
;; contains some interesting details:
|
|
;;
|
|
;; Source location are recorded in CCL:SOURCE-NOTE's, which are objects
|
|
;; with accessors CCL:SOURCE-NOTE-FILENAME, CCL:SOURCE-NOTE-START-POS,
|
|
;; CCL:SOURCE-NOTE-END-POS and CCL:SOURCE-NOTE-TEXT. The start and end
|
|
;; positions are file positions (not character positions). The text will
|
|
;; be NIL unless text recording was on at read-time. If the original
|
|
;; file is still available, you can force missing source text to be read
|
|
;; from the file at runtime via CCL:ENSURE-SOURCE-NOTE-TEXT.
|
|
;;
|
|
;; Source-note's are associated with definitions (via record-source-file)
|
|
;; and also stored in function objects (including anonymous and nested
|
|
;; functions). The former can be retrieved via
|
|
;; CCL:FIND-DEFINITION-SOURCES, the latter via CCL:FUNCTION-SOURCE-NOTE.
|
|
;;
|
|
;; The recording behavior is controlled by the new variable
|
|
;; CCL:*SAVE-SOURCE-LOCATIONS*:
|
|
;;
|
|
;; If NIL, don't store source-notes in function objects, and store only
|
|
;; the filename for definitions (the latter only if
|
|
;; *record-source-file* is true).
|
|
;;
|
|
;; If T, store source-notes, including a copy of the original source
|
|
;; text, for function objects and definitions (the latter only if
|
|
;; *record-source-file* is true).
|
|
;;
|
|
;; If :NO-TEXT, store source-notes, but without saved text, for
|
|
;; function objects and defintions (the latter only if
|
|
;; *record-source-file* is true). This is the default.
|
|
;;
|
|
;; PC to source mapping is controlled by the new variable
