annotate src/print.c @ 5772:cd4f5f1f1f4c
Add #'write-sequence, on the model of #'write-char, API from Common Lisp.
src/ChangeLog addition:
2013-12-17 Aidan Kehoe <kehoea@parhasard.net>
* lisp.h:
* lisp.h (PARSE_KEYWORDS_8):
Correct this in cases where we can have noticeably fewer arguments
than KEYWORDS_OFFSET, check whether nargs > pk_offset.
Declare check_sequence_range in this header.
* print.c:
* print.c (Fwrite_sequence) New:
Write a sequence to a stream, in the same way #'write-char and
#'terpri do. API from Common Lisp, not GNU, so while there is some
char-int confoundance, it's more limited than usual with GNU APIs.
* print.c (syms_of_print):
Make it available.
* sequence.c (check_sequence_range):
Export this to other files.
lisp/ChangeLog addition:
2013-12-17 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el:
* cl-extra.el (write-string): New.
* cl-extra.el (write-line): New.
Add these here, implemented in terms of #'write-sequence in print.c.
tests/ChangeLog addition:
2013-12-17 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Up max-lisp-eval-depth when compiling this file, some of what
we're doing in testing #'write-sequence is demanding.
* automated/lisp-tests.el (make-circular-list):
New argument VALUE, the car of the conses to create.
* automated/lisp-tests.el:
Test #'write-sequence, #'write-string, #'write-line with function,
buffer and marker STREAMs; test argument types, keyword argument
ranges and values.

| 628 However, if PRINTCHARFUN is a frame, printing of complex | |
| 629 structures becomes very expensive, because `append-message' | |
| 630 (called by echo_area_append) gets called as many times as | |
| 631 output_string() is called (and that's a *lot*). append-message | |
| 632 tries to keep top of the message-stack in sync with the contents | |
| 633 of " *Echo Area" buffer, consing a new string for each component | |
| 634 of the printed structure. For instance, if you print (a a), | |
| 635 append-message will cons up the following strings: | |

| 639 "(a " | |
| 640 "(a a" | |

| 643 and will use only the last one. With larger objects, this turns | |
| 644 into an O(n^2) consing frenzy that locks up XEmacs in incessant | |
| 645 garbage collection. | |
| 646 | |
| 647 We prevent this by creating a resizing_buffer stream and letting | |
| 648 the printer write into it. print_finish() will notice this | |
| 649 stream, and invoke echo_area_append() with the stream's buffer, | |
