view lisp/cus-load.el @ 5914:bd4d2c8ef9cc
Use the existing C-level line number cache within #'line-number.
src/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* buffer.c:
* buffer.c (Fline_number): New C implementation, using the line
number cache of line-number.c, with a new optional BUFFER
argument.
* buffer.c (syms_of_buffer):
Make it available to Lisp.
* line-number.c (buffer_line_number):
New argument, RESPECT-NARROWING, describing whether to count from
the beginning of the visible region or from the beginning of the
buffer.
* line-number.h:
* line-number.h (buffer_line_number): Update its declaration.
* redisplay.c (window_line_number): Call it with the new argument.
lisp/ChangeLog addition:
2015-05-15 Aidan Kehoe <kehoea@parhasard.net>
* simple.el:
* simple.el (line-number): Moved to buffer.c; we have an existing
line number cache in C, it's a shame not to have it available.
