Storm @ 2004-03-03 14:39 UTC (permalink / raw) [This is extracted from my response to Nick Roberts re. supporting GDB overlay arrows at C and assembler levels simultaneiously. It hit the emacs-devel bit-bucket on Mar 02. ++kfs] I have just installed changed to properly support multiple overlay arrows. [Some packages attempts to do this by making overlay-arrow-position buffer local, but that doesn't really work well with the redisplay code, as it may fail to notice changes to an overlay arrow in some cases.] To create an additional overlay arrow, create a new variable similar to overlay-arrow-position, e.g. gdb-asm-overlay-arrow-position and add it to the new variable overlay-arrow-variable-list; like this: (push 'gdb-asm-overlay-arrow-position overlay-arrow-variable-list) Then you can use gdb-asm-overlay-arrow-position just like the overlay-arrow-position variable. If you want to use a different fringe bitmap for the asm bitmap, you can set it with (require 'fringe) (put 'gdb-asm-overlay-arrow-position 'overlay-arrow-bitmap right-truncation-fringe-bitmap) ; the -> arrow -- Kim F.

I've committed this change which seems to work fine on a graphical display but not on a text-only terminal. Roughly, I've taken code from gud-display-line and put it in gdb-assembler-custom. In this manner, I've created a variable called gdb-overlay-arrow-string (set to "=>") but this doesn't have the meaning given to overlay-arrow-string. On a related note, I see that the overlay arrow is only represented as a string on a text-only terminal. It seems to me that, now fringes can be toggled, this should be extended to graphical displays where there is no left-hand fringe. Nick ^ permalink raw reply [flat|nested] 5+ messages in thread

Btw, why doesn't gdb-ui.el live in progmodes, together with gud.el? ^ permalink raw reply [flat|nested] 5+ messages in thread

It did live together with gud.el before it was moved. Also, XEmacs has a directory called debug but, as a previous thread observed, CVS doesn't handle moves very well. I note the subversion has been released now, which might be worth bearing in mind for the future. For the present, however, I agree that gdb-ui.el should be moved to progmodes.
