[I first sent this to gdb-bug at gnu dot org, then noticed this mailing list, hope, it's the right place to send this, this time] Being a vi user, I've long tried to interface it with GDB. I had written once a kind of wrapper that opened two pseudo-ttys, catched the \032\032 sequences sent by "gdb -f" and turned them into ":e +line filename" sent to vi. I recently noticed I could use GNU screen to do this. screen provides a special control sequence which allows to run arbitrary screen commands based on output from a command. >From "info -f screen -n 'Control Sequences'": I| ESC ] 83 ; cmd ^G (A) Execute screen command. This only works if I| multi-user support is compiled into screen. I| The pseudo-user ":window:" is used to check I| the access control list. Use "addacl :window: I| -rwx #?" to create a user with no rights and I| allow only the needed commands. My idea was then, that gdb could send something like "\e]83;<a screen command to have vi open the right file at the right line>\a" instead of sending "\032\032filename:line:char:mid:addr\n". That's my suggestion: add a new -F/--annotation-format option to GDB with one required argument only used when the annotation_level is 1 (-f option). The default would be: "\032\032%f:%l:%c:%m:%a\n". Attached, you'll find a quick patch on GDB 5.3, with my suggestion implemented. (%f, %l, %c, %m, %a are replaced by filename, line#, char#, middle/beg, address in the annotation format). vim-gdb-screen is a GNU bash script that sets up a screen environment with a splitted screen (vim above, gdb below) to use this feature. This must be run from within screen, with two optionnal arguments: the executable to debug and its source directory. screenshot.png is a screenshot of an example usage. Tell me what you think of it and don't hesitate to ask more details. Best regards, Stéphane
