This supercedes the last one. I didn't have time this morning to reorganize the C code and write a lisp-level interface for gpm-minor-mode to make it more flexible, but you can now paste from other linux consoles into XEmacs. It's kind of a hack, since the paste code in the linux kernel writes directly to the console. If anyone can think of a better way to do it, please let me know. This is what I do right now: 1) Hook up a filedesc_input_stream to DEVICE_INFD() of the device. 2) Make the filedescriptor non-blocking. I really hate doing this, but there was no other way (that I could find) to make Lstream_read() correctly bail out after reading all the ioctl-inspired data. 3) call { char c = 3; ioctl(fd, TIOCLINUX, &c); } - this actually copies the pasted data into the virtual console's input buffer. 4) Read from the lstream until we stop getting data (<= 0 bytes read), and write the data to a resizing_buffer_stream. 5) flush the buffer stream and make a string out of it 6) kill the streams The reason I dislike #2 so much is that there is no set_descriptor_blocking() function call, but in my testing under linux, it has not proved fatal to leave the descriptor in non-blocking mode. There was also a patch needed to mouse.el - it would just call (yank) if you were not on a window system. I don't know how many other areas like this there are lying around. Unfortunately, I can't see an easy way to make the 'own_selection' method work with the ioctl's that linux provides right now. The ioctl requires the starting and ending positions on screen that you want to copy to the cut buffer, which is nothing like the current XEmacs selection model. With this latest patch, I can cut & paste from a virtual console to XEmacs, and can also select & paste from within emacs. The selection is a little weird, since you don't see the highlighting while the mouse is dragging, but the old GPM code behaved in the same way. The mouse-cursur flickering is still there as well. Anybody have a clue on how to make this better? I could provide a lisp-function to call GPM_DRAWPOINTER and push a magic eval even somewhere, but that seems kind of icky, and I don't think there are any ways to do this type of event mucking outside of event-Xt.c or event-unixoid.c - everything in there is static. I'm not sending this to xemacs-patches until a few more people can try it out. I'd love to get the flicker problem fixed sometime tonight, so if anybody has any ideas, lemme know. -Bill P.
