M-x rope-generate-autoimport-cache is necessary if I want to autoimport a freshly defined name (with M-x rope-auto-import), but it takes ~60 seconds for my project and happens in the foreground, so I can't use emacs while it's running.
Is there a way to generate the autoimport cache periodically in the background?

In either spark-shell, or scala repl, when I pop out (via control-Z) to do a shell command I find that auto-complete no longer works when i come back to the REPL (in linux i would type 'fg' to bring the paused program in to the foreground).
i have tried 'reset' (to reset terminal settings) before hitting 'fg' to bring the REPL back. That did not help.
The work around is just to restart the REPL or use another window, but this is annoying if screen real estate is limited, and also when the REPL takes a while to initialize. Anyone know of a good trick to make this work ? Thanks!
(Emacs newbie here)
Sometimes a Help buffer gets opened in my emacs editor. It opens in a different pane, splitting the current window into two halves vertically.
When I use C-k buffer-name, to kill a buffer (say Help), some other buffer (say scratch) gets opened automatically in that pane.
Is it possible to revert to my previous configuration, after a random buffer (Help or Debug..) gets opened.
My previous configuration would be to go back to a single window with no panes
To revert to the previous window configuration after any arbitrary change(s), you should enable winner-mode in your .emacs file:
(winner-mode 1)
Then you can use C-c<left> (repeatedly, if necessary) to undo window configuration changes with winner-undo.
C-c<right> calls winner-redo which returns you to the most recent configuration (immediately; not in single steps the like the 'undo' command).
Winner mode is the key to never ever getting annoyed by Emacs creating an unwanted window, but it also lets you do things you wouldn't have done before (for instance C-x1 to maximise one of your windows temporarily for easier reading, because getting back all the windows you just deleted is now trivial).
Obviously this is also incredibly useful if you accidentally mess up your window config!
Hello to revert back to one buffer you must hit C-x1 while standing in the buffer you want to keep. And to switch between frames C-xo
I have two windows open in my Emacs session. Both are remote files opened using tramp. I make a change in window A and switch to window B without saving file in window A. When Emacs decides to autosave, the buffer displayed in window B is switched to the buffer from window A that was autosaved. This only happens when using tramp, not local files.
Another thing I have noticed is, that if I have the same file opened in two windows, because I need to reference something at another position in the file and save the file, the buffer I'm in sometimes jumps to the position that the point is in the other window, so I have to move around to get back to the place where I was editing.
Is this a bug or is there some setting that I have(n't) set? I suspect it is something related to refreshing the windows when saving.
i'm using Emacs 24.3 on OSX, but I have seen this using Linux too.
Sounds very much like a bug, to me. Can you reproduce this starting from emacs -Q (i.e., with no init file)?
If so, use M-x report-emacs-bug to give Emacs Dev the recipe. If not, bisect your init file recursively until you locate the culprit code. Then ask for more help here, if it's not clear how to fix the problem.
I learned that to add those codes in .emacs can make Emacs saves automatically all situations before quitting and start it next time, Emacs can show the last situation and go on editing it.
(load "desktop")
(desktop-load-default)
(desktop-read)
(add-hook 'kill-emacs-hook
'(lambda()(desktop-save "~/")))
but this codes makes a problem that you only can open one Emacs, when you want to start another Emacs at the same time, only the previous one can run.
I want the function saving all situations for the next use, but I also need to start one more Emacs, How can I get the two sides work simultaneously?
Thank you for your help. I am waiting......
Use different desktop files; or use emacsclient instead of emacs to start new editing buffers once you have your main Emacs up and running. There are multiple examples in Google of an emacs alias / function / whatever to start Emacs if it is not running, and otherwise run emacsclient.
I have just installed cedet (CVS version) and I am now playing with in emacs and my C++ source code.
Regarding the auto complete, I can invoke the tool tip and the menu from their semantic-ia-complete-* commands.
Does anyone know how I can make the auto complete tip appear automatically without my having to invoke a command (semantic-ia-complete-tip)? Is this even possible?
From CEDET website:
Automatically starting inline completion in idle time
M-x global-semantic-idle-completions-mode
This is a minor mode which runs
semantic-complete-analyze-inline-idle
during idle time. Instead of trying to
complete the symbol immediately, it
will just display the possible
completions, and underline the current
symbol the cursor is on.
In practice this means that the possible completions will appear whenever you stop typing and the cursor is under a symbol where completions are possible.
To use it, just put
(global-semantic-idle-completions-mode)
to your .emacs after loading the CEDET.
