Q: In C/C++ modes, I want:
Tabs as spaces Tabs is 4 spaces Persistent off auto formatting. Double-click selection across _ (underscore)
A: Try this in your .emacs:
(defun my-c-mode-common-hook () (setq tab-width 4) ;; don't treat _ as word delimiter (modify-syntax-entry ?_ "w") ;; this will make sure spaces are used instead of tabs (setq indent-tabs-mode t) ;; we don't like auto-newline and hungry-delete (c-toggle-auto-hungry-state -1) (c-toggle-auto-state -1) (setq c-basic-offset 4) ) (add-hook 'c-mode-common-hook 'my-c-mode-common-hook)
Q: How do I bind recompile to a key command
A: (define-key global-map [f7] 'recompile)
Q: How do I get tab to always insert 4 spaces in C++-mode?
Q: What is the command in C++-mode to move a region left or right as with command-[ ] in mac editors?
A: indent-rigidly is an interactive compiled Lisp function in `indent.el'. It is bound to C-x TAB. (indent-rigidly start end arg)
Indent all lines starting in the region sideways by arg columns. Called from a program, takes three arguments, start, end and arg. You can remove all indentation from a region by giving a large negative arg.
Q: Get bjam to compile / force execute
