I've recently declared emacs bankruptcy and in rebuilding my config switched from the old python-mode.el to the built-in python.el.
One thing that's I'm missing is the old behaviour of auto-indenting to the correct level when hitting RET. Is there any way to re-enable this?
In upcoming Emacs 24.4 auto-indendation is enabled by default thanks to electric-indent-mode. Since Emacs 24.4 has been in feature-freeze for quite some time now, there should be no major breaking bugs left, so you could already make a switch.
Try this:
(add-hook 'python-mode-hook 'my-python-hook)
(defun my-python-hook ()
(define-key python-mode-map (kbd "RET") 'newline-and-indent))

Emacs 24.5, turn on CUA mode.
My binding:
(global-set-key (kbd "M-x") 'helm-M-x)
I want paste(yank) by C-v in minibuffer in 2 cases:
M-x and then paste(C-v) some text
I-search (C-f) and then paste(C-v) some text
Is this a possible in CUA mode?
I found a solution from: http://tahirhassan.blogspot.kr/2014/01/emacs-cua-mode-and-isearch.html
(define-key isearch-mode-map (kbd "C-v") 'isearch-yank-kill)
It works for me.
M-x C-v works fine, with emacs -Q (no init file).
C-s C-v does not - it seems that cua-mode does not affect Isearch - just use C-y instead of C-v. If you want a change in that regard (i.e., an improvement for cua-mode with Isearch), consider filing an Emacs enhancement request: M-x report-emacs-bug.
If the problem is introduced by using Helm (which it seems to be), consider filing a Helm bug report or asking Helm support. (But maybe someone here can tell you how to handle that.)
I want to get the search at point functionality ("*" and "#") in emacs.
So I want to use "*" and "#" from the emacs evil-mode, as this is one of the suggestions. However, I don't want anything else from the evil-mode, just those two functions!
This is my .emacs file:
(package-initialize)
(evil-mode 1) ;; enable evil-mode
(global-set-key (kbd "C-*") 'evil-search-symbol-forward)
(global-set-key (kbd "C-#") 'evil-search-symbol-backward)
Now the keybindings work, but I loaded the whole evil-mode, so it messes up my standard emacs keybindings like "C-y" for yank.
If I don't load the evil-mode in the .emacs file, I get the error:
Symbol's function definition is void: evil-search-symbol-forward
#event_jr's answer mentions highlight-symbols, which is probably a much more lightweight way to do what you want.
However, if you really want to use the evil version, you can (require 'evil) in your .emacs file without turning it on (ie, leave off the (evil-mode 1) statement).
Meanwhile, the functions you want are actually named evil-search-word-forward and evil-search-word-backward, not the ...-symbol-... version you saw on the wiki page (which is probably outdated).
You should use highlight-symbols for symbol jumping and highlighting.
I installed SML Mode in Emacs and the indentation is messed up. I disabled all my .emacs customizations, but that didn't make any difference. At the end of each line in the code below, I used C-j, which is mapped to newline-and-indent.
If I highlight everything and reindent (C-M-\), the result makes more sense:
I'm using Emacs 24.1.1 and SML Mode 6.2 on Ubuntu 12.10. What should I do?
Don't use newline-and-indent.
You can use reindent-then-new-and-indent or electric-indent-mode instead.
try in the .emacs file:
(setq default-tab-width 4);
(setq-default indent-tabs-mode nil);
(global-set-key (kbd "TAB") 'self-insert-command);
I'm no wizard but that worked for me.

Following up on Stefan's (now 4 year old...) suggestion, you can auto-enable the minor mode electric-indent-mode for sml-mode by putting this:
(push (lambda () electric-indent-local-mode 1) sml-mode-hook)
somewhere in your emacs initialization code.
Or, you might prefer:
(use-package sml-mode
:config
(push (lambda () electric-indent-local-mode 1) sml-mode-hook))
This seems to me to produce reasonably sane behavior for indenting code in sml-mode.
I'd like to map a command in emacs to a key-binding. I want the command Control-l to have the same effect as the command Alt-x goto-line followed by a return (since that command first needs a return to be invoked and then a line number).
I modified the init file as follows:
(define-key (M-x goto-line) '\C-l)
but that didn't work. The error was that define-key was being given more than 1 arguments.
Does anyone know how to reset key-bindings in emacs?
Thanks!
M-g g is the default shortcut for goto-line. You might want to try that.
To redefine C-l use:
(global-set-key (kbd "C-l") 'goto-line)
Easiest way to customize lots of keybindings is to install John Wiegley's bind-key module, which is a part of use-package Lisp package. Solution in your init.el:
(require 'bind-key)
(bind-key "C-l" 'goto-line)
Minor modes keys usually override global keys, so if you don't want such behavior, use function bind-key* instead. The package is on MELPA, if you don't know what is it, quickly learn about Emacs package management (should take you 2 minutes to set up MELPA as your repository).
The main problem with keybindings in Emacs is that minor modes keys often override your custom ones. In vanilla Emacs people workaround by creating a minor mode for your own keybindings. If you really wanna understand how Emacs keys work, read Key Bindings # Emacs Manual and Keymaps # Elisp Manual carefully.
I have set as (global-set-key (kbd "C-x g") 'goto-line). You can use that or (global-set-key (kbd "C-l") 'goto-line). I would personally do not touch the C-l key from its default behavior.
If you must use M-x define-key, use
(define-key global-map (kbd "C-l") 'goto-line). The 1st argument to define-key is a KEYMAP.
I've tried various version to no avail:
(global-set-key (kbd "C-<space>") 'tempo-complete-tag)
(global-set-key [C-space] 'tempo-complete-tag)
I'm using CUA mode and running Emacs on Ubuntu, version: GNU Emacs 23.1.50.1 (x86_64-pc-linux-gnu, GTK+ Version 2.18.0)
of 2009-09-27 on crested, modified by Debian
When I run tempo-complete-tag manually it tells me it is bound to C-space but C-space still runs cua-set-mark (or if CUA is disable, set-mark-command).
How can I rebind the C-space shortcut in Emacs to a command I decide?
C-h k (key) will tell you how Emacs refers to a given key (which is "C-SPC" in this instance). (global-set-key (kbd "C-SPC") 'tempo-complete-tag) will do what you want.
I always use the (kbd) function for key-bindings, as it allows you to refer to the key the same way it is typically written everywhere else.
Do keep in mind that C-SPC is a standard set-mark-command binding! Personally I'd pick something different :)
Also keep in mind that "global-set-key" will only do what you want, if your mode doesn't override it. I'm too lazy to load tempo to see if it does indeed override C-SPC, but it might well do so, in which case, you want to put this in your .emacs:
(add-hook 'tempo-mode-hook
(lambda ()
(local-set-key (kbd "C-SPC") 'tempo-complete-tag)
))
Alternative syntax for key binding is via vector:
(global-set-key [?\M-\ ] 'cycle-spacing)
(global-set-key [?\C-\ ] 'tempo-complete-tag)
