I am trying to make a keyboard macro that prints a LaTeX macro and places the cursor inside it.
For example, I have the following placed in my .emacs file:
(global-set-key (kbd "C-c v") "\\bibleverse{}()")
I would like to set the cursor inside the curly brackets
(global-set-key (kbd "C-c v") "\\bibleverse{<cursor position>}()")
How would I do this? Is there a macro for cursor position in emacs lisp?
(defun latex-bibleverse-snippet ()
(interactive)
(insert "\\bibleverse{}()")
(backward-char 3))
(global-set-key (kbd "C-c v") 'latex-bibleverse-snippet)
Maybe a quick and dirty answer. Or you can take a look at YASnippet, or Predictive mode(provide IntelliSense features for some major modes (currently: LaTeX, Texinfo, HTML). ) :-)

I've been using emacs for a little while now and am still trying to get the hang of elisp. In my init.el, I have the following lines:
(define-key evil-insert-state-map (kbd "RET") 'newline-and-indent)
(add-hook 'org-mode-hook (lambda () (define-key evil-insert-state-map (kbd "RET") 'newline)))
The intended effect of these two lines of elisp is to disable automatic indentation in org-mode only, but keep automatic indentation for every other mode. However, while this code does disable automatic indentation for org-mode, it has the unintended effect of disabling it for everything else as well. Does anyone know of a way to achieve the desired effect?
You're looking for evil-define-key:
(evil-define-key 'insert org-mode-map (kbd "RET") 'newline)
This will define return to call newline in insert state only in org-mode. What your hook was doing was redefining the global insert state map every time you opened an org buffer.
I want to map C-f C-b as moving forward and backward by a fixed amount of lines in a file.
I did this:
(global-set-key (kbd "C-f") 'next-line)
(global-set-key (kbd "C-b") 'previous-line)
but I don't know how to specify an argument before the next-line command. I guess I should use digit-argument but I am unable to write the command in a correct way.
You've changed your question to be about how to bind directly to key sequences
This binds C-c l to C-u 5 C-n
(global-set-key (kbd "C-c l") (kbd "C-u 5 C-n"))
One of the possible alternatives would be define a new function:
(defun my-next-line ()
(interactive)
(next-line 5))
(global-set-key (kbd "C-f") 'my-next-line)
Otherwise, if it is just something you can accomplish with the keyboard you might want to use
M-x name-last-kbd-macro
and save it in your .emacs file
M-x insert-kbd-macro
and have emacs implement the function for you.
It will just get the name you gave in your call to name-last-kbd-macro
I'd like to have M-u to insert an underscore when I am in isearch (isearch-regexp and also the reverse variants).
Neither
(define-key isearch-mode-map (kbd "M-u") 'insert-underscore)
nor
(add-hook 'isearch-mode-hook
(lambda ()
(local-set-key (kbd "M-u") 'insert-underscore)
))
insert-underscore is my function that simply inserts "_". It works in the main frame and also in minibuffer, but I can't get it working in isearch...
Thank you!
Isearch doesn't use regular commands. (kbd "_") along with every other
printable character is bound to a special command in isearch-mode-map. It's
not obvious, but a lot of things happen in "isearch-mode" when you press a
key. Display is refreshed with new results, wrapping is a possibility, etc, etc,
You'd have to manipulate raw keyboard events to get this to work.
(defun underscore ()
(interactive)
(isearch-unread-key-sequence (list ?_)))
(define-key isearch-mode-map (kbd "M-u") 'underscore)
Note that this code is not robust; for example, numeric prefix does not work.
EDIT: After letting percolate in my mind for a while, it occured to me that this is the exact use-case for translation keymaps
(define-key key-translation-map (kbd "M-u") (kbd "_"))
Ain't Emacs grand?
I am using thhs code in the .emacs file to permanently enable the hs-minor-mode and to change the shortcut:
(setq-default hs-minor-mode t)
(global-set-key (kbd "C-c C-h") (kbd "C-c # C-h")) ;;hiding block of code
(global-set-key (kbd "C-c C-r") (kbd "C-c # C-s")) ;;revealing block of code
But the mode is not activated automatically. what should i do?
You can turn on hs-minor-mode for a specific mode like C, C++ mode using c-mode-common-hook.
(add-hook 'c-mode-common-hook #'hs-minor-mode)
In Emacs 24 or later, you can turn it on in all programming modes using prog-mode-hook.
(add-hook 'prog-mode-hook #'hs-minor-mode)
If you want it to be truly global, this does the trick:
(define-globalized-minor-mode global-hs-minor-mode
hs-minor-mode hs-minor-mode)
(global-hs-minor-mode 1)
If you want to enable it everywhere, and start the buffer with the code folded by hs-hide-all, do
(defun my-hide-all()
(interactive)
(hs-minor-mode)
(hs-hide-all))
(add-hook 'prog-mode-hook 'my-hide-all)
I'm trying to have C-<return> map to move-end-of-line then newline-and-indent
In my .emacs I have been playing around with the following:
(global-set-key (kbd "C-<return>") '(progn (move-end-of-line) (newline-and-indent)))
And
(defun c-ret()
'(move-end-of-line newline-and-indent))
(global-set-key (kbd "C-<return>") 'c-ret)
but neither work.
Pointers?
You are quoting the commands.
That implies that they won't be executed. You also need the (interactive) to signify to emacs that it's callable from the keyboard.
Then, you need to have your parameters to your functions correct.
Further, I think your nomenclature for return is wrong.
Your basic misunderstanding here is knowing how eLisp works. That's okay, it's an arcane programming language.
' a.k.a QUOTE is pretty much a Lisp-specific special instruction. It says, "Don't evaluate what comes after me", and returns the unevaluated parameter.
So '(foo bar) is desugared into (QUOTE (FOO BAR)), which returns (FOO BAR).
Try this:
(defun c-ret()
(interactive)
(move-end-of-line nil)
(newline-and-indent))
(global-set-key (kbd "C-RET") 'c-ret)
You can do this without writing any code yourself. See http://www.emacswiki.org/emacs/KeyboardMacrosTricks for instructions on capturing a sequence of commands as a keyboard macro, naming it, and saving it in your .emacs. You can then give the new command a key binding of your choice with e.g. (global-set-key (kbd "C-c i") 'new-command-name).
If you want a one-line solution, this will work too:
(global-set-key (kbd "C-<return>") (lambda () (interactive) (move-end-of-line nil) (newline-and-indent)))
